bpo-41486: Fix initial buffer size can't > UINT32_MAX in zlib module (GH-25738)

2021-04-30T23:32:49+00:00

* Fix initial buffer size can't > UINT32_MAX in zlib module

After commit f9bedb630e8a0b7d94e1c7e609b20dfaa2b22231, in 64-bit build,
if the initial buffer size > UINT32_MAX, ValueError will be raised.

These two functions are affected:
1. zlib.decompress(data, /, wbits=MAX_WBITS, bufsize=DEF_BUF_SIZE)
2. zlib.Decompress.flush([length])

This commit re-allows the size > UINT32_MAX.

* adds curly braces per PEP 7.

* Renames `Buffer_*` to `OutputBuffer_*` for clarity

bpo-41486: Faster bz2/lzma/zlib via new output buffering (GH-21740)

2021-04-28T06:58:54+00:00

Faster bz2/lzma/zlib via new output buffering.
Also adds .readall() function to _compression.DecompressReader class
to take best advantage of this in the consume-all-output at once scenario.

Often a 5-20% speedup in common scenarios due to less data copying.

If only offsetof() is needed: include stddef.h instead.

When structmember.h is used, add a comment explaining that
PyMemberDef is used.
