4a21e57fe5 bpo-40268: Remove unused structmember.h includes (GH-19530)
If only offsetof() is needed: include stddef.h instead.

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

e895de3e7f bpo-35813: Tests and docs for shared_memory (#11816)
* Added tests for shared_memory submodule.

* Added tests for ShareableList.

* Fix bug in allocationn size during creation of empty ShareableList illuminated by existing test run on Linux.

* Initial set of docs for shared_memory module.

* Added docs for ShareableList, added doctree entry for shared_memory submodule, name refactoring for greater clarity.

* Added examples to SharedMemoryManager docs, for ease of documentation switched away from exclusively registered functions to some explicit methods on SharedMemoryManager.

* Wording tweaks to docs.

* Fix test failures on Windows.

* Added tests around SharedMemoryManager.

* Documentation tweaks.

* Fix inappropriate test on Windows.

* Further documentation tweaks.

* Fix bare exception.

* Removed __copyright__.

* Fixed typo in doc, removed comment.

* Updated SharedMemoryManager preliminary tests to reflect change of not supporting all registered functions on SyncManager.

* Added Sphinx doctest run controls.

* CloseHandle should be in a finally block in case MapViewOfFile fails.

* Missed opportunity to use with statement.

* Switch to self.addCleanup to spare long try/finally blocks and save one indentation, change to use decorator to skip test instead.

* Simplify the posixshmem extension module.

Provide shm_open() and shm_unlink() functions.  Move other
functionality into the shared_memory.py module.

* Added to doc around size parameter of SharedMemory.

* Changed PosixSharedMemory.size to use os.fstat.

* Change SharedMemory.buf to a read-only property as well as NamedSharedMemory.size.

* Marked as provisional per PEP411 in docstring.

* Changed SharedMemoryTracker to be private.

* Removed registered Proxy Objects from SharedMemoryManager.

* Removed shareable_wrap().

* Removed shareable_wrap() and dangling references to it.

* For consistency added __reduce__ to key classes.

* Fix for potential race condition on Windows for O_CREX.

* Remove unused imports.

* Update access to kernel32 on Windows per feedback from eryksun.

* Moved kernel32 calls to _winapi.

* Removed ShareableList.copy as redundant.

* Changes to _winapi use from eryksun feedback.

* Adopt simpler SharedMemory API, collapsing PosixSharedMemory and WindowsNamedSharedMemory into one.

* Fix missing docstring on class, add test for ignoring size when attaching.

* Moved SharedMemoryManager to managers module, tweak to fragile test.

* Tweak to exception in OpenFileMapping suggested by eryksun.

* Mark a few dangling bits as private as suggested by Giampaolo.

55edd0c185 bpo-33012: Fix invalid function cast warnings with gcc 8 for METH_NOARGS. (GH-6030)
METH_NOARGS functions need only a single argument but they are cast
into a PyCFunction, which takes two arguments.  This triggers an
invalid function cast warning in gcc8 due to the argument mismatch.
Fix this by adding a dummy unused argument.

aefa7ebf0f bpo-6532: Make the thread id an unsigned integer. (#781)
* bpo-6532: Make the thread id an unsigned integer.

From C API side the type of results of PyThread_start_new_thread() and
PyThread_get_thread_ident(), the id parameter of
PyThreadState_SetAsyncExc(), and the thread_id field of PyThreadState
changed from "long" to "unsigned long".

* Restore a check in thread_get_ident().
