* Revert "bpo-33608: Factor out a private, per-interpreter ↵Victor Stinner2019-06-031-18/+10
| | | | | _Py_AddPendingCall(). (gh-13714)" (GH-13780) This reverts commit 6a150bcaeb190d1731b38ab9c7a5d1a352847ddc.

* bpo-36710: Add 'ceval' local variable to ceval.c (GH-12934)Victor Stinner2019-05-101-82/+76
| | | | | | | | | | | | | | | | | | | | | | | | | Add "struct _ceval_runtime_state *ceval = &_PyRuntime.ceval;" local variables to function to better highlight the dependency on the global variable _PyRuntime and to point directly to _PyRuntime.ceval field rather than on the larger _PyRuntime. Changes: * Add _PyRuntimeState_GetThreadState(runtime) macro. * Add _PyEval_AddPendingCall(ceval, ...) and _PyThreadState_Swap(gilstate, ...) functions. * _PyThreadState_GET() macro now calls _PyRuntimeState_GetThreadState() using &_PyRuntime. * Add 'ceval' parameter to COMPUTE_EVAL_BREAKER(), SIGNAL_PENDING_SIGNALS(), _PyEval_SignalAsyncExc(), _PyEval_SignalReceived() and _PyEval_FiniThreads() macros and functions. * Add 'tstate' parameter to call_function(), do_call_core() and do_raise(). * Add 'runtime' parameter to _Py_CURRENTLY_FINALIZING(), _Py_FinishPendingCalls() and _PyThreadState_DeleteExcept() macros and functions. * Declare 'runtime', 'tstate', 'ceval' and 'eval_breaker' variables as constant.

| | | | | _Py_AddPendingCall()." (gh-12806) This reverts commit f13c5c8b9401a9dc19e95d8b420ee100ac022208 (gh-12360).
* bpo-33608: Factor out a private, per-interpreter _Py_AddPendingCall(). ↵Eric Snow2019-04-121-4/+4
| | | | | (gh-12360) This is effectively an un-revert of #11617 and #12024 (reverted in #12159). Portions of those were merged in other PRs (with lower risk) and this represents the remainder. Note that I found 3 different bugs in the original PRs and have fixed them here.

* bpo-33608: Factor out a private, per-interpreter _Py_AddPendingCall(). ↵Eric Snow2019-02-241-4/+4
| | | | | | | (GH-11617) This involves moving the global "pending calls" state to PyInterpreterState. https://bugs.python.org/issue33608
* bpo-35081: Add pycore_ prefix to internal header files (GH-10263)Victor Stinner2018-10-311-1/+1
| | | | | | | | | | | | | | | | | | | | * Rename Include/internal/ header files: * pyatomic.h -> pycore_atomic.h * ceval.h -> pycore_ceval.h * condvar.h -> pycore_condvar.h * context.h -> pycore_context.h * pygetopt.h -> pycore_getopt.h * gil.h -> pycore_gil.h * hamt.h -> pycore_hamt.h * hash.h -> pycore_hash.h * mem.h -> pycore_mem.h * pystate.h -> pycore_state.h * warnings.h -> pycore_warnings.h * PCbuild project, Makefile.pre.in, Modules/Setup: add the Include/internal/ directory to the search paths of header files. * Update includes. For example, replace #include "internal/mem.h" with #include "pycore_mem.h".
* bpo-35081: Move Include/pyatomic.c to Include/internal/ (GH-10239)Victor Stinner2018-10-301-0/+1

* Use Py_uintptr_t for atomic pointersVictor Stinner2016-01-221-4/+4
| | | | | | | | Issue #26161: Use Py_uintptr_t instead of void* for atomic pointers in pyatomic.h. Use atomic_uintptr_t when <stdatomic.h> is used. Using void* causes compilation warnings depending on which implementation of atomic types is used.

* Fix the GIL with subinterpreters. Hopefully this will allow mod_wsgi to work ↵Antoine Pitrou2011-01-151-4/+7
| | | | | | with 3.2. (we need some tests for this)
* Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properlyAntoine Pitrou2010-09-131-0/+21
| | | | | re-created on a subsequent call to Py_Initialize(). The problem (a crash) wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
* Issue #8411: new condition variable emulation under Windows for the new GIL,Antoine Pitrou2010-08-101-52/+105
| | | | | by Kristján. Unfortunately the 3.x Windows buildbots are in a wreck, so we'll have to watch them when they become fit again.
* Make (most of) Python's tests pass under Thread Sanitizer.Jeffrey Yasskin2010-05-031-20/+28
| | | | | | | | | | | | | | | | | | http://code.google.com/p/data-race-test/wiki/ThreadSanitizer is a dynamic data race detector that runs on top of valgrind. With this patch, the binaries at http://code.google.com/p/data-race-test/wiki/ThreadSanitizer#Binaries pass many but not all of the Python tests. All of regrtest still passes outside of tsan. I've implemented part of the C1x atomic types so that we can explicitly mark variables that are used across threads, and get defined behavior as compilers advance. I've added tsan's client header and implementation to the codebase in dynamic_annotations.{h,c} (docs at http://code.google.com/p/data-race-test/wiki/DynamicAnnotations). Unfortunately, I haven't been able to get helgrind and drd to give sensible error messages, even when I use their client annotations, so I'm not supporting them.
* Try to strengthen condition-waiting under Windows.Antoine Pitrou2009-11-121-11/+9
| | | | | If it doesn't work (doesn't solve erratic freezes) we'll have to resort to tougher (Windows-only) measures.
* Our condition variable emulation under Windows is imperfect, whichAntoine Pitrou2009-11-111-9/+24
| | | | | seems to be the cause of the buildbot hangs. Try to fix it, and add some comments.
