* bpo-44434: Don't call PyThread_exit_thread() explicitly (GH-26758) (GH-26824)Miss Islington (bot)2021-06-211-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | _thread.start_new_thread() no longer calls PyThread_exit_thread() explicitly at the thread exit, the call was redundant. On Linux with the glibc, pthread_cancel() loads dynamically the libgcc_s.so.1 library. dlopen() can fail if there is no more available file descriptor to open the file. In this case, the process aborts with the error message: "libgcc_s.so.1 must be installed for pthread_cancel to work" pthread_cancel() unwinds back to the thread's wrapping function that calls the thread entry point. The unwind function is dynamically loaded from the libgcc_s library since it is tightly coupled to the C compiler (GCC). The unwinder depends on DWARF, the compiler generates DWARF, so the unwinder belongs to the compiler. Thanks Florian Weimer and Carlos O'Donell for their help on investigating this issue.

* bpo-42972: _thread.RLock implements the GH protocol (GH-26734)Miss Islington (bot)2021-06-151-1/+10
| | | | | | | The _thread.RLock type now fully implement the GC protocol: add a traverse function and the Py_TPFLAGS_HAVE_GC flag. (cherry picked from commit 1cd3d859a49b047dd08abb6f44f0539564d3525a) Co-authored-by: Victor Stinner <vstinner@python.org>
* bpo-43916: Apply Py_TPFLAGS_DISALLOW_INSTANTIATION to selected types (GH-25748)Erlend Egeberg Aasland2021-04-301-2/+3
| | | | | | | | | | | | | | | | | | | | | Apply Py_TPFLAGS_DISALLOW_INSTANTIATION to the following types: * _dbm.dbm * _gdbm.gdbm * _multibytecodec.MultibyteCodec * _sre..SRE_Scanner * _thread._localdummy * _thread.lock * _winapi.Overlapped * array.arrayiterator * functools.KeyWrapper * functools._lru_list_elem * pyexpat.xmlparser * re.Match * re.Pattern * unicodedata.UCD * zlib.Compress * zlib.Decompress
* bpo-40137: Add pycore_moduleobject.h internal header (GH-25507)Victor Stinner2021-04-211-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add pycore_moduleobject.h internal header file with static inline functions to access module members: * _PyModule_GetDict() * _PyModule_GetDef() * _PyModule_GetState() These functions don't check at runtime if their argument has a valid type and can be inlined even if Python is not built with LTO. _PyType_GetModuleByDef() uses _PyModule_GetDef(). Replace PyModule_GetState() with _PyModule_GetState() in the extension modules, considered as performance sensitive: * _abc * _functools * _operator * _pickle * _queue * _random * _sre * _struct * _thread * _winapi * array * posix The following extensions are now built with the Py_BUILD_CORE_MODULE macro defined, to be able to use the internal pycore_moduleobject.h header: _abc, array, _operator, _queue, _sre, _struct.
* bpo-43356: Allow passing a signal number to interrupt_main() (GH-24755)Antoine Pitrou2021-03-111-7/+23
| | | | Also introduce a new C API ``PyErr_SetInterruptEx(int signum)``.
* bpo-43268: local_clear() uses _PyInterpreterState_GET() (GH-24583)Victor Stinner2021-02-191-15/+14

* bpo-1635741: Port _thread to multiphase init (GH-23811)Victor Stinner2020-12-181-90/+221
| | | | | | | Port the _thread extension module to the multiphase initialization API (PEP 489) and convert its static types to heap types. Add a traverse function to the lock type, so the garbage collector can break reference cycles.
* bpo-1635741: Refactor _threadmodule.c (GH-23793)Victor Stinner2020-12-161-311/+226
| | | | | | | | | | | | | * Fix ExceptHookArgsType name: "_thread.ExceptHookArgs", instead of "_thread._ExceptHookArgs". * PyInit__thread() no longer intializes interp->num_threads to 0: it is already done in PyInterpreterState_New(). * Use PyModule_AddType(), Py_NewRef() and Py_XNewRef(). * Replace str_dict variable with _Py_IDENTIFIER(__dict__). * Remove assert(Py_IS_TYPE(obj, &Locktype)) from release_sentinel() to avoid having to retrive the type from this callback. * Add thread_bootstate_free() * Rename t_bootstrap() to thread_run() * bootstate structure: rename keyw member to kwargs
* bpo-42519: Replace PyObject_MALLOC() with PyObject_Malloc() (GH-23587)Victor Stinner2020-12-011-1/+1
| | | | | | | | | No longer use deprecated aliases to functions: * Replace PyObject_MALLOC() with PyObject_Malloc() * Replace PyObject_REALLOC() with PyObject_Realloc() * Replace PyObject_FREE() with PyObject_Free() * Replace PyObject_Del() with PyObject_Free() * Replace PyObject_DEL() with PyObject_Free()
* bpo-42519: Replace PyMem_MALLOC() with PyMem_Malloc() (GH-23586)Victor Stinner2020-12-011-3/+3
| | | | | | | | | | | No longer use deprecated aliases to functions: * Replace PyMem_MALLOC() with PyMem_Malloc() * Replace PyMem_REALLOC() with PyMem_Realloc() * Replace PyMem_FREE() with PyMem_Free() * Replace PyMem_Del() with PyMem_Free() * Replace PyMem_DEL() with PyMem_Free() Modify also the PyMem_DEL() macro to use directly PyMem_Free().
* bpo-42006: Stop using PyDict_GetItem, PyDict_GetItemString and ↵Serhiy Storchaka2020-10-261-2/+6
| | | | | | | | | | | _PyDict_GetItemId. (GH-22648) These functions are considered not safe because they suppress all internal errors and can return wrong result. PyDict_GetItemString and _PyDict_GetItemId can also silence current exception in rare cases. Remove no longer used _PyDict_GetItemId. Add _PyDict_ContainsId and rename _PyDict_Contains into _PyDict_Contains_KnownHash.
* bpo-40453: Add PyConfig._isolated_subinterpreter (GH-19820)Victor Stinner2020-05-011-0/+8
| | | | | | | | | An isolated subinterpreter cannot spawn threads, spawn a child process or call os.fork(). * Add private _Py_NewInterpreter(isolated_subinterpreter) function. * Add isolated=True keyword-only parameter to _xxsubinterpreters.create(). * Allow again os.fork() in "non-isolated" subinterpreters.
* bpo-40268: Remove unused structmember.h includes (GH-19530)Victor Stinner2020-04-151-5/+3
| | | | | | If only offsetof() is needed: include stddef.h instead. When structmember.h is used, add a comment explaining that PyMemberDef is used.
* bpo-40268: Remove explicit pythread.h includes (#19529)Victor Stinner2020-04-151-1/+0
| | | | Remove explicit pythread.h includes: it is always included by Python.h.
* bpo-40268: Remove a few pycore_pystate.h includes (GH-19510)Victor Stinner2020-04-141-1/+1
|
* bpo-40268: Rename _PyInterpreterState_GET_UNSAFE() (GH-19509)Victor Stinner2020-04-141-3/+3
| | | | | | | Rename _PyInterpreterState_GET_UNSAFE() to _PyInterpreterState_GET() for consistency with _PyThreadState_GET() and to have a shorter name (help to fit into 80 columns). Add also "assert(tstate != NULL);" to the function.
* bpo-40268: Include explicitly pycore_interp.h (GH-19505)Victor Stinner2020-04-141-1/+2
| | | | pycore_pystate.h no longer includes pycore_interp.h: it's now included explicitly in files accessing PyInterpreterState.
* bpo-40234: Revert "bpo-37266: Daemon threads are now denied in ↵Victor Stinner2020-04-121-24/+0
| | | | | subinterpreters (GH-14049)" (GH-19456) This reverts commit 066e5b1a917ec2134e8997d2cadd815724314252.
* bpo-40089: Add _at_fork_reinit() method to locks (GH-19195)Victor Stinner2020-04-071-14/+53
| | | | | | | | | | | | | | | Add a private _at_fork_reinit() method to _thread.Lock, _thread.RLock, threading.RLock and threading.Condition classes: reinitialize the lock after fork in the child process; reset the lock to the unlocked state. Rename also the private _reset_internal_locks() method of threading.Event to _at_fork_reinit(). * Add _PyThread_at_fork_reinit() private function. It is excluded from the limited C API. * threading.Thread._reset_internal_locks() now calls _at_fork_reinit() on self._tstate_lock rather than creating a new Python lock object.
* Remove unused variable to fix compiler warning in _threadmodule.c (GH-19064)Pablo Galindo2020-03-181-2/+0

* bpo-39984: _PyThreadState_DeleteCurrent() takes tstate (GH-19051)Victor Stinner2020-03-181-1/+1
| | | | | | | | | | * _PyThreadState_DeleteCurrent() now takes tstate rather than runtime. * Add ensure_tstate_not_null() helper to pystate.c. * Add _PyEval_ReleaseLock() function. * _PyThreadState_DeleteCurrent() now calls _PyEval_ReleaseLock(tstate) and frees PyThreadState memory after this call, not before. * PyGILState_Release(): rename "tcur" variable to "tstate".
* bpo-39947: Use _PyInterpreterState_GET_UNSAFE() (GH-18978)Victor Stinner2020-03-131-3/+3
| | | | | | | Replace _PyInterpreterState_Get() function call with _PyInterpreterState_GET_UNSAFE() macro which is more efficient but don't check if tstate or interp is NULL. _Py_GetConfigsAsDict() now uses _PyThreadState_GET().
* bpo-39877: Remove useless PyEval_InitThreads() calls (GH-18883)Victor Stinner2020-03-091-1/+1
| | | | Py_Initialize() calls PyEval_InitThreads() since Python 3.7. It's no longer needed to call it explicitly.
* bpo-39573: Use Py_IS_TYPE() macro to check for types (GH-18809)Andy Lester2020-03-061-2/+2

|
* bpo-36710: Add PyInterpreterState.runtime field (GH-17270)Victor Stinner2019-11-201-1/+1
| | | | | | | | | | | Add PyInterpreterState.runtime field: reference to the _PyRuntime global variable. This field exists to not have to pass runtime in addition to tstate to a function. Get runtime from tstate: tstate->interp->runtime. Remove "_PyRuntimeState *runtime" parameter from functions already taking a "PyThreadState *tstate" parameter. _PyGC_Init() first parameter becomes "PyThreadState *tstate".
* bpo-37878: Remove PyThreadState_DeleteCurrent() function (GH-15315)Joannah Nanjekye2019-09-051-2/+7

* bpo-37266: Daemon threads are now denied in subinterpreters (GH-14049)Victor Stinner2019-06-141-0/+24
| | | | | | | | | | | | In a subinterpreter, spawning a daemon thread now raises an exception. Daemon threads were never supported in subinterpreters. Previously, the subinterpreter finalization crashed with a Pyton fatal error if a daemon thread was still running. * Add _thread._is_main_interpreter() * threading.Thread.start() now raises RuntimeError if the thread is a daemon thread and the method is called from a subinterpreter. * The _thread module now uses Argument Clinic for the new function. * Use textwrap.dedent() in test_threading.SubinterpThreadingTests

* bpo-37076: _thread.start_new_thread() calls _PyErr_WriteUnraisableMsg() ↵Victor Stinner2019-05-291-14/+4
| | | | | | | (GH-13617) _thread.start_new_thread() now logs uncaught exception raised by the function using sys.unraisablehook(), rather than sys.excepthook(), so the hook gets access to the function which raised the exception.
* bpo-1230540: Add threading.excepthook() (GH-13515)Victor Stinner2019-05-271-0/+156
| | | | | | | | | | | | | | | | | | | Add a new threading.excepthook() function which handles uncaught Thread.run() exception. It can be overridden to control how uncaught exceptions are handled. threading.ExceptHookArgs is not documented on purpose: it should not be used directly. * threading.excepthook() and threading.ExceptHookArgs. * Add _PyErr_Display(): similar to PyErr_Display(), but accept a 'file' parameter. * Add _thread._excepthook(): C implementation of the exception hook calling _PyErr_Display(). * Add _thread._ExceptHookArgs: structseq type. * Add threading._invoke_excepthook_wrapper() which handles the gory details to ensure that everything remains alive during Python shutdown. * Add unit tests.
