      Start using Cython and providing Cython/nogil API · 8fa3c15b
      Kirill Smelkov authored
      Start transforming Pygolang from being pure Python project into project
      that uses both Python and Cython and provides both Python and Cython API
      to its users.
      
      For Cython API there is a goal for it to be usable independently of
      Python GIL - i.e. independently of Python runtime and limitations
      imposed by Python's global interpreter lock. The motivation for this
      work is wendelin.core v2, which, due to its design, would deadlock if it
      tries to take the GIL in its pinner thread.
      
      This commit brings bare minimum establishing libraries and build system.
      It:
      
      - Introduces C/C++ library libgolang. Libgolang will be serving most of
        nogil functionality and Pyx API will be a small wrapper over it. At
        this step Libgolang comes only with C-level panic;
      
      - Introduces Pyx package golang that is aliased to Pyx package
        golang._golang . Users can do `from golang cimport ...` similarly to how
        they do py-level `from golang import ...`. At this step golang.pyx
        only wraps panic and provides way to transform C-level panic into Python
        exception;
      
      - Introduces Py package golang.pyx.build . This package, similarly to
        golang.org/pkg/go/build, serves as the system to build Pyx packages -
        both external packages that use Pygolang in pyx mode, and to build
        Pygolang itself. The build, internally, is served by setuptools_dso
        and cython. An example how to use golang.pyx.build from external
        project comes in golang/pyx/testprog/golang_pyx_user/ and is used by
        tests to verify golang.pyx.build functionality;
      
      - Introduces Pygolang build dependency to cython and setuptools_dso.

      pygopath: Initial draft · 9c61f254
      Kirill Smelkov authored
      Module gopath provides way to import python modules by full path in a Go workspace.
      
      For example
      
          lonet = gopath.gimport('lab.nexedi.com/kirr/go123/xnet/lonet')
      
      will import either
      
          lab.nexedi.com/kirr/go123/xnet/lonet.py, or
          lab.nexedi.com/kirr/go123/xnet/lonet/__init__.py
      
      located somewhere under $GOPATH.
