I've recently been adding better support to Numpy 1.16 for interoperability with ctypes.
In doing so, I came across two bugs in the implementation of the
PEP3118 buffer interface within ctypes, affecting Structures and
arrays. Rather than repeating the issue summaries here, I've linked
their tracker issues below, and the patches I filed to fix them.
- https://bugs.python.org/issue32782 (patch: https://github.com/python/cpython/pull/5576)
- https://bugs.python.org/issue32780 (patch: https://github.com/python/cpython/pull/5561)
I've seen little to no response on either the bug tracker or the github PRs regarding these, so at the recommendation of the "Lifecycle of a Pull Request" am emailing this list.
Without these fixes, numpy has no choice but to ignore the broken buffer interface that ctypes provides, and instead try to parse the ctypes types manually. The sooner this makes a CPython release, the sooner numpy can remove those workarounds.
Thanks, Eric
