Ready for 2nd release to - comp.sources.unix. Lots of work on the manual. - -Mon Apr 5 18:28:05 1993 Gray Watson () - - * Finished adding token "check-funcs" to check the arguments of - some common string functions to see whether they are in the heap. - if so it tries to verify that the pointers are good. - -Sun Apr 4 21:24:45 1993 Gray Watson () - - * Added token "log-unknown" to dump non-free unknown pointers as - well as known ones. Also cleaned up the displaying of the - pointers. - - * comp.sources.unix is almost ready to post so lots of last minute - cleanups in the manual, etc. - - * Started integration of function argument checking. - -Tue Mar 30 19:36:27 1993 Gray Watson () - - * Changed malloc.h defines so malloc routines are handled as well - as the ALLOC macros. - - * malloc_dbg program now reports on the token NAME and values. - - * Added initial string files for string support in the future. - - * A number of minor changes: fixed gcc compilation problems per - Scott's help, combined malloc_lp.h into malloc.h, cleaned most .h - and .c files. - -Fri Mar 26 04:00:14 1993 Gray Watson () - - * Fixed post 1.1.6 problem with chunk.c. Boy do I need some - automated testing tools. Discovered the illusive localtime - fence-post error. Had a hard time tracking it down. Maybe due to - the fact that the checks were not being made on dblock fence posts - before? - - * Released version 1.1.6 - - * Found some problems with malloc debug codes. Use of DB_FENCE - and CHECK_LISTS and some others were improper. A MALLOC_DEBUG - value of 0x403000 would crash all malloc programs. :-) - - * Added some better comments to all files and cleaned up most - files too. - -Fri Mar 12 18:35:02 1993 Gray Watson () - - * Released version 1.1.5. - -Sat Feb 13 17:25:43 1993 Gray Watson () - - * Finished add a number of const operators to improve coding per - scott's recommendations. - -Sat Jan 30 12:33:43 1993 Gray Watson () - - * Released version 1.1.4 - - * Took out the check_vars call inside of malloc_strerror since - _malloc_perror calls malloc_strerror which would go quickly - recursive.

Yeach. malloc_debug -> - malloc_dbg. - -Sat Nov 14 15:59:53 1992 Gray Watson () - - * Added all external functions to configure and conf.h even though - the library assumes that some functions will be resolved. Also - upgraded the version number to 1.01gamma (oooooh). - - * Added print-perror debug token for logging messages to STDERR as - well as log-files. Removed stdio from the malloc library to make - sure it does not go recursive (alloc for stderr) at a bad time. - -Wed Nov 11 18:19:49 1992 Gray Watson () - - * Moved the heap_check calls from chunk.c over to malloc so we can - be guaranteed that it gets called only once per user call. - chunk's routines often cross-call each other meaning that - heap-check was being run 5 times in realloc. YEACH!! - -Tue Nov 10 17:55:53 1992 Gray Watson () - - * Added two new debug-tokens: log-blocks and heap-check-map. Also - made sure that heap_check was being called from everywhere. - Updated the manual and corresponding files. - - * Added library functions that may not be defined. Updated the - conf.h.in and configure.in files to improve confiurability. - Upgraded the manual which still needs a lot of work (sigh). - -Mon Nov 9 19:21:25 1992 Gray Watson () - - * Added configure, configure.in, conf.h.in, and Makefile.in to try - and conform with autoconf specs. What a bear. The documentation - for autoconf needs a whole bunch more examples, etc. Sigh. - Removed all the MEMORY and STRING defines, etc. - -Thu Nov 5 22:13:18 1992 Gray Watson () - - * Released version 1.01b. Sending it off to some folks. - - * Lots and lots of changes. Translated all programs into non-ansi - C dependence and then went back again when I found some problems - with my macros. :-) Took out all (and I mean all) Antaire - dependencies and defines. - -Thu Oct 22 00:47:18 1992 Gray Watson () - - * Ran through most of the debug-flag functionality testing and - tweaking. Found some bugs on dblock handling and some messed up - logic with the way the LOG flags were working. - - * malloc_debug is looking good. It now outputs C or Bourne shell - code and seems to work in both environments. What do sh folks use - in the place of c-shell aliasing? I guess use bash. :-) - -Wed Oct 21 03:27:35 1992 Gray Watson () - - * Major changes. I sort of went overboard tonight. I integrated - the new malloc_debug program which sets all the debug variables - for you. I also added a .mallocrc which you can define with tags - exactly the functionality you want to happen. No more levels!! - - * Did some renaming of files, cleaned up some other things, - had to rework a number of items to get new debug flags working. - -Tue Oct 20 18:06:36 1992 Gray Watson () - - * Removed useful.h requirements and integrated necessary - definitions into malloc.h. - - * Transferred malloc.txt documentation into malloc.texinfo. Boy - is it nifty!! And damn easy!!! - - * Major changes to improve general machine independence. Added - malloc_mach.h. Moved alloc.[ch] to malloc.[ch] for sanity - reasons. - -Tue Oct 13 16:14:17 1992 Gray Watson () - - * Made various cosmetic changes. Fixed realloc inbound pointer - checking per MALLOC_ADDRESS. Fixed problem with MALLOC_ADDRESS - initialization to NULL causing free to "find" NULL pointers. :-) - - * Separated the PERROR debug level and the KILL_SELF level. Now - (by default) all memory errors are logged at level 1 and above and - malloc kills itself at level 2 and above. - -Mon Sep 28 23:24:36 1992 Gray Watson () - - * Added MALLOC_ADDRESS support for free. MALLOC_ADDRESS counts - now also apply to frees also. - -Mon Sep 21 20:39:38 1992 Gray Watson () - - * Fixed some size problems with bounds checking enabled. - - * Made free be able to report who freed a pointer. I don't know - why this wasn't caught before. free wasn't even using its - file/line arguments. - -Thu Sep 3 03:23:39 1992 Gray Watson () - - * Added ability to realloc a NULL pointer with an ifdef to - disable. Useful in realloc loops where the first time you don't - have to alloc it. - -Fri Aug 14 15:54:03 1992 Gray Watson () - - * Added a bunch of new environmental variables features: - MALLOC_ADDRESS now can have a :# argument. MALLOC_START now has - two formats, the old number and new file:line. Looks nice! - - * Made a pass through chunk.c and fixed a number of problems where - debug output pnt/size did not match user-supplied information. - - * Moved most of the debug variables into alloc.c from chunk.c and - added a standardized check_debug_vars() checking routine. - -Tue Jul 21 16:06:13 1992 Gray Watson () - - * Fixed malloc count statistics. Removed duplicate malloc_count - variable from a number of places. - -Mon Mar 23 10:49:25 1992 Gray Watson () - - * Released version 0.04 - - * New env variable features. - -Thu Mar 12 19:28:34 1992 Gray Watson () - - * Fixed a large problem with chunk.c not reporting the correct - memory address when listing unfreed memory. This was discovered - when MALLOC_ADDRESS was not working correctly. - - * Started ChangeLog. - -------------------------------------------------------------------------------- -$Id: ChangeLog,v 1.345 2007/05/14 17:23:42 gray Exp $ -------------------------------------------------------------------------------- diff --git a/dmalloc-5.5.2/.svn/text-base/INSTALL.svn-base b/dmalloc-5.5.2/.svn/text-base/INSTALL.svn-base deleted file mode 100644 index a4199e2..0000000 --- a/dmalloc-5.5.2/.svn/text-base/INSTALL.svn-base +++ /dev/null @@ -1,3377 +0,0 @@ -------------------------------------------------------------------------------- - -2.1 How to Install the Library -============================== - -To configure, compile, and install the library, follow these steps -carefully. - - 1. Make sure you have downloaded the latest version of the library - available from the home page at URL `http://dmalloc.com/'. - - 2. The release files have a `.tgz' file extension which means that - they are a tar'd gzip'd directory of files. You will need to - ungzip and then untar the release file into your source work - directory. You may have to rename the file to `.tar.gz' to get - some old zip programs to handle the file correctly. - - 3. You may want to edit or at least review the settings in - `settings.dist' to tune specific features of the library. The - `configure' script will copy this file to `settings.h' which is - where you should be adding per-architecture settings. - - 4. Type `sh ./configure' to configure the library. You may want to - first examine the `config.help' file for some information about - configure. You may want to use the `--disable-cxx' option if you - do not want the Makefile to build the C++ version of dmalloc. You - may want to use the `--enable-threads' option to build the - threaded version of dmalloc. You may want to use the - `--enable-shlib' option to build the shared versions of the - dmalloc libraries. `sh ./configure --help' lists the available - options to configure. Configure should generate the `Makefile' - and configuration files automatically. - - 5. You may want to examine the `Makefile' and `conf.h' files created - by configure to make sure it did its job correctly. - - 6. You might want to tune the settings in `settings.h' file to tune - the library to the local architecture. This file contains relevant - settings if you are using pthreads or another thread library. - *Note Using With Threads::. The `configure' script created this - file from the `settings.dist' file. Any permanent changes to these - settings should made to the `settings.dist' file. You then can run - `config.status' to re-create the `settings.h' file. - - 7. The `DMALLOC_SIZE' variable gets auto-configured in `dmalloc.h.2' - but it may not generate correct settings for all systems. You may - have to alter the definitions in this file to get things to stop - complaining when you go to compile about the size arguments to - malloc routines. Comments on this please. - - 8. Typing `make' should be enough to build `libdmalloc.a', and - `dmalloc' program. If it does not work, please see if there are - any notes in the contrib directory about your system-type. If not - and you figure your problem out, please send me some notes so - future users can profit from your experiences. - - _NOTE_: You may experience some errors compiling some of the - `return.h' assembly macros which attempt to determine the callers - address for logging purposes. *Note Portability::. You may want - to first try disabling any compiler optimization flags. If this - doesn't work then you may need to disable the `USE_RETURN_MACROS' - variable in the `settings.h' file. - - _NOTE_: The code is dependent on an ANSI-C compiler. If the - configure script gives the `WARNING' that you do not have an ANSI-C - compiler, you may still be able to add some sort of option to your - compiler to make it ANSI. If there such is an option, please send - it to the author so it can be added to the configure script. - - 9. If you use threads and did not add the `--enable-threads' argument - to configure, typing `make threads' should be enough to build - `libdmallocth.a' which is the threaded version of the library. - This may or may not work depending on the configuration scripts - ability to detect your local thread functionality. Feel free to - send me mail with improvements. - - See the section of the manual on threads for more information about - the operation of the library with your threaded program. *Note - Using With Threads::. - - 10. If you have a C++ compiler installed, the library should have - automatically built `libdmallocxx.a' which is the C++ version of - the library. If it was not done automatically, you can build it by - typing `make cxx'. You should link this library into your C++ - programs instead of `libdmalloc.a'. See the `dmallocc.cc' C++ - file which contains basic code to overload the `new', `new[]', - `delete', and `delete[]' C++ operators. My apologies on the - minimal C++ support. I am still living in a mostly C world. Any - help improving this interface without sacrificing portability - would be appreciated. - - 11. Typing `make light' should build and run the `dmalloc_t' test - program through a set of light trials. By default this will - execute `dmalloc_t' 5 times - each time will execute 10,000 malloc - operations in a very random manner. Anal folks can type `make - heavy' to up the ante. Use `dmalloc_t --usage' for the list of all - `dmalloc_t' options. - - 12. Typing `make install' should install the `libdmalloc.a' library in - `/usr/local/lib', the `dmalloc.h' include file in - `/usr/local/include', and the `dmalloc' utility in - `/usr/local/bin'. You may also want to type `make installth' to - install the thread library into place and/or `make installcc' to - install the C++ library into place. - - You may have specified a `--prefix=PATH' option to configure in - which case `/usr/local' will have been replaced with `PATH'. - - - See the "Getting Started" section to get up and running with the -library. *Note Getting Started::. - - -------------------------------------------------------------------------------- - -2.2 Getting Started with the Library -==================================== - -This section should give you a quick idea on how to get going. -Basically, you need to do the following things to make use of the -library: - - 1. Make sure you have downloaded the latest version of the library - available from the home page at URL `http://dmalloc.com/'. - - 2. Follow the installation instructions on how to configure, make, - and install the library (i.e. type: `make install'). *Note - Installation::. - - 3. You need to make sure that the library configuration and build - process above was able to locate one of the `on_exit' function, - `atexit' function, or had compiler destructor support. If one of - these functions or support is available then the dmalloc library - should be able to automatically shut itself down when the program - exits. This causes the memory statistics and unfreed information - to be dumped to the log file. However, if your system has none of - the above, then you will need to call `dmalloc_shutdown' yourself - before your program exits. - - 4. To get the dmalloc utility to work you need to add an alias for - dmalloc to your shell's runtime configuration file if supported. - The idea is to have the shell capture the dmalloc program's output - and adjust the environment. - - After you add the alias to the shell config file you need to log - out and log back in to have it take effect, or you can execute the - appropriate command below on the command line directly. After you - setup the alias, if you enter `dmalloc runtime' and see any output - with DMALLOC_OPTIONS in it then the alias did not take effect. - - Bash, ksh, and zsh (`http://www.zsh.org/') users should add the - following to their `.bashrc', `.profile', or `.zshrc' file - respectively (notice the `-b' option for bourne shell output): - - function dmalloc { eval `command dmalloc -b $*`; } - - If your shell does not support the `command' function then try: - - function dmalloc { eval `\dmalloc -b $*`; } - or - function dmalloc { eval `/usr/local/bin/dmalloc -b $*`; } - - If you are still using csh or tcsh, you should add the following to - your `.cshrc' file (notice the `-C' option for c-shell output): - - alias dmalloc 'eval `\dmalloc -C \!*`' - - If you are using rc shell, you should add the following to your - `.rcrc' file (notice the `-R' option for rc-shell output): - - fn dmalloc {eval `{/usr/local/bin/dmalloc $*}} - - 5. Although not necessary, you may want to include `dmalloc.h' in - your C files and recompile. This will allow the library to report - the file/line numbers of calls that generate problems. *Note - Allocation Macros::. It should be inserted at the _bottom_ of - your include files as to not conflict with wother includes. You - may want to ifdef it as well and compile with `cc -DDMALLOC ...': - - /* other includes above ^^^ */ - - #ifdef DMALLOC - #include "dmalloc.h" - #endif - - 6. Another optional task is to compile all of your source with the - `dmalloc.h' with the `DMALLOC_FUNC_CHECK' compilation flag. This - willallow the library to check all of the arguments of a number of - common string and utility routines. *Note Argument Checking::. - - cc -DDMALLOC -DDMALLOC_FUNC_CHECK file.c - - 7. Link the dmalloc library into your program. The dmalloc library - should probably be placed at or near the end of the library list. - - 8. Enable the debugging features by typing `dmalloc -l logfile -i 100 - low' (for example). You should not see any messages printed by - the dmalloc utility (see NOTE below). This will: - - * Set the malloc logfile name to `logfile' (`-l logfile'). For - programs which change directories, you may want to specify the - full path to your logfile. - - * Have the library check itself every 100 iterations (`-i 100'). - This controls how fast your program will run. Larger numbers - check the heap less and so it will run faster. Lower numbers - will be more likely to catch memory problems. - - * Enable a number of debug features (`low'). You can also try - `runtime' for minimal checking or `medium' or `high' for more - extensive heap verification. - - * By default, the low, medium, and high values enable the - `error-abort' token which will cause the library to abort and - usually dump core immediately upon seeing an error. *Note - Dumping Core::. You can disable this feature by entering - `dmalloc -m error-abort' (-m for minus) to remove the - `error-abort' token and your program will just log errors and - continue. - - - `dmalloc --usage' will provide verbose usage info for the dmalloc - program. *Note Dmalloc Program::. - - You may also want to install the `dmallocrc' file in your home - directory as `.dmallocrc'. This allows you to add your own - combination of debug tokens. *Note RC File::. - - _NOTE_: The output from the dmalloc utility should be captured by - your shell. If you see a bunch of stuff which includes the string - `DMALLOC_OPTIONS' then the alias you should have created above is - not working and he environmental variables are not being set. Make - sure you've logged out and back in to have the alias take effect. - - 9. Run your program, examine the logfile that should have been - created by `dmalloc_shutdown', and use its information to help - debug your program. - - - -File: dmalloc.info, Node: Allocation Basics, Next: Features, Prev: Getting Started, Up: Overview - -2.3 Basic Description of Terms and Functions -============================================ - -* Menu: - -* Basic Definitions:: General memory terms and concepts. -* Malloc Functions:: Functionality supported by all malloc libs. - - -File: dmalloc.info, Node: Basic Definitions, Next: Malloc Functions, Prev: Allocation Basics, Up: Allocation Basics - -2.3.1 General Memory Terms and Concepts ---------------------------------------- - -Any program can be divided into 2 logical parts: text and data. Text is -the actual program code in machine-readable format and data is the -information that the text operates on when it is executing. The data, -in turn, can be divided into 3 logical parts according to where it is -stored: "static", "stack", and "heap". - - Static data is the information whose storage space is compiled into -the program. - - /* global variables are allocated as static data */ - int numbers[10]; - - main() - { - ... - } - - Stack data is data allocated at runtime to hold information used -inside of functions. This data is managed by the system in the space -called stack space. - - void foo() - { - /* this local variable is stored on the stack */ - float total; - ... - } - - main() - { - foo(); - } - - Heap data is also allocated at runtime and provides a programmer with -dynamic memory capabilities. - - main() - { - /* the address is stored on the stack */ - char * string; - ... - - /* - * Allocate a string of 10 bytes on the heap. Store the - * address in string which is on the stack. - */ - string = (char *)malloc(10); - ... - - /* de-allocate the heap memory now that we're done with it */ - (void)free(string); - ... - } - - It is the heap data that is managed by this library. - - Although the above is an example of how to use the malloc and free -commands, it is not a good example of why using the heap for runtime -storage is useful. - - Consider this: You write a program that reads a file into memory, -processes it, and displays results. You would like to handle files with -arbitrary size (from 10 bytes to 1.2 megabytes and more). One problem, -however, is that the entire file must be in memory at one time to do the -calculations. You don't want to have to allocate 1.2 megabytes when you -might only be reading in a 10 byte file because it is wasteful of system -resources. Also, you are worried that your program might have to handle -files of more than 1.2 megabytes. - - A solution: first check out the file's size and then, using the -heap-allocation routines, get enough storage to read the entire file -into memory. The program will only be using the system resources -necessary for the job and you will be guaranteed that your program can -handle any sized file. - - -File: dmalloc.info, Node: Malloc Functions, Prev: Basic Definitions, Up: Allocation Basics - -2.3.2 Functionality Supported by All Malloc Libraries ------------------------------------------------------ - -All malloc libraries support 4 basic memory allocation commands. These -include "malloc", "calloc", "realloc", and "free". For more -information about their capabilities, check your system's manual pages -- in unix, do a `man 3 malloc'. - - -- Function: void *malloc ( unsigned int SIZE ) - Usage: `pnt = (type *)malloc(size)' - - The malloc routine is the basic memory allocation routine. It - allocates an area of `size' bytes. It will return a pointer to - the space requested. - - - -- Function: void *calloc ( unsigned int NUMBER, unsigned intSIZE ) - Usage: `pnt = (type *)calloc(number, size)' - - The calloc routine allocates a certain `number' of items, each of - `size' bytes, and returns a pointer to the space. It is - appropriate to pass in a `sizeof(type)' value as the size argument. - - Also, calloc nulls the space that it returns, assuring that the - memory is all zeros. - - - -- Function: void *realloc ( void *OLD_PNT, unsigned int NEW_SIZE ) - Usage: `new_pnt = (type *)realloc(old_pnt, new_size)' - - The realloc function expands or shrinks the memory allocation in - `old_pnt' to `new_size' number of bytes. Realloc copies as much - of the information from `old_pnt' as it can into the `new_pnt' - space it returns, up to `new_size' bytes. If there is a problem - allocating this memory, 0L will be returned. - - If the `old_pnt' is 0L then realloc will do the equivalent of a - `malloc(new_size)'. If `new_size' is 0 and `old_pnt' is not 0L, - then it will do the equivalent of `free(old_pnt)' and will return - 0L. - - - -- Function: void free ( void *PNT ) - Usage: `free(pnt)' - - The free routine releases allocation in `pnt' which was returned by - malloc, calloc, or realloc back to the heap. This allows other - parts of the program to re-use memory that is not needed anymore. - It guarantees that the process does not grow too big and swallow a - large portion of the system resources. - - - _WARNING_: there is a quite common myth that all of the space that -is returned by malloc libraries has already been cleared. _Only_ the -`calloc' routine will zero the memory space it returns. - - -File: dmalloc.info, Node: Features, Next: How It Works, Prev: Allocation Basics, Up: Overview - -2.4 General Features of the Library -=================================== - -The debugging features that are available in this debug malloc library -can be divided into a couple basic classifications: - -file and line number information - One of the nice things about a good debugger is its ability to - provide the file and line number of an offending piece of code. - This library attempts to give this functionality with the help of - "cpp", the C preprocessor. *Note Allocation Macros::. - -return-address information - To debug calls to the library from external sources (i.e. those - files that could not use the allocation macros), some facilities - have been provided to supply the caller's address. This address, - with the help of a debugger, can help you locate the source of a - problem. *Note Return Address::. - -fence-post (i.e. bounds) checking - "Fence-post" memory is the area immediately above or below memory - allocations. It is all too easy to write code that accesses above - or below an allocation - especially when dealing with arrays or - strings. The library can write special values in the areas around - every allocation so it will notice when these areas have been - overwritten. *Note Fence-Post Overruns::. - - _NOTE_: The library cannot notice when the program _reads_ from - these areas, only when it writes values. Also, fence-post checking - will increase the amount of memory the program allocates. - -heap-constancy verification - The administration of the library is reasonably complex. If any - of the heap-maintenance information is corrupted, the program will - either crash or give unpredictable results. - - By enabling heap-consistency checking, the library will run - through its administrative structures to make sure all is in - order. This will mean that problems will be caught faster and - diagnosed better. - - The drawback of this is, of course, that the library often takes - quite a long time to do this. It is suitable to enable this only - during development and debugging sessions. - - _NOTE_: the heap checking routines cannot guarantee that the tests - will not cause a segmentation-fault if the heap administration - structures are properly (or improperly if you will) overwritten. - In other words, the tests will verify that everything is okay but - may not inform the user of problems in a graceful manner. - -logging statistics - One of the reasons why the debug malloc library was initially - developed was to track programs' memory usage - specifically to - locate "memory leaks" which are places where allocated memory is - never getting freed. *Note Memory Leaks::. - - The library has a number of logging capabilities that can track - un-freed memory pointers as well as runtime memory usage, memory - transactions, administrative actions, and final statistics. - -examining freed memory - Another common problem happens when a program frees a memory - pointer but goes on to use it again by mistake. This can lead to - mysterious crashes and unexplained problems. - - To combat this, the library can write special values into a block - of memory after it has been freed. This serves two purposes: it - will make sure that the program will get garbage data if it trying - to access the area again, and it will allow the library to verify - the area later for signs of overwriting. - - If any of the above debugging features detect an error, the library -will try to recover. If logging is enabled then an error will be -logged with as much information as possible. - - The error messages that the library displays are designed to give the -most information for developers. If the error message is not -understood, then it is most likely just trying to indicate that a part -of the heap has been corrupted. - - The library can be configured to quit immediately when an error is -detected and to dump a core file or memory-image. This can be examined -with a debugger to determine the source of the problem. The library -can either stop after dumping core or continue running. *Note Dumping -Core::. - - _NOTE_: do not be surprised if the library catches problems with -your system's routines. It took me hours to finally come to the -conclusion that the localtime call, included in SunOS release 4.1, -overwrites one of its fence-post markers. - - -File: dmalloc.info, Node: How It Works, Prev: Features, Up: Overview - -2.5 How the Library Checks Your Program -======================================= - -This is one of the newer sections of the library implying that it is -incomplete. If you have any questions or issues that you'd like to see -handled here, please let me know. - - The dmalloc library replaces the heap library calls normally found in -your system libraries with its own versions. When you make a call to -malloc (for example), you are calling dmalloc's version of the memory -allocation function. When you allocate memory with these functions, the -dmalloc library keeps track of a number of pieces of debugging -information about your pointer including: where it was allocated, -exactly how much memory was requested, when the call was made, etc.. -This information can then be verified when the pointer is freed or -reallocated and the details can be logged on any errors. - - Whenever you reallocate or free a memory address, the dmalloc library -always performs a number of checks on the pointer to make sure that it -is valid and has not been corrupted. You can configure the library to -perform additional checks such as detected fence-post writing. The -library can also be configured to overwrite memory with non-zeros (only -if calloc is not called) when it is allocated and erase the memory when -the pointers are freed. - - In addition to per-pointer checks, you can configure the library to -perform complete heap checks. These complete checks verify all -internal heap structures and include walking all of the known allocated -pointers to verify each one in turn. You need this level of checking -to find random pointers in your program which got corrupted but that -won't be freed for a while. To turn on these checks, you will need to -enable the `check-heap' debug token. *Note Debug Tokens::. By default -this will cause the heap to be fully checked each and every time -dmalloc is called whether it is a malloc, free, realloc, or another -dmalloc overloaded function. - - Performing a full heap check can take a good bit of CPU and it may be -that you will want to run it sporadically. This can be accomplished in -a couple different ways including the '-i' interval argument to the -dmalloc utility. *Note Dmalloc Program::. This will cause the check to -be run every N-th time. For instance, 'dmalloc -i 3' will cause the -heap to be checked before every 3rd call to a memory function. Values -of 100 or even 1000 for high memory usage programs are more useful than -smaller ones. - - You can also cause the program to start doing detailed heap checking -after a certain point. For instance, with 'dmalloc -s 1000' option, you -can tell the dmalloc library to enable the heap checks after the 1000th -memory call. Examine the dmalloc log file produced and use the -iteration count if you have `LOG_ITERATION_COUNT' enabled in your -`settings.h' file. - - The start option can also have the format `file:line'. For -instance, if it is set to `dmalloc_t.c:126', dmalloc will start -checking the heap after it sees a dmalloc call from the `dmalloc_t.c' -file, line number 126. If you use `dmalloc_t.c:0', with a 0 line -number, then dmalloc will start checking the heap after it sees a call -from anywhere in the `dmalloc_t.c' file. - - -File: dmalloc.info, Node: Programming, Next: Dmalloc Program, Prev: Overview, Up: Top - -3 How to Program with the Library -********************************* - -* Menu: - -* Allocation Macros:: Macros providing file and line information. -* Return Address:: Getting caller address information. -* Argument Checking:: Checking of function arguments. -* Dumping Core:: Generating a core file on errors for debugging. -* Extensions:: Additional non-standard routines. -* Error Codes:: Description of the internal error numbers. -* Disabling the Library:: How to disable the library. -* Using With C++:: Using the library with C++. -* Using With a Debugger:: Using a debugger with the library. -* Using With Threads:: Using the library with a thread package. -* Using With Cygwin:: Using the library with Cygwin environment. -* Debugging A Server:: Debugging memory in a server or cgi-bin process. -* Logfile Details:: Explanation of the Logfile Output. -* Other Hints:: Various other hints that may help. - - -File: dmalloc.info, Node: Allocation Macros, Next: Return Address, Prev: Programming, Up: Programming - -3.1 Macros Providing File and Line Information -============================================== - -By including `dmalloc.h' in your C files, your calls to malloc, calloc, -realloc, recalloc, memalign, valloc, strdup, and free are replaced with -calls to _dmalloc_malloc, _dmalloc_realloc, and _dmalloc_free with -various flags. Additionally the library replaces calls to xmalloc, -xcalloc, xrealloc, xrecalloc, xmemalign, xvalloc, xstrdup, and xfree -with associated calls. - - These macros use the c-preprocessor `__FILE__' and `__LINE__' macros -which get replaced at compilation time with the current file and -line-number of the source code in question. The routines use this -information to produce verbose reports on memory problems. - - not freed: '0x38410' (22 bytes) from 'dmalloc_t.c:92' - - This line from a log file shows that memory was not freed from file -`dmalloc_t.c' line 92. *Note Memory Leaks::. - - You may notice some non standard memory allocation functions in the -above list. Recalloc is a routine like realloc that reallocates -previously allocated memory to a new size. If the new memory size is -larger than the old, recalloc initializes the new space to all zeros. -This may or may not be supported natively by your operating system. -Memalign is like malloc but should insure that the returned pointer is -aligned to a certain number of specified bytes. Currently, the memalign -function is not supported by the library. It defaults to returning -possibly non-aligned memory for alignment values less than a block-size. -Valloc is like malloc but insures that the returned pointer will be -aligned to a page boundary. This may or may not be supported natively -by your operating system but is fully supported by the library. Strdup -is a string duplicating routine which takes in a null terminated string -pointer and returns an allocated copy of the string that will need to be -passed to free later to deallocate. - - The X versions of the standard memory functions (xmalloc, xfree, -etc.) will print out an error message to standard error and will stop -if the library is unable to allocate any additional memory. It is -useful to use these routines instead of checking everywhere in your -program for allocation routines returning NULL pointers. - - _WARNING_: If you are including the `dmalloc.h' file in your -sources, it is recommended that it be at the end of your include file -list because dmalloc uses macros and may try to change declarations of -the malloc functions if they come after it. - - -File: dmalloc.info, Node: Return Address, Next: Argument Checking, Prev: Allocation Macros, Up: Programming - -3.2 Getting Caller Address Information -====================================== - -Even though the allocation macros can provide file/line information for -some of your code, there are still modules which either you can't -include `dmalloc.h' (such as library routines) or you just don't want -to. You can still get information about the routines that call dmalloc -function from the return-address information. To accomplish this, you -must be using this library on one of the supported -architecture/compilers. *Note Portability::. - - The library attempts to use some assembly hacks to get the -return-address or the address of the line that called the dmalloc -function. If you have unfreed memory that does not have associated file -and line information, you might see the following non-freed memory -messages. - - not freed: '0x38410' (22 bytes) from 'ra=0xdd2c' - not freed: '0x38600' (10232 bytes) from 'ra=0x10234d' - not freed: '0x38220' (137 bytes) from 'ra=0x82cc' - - With the help of a debugger, these return-addresses (or ra) can then -be identified. I've provided a `ra_info.pl' perl script in the -`contrib/' directory with the dmalloc sources which seems to work well -with gdb. You can also use manual methods for gdb to find the -return-address location. *Note Translate Return Addresses::. - - -File: dmalloc.info, Node: Argument Checking, Next: Dumping Core, Prev: Return Address, Up: Programming - -3.3 Checking of Function Arguments -================================== - -One potential problem with the library and its multitude of checks and -diagnoses is that they only get performed when a dmalloc function is -called. One solution this is to include `dmalloc.h' and compile your -source code with the `DMALLOC_FUNC_CHECK' flag defined and enable the -`check-funcs' token. *Note Debug Tokens::. - - cc -DDMALLOC -DDMALLOC_FUNC_CHECK file.c - - _NOTE_: Once you have compiled your source with DMALLOC_FUNC_CHECK -enabled, you will have to recompile with it off to disconnect the -library. *Note Disabling the Library::. - - _WARNING_: You should be sure to have `dmalloc.h' included at the -end of your include file list because dmalloc uses macros and may try -to change declarations of the checked functions if they come after it. - - When this is defined dmalloc will override a number of functions and -will insert a routine which knows how to check its own arguments and -then call the real function. Dmalloc can check such functions as -`bcopy', `index', `strcat', and `strcasecmp'. For the full list see -the end of `dmalloc.h'. - - When you call `strlen', for instance, dmalloc will make sure the -string argument's fence-post areas have not been overwritten, its file -and line number locations are good, etc. With `bcopy', dmalloc will -make sure that the destination string has enough space to store the -number of bytes specified. - - For all of the arguments checked, if the pointer is not in the heap -then it is ignored since dmalloc does not know anything about it. - - -File: dmalloc.info, Node: Dumping Core, Next: Extensions, Prev: Argument Checking, Up: Programming - -3.4 Generating a Core File on Errors -==================================== - -If the `error-abort' debug token has been enabled, when the library -detects any problems with the heap memory, it will immediately attempt -to dump a core file. *Note Debug Tokens::. Core files are a complete -copy of the program and it's state and can be used by a debugger to see -specifically what is going on when the error occurred. *Note Using -With a Debugger::. By default, the low, medium, and high arguments to -the library utility enable the `error-abort' token. You can disable -this feature by entering `dmalloc -m error-abort' (-m for minus) to -remove the `error-abort' token and your program will just log errors -and continue. You can also use the `error-dump' token which tries to -dump core when it sees an error but still continue running. *Note -Debug Tokens::. - - When a program dumps core, the system writes the program and all of -its memory to a file on disk usually named `core'. If your program is -called `foo' then your system may dump core as `foo.core'. If you are -not getting a `core' file, make sure that your program has not changed -to a new directory meaning that it may have written the core file in a -different location. Also insure that your program has write privileges -over the directory that it is in otherwise it will not be able to dump -a core file. Core dumps are often security problems since they contain -all program memory so systems often block their being produced. You -will want to check your user and system's core dump size ulimit -settings. - - The library by default uses the `abort' function to dump core which -may or may not work depending on your operating system. If the -following program does not dump core then this may be the problem. See -`KILL_PROCESS' definition in `settings.dist'. - - main() - { - abort(); - } - - If `abort' does work then you may want to try the following setting -in `settings.dist'. This code tries to generate a segmentation fault -by dereferencing a `NULL' pointer. - - #define KILL_PROCESS { int *_int_p = 0L; *_int_p = 1; } - - -File: dmalloc.info, Node: Extensions, Next: Error Codes, Prev: Dumping Core, Up: Programming - -3.5 Additional Non-standard Routines -==================================== - -The library has a number of variables that are not a standard part of -most malloc libraries: - - -- Variable: int dmalloc_errno - This variable stores the internal dmalloc library error number - like errno does for the system calls. It can be passed to - `dmalloc_strerror()' (see below) to get a string version of the - error. It will have a value of zero if the library has not - detected any problems. - - - -- Variable: char* dmalloc_logpath - This variable can be used to set the dmalloc log filename. The env - variable `DMALLOC_LOGFILE' overrides this variable. - - - Additionally the library provides a number of non-standard malloc -routines: - - -- Function: void dmalloc_shutdown ( void ) - This function shuts the library down and logs the final statistics - and information especially the non-freed memory pointers. The - library has code to support auto-shutdown if your system has the - `on_exit()' call, `atexit()' call, or compiler destructor support - (see `conf.h'). If you do not have these, then `dmalloc_shutdown' - should be called right before `exit()' or as the last function in - `main()'. - - main() - { - ... - dmalloc_shutdown(); - exit(0); - } - - -- Function: int dmalloc_verify ( char * PNT ) - This function verifies individual memory pointers that are suspect - of memory problems. To check the entire heap pass in a NULL or 0 - pointer. The routine returns DMALLOC_VERIFY_ERROR or - DMALLOC_VERIFY_NOERROR. - - _NOTE_: `dmalloc_verify()' can only check the heap with the - functions that have been enabled.

It is helpful in server or cgi-bin programs - where environmental variables cannot be used. *Note Debugging A - Server::. For instance, if debugging should never be enabled for a - program, a call to `dmalloc_debug(0)' as the first call in - `main()' will disable all the memory debugging from that point on. - - _NOTE_: you cannot add or remove certain flags such as signal - handlers since they are setup at initialization time only. - - _NOTE_: you can also use `dmalloc_debug_setup' below. - - - -- Function: unsigned-int dmalloc_debug_current ( void ) - This routine returns the current debug functionality value value. - This allows you to save a copy of the debug dmalloc settings to be - changed and then restored later. - - - -- Function: void dmalloc_debug_setup ( const char * OPTIONS_STR ) - This routine sets the global debugging functionality as an option - string.

They are used -by the library to indicate a detected problem. They can be caused by -the user (`ERROR_TOO_BIG') or can indicate an internal library problem -(`ERROR_SLOT_CORRUPT'). The `dmalloc' utility can give you the string -version of the error with the `-e' argument: - - $ dmalloc -e 60 - dmalloc: dmalloc_errno value '60' = - 'pointer is not on block boundary' - - Here are the error codes set by the library. They are non -contiguous on purpose because I add and delete codes all of the time -and there are sections for various error-code types. - -`1 (ERROR_NONE) no error' - No error. It is good coding practice to set the no-error code to - be non-0 value because it forces you to set it explicitly. - -`2 (INVALID_ERROR)' - Invalid error number. If the library outputs this error then your - dmalloc utility may be out of date with the library you linked - against. This will be returned with all error codes not listed - here. - -`10 (ERROR_BAD_SETUP) initialization and setup failed' - Bad setup value. This is currently unused but it is intended to - report on invalid setup configuration information. - -`11 (ERROR_IN_TWICE) malloc library has gone recursive' - Library went recursive. This usually indicates that you are not - using the threaded version of the library. Or if you are then you - are not using the `-o' "lock-on" option. *Note Using With - Threads::. - -`13 (ERROR_LOCK_NOT_CONFIG) thread locking has not been configured' - Thread locking has not been configured. This indicates that you - attempted to use the `-o' "lock-on" option without linking with - the thread version of the library. You should probably be using - `-ldmallocth' _not_ `-ldmalloc' when you are linking. Or you - should include `.../lib/libdmallocth.a' on your compilation line. - -`20 (ERROR_IS_NULL) pointer is null' - Pointer is null. The program passed a NULL (0L) pointer to `free' - and you have the `error-free-null' token enabled. - -`21 (ERROR_NOT_IN_HEAP) pointer is not pointing to heap data space' - Pointer is not pointing to heap data space. This means that the - program passed an out-of-bounds pointer to `free' or `realloc'. - This could be someone trying to work with a wild pointer or trying - to free a pointer from a different source than `malloc'. - -`22 (ERROR_NOT_FOUND) cannot locate pointer in heap' - Cannot locate pointer in heap. The user passed in a pointer which - the heap did not know about. Either this pointer was allocated by - some other mechanism (like `mmap' or `sbrk' directly) or it is a - random invalid pointer. - - In some rare circumstances, sometimes seen with shared libraries, - there can be two separate copies of the dmalloc library in a - program. Each one does not know about the pointers allocated by - the other. - -`23 (ERROR_IS_FOUND) found pointer the user was looking for' - This indicates that the pointer specified in the address part of - the environmental variable was discovered by the library. *Note - Environment Variable::. This error is useful so you can put a - breakpoint in a debugger to find where a particular address was - allocated. *Note Using With a Debugger::. - -`24 (ERROR_BAD_FILE) possibly bad .c filename pointer' - A possibly invalid filename was discovered in the dmalloc - administrative sections. This could indicate some corruption of - the internal tables. It also could mean that you have a source - file whose name is longer than 100 characters. See - `MAX_FILE_LENGTH' in the `settings.dist' file. - -`25 (ERROR_BAD_LINE) possibly bad .c file line-number' - A line-number was out-of-bounds in the dmalloc administrative - sections. This could indicate some corruption of the internal - tables. It also could mean that you have a source file containing - more than `30000' lines of code. See `MAX_LINE_NUMBER' in the - `settings.dist' file. - -`26 (ERROR_UNDER_FENCE) failed UNDER picket-fence magic-number check' - This indicates that a pointer had its lower bound picket-fence - magic number overwritten. If the `check-fence' token is enabled, - the library writes magic values above and below allocations to - protect against overflow. Most likely this is because a pointer - below it went past its allocate and wrote into the next pointer's - space. - -`27 (ERROR_OVER_FENCE) failed OVER picket-fence magic-number check' - This indicates that a pointer had its upper bound picket-fence - magic space overwritten. If the `check-fence' token is enabled, - the library writes magic values above and below allocations to - protect against overflow. Most likely this is because an array or - string allocation wrote past the end of the allocation. - - Check for improper usage of `strcat', `sprintf', `strcpy', and any - other functions which work with strings and do not protect - themselves by tracking the size of the string. These functions - should _always_ be replaced with: `strncat', `snprintf', - `strncpy', and others. - -`28 (ERROR_WOULD_OVERWRITE) use of pointer would exceed allocation' - This error is generated by the function pointer checking code - usually enabled with the `check-funcs' token. Dmalloc overloads a - number of string and memory copying functions and verifies that - the buffers (if allocated in the heap) would not be overwritten by - the function. - -`30 (ERROR_NOT_START_BLOCK) pointer is not to start of memory block' - This indicates that the user passed in a pointer to be freed or - reallocated that was not at the start of the allocation. You - would get this error, for example, if you allocate and get pointer - `X' but then try to free `X+1'. - -`40 (ERROR_BAD_SIZE) invalid allocation size' - This error indicates that a size value in the internal structures - of the library were corrupted. This could be a random pointer - problem, pointer overflow, or some other corruption. - -`41 (ERROR_TOO_BIG) largest maximum allocation size exceeded' - An allocation asked for memory larger than the configured maximum. - This is a user configured setting. See `LARGEST_ALLOCATION' in - the `settings.dist' file. It is used to protect against wild - allocation sizes. If you have super large allocation sizes then - you should tune the `LARGEST_ALLOCATION' value appropriately. - -`43 (ERROR_ALLOC_FAILED) could not grow heap by allocating memory' - The library could not allocate more heap space and the program has - run out of memory. This could indicate that you've overflowed - some system imposed limit. On many operation systems, the - `ulimit' call can tune system defaults. The library uses a lot - more memory compared to the system malloc library because it - stores a lot more information about the allocated pointers. - - _NOTE_: This also may be due to an inability of your operating - system to use the `mmap' system call to allocate memory. You may - need to force the `USE_MMAP' setting to be 0. Please use the - forums at URL `http://dmalloc.com/' to report issues with this. - -`45 (ERROR_OVER_LIMIT) over user specified allocation limit' - The library has allocated more memory than was specified in the - memory-limit environmental variable. *Note Environment Variable::. - -`60 (ERROR_NOT_ON_BLOCK) pointer is not on block boundary' - The user tried to free or realloc a pointer that was not pointing - to a block boundary. You would get this error, for example, if - you allocate and get pointer `X' but then try to free `X+1'. - -`61 (ERROR_ALREADY_FREE) tried to free previously freed pointer' - The user tried to free a pointer than has already been freed. - This is a very common mistake and can lead to serious problems. - It can be because a destructor is being called twice for some - reason. Although tracking down the specific source is highly - recommended, it is good to set pointers to NULL (0L) after you - free them as a rule. - -`67 (ERROR_FREE_OVERWRITTEN) free space has been overwritten' - If either the `free-blank' or `check-blank' tokens are enabled - then the library will overwrite memory when it is freed with the - "dmalloc-free" byte (hex 0xdf, octal 0337, decimal 223). If the - program writes into this space, then the library will detect the - write and trigger this error. This could indicate that the - program is using a pointer after it has been freed. - -`70 (ERROR_ADMIN_LIST) bad admin structure list' - An internal corruption in the library's administrative structures - has been detected. This could be a random pointer problem, pointer - overflow, or some other corruption. - -`72 (ERROR_ADDRESS_LIST) internal address list corruption' - An internal corruption in the library's administrative structures - has been detected. This could be a random pointer problem, pointer - overflow, or some other corruption. - -`73 (ERROR_SLOT_CORRUPT) internal memory slot corruption' - An internal corruption in the library's administrative structures - has been detected. This could be a random pointer problem, pointer - overflow, or some other corruption. - - - -File: dmalloc.info, Node: Disabling the Library, Next: Using With C++, Prev: Error Codes, Up: Programming - -3.7 How to Disable the library -============================== - -If you would like to disable the library's detailed checking features -during a particularly allocation intensive section of code, you can do -something like the following: - - unsigned int dmalloc_flags; - ... - /* turn off all debug flags and save a copy of old value */ - dmalloc_flags = dmalloc_debug(0); - - /* section of a lot of allocations */ - ... - /* end of section */ - - /* restore the dmalloc flag setting */ - dmalloc_debug(dmalloc_flags); - - When you are finished with the development and debugging sessions, -you may want to disable the dmalloc library and put in its place either -the system's memory-allocation routines, gnu-malloc, or maybe your own. -Attempts have been made to make this a reasonably painless process.

This library should be linked into -your C++ programs instead of `libdmalloc.a'. - - Dmalloc is not as good with C++ as C because the dynamic memory -routines in C++ are `new()' and `delete()' as opposed to `malloc()' and -`free()'. Since new and delete are usually not used as functions but -rather as `x = new type', there is no easy way for dmalloc to pass in -file and line information unfortunately. The `libdmallocxx.a' library -provides the file `dmallocc.cc' which effectively redirects `new' to -the more familiar `malloc' and `delete' to the more familiar `free'. - - _NOTE_: The author is not a C++ hacker so feedback in the form of -other hints and ideas for C++ users would be much appreciated. - - -File: dmalloc.info, Node: Using With a Debugger, Next: Using With Threads, Prev: Using With C++, Up: Programming - -3.9 Using Dmalloc With a Debugger -================================= - -Here are a number of possible scenarios for using the dmalloc library to -track down problems with your program. - - You should first enable a logfile filename and turn on a set of debug -features. You can use `dmalloc -l logfile low' to accomplish this. If -you are interested in having the error messages printed to your -terminal as well, enable the `print-messages' token by typing `dmalloc --p print-messages' afterwards. *Note Dmalloc Program::. - - Now you can enter your debugger (I use the _excellent_ GNU debugger -gdb), and put a break-point in `dmalloc_error()' which is the internal -error routine for the library. When your program is run, it will stop -there if a memory problem is detected. - - If you are using GDB, I would recommend adding the contents of -`dmalloc.gdb' in the `contrib' subdirectory to your `.gdbinit' file in -your home directory. This enables the `dmalloc' command which will -prompt you for the arguments to the dmalloc command and will set a -break point in `dmalloc_error()' automatically. - - If you are using shared libraries, you may want to execute the -following commands initially to load in dmalloc and other library -symbols: - - (gdb) sharedlibrary - (gdb) add-shared-symbol-files - -* Menu: - -* General Errors:: Diagnosing general problems with a debugger. -* Memory Leaks:: Tracking down non-freed memory. -* Fence-Post Overruns:: Diagnosing fence-post overwritten memory. -* Translate Return Addresses:: Convert ra return-addresses into a location. - - -File: dmalloc.info, Node: General Errors, Next: Memory Leaks, Prev: Using With a Debugger, Up: Using With a Debugger - -3.9.1 Diagnosing General Problems with a Debugger -------------------------------------------------- - -If your program stops at the `dmalloc_error()' routine then one of a -number of problems could be happening. Incorrect arguments could have -been passed to a malloc call: asking for negative number of bytes, -trying to realloc a non-heap pointer, etc.. There also could be a -problem with the system's allocations: you've run out of memory, some -other function in your program is using the heap allocation functions -`mmap' or `sbrk', etc.. However, it is most likely that some code that -has been executed was naughty. - - To get more information about the problem, first print via the -debugger the dmalloc_errno variable to get the library's internal error -code. You can suspend your debugger and run `dmalloc -e -value-returned-from-print' to get an English translation of the error. -A number of the error messages are designed to indicate specific -problems with the library administrative structures and may not be -user-friendly. - - If the problem was due to the arguments or system allocations then -the source of the problem has been found. However, if some code did -something wrong, you may have some more work to do to locate the actual -problem. The `check-heap' token should be enabled and the interval -setting disabled or set to a low value so that the library can find the -problem as close as possible to its source. The code that was execute -right before the library halted, can then be examined closely for -irregularities. *Note Debug Tokens::, *Note Dmalloc Program::. - - You may also want to put calls to `dmalloc_verify(0)' in your code -before the section which generated the error. This should locate the -problem faster by checking the library's structures at that point. -*Note Extensions::. - - -File: dmalloc.info, Node: Memory Leaks, Next: Fence-Post Overruns, Prev: General Errors, Up: Using With a Debugger - -3.9.2 Tracking Down Non-Freed Memory ------------------------------------- - -So you've run your program, examined the log-file and discovered (to -your horror) some un-freed memory. Memory leaks can become large -problems since even the smallest and most insignificant leak can starve -the program given the right circumstances. - - not freed: '0x45008' (12 bytes) from 'ra=0x1f8f4' - not freed: '0x45028' (12 bytes) from 'unknown' - not freed: '0x45048' (10 bytes) from 'argv.c:1077' - known memory not freed: 1 pointer, 10 bytes - unknown memory not freed: 2 pointers, 24 bytes - - Above you will see a sample of some non-freed memory messages from -the logfile. In the first line the `0x45008' is the pointer that was -not freed, the `12 bytes' is the size of the unfreed block, and the -`ra=0x1f8f4' or return-address shows where the allocation originated -from. *Note Translate Return Addresses::. - - The systems which cannot provide return-address information show -`unknown' instead, as in the 2nd line in the sample above. - - The `argv.c:1077' information from the 3rd line shows the file and -line number which allocated the memory which was not freed. This -information comes from the calls from C files which included -`dmalloc.h'. *Note Allocation Macros::. - - At the bottom of the sample it totals the memory for you and breaks -it down to known memory (those calls which supplied the file/line -information) and unknown (the rest). - - Often, you may allocate memory in via `strdup()' or another routine, -so the logfile listing where in the `strdup' routine the memory was -allocated does not help locate the true source of the memory leak - the -routine that called `strdup'. Without a mechanism to trace the calling -stack, there is no way for the library to see who the caller of the -caller (so to speak) was. - - However, there is a way to track down unfreed memory in this -circumstance. You need to compile the library with `STORE_SEEN_COUNT' -defined in `conf.h'. The library will then record how many times a -pointer has been allocated or freed. It will display the unfreed -memory as: - - not freed: '0x45008|s3' (12 bytes) from 'ra=0x1f8f4' - - The `STORE_SEEN_COUNT' option adds a `|s#' qualifier to the address. -This means that the address in question was seen `#' many times. In -the above example, the address `0x45008' was seen `3' times. The last -time it was allocated, it was not freed. - - How can a pointer be "seen" 3 times? Let say you `strdup' a string -of 12 characters and get address `0x45008' - this is #1 time the -pointer is seen. You then free the pointer (seen #2) but later -`strdup' another 12 character string and it gets the `0x45008' address -from the free list (seen #3). - - So to find out who is allocating this particular 12 bytes the 3rd -time, try `dmalloc -a 0x45008:3'. The library will stop the program the -third time it sees the `0x45008' address. You then enter a debugger -and put a break point at `dmalloc_error'. Run the program and when the -breakpoint is reached you can examine the stack frame to determine who -called `strdup' to allocate the pointer. - - To not bother with the `STORE_SEEN_COUNT' feature, you can also run -your program with the `never-reuse' token enabled. This token will -cause the library to never reuse memory that has been freed. Unique -addresses are always generated. This should be used with caution since -it may cause your program to run out of memory. - - -File: dmalloc.info, Node: Fence-Post Overruns, Next: Translate Return Addresses, Prev: Memory Leaks, Up: Using With a Debugger - -3.9.3 Diagnosing Fence-Post Overwritten Memory ----------------------------------------------- - -For a definition of fence-posts please see the "Features" section. -*Note Features::. - - To detect fence-post overruns, you need to enable the `check-fence' -token. *Note Debug Tokens::. This pads your allocations with some -extra bytes at the front and the end and watches the space to make sure -that they don't get overwritten. _NOTE:_ The library cannot detect if -this space gets read, only written. - - If you have encountered a fence-post memory error, the logfile -should be able to tell you the offending address. - - free: failed UNDER picket-fence magic-number checking: - pointer '0x1d008' from 'dmalloc_t.c:427' - Dump of proper fence-bottom bytes: '\e\253\300\300\e\253\300\300' - Dump of '0x1d008'-8: '\e\253\300\300WOW!\003\001pforger\023\001\123' - - The above sample shows that the pointer `0x1d008' has had its lower -fence-post area overwritten. This means that the code wrote below the -bottom of the address or above the address right below this one. In the -sample, the string that did it was `WOW!'. - - The library first shows you what the proper fence-post information -should look like, and then shows what the pointer's bad information was. -If it cannot print the character, it will display the value as `\ddd' -where ddd are three octal digits. - - By enabling the `check-heap' debugging token and assigning the -interval setting to a low number, you should be able to locate -approximately when this problem happened. *Note Debug Tokens::, *Note -Dmalloc Program::. - - -File: dmalloc.info, Node: Translate Return Addresses, Prev: Fence-Post Overruns, Up: Using With a Debugger - -3.9.4 Translating Return Addresses into Code Locations ------------------------------------------------------- - -The following gdb commands help you translate the return-addresses (ra=) -entries in the logfile into locations in your code.

It provides -support for mutex locking itself to protect against race conditions that -result in multiple simultaneous execution. One of the major problems is -that most thread libraries uses malloc themselves. Since all of -dmalloc's initialization happens when a call to malloc is made, we may -be attempting to initialize or lock the mutex while the thread library -is booting up. A very bad thing since thread libraries don't expect to -recurse. - - The solution to this problem is to have the library not initialize or -lock its mutex variable until after a certain number of allocation calls -have been completed. If the library does not wait before initializing -the locks, the thread library will probably core dump. If it waits too -long then it can't protect itself from multiple execution and it will -abort or other bad things might happen. You adjust the number of times -to wait at runtime with the `lock-on' option to the dmalloc program -(for example `dmalloc -o 20'). *Note Dmalloc Program::. Times values -between 5 and 30 are probably good although operating systems will vary -significantly. You know its too low if your program immediately core -dumps and too high if the dmalloc library says its gone recursive -although with low values, you might get either problem. - - An additional complexity is when we are initializing the lock before -mutex locking around the library. As mentioned, the initialization -itself may generate a malloc call causing the library to go recursive -and the pthread library to possibly core dump. With the THREAD_INIT_LOCK -setting defined in `settings.h', you can tune how many times before we -start locking to try and initialize the mutex lock. It defaults to 2 -which seems to work for me. If people need to have this runtime -configurable or would like to present an alternative default, please let -me know. - - So to use dmalloc with a threaded program, follow the following steps -carefully. - - 1. Follow the installation instructions on how to configure, make, - and install the library but make sure to add the - `--enable-threads' argument to configure. *Note Installation::. - - 2. Typing `make' should be enough to build the threaded versions of - the libraries including `libdmallocth.a'. - - 3. Link the dmalloc threaded library into your program. The dmalloc - library should probably be placed at or near the end of the library - list. - - 4. Enable the debugging options that you need by typing `dmalloc -l - logfile -i 100 low' (for example). `dmalloc --usage' will provide - verbose usage info for the dmalloc program. *Note Dmalloc - Program::. - - 5. Enable the "lock-on" option (for example `dmalloc -o 20'). As - explained above, you may have to try different values before - getting it right. Values between 5 and 30 are probably good. - - 6. If you get a dmalloc error #13 `thread locking has not been - configured' then you have not compiled you program with the - threaded version of dmalloc or there was a problem building it. - - 7. If everything works, you should be able to run your program, have - it not immediately crash, and the dmalloc library should not - complain about recursion. - - - If you have any specific questions or would like addition information -posted in this section, please let me know. Experienced thread -programmers only please. - - -File: dmalloc.info, Node: Using With Cygwin, Next: Debugging A Server, Prev: Using With Threads, Up: Programming - -3.11 Using the library with Cygwin environment. -=============================================== - -The Cygwin environment is a Linux-like environment for Windows. It -provides Linux look and feel as well as a programming environment. See -URL `http://www.cygwin.com/' for more details. - - Cygwin uses the `GetEnvironmentVariableA' function to read in -environmental variables instead of `getenv'. This functions are used -to get the value of the `DMALLOC_OPTIONS' variable which sets the -debugging options. *Note Environment Variable::. - - As of right now, dmalloc is not detecting the -`GetEnvironmentVariableA' function correctly so you may need to tune -the `conf.h' file to get it to work. See the sections on -`HAVE_GETENVIRONMENTVARIABLEA' and `GETENV_SAVE' settings. Feedback is -welcome here. - - If you still have problems reading in the environmental variables, -you can work around this issue. You can add some code into the `main' -function in your program to initialize the dmalloc flags yourself. -Here is a code sample: - - main(int argc, char **argv) - { - #ifdef DMALLOC - /* - * Get environ variable DMALLOC_OPTIONS and pass the settings string - * on to dmalloc_debug_setup to setup the dmalloc debugging flags. - */ - dmalloc_debug_setup(getenv("DMALLOC_OPTIONS")); - #endif - - /* rest of code in main starts here */ - ... - } - - The `#ifdef' is just a good idea. I means that when debugging with -dmalloc you need to compile your code with `-DDMALLOC'. When you are -done debugging you can remove the flag and the call to -`dmalloc_debug_setup' will be removed. - - Please let me know if there is a better way to do this. - - -File: dmalloc.info, Node: Debugging A Server, Next: Logfile Details, Prev: Using With Cygwin, Up: Programming - -3.12 Debugging Memory in a Server or Cgi-Bin Process -==================================================== - -There are some specified challenges when trying to debug allocations in -processes which do not startup, run, and then shutdown. Server -processes (often called daemons) are those that are started (often at -system boot time) and run perpetually. Other processes which are -difficult to debug are CGI programs which are spawned by web servers or -when you want to start debugging inside of a child process. - - 1. Build your server or cgi-bin program with the dmalloc library like - any other program. *Note Getting Started::. - - 2. Add code into your program to enable the library flags to perform - the memory checks that you require. Since these programs often do - not run from the command line, you cannot use the dmalloc utility - program and modify the process environment. *Note Dmalloc - Program::. The library provides a couple of functions to set the - debugging flags when a program is running. - - 3. To set the memory debugging flags, use the `dmalloc_debug_setup' - function which takes a string in the same format of the - `DMALLOC_OPTIONS' environmental variable. *Note Environment - Variable::. Use the dmalloc utility with the `-n' no-changes - argument to see the appropriate settings for the `DMALLOC_OPTIONS' - environmental variable. - - > dmalloc -n -l logfile high - Outputed: - DMALLOC_OPTIONS=debug=0x4f4ed03,log=logfile - export DMALLOC_OPTIONS - - So if you want to turn on `high' debugging and log to the file - `logfile' then you would copy the above `DMALLOC_OPTIONS' value - into a call to `dmalloc_debug_setup'. Notice that I have - surrounded the dmalloc code with an `#ifdef DMALLOC' so you'll - have to compile using the `-DDMALLOC' flag. - - main() - { - #ifdef DMALLOC - /* set the 'high' flags */ - dmalloc_debug_setup("debug=0x4f47d03,log=logfile"); - #endif - ... - } - - _Please note_ that the `dmalloc_debug_setup' function does not - know about `high', `low', or other debug tokens but needs the - actual flag values. - - 4. For earlier versions of the library (before 5.0.0) without - `dmalloc_debug_setup', the `dmalloc_debug' function is available - to set the flags directly, but it cannot adjust the logfile name - and the other environment settings. You can use the dmalloc - utility program to see what the numerical equivalent of the `high' - token. - - > dmalloc -n high - Outputed: - DMALLOC_OPTIONS=debug=0x4f4ed03 - export DMALLOC_OPTIONS - - You can then take the `0x4f4ed03' hexadecimal number and call - `dmalloc_debug' with that number. - - main() - { - #ifdef DMALLOC - /* set the 'high' flags */ - dmalloc_debug(0x4f4ed03); - #endif - ... - } - - 5. Even with the settings enabled, you may have problems getting the - logfile to be written if your program is running as `nobody' or - another user without permissions for security reasons. This is - especially true for cgi-bin programs. In this case you should - specify a full path to your malloc logfile in a world writable - directory (ex. - `dmalloc_debug_setup("debug=0x4f47d03,log=/var/tmp/malloc");'). - Watch for programs which change into other directories and which - may cause logfiles specified as relative or local paths to be - dropped in other locations. You may always want to use a full - path logfile. - - 6. Once you have your settings enabled and your log is being - generated, you may now want to check out how your process is doing - in terms of unfreed memory. Since it is not shutting down, the - automatic unfreed log entries are not being dropped to the - logfile. By using the `dmalloc_mark' and `dmalloc_log_changed' - functions, you can set a mark point at a certain place inside of - your program, and then later see whether there are any unfreed - pointers since the mark. - - main() - { - #ifdef DMALLOC - /* set the 'high' flags */ - dmalloc_debug_setup("debug=0x4f47d03,log=logfile"); - #endif - - while (1) { - /* accept a connection from a client */ - accept_connection(); - - while (1) { - #ifdef DMALLOC - unsigned long mark; - /* get the current dmalloc position */ - mark = dmalloc_mark() ; - #endif - /* process the connection */ - if (process_connection() != PROCESS_OK) { - break; - } - #ifdef DMALLOC - /* - * log unfreed pointers that have been added to - * the heap since mark - */ - dmalloc_log_changed(mark, - 1 /* log unfreed pointers */, - 0 /* do not log freed pointers */, - 1 /* log each pnt otherwise summary */); - #endif - } - /* close the connection with the client */ - close_connection(); - } - ... - } - - Usually you would set the mark after the initializations and before - each transaction is processed. Then for each transaction you can - use `dmalloc_log_changed' to show the unfreed memory. *Note - Extensions::. - - 7. You can also use the `dmalloc_log_stats' function to dump general - information about the heap. Also, remember that you can use the - `dmalloc_message' and `dmalloc_vmessage' routines to annotate the - dmalloc logfile with details to help you debug memory problems. - *Note Extensions::. - - - -File: dmalloc.info, Node: Logfile Details, Next: Other Hints, Prev: Debugging A Server, Up: Programming - -3.13 Explanation of the Logfile Output -====================================== - -Most of time you will be using the logfile output from library as the -sole information source for diagnosing problems in and getting -statistics for your program. - - 1098918225: 3: Dmalloc version 'Version 5.5.2' - 1098918225: 3: flags = 0x4f4e503, logfile '/tmp/dmalloc.log' - 1098918225: 3: interval = 500, addr = 0, seen # = 0, limit = 0 - 1098918225: 3: starting time = 1098918225 - 1098918225: 3: process pid = 32406 - 1098918226: 4: WARNING: tried to free(0) from foo.c:708' - 1098918228: 20: *** free: at 'unknown' pnt '0xed310080|s2': \ - size 12, alloced at 'bar.c:102' - 1098918230: 50: ERROR: heap_check: free space was overwritten (err 67) - 1098918230: 50: error details: checking free pointer - 1098918230: 50: pointer '0x291c5' from 'unknown' prev access 'foo.c:787' - - Here is a short example of some logfile information. Each of the -lines are prefixed by the time (in epoch seconds since 1/1/1970) and -the iteration or call count which is the number of times the library -has been called from malloc, free, verify, etc.. In the above example, -the first 5 log entries where written at epoch 1098918225 or `Wed Oct -27 19:03:45 2004 EST' and they were generated by the 3rd call to the -library. See the `settings.dist' file entries to tune what elements -appear on each line: LOG_TIME_NUMBER, LOG_ITERATION, LOG_PID, etc.. -You can convert the epoch seconds to a date from the command line with -the following perl code: `perl -e 'print localtime($ARGV[0])."\n";' -epoch-seconds-number' - - The first 5 lines of the sample logfile contain header information -for all logfiles. They show the version number and URL for the library -as well as all of the settings that the library is currently using. -These settings are tuned using the dmalloc utility program. *Note -Dmalloc Program::. The 5th line of is the process-id that generated -the logfile. - - The 6th line in the above example is what causes the logfile to be -opened and the header to be written. It is a warning that tells you -that you tried to free a 0L pointer at a certain location. You can -disable these warnings by setting `ALLOW_FREE_NULL_MESSAGE' to 0 in -`settings.dist'. - - Line 7 is an example of a transaction log that you get when you -enable the `log-trans' debug token. *Note Debug Tokens::. This line -shows that a call to free was made from an unknown location. It is -unknown because the file in question did not include `dmalloc.h' to get -file/line-number information. The call to free was freeing the pointer -address `0xed310080' which we have "seen" 2 times (s2). We saw the -pointer when it was allocated and then we are seeing it again when it -was freed. Because the library is reusing pointers (reclaiming freed -memory) the seen count helps to track how many times a pointer was -used. The last part of the line shows that the pointer to be freed was -allocated by `bar.c' line 102. - - Lines 8-10 is the next problem that the library caught and this one -is an error. It happened 5 seconds from the start of the log -(1098918230) and at the 50th call into the library. It shows that an -allocation that had been freed then was overwritten. This may imply -that someone tried to use memory after it was freed or that there was a -loose pointer reference. The last two lines give more details about -when the error was discovered, the address of the offending pointer, -and when the pointer was previous accessed, in this case freed. To -discover where this problem is happening, you can use a debugger. -*Note Using With a Debugger::. - - -File: dmalloc.info, Node: Other Hints, Prev: Logfile Details, Up: Programming - -3.14 Various Other Hints That May Help -====================================== - -One of the problems that is often seen is that a program crashes in the -`libc' memory code and you suspect a heap memory problem but both -dmalloc and maybe valgrind don't show any problems. One of the big -problems with debugging is that it is very difficult to do it without -effecting how the program is run. Sometimes errors are due to subtle -race conditions that are only seen when the program is running at full -speed - not slowed down by debugging code. - - This is especially true with threaded code which is often heavily -affected when used with dmalloc and valgrind. Older versions of -valgrid (maybe current) forced all threads into a single virtual system -by design, which often masks reentrance bugs. - - One way to work through these issues is to run with the library with -very few debugging flags enabled. Many memory problems are fence-post -areas so start with dmalloc checking just the fence post and error -logging enabled: - - dmalloc -d 0 -l dmalloc.log -p log-stats -p log-non-free -p check-fence -p check-funcs - - This enabled a small number of checks and should cause your program -to run at close to full speed. The library has never been optimized for -speed so some performance penalties will be felt. - - -File: dmalloc.info, Node: Dmalloc Program, Next: Source Code, Prev: Programming, Up: Top - -4 Dmalloc Utility Program -************************* - -The dmalloc program is designed to assist in the setting of the -environment variable `DMALLOC_OPTIONS'. *Note Environment Variable::. -It is designed to print the shell commands necessary to make the -appropriate changes to the environment.

Unfortunately, it cannot make -the changes on its own so the output from dmalloc should be sent -through the `eval' shell command which will do the commands. - - With shells that have aliasing or macro capabilities: csh, bash, ksh, -tcsh, zsh, etc., setting up an alias to dmalloc to do the eval call is -recommended. Bash, ksh, and zsh users should add the following to their -`.bashrc', `.profile', or `.zshrc' file respectively (notice the `-b' -option for bourne shell output): - - function dmalloc { eval `command dmalloc -b $*`; } - - If your shell does not support the `command' function then try: - - function dmalloc { eval `\dmalloc -b $*`; } - or - function dmalloc { eval `/usr/local/bin/dmalloc -b $*`; } - - If you are _still_ using csh or tcsh, you should add the following -to your `.cshrc' file (notice the `-C' option for c-shell output): - - alias dmalloc 'eval `\dmalloc -C \!*`' - - This allows the user to execute the dmalloc command as `dmalloc -arguments'. - - Users of versions of the Bourne shell (usually known as /bin/sh) that -don't have command functions will need to send the output to a temporary -file and the read it back in with the "." command: - - $ dmalloc -b arguments ... > /tmp/out - $ . /tmp/out - - By the way, if you are looking for a shell, I heartily recommend -trying out zsh. It is a bourne shell written from scratch with much -the same features as tcsh without the csh crap. - - _NOTE_: After you add the alias to the file you need to log out and -log back in to have it take effect, or you can execute the above -appropriate command on the command line. If you enter `dmalloc -runtime' and see any output with DMALLOC_OPTIONS in it then the alias -did not work. - - -File: dmalloc.info, Node: Utility Usage, Next: Environment Variable, Prev: Shell Alias, Up: Dmalloc Program - -4.2 How to Use the Dmalloc Program -================================== - -The most basic usage for the program is `dmalloc [-bC] tag'. The `-b' -or `-C' (either but not both flags used at a time) are for generating -Bourne or C shell type commands respectively. dmalloc will try and use -the `SHELL' environment variable to determine whether bourne or C shell -commands should be generated but you may want to explicitly specify the -correct flag. - - The `tag' argument to dmalloc should match a line from the user's -runtime configuration file or should be one of the built-in tags. -*Note RC File::. If no tag is specified and no other option-commands -used, dmalloc will display the current settings of the environment -variable. It is useful to specify one of the verbose options when doing -this. - - To find out the usage for the debug malloc program try `dmalloc ---usage-long'. The standardized usage message that will be displayed is -one of the many features of the argv library included with this package. - - It is available on the web at URL `http://256.com/sources/argv/'. -See the documentation there for more information. - - Here is a detailed list of the flags that can passed to dmalloc: - -`-a address' - Set the `addr' part of the `DMALLOC_OPTIONS' variable to address - (or alternatively address:number). - -`-b' - Output Bourne shell type commands. Usually handled automagically. - -`-C' - Output C shell type commands. Usually handled automagically. - -`-c' - Clear/unset all of the settings not specified with other - arguments. You can do this automatically when you set to a new - tag with the `-r' option. - - _NOTE_: clear will never unset the `debug' setting. Use `-d 0' or - a tag to `none' to achieve this. - -`-d bitmask' - Set the `debug' part of the `DMALLOC_OPTIONS' env variable to the - bitmask value which should be in hex. This is overridden (and - unnecessary) if a tag is specified. - -`-D' - List all of the debug-tokens. Useful for finding a token to be - used with the `-p' or `-m' options. Use with `-v' or `-V' verbose - options. - -`-e errno' - Print the dmalloc error string that corresponds to the error number - errno. - -`-f filename' - Use this configuration file instead of the RC file - `$HOME/.dmallocrc'. - -`-g' - Output gdb type commands for using inside of the gdb debugger. - -`-h (or --help)' - Output a help message for the utility. - -`-i number' - Set the checking interval to number. If the `check-heap' token is - enabled, this causes the library to only check the heap every Nth - time which can _significantly_ increase the running speed of your - program. If a problem is found, however, this limits your ability - to determine when the problem occurred. Try values of 50 or 100 - initially. - -`-k' - Do not reset all of the settings when a tag is specified. This - specifically overrides the `-r' option and is provided here to - override `-r' if it has been added to the dmalloc alias. - -`-l filename' - Write the debugging output and other log-file information to the - filename. Filename can include some of the following patterns - which get expanded into strings: - - `%h' - Gets expanded into the hostname if the `gethostname()' - function is available. - - `%i' - Gets expanded into the thread-id if the library has been - configure to be used with threads. *Note Using With - Threads::. See the end of the `settings.dist' file for - settings which return the thread-id and convert it into a - string. - - `%p' - Gets expanded into the process-id if the `getpid()' function - is available. - - `%t' - Gets expanded into the time value in seconds if the `time()' - function is available. - - `%u' - Gets expanded into the user-id number if the `getuid()' - function is available. - - - Some examples: - - # logfile produced with pid extension: - # logfile.8412 or logfile.31451 - dmalloc -l logfile.%p - - # hostname and time extensions: - # dmalloc-box1.foo.com-1055213240 - dmalloc -l dmalloc-%h-%t - - # if threads enabled, have thread-id extension: log.thread32 - dmalloc -l log.thread%i - -`-L' - Write the debug-value into the environment not in hex but by - individual debug-tokens in long form. - -`-m token(s)' - Remove (minus) the debug capabilities of token(s) from the current - debug setting or from the selected tag (or `-d' value). Multiple - `-m' options can be specified. - -`-M limit' - Set the memory allocation limit which will abort the program if the - total memory allocations exceed this number of bytes. The limit - can be a number with a k, m, or g at the end to indicate kilobyte, - megabyte, and gigabyte respectively. Ex: 100k, 200m, 1g. If the - limit is exceeded, this will generate an `ERROR_OVER_LIMIT' error. - *Note Error Codes::. - -`-n' - Without changing the environment, output the commands resulting - from the supplied options. - -`-o times' - Set the "lock-on" period which dictates to the threaded version of - the library to not initialize or lock the mutex lock around the - library until after a certain number of allocation calls have been - made. Some number between 2 and 30 is probably good. See the - "Using With Threads" section for more information about the - operation of the library with threads. *Note Using With Threads::. - -`-p token(s)' - Add (plus) the debug capabilities of token(s) to the current debug - setting or to the selected tag (or `-d' value). Multiple `-p' - options can be specified. - -`-r' - Remove (unset) all settings when using a tag. This is useful when - you are returning to a standard development tag and want the - logfile, address, and interval settings to be cleared - automatically. If you want this behavior by default, this can be - put into the dmalloc alias. - -`-R' - Output rc shell type commands. This is not for the runtime - configuration file but for the rc shell program. - -`-s file:line' - Set the `start' part of the `DMALLOC_OPTIONS' env variable to a - file-name and line-number location in the source where the library - should begin more extensive heap checking. The file and line - numbers for heap transactions must be working for this option to - be obeyed. This is used if you are trying to locate a problem and - you want the extensive checking to not happen initially because - it's too slow. - -`-S number' - Set the `start' part of the `DMALLOC_OPTIONS' env variable to an - dmalloc mark number. The library will begin more extensive heap - checking after this number of memory transactions. If you - `LOG_ITERATION' enabled in your `settings.h' file then the entries - in the log file will be prepended with the number of memory - transactions that the library has handled so far. This number can - be used to delay the start of the fine grained heap checking which - can be very slow. - -`--start-size size' - Set the `start' part of the `DMALLOC_OPTIONS' env variable to a - number of bytes. The library will begin more extensive heap - checking after this amount of memory has been allocated by the - library. This allows you to start the slow and detailed checking - of the library later in the program execution. You can use - patterns like 250m, 1g, or 102k to mean 250 megabytes, 1 gigabyte, - and 102 kilobytes respectively. - -`-t' - List all of the tags in the rc-file. Use with `-v' or `-V' - verbose options. - -`-u (or --usage)' - Output the usage information for the utility. - -`-v' - Give verbose output. Especially useful when dumping current - settings or listing all of the tags. - -`-V' - Give very verbose output for outputting even more details about - settings. - -`--version' - Output the version string for the utility. _Please note_ that the - version of the library that is installed or has been linked into - your application may be different from the utility version. - - - If no arguments are specified, dmalloc dumps out the current settings -that you have for the environment variable. For example: - - Debug-Flags '0x40005c7' (runtime) - Address 0x1f008, count = 3 - Interval 100 - Logpath 'malloc' - Start-File not-set - - With a -v option and no arguments, dmalloc dumps out the current -settings in a verbose manner. For example: - - Debug-Flags '0x40005c7' (runtime) - log-stats, log-non-free, log-bad-space, check-fence, catch-null - Address 0x1f008, count = 10 - Interval 100 - Logpath 'malloc' - Start-File not-set - - Here are some examples of dmalloc usage: - - # start tough debugging, check the heap every 100 times, - # send the log information to file 'logfile' - dmalloc high -i 100 -l logfile - - # find out what error code 20 is (from the logfile) - dmalloc -e 20 - - # cause the library to halt itself when it sees the address 0x34238 - # for the 6th time. - dmalloc -a 0x34238:6 - - # send the log information to file 'logfile' with the time in seconds - # as an extension. - dmalloc -l logfile.%t - - # return to the normal 'runtime' settings and clear out all - # other settings - dmalloc -c runtime - - # enable basic 'low' settings plus (-p) the logging of - # transactions (log-trans) to file 'logfile' - dmalloc low -p log-trans -l logfile - - # print out the current settings with Very-verbose output - dmalloc -V - - # list the available debug malloc tokens with Very-verbose output - dmalloc -DV - - # list the available tags from the rc file with verbose output - dmalloc -tv - - -File: dmalloc.info, Node: Environment Variable, Next: Debug Tokens, Prev: Utility Usage, Up: Dmalloc Program - -4.3 Environment Variable Name and Features -========================================== - -An "environment variable" is a variable that is part of the user's -working environment and is shared by all the programs. The -`DMALLOC_OPTIONS' variable is used by the dmalloc library to enable or -disable the memory debugging features, at runtime. _NOTE:_ you can -also use the `dmalloc_debug_setup' function to set the option string. -It can be set either by hand or with the help of the dmalloc program. -*Note Dmalloc Program::. - - To set it by hand, Bourne shell (sh, bash, ksh, or zsh) users should -use: - - DMALLOC_OPTIONS=value - export DMALLOC_OPTIONS - - C shell (csh or tcsh) users need to invoke: - - setenv DMALLOC_OPTIONS value - - The value in the above examples is a comma separated list of tokens -each having a corresponding value. The tokens are described below: - -`debug' - This should be set to a value in hexadecimal which corresponds to - the functionality token values added together. *Note Debug - Tokens::. For instance, if the user wanted to enable the logging - of memory transactions (value `0x008') and wanted to check - fence-post memory (value `0x400') then `debug' should be set to - `0x408' (`0x008' + `0x400'). - - _NOTE_: You don't have to worry about remembering all the hex - values of the tokens because the dmalloc program automates the - setting of this variable especially. - - _NOTE_: You can also specify the debug tokens directly, separated - by commas. *Note Debug Tokens::. If `debug' and the tokens are - both used, the token values will be added to the debug value. - -`lockon' - Set this to a number which is the "lock-on" period. This dictates - to the threaded version of the library to not initialize or lock - the mutex lock around the library until after a certain number of - allocation calls have been made. See the "Using With Threads" - section for more information about the operation of the library - with threads. *Note Using With Threads::. - -`log' - Set this to a filename so that if `debug' has logging enabled, the - library can log transactions, administration information, and/or - errors to the file so memory problems and usage can be tracked. - - To get different logfiles for different processes, you can assign - `log' to a string with `%d' in it (for instance `logfile.%d'). - This will be replaced with the pid of the running process (for - instance `logfile.2451'). - - _WARNING_: it is easy to core dump any program with dmalloc, if - you send in a format with arguments other than the one `%d'. - -`addr' - When this is set to a hex address (taken from the dmalloc log-file - for instance) dmalloc will abort when it finds itself either - allocating or freeing that address. - - The address can also have an `:number' argument. For instance, if - it was set it to `0x3e45:10', the library will kill itself the 10th - time it sees address `0x3e45'. By setting the number argument to - 0, the program will never stop when it sees the address. This is - useful for logging all activity on the address and makes it easier - to track down specific addresses not being freed. - - This works well in conjunction with the `STORE_SEEN_COUNT' option. - *Note Memory Leaks::. - - _NOTE_: dmalloc will also log all activity on this address along - with a count. - -`inter' - By setting this to a number X, dmalloc will only check the heap - every X times. This means a number of debugging features can be - enabled while still running the program within a finite amount of - time. - - A setting of `100' works well with reasonably memory intensive - programs. This of course means that the library will not catch - errors exactly when they happen but possibly 100 library calls - later. - -`start' - Set this to a number X and dmalloc will begin checking the heap - after X times. This means the intensive debugging can be started - after a certain point in a program. - - `start' also has the format `file:line'. For instance, if it is - set to `dmalloc_t.c:126' dmalloc will start checking the heap - after it sees a dmalloc call from the `dmalloc_t.c' file, line - number 126. If you use `dmalloc_t.c:0', with a 0 line number, then - dmalloc will start checking the heap after it sees a call from - anywhere in the `dmalloc_t.c' file. - - This allows the intensive debugging to be started after a certain - routine or file has been reached in the program. - - Some examples are: - - # turn on transaction and stats logging and set - # 'logfile' as the log-file - setenv DMALLOC_OPTIONS log-trans,log-stats,log=logfile - - # enable debug flags 0x1f as well as heap-checking and - # set the interval to be 100 - setenv DMALLOC_OPTIONS debug=0x1f,check-heap,inter=100 - - # enable 'logfile' as the log-file, watch for - # address '0x1234', and start checking when we see - # file.c line 123 - setenv DMALLOC_OPTIONS log=logfile,addr=0x1234,start=file.c:123 - - -File: dmalloc.info, Node: Debug Tokens, Next: RC File, Prev: Environment Variable, Up: Dmalloc Program - -4.4 Description of the Debugging Tokens -======================================= - -The below tokens and their corresponding descriptions are for the -setting of the debug library setting in the environment variable. -*Note Environment Variable::. They should be specified in the user's -`.dmallocrc' file. *Note RC File::. - - Each token, when specified, enables a specific debugging feature. -For instance, if you have the `log-stats' token enabled, the library -will log general statistics to the logfile. - - To get this information on the fly, use `dmalloc -DV'. This will -print out the Debug tokens in Very-verbose mode. *Note Dmalloc -Program::. - -`none' - No debugging functionality - -`log-stats' - Log general statistics when dmalloc_shutdown or dmalloc_log_stats - is called. - -`log-non-free' - Log non-freed memory pointers when dmalloc_shutdown or - dmalloc_log_unfreed is called. - -`log-known' - Log only known memory pointers that have not been freed. Pointers - which do not have file/line or return-address information will not - be logged. - -`log-trans' - Log general memory transactions (quite verbose). - -`log-admin' - Log administrative information (quite verbose). - -`log-bad-space' - Log actual bytes in and around bad pointers. - -`log-nonfree-space' - Log actual bytes in non-freed pointers. - -`log-elapsed-time' - Log elapsed-time for allocated pointers (see `conf.h'). - -`log-current-time' - Log current-time for allocated pointers (see `conf.h'). - -`check-fence' - Check fence-post memory areas. - -`check-heap' - Verify heap administrative structure. - -`check-blank' - Check to see if space that was blanked when a pointer was - allocated or when it was freed has been overwritten. If this is - enabled then it will enable `free-blank' and `alloc-blank' - automatically. - -`check-funcs' - Check the arguments of some functions (mostly string operations) - looking for bad pointers. - -`check-shutdown' - Check all of the pointers in the heap when the program exits. - -`catch-signals' - Shutdown the library automatically on SIGHUP, SIGINT, or SIGTERM. - This will cause the library to dump its statistics (if requested) - when you press control-c on the program (for example). - -`realloc-copy' - Always copy data to a new pointer when realloc. - -`free-blank' - Write special "dmalloc-free" byte (hexadecimal `0xdf', octal - `0337', decimal `223') into space when it is freed. You can set - this to be something else in the `settings.dist' file. This - ensures that your program is not using memory after it has been - freed. You can check to see if areas have been improperly - overwritten with the `check-blank' token. If the free space has - been overwritten, then `ERROR_FREE_OVERWRITTEN' is triggered. - *Note Error Codes::. - -`error-abort' - Abort the program (and dump core) on errors. See `error-dump' - below. *Note Dumping Core::. - -`alloc-blank' - Write special "dmalloc-alloc" byte (hexadecimal `0xda', octal - `0332', decimal `218') into space when it is allocated. You can - set this to be something else in the `settings.dist' file. If you - are not using `calloc' this will overwrite the user space with the - special bytes ensuring that your program is initializing its - dynamic memory appropriately. Also, if you ask for 35 bytes and - the library has to give you a block of 64 because of rounding - issues, it will overwrite the extra memory with the special byte. - You can then check to see if the extra areas have been improperly - overwritten by enabling the `check-blank' token. - -`print-messages' - Log any errors and messages to the screen via standard-error. - -`catch-null' - Abort the program immediately if the library fails to get more heap - space from the heap allocation routine `mmap' or `sbrk'. - -`never-reuse' - Have the heap never use space that has been used before and freed. - *Note Memory Leaks::. _WARNING_: This should be used with caution - since you may run out of heap space. - -`error-dump' - Dump core on error and then continue. Later core dumps overwrite - earlier ones if the program encounters more than one error. See - `error-abort' above. *Note Dumping Core::. - - _NOTE_: This will only work if your system supports the `fork' - system call and the configuration utility was able to fork without - going recursive. - -`error-free-null' - By default the library will not generate an error when a program - tries to free a NULL pointer. By enabling this token, you can - change this behavior so an error is reported. See also the - ALLOW_FREE_NULL and ALLOW_FREE_NULL_MESSAGE settings in the - `settings.h' file to change the default behavior. - - - -File: dmalloc.info, Node: RC File, Prev: Debug Tokens, Up: Dmalloc Program - -4.5 Format of the Runtime Configuration File -============================================ - -By using a "RC File" (or runtime configuration file) you can alias tags -to combinations of debug tokens. *Note Debug Tokens::. - - _NOTE_: For beginning users, the dmalloc program has a couple of -tags built into it so it is not necessary for you to setup a RC file: - -`runtime' - Enables basic runtime tests including fence-post checking, null - handling, and logging of any errors. - -`low' - Runtime settings plus minimal checking of heap structures and - overwriting of allocated and freed space. - -`medium' - Low settings plus checking of all heap structures on each memory - call, always relocates block on realloc, and aborts on errors. - You may want to use `-i' option to the dmalloc utility. *Note - Dmalloc Program::. - -`high' - Medium settings plus checking of overwritten freed and allocated - memory and checking of arguments to a number of common functions. - You may want to use `-i' option to the dmalloc utility. *Note - Dmalloc Program::. - - - For expert users, a sample `dmallocrc' file has been provided but -you are encouraged to roll your own combinations. The name of default -rc-file is `$HOME/.dmallocrc'. The `$HOME' environment variable should -be set by the system to point to your home-directory. - - The file should contain lines in the general form of: - - tag token1, token2, ... - - `tag' is to be matched with the tag argument passed to the dmalloc -program, while `token1, token2, ...' are debug capability tokens. -*Note Dmalloc Program::, *Note Debug Tokens::. - - A line can be finished with a `\' meaning it continues onto the next -line. Lines beginning with `#' are treated as comments and are ignored -along with empty lines. - - Here is an example of a `.dmallocrc' file: - - # - # Dmalloc runtime configuration file for the debug malloc library - # - - # no debugging - none none - - # basic debugging - debug1 log-stats, log-non-free, check-fence - - # more logging and some heap checking - debug2 log-stats, log-non-free, log-trans, \ - check-fence, check-heap, error-abort - - # good utilities - debug3 log-stats, log-non-free, log-trans, \ - log-admin, check-fence, check-heap, realloc-copy, \ - free-blank, error-abort - - ... - - For example, with the above file installed, you can type `dmalloc -debug1' after setting up your shell alias. *Note Dmalloc Program::. -This enables the logging of statistics, the logging of non-freed memory, -and the checking of fence-post memory areas. - - Enter `dmalloc none' to disable all memory debugging features. - - -File: dmalloc.info, Node: Source Code, Next: Troubleshooting, Prev: Dmalloc Program, Up: Top - -5 Information on the Source Code -******************************** - -* Menu: - -* Definitions:: Definition of terms and other information. -* Compatibility:: General compatibility concerns. -* Portability:: Issues important for porting the library. - - -File: dmalloc.info, Node: Definitions, Next: Compatibility, Prev: Source Code, Up: Source Code - -5.1 Definition of Terms and other Information -============================================= - -Here are a couple definitions and other information for those interested -in "picking the brain" of the library. The code is a little ugly here -and there and it conforms to the Gray-Watson handbook of coding -standards only. - -"bblock" - basic block containing 2 ^ BASIC_BLOCK bytes of info - -"bblock_adm" - administration for a set of basic blocks - -"dblock" - divided block containing some base 2 number of blocks smaller than - a basic block. - -"dblock_adm" - administration for a set of divided blocks - -"chunk" - some anonymous amount of memory - - For more information about administration structures, see the code -and comments from `chunk_loc.h'. - - -File: dmalloc.info, Node: Compatibility, Next: Portability, Prev: Definitions, Up: Source Code - -5.2 General Compatibility Concerns -================================== - - * Realloc() backwards compatibility with being able to realloc from - the last freed block is _not_ supported. The author is interested - to know who is using this (cough, cough) feature and for what - reason. - - * Realloc() of a NULL pointer is supported in which case the library - will just make a call to malloc(). This can be disabled with the - help of the `ALLOW_REALLOC_NULL' manual compilation option in the - `settings.h' file to adjust the library's default behavior. - - * Some systems allow free(0) to not be an error for some reason. - Since 0 is not a valid address returned by the malloc call, it is - debatable that this should be allowed. See `settings.h' for the - `ALLOW_FREE_NULL' manual compilation option to adjust the - library's default behavior. - - * Aside from possibly being slower than the system's memory - allocation functions, the library should be fully compatible with - the standard memory routines. If this is _not_ the case, please - bring this to my attention. - - -File: dmalloc.info, Node: Portability, Prev: Compatibility, Up: Source Code - -5.3 Issues Important for Porting the Library -============================================ - -General portability issues center around: - - * mmap, sbrk, or compatible function usages. The library does - support a preallocated memory chunk heap. See the - `INTERNAL_MEMORY_SPACE' define in the `settings.dist' file. - - * The locating of the caller's address from the dmalloc functions. - This is useful in locating problems from dmalloc functions called - from C files which did not include `dmalloc.h': C library calls for - instance. - - See `return.h' for the available architecture/compiler - combinations. You may want to examine the assembly code from gcc - (GNUs superior c-compiler) version 2+ being run on the following - code. It should give you a good start on building a hack for your - box. - - static char * x; - - a() - { - x = __builtin_return_address(0); - } - - main() - { - a(); - } - - - -------------------------------------------------------------------------------- - -6 Some Solutions to Common Problems -*********************************** - -This section provides some answers to some common problems and -questions. Please send me mail with any additions to this list - -either problems you are still having or tips that you would like to -pass on. - - When diagnosing a problem, if possible, always make sure you are -running the most up to date version of Dmalloc available from the home -page at URL `http://dmalloc.com/'. Problems are often fixed and a new -release can be published before people encounter them. - -`Why does my program run so slow?' - This library has never been (and maybe never will be) optimized for - space nor speed. Some of its features make it unable to use some - of the organizational methods of other more efficient heap - libraries. - - If you have the `check-heap' token enabled, your program might run - slow or seem to hang. This is because by default, the library - will run a full check of the heap with every memory allocation or - free. You can have the library check itself less frequently by - using the `-i' option to the dmalloc utility. *Note Dmalloc - Program::. If you are using the `high' token and you need your - program to run faster, try the `medium' or `low' tokens which - don't check as many heap features and so run faster although they - will not catch as many problems. *Note RC File::. - -`Why was a log-file not produced after I ran my program?' - This could be caused by a number of different problems. - - 1. Are you sure you followed all of the items in the "Getting - Started" section? Please review them if there is any doubt. - *Note Getting Started::. - - 2. Use the `env' or `printenv' commands to make sure that the - `DMALLOC_OPTIONS' variable is set in your exported - environment. *Note Environment Variable::. - - 3. Make sure that your program has been compiled correctly with - the dmalloc library. The `ident' program should show chunk.c - and other dmalloc files compiled into your program. You can - also do `strings -a your-program | grep chunk.c' and look for - something like `$Id: chunk.c,v 1.152 1999/08/25 12:37:01 gray - Exp $' with different versions and date information. If this - doesn't show up then chances are dmalloc was not linked into - your program. - - 4. If your program changes its working directory, it may write - the dmalloc log-file somewhere else in the filesystem. You - will need to check both where the program was started and to - where it might change directory. - - 5. The logfile is only produced when `dmalloc_shutdown()' is - called. By default it will be called when `exit()' gets - called. If you are running your program and press - `Control-C' under Unix the program will stop immediately and - `dmalloc_shutdown()' will not get called. You can either - setup a signal handler for `SIGINTR' and call exit yourself, - or you can enable the `catch-signals' token. *Note Debug - Tokens::. - - 6. If your program is segfaulting or otherwise crashing when it - exits, the `exit()' routine may not being called. You will - have to resolve these issues so the dmalloc library can - gracefully exit and write its log file. - - 7. You may want to call `dmalloc_log_stats()' and - `dmalloc_log_unfreed()' (or `dmalloc_log_changed()') directly - to have the library write its log file. Some system modules - may not have shutdown if you call this before `exit()' so - extra unfreed memory may be reported. - - -`I don't see any information about my non-freed (leaked) memory?' - The library will not (by default) report on "unknown" non-freed - memory. Unknown means memory that does not have associated file - and line information. - - This will be necessary if you are _not_ including `dmalloc.h' in - all of your C files or if you are interested in tracking leaks in - system functions. - -`Dmalloc is returning the error "malloc library has gone recursive"' - This most likely indicates that you are using the Dmalloc library - within a threaded application and two threads are trying to use - the dmalloc library at once. Please see the section of the manual - about threads for more information about properly configuring the - library. *Note Using With Threads::. - - If you are not using threads, then your program could have caught a - signal while within Dmalloc, which then in turn called a memory - allocation routine. It is unwise to allocate memory on the heap - in most signal handlers. Lastly, some functions called by the - library may call memory routines that it does not anticipate. If - you think this the case, please report the problem and include a - stack trace, operating system version/type, and the version of - Dmalloc you are using. - - - -File: dmalloc.info, Node: Index of Concepts, Prev: Troubleshooting, Up: Top - -Index of Concepts -***************** - -[index] -* Menu: - -* %h: Utility Usage.

Grumble. - * It basically replaces the strtok function because it is reentrant. - * This tokenizes a string by returning the next token in a string and - * punching a \0 on the first delimiter character past the token. The - * difference from strtok is that you pass in the address of a string - * pointer which will be shifted allong the buffer being processed. - * With strtok you passed in a 0L for subsequant calls. Yeach. - * - * This will count the true number of delimiter characters in the string - * and will return an empty token (one with \0 in the zeroth position) - * if there are two delimiter characters in a row. - * - * Consider the following example: - * - * char *tok, *str_p = "1,2,3, hello there "; - * - * while (1) { tok = strsep(&str_p, " ,"); if (tok == 0L) { break; } } - * - * strsep will return as tokens: "1", "2", "3", "", "hello", "there", "". - * Notice the two empty "" tokens where there were two delimiter - * characters in a row ", " and at the end of the string where there - * was an extra delimiter character. If you want to ignore these - * tokens then add a test to see if the first character of the token - * is \0. - * - * RETURNS: - * - * Success - Pointer to the next delimited token in the string. - * - * Failure - 0L if there are no more tokens. - * - * ARGUMENTS: - * - * string_p - Pointer to a string pointer which will be searched for - * delimiters. \0's will be added to this buffer. - * - * delim - List of delimiter characters which separate our tokens.

Debug Malloc Library

- - - -

The debug memory allocation or dmalloc library has been designed -as a drop in replacement for the system's malloc, realloc, -calloc, free and other memory management routines while -providing powerful debugging facilities configurable at runtime. These -facilities include such things as memory-leak tracking, fence-post write -detection, file/line number reporting, and general logging of -statistics. -

-

The library is reasonably portable having been run successfully on at -least the following operating systems: AIX, DGUX, Free/Net/OpenBSD, -GNU/Hurd, HPUX, Irix, Linux, Mac OSX, NeXT, OSF/DUX, SCO, Solaris, -Ultrix, Unixware, MS Windows, and Unicos on a Cray T3E. It also -provides support for the debugging of threaded programs. See section Using the Library with a Thread Package. -

-

The package includes the library, configuration scripts, debug utility -application, test program, and documentation. Online documentation as -well as the full source is available at URL http://dmalloc.com/. -Details on the library's mailing list are available there as well. -

-

Please use the forums at URL http://dmalloc.com/ to discuss any -problems or to request features. If you are still having problems, -the author can be reached via his home page at URL -http://256.com/gray/ with questions or feedback. Please -include the version number of the library that you are using, your -machine and operating system types, and the value of the -DMALLOC_OPTIONS environment variable. -

2.1 How to Install the Library

- - -

To configure, compile, and install the library, follow these steps -carefully. -

-
    -
  1. Make sure you have downloaded the latest version of the library -available from the home page at URL http://dmalloc.com/. - -
  2. The release files have a `.tgz' file extension which means -that they are a tar'd gzip'd directory of files. You will need to -ungzip and then untar the release file into your source work -directory. You may have to rename the file to `.tar.gz' to get -some old zip programs to handle the file correctly. - - - -
  3. You may want to edit or at least review the settings in -`settings.dist' to tune specific features of the library. The -`configure' script will copy this file to `settings.h' which -is where you should be adding per-architecture settings. - - - - - - - -
  4. Type sh ./configure to configure the library. You may want -to first examine the `config.help' file for some information about -configure. You may want to use the --disable-cxx option if you do -not want the Makefile to build the C++ version of dmalloc. You may want -to use the --enable-threads option to build the threaded version -of dmalloc. You may want to use the --enable-shlib option to -build the shared versions of the dmalloc libraries. sh ./configure ---help lists the available options to configure. Configure should -generate the `Makefile' and configuration files automatically. - -
  5. You may want to examine the `Makefile' and `conf.h' files -created by configure to make sure it did its job correctly. - - - -
  6. You might want to tune the settings in `settings.h' file to -tune the library to the local architecture. This file contains relevant -settings if you are using pthreads or another thread library. -See section Using the Library with a Thread Package. The `configure' script created this -file from the `settings.dist' file. Any permanent changes to these -settings should made to the `settings.dist' file. You then can run -`config.status' to re-create the `settings.h' file. - - - -
  7. The DMALLOC_SIZE variable gets auto-configured in -`dmalloc.h.2' but it may not generate correct settings for all -systems. You may have to alter the definitions in this file to get -things to stop complaining when you go to compile about the size -arguments to malloc routines. Comments on this please. - -
  8. Typing make should be enough to build `libdmalloc.a', -and `dmalloc' program. If it does not work, please see if there -are any notes in the contrib directory about your system-type. If not -and you figure your problem out, please send me some notes so future -users can profit from your experiences. - - - -

    NOTE: You may experience some errors compiling some of the -`return.h' assembly macros which attempt to determine the callers -address for logging purposes. See section Issues Important for Porting the Library. You may want to -first try disabling any compiler optimization flags. If this doesn't -work then you may need to disable the `USE_RETURN_MACROS' -variable in the `settings.h' file. -

    - - -

    NOTE: The code is dependent on an ANSI-C compiler. If the -configure script gives the `WARNING' that you do not have an ANSI-C -compiler, you may still be able to add some sort of option to your -compiler to make it ANSI. If there such is an option, please send it to -the author so it can be added to the configure script. -

    -
  9. If you use threads and did not add the --enable-threads -argument to configure, typing make threads should be enough to -build `libdmallocth.a' which is the threaded version of the -library. This may or may not work depending on the configuration -scripts ability to detect your local thread functionality. Feel free to -send me mail with improvements. - -

    See the section of the manual on threads for more information about -the operation of the library with your threaded program. See section Using the Library with a Thread Package. -

    -
  10. If you have a C++ compiler installed, the library should have -automatically built `libdmallocxx.a' which is the C++ version of -the library. If it was not done automatically, you can build it by -typing make cxx. You should link this library into your C++ -programs instead of `libdmalloc.a'. See the `dmallocc.cc' C++ -file which contains basic code to overload the new, new[], -delete, and delete[] C++ operators. My apologies on the -minimal C++ support. I am still living in a mostly C world. Any help -improving this interface without sacrificing portability would be -appreciated. - - - - -
  11. Typing make light should build and run the `dmalloc_t' test -program through a set of light trials. By default this will execute -`dmalloc_t' 5 times - each time will execute 10,000 malloc -operations in a very random manner. Anal folks can type make -heavy to up the ante. Use dmalloc_t --usage for the list of all -`dmalloc_t' options. - -
  12. Typing make install should install the `libdmalloc.a' -library in `/usr/local/lib', the `dmalloc.h' include file in -`/usr/local/include', and the `dmalloc' utility in -`/usr/local/bin'. You may also want to type make installth -to install the thread library into place and/or make installcc to -install the C++ library into place. - -

    You may have specified a `--prefix=PATH' option to configure in -which case `/usr/local' will have been replaced with `PATH'. -

    -
- -

See the "Getting Started" section to get up and running with the -library. See section Getting Started with the Library. -

2.2 Getting Started with the Library

- - -

This section should give you a quick idea on how to get going. -Basically, you need to do the following things to make use of the -library: -

-
    -
  1. Make sure you have downloaded the latest version of the library -available from the home page at URL http://dmalloc.com/. - -
  2. Follow the installation instructions on how to configure, -make, and install the library (i.e. type: make install). -See section How to Install the Library. - - - - - - - -
  3. You need to make sure that the library configuration and -build process above was able to locate one of the on_exit -function, atexit function, or had compiler destructor support. -If one of these functions or support is available then the dmalloc -library should be able to automatically shut itself down when the -program exits. This causes the memory statistics and unfreed -information to be dumped to the log file. However, if your system has -none of the above, then you will need to call dmalloc_shutdown -yourself before your program exits. - - - - - - -
  4. To get the dmalloc utility to work you need to add an alias for -dmalloc to your shell's runtime configuration file if supported. The -idea is to have the shell capture the dmalloc program's output and -adjust the environment. - -

    After you add the alias to the shell config file you need to log out -and log back in to have it take effect, or you can execute the -appropriate command below on the command line directly. After you -setup the alias, if you enter dmalloc runtime and see any output -with DMALLOC_OPTIONS in it then the alias did not take effect. -

    -

    Bash, ksh, and zsh (http://www.zsh.org/) users should add the -following to their `.bashrc', `.profile', or `.zshrc' -file respectively (notice the -b option for bourne shell -output): -

    -
     
    function dmalloc { eval `command dmalloc -b $*`; }
-
    -

    If your shell does not support the command function then try: -

    -
     
    function dmalloc { eval `\dmalloc -b $*`; }
-

    or -

     
    function dmalloc { eval `/usr/local/bin/dmalloc -b $*`; }
-
    - - - -

    If you are still using csh or tcsh, you should add the following to -your `.cshrc' file (notice the -C option for c-shell -output): -

    -
     
    alias dmalloc 'eval `\dmalloc -C \!*`'
-
    - - -

    If you are using rc shell, you should add the following to your -`.rcrc' file (notice the -R option for rc-shell output): -

    -
     
    fn dmalloc {eval `{/usr/local/bin/dmalloc $*}}
-
    -
  5. Although not necessary, you may want to include `dmalloc.h' -in your C files and recompile. This will allow the library to report -the file/line numbers of calls that generate problems. See section Macros Providing File and Line Information. It should be inserted at the bottom of your include -files as to not conflict with wother includes. You may want to ifdef it -as well and compile with cc -DDMALLOC …: - -
     
    /* other includes above ^^^ */
-
-#ifdef DMALLOC
-#include "dmalloc.h"
-#endif
-
    - -
  6. Another optional task is to compile all of your source with the -`dmalloc.h' with the DMALLOC_FUNC_CHECK compilation flag. -This willallow the library to check all of the arguments of a number -of common string and utility routines. See section Checking of Function Arguments. - -
     
    cc -DDMALLOC -DDMALLOC_FUNC_CHECK file.c
-
    -
  7. Link the dmalloc library into your program. The dmalloc library -should probably be placed at or near the end of the library list. - -
  8. Enable the debugging features by typing dmalloc -l logfile --i 100 low (for example). You should not see any messages printed by -the dmalloc utility (see NOTE below). This will: - -
      -
    • Set the malloc logfile name to `logfile' (-l logfile). -For programs which change directories, you may want to specify the -full path to your logfile. - -
    • Have the library check itself every 100 iterations (-i 100). -This controls how fast your program will run. Larger numbers check -the heap less and so it will run faster. Lower numbers will be more -likely to catch memory problems. - -
    • Enable a number of debug features (low). You can -also try runtime for minimal checking or medium or -high for more extensive heap verification. - -
    • By default, the low, medium, and high values enable the -error-abort token which will cause the library to abort and -usually dump core immediately upon seeing an error. See section Generating a Core File on Errors. You can disable this feature by entering dmalloc -m -error-abort (-m for minus) to remove the error-abort token and -your program will just log errors and continue. - -
    - -

    dmalloc --usage will provide verbose usage info for the dmalloc -program. See section Dmalloc Utility Program. -

    -

    You may also want to install the `dmallocrc' file in your home -directory as `.dmallocrc'. This allows you to add your own -combination of debug tokens. See section Format of the Runtime Configuration File. -

    -

    NOTE: The output from the dmalloc utility should be captured by -your shell. If you see a bunch of stuff which includes the string -DMALLOC_OPTIONS then the alias you should have created above is -not working and he environmental variables are not being set. Make -sure you've logged out and back in to have the alias take effect. -

    -
  9. Run your program, examine the logfile that should have been -created by dmalloc_shutdown, and use its information to help -debug your program. - -

-

2.3.1 General Memory Terms and Concepts

- - -

Any program can be divided into 2 logical parts: text and data. Text is -the actual program code in machine-readable format and data is the -information that the text operates on when it is executing. The data, -in turn, can be divided into 3 logical parts according to where it is -stored: static, stack, and heap. -

- - -

Static data is the information whose storage space is compiled into the -program. -

-
 
/* global variables are allocated as static data */
-int numbers[10];
-
-main()
-{
-        …
-}
-
- - -

Stack data is data allocated at runtime to hold information used inside -of functions. This data is managed by the system in the space called -stack space. -

-
 
void foo()
-{
-        /* this local variable is stored on the stack */
-        float total;
-        …
-}
-
-main()
-{
-        foo();
-}
-
- - -

Heap data is also allocated at runtime and provides a programmer with -dynamic memory capabilities. -

-
 
main()
-{
-        /* the address is stored on the stack */
-        char * string;
-        …
-
-        /*
-         * Allocate a string of 10 bytes on the heap.  Store the
-         * address in string which is on the stack.
-         */
-        string = (char *)malloc(10);
-        …
-
-        /* de-allocate the heap memory now that we're done with it */
-        (void)free(string);
-        …
-}
-
-

It is the heap data that is managed by this library. -

-

Although the above is an example of how to use the malloc and free -commands, it is not a good example of why using the heap for runtime -storage is useful. -

-

Consider this: You write a program that reads a file into memory, -processes it, and displays results. You would like to handle files with -arbitrary size (from 10 bytes to 1.2 megabytes and more). One problem, -however, is that the entire file must be in memory at one time to do the -calculations. You don't want to have to allocate 1.2 megabytes when you -might only be reading in a 10 byte file because it is wasteful of system -resources. Also, you are worried that your program might have to handle -files of more than 1.2 megabytes. -

-

A solution: first check out the file's size and then, using the -heap-allocation routines, get enough storage to read the entire file -into memory. The program will only be using the system resources -necessary for the job and you will be guaranteed that your program can -handle any sized file. -

- -

2.3.2 Functionality Supported by All Malloc Libraries

- - -

All malloc libraries support 4 basic memory allocation commands. These -include malloc, calloc, realloc, and free. For -more information about their capabilities, check your system's manual -pages - in unix, do a man 3 malloc. -

- -
-
Function: void *malloc ( unsigned int size ) - -
-

Usage: pnt = (type *)malloc(size) -

-

The malloc routine is the basic memory allocation routine. It allocates -an area of size bytes. It will return a pointer to the space -requested. -

-
-
-
Function: void *calloc ( unsigned int number, unsigned intsize ) - -
-
- - - -

Usage: pnt = (type *)calloc(number, size) -

-

The calloc routine allocates a certain number of items, each of -size bytes, and returns a pointer to the space. It is -appropriate to pass in a sizeof(type) value as the size argument. -

-

Also, calloc nulls the space that it returns, assuring that the memory -is all zeros. -

-
-
-
Function: void *realloc ( void *old_pnt, unsigned int new_size ) - -
-
- -

Usage: new_pnt = (type *)realloc(old_pnt, new_size) -

-

The realloc function expands or shrinks the memory allocation in -old_pnt to new_size number of bytes. Realloc copies as -much of the information from old_pnt as it can into the -new_pnt space it returns, up to new_size bytes. If there -is a problem allocating this memory, 0L will be returned. -

-

If the old_pnt is 0L then realloc will do the equivalent of a -malloc(new_size). If new_size is 0 and old_pnt is -not 0L, then it will do the equivalent of free(old_pnt) and will -return 0L. -

-
-
-
Function: void free ( void *pnt ) - -
-
- -

Usage: free(pnt) -

-

The free routine releases allocation in pnt which was returned by -malloc, calloc, or realloc back to the heap. This allows other parts of -the program to re-use memory that is not needed anymore. It guarantees -that the process does not grow too big and swallow a large portion of -the system resources. -

-
- -

WARNING: there is a quite common myth that all of the space that -is returned by malloc libraries has already been cleared. Only -the calloc routine will zero the memory space it returns. -

2.4 General Features of the Library

- - -

The debugging features that are available in this debug malloc library -can be divided into a couple basic classifications: -

-
-
file and line number information
-
- -

One of the nice things about a good debugger is its ability to provide -the file and line number of an offending piece of code. This library -attempts to give this functionality with the help of cpp, the C -preprocessor. See section Macros Providing File and Line Information. -

-
-
return-address information
-
-

To debug calls to the library from external sources (i.e. those files -that could not use the allocation macros), some facilities have been -provided to supply the caller's address. This address, with the help of -a debugger, can help you locate the source of a problem. See section Getting Caller Address Information. -

-
-
fence-post (i.e. bounds) checking
-
- - -

Fence-post memory is the area immediately above or below memory -allocations. It is all too easy to write code that accesses above or -below an allocation - especially when dealing with arrays or strings. -The library can write special values in the areas around every -allocation so it will notice when these areas have been overwritten. -See section Diagnosing Fence-Post Overwritten Memory. -

-

NOTE: The library cannot notice when the program reads -from these areas, only when it writes values. Also, fence-post checking -will increase the amount of memory the program allocates. -

-
-
heap-constancy verification
-
-

The administration of the library is reasonably complex. If any of the -heap-maintenance information is corrupted, the program will either crash -or give unpredictable results. -

-

By enabling heap-consistency checking, the library will run through its -administrative structures to make sure all is in order. This will mean -that problems will be caught faster and diagnosed better. -

-

The drawback of this is, of course, that the library often takes quite a -long time to do this. It is suitable to enable this only during -development and debugging sessions. -

-

NOTE: the heap checking routines cannot guarantee that the tests -will not cause a segmentation-fault if the heap administration -structures are properly (or improperly if you will) overwritten. In -other words, the tests will verify that everything is okay but may not -inform the user of problems in a graceful manner. -

-
-
logging statistics
-
- - - -

One of the reasons why the debug malloc library was initially developed -was to track programs' memory usage - specifically to locate -memory leaks which are places where allocated memory is never -getting freed. See section Tracking Down Non-Freed Memory. -

-

The library has a number of logging capabilities that can track un-freed -memory pointers as well as runtime memory usage, memory transactions, -administrative actions, and final statistics. -

-
-
examining freed memory
-
- -

Another common problem happens when a program frees a memory pointer but -goes on to use it again by mistake. This can lead to mysterious crashes -and unexplained problems. -

-

To combat this, the library can write special values into a block of -memory after it has been freed. This serves two purposes: it will make -sure that the program will get garbage data if it trying to access the -area again, and it will allow the library to verify the area later for -signs of overwriting. -

-
- -

If any of the above debugging features detect an error, the library will -try to recover. If logging is enabled then an error will be logged with -as much information as possible. -

-

The error messages that the library displays are designed to give the -most information for developers. If the error message is not -understood, then it is most likely just trying to indicate that a part -of the heap has been corrupted. -

- - -

The library can be configured to quit immediately when an error is -detected and to dump a core file or memory-image. This can be -examined with a debugger to determine the source of the problem. The -library can either stop after dumping core or continue running. -See section Generating a Core File on Errors. -

- - -

NOTE: do not be surprised if the library catches problems with -your system's routines. It took me hours to finally come to the -conclusion that the localtime call, included in SunOS release 4.1, -overwrites one of its fence-post markers. -

2.5 How the Library Checks Your Program

- -

This is one of the newer sections of the library implying that it is -incomplete. If you have any questions or issues that you'd like to see -handled here, please let me know. -

-

The dmalloc library replaces the heap library calls normally found in -your system libraries with its own versions. When you make a call to -malloc (for example), you are calling dmalloc's version of the memory -allocation function. When you allocate memory with these functions, the -dmalloc library keeps track of a number of pieces of debugging -information about your pointer including: where it was allocated, -exactly how much memory was requested, when the call was made, etc.. -This information can then be verified when the pointer is freed or -reallocated and the details can be logged on any errors. -

-

Whenever you reallocate or free a memory address, the dmalloc library -always performs a number of checks on the pointer to make sure that it -is valid and has not been corrupted. You can configure the library to -perform additional checks such as detected fence-post writing. The -library can also be configured to overwrite memory with non-zeros (only -if calloc is not called) when it is allocated and erase the memory when -the pointers are freed. -

- -

In addition to per-pointer checks, you can configure the library to -perform complete heap checks. These complete checks verify all -internal heap structures and include walking all of the known -allocated pointers to verify each one in turn. You need this level of -checking to find random pointers in your program which got corrupted -but that won't be freed for a while. To turn on these checks, you -will need to enable the check-heap debug token. See section Description of the Debugging Tokens. By default this will cause the heap to be fully checked each -and every time dmalloc is called whether it is a malloc, free, -realloc, or another dmalloc overloaded function. -

-

Performing a full heap check can take a good bit of CPU and it may be -that you will want to run it sporadically. This can be accomplished in -a couple different ways including the '-i' interval argument to the -dmalloc utility. See section Dmalloc Utility Program. This will cause the check to -be run every N-th time. For instance, 'dmalloc -i 3' will cause the -heap to be checked before every 3rd call to a memory function. Values -of 100 or even 1000 for high memory usage programs are more useful than -smaller ones. -

- - - -

You can also cause the program to start doing detailed heap checking -after a certain point. For instance, with 'dmalloc -s 1000' option, you -can tell the dmalloc library to enable the heap checks after the 1000th -memory call. Examine the dmalloc log file produced and use the -iteration count if you have LOG_ITERATION_COUNT enabled in your -`settings.h' file. -

-

The start option can also have the format `file:line'. For -instance, if it is set to `dmalloc_t.c:126', dmalloc will start -checking the heap after it sees a dmalloc call from the -`dmalloc_t.c' file, line number 126. If you use -`dmalloc_t.c:0', with a 0 line number, then dmalloc will start -checking the heap after it sees a call from anywhere in the -`dmalloc_t.c' file. -

3.1 Macros Providing File and Line Information

- - -

By including `dmalloc.h' in your C files, your calls to malloc, -calloc, realloc, recalloc, memalign, valloc, strdup, and free are -replaced with calls to _dmalloc_malloc, _dmalloc_realloc, and -_dmalloc_free with various flags. Additionally the library replaces -calls to xmalloc, xcalloc, xrealloc, xrecalloc, xmemalign, xvalloc, -xstrdup, and xfree with associated calls. -

-

These macros use the c-preprocessor __FILE__ and __LINE__ -macros which get replaced at compilation time with the current file and -line-number of the source code in question. The routines use this -information to produce verbose reports on memory problems. -

-
 
not freed: '0x38410' (22 bytes) from 'dmalloc_t.c:92'
-
-

This line from a log file shows that memory was not freed from file -`dmalloc_t.c' line 92. See section Tracking Down Non-Freed Memory. -

- - - - - -

You may notice some non standard memory allocation functions in the -above list. Recalloc is a routine like realloc that reallocates -previously allocated memory to a new size. If the new memory size is -larger than the old, recalloc initializes the new space to all zeros. -This may or may not be supported natively by your operating system. -Memalign is like malloc but should insure that the returned pointer is -aligned to a certain number of specified bytes. Currently, the memalign -function is not supported by the library. It defaults to returning -possibly non-aligned memory for alignment values less than a block-size. -Valloc is like malloc but insures that the returned pointer will be -aligned to a page boundary. This may or may not be supported natively -by your operating system but is fully supported by the library. Strdup -is a string duplicating routine which takes in a null terminated string -pointer and returns an allocated copy of the string that will need to be -passed to free later to deallocate. -

-

The X versions of the standard memory functions (xmalloc, xfree, etc.) -will print out an error message to standard error and will stop if the -library is unable to allocate any additional memory. It is useful to -use these routines instead of checking everywhere in your program for -allocation routines returning NULL pointers. -

-

WARNING: If you are including the `dmalloc.h' file in your -sources, it is recommended that it be at the end of your include file -list because dmalloc uses macros and may try to change declarations of -the malloc functions if they come after it. -

- -
- - - - - - - - - - - - - - - - - -
[ < ][ > ]   [ << ][ Up ][ >> ]         [Top][Contents][Index][ ? ]
-

3.2 Getting Caller Address Information

- - -

Even though the allocation macros can provide file/line information for -some of your code, there are still modules which either you can't -include `dmalloc.h' (such as library routines) or you just don't -want to. You can still get information about the routines that call -dmalloc function from the return-address information. To accomplish -this, you must be using this library on one of the supported -architecture/compilers. See section Issues Important for Porting the Library. -

- - -

The library attempts to use some assembly hacks to get the -return-address or the address of the line that called the dmalloc -function. If you have unfreed memory that does not have associated file -and line information, you might see the following non-freed memory -messages. -

-
 
not freed: '0x38410' (22 bytes) from 'ra=0xdd2c'
-not freed: '0x38600' (10232 bytes) from 'ra=0x10234d'
-not freed: '0x38220' (137 bytes) from 'ra=0x82cc'
-
- -

With the help of a debugger, these return-addresses (or ra) can then be -identified. I've provided a `ra_info.pl' perl script in the -`contrib/' directory with the dmalloc sources which seems to work -well with gdb. You can also use manual methods for gdb to find the -return-address location. See section Translating Return Addresses into Code Locations. -

- -
- - - - - - - - - - - - - - - - - -
[ < ][ > ]   [ << ][ Up ][ >> ]         [Top][Contents][Index][ ? ]
-

3.3 Checking of Function Arguments

- - -

One potential problem with the library and its multitude of checks and -diagnoses is that they only get performed when a dmalloc function is -called. One solution this is to include `dmalloc.h' and compile -your source code with the DMALLOC_FUNC_CHECK flag defined and -enable the check-funcs token. See section Description of the Debugging Tokens. -

-
 
cc -DDMALLOC -DDMALLOC_FUNC_CHECK file.c
-
-

NOTE: Once you have compiled your source with DMALLOC_FUNC_CHECK -enabled, you will have to recompile with it off to disconnect the -library. See section How to Disable the library. -

-

WARNING: You should be sure to have `dmalloc.h' included at -the end of your include file list because dmalloc uses macros and may -try to change declarations of the checked functions if they come after -it. -

-

When this is defined dmalloc will override a number of functions and -will insert a routine which knows how to check its own arguments and -then call the real function. Dmalloc can check such functions as -bcopy, index, strcat, and strcasecmp. For -the full list see the end of `dmalloc.h'. -

-

When you call strlen, for instance, dmalloc will make sure the -string argument's fence-post areas have not been overwritten, its file -and line number locations are good, etc. With bcopy, dmalloc -will make sure that the destination string has enough space to store the -number of bytes specified. -

-

For all of the arguments checked, if the pointer is not in the heap then -it is ignored since dmalloc does not know anything about it. -

- -
- - - - - - - - - - - - - - - - - -
[ < ][ > ]   [ << ][ Up ][ >> ]         [Top][Contents][Index][ ? ]
-

3.4 Generating a Core File on Errors

- - -

If the error-abort debug token has been enabled, when the -library detects any problems with the heap memory, it will immediately -attempt to dump a core file. See section Description of the Debugging Tokens. Core files are a -complete copy of the program and it's state and can be used by a -debugger to see specifically what is going on when the error occurred. -See section Using Dmalloc With a Debugger. By default, the low, medium, and high -arguments to the library utility enable the error-abort token. -You can disable this feature by entering dmalloc -m error-abort -(-m for minus) to remove the error-abort token and your program -will just log errors and continue. You can also use the -error-dump token which tries to dump core when it sees an error -but still continue running. See section Description of the Debugging Tokens. -

- - - - - - -

When a program dumps core, the system writes the program and all of -its memory to a file on disk usually named `core'. If your -program is called `foo' then your system may dump core as -`foo.core'. If you are not getting a `core' file, make sure -that your program has not changed to a new directory meaning that it -may have written the core file in a different location. Also insure -that your program has write privileges over the directory that it is -in otherwise it will not be able to dump a core file. Core dumps are -often security problems since they contain all program memory so -systems often block their being produced. You will want to check your -user and system's core dump size ulimit settings. -

- - - - -

The library by default uses the abort function to dump core -which may or may not work depending on your operating system. If the -following program does not dump core then this may be the problem. -See KILL_PROCESS definition in `settings.dist'. -

-
 
main()
-{
-  abort();
-}
-
-

If abort does work then you may want to try the following -setting in `settings.dist'. This code tries to generate a -segmentation fault by dereferencing a NULL pointer. -

-
 
#define KILL_PROCESS    { int *_int_p = 0L; *_int_p = 1; }

3.5 Additional Non-standard Routines

- - -

The library has a number of variables that are not a standard part of -most malloc libraries: -

- - - - - -
-
Variable: int dmalloc_errno - -
-

This variable stores the internal dmalloc library error number like errno -does for the system calls. It can be passed to dmalloc_strerror() -(see below) to get a string version of the error. It will have a value -of zero if the library has not detected any problems. -

-
- - - - - -
-
Variable: char* dmalloc_logpath - -
-

This variable can be used to set the dmalloc log filename. The env -variable DMALLOC_LOGFILE overrides this variable. -

- -
- -

Additionally the library provides a number of non-standard malloc -routines: -

- - - - -
-
Function: void dmalloc_shutdown ( void ) - -
-
- - -

This function shuts the library down and logs the final statistics and -information especially the non-freed memory pointers. The library has -code to support auto-shutdown if your system has the on_exit() -call, atexit() call, or compiler destructor support (see -`conf.h'). If you do not have these, then dmalloc_shutdown -should be called right before exit() or as the last function in -main(). -

-
 
main()
-{
-        …
-        dmalloc_shutdown();
-        exit(0);
-}
-
- - - - - - -
-
Function: int dmalloc_verify ( char * pnt ) - -
-

This function verifies individual memory pointers that are suspect of -memory problems. To check the entire heap pass in a NULL or 0 pointer. -The routine returns DMALLOC_VERIFY_ERROR or DMALLOC_VERIFY_NOERROR. -

-

NOTE: `dmalloc_verify()' can only check the heap with the -functions that have been enabled. For example, if fence-post checking -is not enabled, `dmalloc_verify()' cannot check the fence-post -areas in the heap. -

- - - - - - -
-
Function: unsigned-int dmalloc_debug ( const unsigned int flags ) - -
-

This routine sets the debug functionality flags and returns the -previous flag value. It is helpful in server or cgi-bin programs -where environmental variables cannot be used. See section Debugging Memory in a Server or Cgi-Bin Process. For instance, if debugging should never be enabled for a -program, a call to dmalloc_debug(0) as the first call in -main() will disable all the memory debugging from that point -on. -

-

NOTE: you cannot add or remove certain flags such as signal -handlers since they are setup at initialization time only. -

-

NOTE: you can also use dmalloc_debug_setup below. -

-
- - - - - -
-
Function: unsigned-int dmalloc_debug_current ( void ) - -
-

This routine returns the current debug functionality value value. This -allows you to save a copy of the debug dmalloc settings to be changed -and then restored later. -

-
- - - - - - - - -
-
Function: void dmalloc_debug_setup ( const char * options_str ) - -
-

This routine sets the global debugging functionality as an option -string. Normally this would be passed in in the DMALLOC_OPTIONS -environmental variable. This is here to override the env or for -circumstances where modifying the environment is not possible or does -not apply such as servers or cgi-bin programs. See section Debugging Memory in a Server or Cgi-Bin Process. -

-

Some examples: -

-
 
/*
- * debug tokens high, threaded lock-on at 20,
- * log to dmalloc.%p (pid)
- */
-dmalloc_debug_setup("debug=0x4f46d03,lockon=20,log=dmalloc.%p");
-
-/*
- * turn on some debug tokens directly and log to the
- * file 'logfile'
- */
-dmalloc_debug_setup(
-  "log-stats,log-non-free,check-fence,log=logfile");

Function: int dmalloc_examine ( const DMALLOC_PNT pnt, DMALLOC_SIZE * user_size_p, DMALLOC_SIZE * total_size_p, char ** file_p, int * line_p, DMALLOC_PNT * ret_addr_p, unsigned long * user_mark_p, unsigned long * seen_p ) - -
-
-

This function returns the size of a pointer's allocation as well as the -total size given including administrative overhead, file and line or the -return-address from where it was allocated, the last pointer when the -pointer was "used", and the number of times the pointer has been "seen". -It will return DMALLOC_NOERROR or DMALLOC_ERROR depending on whether pnt -is good or not. -

-

NOTE: This function is certainly not provided by most if -not all other malloc libraries. -

-
- - - - - -
-
Function: void dmalloc_track ( const dmalloc_track_t track_func ) - -
-

Register an allocation tracking function which will be called each time -an allocation occurs. Pass in NULL to disable. To take a look at what -information is provided, see the dmalloc_track_t function typedef in -dmalloc.h. -

-
- - - - - - - - - -
-
Function: unsigned-long dmalloc_mark ( void ) - -
-

Return to the caller the current "mark" which can be used later to log -the pointers which have changed since this mark with the -dmalloc_log_changed function. Multiple marks can be saved and -used. -

-

This is very useful when using the library with a server which does -not exit. You can then save a mark before a transaction or event -happens and then check to see what has changed using the -dmalloc_log_changed function below. See section Debugging Memory in a Server or Cgi-Bin Process. -

-

If you LOG_ITERATION enabled in your `settings.h' file then -the entries in the log file will be prepended with the number of memory -transactions that the library has handled so far. You can also enable -LOG_PNT_ITERATION in `settings.h' to store the memory -transaction number with each pointer. -

-
- - - - - - -
-
Function: unsigned-long dmalloc_memory_allocated ( void ) - -
-

Return to the caller the total number of bytes that have been allocated -by the library. This is not the current in use but the total number of -bytes returned by allocation functions. -

-
- - - - - -
-
Function: unsigned-int dmalloc_page_size ( void ) - -
-

Return to the caller the memory page-size being used by the library. -This should be the same value as the one returned by the -getpagesize() function, if available. -

-
- - - - - - -
-
Function: unsigned-long dmalloc_count_changed ( const unsigned long mark, const int not_freed_b, const int free_b ) - -
-

Count the pointers that have changed since the mark which was returned by -dmalloc_mark. If not_freed_b is set to non-0 then count the -pointers that have not been freed. If free_b is set to non-0 -then count the pointers that have been freed. -

-

This can be used in conjunction with the dmalloc_mark() -function to help servers which never exit ensure that transactions or -events are not leaking memory. See section Debugging Memory in a Server or Cgi-Bin Process. -

-
 
unsigned long mark = dmalloc_mark() ;
-…
-assert(dmalloc_count_changed(mark, 1, 0) == 0) ;
-
-
- - - - - - -
-
Function: void dmalloc_log_stats ( void ) - -
-

This routine outputs the current dmalloc statistics to the log file. -

- - - - - - -
-
Function: void dmalloc_log_unfreed ( void ) - -
-

This function logs the unfreed-memory information to the log file. -This is also useful to log the currently allocated points to the log -file to be compared against another dump later on. -

-
- - - - - - - -
-
Function: void dmalloc_log_changed ( const unsigned long mark, const int not_freed_b, const int freed_b, const int details_b ) - -
-

Log the pointers that have changed since the mark which was returned by -dmalloc_mark. If not_freed_b is set to non-0 then log the -pointers that have not been freed. If free_b is set to non-0 -then log the pointers that have been freed. If details_b set to -non-0 then log the individual pointers that have changed otherwise just -log the summaries. -

-

This can be used in conjunction with the dmalloc_mark() -function to help servers which never exit find transactions or events -which are leaking memory. See section Debugging Memory in a Server or Cgi-Bin Process. -

-
- - - - - - -
-
Function: void dmalloc_vmessage ( const char * format, va_list args ) - -
-

Write a message into the dmalloc logfile using vprintf-like arguments. -

-
- - - - - - -
-
Function: void dmalloc_message ( const char * format, ... ) - -
-

Write a message into the dmalloc logfile using printf-like arguments. -

-
- - - - - - - -
-
Function: void dmalloc_get_stats ( DMALLOC_PNT * heap_low_p, DMALLOC_PNT * heap_high_p, unsigned long * total_space_p, unsigned long * user_space_p, unsigned long * current_allocated_p, unsigned long * current_pnt_np, unsigned long * max_allocated_p, unsigned long * max_pnt_np, unsigned long * max_one_p) - -
-

This function return a number of statistics about the current heap. -The pointers heap_low_p and heap_high_p will be set to -the low and high spots in the heap. total_space_p will be set -to the total space in the heap including user space, administrative -space, and overhead. user_space_p will be set to the space -given to the user process (allocated and free space). -current_allocated_p will be set to the current allocated space -given to the user process. current_pnt_np will be set to the -current number of pointers allocated by the user process. -max_allocated_p will be set to the maximum allocated space -given to the user process. max_pnt_np will be set to the -maximum number of pointers allocated by the user process. -max_on_p will be set to the maximum space allocated with one -call by the user process. -

-
- - - - - - -
-
Function: const-char* dmalloc_strerror ( const int error_number ) - -
-

This function returns the string representation of the error value in -error_number (which probably should be dmalloc_errno). This -allows the logging of more verbose memory error messages. -

-

You can also display the string representation of an error value by a -call to the `dmalloc' program with a `-e #' option. -See section Dmalloc Utility Program. -

3.6 Description of the Internal Error Codes

- - -

The following error codes are defined in `error_val.h'. They are -used by the library to indicate a detected problem. They can be caused -by the user (`ERROR_TOO_BIG') or can indicate an internal library -problem (`ERROR_SLOT_CORRUPT'). The `dmalloc' utility can -give you the string version of the error with the -e argument: -

-
 
$ dmalloc -e 60
-dmalloc: dmalloc_errno value '60' = 
-   'pointer is not on block boundary'
-
-

Here are the error codes set by the library. They are non contiguous on -purpose because I add and delete codes all of the time and there are -sections for various error-code types. -

-
-
- - - - - - -
-
1 (ERROR_NONE) no error
-

No error. It is good coding practice to set the no-error code to be -non-0 value because it forces you to set it explicitly. -

- - - - - - - -
-
2 (INVALID_ERROR)
-

Invalid error number. If the library outputs this error then your -dmalloc utility may be out of date with the library you linked -against. This will be returned with all error codes not listed here. -

- - - - - - - -
-
10 (ERROR_BAD_SETUP) initialization and setup failed
-

Bad setup value. This is currently unused but it is intended to report -on invalid setup configuration information. -

- - - - - - - - - -
-
11 (ERROR_IN_TWICE) malloc library has gone recursive
-

Library went recursive. This usually indicates that you are not using -the threaded version of the library. Or if you are then you are not -using the `-o' "lock-on" option. See section Using the Library with a Thread Package. -

- - - - - - - -
-
13 (ERROR_LOCK_NOT_CONFIG) thread locking has not been configured
-

Thread locking has not been configured. This indicates that you -attempted to use the `-o' "lock-on" option without linking with -the thread version of the library. You should probably be using --ldmallocth not -ldmalloc when you are linking. -Or you should include …/lib/libdmallocth.a on your -compilation line. -

- - - - - - - - - -
-
20 (ERROR_IS_NULL) pointer is null
-

Pointer is null. The program passed a NULL (0L) pointer to free -and you have the error-free-null token enabled. -

- - - - - - - - -
-
21 (ERROR_NOT_IN_HEAP) pointer is not pointing to heap data space
-

Pointer is not pointing to heap data space. This means that the program -passed an out-of-bounds pointer to free or realloc. This -could be someone trying to work with a wild pointer or trying to free a -pointer from a different source than malloc. -

- - - - - - - - - - -
-
22 (ERROR_NOT_FOUND) cannot locate pointer in heap
-

Cannot locate pointer in heap. The user passed in a pointer which the -heap did not know about. Either this pointer was allocated by some -other mechanism (like mmap or sbrk directly) or it is a -random invalid pointer. -

-

In some rare circumstances, sometimes seen with shared libraries, there -can be two separate copies of the dmalloc library in a program. Each -one does not know about the pointers allocated by the other. -

- - - - - - - -
-
23 (ERROR_IS_FOUND) found pointer the user was looking for
-

This indicates that the pointer specified in the address part of the -environmental variable was discovered by the library. See section Environment Variable Name and Features. This error is useful so you can put a breakpoint in a -debugger to find where a particular address was allocated. See section Using Dmalloc With a Debugger. -

- - - - - - - -
-
24 (ERROR_BAD_FILE) possibly bad .c filename pointer
-

A possibly invalid filename was discovered in the dmalloc administrative -sections. This could indicate some corruption of the internal tables. -It also could mean that you have a source file whose name is longer than -100 characters. See MAX_FILE_LENGTH in the `settings.dist' -file. -

- - - - - - - -
-
25 (ERROR_BAD_LINE) possibly bad .c file line-number
-

A line-number was out-of-bounds in the dmalloc administrative sections. -This could indicate some corruption of the internal tables. It also -could mean that you have a source file containing more than 30000 -lines of code. See MAX_LINE_NUMBER in the `settings.dist' -file. -

- - - - - - - -
-
26 (ERROR_UNDER_FENCE) failed UNDER picket-fence magic-number check
-

This indicates that a pointer had its lower bound picket-fence magic -number overwritten. If the check-fence token is enabled, the -library writes magic values above and below allocations to protect -against overflow. Most likely this is because a pointer below it went -past its allocate and wrote into the next pointer's space. -

- - - - - - - -
-
27 (ERROR_OVER_FENCE) failed OVER picket-fence magic-number check
-

This indicates that a pointer had its upper bound picket-fence magic -space overwritten. If the check-fence token is enabled, the -library writes magic values above and below allocations to protect -against overflow. Most likely this is because an array or string -allocation wrote past the end of the allocation. -

-

Check for improper usage of strcat, sprintf, -strcpy, and any other functions which work with strings and do -not protect themselves by tracking the size of the string. These -functions should always be replaced with: strncat, -snprintf, strncpy, and others. -

- - - - - - - -
-
28 (ERROR_WOULD_OVERWRITE) use of pointer would exceed allocation
-

This error is generated by the function pointer checking code usually -enabled with the check-funcs token. Dmalloc overloads a number of -string and memory copying functions and verifies that the buffers (if -allocated in the heap) would not be overwritten by the function. -

- - - - - - - -
-
30 (ERROR_NOT_START_BLOCK) pointer is not to start of memory block
-

This indicates that the user passed in a pointer to be freed or -reallocated that was not at the start of the allocation. You would get -this error, for example, if you allocate and get pointer X but -then try to free X+1. -

- - - - - - - -
-
40 (ERROR_BAD_SIZE) invalid allocation size
-

This error indicates that a size value in the internal structures of the -library were corrupted. This could be a random pointer problem, pointer -overflow, or some other corruption. -

- - - - - - - -
-
41 (ERROR_TOO_BIG) largest maximum allocation size exceeded
-

An allocation asked for memory larger than the configured maximum. This -is a user configured setting. See LARGEST_ALLOCATION in the -`settings.dist' file. It is used to protect against wild -allocation sizes. If you have super large allocation sizes then you -should tune the LARGEST_ALLOCATION value appropriately. -

- - - - - - - -
-
43 (ERROR_ALLOC_FAILED) could not grow heap by allocating memory
-

The library could not allocate more heap space and the program has run -out of memory. This could indicate that you've overflowed some system -imposed limit. On many operation systems, the ulimit call can -tune system defaults. The library uses a lot more memory compared to -the system malloc library because it stores a lot more information -about the allocated pointers. -

- - - -

NOTE: This also may be due to an inability of your operating -system to use the mmap system call to allocate memory. You may -need to force the USE_MMAP setting to be 0. Please use the -forums at URL http://dmalloc.com/ to report issues with this. -

- - - - - - - - -
-
45 (ERROR_OVER_LIMIT) over user specified allocation limit
-

The library has allocated more memory than was specified in the -memory-limit environmental variable. See section Environment Variable Name and Features. -

- - - - - - - -
-
60 (ERROR_NOT_ON_BLOCK) pointer is not on block boundary
-

The user tried to free or realloc a pointer that was not pointing to a -block boundary. You would get this error, for example, if you allocate -and get pointer X but then try to free X+1. -

- - - - - - - -
-
61 (ERROR_ALREADY_FREE) tried to free previously freed pointer
-

The user tried to free a pointer than has already been freed. This is a -very common mistake and can lead to serious problems. It can be because -a destructor is being called twice for some reason. Although tracking -down the specific source is highly recommended, it is good to set -pointers to NULL (0L) after you free them as a rule. -

- - - - - - - - - -
-
67 (ERROR_FREE_OVERWRITTEN) free space has been overwritten
-

If either the free-blank or check-blank tokens are enabled -then the library will overwrite memory when it is freed with the -"dmalloc-free" byte (hex 0xdf, octal 0337, decimal 223). If the -program writes into this space, then the library will detect the write -and trigger this error. This could indicate that the program is using a -pointer after it has been freed. -

- - - - - - - -
-
70 (ERROR_ADMIN_LIST) bad admin structure list
-

An internal corruption in the library's administrative structures has -been detected. This could be a random pointer problem, pointer -overflow, or some other corruption. -

- - - - - - - -
-
72 (ERROR_ADDRESS_LIST) internal address list corruption
-

An internal corruption in the library's administrative structures has -been detected. This could be a random pointer problem, pointer -overflow, or some other corruption. -

- - - - - - - -
-
73 (ERROR_SLOT_CORRUPT) internal memory slot corruption
-

An internal corruption in the library's administrative structures has -been detected. This could be a random pointer problem, pointer -overflow, or some other corruption. -

3.7 How to Disable the library

- - -

If you would like to disable the library's detailed checking features -during a particularly allocation intensive section of code, you can do -something like the following: -

-
 
        unsigned int dmalloc_flags;
-        …
-        /* turn off all debug flags and save a copy of old value */
-        dmalloc_flags = dmalloc_debug(0);
-
-        /* section of a lot of allocations */
-        …
-        /* end of section */
-
-        /* restore the dmalloc flag setting */
-        dmalloc_debug(dmalloc_flags);
-
-

When you are finished with the development and debugging sessions, you -may want to disable the dmalloc library and put in its place either the -system's memory-allocation routines, gnu-malloc, or maybe your own. -Attempts have been made to make this a reasonably painless process. The -ease of the extraction depends heavily on how many of the library's -features your made use of during your coding. -

-

Reasonable suggestions are welcome as to how to improve this process -while maintaining the effectiveness of the debugging. -

-
    -
  • -If you want to totally disable the dmalloc library then you will -need to recompile all the C files that include `dmalloc.h' while -defining DMALLOC_DISABLE. This will cause the dmalloc macros to -not be applied. See section Macros Providing File and Line Information. - -
     
    cc -g -DDMALLOC_DISABLE file.c
-
    -

    An alternative is to surround the dmalloc.h inclusion or any -direct dmalloc references with an #ifdef DMALLOC and then just -remove the -DDMALLOC. -

    -
     
    #ifdef DMALLOC
-#include "dmalloc.h"
-#endif
-
-main()
-{
-  …
-
-#ifdef DMALLOC
-  dmalloc_verify(0L);
-#endif
-  return 0;
-}
-
    -
     
    // to get dmalloc information
-$ cc -DDMALLOC main.c
-
-// without dmalloc information
-$ cc main.c
-
    -
  • -If you compiled any of your source modules with DMALLOC_FUNC_CHECK -defined then you must first recompile all those modules without the flag -enabled. - -

    If you have disabled dmalloc with the DMALLOC_DISABLED flag or -never included `dmalloc.h' in any of your C files, then you will -not need to recompile your sources when you need to disable the library. -

    -

    If you get unresolved references like _dmalloc_malloc or -_dmalloc_bcopy then something was not disabled as it should have -been. -

3.8 Using the Library with C++

- - -

For those people using the C++ language, the library tries to configure -and build `libdmallocxx.a' library. This library should be linked -into your C++ programs instead of `libdmalloc.a'. -

- -

Dmalloc is not as good with C++ as C because the dynamic memory routines -in C++ are new() and delete() as opposed to -malloc() and free(). Since new and delete are usually not -used as functions but rather as x = new type, there is no easy -way for dmalloc to pass in file and line information unfortunately. The -`libdmallocxx.a' library provides the file `dmallocc.cc' which -effectively redirects new to the more familiar malloc and -delete to the more familiar free. -

-

NOTE: The author is not a C++ hacker so feedback in the form of -other hints and ideas for C++ users would be much appreciated. -

3.9 Using Dmalloc With a Debugger

- - -

Here are a number of possible scenarios for using the dmalloc library to -track down problems with your program. -

-

You should first enable a logfile filename and turn on a set of debug -features. You can use dmalloc -l logfile low to accomplish this. -If you are interested in having the error messages printed to your -terminal as well, enable the print-messages token by typing -dmalloc -p print-messages afterwards. See section Dmalloc Utility Program. -

- - -

Now you can enter your debugger (I use the excellent GNU debugger -gdb), and put a break-point in dmalloc_error() which is the -internal error routine for the library. When your program is run, it -will stop there if a memory problem is detected. -

-

If you are using GDB, I would recommend adding the contents of -`dmalloc.gdb' in the `contrib' subdirectory to your -`.gdbinit' file in your home directory. This enables the -dmalloc command which will prompt you for the arguments to the -dmalloc command and will set a break point in dmalloc_error() -automatically. -

- - -

If you are using shared libraries, you may want to execute the following -commands initially to load in dmalloc and other library symbols: -

-
 
(gdb) sharedlibrary
-(gdb) add-shared-symbol-files

-

3.9.1 Diagnosing General Problems with a Debugger

- - -

If your program stops at the dmalloc_error() routine then one -of a number of problems could be happening. Incorrect arguments could -have been passed to a malloc call: asking for negative number of -bytes, trying to realloc a non-heap pointer, etc.. There also could -be a problem with the system's allocations: you've run out of memory, -some other function in your program is using the heap allocation -functions mmap or sbrk, etc.. However, it is most -likely that some code that has been executed was naughty. -

-

To get more information about the problem, first print via the debugger -the dmalloc_errno variable to get the library's internal error code. -You can suspend your debugger and run dmalloc -e -value-returned-from-print to get an English translation of the error. -A number of the error messages are designed to indicate specific -problems with the library administrative structures and may not be -user-friendly. -

-

If the problem was due to the arguments or system allocations then the -source of the problem has been found. However, if some code did -something wrong, you may have some more work to do to locate the actual -problem. The check-heap token should be enabled and the interval -setting disabled or set to a low value so that the library can find the -problem as close as possible to its source. The code that was execute -right before the library halted, can then be examined closely for -irregularities. See section Description of the Debugging Tokens, See section Dmalloc Utility Program. -

- - -

You may also want to put calls to dmalloc_verify(0) in your code -before the section which generated the error. This should locate the -problem faster by checking the library's structures at that point. -See section Additional Non-standard Routines. -

- -
- - - - - - - - - - - - - - - - - -
[ < ][ > ]   [ << ][ Up ][ >> ]         [Top][Contents][Index][ ? ]
-

3.9.2 Tracking Down Non-Freed Memory

- - -

So you've run your program, examined the log-file and discovered (to -your horror) some un-freed memory. Memory leaks can become large -problems since even the smallest and most insignificant leak can starve -the program given the right circumstances. -

-
 
not freed: '0x45008' (12 bytes) from 'ra=0x1f8f4'
-not freed: '0x45028' (12 bytes) from 'unknown'
-not freed: '0x45048' (10 bytes) from 'argv.c:1077'
-  known memory not freed: 1 pointer, 10 bytes
-unknown memory not freed: 2 pointers, 24 bytes
-
-

Above you will see a sample of some non-freed memory messages from the -logfile. In the first line the `0x45008' is the pointer that was -not freed, the `12 bytes' is the size of the unfreed block, and the -`ra=0x1f8f4' or return-address shows where the allocation -originated from. See section Translating Return Addresses into Code Locations. -

-

The systems which cannot provide return-address information show -`unknown' instead, as in the 2nd line in the sample above. -

-

The `argv.c:1077' information from the 3rd line shows the file and -line number which allocated the memory which was not freed. This -information comes from the calls from C files which included -`dmalloc.h'. See section Macros Providing File and Line Information. -

-

At the bottom of the sample it totals the memory for you and breaks it -down to known memory (those calls which supplied the file/line -information) and unknown (the rest). -

-

Often, you may allocate memory in via strdup() or another -routine, so the logfile listing where in the strdup routine the -memory was allocated does not help locate the true source of the memory -leak - the routine that called strdup. Without a mechanism to -trace the calling stack, there is no way for the library to see who the -caller of the caller (so to speak) was. -

- - - - -

However, there is a way to track down unfreed memory in this -circumstance. You need to compile the library with -STORE_SEEN_COUNT defined in `conf.h'. The library will then -record how many times a pointer has been allocated or freed. It will -display the unfreed memory as: -

-
 
not freed: '0x45008|s3' (12 bytes) from 'ra=0x1f8f4'
-
-

The STORE_SEEN_COUNT option adds a `|s#' qualifier to the -address. This means that the address in question was seen `#' many -times. In the above example, the address `0x45008' was seen -`3' times. The last time it was allocated, it was not freed. -

-

How can a pointer be "seen" 3 times? Let say you strdup a -string of 12 characters and get address `0x45008' - this is #1 -time the pointer is seen. You then free the pointer (seen #2) but later -strdup another 12 character string and it gets the `0x45008' -address from the free list (seen #3). -

-

So to find out who is allocating this particular 12 bytes the 3rd time, -try dmalloc -a 0x45008:3. The library will stop the program the -third time it sees the `0x45008' address. You then enter a -debugger and put a break point at dmalloc_error. Run the program -and when the breakpoint is reached you can examine the stack frame to -determine who called strdup to allocate the pointer. -

-

To not bother with the STORE_SEEN_COUNT feature, you can also run -your program with the never-reuse token enabled. This token will -cause the library to never reuse memory that has been freed. Unique -addresses are always generated. This should be used with caution since -it may cause your program to run out of memory. -

- -

3.9.3 Diagnosing Fence-Post Overwritten Memory

- - -

For a definition of fence-posts please see the "Features" section. -See section General Features of the Library. -

-

To detect fence-post overruns, you need to enable the `check-fence' -token. See section Description of the Debugging Tokens. This pads your allocations with some extra -bytes at the front and the end and watches the space to make sure that -they don't get overwritten. NOTE: The library cannot detect if -this space gets read, only written. -

-

If you have encountered a fence-post memory error, the logfile should be -able to tell you the offending address. -

-
 
free: failed UNDER picket-fence magic-number checking: 
-pointer '0x1d008' from 'dmalloc_t.c:427'
-Dump of proper fence-bottom bytes: '\e\253\300\300\e\253\300\300'
-Dump of '0x1d008'-8: '\e\253\300\300WOW!\003\001pforger\023\001\123'
-
-

The above sample shows that the pointer `0x1d008' has had its lower -fence-post area overwritten. This means that the code wrote below the -bottom of the address or above the address right below this one. In the -sample, the string that did it was `WOW!'. -

-

The library first shows you what the proper fence-post information -should look like, and then shows what the pointer's bad information was. -If it cannot print the character, it will display the value as -`\ddd' where ddd are three octal digits. -

-

By enabling the check-heap debugging token and assigning the -interval setting to a low number, you should be able to locate -approximately when this problem happened. See section Description of the Debugging Tokens, -See section Dmalloc Utility Program. -

3.9.4 Translating Return Addresses into Code Locations

- - -

The following gdb commands help you translate the return-addresses (ra=) -entries in the logfile into locations in your code. I've provided a -`ra_info.pl' perl script in the `contrib/' directory with the -dmalloc sources which seems to work well with gdb. But, if you need to -do it manually, here are the commands in gdb to use. -

- - - -
 
# you may need to add the following commands to load in shared libraries
-(gdb) sharedlibrary
-(gdb) add-shared-symbol-files
-
-(gdb) x 0x10234d
-0x10234d <_findbuf+132>: 0x7fffceb7
-
-(gdb) info line *(0x82cc)
-Line 1092 of argv.c starts at pc 0x7540 and ends at 0x7550.
-
-

In the above example, gdb was used to find that the two non-freed memory -pointers were allocated in _findbuf() and in file argv.c line -1092 respectively. The `x address' (for examine) can always be -used on the return-addresses but the `info line *(address)' will -only work if that file was compiled using the -g option and has -not been stripped. This limitation may not be true in later versions of -gdb. -

3.10 Using the Library with a Thread Package

- - -

Threads are special operating system facilities which allow your -programs to have multiple threads of execution (hence the name). In -effect your program can be doing a number of things "at the same -time". This allows you to take full advantage of modern operating -system scheduling and multi-processor hardware. If I've already lost -you or if any of the terminology below does not make sense, see manuals -about POSIX threads (pthreads) before going any further. O'Reilly -publishes a pretty good pthreads manual for example. -

-

To use dmalloc with your threaded program, you will first need to make -sure that you are linking with `libdmallocth.a' which is the -threaded version of the library. The support for threads in dmalloc -should be adequate for most if not all testing scenarios. It provides -support for mutex locking itself to protect against race conditions that -result in multiple simultaneous execution. One of the major problems is -that most thread libraries uses malloc themselves. Since all of -dmalloc's initialization happens when a call to malloc is made, we may -be attempting to initialize or lock the mutex while the thread library -is booting up. A very bad thing since thread libraries don't expect to -recurse. -

- - -

The solution to this problem is to have the library not initialize or -lock its mutex variable until after a certain number of allocation calls -have been completed. If the library does not wait before initializing -the locks, the thread library will probably core dump. If it waits too -long then it can't protect itself from multiple execution and it will -abort or other bad things might happen. You adjust the number of times -to wait at runtime with the `lock-on' option to the dmalloc program -(for example dmalloc -o 20). See section Dmalloc Utility Program. Times -values between 5 and 30 are probably good although operating systems -will vary significantly. You know its too low if your program -immediately core dumps and too high if the dmalloc library says its gone -recursive although with low values, you might get either problem. -

-

An additional complexity is when we are initializing the lock before -mutex locking around the library. As mentioned, the initialization -itself may generate a malloc call causing the library to go recursive -and the pthread library to possibly core dump. With the THREAD_INIT_LOCK -setting defined in `settings.h', you can tune how many times before -we start locking to try and initialize the mutex lock. It defaults to 2 -which seems to work for me. If people need to have this runtime -configurable or would like to present an alternative default, please let -me know. -

-

So to use dmalloc with a threaded program, follow the following steps -carefully. -

-
    -
  1. Follow the installation instructions on how to configure, -make, and install the library but make sure to add the ---enable-threads argument to configure. See section How to Install the Library. - -
  2. Typing make should be enough to build the threaded versions -of the libraries including `libdmallocth.a'. - -
  3. Link the dmalloc threaded library into your program. The dmalloc -library should probably be placed at or near the end of the library -list. - -
  4. Enable the debugging options that you need by typing -dmalloc -l logfile -i 100 low (for example). dmalloc ---usage will provide verbose usage info for the dmalloc program. -See section Dmalloc Utility Program. - -
  5. Enable the "lock-on" option (for example dmalloc -o 20). -As explained above, you may have to try different values before getting -it right. Values between 5 and 30 are probably good. - -
  6. If you get a dmalloc error #13 `thread locking has not -been configured' then you have not compiled you program with the -threaded version of dmalloc or there was a problem building it. - -
  7. If everything works, you should be able to run your program, have -it not immediately crash, and the dmalloc library should not complain -about recursion. - -
- -

If you have any specific questions or would like addition information -posted in this section, please let me know. Experienced thread -programmers only please. -

3.11 Using the library with Cygwin environment.

- - -

The Cygwin environment is a Linux-like environment for Windows. It -provides Linux look and feel as well as a programming environment. See -URL http://www.cygwin.com/ for more details. -

- - - - -

Cygwin uses the GetEnvironmentVariableA function to read in -environmental variables instead of getenv. This functions are -used to get the value of the `DMALLOC_OPTIONS' variable which -sets the debugging options. See section Environment Variable Name and Features. -

- - - -

As of right now, dmalloc is not detecting the -GetEnvironmentVariableA function correctly so you may need to -tune the `conf.h' file to get it to work. See the sections on -HAVE_GETENVIRONMENTVARIABLEA and GETENV_SAVE settings. -Feedback is welcome here. -

-

If you still have problems reading in the environmental variables, you -can work around this issue. You can add some code into the -main function in your program to initialize the dmalloc flags -yourself. Here is a code sample: -

- - -
 
main(int argc, char **argv)
-{
-#ifdef DMALLOC
-  /*
-   * Get environ variable DMALLOC_OPTIONS and pass the settings string
-   * on to dmalloc_debug_setup to setup the dmalloc debugging flags.
-   */
-  dmalloc_debug_setup(getenv("DMALLOC_OPTIONS"));
-#endif
-
-  /* rest of code in main starts here */
-  …
-}
-
-

The #ifdef is just a good idea. I means that when debugging with -dmalloc you need to compile your code with -DDMALLOC. When you -are done debugging you can remove the flag and the call to -dmalloc_debug_setup will be removed. -

-

Please let me know if there is a better way to do this. -

3.12 Debugging Memory in a Server or Cgi-Bin Process

- - -

There are some specified challenges when trying to debug allocations -in processes which do not startup, run, and then shutdown. Server -processes (often called daemons) are those that are started (often at -system boot time) and run perpetually. Other processes which are -difficult to debug are CGI programs which are spawned by web servers -or when you want to start debugging inside of a child process. -

-
    -
  1. Build your server or cgi-bin program with the dmalloc library -like any other program. See section Getting Started with the Library. - -
  2. Add code into your program to enable the library flags to -perform the memory checks that you require. Since these programs -often do not run from the command line, you cannot use the dmalloc -utility program and modify the process environment. See section Dmalloc Utility Program. The library provides a couple of functions to set the -debugging flags when a program is running. - - - -
  3. To set the memory debugging flags, use the -dmalloc_debug_setup function which takes a string in the same -format of the `DMALLOC_OPTIONS' environmental variable. -See section Environment Variable Name and Features. Use the dmalloc utility with the --n no-changes argument to see the appropriate settings for the -`DMALLOC_OPTIONS' environmental variable. - -
     
    > dmalloc -n -l logfile high
-Outputed:
-DMALLOC_OPTIONS=debug=0x4f4ed03,log=logfile
-export DMALLOC_OPTIONS
-
    -

    So if you want to turn on high debugging and log to the file -`logfile' then you would copy the above `DMALLOC_OPTIONS' -value into a call to dmalloc_debug_setup. Notice that I have -surrounded the dmalloc code with an #ifdef DMALLOC so you'll -have to compile using the -DDMALLOC flag. -

    -
     
    main()
-{
-#ifdef DMALLOC
-  /* set the 'high' flags */
-  dmalloc_debug_setup("debug=0x4f47d03,log=logfile");
-#endif
-  …
-}
-
    -

    Please note that the dmalloc_debug_setup function does -not know about high, low, or other debug tokens but -needs the actual flag values. -

    -
  4. For earlier versions of the library (before 5.0.0) without -dmalloc_debug_setup, the dmalloc_debug function is -available to set the flags directly, but it cannot adjust the logfile -name and the other environment settings. You can use the dmalloc -utility program to see what the numerical equivalent of the high -token. - -
     
    > dmalloc -n high
-Outputed:
-DMALLOC_OPTIONS=debug=0x4f4ed03
-export DMALLOC_OPTIONS
-
    -

    You can then take the 0x4f4ed03 hexadecimal number and call -dmalloc_debug with that number. -

    -
     
    main()
-{
-#ifdef DMALLOC
-  /* set the 'high' flags */
-  dmalloc_debug(0x4f4ed03);
-#endif
-  …
-}
-
    -
  5. Even with the settings enabled, you may have problems getting -the logfile to be written if your program is running as `nobody' -or another user without permissions for security reasons. This is -especially true for cgi-bin programs. In this case you should specify -a full path to your malloc logfile in a world writable directory -(ex. dmalloc_debug_setup("debug=0x4f47d03,log=/var/tmp/malloc");). -Watch for programs which change into other directories and which may -cause logfiles specified as relative or local paths to be dropped in -other locations. You may always want to use a full path logfile. - -
  6. Once you have your settings enabled and your log is being -generated, you may now want to check out how your process is doing in -terms of unfreed memory. Since it is not shutting down, the automatic -unfreed log entries are not being dropped to the logfile. By using -the dmalloc_mark and dmalloc_log_changed functions, you -can set a mark point at a certain place inside of your program, and -then later see whether there are any unfreed pointers since the mark. - -
     
    main()
-{
-#ifdef DMALLOC
-  /* set the 'high' flags */
-  dmalloc_debug_setup("debug=0x4f47d03,log=logfile");
-#endif
-
-  while (1) {
-    /* accept a connection from a client */
-    accept_connection();
-
-    while (1) {
-#ifdef DMALLOC
-      unsigned long mark;
-      /* get the current dmalloc position */
-      mark = dmalloc_mark() ;
-#endif
-      /* process the connection */
-      if (process_connection() != PROCESS_OK) {
-        break;
-      }
-#ifdef DMALLOC
-      /*
-       * log unfreed pointers that have been added to
-       * the heap since mark
-       */
-      dmalloc_log_changed(mark,
-                          1 /* log unfreed pointers */,
-                          0 /* do not log freed pointers */,
-                          1 /* log each pnt otherwise summary */);
-#endif
-    }
-    /* close the connection with the client */
-    close_connection();
-  }
-  …
-}
-
    -

    Usually you would set the mark after the initializations and before -each transaction is processed. Then for each transaction you can use -dmalloc_log_changed to show the unfreed memory. -See section Additional Non-standard Routines. -

    -
  7. You can also use the dmalloc_log_stats function to dump -general information about the heap. Also, remember that you can use -the dmalloc_message and dmalloc_vmessage routines to -annotate the dmalloc logfile with details to help you debug memory -problems. See section Additional Non-standard Routines. - -

3.13 Explanation of the Logfile Output

- - -

Most of time you will be using the logfile output from library as the -sole information source for diagnosing problems in and getting -statistics for your program. -

-
 
1098918225: 3: Dmalloc version 'Version 5.5.2'
-1098918225: 3: flags = 0x4f4e503, logfile '/tmp/dmalloc.log'

-1098918225: 3: starting time = 1098918225
-1098918225: 3: process pid = 32406
-1098918226: 4: WARNING: tried to free(0) from foo.c:708'
-1098918228: 20: *** free: at 'unknown' pnt '0xed310080|s2': \

-1098918230: 50: ERROR: heap_check: free space was overwritten (err 67)
-1098918230: 50: error details: checking free pointer
-1098918230: 50: pointer '0x291c5' from 'unknown' prev access 'foo.c:787'
-
-

Here is a short example of some logfile information. Each of the -lines are prefixed by the time (in epoch seconds since 1/1/1970) and -the iteration or call count which is the number of times the library -has been called from malloc, free, verify, etc.. In the above -example, the first 5 log entries where written at epoch 1098918225 or -`Wed Oct 27 19:03:45 2004 EST' and they were generated by the 3rd -call to the library. See the `settings.dist' file entries to -tune what elements appear on each line: LOG_TIME_NUMBER, -LOG_ITERATION, LOG_PID, etc.. You can convert the epoch seconds to a -date from the command line with the following perl code: perl -e -'print localtime($ARGV[0])."\n";' epoch-seconds-number -

- -

The first 5 lines of the sample logfile contain header information for -all logfiles. They show the version number and URL for the library as -well as all of the settings that the library is currently using. -These settings are tuned using the dmalloc utility program. -See section Dmalloc Utility Program. The 5th line of is the process-id that -generated the logfile. -

- -

The 6th line in the above example is what causes the logfile to be -opened and the header to be written. It is a warning that tells you -that you tried to free a 0L pointer at a certain location. You can -disable these warnings by setting `ALLOW_FREE_NULL_MESSAGE' to 0 -in `settings.dist'. -

- -

Line 7 is an example of a transaction log that you get when you enable -the log-trans debug token. See section Description of the Debugging Tokens. This line -shows that a call to free was made from an unknown location. It is -unknown because the file in question did not include `dmalloc.h' -to get file/line-number information. The call to free was freeing the -pointer address 0xed310080 which we have "seen" 2 times (s2). -We saw the pointer when it was allocated and then we are seeing it -again when it was freed. Because the library is reusing pointers -(reclaiming freed memory) the seen count helps to track how many times -a pointer was used. The last part of the line shows that the pointer -to be freed was allocated by `bar.c' line 102. -

-

Lines 8-10 is the next problem that the library caught and this one is -an error. It happened 5 seconds from the start of the log -(1098918230) and at the 50th call into the library. It shows that an -allocation that had been freed then was overwritten. This may imply -that someone tried to use memory after it was freed or that there was -a loose pointer reference. The last two lines give more details about -when the error was discovered, the address of the offending pointer, -and when the pointer was previous accessed, in this case freed. To -discover where this problem is happening, you can use a debugger. -See section Using Dmalloc With a Debugger. -

3.14 Various Other Hints That May Help

- - -

One of the problems that is often seen is that a program crashes in -the libc memory code and you suspect a heap memory problem but -both dmalloc and maybe valgrind don't show any problems. One of the -big problems with debugging is that it is very difficult to do it -without effecting how the program is run. Sometimes errors are due to -subtle race conditions that are only seen when the program is running -at full speed - not slowed down by debugging code. -

-

This is especially true with threaded code which is often heavily -affected when used with dmalloc and valgrind. Older versions of -valgrid (maybe current) forced all threads into a single virtual -system by design, which often masks reentrance bugs. -

-

One way to work through these issues is to run with the library with -very few debugging flags enabled. Many memory problems are fence-post -areas so start with dmalloc checking just the fence post and error -logging enabled: -

-
 
dmalloc -d 0 -l dmalloc.log -p log-stats -p log-non-free -p check-fence -p check-funcs 
-
-

This enabled a small number of checks and should cause your program to -run at close to full speed. The library has never been optimized for -speed so some performance penalties will be felt. -

4. Dmalloc Utility Program

- - -

The dmalloc program is designed to assist in the setting of the -environment variable `DMALLOC_OPTIONS'. See section Environment Variable Name and Features. It is designed to print the shell commands necessary to make -the appropriate changes to the environment. Unfortunately, it cannot -make the changes on its own so the output from dmalloc should be sent -through the eval shell command which will do the commands. -

4.1 Using a Shell Alias with the Utility

- -

The dmalloc program is designed to assist in the setting of the -environment variable `DMALLOC_OPTIONS'. See section Environment Variable Name and Features. It is designed to print the shell commands necessary to make -the appropriate changes to the environment. Unfortunately, it cannot -make the changes on its own so the output from dmalloc should be sent -through the eval shell command which will do the commands. -

- - - - - -

With shells that have aliasing or macro capabilities: csh, bash, ksh, -tcsh, zsh, etc., setting up an alias to dmalloc to do the eval call is -recommended. Bash, ksh, and zsh users should add the following to their -`.bashrc', `.profile', or `.zshrc' file respectively -(notice the -b option for bourne shell output): -

-
 
function dmalloc { eval `command dmalloc -b $*`; }
-
-

If your shell does not support the command function then try: -

-
 
function dmalloc { eval `\dmalloc -b $*`; }
-

or -

 
function dmalloc { eval `/usr/local/bin/dmalloc -b $*`; }
-
- - - -

If you are still using csh or tcsh, you should add the following -to your `.cshrc' file (notice the -C option for c-shell -output): -

-
 
alias dmalloc 'eval `\dmalloc -C \!*`'
-
-

This allows the user to execute the dmalloc command as `dmalloc -arguments'. -

-

Users of versions of the Bourne shell (usually known as /bin/sh) that -don't have command functions will need to send the output to a temporary -file and the read it back in with the "." command: -

-
 
$  dmalloc -b arguments … > /tmp/out
-$  . /tmp/out
-
-

By the way, if you are looking for a shell, I heartily recommend trying -out zsh. It is a bourne shell written from scratch with much the same -features as tcsh without the csh crap. -

-

NOTE: After you add the alias to the file you need to log out and -log back in to have it take effect, or you can execute the above -appropriate command on the command line. If you enter dmalloc -runtime and see any output with DMALLOC_OPTIONS in it then the alias -did not work. -

4.2 How to Use the Dmalloc Program

- - -

The most basic usage for the program is `dmalloc [-bC] tag'. The -`-b' or `-C' (either but not both flags used at a time) are -for generating Bourne or C shell type commands respectively. dmalloc -will try and use the SHELL environment variable to determine -whether bourne or C shell commands should be generated but you may want -to explicitly specify the correct flag. -

-

The `tag' argument to dmalloc should match a line from the user's -runtime configuration file or should be one of the built-in tags. -See section Format of the Runtime Configuration File. If no tag is specified and no other option-commands -used, dmalloc will display the current settings of the environment -variable. It is useful to specify one of the verbose options when doing -this. -

-

To find out the usage for the debug malloc program try `dmalloc ---usage-long'. The standardized usage message that will be displayed is -one of the many features of the argv library included with this package. -

-

It is available on the web at URL http://256.com/sources/argv/. -See the documentation there for more information. -

-

Here is a detailed list of the flags that can passed to dmalloc: -

-
-
-a address
-

Set the `addr' part of the `DMALLOC_OPTIONS' variable to -address (or alternatively address:number). -

-
-
-b
-

Output Bourne shell type commands. Usually handled automagically. -

-
-
-C
-

Output C shell type commands. Usually handled automagically. -

-
-
-c
-

Clear/unset all of the settings not specified with other arguments. You -can do this automatically when you set to a new tag with the -r -option. -

-

NOTE: clear will never unset the `debug' setting. Use --d 0 or a tag to `none' to achieve this. -

-
-
-d bitmask
-

Set the `debug' part of the `DMALLOC_OPTIONS' env variable to -the bitmask value which should be in hex. This is overridden (and -unnecessary) if a tag is specified. -

-
-
-D
-

List all of the debug-tokens. Useful for finding a token to be used -with the -p or -m options. Use with -v or -V -verbose options. -

-
-
-e errno
-

Print the dmalloc error string that corresponds to the error number -errno. -

-
-
-f filename
-

Use this configuration file instead of the RC file -`$HOME/.dmallocrc'. -

-
-
-g
-

Output gdb type commands for using inside of the gdb debugger. -

-
-
-h (or --help)
-

Output a help message for the utility. -

-
-
-i number
-
-

Set the checking interval to number. If the check-heap token is -enabled, this causes the library to only check the heap every Nth time -which can significantly increase the running speed of your -program. If a problem is found, however, this limits your ability to -determine when the problem occurred. Try values of 50 or 100 initially. -

-
-
-k
-

Do not reset all of the settings when a tag is specified. This -specifically overrides the -r option and is provided here to -override -r if it has been added to the dmalloc alias. -

-
-
-l filename
-

Write the debugging output and other log-file information to the -filename. Filename can include some of the following patterns which get -expanded into strings: -

-
-
- - - - -
-
%h
-

Gets expanded into the hostname if the gethostname() function is -available. -

- - -
-
%i
-

Gets expanded into the thread-id if the library has been configure to be -used with threads. See section Using the Library with a Thread Package. See the end of the -`settings.dist' file for settings which return the thread-id and -convert it into a string. -

- - - - -
-
%p
-

Gets expanded into the process-id if the getpid() function is -available. -

- - - -
-
%t
-

Gets expanded into the time value in seconds if the time() -function is available. -

- - - - -
-
%u
-

Gets expanded into the user-id number if the getuid() function is -available. -

-
-
- -

Some examples: -

-
 
# logfile produced with pid extension:
-#   logfile.8412  or  logfile.31451
-dmalloc -l logfile.%p
-
-# hostname and time extensions:
-#   dmalloc-box1.foo.com-1055213240
-dmalloc -l dmalloc-%h-%t
-
-# if threads enabled, have thread-id extension:  log.thread32
-dmalloc -l log.thread%i
-
-
-
-L
-

Write the debug-value into the environment not in hex but by -individual debug-tokens in long form. -

-
-
-m token(s)
-

Remove (minus) the debug capabilities of token(s) from the current debug -setting or from the selected tag (or -d value). Multiple -m -options can be specified. -

- - -
-
-M limit
-

Set the memory allocation limit which will abort the program if the -total memory allocations exceed this number of bytes. The limit can -be a number with a k, m, or g at the end to indicate kilobyte, -megabyte, and gigabyte respectively. Ex: 100k, 200m, 1g. If the -limit is exceeded, this will generate an ERROR_OVER_LIMIT -error. See section Description of the Internal Error Codes. -

-
-
-n
-

Without changing the environment, output the commands resulting from the -supplied options. -

- -
-
-o times
-

Set the "lock-on" period which dictates to the threaded version of -the library to not initialize or lock the mutex lock around the library -until after a certain number of allocation calls have been made. Some -number between 2 and 30 is probably good. See the "Using With -Threads" section for more information about the operation of the -library with threads. See section Using the Library with a Thread Package. -

-
-
-p token(s)
-

Add (plus) the debug capabilities of token(s) to the current debug -setting or to the selected tag (or -d value). Multiple -p -options can be specified. -

-
-
-r
-

Remove (unset) all settings when using a tag. This is useful when you -are returning to a standard development tag and want the logfile, -address, and interval settings to be cleared automatically. If you want -this behavior by default, this can be put into the dmalloc alias. -

-
-
-R
-

Output rc shell type commands. This is not for the runtime -configuration file but for the rc shell program. -

- - -
-
-s file:line
-

Set the `start' part of the `DMALLOC_OPTIONS' env variable to -a file-name and line-number location in the source where the library -should begin more extensive heap checking. The file and line numbers -for heap transactions must be working for this option to be obeyed. -This is used if you are trying to locate a problem and you want the -extensive checking to not happen initially because it's too slow. -

- - - - - - - -
-
-S number
-

Set the `start' part of the `DMALLOC_OPTIONS' env variable to -an dmalloc mark number. The library will begin more extensive heap -checking after this number of memory transactions. If you -LOG_ITERATION enabled in your `settings.h' file then -the entries in the log file will be prepended with the number of memory -transactions that the library has handled so far. This number can be -used to delay the start of the fine grained heap checking which can be -very slow. -

- - -
-
--start-size size
-

Set the `start' part of the `DMALLOC_OPTIONS' env variable to -a number of bytes. The library will begin more extensive heap checking -after this amount of memory has been allocated by the library. This -allows you to start the slow and detailed checking of the library later -in the program execution. You can use patterns like 250m, 1g, or 102k -to mean 250 megabytes, 1 gigabyte, and 102 kilobytes respectively. -

-
-
-t
-

List all of the tags in the rc-file. Use with -v or -V -verbose options. -

-
-
-u (or --usage)
-

Output the usage information for the utility. -

-
-
-v
-

Give verbose output. Especially useful when dumping current settings or -listing all of the tags. -

-
-
-V
-

Give very verbose output for outputting even more details about -settings. -

- - - -
-
--version
-

Output the version string for the utility. Please note that -the version of the library that is installed or has been linked into -your application may be different from the utility version. -

-
-
- -

If no arguments are specified, dmalloc dumps out the current settings -that you have for the environment variable. For example: -

-
 
Debug-Flags  '0x40005c7' (runtime)
-Address      0x1f008, count = 3
-Interval     100
-Logpath      'malloc'
-Start-File   not-set
-
-

With a -v option and no arguments, dmalloc dumps out the current -settings in a verbose manner. For example: -

-
 
Debug-Flags  '0x40005c7' (runtime)
-   log-stats, log-non-free, log-bad-space, check-fence, catch-null
-Address      0x1f008, count = 10
-Interval     100
-Logpath      'malloc'
-Start-File   not-set
-
-

Here are some examples of dmalloc usage: -

-
 
# start tough debugging, check the heap every 100 times,
-# send the log information to file 'logfile'
-dmalloc high -i 100 -l logfile
-
-# find out what error code 20 is (from the logfile)
-dmalloc -e 20
-
-# cause the library to halt itself when it sees the address 0x34238
-# for the 6th time.
-dmalloc -a 0x34238:6
-
-# send the log information to file 'logfile' with the time in seconds
-# as an extension.
-dmalloc -l logfile.%t
-
-# return to the normal 'runtime' settings and clear out all
-# other settings
-dmalloc -c runtime
-
-# enable basic 'low' settings plus (-p) the logging of
-# transactions (log-trans) to file 'logfile'
-dmalloc low -p log-trans -l logfile
-
-# print out the current settings with Very-verbose output
-dmalloc -V
-
-# list the available debug malloc tokens with Very-verbose output
-dmalloc -DV
-
-# list the available tags from the rc file with verbose output
-dmalloc -tv
-

4.3 Environment Variable Name and Features

- - -

An environment variable is a variable that is part of the user's -working environment and is shared by all the programs. The -`DMALLOC_OPTIONS' variable is used by the dmalloc library to -enable or disable the memory debugging features, at runtime. -NOTE: you can also use the dmalloc_debug_setup function -to set the option string. It can be set either by hand or with the -help of the dmalloc program. See section Dmalloc Utility Program. -

- - - - - - - -

To set it by hand, Bourne shell (sh, bash, ksh, or zsh) users should use: -

-
 
DMALLOC_OPTIONS=value
-export DMALLOC_OPTIONS
-
- - - -

C shell (csh or tcsh) users need to invoke: -

-
 
setenv DMALLOC_OPTIONS value
-
-

The value in the above examples is a comma separated list of tokens each -having a corresponding value. The tokens are described below: -

-
-
debug
-
-

This should be set to a value in hexadecimal which corresponds to the -functionality token values added together. See section Description of the Debugging Tokens. For -instance, if the user wanted to enable the logging of memory -transactions (value `0x008') and wanted to check fence-post memory -(value `0x400') then `debug' should be set to `0x408' -(`0x008' + `0x400'). -

-

NOTE: You don't have to worry about remembering all the hex -values of the tokens because the dmalloc program automates the setting -of this variable especially. -

- - -

NOTE: You can also specify the debug tokens directly, separated -by commas. See section Description of the Debugging Tokens. If `debug' and the tokens are -both used, the token values will be added to the debug value. -

-
-
lockon
-
-

Set this to a number which is the "lock-on" period. This dictates -to the threaded version of the library to not initialize or lock the -mutex lock around the library until after a certain number of allocation -calls have been made. See the "Using With Threads" section for more -information about the operation of the library with threads. -See section Using the Library with a Thread Package. -

-
-
log
-
- -

Set this to a filename so that if `debug' has logging enabled, the -library can log transactions, administration information, and/or errors -to the file so memory problems and usage can be tracked. -

-

To get different logfiles for different processes, you can assign -`log' to a string with %d in it (for instance -`logfile.%d'). This will be replaced with the pid of the running -process (for instance `logfile.2451'). -

-

WARNING: it is easy to core dump any program with dmalloc, if -you send in a format with arguments other than the one %d. -

-
-
addr
-
- - -

When this is set to a hex address (taken from the dmalloc log-file for -instance) dmalloc will abort when it finds itself either allocating or -freeing that address. -

-

The address can also have an `:number' argument. For instance, if -it was set it to `0x3e45:10', the library will kill itself the 10th -time it sees address `0x3e45'. By setting the number argument to -0, the program will never stop when it sees the address. This is useful -for logging all activity on the address and makes it easier to track -down specific addresses not being freed. -

-

This works well in conjunction with the STORE_SEEN_COUNT option. -See section Tracking Down Non-Freed Memory. -

-

NOTE: dmalloc will also log all activity on this address along -with a count. -

-
-
inter
-
-

By setting this to a number X, dmalloc will only check the heap every X -times. This means a number of debugging features can be enabled while -still running the program within a finite amount of time. -

-

A setting of `100' works well with reasonably memory intensive -programs. This of course means that the library will not catch errors -exactly when they happen but possibly 100 library calls later. -

-
-
start
-
-

Set this to a number X and dmalloc will begin checking the heap after X -times. This means the intensive debugging can be started after a -certain point in a program. -

-

`start' also has the format `file:line'. For instance, if it -is set to `dmalloc_t.c:126' dmalloc will start checking the heap -after it sees a dmalloc call from the `dmalloc_t.c' file, line -number 126. If you use `dmalloc_t.c:0', with a 0 line number, then -dmalloc will start checking the heap after it sees a call from anywhere -in the `dmalloc_t.c' file. -

-

This allows the intensive debugging to be started after a certain -routine or file has been reached in the program. -

-
- -

Some examples are: -

-
 
# turn on transaction and stats logging and set
-# 'logfile' as the log-file
-setenv DMALLOC_OPTIONS log-trans,log-stats,log=logfile
-
-# enable debug flags 0x1f as well as heap-checking and
-# set the interval to be 100
-setenv DMALLOC_OPTIONS debug=0x1f,check-heap,inter=100
-
-# enable 'logfile' as the log-file, watch for
-# address '0x1234', and start checking when we see
-# file.c line 123
-setenv DMALLOC_OPTIONS log=logfile,addr=0x1234,start=file.c:123

4.4 Description of the Debugging Tokens

- - -

The below tokens and their corresponding descriptions are for the -setting of the debug library setting in the environment variable. -See section Environment Variable Name and Features. They should be specified in the user's -`.dmallocrc' file. See section Format of the Runtime Configuration File. -

-

Each token, when specified, enables a specific debugging feature. For -instance, if you have the log-stats token enabled, the library -will log general statistics to the logfile. -

-

To get this information on the fly, use dmalloc -DV. This will -print out the Debug tokens in Very-verbose mode. See section Dmalloc Utility Program. -

-
-
-
-
none
-

No debugging functionality -

- -
-
log-stats
-

Log general statistics when dmalloc_shutdown or dmalloc_log_stats is -called. -

- -
-
log-non-free
-

Log non-freed memory pointers when dmalloc_shutdown or dmalloc_log_unfreed -is called. -

- -
-
log-known
-

Log only known memory pointers that have not been freed. Pointers which -do not have file/line or return-address information will not be logged. -

- -
-
log-trans
-

Log general memory transactions (quite verbose). -

- -
-
log-admin
-

Log administrative information (quite verbose). -

- -
-
log-bad-space
-

Log actual bytes in and around bad pointers. -

- -
-
log-nonfree-space
-

Log actual bytes in non-freed pointers. -

- -
-
log-elapsed-time
-

Log elapsed-time for allocated pointers (see `conf.h'). -

- -
-
log-current-time
-

Log current-time for allocated pointers (see `conf.h'). -

- -
-
check-fence
-

Check fence-post memory areas. -

- -
-
check-heap
-

Verify heap administrative structure. -

- -
-
check-blank
-

Check to see if space that was blanked when a pointer was allocated or -when it was freed has been overwritten. If this is enabled then it -will enable free-blank and alloc-blank automatically. -

- -
-
check-funcs
-

Check the arguments of some functions (mostly string operations) looking -for bad pointers. -

- -
-
check-shutdown
-

Check all of the pointers in the heap when the program exits. -

- - - - - - - - - -
-
catch-signals
-

Shutdown the library automatically on SIGHUP, SIGINT, or SIGTERM. This -will cause the library to dump its statistics (if requested) when you -press control-c on the program (for example). -

- -
-
realloc-copy
-

Always copy data to a new pointer when realloc. -

- - - - - - - - - - - - - - -
-
free-blank
-

Write special "dmalloc-free" byte (hexadecimal 0xdf, octal -0337, decimal 223) into space when it is freed. You can -set this to be something else in the `settings.dist' file. This -ensures that your program is not using memory after it has been freed. -You can check to see if areas have been improperly overwritten with -the check-blank token. If the free space has been overwritten, -then ERROR_FREE_OVERWRITTEN is triggered. See section Description of the Internal Error Codes. -

- - - -
-
error-abort
-

Abort the program (and dump core) on errors. See error-dump -below. See section Generating a Core File on Errors. -

- - - - - - - - - - - - - -
-
alloc-blank
-

Write special "dmalloc-alloc" byte (hexadecimal 0xda, octal -0332, decimal 218) into space when it is allocated. You -can set this to be something else in the `settings.dist' file. -If you are not using calloc this will overwrite the user space -with the special bytes ensuring that your program is initializing its -dynamic memory appropriately. Also, if you ask for 35 bytes and the -library has to give you a block of 64 because of rounding issues, it -will overwrite the extra memory with the special byte. You can then -check to see if the extra areas have been improperly overwritten by -enabling the check-blank token. -

- -
-
print-messages
-

Log any errors and messages to the screen via standard-error. -

- - - -
-
catch-null
-

Abort the program immediately if the library fails to get more heap -space from the heap allocation routine mmap or sbrk. -

- -
-
never-reuse
-

Have the heap never use space that has been used before and freed. -See section Tracking Down Non-Freed Memory. WARNING: This should be used with caution -since you may run out of heap space. -

- - - -
-
error-dump
-

Dump core on error and then continue. Later core dumps overwrite -earlier ones if the program encounters more than one error. See -error-abort above. See section Generating a Core File on Errors. -

-

NOTE: This will only work if your system supports the fork -system call and the configuration utility was able to fork without going -recursive. -

- - - - -
-
error-free-null
-

By default the library will not generate an error when a program tries -to free a NULL pointer. By enabling this token, you can change this -behavior so an error is reported. See also the ALLOW_FREE_NULL and -ALLOW_FREE_NULL_MESSAGE settings in the `settings.h' file to change -the default behavior. -

-

4.5 Format of the Runtime Configuration File

- - -

By using a RC File (or runtime configuration file) you can alias -tags to combinations of debug tokens. See section Description of the Debugging Tokens. -

-

NOTE: For beginning users, the dmalloc program has a couple of -tags built into it so it is not necessary for you to setup a RC file: -

-
-
- -
-
runtime
-

Enables basic runtime tests including fence-post checking, null handling, -and logging of any errors. -

- - -
-
low
-

Runtime settings plus minimal checking of heap structures and -overwriting of allocated and freed space. -

- - -
-
medium
-

Low settings plus checking of all heap structures on each memory call, -always relocates block on realloc, and aborts on errors. You may want -to use -i option to the dmalloc utility. See section Dmalloc Utility Program. -

- - -
-
high
-

Medium settings plus checking of overwritten freed and allocated -memory and checking of arguments to a number of common functions. You -may want to use -i option to the dmalloc utility. See section Dmalloc Utility Program. -

-
-
- -

For expert users, a sample `dmallocrc' file has been provided but -you are encouraged to roll your own combinations. The name of default -rc-file is `$HOME/.dmallocrc'. The `$HOME' environment -variable should be set by the system to point to your home-directory. -

-

The file should contain lines in the general form of: -

-
 
tag     token1, token2, …
-
-

`tag' is to be matched with the tag argument passed to the dmalloc -program, while `token1, token2, …' are debug capability -tokens. See section Dmalloc Utility Program, Description of the Debugging Tokens. -

-

A line can be finished with a `\' meaning it continues onto the -next line. Lines beginning with `#' are treated as comments and -are ignored along with empty lines. -

-

Here is an example of a `.dmallocrc' file: -

-
 
#
-# Dmalloc runtime configuration file for the debug malloc library
-#
-
-# no debugging
-none    none
-
-# basic debugging
-debug1  log-stats, log-non-free, check-fence
-
-# more logging and some heap checking
-debug2  log-stats, log-non-free, log-trans, \
-        check-fence, check-heap, error-abort
-
-# good utilities
-debug3  log-stats, log-non-free, log-trans, \
-        log-admin, check-fence, check-heap, realloc-copy, \
-        free-blank, error-abort
-
-…
-
-

For example, with the above file installed, you can type dmalloc -debug1 after setting up your shell alias. See section Dmalloc Utility Program. -This enables the logging of statistics, the logging of non-freed memory, -and the checking of fence-post memory areas. -

-

Enter dmalloc none to disable all memory debugging features. -

5.1 Definition of Terms and other Information

- - -

Here are a couple definitions and other information for those interested -in "picking the brain" of the library. The code is a little ugly here -and there and it conforms to the Gray-Watson handbook of coding -standards only. -

-
-
bblock
-

basic block containing 2 ^ BASIC_BLOCK bytes of info -

-
-
bblock_adm
-

administration for a set of basic blocks -

-
-
dblock
-

divided block containing some base 2 number of blocks smaller than a -basic block. -

-
-
dblock_adm
-

administration for a set of divided blocks -

-

5.2 General Compatibility Concerns

- - -
    -
  • -Realloc() backwards compatibility with being able to realloc from the -last freed block is not supported. The author is interested to -know who is using this (cough, cough) feature and for what reason. - - - -
  • -Realloc() of a NULL pointer is supported in which case the library -will just make a call to malloc(). This can be disabled with the help -of the ALLOW_REALLOC_NULL manual compilation option in the -`settings.h' file to adjust the library's default behavior. - - - -
  • -Some systems allow free(0) to not be an error for some reason. Since -0 is not a valid address returned by the malloc call, it is debatable -that this should be allowed. See `settings.h' for the -ALLOW_FREE_NULL manual compilation option to adjust the -library's default behavior. - -
  • -Aside from possibly being slower than the system's memory allocation -functions, the library should be fully compatible with the standard -memory routines. If this is not the case, please bring this to -my attention. -
- - -

-

5.3 Issues Important for Porting the Library

- - -

General portability issues center around: -

-
    -
  • - - - - -mmap, sbrk, or compatible function usages. The library does support a -preallocated memory chunk heap. See the INTERNAL_MEMORY_SPACE -define in the `settings.dist' file. - -
  • - -The locating of the caller's address from the dmalloc functions. -This is useful in locating problems from dmalloc functions called from C -files which did not include `dmalloc.h': C library calls for -instance. - - -

    See `return.h' for the available architecture/compiler -combinations. You may want to examine the assembly code from gcc (GNUs -superior c-compiler) version 2+ being run on the following code. It -should give you a good start on building a hack for your box. -

    -
     
    static char * x;
-
-a()
-{
-        x = __builtin_return_address(0);
-}
-
-main()
-{
-        a();
-}

6. Some Solutions to Common Problems

- - -

This section provides some answers to some common problems and -questions. Please send me mail with any additions to -this list - either problems you are still having or tips that you would -like to pass on. -

-

When diagnosing a problem, if possible, always make sure you are running -the most up to date version of Dmalloc available from the home page at -URL http://dmalloc.com/. Problems are often fixed and a new -release can be published before people encounter them. -

-
-
- - - - - -
-
`Why does my program run so slow?'
-
- -

This library has never been (and maybe never will be) optimized for -space nor speed. Some of its features make it unable to use some of -the organizational methods of other more efficient heap libraries. -

-

If you have the check-heap token enabled, your program might -run slow or seem to hang. This is because by default, the library -will run a full check of the heap with every memory allocation or -free. You can have the library check itself less frequently by using -the -i option to the dmalloc utility. See section Dmalloc Utility Program. -If you are using the high token and you need your program to run -faster, try the medium or low tokens which don't check as -many heap features and so run faster although they will not catch as -many problems. See section Format of the Runtime Configuration File. -

- - -
-
`Why was a log-file not produced after I ran my program?'
-
-

This could be caused by a number of different problems. -

-
    -
  1. Are you sure you followed all of the items in the "Getting Started" -section? Please review them if there is any doubt. See section Getting Started with the Library. - - - - - -
  2. Use the env or printenv commands to make sure that -the `DMALLOC_OPTIONS' variable is set in your exported environment. -See section Environment Variable Name and Features. - - - - -
  3. Make sure that your program has been compiled correctly with the -dmalloc library. The ident program should show chunk.c and other -dmalloc files compiled into your program. You can also do strings --a your-program | grep chunk.c and look for something like `$Id: -chunk.c,v 1.152 1999/08/25 12:37:01 gray Exp $' with different versions -and date information. If this doesn't show up then chances are dmalloc -was not linked into your program. - -
  4. If your program changes its working directory, it may write the -dmalloc log-file somewhere else in the filesystem. You will need to -check both where the program was started and to where it might change -directory. - -
  5. The logfile is only produced when dmalloc_shutdown() is -called. By default it will be called when exit() gets called. -If you are running your program and press Control-C under Unix -the program will stop immediately and dmalloc_shutdown() will -not get called. You can either setup a signal handler for -SIGINTR and call exit yourself, or you can enable the -catch-signals token. See section Description of the Debugging Tokens. - -
  6. If your program is segfaulting or otherwise crashing when it exits, the -exit() routine may not being called. You will have to resolve -these issues so the dmalloc library can gracefully exit and write its -log file. - -
  7. You may want to call dmalloc_log_stats() and -dmalloc_log_unfreed() (or dmalloc_log_changed()) directly -to have the library write its log file. Some system modules may not -have shutdown if you call this before exit() so extra unfreed -memory may be reported. - -
- -
-
`I don't see any information about my non-freed (leaked) memory?'
-
-

The library will not (by default) report on "unknown" non-freed -memory. Unknown means memory that does not have associated file and -line information. -

-

This will be necessary if you are not -including `dmalloc.h' in all of your C files or if you are -interested in tracking leaks in system functions. -

-
-
`Dmalloc is returning the error "malloc library has gone recursive"'
-
-

This most likely indicates that you are using the Dmalloc library within -a threaded application and two threads are trying to use the dmalloc -library at once. Please see the section of the manual about threads for -more information about properly configuring the library. See section Using the Library with a Thread Package. -

-

If you are not using threads, then your program could have caught a -signal while within Dmalloc, which then in turn called a memory -allocation routine. It is unwise to allocate memory on the heap in most -signal handlers. Lastly, some functions called by the library may call -memory routines that it does not anticipate. If you think this the -case, please report the problem and include a stack trace, operating -system version/type, and the version of Dmalloc you are using. -

You will need to -ungzip and then untar the release file into your source work -directory. You may have to rename the file to @file{.tar.gz} to get -some old zip programs to handle the file correctly. - -@cindex settings.dist file - -@item You may want to edit or at least review the settings in -@file{settings.dist} to tune specific features of the library. The -@file{configure} script will copy this file to @file{settings.h} which -is where you should be adding per-architecture settings. - -@cindex configure script -@cindex --disable-cxx -@cindex --enable-threads -@cindex --enable-shlib -@cindex conf.h file - -@item Type @kbd{sh ./configure} to configure the library. You may want -to first examine the @file{config.help} file for some information about -configure. You may want to use the @kbd{--disable-cxx} option if you do -not want the Makefile to build the C++ version of dmalloc. You may want -to use the @kbd{--enable-threads} option to build the threaded version -of dmalloc. You may want to use the @kbd{--enable-shlib} option to -build the shared versions of the dmalloc libraries. @kbd{sh ./configure ---help} lists the available options to configure. Configure should -generate the @file{Makefile} and configuration files automatically. - -@item You may want to examine the @file{Makefile} and @file{conf.h} files -created by configure to make sure it did its job correctly. - -@cindex settings.h file - -@item You might want to tune the settings in @file{settings.h} file to -tune the library to the local architecture. This file contains relevant -settings if you are using pthreads or another thread library. -@xref{Using With Threads}. The @file{configure} script created this -file from the @file{settings.dist} file. Any permanent changes to these -settings should made to the @file{settings.dist} file. You then can run -@file{config.status} to re-create the @file{settings.h} file. - -@cindex DMALLOC_SIZE option - -@item The @code{DMALLOC_SIZE} variable gets auto-configured in -@file{dmalloc.h.2} but it may not generate correct settings for all -systems. You may have to alter the definitions in this file to get -things to stop complaining when you go to compile about the size -arguments to malloc routines. Comments on this please. - -@item Typing @kbd{make} should be enough to build @file{libdmalloc.a}, -and @file{dmalloc} program. If it does not work, please see if there -are any notes in the contrib directory about your system-type. If not -and you figure your problem out, please send me some notes so future -users can profit from your experiences. - -@cindex USE_RETURN_MACROS conf.h option - -@emph{NOTE}: You may experience some errors compiling some of the -@file{return.h} assembly macros which attempt to determine the callers -address for logging purposes. @xref{Portability}. You may want to -first try disabling any compiler optimization flags. If this doesn't -work then you may need to disable the @samp{USE_RETURN_MACROS} -variable in the @file{settings.h} file. - -@cindex ANSI-C compiler - -@emph{NOTE}: The code is dependent on an ANSI-C compiler. If the -configure script gives the @samp{WARNING} that you do not have an ANSI-C -compiler, you may still be able to add some sort of option to your -compiler to make it ANSI. If there such is an option, please send it to -the author so it can be added to the configure script. - -@item If you use threads and did not add the @kbd{--enable-threads} -argument to configure, typing @kbd{make threads} should be enough to -build @file{libdmallocth.a} which is the threaded version of the -library. This may or may not work depending on the configuration -scripts ability to detect your local thread functionality. Feel free to -send me mail with improvements. - -See the section of the manual on threads for more information about -the operation of the library with your threaded program. @xref{Using -With Threads}. - -@item If you have a C++ compiler installed, the library should have -automatically built @file{libdmallocxx.a} which is the C++ version of -the library. If it was not done automatically, you can build it by -typing @kbd{make cxx}. You should link this library into your C++ -programs instead of @file{libdmalloc.a}. See the @file{dmallocc.cc} C++ -file which contains basic code to overload the @code{new}, @code{new[]}, -@code{delete}, and @code{delete[]} C++ operators. My apologies on the -minimal C++ support. I am still living in a mostly C world. Any help -improving this interface without sacrificing portability would be -appreciated. - -@cindex testing the library -@cindex dmalloc_t test program - -@item Typing @kbd{make light} should build and run the @file{dmalloc_t} test -program through a set of light trials. By default this will execute -@file{dmalloc_t} 5 times -- each time will execute 10,000 malloc -operations in a very random manner. Anal folks can type @kbd{make -heavy} to up the ante. Use @kbd{dmalloc_t --usage} for the list of all -@file{dmalloc_t} options. - -@item Typing @kbd{make install} should install the @file{libdmalloc.a} -library in @file{/usr/local/lib}, the @file{dmalloc.h} include file in -@file{/usr/local/include}, and the @file{dmalloc} utility in -@file{/usr/local/bin}. You may also want to type @kbd{make installth} -to install the thread library into place and/or @kbd{make installcc} to -install the C++ library into place. - -You may have specified a @samp{--prefix=PATH} option to configure in -which case @samp{/usr/local} will have been replaced with @samp{PATH}. - -@end enumerate - -See the ``Getting Started'' section to get up and running with the -library. @xref{Getting Started}. - -@c -------------------------------- - -@node Getting Started, Allocation Basics, Installation, Overview -@section Getting Started with the Library - -@cindex quick start -@cindex getting started -@cindex jump start -@cindex how to begin -@cindex where to begin -@cindex beginning - -This section should give you a quick idea on how to get going. -Basically, you need to do the following things to make use of the -library: - -@enumerate - -@item Make sure you have downloaded the latest version of the library -available from the home page at URL @uref{http://dmalloc.com/}. - -@item Follow the installation instructions on how to configure, -make, and install the library (i.e. type: @kbd{make install}). -@xref{Installation}. - -@cindex automatic shutdown -@cindex shutdown, automatic -@cindex on_exit -@cindex atexit -@cindex destructor - -@item You need to make sure that the library configuration and -build process above was able to locate one of the @code{on_exit} -function, @code{atexit} function, or had compiler destructor support. -If one of these functions or support is available then the dmalloc -library should be able to automatically shut itself down when the -program exits. This causes the memory statistics and unfreed -information to be dumped to the log file. However, if your system has -none of the above, then you will need to call @code{dmalloc_shutdown} -yourself before your program exits. - -@cindex alias, shell -@cindex bash shell -@cindex ksh shell -@cindex zsh shell - -@item To get the dmalloc utility to work you need to add an alias for -dmalloc to your shell's runtime configuration file if supported. The -idea is to have the shell capture the dmalloc program's output and -adjust the environment. - -After you add the alias to the shell config file you need to log out -and log back in to have it take effect, or you can execute the -appropriate command below on the command line directly. After you -setup the alias, if you enter @kbd{dmalloc runtime} and see any output -with DMALLOC_OPTIONS in it then the alias did not take effect. - -Bash, ksh, and zsh (@uref{http://www.zsh.org/}) users should add the -following to their @file{.bashrc}, @file{.profile}, or @file{.zshrc} -file respectively (notice the @kbd{-b} option for bourne shell -output): - -@example -function dmalloc @{ eval `command dmalloc -b $*`; @} -@end example - -If your shell does not support the @code{command} function then try: - -@example -function dmalloc @{ eval `\dmalloc -b $*`; @} -@end example -or -@example -function dmalloc @{ eval `/usr/local/bin/dmalloc -b $*`; @} -@end example - -@cindex csh shell -@cindex tcsh shell - -If you are still using csh or tcsh, you should add the following to -your @file{.cshrc} file (notice the @kbd{-C} option for c-shell -output): - -@example -alias dmalloc 'eval `\dmalloc -C \!*`' -@end example - -@cindex rc shell - -If you are using rc shell, you should add the following to your -@file{.rcrc} file (notice the @kbd{-R} option for rc-shell output): - -@example -fn dmalloc @{eval `@{/usr/local/bin/dmalloc $*@}@} -@end example - -@item Although not necessary, you may want to include @file{dmalloc.h} -in your C files and recompile. This will allow the library to report -the file/line numbers of calls that generate problems. @xref{Allocation -Macros}. It should be inserted at the @emph{bottom} of your include -files as to not conflict with wother includes. You may want to ifdef it -as well and compile with @kbd{cc -DDMALLOC @dots{}}: - -@example -/* other includes above ^^^ */ - -#ifdef DMALLOC -#include "dmalloc.h" -#endif -@end example - -@cindex DMALLOC_FUNC_CHECK -@item Another optional task is to compile all of your source with the -@file{dmalloc.h} with the @code{DMALLOC_FUNC_CHECK} compilation flag. -This willallow the library to check all of the arguments of a number -of common string and utility routines. @xref{Argument Checking}. - -@example -cc -DDMALLOC -DDMALLOC_FUNC_CHECK file.c -@end example - -@item Link the dmalloc library into your program. The dmalloc library -should probably be placed at or near the end of the library list. - -@item Enable the debugging features by typing @kbd{dmalloc -l logfile --i 100 low} (for example). You should not see any messages printed by -the dmalloc utility (see NOTE below). This will: - -@itemize @bullet - -@item Set the malloc logfile name to @file{logfile} (@kbd{-l logfile}). -For programs which change directories, you may want to specify the -full path to your logfile. - -@item Have the library check itself every 100 iterations (@kbd{-i 100}). -This controls how fast your program will run. Larger numbers check -the heap less and so it will run faster. Lower numbers will be more -likely to catch memory problems. - -@item Enable a number of debug features (@kbd{low}). You can -also try @kbd{runtime} for minimal checking or @kbd{medium} or -@kbd{high} for more extensive heap verification. - -@item By default, the low, medium, and high values enable the -@code{error-abort} token which will cause the library to abort and -usually dump core immediately upon seeing an error. @xref{Dumping -Core}. You can disable this feature by entering @kbd{dmalloc -m -error-abort} (-m for minus) to remove the @code{error-abort} token and -your program will just log errors and continue. - -@end itemize - -@kbd{dmalloc --usage} will provide verbose usage info for the dmalloc -program. @xref{Dmalloc Program}. - -You may also want to install the @file{dmallocrc} file in your home -directory as @file{.dmallocrc}. This allows you to add your own -combination of debug tokens. @xref{RC File}. - -@emph{NOTE}: The output from the dmalloc utility should be captured by -your shell. If you see a bunch of stuff which includes the string -@code{DMALLOC_OPTIONS} then the alias you should have created above is -not working and he environmental variables are not being set. Make -sure you've logged out and back in to have the alias take effect. - -@item Run your program, examine the logfile that should have been -created by @code{dmalloc_shutdown}, and use its information to help -debug your program. - -@end enumerate - -@c -------------------------------- - -@node Allocation Basics, Features, Getting Started, Overview -@section Basic Description of Terms and Functions - -@cindex allocation basics -@cindex basic allocation information - -@menu -* Basic Definitions:: General memory terms and concepts. -* Malloc Functions:: Functionality supported by all malloc libs. -@end menu - -@c -------------------------------- - -@node Basic Definitions, Malloc Functions, Allocation Basics, Allocation Basics -@subsection General Memory Terms and Concepts - -@cindex basic definitions -@cindex memory definitions - -Any program can be divided into 2 logical parts: text and data. Text is -the actual program code in machine-readable format and data is the -information that the text operates on when it is executing. The data, -in turn, can be divided into 3 logical parts according to where it is -stored: @dfn{static}, @dfn{stack}, and @dfn{heap}. - -@cindex static memory - -Static data is the information whose storage space is compiled into the -program. - -@example -/* global variables are allocated as static data */ -int numbers[10]; - -main() -@{ - @dots{} -@} -@end example - -@cindex stack memory - -Stack data is data allocated at runtime to hold information used inside -of functions. This data is managed by the system in the space called -stack space. - -@example -void foo() -@{ - /* this local variable is stored on the stack */ - float total; - @dots{} -@} - -main() -@{ - foo(); -@} -@end example - -@cindex heap memory - -Heap data is also allocated at runtime and provides a programmer with -dynamic memory capabilities. - -@example -main() -@{ - /* the address is stored on the stack */ - char * string; - @dots{} - - /* - * Allocate a string of 10 bytes on the heap. Store the - * address in string which is on the stack. - */ - string = (char *)malloc(10); - @dots{} - - /* de-allocate the heap memory now that we're done with it */ - (void)free(string); - @dots{} -@} -@end example - -It is the heap data that is managed by this library. - -Although the above is an example of how to use the malloc and free -commands, it is not a good example of why using the heap for runtime -storage is useful. - -Consider this: You write a program that reads a file into memory, -processes it, and displays results. You would like to handle files with -arbitrary size (from 10 bytes to 1.2 megabytes and more). One problem, -however, is that the entire file must be in memory at one time to do the -calculations. You don't want to have to allocate 1.2 megabytes when you -might only be reading in a 10 byte file because it is wasteful of system -resources. Also, you are worried that your program might have to handle -files of more than 1.2 megabytes. - -A solution: first check out the file's size and then, using the -heap-allocation routines, get enough storage to read the entire file -into memory. The program will only be using the system resources -necessary for the job and you will be guaranteed that your program can -handle any sized file. - -@c -------------------------------- - -@node Malloc Functions,, Basic Definitions, Allocation Basics -@subsection Functionality Supported by All Malloc Libraries - -@cindex malloc functions - -All malloc libraries support 4 basic memory allocation commands. These -include @dfn{malloc}, @dfn{calloc}, @dfn{realloc}, and @dfn{free}. For -more information about their capabilities, check your system's manual -pages -- in unix, do a @code{man 3 malloc}. - -@cindex malloc -@deftypefun void *malloc ( unsigned int @var{size} ) - -Usage: @code{pnt = (type *)malloc(size)} - -The malloc routine is the basic memory allocation routine. It allocates -an area of @code{size} bytes. It will return a pointer to the space -requested. - -@end deftypefun -@deftypefun void *calloc ( unsigned int @var{number}, unsigned int@var{size} ) -@cindex calloc -@cindex Allocation of zeros -@cindex zeros, allocation of - -Usage: @code{pnt = (type *)calloc(number, size)} - -The calloc routine allocates a certain @code{number} of items, each of -@code{size} bytes, and returns a pointer to the space. It is -appropriate to pass in a @code{sizeof(type)} value as the size argument. - -Also, calloc nulls the space that it returns, assuring that the memory -is all zeros. - -@end deftypefun -@deftypefun void *realloc ( void *@var{old_pnt}, unsigned int @var{new_size} ) -@cindex realloc - -Usage: @code{new_pnt = (type *)realloc(old_pnt, new_size)} - -The realloc function expands or shrinks the memory allocation in -@code{old_pnt} to @code{new_size} number of bytes. Realloc copies as -much of the information from @code{old_pnt} as it can into the -@code{new_pnt} space it returns, up to @code{new_size} bytes. If there -is a problem allocating this memory, 0L will be returned. - -If the @code{old_pnt} is 0L then realloc will do the equivalent of a -@code{malloc(new_size)}. If @code{new_size} is 0 and @code{old_pnt} is -not 0L, then it will do the equivalent of @code{free(old_pnt)} and will -return 0L. - -@end deftypefun -@deftypefun void free ( void *@var{pnt} ) -@cindex free - -Usage: @code{free(pnt)} - -The free routine releases allocation in @code{pnt} which was returned by -malloc, calloc, or realloc back to the heap. This allows other parts of -the program to re-use memory that is not needed anymore. It guarantees -that the process does not grow too big and swallow a large portion of -the system resources. - -@end deftypefun - -@emph{WARNING}: there is a quite common myth that all of the space that -is returned by malloc libraries has already been cleared. @emph{Only} -the @code{calloc} routine will zero the memory space it returns. - -@c -------------------------------- - -@node Features, How It Works, Allocation Basics, Overview -@section General Features of the Library - -@cindex features - -The debugging features that are available in this debug malloc library -can be divided into a couple basic classifications: - -@table @asis -@item file and line number information -@cindex file/line numbers -@cindex cpp -One of the nice things about a good debugger is its ability to provide -the file and line number of an offending piece of code. This library -attempts to give this functionality with the help of @dfn{cpp}, the C -preprocessor. @xref{Allocation Macros}. - -@item return-address information -@cindex return-address -To debug calls to the library from external sources (i.e. those files -that could not use the allocation macros), some facilities have been -provided to supply the caller's address. This address, with the help of -a debugger, can help you locate the source of a problem. @xref{Return -Address}. - -@item fence-post (i.e. bounds) checking -@cindex fence-post checking -@cindex bounds checking -@cindex checking bounds -@dfn{Fence-post} memory is the area immediately above or below memory -allocations. It is all too easy to write code that accesses above or -below an allocation -- especially when dealing with arrays or strings. -The library can write special values in the areas around every -allocation so it will notice when these areas have been overwritten. -@xref{Fence-Post Overruns}. - -@emph{NOTE}: The library cannot notice when the program @emph{reads} -from these areas, only when it writes values. Also, fence-post checking -will increase the amount of memory the program allocates. - -@item heap-constancy verification -@cindex constancy verification -The administration of the library is reasonably complex. If any of the -heap-maintenance information is corrupted, the program will either crash -or give unpredictable results. - -By enabling heap-consistency checking, the library will run through its -administrative structures to make sure all is in order. This will mean -that problems will be caught faster and diagnosed better. - -The drawback of this is, of course, that the library often takes quite a -long time to do this. It is suitable to enable this only during -development and debugging sessions. - -@emph{NOTE}: the heap checking routines cannot guarantee that the tests -will not cause a segmentation-fault if the heap administration -structures are properly (or improperly if you will) overwritten. In -other words, the tests will verify that everything is okay but may not -inform the user of problems in a graceful manner. - -@item logging statistics -@cindex logging statistics -@cindex statistics -@cindex memory leaks -@cindex leaking memory -One of the reasons why the debug malloc library was initially developed -was to track programs' memory usage -- specifically to locate -@dfn{memory leaks} which are places where allocated memory is never -getting freed. @xref{Memory Leaks}. - -The library has a number of logging capabilities that can track un-freed -memory pointers as well as runtime memory usage, memory transactions, -administrative actions, and final statistics. - -@item examining freed memory -@cindex freed memory -@cindex freed memory -Another common problem happens when a program frees a memory pointer but -goes on to use it again by mistake. This can lead to mysterious crashes -and unexplained problems. - -To combat this, the library can write special values into a block of -memory after it has been freed. This serves two purposes: it will make -sure that the program will get garbage data if it trying to access the -area again, and it will allow the library to verify the area later for -signs of overwriting. -@end table - -If any of the above debugging features detect an error, the library will -try to recover. If logging is enabled then an error will be logged with -as much information as possible. - -The error messages that the library displays are designed to give the -most information for developers. If the error message is not -understood, then it is most likely just trying to indicate that a part -of the heap has been corrupted. - -@cindex dump core -@cindex core dump -The library can be configured to quit immediately when an error is -detected and to dump a core file or memory-image. This can be -examined with a debugger to determine the source of the problem. The -library can either stop after dumping core or continue running. -@xref{Dumping Core}. - -@cindex system memory problems -@cindex memory problems in system functions -@emph{NOTE}: do not be surprised if the library catches problems with -your system's routines. It took me hours to finally come to the -conclusion that the localtime call, included in SunOS release 4.1, -overwrites one of its fence-post markers. - -@c -------------------------------- - -@node How It Works,, Features, Overview -@section How the Library Checks Your Program - -This is one of the newer sections of the library implying that it is -incomplete. If you have any questions or issues that you'd like to see -handled here, please let me know. - -The dmalloc library replaces the heap library calls normally found in -your system libraries with its own versions. When you make a call to -malloc (for example), you are calling dmalloc's version of the memory -allocation function. When you allocate memory with these functions, the -dmalloc library keeps track of a number of pieces of debugging -information about your pointer including: where it was allocated, -exactly how much memory was requested, when the call was made, etc.. -This information can then be verified when the pointer is freed or -reallocated and the details can be logged on any errors. - -Whenever you reallocate or free a memory address, the dmalloc library -always performs a number of checks on the pointer to make sure that it -is valid and has not been corrupted. You can configure the library to -perform additional checks such as detected fence-post writing. The -library can also be configured to overwrite memory with non-zeros (only -if calloc is not called) when it is allocated and erase the memory when -the pointers are freed. - -@cindex check-heap -In addition to per-pointer checks, you can configure the library to -perform complete heap checks. These complete checks verify all -internal heap structures and include walking all of the known -allocated pointers to verify each one in turn. You need this level of -checking to find random pointers in your program which got corrupted -but that won't be freed for a while. To turn on these checks, you -will need to enable the @code{check-heap} debug token. @xref{Debug -Tokens}. By default this will cause the heap to be fully checked each -and every time dmalloc is called whether it is a malloc, free, -realloc, or another dmalloc overloaded function. - -Performing a full heap check can take a good bit of CPU and it may be -that you will want to run it sporadically. This can be accomplished in -a couple different ways including the '-i' interval argument to the -dmalloc utility. @xref{Dmalloc Program}. This will cause the check to -be run every N-th time. For instance, 'dmalloc -i 3' will cause the -heap to be checked before every 3rd call to a memory function. Values -of 100 or even 1000 for high memory usage programs are more useful than -smaller ones. - -@cindex LOG_ITERATION_COUNT -@cindex iteration count -@cindex memory transaction count -You can also cause the program to start doing detailed heap checking -after a certain point. For instance, with 'dmalloc -s 1000' option, you -can tell the dmalloc library to enable the heap checks after the 1000th -memory call. Examine the dmalloc log file produced and use the -iteration count if you have @code{LOG_ITERATION_COUNT} enabled in your -@file{settings.h} file. - -The start option can also have the format @samp{file:line}. For -instance, if it is set to @samp{dmalloc_t.c:126}, dmalloc will start -checking the heap after it sees a dmalloc call from the -@file{dmalloc_t.c} file, line number 126. If you use -@samp{dmalloc_t.c:0}, with a 0 line number, then dmalloc will start -checking the heap after it sees a call from anywhere in the -@file{dmalloc_t.c} file. - -@c ---------------------------------------------------------------------------- - -@node Programming, Dmalloc Program, Overview, Top -@chapter How to Program with the Library - -@cindex programming - -@menu -* Allocation Macros:: Macros providing file and line information. -* Return Address:: Getting caller address information. -* Argument Checking:: Checking of function arguments. -* Dumping Core:: Generating a core file on errors for debugging. -* Extensions:: Additional non-standard routines. -* Error Codes:: Description of the internal error numbers. -* Disabling the Library:: How to disable the library. -* Using With C++:: Using the library with C++. -* Using With a Debugger:: Using a debugger with the library. -* Using With Threads:: Using the library with a thread package. -* Using With Cygwin:: Using the library with Cygwin environment. -* Debugging A Server:: Debugging memory in a server or cgi-bin process. -* Logfile Details:: Explanation of the Logfile Output. -* Other Hints:: Various other hints that may help. -@end menu - -@c -------------------------------- - -@node Allocation Macros, Return Address, Programming, Programming -@section Macros Providing File and Line Information - -@cindex allocation macros -@cindex macros, allocation -@cindex dmalloc.h file - -By including @file{dmalloc.h} in your C files, your calls to malloc, -calloc, realloc, recalloc, memalign, valloc, strdup, and free are -replaced with calls to _dmalloc_malloc, _dmalloc_realloc, and -_dmalloc_free with various flags. Additionally the library replaces -calls to xmalloc, xcalloc, xrealloc, xrecalloc, xmemalign, xvalloc, -xstrdup, and xfree with associated calls. - -These macros use the c-preprocessor @code{__FILE__} and @code{__LINE__} -macros which get replaced at compilation time with the current file and -line-number of the source code in question. The routines use this -information to produce verbose reports on memory problems. - -@example -not freed: '0x38410' (22 bytes) from 'dmalloc_t.c:92' -@end example - -This line from a log file shows that memory was not freed from file -@file{dmalloc_t.c} line 92. @xref{Memory Leaks}. - -@cindex recalloc -@cindex memalign -@cindex valloc -@cindex strdup - -You may notice some non standard memory allocation functions in the -above list. Recalloc is a routine like realloc that reallocates -previously allocated memory to a new size. If the new memory size is -larger than the old, recalloc initializes the new space to all zeros. -This may or may not be supported natively by your operating system. -Memalign is like malloc but should insure that the returned pointer is -aligned to a certain number of specified bytes. Currently, the memalign -function is not supported by the library. It defaults to returning -possibly non-aligned memory for alignment values less than a block-size. -Valloc is like malloc but insures that the returned pointer will be -aligned to a page boundary. This may or may not be supported natively -by your operating system but is fully supported by the library. Strdup -is a string duplicating routine which takes in a null terminated string -pointer and returns an allocated copy of the string that will need to be -passed to free later to deallocate. - -The X versions of the standard memory functions (xmalloc, xfree, etc.) -will print out an error message to standard error and will stop if the -library is unable to allocate any additional memory. It is useful to -use these routines instead of checking everywhere in your program for -allocation routines returning NULL pointers. - -@emph{WARNING}: If you are including the @file{dmalloc.h} file in your -sources, it is recommended that it be at the end of your include file -list because dmalloc uses macros and may try to change declarations of -the malloc functions if they come after it. - -@c -------------------------------- - -@node Return Address, Argument Checking, Allocation Macros, Programming -@section Getting Caller Address Information - -@cindex caller's address -@cindex return-address -@cindex return.h file -@cindex ra - -Even though the allocation macros can provide file/line information for -some of your code, there are still modules which either you can't -include @file{dmalloc.h} (such as library routines) or you just don't -want to. You can still get information about the routines that call -dmalloc function from the return-address information. To accomplish -this, you must be using this library on one of the supported -architecture/compilers. @xref{Portability}. - -@cindex assembly hacks - -The library attempts to use some assembly hacks to get the -return-address or the address of the line that called the dmalloc -function. If you have unfreed memory that does not have associated file -and line information, you might see the following non-freed memory -messages. - -@example -not freed: '0x38410' (22 bytes) from 'ra=0xdd2c' -not freed: '0x38600' (10232 bytes) from 'ra=0x10234d' -not freed: '0x38220' (137 bytes) from 'ra=0x82cc' -@end example - -@cindex ra_info.pl -With the help of a debugger, these return-addresses (or ra) can then be -identified. I've provided a @file{ra_info.pl} perl script in the -@file{contrib/} directory with the dmalloc sources which seems to work -well with gdb. You can also use manual methods for gdb to find the -return-address location. @xref{Translate Return Addresses}. - -@c -------------------------------- - -@node Argument Checking, Dumping Core, Return Address, Programming -@section Checking of Function Arguments - -@cindex argument checking -@cindex checking arguments -@cindex DMALLOC_FUNC_CHECK flag - -One potential problem with the library and its multitude of checks and -diagnoses is that they only get performed when a dmalloc function is -called. One solution this is to include @file{dmalloc.h} and compile -your source code with the @code{DMALLOC_FUNC_CHECK} flag defined and -enable the @code{check-funcs} token. @xref{Debug Tokens}. - -@example -cc -DDMALLOC -DDMALLOC_FUNC_CHECK file.c -@end example - -@emph{NOTE}: Once you have compiled your source with DMALLOC_FUNC_CHECK -enabled, you will have to recompile with it off to disconnect the -library. @xref{Disabling the Library}. - -@emph{WARNING}: You should be sure to have @file{dmalloc.h} included at -the end of your include file list because dmalloc uses macros and may -try to change declarations of the checked functions if they come after -it. - -When this is defined dmalloc will override a number of functions and -will insert a routine which knows how to check its own arguments and -then call the real function. Dmalloc can check such functions as -@code{bcopy}, @code{index}, @code{strcat}, and @code{strcasecmp}. For -the full list see the end of @file{dmalloc.h}. - -When you call @code{strlen}, for instance, dmalloc will make sure the -string argument's fence-post areas have not been overwritten, its file -and line number locations are good, etc. With @code{bcopy}, dmalloc -will make sure that the destination string has enough space to store the -number of bytes specified. - -For all of the arguments checked, if the pointer is not in the heap then -it is ignored since dmalloc does not know anything about it. - -@c -------------------------------- - -@node Dumping Core, Extensions, Argument Checking, Programming -@section Generating a Core File on Errors - -@cindex dump core -@cindex core dump -@cindex generating core dump -@cindex error-abort -@cindex error-dump -@cindex debugger - -If the @code{error-abort} debug token has been enabled, when the -library detects any problems with the heap memory, it will immediately -attempt to dump a core file. @xref{Debug Tokens}. Core files are a -complete copy of the program and it's state and can be used by a -debugger to see specifically what is going on when the error occurred. -@xref{Using With a Debugger}. By default, the low, medium, and high -arguments to the library utility enable the @code{error-abort} token. -You can disable this feature by entering @kbd{dmalloc -m error-abort} -(-m for minus) to remove the @code{error-abort} token and your program -will just log errors and continue. You can also use the -@code{error-dump} token which tries to dump core when it sees an error -but still continue running. @xref{Debug Tokens}. - -@cindex core file -@cindex program core -@cindex no core dump -@cindex core dump, none -@cindex missing core dump - -When a program dumps core, the system writes the program and all of -its memory to a file on disk usually named @file{core}. If your -program is called @file{foo} then your system may dump core as -@file{foo.core}. If you are not getting a @file{core} file, make sure -that your program has not changed to a new directory meaning that it -may have written the core file in a different location. Also insure -that your program has write privileges over the directory that it is -in otherwise it will not be able to dump a core file. Core dumps are -often security problems since they contain all program memory so -systems often block their being produced. You will want to check your -user and system's core dump size ulimit settings. - -@cindex abort -@cindex kill process -@cindex KILL_PROCESS - -The library by default uses the @code{abort} function to dump core -which may or may not work depending on your operating system. If the -following program does not dump core then this may be the problem. -See @code{KILL_PROCESS} definition in @file{settings.dist}. - -@example -main() -@{ - abort(); -@} -@end example - -If @code{abort} does work then you may want to try the following -setting in @file{settings.dist}.

In -effect your program can be doing a number of things ``at the same -time''. This allows you to take full advantage of modern operating -system scheduling and multi-processor hardware. If I've already lost -you or if any of the terminology below does not make sense, see manuals -about POSIX threads (pthreads) before going any further. O'Reilly -publishes a pretty good pthreads manual for example. - -To use dmalloc with your threaded program, you will first need to make -sure that you are linking with @file{libdmallocth.a} which is the -threaded version of the library. The support for threads in dmalloc -should be adequate for most if not all testing scenarios. It provides -support for mutex locking itself to protect against race conditions that -result in multiple simultaneous execution. One of the major problems is -that most thread libraries uses malloc themselves. Since all of -dmalloc's initialization happens when a call to malloc is made, we may -be attempting to initialize or lock the mutex while the thread library -is booting up. A very bad thing since thread libraries don't expect to -recurse. - -@cindex lock on - -The solution to this problem is to have the library not initialize or -lock its mutex variable until after a certain number of allocation calls -have been completed. If the library does not wait before initializing -the locks, the thread library will probably core dump. If it waits too -long then it can't protect itself from multiple execution and it will -abort or other bad things might happen. You adjust the number of times -to wait at runtime with the @samp{lock-on} option to the dmalloc program -(for example @kbd{dmalloc -o 20}). @xref{Dmalloc Program}. Times -values between 5 and 30 are probably good although operating systems -will vary significantly. You know its too low if your program -immediately core dumps and too high if the dmalloc library says its gone -recursive although with low values, you might get either problem. - -An additional complexity is when we are initializing the lock before -mutex locking around the library. As mentioned, the initialization -itself may generate a malloc call causing the library to go recursive -and the pthread library to possibly core dump. With the THREAD_INIT_LOCK -setting defined in @file{settings.h}, you can tune how many times before -we start locking to try and initialize the mutex lock.

Unknown means memory that does not have associated file and -line information. - -This will be necessary if you are @emph{not} -including @file{dmalloc.h} in all of your C files or if you are -interested in tracking leaks in system functions. - -@item Dmalloc is returning the error "malloc library has gone recursive" - -This most likely indicates that you are using the Dmalloc library within -a threaded application and two threads are trying to use the dmalloc -library at once. Please see the section of the manual about threads for -more information about properly configuring the library. @xref{Using -With Threads}. - -If you are not using threads, then your program could have caught a -signal while within Dmalloc, which then in turn called a memory -allocation routine. It is unwise to allocate memory on the heap in most -signal handlers. Lastly, some functions called by the library may call -memory routines that it does not anticipate. If you think this the -case, please report the problem and include a stack trace, operating -system version/type, and the version of Dmalloc you are using. - -@end table - -@c -------------------------------- - -@node Index of Concepts,, Troubleshooting, Top -@unnumbered Index of Concepts - -@printindex cp -@contents - -@bye
