* bpo-43760: Add PyThreadState_EnterTracing() (GH-28542)Victor Stinner2021-10-151-0/+24
| | | | | | | | | | Add PyThreadState_EnterTracing() and PyThreadState_LeaveTracing() functions to the limited C API to suspend and resume tracing and profiling. Add an unit test on the PyThreadState C API to _testcapi. Add also internal _PyThreadState_DisableTracing() and _PyThreadState_ResetTracing().
* bpo-41203: Replace Mac OS X and OS X with macOS (GH-28515)Serhiy Storchaka2021-09-221-3/+3
| | | | | | | Replace old names when they refer to actual versions of macOS. Keep historical names in references to older versions. Co-authored-by: Patrick Reader <_@pxeger.com>
* bpo-45019: Add a tool to generate list of modules to include for frozen ↵Eric Snow2021-08-301-1/+1
| | | | | | | modules (gh-27980) Frozen modules must be added to several files in order to work properly. Before this change this had to be done manually. Here we add a tool to generate the relevant lines in those files instead. This helps us avoid mistakes and omissions. https://bugs.python.org/issue45019
* bpo-44113: Deprecate old functions to config Python init (GH-26060)Victor Stinner2021-05-121-0/+32
| | | | | | | | | | | | | | | | | Deprecate the following functions to configure the Python initialization: * PySys_AddWarnOption() * PySys_AddWarnOptionUnicode() * PySys_AddXOption() * PySys_HasWarnOptions() * Py_SetPath() * Py_SetProgramName() * Py_SetPythonHome() * Py_SetStandardStreamEncoding() * _Py_SetProgramFullPath() Use the new PyConfig API of the Python Initialization Configuration instead (PEP 587).
* Docs: Remove stray semicolon in init.rst (GH-23974)Ken Jin2021-01-141-1/+1
| | | Removed stray semicolon which was causing the docs to render weirdly (it's the function right under the one [here](https://docs.python.org/3/c-api/init.html#c._PyInterpreterState_GetEvalFrameFunc)).
* bpo-42260: Fix _PyConfig_Read() if compute_path_config=0 (GH-23220)Victor Stinner2020-11-101-0/+36
| | | | | | | | | | | | | | | | | | | Fix _PyConfig_Read() if compute_path_config=0: use values set by Py_SetPath(), Py_SetPythonHome() and Py_SetProgramName(). Add compute_path_config parameter to _PyConfig_InitPathConfig(). The following functions now return NULL if called before Py_Initialize(): * Py_GetExecPrefix() * Py_GetPath() * Py_GetPrefix() * Py_GetProgramFullPath() * Py_GetProgramName() * Py_GetPythonHome() These functions no longer automatically computes the Python Path Configuration. Moreover, Py_SetPath() no longer computes program_full_path.
* bpo-42294: Add borrowed/strong reference to doc glossary (GH-23206)Victor Stinner2020-11-091-1/+1
| | | | | | Add "borrowed reference" and "strong reference" to the documentation glossary. Enhance also Py_INCREF() and Py_NewRef() documentation.
* bpo-42236: Enhance init and encoding documentation (GH-23109)Victor Stinner2020-11-021-2/+3
| | | | | | | | | | | | | | | | | | | | | Enhance the documentation of the Python startup, filesystem encoding and error handling, locale encoding. Add a new "Python UTF-8 Mode" section. * Add "locale encoding" and "filesystem encoding and error handler" to the glossary * Remove documentation from Include/cpython/initconfig.h: move it to Doc/c-api/init_config.rst. * Doc/c-api/init_config.rst: * Document command line options and environment variables * Document default values. * Add a new "Python UTF-8 Mode" section in Doc/library/os.rst. * Add warnings to Py_DecodeLocale() and Py_EncodeLocale() docs. * Document how Python selects the filesystem encoding and error handler at a single place: PyConfig.filesystem_encoding and PyConfig.filesystem_errors. * PyConfig: move orig_argv member at the right place.
* bpo-40204, doc: Fix syntax of C variables (GH-21846)Victor Stinner2020-08-131-24/+24
| | | | | | | | | | | | | | | For example, fix the following Sphinx 3 errors: Doc/c-api/buffer.rst:102: WARNING: Error in declarator or parameters Invalid C declaration: Expected identifier in nested name. [error at 5] void \*obj -----^ Doc/c-api/arg.rst:130: WARNING: Unparseable C cross-reference: 'PyObject*' Invalid C declaration: Expected end of definition. [error at 8] PyObject* --------^ The modified documentation is compatible with Sphinx 2 and Sphinx 3.
* bpo-40429: PyThreadState_GetFrame() returns a strong ref (GH-19781)Victor Stinner2020-04-291-3/+3
| | | | The PyThreadState_GetFrame() function now returns a strong reference to the frame.
* bpo-40421: Add PyFrame_GetCode() function (GH-19757)Victor Stinner2020-04-281-2/+4
| | | | | | | | | PyFrame_GetCode(frame): return a borrowed reference to the frame code. Replace frame->f_code with PyFrame_GetCode(frame) in most code, except in frameobject.c, genobject.c and ceval.c. Also add PyFrame_GetLineNumber() to the limited C API.
* bpo-40302: Replace PY_INT64_T with int64_t (GH-19573)Victor Stinner2020-04-171-1/+1
| | | | | | | | | * Replace PY_INT64_T with int64_t * Replace PY_UINT32_T with uint32_t * Replace PY_UINT64_T with uint64_t sha3module.c no longer checks if PY_UINT64_T is defined since it's always defined and uint64_t is always available on platforms supported by Python.
* bpo-38644: Make tstate more explicit inside pystate.c (GH-19182)Victor Stinner2020-03-261-0/+2
| | | | Fix PyInterpreterState_New(): Don't call PyErr_SetString() when there is no current Python thread state (if tstate is NULL).
* bpo-39947: Add PyThreadState_GetID() function (GH-19163)Victor Stinner2020-03-251-0/+9
| | | | Add PyThreadState_GetID() function: get the unique identifier of a Python thread state.
* bpo-39947: Add PyThreadState_GetFrame() function (GH-19092)Victor Stinner2020-03-201-0/+12
| | | | Add PyThreadState_GetFrame() function: get the current frame of a Python thread state.
* bpo-39984: Move pending calls to PyInterpreterState (GH-19066)Victor Stinner2020-03-191-0/+10
| | | | | | | | | | | | | | | | | 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-39947: Add PyThreadState_GetInterpreter() (GH-18981)Victor Stinner2020-03-131-5/+14
| | | | Add PyThreadState_GetInterpreter(tstate): get the interpreter of a Python thread state.
* bpo-39947: Add PyInterpreterState_Get() function (GH-18979)Victor Stinner2020-03-131-0/+12
| | | | | | * Rename _PyInterpreterState_Get() to PyInterpreterState_Get() and move it the limited C API. * Add _PyInterpreterState_Get() alias to PyInterpreterState_Get() for backward compatibility with Python 3.8.
* bpo-35370: Add _PyEval_SetTrace() function (GH-18975)Victor Stinner2020-03-131-0/+5
| | | | | | | | | * sys.settrace(), sys.setprofile() and _lsprof.Profiler.enable() now properly report PySys_Audit() error if "sys.setprofile" or "sys.settrace" audit event is denied. * Add _PyEval_SetProfile() and _PyEval_SetTrace() function: similar to PyEval_SetProfile() and PyEval_SetTrace() but take a tstate parameter and return -1 on error. * Add _PyObject_FastCallTstate() function.
* bpo-38500: Add _PyInterpreterState_SetEvalFrameFunc() (GH-17340)Victor Stinner2020-03-121-0/+26
| | | | | | | | | | | | PyInterpreterState.eval_frame function now requires a tstate (Python thread state) parameter. Add private functions to the C API to get and set the frame evaluation function: * Add tstate parameter to _PyFrameEvalFunction function type. * Add _PyInterpreterState_GetEvalFrameFunc() and _PyInterpreterState_SetEvalFrameFunc() functions. * Add tstate parameter to _PyEval_EvalFrameDefault().
* bpo-39877: Deprecate PyEval_InitThreads() (GH-18892)Victor Stinner2020-03-101-5/+9
| | | | Deprecated PyEval_InitThreads() and PyEval_ThreadsInitialized(). Calling PyEval_InitThreads() now does nothing.
* bpo-39511: PyThreadState_Clear() calls on_delete (GH-18296)Victor Stinner2020-02-011-0/+4
| | | | | | | | | | | | | | | | | | PyThreadState.on_delete is a callback used to notify Python when a thread completes. _thread._set_sentinel() function creates a lock which is released when the thread completes. It sets on_delete callback to the internal release_sentinel() function. This lock is known as Threading._tstate_lock in the threading module. The release_sentinel() function uses the Python C API. The problem is that on_delete is called late in the Python finalization, when the C API is no longer fully working. The PyThreadState_Clear() function now calls the PyThreadState.on_delete callback. Previously, that happened in PyThreadState_Delete(). The release_sentinel() function is now called when the C API is still fully working.
* bpo-38631: Replace Py_FatalError() with assert() in ceval.c (GH-18279)Victor Stinner2020-01-301-1/+1
| | | | | | | Replace a few Py_FatalError() calls if tstate is NULL with assert(tstate != NULL) in ceval.c. PyEval_AcquireThread(), PyEval_ReleaseThread() and PyEval_RestoreThread() must never be called with a NULL tstate.
* bpo-39161: Document multi-phase init modules under Py_NewInterpreter() ↵Petr Viktorin2020-01-091-17/+35
| | | | | | | | | (GH-17896) \+ this also adds a stronger warning against sharing objects between (sub-)interpreters. https://bugs.python.org/issue39161
* bpo-39136: Fixed typos (GH-17720)Gurupad Hegde2019-12-281-1/+1
| | | | | funtion -> function; configuraton -> configuration; defintitions -> definitions; focusses -> focuses; necesarily -> necessarily; follwing -> following; Excape -> Escape,
* bpo-38816: Add notes in the C-API docs about fork in subinterpreters. (GH-17176)Eric Snow2019-11-151-1/+22
| | | | | | The C-API docs are a bit sparse on the interplay between C `fork()` and the CPython runtime. This change adds some more information on the subject. https://bugs.python.org/issue38816
* bpo-38600: NULL -> ``NULL``. (GH-17001)Serhiy Storchaka2019-10-301-1/+1
| | | Also fix some other formatting.
* bpo-38600: Change the mark up of NULL in the C API documentation. (GH-16950)Serhiy Storchaka2019-10-301-38/+38
| | | | Replace all *NULL* with ``NULL``.
* bpo-38266: Revert bpo-37878: Make PyThreadState_DeleteCurrent() Internal ↵Joannah Nanjekye2019-10-041-0/+8
| | | | | (GH-16558) Revert the removal of PyThreadState_DeleteCurrent() with documentation.
* bpo-38234: Py_SetPath() uses the program full path (GH-16357)Victor Stinner2019-09-241-2/+6
| | | | | | | Py_SetPath() now sets sys.executable to the program full path (Py_GetProgramFullPath()), rather than to the program name (Py_GetProgramName()). Fix also memory leaks in pathconfig_set_from_config().
* bpo-37363: Document internal audit events (GH-14663)Christian Heimes2019-09-121-1/+6
| | | | | | | | | Three internal cpython events were not documented, yet. Signed-off-by: Christian Heimes <christian@python.org> https://bugs.python.org/issue37363
* bpo-36763, doc: Add links in the new C API init doc (GH-15433)Victor Stinner2019-08-231-0/+2
|
* bpo-36487: Make C-API docs clear about what the main interpreter is. (gh-12666)Joannah Nanjekye2019-08-021-4/+12
|
* Doc: Replace the deprecated highlightlang directive by highlight. (#13377)Stéphane Wirtel2019-05-171-1/+1
| | | | highlightlang is deprecated since April 2018 in Sphinx. See https://github.com/sphinx-doc/sphinx/pull/4845
* bpo-36728: Remove PyEval_ReInitThreads documentation (GH-13282)Victor Stinner2019-05-131-7/+0
|
* bpo-36475: Finalize PyEval_AcquireLock() and PyEval_AcquireThread() properly ↵Joannah Nanjekye2019-04-291-0/+24
| | | | | | | | (GH-12667) PyEval_AcquireLock() and PyEval_AcquireThread() now terminate the current thread if called while the interpreter is finalizing, making them consistent with PyEval_RestoreThread(), Py_END_ALLOW_THREADS, and PyGILState_Ensure().
* bpo-36427: Document that PyEval_RestoreThread and PyGILState_Ensure can ↵Pablo Galindo2019-04-131-0/+12
| | | | | | | | terminate the calling thread (GH-12541) Calling these function from a thread when the runtime is finalizing will terminate the thread, even if the thread was not created by Python. Users can use _Py_IsFinalizing or sys.is_finalizing to check if the interpreter is in the process of being finalized before calling this function to avoid unwanted termination.
* bpo-36157:Document PyInterpreterState_Main() (GH-12238)Joannah Nanjekye2019-04-011-0/+5
| | | | | | | I have added documentation for `PyInterpreterState_Main()`. I chose to place it under Advanced Debugger Support together with similar functions like `PyInterpreterState_Head()`, `PyInterpreterState_Next(`), and `PyInterpreterState_ThreadHead()` . https://bugs.python.org/issue36157
* C API docs: Py_IsInitialized is always safe to call (GH-12630)Nick Coghlan2019-03-301-0/+1

| | | | | | Replace "Availability: xxx" with ".. availability:: xxx" in the doc. Original patch by Georg Brandl. Co-Authored-By: Georg Brandl <georg@python.org>
* bpo-31370: Remove references to threadless builds (#8805)Zackery Spytz2018-09-291-8/+8
| | | Support for threadless builds was removed in a6a4dc81.
* bpo-33042: Fix pre-initialization sys module configuration (GH-6157)Nick Coghlan2018-03-251-0/+3
| | | | | | | | | - new test case for pre-initialization of sys.warnoptions and sys._xoptions - restored ability to call these APIs prior to Py_Initialize - updated the docs for the affected APIs to make it clear they can be called before Py_Initialize - also enhanced the existing embedding test cases to check for expected settings in the sys module
* Make formatting of some return codes conforming to the general style. (#5587)Serhiy Storchaka2018-02-091-3/+3
|
* bpo-20891: Py_Initialize() now creates the GIL (#4700)Victor Stinner2018-01-291-40/+23
| | | | The GIL is no longer created "on demand" to fix a race condition when PyGILState_Ensure() is called in a non-Python thread.
* Fix PyTrace_RETURN documentation (GH-5384)Xiang Zhang2018-01-281-1/+1
| | | It will be triggered when propagating an exception.
