New submission from Timothy VanSlyke <vanslyk...@husky.neu.edu>: It would be nice for those who write C extensions to have a resource that explicitly states what assumptions are made by the CPython implementation that are otherwise implementation-defined in standard C.
For example, Python versions >= 3.6 require: - That UCHAR_MAX is defined to be 255 (from Python.h) - That fixed-width intXX_t and uintXX_t types are provided in stdint.h and inttypes.h (from PEP7) These two requirements also pretty much guarantee that CHAR_BIT == 8. These kinds of things are nice to know for anybody working with the C API; we can make the same assumptions in our own code without having hunt through the API docs or the CPython source tree every time something comes up. >From what I've found, there isn't any component of the documentation that >explicitly lists these assumptions in one place (I apologize if there is and I >somehow missed it...). Could this be addressed in the future?
