* bpo-30860: Fix a refleak. (#3567)Eric Snow2017-09-141-2/+0
| | | | | Resolves bpo-31420. (This was accidentally reverted when in #3565.)
* bpo-31404: Revert "remove modules from Py_InterpreterState (#1638)" (#3565)Eric Snow2017-09-141-0/+3
| | | PR #1638, for bpo-28411, causes problems in some (very) edge cases. Until that gets sorted out, we're reverting the merge. PR #3506, a fix on top of #1638, is also getting reverted.
* bpo-30860: Fix a refleak. (#3506)Eric Snow2017-09-121-2/+0
| | | | | | | | | | | | | | * Drop warnoptions from PyInterpreterState. * Drop xoptions from PyInterpreterState. * Don't set warnoptions and _xoptions again. * Decref after adding to sys.__dict__. * Drop an unused macro. * Check sys.xoptions *before* we delete it.
* bpo-30860: Consolidate stateful runtime globals. (#3397)Eric Snow2017-09-081-14/+16
| | | | | | | * 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-31344: Per-frame control of trace events (GH-3417)Nick Coghlan2017-09-081-1/+6
| | | | | | | | | f_trace_lines: enable/disable line trace events f_trace_opcodes: enable/disable opcode trace events These are intended primarily for testing of the interpreter itself, as they make it much easier to emulate signals arriving at unfortunate times.
* bpo-31370: Remove support for threads-less builds (#3385)Antoine Pitrou2017-09-071-4/+0
| | | | | | * Remove Setup.config * Always define WITH_THREAD for compatibility.
* Revert "bpo-30860: Consolidate stateful runtime globals." (#3379)Eric Snow2017-09-061-16/+14
| | | Windows buildbots started failing due to include-related errors.

* bpo-22257: Private C-API for core runtime initialization (PEP 432). (#1772)Eric Snow2017-05-241-0/+11
| | | (patch by Nick Coghlan)
* bpo-22257: Small changes for PEP 432. (#1728)Eric Snow2017-05-231-0/+1
| | | PEP 432 specifies a number of large changes to interpreter startup code, including exposing a cleaner C-API. The major changes depend on a number of smaller changes. This patch includes all those smaller changes.
* bpo-29102: Add a unique ID to PyInterpreterState. (#1639)Eric Snow2017-05-231-0/+9

* bpo-6532: Make the thread id an unsigned integer. (#781)Serhiy Storchaka2017-03-231-2/+2
| | | | | | | | | | | * 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().

It allows to use the function early in Python initialization and late in Python finalization. * Add a flag to disable PyGILState_Check().

* Add _PyThreadState_UncheckedGet()Victor Stinner2016-01-201-0/+10
| | | | | | | | | | | | | | | | | | | Issue #26154: Add a new private _PyThreadState_UncheckedGet() function which gets the current thread state, but don't call Py_FatalError() if it is NULL. Python 3.5.1 removed the _PyThreadState_Current symbol from the Python C API to no more expose complex and private atomic types. Atomic types depends on the compiler or can even depend on compiler options. The new function _PyThreadState_UncheckedGet() allows to get the variable value without having to care of the exact implementation of atomic types. Changes: * Replace direct usage of the _PyThreadState_Current variable with a call to _PyThreadState_UncheckedGet(). * In pystate.c, replace direct usage of the _PyThreadState_Current variable with the PyThreadState_GET() macro for readability. * Document also PyThreadState_Get() in pystate.h
* Issue #25150: Hide the private _Py_atomic_xxx symbols from the publicVictor Stinner2015-09-181-12/+5
| | | | | | | | | Python.h header to fix a compilation error with OpenMP. PyThreadState_GET() becomes an alias to PyThreadState_Get() to avoid ABI incompatibilies. It is important that the _PyThreadState_Current variable is always accessed with the same implementation of pyatomic.h. Use the PyThreadState_Get() function so extension modules will all reuse the same implementation.

| | | | | | | | Disable completly pyatomic.h on C++, because <stdatomic.h> is not compatible with C++. <pyatomic.h> is only needed by the optimized PyThreadState_GET() macro in pystate.h. Instead, declare PyThreadState_GET() as an alias to PyThreadState_Get(), as done for limited API.

| | | | | | | | | | | sporadic crashes in multi-thread programs when several long deallocator chains ran concurrently and involved subclasses of built-in container types. Because of this change, a couple extension modules compiled for 3.2.4 (those which use the trashcan mechanism, despite it being undocumented) will not be loadable by 3.2.3 and earlier. However, extension modules compiled for 3.2.3 and earlier will be loadable by 3.2.4.
