h3. My CFFI references

Some hints about Setuptools,

We want to use “out-of-line” + “API mode” CFFI with setuptools,
[https://cffi.readthedocs.io/en/release-1.9/cdef.html]
Worked example for a relatively small C API

Python 3 strings

Automatic generation of .pyi typing stub files

Slowest part of cffi seems to be processing the data in interpreted code, in
and out (will be better in PyPy?)

More perf, Cython vs cffi

> Move away from SWIG to CFFI
> ---------------------------
>
> Key: PROTON-2095
> URL: https://issues.apache.org/jira/browse/PROTON-2095
> Project: Qpid Proton
> Issue Type: Wish
> Components: python-binding
> Affects Versions: proton-c-future, proton-c-0.29.0
> Reporter: Omer Katz
> Priority: Major
> Fix For: proton-c-future
>
>
> SWIG is fine but we're not using it for anything other than exporting all of
> proton-c's API as is.
> Unfortunately SWIG only generates CPython extension bindings. This may be a
> problem on PyPy where CPython extensions are either slow or simply won't
> compile.
> Unlike SWIG, CFFI is portable both on CPython and PyPy.
> It also satisfies the same requirements as SWIG currently does.
> In addition, calls to CFFI simply release the GIL which will help
> parallelizing Python applications using threads.
> By using CFFI we can also get rid of all of our setup.py code and simply use
> it to build the extension. We will also no longer have problems building
> wheels.
> The newest version of CFFI supports pkg-config so we can use that to find
> proton-c easily.
> I'm willing to help with the refactor but I'll need a mentor since I'm not
> familiar with the code base.
