core dump

[damian123]

I have a core dump when I call the tests project, at the place where run_client_test calls cli.call.
What is the best way to setup the build environment?

try {
i = cli.call("add", 12).get(); <----- here
}
catch (const std::exception& e)
{
printf("internal catch: %s\n", e.what());
}

void* msgpack_zone_malloc_expand(msgpack_zone* zone, size_t size)
{
msgpack_zone_chunk_list* const cl = &zone->chunk_list;

size_t sz = zone->chunk_size;

while(sz < size) {
    sz *= 2;
}

msgpack_zone_chunk* chunk = (msgpack_zone_chunk*)malloc(
        sizeof(msgpack_zone_chunk) + sz);

char* ptr = ((char*)chunk) + sizeof(msgpack_zone_chunk);

chunk->next = cl->head;     <------ crashes here
cl->head = chunk;
cl->free = sz - size;
cl->ptr  = ptr + size;

return ptr;

}

My platform is Windows 7 64 bit (using 32 only ... i think), Visual Studio 2010 SP1, Boost 1.48, MsgPack 0.5.4

[qehgt]

I'll check it

[qehgt]

Hmm... myRPC needs a patch to work with latest boost library on win32 platform. Did you make some changes in sources?

Anyway, I checked on Win7 64bit, MSVS Express 2010, Boost 1.48, MsgPack 0.5.4. Everything was compiled in 32-bit mode. Can not reproduce this issue.

[damian123]

Thank you for investigating. I will try to take it in smaller steps and see where I made a mistake.

[qehgt]

Also checked in 64bit mode. Everything was recompiled to 64bit (boost/msgpack/myrpc). Still no issues.

[damian123]

I tried to start from scratch but got stuck with a compiler error, and no header files are in msgpack/type.hpp so can't proceed.
Here is what I did.

1. open command prompt
2. git clone https://github.com/msgpack/msgpack.git
3. open cpp solution and convert in Visual Studio 2010
   a) build but got an error: Cannot open include file: 'sysdep.h'
   added <msgpack_home>\msgpack to additional include directories
   b) build but got an error: Cannot open include file: 'msgpack/unpack_define.h'
   added <msgpack_home> to additional include directories
   c) build but got an error: Cannot open include file: 'zone.hpp'
   can only find the file zone.hpp.erb which configure is supposed to transform into a zone.hpp file.
   can't procees here... go to 4.
4. Download msgpack-0.5.4.tar.gz from http://sourceforge.net/projects/msgpack/files/
5. open msgpack_vc2008.sln and convert it in Visual Studio 2010
6. Build succeeded. Test project not there.
7. Run msgpack_vc.postbuild.bat
8. git clone https://github.com/qehgt/myrpc.git
9. convert project to Visual Studio 2010
10. Replace additional include directories settings to point to my own boost installation
11. Replace additional include directories settings to point msgpack-0.5.4\include
12. Replace additional include directories settings to point myrpc\myrpc
13. Added include path msgpack-0.5.4\src\msgpack
14. Now I have these build errors:

Nice description.

It's a bug in msgpack_vc.postbuild.bat from msgpack-0.5.4.tar.gz.
File type.hpp should be copied into include\msgpack directory, not into include\msgpack\type
So, move type.hpp from include\msgpack\type into include\msgpack to fix build.

[damian123]

Thank you that was helpful for getting ride of the missing type.hpp.

I also have problems since int8_t seems to be defined in both Visual Studio 10's stdint.h and msgpack's sysdep.h.
Any idea how I get ride of this error?

Compiler output
1>------ Build started: Project: myrpc, Configuration: Debug Win32 ------
1> callable.cpp
1>c:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\include\stdint.h(17): error C2371: 'int8_t' : redefinition; different basic types
1> c:\dev\3rdparty\build\msgpack-rpc\msgpack-0.5.4\include\msgpack/sysdep.h(23) : see declaration of 'int8_t'

stdint.h contains this typedef: typedef signed char int8_t;
and sysdep.h contains this typedef: typedef __int8 int8_t;

[qehgt]

Your sysdep.h (from msgpack-0.5.4.tar.gz) is outdated. Take correct one from github repository https://github.com/msgpack/msgpack/raw/master/msgpack/sysdep.h

[damian123]

Cool now I can build myrpc successfuly.
When I run test I get these errors on the console, I believe that my msgpack lib is not in a clean state now.
Will try to take a fresh git clone and merge Windows changes from msgpack-0.5.4. After all cpp version 0.5.4 is from 29 August 2010, quiet old.
Do you have any better ideas?

and on the debug out I have this:

[qehgt]

"internal catch" is just a part of the test. It's expected to see it here.

"First-chance exception" is ok as well. MS debugger prints it every time when a exception is thrown. This test tries to call a function with wrong arguments, this is the reason of the exceptions.

[damian123]

I tried to take the newst version of msgpack from git and added the files that configure will amend from msgpack 0.5.4.
Build myrpc again but still get this error when I run the test project:
i = 1
i = 1
i = 1
internal catch: argument mismatch
i = 1
internal catch: argument mismatch
i = 1
internal catch: argument mismatch
i = 1

Press any key to continue . . .

[damian123]

OK, I will close this ticket. Thank you!

[qehgt]

Ok, I'll change the test to make its output more clear.

[damian123]

Acually it would be nice to have the original cpp unit tests from msgpack-rpc added to myrpc.
I will have a go at that tomorrow.

[qehgt]

That makes sense.

[qehgt]

I updated the test a little. Output now is better.
