| | | | | | Remove daemon threads from :mod:`concurrent.futures` by adding an internal `threading._register_atexit()`, which calls registered functions prior to joining all non-daemon threads. This allows for compatibility with subinterpreters, which don't support daemon threads.

* bpo-39946: Remove _PyThreadState_GetFrame (GH-19094)Victor Stinner2020-03-201-0/+4
| | | | | Remove _PyRuntime.getframe hook and remove _PyThreadState_GetFrame macro which was an alias to _PyRuntime.getframe. They were only exposed by the internal C API. Remove also PyThreadFrameGetter type.
* bpo-39947: Add PyThreadState_GetFrame() function (GH-19092)Victor Stinner2020-03-203-4/+21
| | | | Add PyThreadState_GetFrame() function: get the current frame of a Python thread state.
* bpo-40010: COMPUTE_EVAL_BREAKER() checks for subinterpreter (GH-19087)Victor Stinner2020-03-201-5/+7
| | | | | | | | | COMPUTE_EVAL_BREAKER() now also checks if the Python thread state belongs to the main interpreter. Don't break the evaluation loop if there are pending signals but the Python thread state it belongs to a subinterpeter. * Add _Py_IsMainThread() function. * Add _Py_ThreadCanHandleSignals() function.

* Fix "versionchanged" for pow named arguments (GH-19042)Mark Dickinson2020-03-191-1/+1
| | | The ability to use named arguments in "pow" was introduced in Python 3.8, not Python 3.9. See https://bugs.python.org/issue38237
* bpo-40010: Optimize signal handling in multithreaded applications (GH-19067)Victor Stinner2020-03-191-0/+10
| | | | | | | | | | | | | | | If a thread different than the main thread gets a signal, the bytecode evaluation loop is no longer interrupted at each bytecode instruction to check for pending signals which cannot be handled. Only the main thread of the main interpreter can handle signals. Previously, the bytecode evaluation loop was interrupted at each instruction until the main thread handles signals. Changes: * COMPUTE_EVAL_BREAKER() and SIGNAL_PENDING_SIGNALS() no longer set eval_breaker to 1 if the current thread cannot handle signals. * take_gil() now always recomputes eval_breaker.
* bpo-39984: Move pending calls to PyInterpreterState (GH-19066)Victor Stinner2020-03-192-0/+16
| | | | | | | | | | | | | | | | | If Py_AddPendingCall() is called in a subinterpreter, the function is now scheduled to be called from the subinterpreter, rather than being called from the main interpreter. Each subinterpreter now has its own list of scheduled calls. * Move pending and eval_breaker fields from _PyRuntimeState.ceval to PyInterpreterState.ceval. * new_interpreter() now calls _PyEval_InitThreads() to create pending calls lock. * Fix Py_AddPendingCall() for subinterpreters. It now calls _PyThreadState_GET() which works in a subinterpreter if the caller holds the GIL, and only falls back on PyGILState_GetThisThreadState() if _PyThreadState_GET() returns NULL.

* bpo-39824: module_traverse() don't call m_traverse if md_state=NULL (GH-18738)Victor Stinner2020-03-172-10/+45
| | | | | | | | | | | | | Extension modules: m_traverse, m_clear and m_free functions of PyModuleDef are no longer called if the module state was requested but is not allocated yet. This is the case immediately after the module is created and before the module is executed (Py_mod_exec function). More precisely, these functions are not called if m_size is greater than 0 and the module state (as returned by PyModule_GetState()) is NULL. Extension modules without module state (m_size <= 0) are not affected. Co-Authored-By: Petr Viktorin <encukou@gmail.com>
