Vmprof Python Versions Save

• register_virtual_function cannot exhaust the buffers any more
• do not write over the boundary of the buffer that contains the stack trace
• print better warnings when the program run is too short
• add vmprof.is_enabled/vmprof.get_profile_path
• Pull request (only needed symbols), do not log function names that are not in the profile
• Better descriptor checks (e.g. cannot give a non writable fd to vmprof.enable)
• Warn user if vmprof file is bigger than 100 MB and uploaded to vmprof.com (might be rejected)
• Source distribution includes dwarf.def and other files required to build
• osx: dlopen+dlsym not used for libunwind (use standard way to link to libunwind)

• pypy support to native profiling
• dumping native symbols is not implemented in C (to not maintain a C and a Python version)
• sample_stack_now has an optional paramter 'skip' which skips a certain amount of native frames
• win64 + cpython 3.6 compilation issue solved
• dynamic loading of libunwind symbols (to support pypy)
• added sqlite sample file
• do not overwrite base_headers for http requests if authorization is provided

Serveral enhancements

• #116 vmprof hangs when multiple threads frequently release/acquire the GIl
• #118 vmprofshow breaks on multiline dictionary comprehensions
• PyPy jit log issues

• Native profiling (C stack) is included in the profile (using libunwind) for Linux & Mac
• Windows 64bit support (no native profiling)
• The platform that reads the profile can be different from the platform that generated it
• vmprof.com updates to the flamegraph and general style changes
• Documentation updates

• Invoking ... -m vmprof --jitlog ... did not upload source snippets to the remote server

• Signals arriving while spent in native code (GIL released) often did not sample the correct stack (Linux, Mac)

• GZip compression of vmprof files
• Improved Exception handling and displaying on vmprof-server
