* bpo-42260: Initialize time and warnings earlier at startup (GH-23249)Victor Stinner2020-11-121-37/+0
| | | | | | | | | | * 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-42208: Move _PyImport_Cleanup() to pylifecycle.c (GH-23040)Victor Stinner2020-10-301-227/+0
| | | | | Move _PyImport_Cleanup() to pylifecycle.c, rename it to finalize_modules(), split it (200 lines) into many smaller sub-functions and cleanup the code.
* bpo-42208: Pass tstate to _PyGC_CollectNoFail() (GH-23038)Victor Stinner2020-10-301-2/+2
| | | | | | | | | | | | Move private _PyGC_CollectNoFail() to the internal C API. Remove the private _PyGC_CollectIfEnabled() which was just an alias to the public PyGC_Collect() function since Python 3.8. Rename functions: * collect() => gc_collect_main() * collect_with_callback() => gc_collect_with_callback() * collect_generations() => gc_collect_generations()
* bpo-42152: Use PyDict_Contains and PyDict_SetDefault if appropriate. (GH-22986)Serhiy Storchaka2020-10-261-10/+14
| | | | | | | If PyDict_GetItemWithError is only used to check whether the key is in dict, it is better to use PyDict_Contains instead. And if it is used in combination with PyDict_SetItem, PyDict_SetDefault can replace the combination.
* bpo-41993: Fix possible issues in remove_module() (GH-22631)Serhiy Storchaka2020-10-111-10/+13
| | | | | | * PyMapping_HasKey() is not safe because it silences all exceptions and can return incorrect result. * Informative exceptions from PyMapping_DelItem() are overridden with RuntimeError and the original exception raised before calling remove_module() is lost. * There is a race condition between PyMapping_HasKey() and PyMapping_DelItem().
* bpo-40232: _PyImport_ReInitLock() can now safely use its lock (GH-20597)Victor Stinner2020-06-021-5/+1
| | | | | Since _PyImport_ReInitLock() now calls _PyThread_at_fork_reinit() on the import lock, the lock is now in a known state: unlocked. It became safe to acquire it after fork.
* PyOS_AfterFork_Child() uses PyStatus (GH-20596)Victor Stinner2020-06-021-6/+7
| | | | | | | | 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-40417: Fix deprecation warning in PyImport_ReloadModule (GH-19750)Robert Rouhani2020-05-011-7/+7
| | | | | I can add another commit with the new test case I wrote to verify that the warning was being printed before my change, stopped printing after my change, and that the function does not return null after my change. Automerge-Triggered-By: @brettcannon
* bpo-40412: Nullify inittab_copy during finalization (GH-19746)Gregory Szorc2020-05-011-0/+1
| | | | | | | | | Otherwise we leave a dangling pointer to free'd memory. If we then initialize a new interpreter in the same process and call PyImport_ExtendInittab, we will (likely) crash when calling PyMem_RawRealloc(inittab_copy, ...) since the pointer address is bogus.

* bpo-40429: PyFrame_GetCode() now returns a strong reference (GH-19773)Victor Stinner2020-04-281-0/+1
|
* bpo-40421: Add PyFrame_GetCode() function (GH-19757)Victor Stinner2020-04-281-2/+1
| | | | | | | | | 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 unused osdefs.h includes (GH-19532)Victor Stinner2020-04-151-1/+0
| | | When the include is needed, add required symbol in a comment.
* bpo-40268: Remove unused pycore_pymem.h includes (GH-19531)Victor Stinner2020-04-151-1/+1
|
* 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 Stinner2020-04-141-2/+2
|
* bpo-40268: Rename _PyInterpreterState_GET_UNSAFE() (GH-19509)Victor Stinner2020-04-141-3/+3
| | | | | | | 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-40268: Add _PyInterpreterState_GetConfig() (GH-19492)Victor Stinner2020-04-131-6/+6
| | | | | | | | Don't access PyInterpreterState.config member directly anymore, but use new functions: * _PyInterpreterState_GetConfig() * _PyInterpreterState_SetConfig() * _Py_GetConfig()
* bpo-39943: Remove unnecessary casts in import.c that remove constness (GH-19209)Andy Lester2020-03-301-2/+2

* bpo-39882: Add _Py_FatalErrorFormat() function (GH-19157)Victor Stinner2020-03-251-3/+3
|
* bpo-39947: Use _PyInterpreterState_GET_UNSAFE() (GH-18978)Victor Stinner2020-03-131-2/+2
| | | | | | | Replace _PyInterpreterState_Get() function call with _PyInterpreterState_GET_UNSAFE() macro which is more efficient but don't check if tstate or interp is NULL. _Py_GetConfigsAsDict() now uses _PyThreadState_GET().
* bpo-39882: Py_FatalError() logs the function name (GH-18819)Victor Stinner2020-03-061-3/+2
| | | | | | | | | | | | The Py_FatalError() function is replaced with a macro which logs automatically the name of the current function, unless the Py_LIMITED_API macro is defined. Changes: * Add _Py_FatalErrorFunc() function. * Remove the function name from the message of Py_FatalError() calls which included the function name. * Update tests.
* bpo-39245: Switch to public API for Vectorcall (GH-18460)Petr Viktorin2020-02-111-1/+1

* bpo-38076 Clear the interpreter state only after clearing module globals ↵Eddie Elizondo2020-02-041-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (GH-18039) Currently, during runtime destruction, `_PyImport_Cleanup` is clearing the interpreter state before clearing out the modules themselves. This leads to a segfault on modules that rely on the module state to clear themselves up. For example, let's take the small snippet added in the issue by @DinoV : ``` import _struct class C: def __init__(self): self.pack = _struct.pack def __del__(self): self.pack('I', -42) _struct.x = C() ``` The module `_struct` uses the module state to run `pack`. Therefore, the module state has to be alive until after the module has been cleared out to successfully run `C.__del__`. This happens at line 606, when `_PyImport_Cleanup` calls `_PyModule_Clear`. In fact, the loop that calls `_PyModule_Clear` has in its comments: > Now, if there are any modules left alive, clear their globals to minimize potential leaks. All C extension modules actually end up here, since they are kept alive in the interpreter state. That means that we can't clear the module state (which is used by C Extensions) before we run that loop. Moving `_PyInterpreterState_ClearModules` until after it, fixes the segfault in the code snippet. Finally, this updates a test in `io` to correctly assert the error that it now throws (since it now finds the io module state). The test that uses this is: `test_create_at_shutdown_without_encoding`. Given this test is now working is a proof that the module state now stays alive even when `__del__` is called at module destruction time. Thus, I didn't add a new tests for this. https://bugs.python.org/issue38076
* bpo-39487: Merge duplicated _Py_IDENTIFIER identifiers in C code (GH-18254)Hai Shi2020-01-301-4/+3
| | | Moving repetitive `_Py_IDENTIFIER` instances to a global location helps identify them more easily in regards to sub-interpreter support.
* bpo-38960: DTrace build fix for FreeBSD. (GH-17451)David Carlier2020-01-281-2/+2
| | | | | | | | DTrace build fix for FreeBSD. - allowing passing an extra flag as it need to define the arch size. - casting some probe's arguments.
* bpo-38858: new_interpreter() reuses pycore_init_builtins() (GH-17351)Victor Stinner2019-11-221-11/+0
| | | | | | | | | new_interpreter() now calls _PyBuiltin_Init() to create the builtins module and calls _PyImport_FixupBuiltin(), rather than using _PyImport_FindBuiltin(tstate, "builtins"). pycore_init_builtins() is now responsible to initialize intepr->builtins_copy: inline _PyImport_Init() and remove this function.
* bpo-38858: _PyImport_FixupExtensionObject() handles subinterpreters (GH-17350)Victor Stinner2019-11-221-29/+41
| | | | | If _PyImport_FixupExtensionObject() is called from a subinterpreter, leave extensions unchanged and don't copy the module dictionary into def->m_base.m_copy.
* bpo-36854: gcmodule.c gets its state from tstate (GH-17285)Victor Stinner2019-11-201-1/+1
| | | | | | | | | * Add GCState type for readability * gcmodule.c now gets its gcstate from tstate * _PyGC_DumpShutdownStats() now expects tstate rather than runtime * Rename "state" to "gcstate" for readability: to avoid confusion between "state" and "tstate" for example. * collect() now only expects tstate: it gets gcstate from tstate. * Pass tstate to _PyErr_xxx() functions
* bpo-38353: Cleanup includes in the internal C API (GH-16548)Victor Stinner2019-10-021-0/+1
| | | | Use forward declaration of types to avoid includes in the internal C API. Add also comment to justify other includes.
* bpo-35943: Prevent PyImport_GetModule() from returning a ↵Joannah Nanjekye2019-09-111-23/+46

* bpo-37409: fix relative import with no parent (#14956)Ben Lewis2019-09-111-11/+13
| | | | | | | | | | | | | Relative imports use resolve_name to get the absolute target name, which first seeks the current module's absolute package name from the globals: If __package__ (and __spec__.parent) are missing then import uses __name__, truncating the last segment if the module is a submodule rather than a package __init__.py (which it guesses from whether __path__ is defined). The __name__ attempt should fail if there is no parent package (top level modules), if __name__ is '__main__' (-m entry points), or both (scripts). That is, if both __name__ has no subcomponents and the module does not seem to be a package __init__ module then import should fail.
* bpo-37444: Update differing exception between builtins and importlib (GH-14869)Ngalim Siregar2019-08-031-1/+1
| | | | | | | | | | Imports now raise `TypeError` instead of `ValueError` for relative import failures. This makes things consistent between `builtins.__import__` and `importlib.__import__` as well as using a more natural import for the failure. https://bugs.python.org/issue37444 Automerge-Triggered-By: @brettcannon
