* bpo-6532: Make the thread id an unsigned integer. (#781)Serhiy Storchaka2017-03-231-2/+3
| | | | | | | | | | | * 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().

The function now accepts NULL for interp and current_tstate parameters. * test_faulthandler: fix a ResourceWarning when test is interrupted by CTRL+c

It allows to use the function early in Python initialization and late in Python finalization. * Add a flag to disable PyGILState_Check(). Disable PyGILState_Check() when Py_NewInterpreter() is called * Add assert(PyGILState_Check()) to: _Py_dup(), _Py_fstat(), _Py_read() and _Py_write()

| * Add _PyThreadState_UncheckedGet()Victor Stinner2016-01-201-13/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

* PEP 489: Multi-phase extension module initializationNick Coghlan2015-05-231-2/+17
| | | | | | | | | | | | | | | | | | | | | | | Known limitations of the current implementation: - documentation changes are incomplete - there's a reference leak I haven't tracked down yet The leak is most visible by running: ./python -m test -R3:3 test_importlib However, you can also see it by running: ./python -X showrefcount Importing the array or _testmultiphase modules, and then deleting them from both sys.modules and the local namespace shows significant increases in the total number of active references each cycle. By contrast, with _testcapi (which continues to use single-phase initialisation) the global refcounts stabilise after a couple of cycles.

* Issue #19787: PyThread_set_key_value() now always set the valueVictor Stinner2013-12-131-9/+9
| | | | | | | | | | 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.

| | | | | | | | | | | 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.
