* gh-98930: improve the docstring of signal.strsignal (#99290)ram vikram singh2022-11-131-3/+4
| | | | | | | Improves the docstring on signal.strsignal to make it explain when it returns a message, None, or when it raises ValueError. Closes #98930 Co-authored-by: Gregory P. Smith <greg@krypto.org>
* signalmodule.c uses _PyErr_WriteUnraisableMsg() (#98217)Victor Stinner2022-10-121-7/+6
| | | | | | | Signal wakeup fd errors are now logged with _PyErr_WriteUnraisableMsg(), rather than PySys_WriteStderr() and PyErr_WriteUnraisable(), to pass the error message to sys.unraisablehook. By default, it's still written into stderr (unless sys.unraisablehook is overriden).

* gh-91320: Use _PyCFunction_CAST() (#92251)Victor Stinner2022-05-031-1/+1
| | | | | | | | | | Replace "(PyCFunction)(void(*)(void))func" cast with _PyCFunction_CAST(func). Change generated by the command: sed -i -e \ 's!(PyCFunction)(void(\*)(void)) *\([A-Za-z0-9_]\+\)!_PyCFunction_CAST(\1)!g' \ $(find -name "*.c")
* gh-64783: Fix signal.NSIG value on FreeBSD (#91929)Victor Stinner2022-04-251-16/+18
| | | | | | | | | Fix signal.NSIG value on FreeBSD to accept signal numbers greater than 32, like signal.SIGRTMIN and signal.SIGRTMAX. * Add Py_NSIG constant. * Add pycore_signal.h internal header file. * _Py_Sigset_Converter() now includes the range of valid signals in the error message.
* gh-90623: signal.raise_signal() calls PyErr_CheckSignals() (#91756)Victor Stinner2022-04-211-0/+7
| | | | signal.raise_signal() and os.kill() now call PyErr_CheckSignals() to check immediately for pending signals.
* bpo-47176: Interrupt handling for wasm32-emscripten builds without pthreads ↵Hood Chatham2022-04-031-0/+2

* bpo-46836: Rename InterpreterFrame to _PyInterpreterFrame (GH-31583)Victor Stinner2022-02-251-2/+2
| | | | | Rename also struct _interpreter_frame to struct _PyInterpreterFrame. Reduce risk of name conflicts if a project includes pycore_frame.h.
* bpo-46417: signal: move siginfo_type to the module state (GH-30964)Victor Stinner2022-01-271-19/+20
|
* bpo-46417: signal uses PyStructSequence_NewType() (GH-30735)Victor Stinner2022-01-211-7/+9
| | | | | | The signal module now creates its struct_siginfo type as a heap type using PyStructSequence_NewType(), rather than using a static type. Add 'siginfo_type' member to the global signal_state_t structure.
* bpo-45953: Statically allocate the main interpreter (and initial thread ↵Eric Snow2022-01-121-1/+1
| | | | | | | | | state). (gh-29883) Previously, the main interpreter was allocated on the heap during runtime initialization. Here we instead embed it into _PyRuntimeState, which means it is statically allocated as part of the _PyRuntime global. The same goes for the initial thread state (of each interpreter, including the main one). Consequently there are fewer allocations during runtime/interpreter init, fewer possible failures, and better memory locality. FYI, this also helps efforts to consolidate globals, which in turns helps work on subinterpreter isolation. https://bugs.python.org/issue45953
* bpo-45643: Add signal.SIGSTKFLT on platforms where this is defined (GH-29266)Gareth Rees2021-12-131-0/+3

* bpo-41498: Fix build on platforms without sigset_t (GH-29770)Christian Heimes2021-11-251-3/+10
|
* bpo-45637: Store the frame pointer in the cframe (GH-29267)Mark Shannon2021-10-281-1/+1
| | | * Rename 'frame' to 'current_frame'
* bpo-45434: Move _Py_BEGIN_SUPPRESS_IPH to pycore_fileutils.h (GH-28922)Victor Stinner2021-10-131-0/+1
|
* bpo-45439: Move _PyObject_CallNoArgs() to pycore_call.h (GH-28895)Victor Stinner2021-10-121-1/+1
| | | | | | | * Move _PyObject_CallNoArgs() to pycore_call.h (internal C API). * _ssl, _sqlite and _testcapi extensions now call the public PyObject_CallNoArgs() function, rather than _PyObject_CallNoArgs(). * _lsprof extension is now built with Py_BUILD_CORE_MODULE macro defined to get access to internal _PyObject_CallNoArgs().
* Fix typos in the Modules directory (GH-28761)Christian Clauss2021-10-071-1/+1
|
* bpo-41710: Add private _PyDeadline_Get() function (GH-28674)Victor Stinner2021-10-011-10/+10
| | | | | | | | Add a private C API for deadlines: add _PyDeadline_Init() and _PyDeadline_Get() functions. * Add _PyTime_Add() and _PyTime_Mul() functions which compute t1+t2 and t1*t2 and clamp the result on overflow. * _PyTime_MulDiv() now uses _PyTime_Add() and _PyTime_Mul().
* bpo-45163: Haiku build fix. (GH-28269)David CARLIER2021-09-111-1/+1
| | | | | | linkage issues mainly for shared libs and missing system library, also little nit into the signal extension as strsignal returns a constant in this platform.
* bpo-44590: Lazily allocate frame objects (GH-27077)Mark Shannon2021-07-261-7/+12
| | | | | | | | | | | | | | * Convert "specials" array to InterpreterFrame struct, adding f_lasti, f_state and other non-debug FrameObject fields to it. * Refactor, calls pushing the call to the interpreter upward toward _PyEval_Vector. * Compute f_back when on thread stack, only filling in value when frame object outlives stack invocation. * Move ownership of InterpreterFrame in generator from frame object to generator object. * Do not create frame objects for Python calls. * Do not create frame objects for generators.
* bpo-43963: Add _signal module state (GH-25676)Victor Stinner2021-04-281-84/+153
| | | | | | | | | | | | | * Add signal_state_t structure and signal_global_state variable. * Add a module state to the _signal module. * Move and rename variables: * DefaultHandler becomes state->default_handler * IgnoreHandler becomes state->ignore_handler * sigint_event becomes state->sigint_event * ItimerError becomes modstate->itimer_error * Rename SetHandler() to set_handler() to be consistent with get_handler().
* bpo-43963: Fix import _signal in subinterpreters (GH-25674)Victor Stinner2021-04-271-27/+41
| | | | | | | Importing the _signal module in a subinterpreter has no longer side effects. signal_module_exec() no longer modifies Handlers and no longer attempts to set SIGINT signal handler in subinterpreters.
* bpo-43356: Allow passing a signal number to interrupt_main() (GH-24755)Antoine Pitrou2021-03-111-30/+45
| | | | Also introduce a new C API ``PyErr_SetInterruptEx(int signum)``.
* bpo-43406: Fix possible race condition where ``PyErr_CheckSignals`` tries to ↵Antoine Pitrou2021-03-051-1/+25
| | | | | | execute a non-Python signal handler (GH-24756) We can receive signals (at the C level, in `trip_signal()` in signalmodule.c) while `signal.signal` is being called to modify the corresponding handler. Later when `PyErr_CheckSignals()` is called to handle the given signal, the handler may be a non-callable object and would raise a cryptic asynchronous exception.
* bpo-31904: Support signal module on VxWorks (GH-23391)pxinwr2020-11-301-0/+4
|
* bpo-41713: Port _signal module to multi-phase init (GH-23355)Victor Stinner2020-11-171-16/+17
| | | | | | Port the _signal extension module to the multi-phase initialization API (PEP 489). Co-Authored-By: Mohamed Koubaa <koubaa.m@gmail.com>
* bpo-41686: Move _Py_RestoreSignals() to signalmodule.c (GH-23353)Victor Stinner2020-11-171-0/+23
|
* bpo-41686: Refactor signal_exec() (GH-23346)Victor Stinner2020-11-171-158/+125
| | | | | | * Add signal_add_constants() function and add ADD_INT_MACRO macro. * The Python SIGINT handler is now installed at the end of signal_exec(). * Use Py_NewRef().
* bpo-41686: Always create the SIGINT event on Windows (GH-23344)Victor Stinner2020-11-171-53/+87
| | | | | | | | | | | | | | bpo-41686, bpo-41713: On Windows, the SIGINT event, _PyOS_SigintEvent(), is now created even if Python is configured to not install signal handlers (PyConfig.install_signal_handlers=0 or Py_InitializeEx(0)). Changes: * Move global variables initialization from signal_exec() to _PySignal_Init() to clarify that they are global variables cleared by _PySignal_Fini(). * _PySignal_Fini() now closes sigint_event. * IntHandler is no longer a global variable.
* bpo-41713: Remove PyOS_InitInterrupts() function (GH-23342)Victor Stinner2020-11-171-12/+25
| | | | | | | Remove the undocumented PyOS_InitInterrupts() C function. * Rename PyOS_InitInterrupts() to _PySignal_Init(). It now installs other signal handlers, not only SIGINT. * Rename PyOS_FiniInterrupts() to _PySignal_Fini()
* bpo-42006: Stop using PyDict_GetItem, PyDict_GetItemString and ↵Serhiy Storchaka2020-10-261-2/+1
| | | | | | | | | | | _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-41713: _signal doesn't use multi-phase init (GH-22087)Victor Stinner2020-09-041-7/+13
| | | | | Partially revert commit 71d1bd9569c8a497e279f2fea6fe47cd70a87ea3: don't use multi-phase initialization (PEP 489) for the _signal extension module.
* bpo-1635741: Port _signal module to multi-phase init (PEP 489) (GH-22049)Mohamed Koubaa2020-09-031-82/+86
|
* bpo-41675: Modernize siginterrupt calls (GH-22028)Pablo Galindo2020-09-021-1/+13
| | | | | | siginterrupt is deprecated: ./Modules/signalmodule.c:667:5: warning: ‘siginterrupt’ is deprecated: Use sigaction with SA_RESTART instead [-Wdeprecated-declarations] 667 | if (siginterrupt(signalnum, flag)<0) {
* bpo-41146: Convert signal.default_int_handler() to Argument Clinic (GH-21197)Serhiy Storchaka2020-07-121-8/+15
|
* bpo-40826: Add _PyOS_InterruptOccurred(tstate) function (GH-20599)Victor Stinner2020-06-031-2/+12
| | | | | | | | | | | | my_fgets() now calls _PyOS_InterruptOccurred(tstate) to check for pending signals, rather calling PyOS_InterruptOccurred(). my_fgets() is called with the GIL released, whereas PyOS_InterruptOccurred() must be called with the GIL held. test_repl: use text=True and avoid SuppressCrashReport in test_multiline_string_parsing(). Fix my_fgets() on Windows: fgets(fp) does crash if fileno(fp) is closed.
* PyOS_AfterFork_Child() uses PyStatus (GH-20596)Victor Stinner2020-06-021-3/+8
| | | | | | | | PyOS_AfterFork_Child() helper functions now return a PyStatus: PyOS_AfterFork_Child() is now responsible to handle errors. * Move _PySignal_AfterFork() to the internal C API * Add #ifdef HAVE_FORK on _PyGILState_Reinit(), _PySignal_AfterFork() and _PyInterpreterState_DeleteExceptMain().
* bpo-40826: PyOS_InterruptOccurred() requires GIL (GH-20578)Victor Stinner2020-06-011-2/+3
| | | | PyOS_InterruptOccurred() now fails with a fatal error if it is called with the GIL released.
* bpo-40268: Remove explicit pythread.h includes (#19529)Victor Stinner2020-04-151-2/+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 Stinner2020-04-141-2/+2
| | | | | | | 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-40082: trip_signal() uses the main interpreter (GH-19441)Victor Stinner2020-04-081-15/+12
| | | | | | | | | | | | | | | | | | | | | | Fix the signal handler: it now always uses the main interpreter, rather than trying to get the current Python thread state. The following function now accepts an interpreter, instead of a Python thread state: * _PyEval_SignalReceived() * _Py_ThreadCanHandleSignals() * _PyEval_AddPendingCall() * COMPUTE_EVAL_BREAKER() * SET_GIL_DROP_REQUEST(), RESET_GIL_DROP_REQUEST() * SIGNAL_PENDING_CALLS(), UNSIGNAL_PENDING_CALLS() * SIGNAL_PENDING_SIGNALS(), UNSIGNAL_PENDING_SIGNALS() * SIGNAL_ASYNC_EXC(), UNSIGNAL_ASYNC_EXC() Py_AddPendingCall() now uses the main interpreter if it fails to the current Python thread state. Convert _PyThreadState_GET() and PyInterpreterState_GET_UNSAFE() macros to static inline functions.
* bpo-38644: Pass tstate explicitly in signalmodule.c (GH-19184)Victor Stinner2020-03-261-63/+89
| | | | PyOS_InterruptOccurred() now checks _Py_ThreadCanHandleSignals() before checking if SIGINT is tripped.
