Hi Antoine, In Python 3.4, I added "void PyMem_SetAllocator(PyMemAllocatorDomain domain, PyMemAllocator *allocator)" to the public C API.
Problem: we wanted to add a new "calloc" field to PyMemAllocator structure. I chose to rename the structure to PyMemAllocatorEx to ensure that all C extensions using this function get a compilation error, rather than leaving the new "calloc" field uninitialized. The function became: "void PyMem_SetAllocator(PyMemAllocatorDomain domain, PyMemAllocatorEx *allocator)" I'm not sure what will be the new structure name when we will add new fields (like malloc_aligned) :-( For PyCodeOptions: does it contain posonlyargcount? If not, how do you pass posonlyargcount. I'm not sure if you plan to handle the backward compatibility. Note: In the PEP 587, I added a private "_config_version" field to PyConfig structure to prepare the structure to future extension, but keep backward compatibility. The structure will be versionned ;-) Victor Le jeu. 13 juin 2019 à 01:08, Antoine Pitrou <solip...@pitrou.net> a écrit : > > On Wed, 12 Jun 2019 00:09:10 +0200 > Victor Stinner <vstin...@redhat.com> wrote: > > Update. > > > > Le ven. 31 mai 2019 à 10:49, Petr Viktorin <encu...@gmail.com> a écrit : > > > PEP 570 (Positional-Only Parameters) changed the signatures of > > > PyCode_New() and types.CodeType(), adding a new argument for > > > "posargcount". > > > > Pablo proposed a PR to revert PyCode_New() API to Python 3.7 API: > > https://github.com/python/cpython/pull/13959 > > > > I dislike "PyCode_NewEx" name, it will become worse when another > > parameter will be added in the future.
