Found a backward incompatible behavior. Before the patch, in 64-bit build, zlib module allows the initial size > UINT32_MAX. It creates a bytes object, and uses a sliding window to deal with the UINT32_MAX limit: https://github.com/python/cpython/blob/v3.9.4/Modules/zlibmodule.c#L183 After the patch, when init_size > UINT32_MAX, it raises a ValueError. PR 25738 fixes this backward incompatibility. If the initial size > UINT32_MAX, it clamps to UINT32_MAX, rather than raising an exception. Moreover, if you don't mind, I would like to take this opportunity to rename the wrapper functions from Buffer_* to OutputBuffer_*, so that the readers can easily distinguish between input buffer and output buffer. If you don't think it's necessary, you may merge PR 25738 as is. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue41486> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
