caolanm / callcatcher Goto Github PK

callanalyse relies on a fixed paths under /tmp : analyse this, analyse that, and doesn't clean up after itself. This breaks concurrent runs (on different projects), or if different users run it - permission denied errors result.

Suggest changing the actual run code to something like:

    tmpdir = tempfile.mkdtemp()
    callcatcher.combine.combine(tmpdir + os.path.sep, inputs)
    callcatcher.analyse.analyse(tmpdir + os.path.sep, "", strict, detailed, LibO, mapfile)
    shutil.rmtree(tmpdir)

and add corresponding imports obviously.

When calling callcatcher on the following cpp file, I'm getting the Broken pipe error:

#include <variant>
#include <string>

std::variant<std::string, int> _variantWithString;

Steps to reproduce:

• save the above as test.cpp
• run callcatcher g++ -c -std=c++17 test.cpp

Result:

callcatcher - detecting compiling:

'g++' '-c' '-std=c++17' 'test.cpp' '-o' '/login/myuser/.callcatcher/login/myuser/test.o' '-O0' '-S'

response file

recently, I've been working on callcatcher for our really large Cpp project, total number of ninjia jobs is up to ~10k.
We use response file to avoid command-line-length issue, callcatcher can expand response file to fix this.

When attempting to use callanalyse, the following errors are produced:

$ callanalyse mybinary
/usr/lib/python2.6/site-packages/callcatcher/lookup.py:42: DeprecationWarning: os.popen2 is deprecated. Use the subprocess module.
self.filtin1, self.filtout1 = os.popen2('c++filt --no-strip-underscore', 'rw')
/usr/lib/python2.6/site-packages/callcatcher/lookup.py:43: DeprecationWarning: os.popen2 is deprecated. Use the subprocess module.
self.filtin2, self.filtout2 = os.popen2('c++filt --strip-underscore', 'rw')

Python version 2.6.6. Probably not relevant, but the binary was compiled with GCC 4.4.7. System info: CentOS 6.4, Linux 3.11.6-x86_64.

The documentation currently states that it should suffice to set:

 export CC="callcatcher gcc"
 export CXX="callcatcher g++"
 export AR="callarchive ar"

While this seems to work for autotools based projects, trying this on a cmake based project just gives the following error:

CMake Error at CMakeLists.txt:2 (project):
  The CMAKE_C_COMPILER:

    callcatcher gcc

  is not a full path to an existing compiler tool.
