* bpo-1635741: Port _warnings to the multi-phase init (GH-23379)Victor Stinner2020-11-181-40/+30
| | | | Port the _warnings extension module to the multi-phase initialization API (PEP 489).
* bpo-40998: Fix a refleak in create_filter() (GH-23365)Victor Stinner2020-11-181-3/+5
|
* bpo-42260: Initialize time and warnings earlier at startup (GH-23249)Victor Stinner2020-11-121-23/+7
| | | | | | | | | | * Call _PyTime_Init() and _PyWarnings_InitState() earlier during the Python initialization. * Inline _PyImportHooks_Init() into _PySys_InitCore(). * The _warnings initialization function no longer call _PyWarnings_InitState() to prevent resetting filters_version to 0. * _PyWarnings_InitState() now returns an int and no longer clear the state in case of error (it's done anyway at Python exit). * Rework init_importlib(), fix refleaks on errors.
* bpo-1635741: Fix ref leak in _PyWarnings_Init() error path (GH-23151)Victor Stinner2020-11-041-8/+3
| | | | | | Replace PyModule_AddObject() with PyModule_AddObjectRef() in the _warnings module to fix a reference leak on error. Use also PyModule_AddObjectRef() in importdl.c.
* bpo-26789: Fix logging.FileHandler._open() at exit (GH-23053)Victor Stinner2020-11-021-1/+1
| | | | | | | | | | | | | | | | | | | The logging.FileHandler class now keeps a reference to the builtin open() function to be able to open or reopen the file during Python finalization. Fix errors like: Exception ignored in: (...) Traceback (most recent call last): (...) File ".../logging/__init__.py", line 1463, in error File ".../logging/__init__.py", line 1577, in _log File ".../logging/__init__.py", line 1587, in handle File ".../logging/__init__.py", line 1649, in callHandlers File ".../logging/__init__.py", line 948, in handle File ".../logging/__init__.py", line 1182, in emit File ".../logging/__init__.py", line 1171, in _open NameError: name 'open' is not defined
* bpo-42161: Use _PyLong_GetZero() and _PyLong_GetOne() (GH-22995)Victor Stinner2020-10-271-2/+3
| | | | Use _PyLong_GetZero() and _PyLong_GetOne() in Objects/ and Python/ directories.
* bpo-39465: Use _PyInterpreterState_GET() (GH-20788)Victor Stinner2020-06-101-6/+6
| | | | | | | | | | | | Replace _PyThreadState_GET() with _PyInterpreterState_GET() in: * get_small_int() * gcmodule.c: add also get_gc_state() function * _PyTrash_deposit_object() * _PyTrash_destroy_chain() * warnings_get_state() * Py_GetRecursionLimit() Cleanup listnode.c: add 'parser' variable.
* bpo-40421: Add PyFrame_GetBack() function (GH-19765)Victor Stinner2020-04-291-6/+12
| | | | | | New PyFrame_GetBack() function: get the frame next outer frame. Replace frame->f_back with PyFrame_GetBack(frame) in most code but frameobject.c, ceval.c and genobject.c.
* bpo-40429: PyFrame_GetCode() now returns a strong reference (GH-19773)Victor Stinner2020-04-281-1/+5
|
* bpo-40429: PyFrame_GetCode() result cannot be NULL (GH-19772)Victor Stinner2020-04-281-4/+0
| | | Add frame_nslots() to factorize duplicate code.
* bpo-40421: Add PyFrame_GetCode() function (GH-19757)Victor Stinner2020-04-281-5/+13
| | | | | | | | | 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-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-40268: Include explicitly pycore_interp.h (GH-19505)Victor Stinner2020-04-141-0/+1
| | | | pycore_pystate.h no longer includes pycore_interp.h: it's now included explicitly in files accessing PyInterpreterState.
* bpo-39943: Add the const qualifier to pointers on non-mutable PyUnicode ↵Serhiy Storchaka2020-04-111-2/+2
| | | | data. (GH-19345)
* bpo-32591: _PyErr_WarnUnawaitedCoroutine() sets source (GH-19247)Victor Stinner2020-03-311-3/+20
| | | | | | | | The _PyErr_WarnUnawaitedCoroutine() fallback now also sets the coroutine object as the source of the warning, as done by the Python implementation warnings._warn_unawaited_coroutine(). Moreover, don't truncate the coroutine name: Python supports arbitrary string length to format the message.
* bpo-39585: Delete a pending comment in _warning.c (GH-18414)Hai Shi2020-03-141-1/+2
|
* bpo-39831: Remove outdated comment. (GH-18764)Serhiy Storchaka2020-03-031-3/+1

|
* bpo-39796: Fix _warnings module initialization (GH-18739)Victor Stinner2020-03-021-13/+24
| | | | | | | | | * Add _PyWarnings_InitState() which only initializes the _warnings module state (tstate->interp->warnings) without creating a module object * Py_InitializeFromConfig() now calls _PyWarnings_InitState() instead of _PyWarnings_Init() * Rename also private functions of _warnings.c to avoid confusion between the public C API and the private C API.
* bpo-39245: Switch to public API for Vectorcall (GH-18460)Petr Viktorin2020-02-111-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The bulk of this patch was generated automatically with: for name in \ PyObject_Vectorcall \ Py_TPFLAGS_HAVE_VECTORCALL \ PyObject_VectorcallMethod \ PyVectorcall_Function \ PyObject_CallOneArg \ PyObject_CallMethodNoArgs \ PyObject_CallMethodOneArg \ ; do echo $name git grep -lwz _$name | xargs -0 sed -i "s/\b_$name\b/$name/g" done old=_PyObject_FastCallDict new=PyObject_VectorcallDict git grep -lwz $old | xargs -0 sed -i "s/\b$old\b/$new/g" and then cleaned up: - Revert changes to in docs & news - Revert changes to backcompat defines in headers - Nudge misaligned comments
* bpo-39573: Use Py_TYPE() macro in Python and Include directories (GH-18391)Victor Stinner2020-02-071-2/+2
| | | Replace direct access to PyObject.ob_type with Py_TYPE().
* bpo-39487: Merge duplicated _Py_IDENTIFIER identifiers in C code (GH-18254)Hai Shi2020-01-301-3/+2
| | | Moving repetitive `_Py_IDENTIFIER` instances to a global location helps identify them more easily in regards to sub-interpreter support.
* bpo-38644: Add _PyObject_Call() (GH-17089)Victor Stinner2019-11-141-3/+5
| | | | | | | | | | * Add pycore_call.h internal header file. * Add _PyObject_Call(): PyObject_Call() with tstate * Add _PyObject_CallNoArgTstate(): _PyObject_CallNoArg() with tstate * Add _PyObject_FastCallDictTstate(): _PyObject_FastCallDict() with tstate * _PyObject_Call_Prepend() now takes tstate * Replace _PyObject_FastCall() calls with _PyObject_VectorcallTstate() calls
* Fix typo in _warnings.warn_explicit() docstring (GH-16625)Hansraj Das2019-10-081-1/+1

* bpo-37483: add _PyObject_CallOneArg() function (#14558)Jeroen Demeyer2019-07-041-4/+4
|
* bpo-36737: Use the module state C-API for warnings. (gh-13159)Eric Snow2019-05-101-119/+198
|
* bpo-36724: Add _PyWarnings_Fini() (#12963)Victor Stinner2019-04-261-16/+27
| | | | | | | | | | Py_FinalizeEx() now clears _PyRuntime.warnings variables and _PyRuntime.exitfuncs. Changes: * Add _PyWarnings_Fini(): called by Py_FinalizeEx() * call_ll_exitfuncs() now clears _PyRuntime.exitfuncs while iterating on it (on backward order).
* bpo-35459: Use PyDict_GetItemWithError() instead of PyDict_GetItem(). (GH-11112)Serhiy Storchaka2019-02-251-5/+16

* bpo-35454: Fix miscellaneous minor issues in error handling. (#11077)Serhiy Storchaka2018-12-111-1/+5
| | | | | | * bpo-35454: Fix miscellaneous minor issues in error handling. * Fix a null pointer dereference.
* bpo-33012: Fix invalid function cast warnings with gcc 8. (GH-6749)Serhiy Storchaka2018-11-271-1/+1
| | | | | | Fix invalid function cast warnings with gcc 8 for method conventions different from METH_NOARGS, METH_O and METH_VARARGS excluding Argument Clinic generated code.
* bpo-35081: Rename internal headers (GH-10275)Victor Stinner2018-11-121-1/+1
| | | | | | | | | | | | | | Rename Include/internal/ headers: * pycore_hash.h -> pycore_pyhash.h * pycore_lifecycle.h -> pycore_pylifecycle.h * pycore_mem.h -> pycore_pymem.h * pycore_state.h -> pycore_pystate.h Add missing headers to Makefile.pre.in and PCbuild: * pycore_condvar.h. * pycore_hamt.h * pycore_pyhash.h
* bpo-35081: Add _PyThreadState_GET() internal macro (GH-10266)Victor Stinner2018-11-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | If Py_BUILD_CORE is defined, the PyThreadState_GET() macro access _PyRuntime which comes from the internal pycore_state.h header. Public headers must not require internal headers. Move PyThreadState_GET() and _PyInterpreterState_GET_UNSAFE() from Include/pystate.h to Include/internal/pycore_state.h, and rename PyThreadState_GET() to _PyThreadState_GET() there. The PyThreadState_GET() macro of pystate.h is now redefined when pycore_state.h is included, to use the fast _PyThreadState_GET(). Changes: * Add _PyThreadState_GET() macro * Replace "PyThreadState_GET()->interp" with _PyInterpreterState_GET_UNSAFE() * Replace PyThreadState_GET() with _PyThreadState_GET() in internal C files (compiled with Py_BUILD_CORE defined), but keep PyThreadState_GET() in the public header files. * _testcapimodule.c: replace PyThreadState_GET() with PyThreadState_Get(); the module is not compiled with Py_BUILD_CORE defined. * pycore_state.h now requires Py_BUILD_CORE to be defined.
* bpo-35081: Add pycore_ prefix to internal header files (GH-10263)Victor Stinner2018-10-311-1/+1
| | | | | | | | | | | | | | | | | | | | * Rename Include/internal/ header files: * pyatomic.h -> pycore_atomic.h * ceval.h -> pycore_ceval.h * condvar.h -> pycore_condvar.h * context.h -> pycore_context.h * pygetopt.h -> pycore_getopt.h * gil.h -> pycore_gil.h * hamt.h -> pycore_hamt.h * hash.h -> pycore_hash.h * mem.h -> pycore_mem.h * pystate.h -> pycore_state.h * warnings.h -> pycore_warnings.h * PCbuild project, Makefile.pre.in, Modules/Setup: add the Include/internal/ directory to the search paths of header files. * Update includes. For example, replace #include "internal/mem.h" with #include "pycore_mem.h".
* closes bpo-34646: Remove PyAPI_* macros from declarations. (GH-9218)Benjamin Peterson2018-09-121-1/+1
|
* bpo-34301: Add _PyInterpreterState_Get() helper function (GH-8592)Victor Stinner2018-08-031-2/+2
| | | | sys_setcheckinterval() now uses a local variable to parse arguments, before writing into interp->check_interval.
* bpo-33375: Fix GCC warning in Python/_warnings.c (GH-7556)Zackery Spytz2018-06-091-1/+0
| | | _Py_IDENTIFIER(argv) is now unused.
* bpo-33375: Get filename for warnings from frame.f_code.co_filename (GH-6622)Thomas Kluyver2018-06-081-66/+4
| | | More consistent with how other parts of Python find the filename (e.g. tracebacks and pdb).
* bpo-33509: Fix _warnings for module_globals=None (#6833)Victor Stinner2018-05-151-1/+8
| | | Don't crash on warnings.warn_explicit() if module_globals is not a dict.
* bpo-32591: fix abort in _PyErr_WarnUnawaitedCoroutine during shutdown (#5337)Nathaniel J. Smith2018-01-261-0/+7
| | | | | | | | | | | | | | | | | | When an unawaited coroutine is collected very late in shutdown -- like, during the final GC at the end of PyImport_Cleanup -- then it was triggering an interpreter abort, because we'd try to look up the "warnings" module and not only was it missing (we were prepared for that), but the entire module system was missing (which we were not prepared for). I've tried to fix this at the source, by making the utility function get_warnings_attr robust against this in general. Note that it already has the convention that it can return NULL without setting an error, which is how it signals that the attribute it was asked to fetch is missing, and that all callers already check for NULL returns. There's a similar check for being late in shutdown at the top of warn_explicit, which might be unnecessary after this fix, but I'm not sure so I'm going to leave it.
* bpo-32571: Avoid raising unneeded AttributeError and silencing it in C code ↵Serhiy Storchaka2018-01-251-8/+2
| | | | | (GH-5222) Add two new private APIs: _PyObject_LookupAttr() and _PyObject_LookupAttrId()
* bpo-32591: Fix PyExc_WarnFormat call (follow-up commit) (#5263)Yury Selivanov2018-01-221-5/+4
| | | | | The previous version was correct in terms of behaviour, but checking the return value of PyErr_WarnFormat allows to avoid calling PyErr_Occurred and silences the coverity alarm.
* bpo-32591: Add native coroutine origin tracking (#5250)Nathaniel J. Smith2018-01-211-0/+47
| | | | | | * Add coro.cr_origin and sys.set_coroutine_origin_tracking_depth * Use coroutine origin information in the unawaited coroutine warning * Stop using set_coroutine_wrapper in asyncio debug mode * In BaseEventLoop.set_debug, enable debugging in the correct thread
* bpo-31975 (PEP 565): Show DeprecationWarning in __main__ (GH-4458)Nick Coghlan2018-01-081-7/+33
| | | | | | | | | | | | | - primary change is to add a new default filter entry for 'default::DeprecationWarning:__main__' - secondary change is an internal one to cope with plain strings in the warning module's internal filter list (this avoids the need to create a compiled regex object early on during interpreter startup) - assorted documentation updates, including many more examples of configuring the warnings settings - additional tests to ensure that both the pure Python and the C accelerated warnings modules have the expected default configuration
* bpo-32030: Fix compiler warnings (#4921)Victor Stinner2017-12-191-13/+4
| | | | | | | | | | | Fix compiler warnings in Py_FinalizeEx(): only define variables if they are needed, add #ifdef. Other cleanup changes: * _PyWarnings_InitWithConfig() is no more needed: call _PyWarnings_Init() instead. * Inline pymain_init_main_interpreter() in its caller. This subfunction is no more justifed.
* bpo-32230: Set sys.warnoptions with -X dev (#4820)Victor Stinner2017-12-121-51/+22
| | | | | | | | | | | | | | Rather than supporting dev mode directly in the warnings module, this instead adjusts the initialisation code to add an extra 'default' entry to sys.warnoptions when dev mode is enabled. This ensures that dev mode behaves *exactly* as if `-Wdefault` had been passed on the command line, including in the way it interacts with `sys.warnoptions`, and with other command line flags like `-bb`. Fix also bpo-20361: have -b & -bb options take precedence over any other warnings options. Patch written by Nick Coghlan, with minor modifications of Victor Stinner.
* bpo-27535: Fix memory leak with warnings ignore (#4489)Victor Stinner2017-11-271-4/+9
| | | | | | | The warnings module doesn't leak memory anymore in the hidden warnings registry for the "ignore" action of warnings filters. The warn_explicit() function doesn't add the warning key to the registry anymore for the "ignore" action.
* bpo-32089: Use default action for ResourceWarning (#4584)Victor Stinner2017-11-271-3/+2
| | | | | In development and debug mode, use the "default" action, rather than the "always" action, for ResourceWarning in the default warnings filters.
* bpo-27535: Cleanup create_filter() (#4516)Victor Stinner2017-11-231-38/+18
| | | | | create_filter() now expects the action as a _Py_Identifier which avoids string comparison, and more important, to avoid handling the "unknown action" annoying case.
