bpo-33015: Fix UB in pthread PyThread_start_new_thread (GH-6008)

2018-11-30T15:32:12+00:00

Fix an undefined behaviour in the pthread implementation of
PyThread_start_new_thread(): add a function wrapper to always return
NULL.

Add pythread_callback struct and pythread_wrapper() to thread_pthread.h.

bpo-32593: Drop FreeBSD 9 and older support (#5232)

2018-01-22T17:32:50+00:00

Drop support of FreeBSD 9 and older.

Replace KB unit with KiB (#4293)

2017-11-08T22:44:44+00:00

kB (*kilo* byte) unit means 1000 bytes, whereas KiB ("kibibyte")
means 1024 bytes. KB was misused: replace kB or KB with KiB when
appropriate.

Same change for MB and GB which become MiB and GiB.

Change the output of Tools/iobench/iobench.py.

Round also the size of the documentation from 5.5 MB to 5 MiB.

bpo-30768: Recompute timeout on interrupted lock (GH-4103)

2017-10-24T23:53:32+00:00

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.

bpo-25658: Implement PEP 539 for Thread Specific Storage (TSS) API (GH-1362)

2017-10-06T10:41:34+00:00

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

remove support for BSD/OS (closes bpo-31624) (#3812)

bpo-30860: Consolidate stateful runtime globals. (#3397)

2017-09-08T05:51:28+00:00

* 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).

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

2017-07-03T11:34:38+00:00

* 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
