bpo-40268: Remove unused structmember.h includes (GH-19530)

PyMemberDef is used.

Lihua Zhao 4fb1502189 bpo-36648: fix mmap issue for VxWorks (GH-12394) 
The mmap module set MAP_SHARED flag when map anonymous memory, however VxWorks
only support MAP_PRIVATE when map anonymous memory, this commit clear MAP_SHARED
and set MAP_PRIVATE.

Zackery Spytz 14514d9084 bpo-36946: Fix possible signed integer overflow when handling slices. (GH-13375) 
The final addition (cur += step) may overflow, so use size_t for "cur".
"cur" is always positive (even for negative steps), so it is safe to use
size_t here.

Berker Peksag e7d4b2f205

Zackery Spytz d6e1404661 bpo-33021: Fix GCC 7 warning (-Wmaybe-uninitialized) in mmapmodule.c (#6117) 2018-03-14 21:08:01 +01:00
Nir Soffer 4484f9dca9 bpo-33021: Release the GIL during fstat() calls (GH-6019) 
fstat may block for long time if the file descriptor is on a
non-responsive NFS server, hanging all threads. Most fstat() calls are
handled by _Py_fstat(), releasing the GIL internally, but but
_Py_fstat_noraise() does not release the GIL, and most calls release the
GIL explicitly around it.

This patch fixes last 2 calls to _Py_fstat_no_raise(), avoiding hangs
when calling:
- mmap.mmap()
- os.urandom()
- random.seed()
