mcdb change log
mcdb v0.10 (2022.09.28)
- mcdb_mmap_madvise()
mcdb v0.09 (2013.11.15)
- plasma_atomic:
- C11/C++11 additions
- Sun Studio and IBM xlC inline assembly for atomics in 32-bit compile
- plasma_stdtypes: C11/C++11 alignof and alignas
- plasma_attr: attribute additions
- plasma_membar.h: Linux kernel user helpers for ARM
- plasma/plasma_spin: plasma_spin_tktlock and plasma_spin_taglock
- New plasma/* components:
- plasma/plasma_endian.h - byteorder endian conversion macros
- plasma/plasma_ident.h - portability macros for ident string
- plasma/plasma_sysconf.h - system configuration info
- plasma/plasma_test.h - basic test framework support
- plasma/t/petersons_algo.c - Peterson's algorithm for mutual exclusion
- plasma/t/plasma_atomic.t.c - plasma_atomic.[ch] tests
mcdb v0.08 (2013.06.08)
- plasma/* - portability macros for compiler and hardware micro operations
- plasma/plasma_atomic.h - atomic operations
- plasma/plasma_attr.h - code attributes
- plasma/plasma_feature.h - OS and architecture features
- plasma/plasma_membar.h - memory barriers
- plasma/plasma_spin.h - spin loop components
- plasma/plasma_stdtypes.h - standard types
- mcdb.c - minimize critical sections; mark intermediate maps
- modifications for initial port to MacOSX (Darwin)
mcdb v0.07 (2013.03.31)
- plasma/* - portability macros for compiler and hardware micro operations
- mcdb.c, nss_mcdb.c - use plasma_membar.h memory barriers for thread safety
- mcdb.c - fix race in mcdb_mmap_thread_registration()
mcdb v0.06 (2012.11.18)
- mcdb_make - fix sign extension bug preventing creation of mcdb > 4 GB
mcdb v0.05 (2012.11.16)
- extension: allow user-provided (custom) hash function (C interface only)
(mcdb creator and consumers must both use same hash function substitution)
mcdb v0.04 (2011.11.07)
- porting from Linux/glibc to other platforms (large set of changes)
- mcdb_make - mcdb_fallocate() emulates posix_fallocate()
- code_attributes.h - protect C++ from C99 restrict
- split struct spwd code to separate files nss_mcdb_authn*.[ch]
mcdb v0.03 (2011.10.23)
- extend struct mcdb to store klen, and vp (void *) for user extension data
Note: struct change is incompatible with prior releases;
do not mix code built against multiple versions of mcdb.h
- mcdb - add some sanity checks to attempt to detect incorrect API use
- mcdb_make - reliably detect No space left on device
- mcdbctl uniq - mode to remake mcdb with unique keys
- contrib/lua-mcdb extension for Lua
- contrib/ruby-mcdb extension for Ruby
- compiler and linker flags to optimize DSO (.so)
- build and test contrib/* extensions against static libmcdb.a
mcdb v0.02 (2011.09.23)
- mcdb_iter iterator interface
- mcdb_make - ~10% faster writing large mcdb on multi-core 64-bit
- mcdb_makefn - refactored some for code for reuse by extensions
- contrib/MCDB_File extension for Perl
- contrib/python-mcdb extension for Python
mcdb v0.01 (2011.08.25)
- WFM: works-for-me! (alpha)
Initial release for feedback and to get over the hurdle of initial release.
More work needs to be done testing.
