* bpo-43908: Make heap types converted during 3.10 alpha immutable (GH-26351) ↵Miss Islington (bot)2021-06-171-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (GH-26766) * Make functools types immutable * Multibyte codec types are now immutable * pyexpat.xmlparser is now immutable * array.arrayiterator is now immutable * _thread types are now immutable * _csv types are now immutable * _queue.SimpleQueue is now immutable * mmap.mmap is now immutable * unicodedata.UCD is now immutable * sqlite3 types are now immutable * _lsprof.Profiler is now immutable * _overlapped.Overlapped is now immutable * _operator types are now immutable * winapi__overlapped.Overlapped is now immutable * _lzma types are now immutable * _bz2 types are now immutable * _dbm.dbm and _gdbm.gdbm are now immutable (cherry picked from commit 00710e6346fd2394aa020b2dfae170093effac98) Co-authored-by: Erlend Egeberg Aasland <erlend.aasland@innova.no> Co-authored-by: Erlend Egeberg Aasland <erlend.aasland@innova.no>
* bpo-41486: Fix initial buffer size can't > UINT32_MAX in zlib module (GH-25738)Ma Lin2021-04-301-16/+17
| | | | | | | | | | | | | | | | * 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)Ma Lin2021-04-281-73/+83
| | | | | | | | | 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. Contributed by Ma Lin.

* bpo-40268: Remove unused structmember.h includes (GH-19530)Victor Stinner2020-04-151-1/+1
| | | | | | If only offsetof() is needed: include stddef.h instead. When structmember.h is used, add a comment explaining that PyMemberDef is used.
* bpo-40268: Remove explicit pythread.h includes (#19529)Victor Stinner2020-04-151-2/+0
| | | | Remove explicit pythread.h includes: it is always included by Python.h.

|\ | | | | | | | | | | | | The underlying C libraries provide no mechanism for serializing compressor and decompressor objects, so actually pickling these classes is impractical. Previously, these objects would be pickled without error, but attempting to use a deserialized instance would segfault the interpreter.
