850a18e03e bpo-30768: Recompute timeout on interrupted lock (GH-4103)
Fix the pthread+semaphore implementation of
PyThread_acquire_lock_timed() when called with timeout > 0 and
intr_flag=0: recompute the timeout if sem_timedwait() is interrupted
by a signal (EINTR).

See also the PEP 475.

The pthread implementation of PyThread_acquire_lock() now fails with
a fatal error if the timeout is larger than PY_TIMEOUT_MAX, as done
in the Windows implementation.

The check prevents any risk of overflow in PyThread_acquire_lock().

Add also PY_DWORD_MAX constant.

731e189014 bpo-25658: Implement PEP 539 for Thread Specific Storage (TSS) API (GH-1362)
See PEP 539 for details.

Highlights of changes:

- Add Thread Specific Storage (TSS) API
- Document the Thread Local Storage (TLS) API as deprecated
- Update code that used TLS API to use TSS API

2ebc5ce42a bpo-30860: Consolidate stateful runtime globals. (#3397)
* group the (stateful) runtime globals into various topical structs
* consolidate the topical structs under a single top-level _PyRuntimeState struct
* add a check-c-globals.py script that helps identify runtime globals

Other globals are excluded (see globals.txt and check-c-globals.py).

aa0aa0492c bpo-30832: Remove own implementation for thread-local storage (#2537)
* bpo-30832: Remove own implementation for thread-local storage

CPython has provided the own implementation for thread-local storage
(TLS) on Python/thread.c, it's used in the case which a platform has
not supplied native TLS.  However, currently all supported platforms
(NT and pthreads) have provided native TLS and defined the
Py_HAVE_NATIVE_TLS macro with unconditional in any case.

* bpo-30832: replace NT with Windows

* bpo-30832: change to directive chain

* bpo-30832: remove comemnt which making no sense

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().

33096fe829 The PyCOND_TIMEDWAIT must use microseconds for the timeout argument
in order to have the same resolution as pthreads condition variables.
At the same time, it must be large enough to accept 31 bits of
milliseconds, which is the maximum timeout value in the windows API.
A PY_LONG_LONG of microseconds fullfills both requirements.
This closes issue #20737

590cebe391 Issue #19787: PyThread_set_key_value() now always set the value
In Python 3.3, PyThread_set_key_value() did nothing if the key already exists
(if the current value is a non-NULL pointer).

When _PyGILState_NoteThreadState() is called twice on the same thread with a
different Python thread state, it still keeps the old Python thread state to
keep the old behaviour. Replacing the Python thread state with the new state
introduces new bugs: see issues #10915 and #15751.

    Fix problems in x64 build that were discovered by the testsuite:
    - Reenable modules on x64 that had been disabled aeons ago for Itanium.
    - Cleared up confusion about compilers for 64 bit windows.  There is only Itanium and x64.  Added macros MS_WINI64 and MS_WINX64 for those rare cases where it matters, such as the disabling of modules above.
    - Set target platform (_WIN32_WINNT and WINVER) to 0x0501 (XP) for x64, and 0x0400 (NT 4.0) otherwise, which are the targeted minimum platforms.
    - Fixed thread_nt.h.  The emulated InterlockedCompareExchange function didn?\194?\180t work on x64, probaby due to the lack of a "volatile" specifier.  Anyway, win95 is no longer a target platform.
    - Itertools module used wrong constant to check for overflow in count()
    - PyInt_AsSsize_t couldn't deal with attribute error when accessing the __long__ member.
    - PyLong_FromSsize_t() incorrectly specified that the operand were unsigned.

    With these changes, the x64 passes the testsuite, for those modules present.

    Fix a bug in test.test_support.open_urlresource().

    If the call to requires() doesn't precede the filesystem check, we get the following situation:
    1. ./python Lib/test/regrtest.py test_foo # test needs urlfetch, not enabled, so skipped
    2. ./python Lib/test/regrtest.py -u urlfetch test_foo # test runs
    3. ./python Lib/test/regrtest.py test_foo # test runs (!)

    By moving the call to requires() *before* the filesystem check, the fact that fetched files are cached on the local disk becomes an implementation detail, rather than a semantics-changing point of note.
