* bpo-39946: Remove _PyThreadState_GetFrame (GH-19094)Victor Stinner2020-03-201-0/+3
| | | | | 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 Stinner2020-03-201-0/+2
| | | | Add PyThreadState_GetFrame() function: get the current frame of a Python thread state.
* bpo-40010: Optimize pending calls in multithreaded applications (GH-19091)Victor Stinner2020-03-201-0/+8
| | | | | | | | | | | | | | | If a thread different than the main thread schedules a pending call (Py_AddPendingCall()), the bytecode evaluation loop is no longer interrupted at each bytecode instruction to check for pending calls which cannot be executed. Only the main thread can execute pending calls. Previously, the bytecode evaluation loop was interrupted at each instruction until the main thread executes pending calls. * Add _Py_ThreadCanHandlePendingCalls() function. * SIGNAL_PENDING_CALLS() now only sets eval_breaker to 1 if the current thread can execute pending calls. Only the main thread can execute pending calls.

* bpo-40019: Skip test_gdb if Python was optimized (GH-19081)Victor Stinner2020-03-201-0/+2
| | | | test_gdb now skips tests if it detects that gdb failed to read debug information because the Python binary is optimized.
* bpo-40010: Optimize signal handling in multithreaded applications (GH-19067)Victor Stinner2020-03-191-0/+8
| | | | | | | | | | | | | | | 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 Stinner2020-03-191-0/+4
| | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | subinterpreters: Move _PyRuntimeState.ceval.tracing_possible to PyInterpreterState.ceval.tracing_possible: each interpreter now has its own variable. Changes: * Add _ceval_state structure. * Add PyInterpreterState.ceval field. * _PyEval_EvalFrameDefault(): add ceval2 variable (struct _ceval_state*). * Rename _PyEval_Initialize() to _PyEval_InitRuntimeState(). * Add _PyEval_InitState(). * Don't export internal _Py_FinishPendingCalls() and _PyEval_FiniThreads() functions anymore.

* bpo-39824: module_traverse() don't call m_traverse if md_state=NULL (GH-18738)Victor Stinner2020-03-171-0/+10
| | | | | | | | | | | | | 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>

* bpo-39360: Ensure all workers exit when finalizing a multiprocessing Pool ↵Batuhan Taşkaya2020-03-151-0/+4
| | | | | | | | | (GH-19009) When the pull is not used via the context manager or terminate() is called, there is a system in multiprocessing.util that handles finalization of all pools via an atexit handler (the Finalize) class. This class registers the _terminate_pool handler in the registry of finalizers of the module, and that registry is called on interpreter exit via _exit_function. The problem is that the "happy" path with the context manager or manual call to finalize() does some extra steps that _terminate_pool does not. The step that is not executed when the atexit() handler calls _terminate_pool is pinging the _change_notifier queue to unblock the maintenance threads. This commit moves the notification to the _terminate_pool function so is called from both code paths. Co-authored-by: Pablo Galindo <Pablogsal@gmail.com>
