Hi,
Our bundled copy of libffi has been removed from Python 3.7 by this change which should explain the rationale: https://bugs.python.org/issue27979
Thanks.
Not all Python changes need a PEP. For Windows builds, we provide prebuilt binaries of our dependencies: https://github.com/python/cpython-source-deps/blob/master/README.rst
I am OK with Windows, it is Linux, as below.
My notes on Python dependencies: https://pythondev.readthedocs.io/files.html
Again, thanks for this.
we support older Linux distributions that don't have libffi
I'm curious, which old Linux distributions don't have libffi? Usually, libffi is preinstalled on Linux, only the development header files are required (a package with a name like "libffi-devel"). Can't you install libffi on these old distributions? IMHO libffi installation should not be the Python problem, bundling a library copy in Python is causing more issues compared to advantages.
RHEL/CentOS 5 come to mind. We don't want to get into the use case where we have to have customers install libffi as we try to minimize the hassles our customers might have to go through for installing and using our product. Tom
