* bpo-43268: Pass interp rather than tstate to internal functions (GH-24580)Victor Stinner2021-02-191-3/+3
| | | | | | | | | | | | | | | Pass the current interpreter (interp) rather than the current Python thread state (tstate) to internal functions which only use the interpreter. Modified functions: * _PyXXX_Fini() and _PyXXX_ClearFreeList() functions * _PyEval_SignalAsyncExc(), make_pending_calls() * _PySys_GetObject(), sys_set_object(), sys_set_object_id(), sys_set_object_str() * should_audit(), set_flags_from_config(), make_flags() * _PyAtExit_Call() * init_stdio_encoding() * etc.
* bpo-42521: Add note about 'Python -d' only working on debug builds (GH-23607)Pablo Galindo2020-12-021-1/+2

* bpo-42260: Fix _PyConfig_Read() if compute_path_config=0 (GH-23220)Victor Stinner2020-11-101-2/+2
| | | | | | | | | | | | | | | | | | | 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-42260: Compute the path config in the main init (GH-23211)Victor Stinner2020-11-101-29/+18
| | | | | | | | | | | | | | | | | | | | | The path configuration is now computed in the "main" initialization. The core initialization no longer computes it. * Add _PyConfig_Read() function to read the configuration without computing the path configuration. * pyinit_core() no longer computes the path configuration: it is now computed by init_interp_main(). * The path configuration output members of PyConfig are now optional: * executable * base_executable * prefix * base_prefix * exec_prefix * base_exec_prefix * _PySys_UpdateConfig() now skips NULL strings in PyConfig. * _testembed: Rename test_set_config() to test_init_set_config() for consistency with other tests.
* bpo-42260: PyConfig_Read() only parses argv once (GH-23168)Victor Stinner2020-11-051-4/+7
| | | | | | | | | | | | The PyConfig_Read() function now only parses PyConfig.argv arguments once: PyConfig.parse_argv is set to 2 after arguments are parsed. Since Python arguments are strippped from PyConfig.argv, parsing arguments twice would parse the application options as Python options. * Rework the PyConfig documentation. * Fix _testinternalcapi.set_config() error handling. * SetConfigTests no longer needs parse_argv=0 when restoring the old configuration.
* bpo-42260: Add _PyConfig_FromDict() (GH-23167)Victor Stinner2020-11-051-57/+353
| | | | | | | * Rename config_as_dict() to _PyConfig_AsDict(). * Add 'module_search_paths_set' to _PyConfig_AsDict(). * Add _PyConfig_FromDict(). * Add get_config() and set_config() to _testinternalcapi. * Add config_check_consistency().
* bpo-42260: Add _PyInterpreterState_SetConfig() (GH-23158)Victor Stinner2020-11-041-1/+19
| | | | | | | | * Inline _PyInterpreterState_SetConfig(): replace it with _PyConfig_Copy(). * Add _PyErr_SetFromPyStatus() * Add _PyInterpreterState_GetConfigCopy() * Add a new _PyInterpreterState_SetConfig() function. * Add an unit which gets, modifies, and sets the config.
* bpo-42236: os.device_encoding() respects UTF-8 Mode (GH-23119)Victor Stinner2020-11-041-6/+7
| | | | On Unix, the os.device_encoding() function now returns 'UTF-8' rather than the device encoding if the Python UTF-8 Mode is enabled.
* bpo-42236: Enhance init and encoding documentation (GH-23109)Victor Stinner2020-11-021-0/+1
| | | | | | | | | | | | | | | | | | | | | 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-42236: Use UTF-8 encoding if nl_langinfo(CODESET) fails (GH-23086)Victor Stinner2020-11-011-9/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the nl_langinfo(CODESET) function returns an empty string, Python now uses UTF-8 as the filesystem encoding. In May 2010 (commit b744ba1d14c5487576c95d0311e357b707600b47), I modified Python to log a warning and use UTF-8 as the filesystem encoding (instead of None) if nl_langinfo(CODESET) returns an empty string. In August 2020 (commit 94908bbc1503df830d1d615e7b57744ae1b41079), I modified Python startup to fail with a fatal error and a specific error message if nl_langinfo(CODESET) returns an empty string. The intent was to prevent guessing the encoding and also investigate user configuration where this case happens. In 10 years (2010 to 2020), I saw zero user report about the error message related to nl_langinfo(CODESET) returning an empty string. Today, UTF-8 became the defacto standard and it's safe to make the assumption that the user expects UTF-8. For example, nl_langinfo(CODESET) can return an empty string on macOS if the LC_CTYPE locale is not supported, and UTF-8 is the default encoding on macOS. While this change is likely to not affect anyone in practice, it should make UTF-8 lover happy ;-) Rewrite also the documentation explaining how Python selects the filesystem encoding and error handler.
* bpo-42236: Enhance _locale._get_locale_encoding() (GH-23083)Victor Stinner2020-11-011-34/+13
| | | | | | | | | * Rename _Py_GetLocaleEncoding() to _Py_GetLocaleEncodingObject() * Add _Py_GetLocaleEncoding() which returns a wchar_t* string to share code between _Py_GetLocaleEncodingObject() and config_get_locale_encoding(). * _Py_GetLocaleEncodingObject() now decodes nl_langinfo(CODESET) from the current locale encoding with surrogateescape, rather than using UTF-8.
* bpo-42208: Add _Py_GetLocaleEncoding() (GH-23050)Victor Stinner2020-10-311-61/+64
| | | | | | | | _io.TextIOWrapper no longer calls getpreferredencoding(False) of _bootlocale to get the locale encoding, but calls _Py_GetLocaleEncoding() instead. Add config_get_fs_encoding() sub-function. Reorganize also config_get_locale_encoding() code.
* bpo-41819: Fix compiler warning in init_dump_ascii_wstr() (GH-22332)Samuel Marks2020-09-211-1/+1
| | | | | Fix the compiler warning: format specifies type `wint_t` (aka `int`) but the argument has type `unsigned int`
* Fix compiler warnings in init_dump_ascii_wstr() (GH-22150)Victor Stinner2020-09-091-1/+1
| | | | | | | | | | | | | | | | | Fix GCC 9.3 (using -O3) warnings on x86: initconfig.c: In function ‘init_dump_ascii_wstr’: initconfig.c:2679:34: warning: format ‘%lc’ expects argument of type ‘wint_t’, but argument 2 has type ‘wchar_t’ {aka ‘long int’} 2679 | PySys_WriteStderr("%lc", ch); initconfig.c:2682:38: warning: format ‘%x’ expects argument of type ‘unsigned int’, but argument 2 has type ‘wchar_t’ {aka ‘long int’} 2682 | PySys_WriteStderr("\\x%02x", ch); initconfig.c:2686:38: warning: format ‘%x’ expects argument of type ‘unsigned int’, but argument 2 has type ‘wchar_t’ {aka ‘long int’} 2686 | PySys_WriteStderr("\\U%08x", ch); initconfig.c:2690:38: warning: format ‘%x’ expects argument of type ‘unsigned int’, but argument 2 has type ‘wchar_t’ {aka ‘long int’} 2690 | PySys_WriteStderr("\\u%04x", ch);

* bpo-23427: Add sys.orig_argv attribute (GH-20729)Victor Stinner2020-06-291-8/+8
| | | | | | | Add sys.orig_argv attribute: the list of the original command line arguments passed to the Python executable. Rename also PyConfig._orig_argv to PyConfig.orig_argv and document it.
* bpo-40910: PyConfig_Clear() clears _orig_argv (GH-20886)Victor Stinner2020-06-151-0/+2
| | | bpo-40910, bpo-40953: PyConfig_Clear() clears _orig_argv.
* bpo-40939: Remove the old parser (GH-20768)Pablo Galindo2020-06-111-10/+0
| | | This commit removes the old parser, the deprecated parser module, the old parser compatibility flags and environment variables and all associated support code and documentation.
* bpo-40910: Export Py_GetArgcArgv() function (GH-20721)Victor Stinner2020-06-081-12/+18
| | | | | | | | | | | | Export explicitly the Py_GetArgcArgv() function to the C API and document the function. Previously, it was exported implicitly which no longer works since Python is built with -fvisibility=hidden. * Add PyConfig._orig_argv member. * Py_InitializeFromConfig() no longer calls _PyConfig_Write() twice. * PyConfig_Read() no longer initializes Py_GetArgcArgv(): it is now _PyConfig_Write() responsibility. * _PyConfig_Write() result type becomes PyStatus instead of void. * Write an unit test on Py_GetArgcArgv().
* bpo-40854: Allow overriding sys.platlibdir via PYTHONPLATLIBDIR env-var ↵Sandro Mani2020-06-081-0/+26

* bpo-40453: Add PyConfig._isolated_subinterpreter (GH-19820)Victor Stinner2020-05-011-0/+3
| | | | | | | | | An isolated subinterpreter cannot spawn threads, spawn a child process or call os.fork(). * Add private _Py_NewInterpreter(isolated_subinterpreter) function. * Add isolated=True keyword-only parameter to _xxsubinterpreters.create(). * Allow again os.fork() in "non-isolated" subinterpreters.
* bpo-40334: Rename PyConfig.use_peg to _use_peg_parser (GH-19670)Victor Stinner2020-04-231-5/+5
| | | | | | | | | | | * Rename PyConfig.use_peg to _use_peg_parser * Document PyConfig._use_peg_parser and mark it a deprecated * Mark -X oldparser option and PYTHONOLDPARSER env var as deprecated in the documentation. * Add use_old_parser() and skip_if_new_parser() to test.support * Remove sys.flags.use_peg: use_old_parser() uses _testinternalcapi.get_configs() instead. * Enhance test_embed tests * subprocess._args_from_interpreter_flags() copies -X oldparser

| | | | 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 Stinner2020-04-131-2/+2
| | | | | | | | Don't access PyInterpreterState.config member directly anymore, but use new functions: * _PyInterpreterState_GetConfig() * _PyInterpreterState_SetConfig() * _Py_GetConfig()
* bpo-22490: Remove __PYVENV_LAUNCHER__ from environment during launch (GH-9516)Ronald Oussoren2020-03-221-0/+11

| | | | | | | 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-38317: Fix PyConfig.warnoptions priority (GH-16478)Victor Stinner2019-09-291-42/+82
| | | | | | | | | Fix warnings options priority: PyConfig.warnoptions has the highest priority, as stated in the PEP 587. * Document options order in PyConfig.warnoptions documentation. * Make PyWideStringList_INIT macro private: replace "Py" prefix with "_Py". * test_embed: add test_init_warnoptions().
