* bpo-39511: PyThreadState_Clear() calls on_delete (GH-18296)Victor Stinner2020-02-011-3/+5
| | | | | | | | | | | | | | | | | | 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-38858: _PyImport_FixupExtensionObject() handles subinterpreters (GH-17350)Victor Stinner2019-11-221-16/+23
| | | | | 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-38858: Add _Py_IsMainInterpreter(tstate) (GH-17293)Victor Stinner2019-11-201-0/+6

* bpo-36854: Move _PyRuntimeState.gc to PyInterpreterState (GH-17287)Victor Stinner2019-11-201-1/+1
| | | | | * Rename _PyGC_InitializeRuntime() to _PyGC_InitState() * finalize_interp_clear() now also calls _PyGC_Fini() in subinterpreters (clear the GC state).
* bpo-36854: Clear the current thread later (GH-17279)Victor Stinner2019-11-201-23/+34
| | | | | | | | | | Clear the current thread later in the Python finalization. * The PyInterpreterState_Delete() function is now responsible to call PyThreadState_Swap(NULL). * The tstate_delete_common() function is now responsible to clear the "autoTSSKey" thread local storage and it only clears it once the thread state is fully cleared. It allows to still get the current thread from TSS in tstate_delete_common().
* bpo-38858: Factorize Py_EndInterpreter() code (GH-17273)Victor Stinner2019-11-201-2/+2
| | | | | | * Factorize code in common between Py_FinalizeEx() and Py_EndInterpreter(). * Py_EndInterpreter() now also calls _PyWarnings_Fini(). * Call _PyExc_Fini() and _PyGC_Fini() later in the finalization.
* bpo-36710: Add PyInterpreterState.runtime field (GH-17270)Victor Stinner2019-11-201-44/+28
| | | | | | | | | | | Add PyInterpreterState.runtime field: reference to the _PyRuntime global variable. This field exists to not have to pass runtime in addition to tstate to a function. Get runtime from tstate: tstate->interp->runtime. Remove "_PyRuntimeState *runtime" parameter from functions already taking a "PyThreadState *tstate" parameter. _PyGC_Init() first parameter becomes "PyThreadState *tstate".
* bpo-38631: Avoid Py_FatalError() in handle_legacy_finalizers() (GH-17266)Victor Stinner2019-11-201-1/+1
| | | | | * Rename _PyGC_Initialize() to _PyGC_InitializeRuntime() * Add _PyGC_Init(): initialize _PyRuntime.gc.garbage list * Call _PyGC_Init() before _PyTypes_Init()
* bpo-38266: Revert bpo-37878: Make PyThreadState_DeleteCurrent() Internal ↵Joannah Nanjekye2019-10-041-2/+8

* bpo-38304: PyConfig_InitPythonConfig() cannot fail anymore (GH-16509)Victor Stinner2019-10-011-8/+1
| | | | PyConfig_InitPythonConfig() and PyConfig_InitIsolatedConfig() no longer return PyStatus: they cannot fail anymore.
* bpo-38304: Remove PyConfig.struct_size (GH-16500) (GH-16508)Victor Stinner2019-10-011-6/+1
| | | | | | | For now, we'll rely on the fact that the config structures aren't covered by the stable ABI. We may revisit this in the future if we further explore the idea of offering a stable embedding API. (cherry picked from commit bdace21b769998396d0ccc8da99a8ca9b507bfdf)
* bpo-38304: Add PyConfig.struct_size (GH-16451)Victor Stinner2019-09-281-1/+7
| | | | | | | | | | | | | | | | | Add a new struct_size field to PyPreConfig and PyConfig structures to allow to modify these structures in the future without breaking the backward compatibility. * Replace private _config_version field with public struct_size field in PyPreConfig and PyConfig. * Public PyPreConfig_InitIsolatedConfig() and PyPreConfig_InitPythonConfig() return type becomes PyStatus, instead of void. * Internal _PyConfig_InitCompatConfig(), _PyPreConfig_InitCompatConfig(), _PyPreConfig_InitFromConfig(), _PyPreConfig_InitFromPreConfig() return type becomes PyStatus, instead of void. * Remove _Py_CONFIG_VERSION * Update the Initialization Configuration documentation.
* closes bpo-38124: Fix bounds check in PyState_AddModule. (GH-16007)Benjamin Peterson2019-09-121-8/+6
| | | | | The >=, checking whether a module index was in already in the module-by-index list, needed to be strict. Also, fold nested ifs into one and fix some bad spacing.

* bpo-36763: Add _PyPreConfig._config_init (GH-13481)Victor Stinner2019-05-221-2/+8
| | | | | | | | | | | | | | | | | | | * _PyPreConfig_GetGlobalConfig() and _PyCoreConfig_GetGlobalConfig() now do nothing if the configuration was not initialized with _PyPreConfig_InitCompatConfig() and _PyCoreConfig_InitCompatConfig() * Remove utf8_mode=-2 special case: use utf8_mode=-1 instead. * Fix _PyPreConfig_InitPythonConfig(): * isolated = 0 instead of -1 * use_environment = 1 instead of -1 * Rename _PyConfig_INIT to _PyConfig_INIT_COMPAT * Rename _PyPreConfig_Init() to _PyPreConfig_InitCompatConfig() * Rename _PyCoreConfig_Init() to _PyCoreConfig_InitCompatConfig() * PyInterpreterState_New() now uses _PyCoreConfig_InitPythonConfig() as default configuration, but it's very quickly overriden anyway. * _freeze_importlib.c uses _PyCoreConfig_SetString() to set program_name. * Cleanup preconfig_init_utf8_mode(): cmdline is always non-NULL.
* bpo-36763: Add _PyCoreConfig_InitPythonConfig() (GH-13388)Victor Stinner2019-05-171-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add new functions to get the Python interpreter behavior: * _PyPreConfig_InitPythonConfig() * _PyCoreConfig_InitPythonConfig() Add new functions to get an isolated configuration: * _PyPreConfig_InitIsolatedConfig() * _PyCoreConfig_InitIsolatedConfig() Replace _PyPreConfig_INIT and _PyCoreConfig_INIT with new functions _PyPreConfig_Init() and _PyCoreConfig_Init(). _PyCoreConfig: set configure_c_stdio and parse_argv to 0 by default to behave as Python 3.6 in the default configuration. _PyCoreConfig_Read() no longer sets coerce_c_locale_warn to 1 if it's equal to 0. coerce_c_locale_warn must now be set to -1 (ex: using _PyCoreConfig_InitPythonConfig()) to enable C locale coercion warning. Add unit tests for _PyCoreConfig_InitPythonConfig() and _PyCoreConfig_InitIsolatedConfig(). Changes: * Rename _PyCoreConfig_GetCoreConfig() to _PyPreConfig_GetCoreConfig() * Fix core_read_precmdline(): handle parse_argv=0 * Fix _Py_PreInitializeFromCoreConfig(): pass coreconfig.argv to _Py_PreInitializeFromPyArgv(), except if parse_argv=0
