* bpo-36471: Add _Py_RunMain() (GH-12618)Victor Stinner2019-03-291-2/+13
| | | | | * Add config_read_cmdline() subfunction. Remove _PyCmdline structure. * _PyCoreConfig_Read() now also parses config->argv command line arguments
* bpo-36443: Disable C locale coercion and UTF-8 Mode by default (GH-12589)Victor Stinner2019-03-271-4/+1
| | | | | | | | | | | | | | | | | | | | | | | | bpo-36443, bpo-36202: Since Python 3.7.0, calling Py_DecodeLocale() before Py_Initialize() produces mojibake if the LC_CTYPE locale is coerced and/or if the UTF-8 Mode is enabled by the user configuration. This change fix the issue by disabling LC_CTYPE coercion and UTF-8 Mode by default. They must now be enabled explicitly (opt-in) using the new _Py_PreInitialize() API with _PyPreConfig. When embedding Python, set coerce_c_locale and utf8_mode attributes of _PyPreConfig to -1 to enable automatically these parameters depending on the LC_CTYPE locale, environment variables and command line arguments Alternative: Setting Py_UTF8Mode to 1 always explicitly enables the UTF-8 Mode. Changes: * _PyPreConfig_INIT now sets coerce_c_locale and utf8_mode to 0 by default. * _Py_InitializeFromArgs() and _Py_InitializeFromWideArgs() can now be called with config=NULL.
* bpo-36444: Add _PyCoreConfig._init_main (GH-12572)Victor Stinner2019-03-271-0/+1
| | | | | | | | * Add _PyCoreConfig._init_main: if equals to zero, _Py_InitializeFromConfig() doesn't call _Py_InitializeMainInterpreter(). * Add interp_p parameter to _Py_InitializeFromConfig(). * pymain_init() now calls _Py_InitializeFromConfig(). * Make _Py_InitializeCore() private.
* bpo-36444: Remove _PyMainInterpreterConfig (GH-12571)Victor Stinner2019-03-271-29/+0

* bpo-36301: Test Python init with isolated (GH-12569)Victor Stinner2019-03-261-0/+20
| | | Add test_preinit_isolated1() and test_preinit_isolated2() test_embed.
* bpo-36301: Cleanup preconfig.c and coreconfig.c (GH-12563)Victor Stinner2019-03-261-8/+9
| | | | | | | | | | | | | | | * _PyCoreConfig_Write() now updates _PyRuntime.preconfig * Remove _PyPreCmdline_Copy() * _PyPreCmdline_Read() now accepts _PyPreConfig and _PyCoreConfig optional configurations. * Rename _PyPreConfig_ReadFromArgv() to _PyPreConfig_Read(). Simplify the code. * Calling _PyCoreConfig_Read() no longer adds the warning options twice: don't add a warning option if it's already in the list. * Rename _PyCoreConfig_ReadFromArgv() to _PyCoreConfig_Read(). * Rename config_from_cmdline() to _PyCoreConfig_ReadFromArgv(). * Add more assertions on _PyCoreConfig in _PyCoreConfig_Read(). * Move some functions. * Make some config functions private.
* bpo-36301: Remove _PyCoreConfig.preconfig (GH-12546)Victor Stinner2019-03-261-17/+28
| | | | | | * Replace _PyCoreConfig.preconfig with 3 new fields in _PyCoreConfig: isolated, use_environment, dev_mode. * Add _PyPreCmdline.dev_mode. * Add _Py_PreInitializeFromPreConfigInPlace().
* bpo-36301: Add _Py_GetConfigsAsDict() function (GH-12540)Victor Stinner2019-03-251-38/+74
| | | | | | | * Add _Py_GetConfigsAsDict() function to get all configurations as a dict. * dump_config() of _testembed.c now dumps preconfig as a separated key: call _Py_GetConfigsAsDict(). * Make _PyMainInterpreterConfig_AsDict() private.
* bpo-36301: _PyCoreConfig_Read() ensures that argv is not empty (GH-12347)Victor Stinner2019-03-151-1/+1
| | | If argv is empty, add an empty string.
* bpo-36142: PYTHONMALLOC overrides PYTHONDEV (GH-12191)Victor Stinner2019-03-061-2/+8
| | | | | | | | bpo-34247, bpo-36142: The PYTHONMALLOC environment variable has the priority over PYTHONDEV env var and "-X dev" command line option. For example, PYTHONMALLOC=malloc PYTHONDEVMODE=1 sets the memory allocators to "malloc" (and not to "debug"). Add an unit test.
* bpo-36142: Add _PyPreConfig_SetAllocator() (GH-12187)Victor Stinner2019-03-061-3/+2
| | | | | | | | | | | * _PyPreConfig_Write() now reallocates the pre-configuration with the new memory allocator. * It is no longer needed to force the "default raw memory allocator" to clear pre-configuration and core configuration. Simplify the code. * _PyPreConfig_Write() now does nothing if called after Py_Initialize(): no longer check if the allocator is the same. * Remove _PyMem_GetDebugAllocatorsName(): dev mode sets again allocator to "debug".
* bpo-36142: Add _PyMem_GetDebugAllocatorsName() (GH-12185)Victor Stinner2019-03-051-2/+3
| | | | | The development mode now uses the effective name of the debug memory allocator ("pymalloc_debug" or "malloc_debug"). So the name doesn't change after setting the memory allocator.
* bpo-36142: Add _PyPreConfig.allocator (GH-12181)Victor Stinner2019-03-051-23/+29
| | | | | | * Move 'allocator' and 'dev_mode' fields from _PyCoreConfig to _PyPreConfig. * Fix InitConfigTests of test_embed: dev_mode sets allocator to "debug", add a new tests for env vars with dev mode enabled.
* bpo-36142: Remove _PyMain structure (GH-12120)Victor Stinner2019-03-011-0/+5
| | | | | | | | | | | | | * Move fields from _PyMain to _PyCoreConfig: * skip_first_line * run_command * run_module * run_filename * Replace _PyMain.stdin_is_interactive with a new stdin_is_interactive(config) function * Rename _PyMain to _PyArgv. Add "const _PyArgv *args" field to _PyCmdline.
* bpo-35313: Cleanup test_embed.py (GH-10716)Victor Stinner2018-11-261-4/+3
| | | | | * Remove an unused import. * Move get_expected_config() call to check_config() to ease backport to Python 3.7.
* bpo-35313: Fix test_embed when run from venv (GH-10713)Victor Stinner2018-11-261-63/+68
| | | | test_embed.InitConfigTests now gets the expected configuration from a child process run with -S to not run the site module.
* bpo-35239: _PySys_EndInit() copies module_search_path (GH-10532)Victor Stinner2018-11-161-8/+3
| | | | | | | | | | | * The _PySys_EndInit() function now copies the config->module_search_path list, so config is longer modified when sys.path is updated. * config->warnoptions list and config->xoptions dict are also copied * test_embed: InitConfigTests now also tests main_config['module_search_path'] * Fix _Py_InitializeMainInterpreter(): don't use config->warnoptions but sys.warnoptions to decide if the warnings module should be imported at startup.
* bpo-35233: InitConfigTests tests more config vars (GH-10541)Victor Stinner2018-11-141-84/+127
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | test_embed.InitConfigTests tests more configuration variables. Changes: * InitConfigTests tests more core configuration variables: * base_exec_prefix * base_prefix * exec_prefix * home * legacy_windows_fs_encoding * legacy_windows_stdio * module_search_path_env * prefix * "_testembed init_from_config" tests more variables: * argv * warnoptions * xoptions * InitConfigTests: add check_global_config(), check_core_config() and check_main_config() subfunctions to cleanup the code. Move also constants at the class level (ex: COPY_MAIN_CONFIG). * Fix _PyCoreConfig_AsDict(): don't set stdio_encoding twice * Use more macros in _PyCoreConfig_AsDict() and _PyMainInterpreterConfig_AsDict() to reduce code duplication. * Other minor cleanups.
* bpo-35233: Rewrite test_embed.InitConfigTests (GH-10524)Victor Stinner2018-11-131-40/+86
| | | | | | | | | | | | * Fix _PyCoreConfig_SetGlobalConfig(): set also Py_FrozenFlag * Fix _PyCoreConfig_AsDict(): export also xoptions * Add _Py_GetGlobalVariablesAsDict() and _testcapi.get_global_config() * test.pythoninfo: dump also global configuration variables * _testembed now serializes global, core and main configurations using JSON to reuse _Py_GetGlobalVariablesAsDict(), _PyCoreConfig_AsDict() and _PyMainInterpreterConfig_AsDict(), rather than duplicating code. * test_embed.InitConfigTests now test much more configuration variables
* bpo-35233: Fix _PyMainInterpreterConfig_Copy() (GH-10519)Victor Stinner2018-11-131-6/+36
| | | | | | | | * Fix _PyMainInterpreterConfig_Copy(): copy 'install_signal_handlers' attribute * Add _PyMainInterpreterConfig_AsDict() * Add unit tests on the main interpreter configuration to test_embed.InitConfigTests * test.pythoninfo: log also main_config
* Revert "bpo-34589: Add -X coerce_c_locale command line option (GH-9378)" ↵Victor Stinner2018-09-191-2/+6
| | | | | | | | | | | | | | | | (GH-9430) * Revert "bpo-34589: Add -X coerce_c_locale command line option (GH-9378)" This reverts commit dbdee0073cf0b88fe541980ace1f650900f455cc. * Revert "bpo-34589: C locale coercion off by default (GH-9073)" This reverts commit 7a0791b6992d420dc52536257f2f093851ed7215. * Revert "bpo-34589: Make _PyCoreConfig.coerce_c_locale private (GH-9371)" This reverts commit 188ebfa475a6f6aa2d0ea14ca8e1fbe7865b6d27.
* bpo-34589: C locale coercion off by default (GH-9073)Victor Stinner2018-09-171-4/+0
| | | | | | | | | Py_Initialize() and Py_Main() cannot enable the C locale coercion (PEP 538) anymore: it is always disabled. It can now only be enabled by the Python program ("python3). test_embed: get_filesystem_encoding() doesn't have to set PYTHONUTF8 nor PYTHONCOERCECLOCALE, these variables are already set in the parent.
* bpo-34589: Make _PyCoreConfig.coerce_c_locale private (GH-9371)Victor Stinner2018-09-171-2/+2
| | | | | | | | _PyCoreConfig: * Rename coerce_c_locale to _coerce_c_locale * Rename coerce_c_locale_warn to _coerce_c_locale_warn These fields are now private (name prefixed by "_").
* bpo-34579: Fix test_embed DEFAULT_CON AIX (GH-9063)Michael Felt2018-09-151-3/+7
| | | | | | | | | | | | | | | | * Modify DEFAULT_CONFIG for AIX * bedevere/news did not like old name * Modify NEWS entry * Modified per peer review * Define and use NULL_STR constant to account for AIX libc behavior * Modify per peer review * Modify NEWS
* bpo-34523: Py_DecodeLocale() use UTF-8 on Windows (GH-8998)Victor Stinner2018-08-291-20/+19
| | | | | | | Py_DecodeLocale() and Py_EncodeLocale() now use the UTF-8 encoding on Windows if Py_LegacyWindowsFSEncodingFlag is zero. pymain_read_conf() now sets Py_LegacyWindowsFSEncodingFlag in its loop, but restore its value at exit.
* bpo-34523: Add _PyCoreConfig.filesystem_encoding (GH-8963)Victor Stinner2018-08-291-2/+39
| | | | | | | | | | | | | | | | | | | | | | | _PyCoreConfig_Read() is now responsible to choose the filesystem encoding and error handler. Using Py_Main(), the encoding is now chosen even before calling Py_Initialize(). _PyCoreConfig.filesystem_encoding is now the reference, instead of Py_FileSystemDefaultEncoding, for the Python filesystem encoding. Changes: * Add filesystem_encoding and filesystem_errors to _PyCoreConfig * _PyCoreConfig_Read() now reads the locale encoding for the file system encoding. * PyUnicode_EncodeFSDefault() and PyUnicode_DecodeFSDefaultAndSize() now use the interpreter configuration rather than Py_FileSystemDefaultEncoding and Py_FileSystemDefaultEncodeErrors global configuration variables. * Add _Py_SetFileSystemEncoding() and _Py_ClearFileSystemEncoding() private functions to only modify Py_FileSystemDefaultEncoding and Py_FileSystemDefaultEncodeErrors in coreconfig.c. * _Py_CoerceLegacyLocale() now takes an int rather than _PyCoreConfig for the warning.
* bpo-34485: Add _PyCoreConfig.stdio_encoding (GH-8881)Victor Stinner2018-08-291-3/+33
| | | | * Add stdio_encoding and stdio_errors fields to _PyCoreConfig. * Add unit tests on stdio_encoding and stdio_errors.
* bpo-34485: Enhance init_sys_streams() (GH-8978)Victor Stinner2018-08-281-8/+8
| | | | | | | | | | | | | | | Python now gets the locale encoding with C code to initialize the encoding of standard streams like sys.stdout. Moreover, the encoding is now initialized to the Python codec name to get a normalized encoding name and to ensure that the codec is loaded. The change avoids importing _bootlocale and _locale modules at startup by default. When the PYTHONIOENCODING environment variable only contains an encoding, the error handler is now is now set explicitly to "strict". Rename also get_default_standard_stream_error_handler() to get_stdio_errors(). Reduce the buffer to format the "cpXXX" string (Windows locale encoding).
* bpo-34170: _PyCoreConfig_Read() defaults to argc=0 (GH-8595)Victor Stinner2018-08-011-0/+2
| | | Add unit tests for argc and argv of _PyCoreConfig.
* bpo-34170: Rename _PyCoreConfig.unbuffered_stdip (GH-8594)Victor Stinner2018-08-011-5/+5
| | | | * Rename _PyCoreConfig.unbuffered_stdio to buffered_stdio * Rename _PyCoreConfig.debug to parser_debug
* bpo-34170: Add _PyCoreConfig._frozen parameter (GH-8591)Victor Stinner2018-08-011-0/+4
| | | Modify frozenmain.c to use _Py_InitializeFromConfig().
* bpo-34170, test_embed: write Py_Initialize() tests (GH-8484)Victor Stinner2018-07-261-1/+158
|
* bpo-34008: Allow to call Py_Main() after Py_Initialize() (GH-8043)Victor Stinner2018-07-201-0/+8
| | | | | Py_Main() can again be called after Py_Initialize(), as in Python 3.6. The new configuration is ignored, except of _PyMainInterpreterConfig.argv which is used to update sys.argv.
* bpo-33932: Calling Py_Initialize() twice does nothing (GH-7845)Victor Stinner2018-06-221-0/+9
| | | | Calling Py_Initialize() twice does nothing, instead of failing with a fatal error: restore the Python 3.6 behaviour.
* bpo-33358: Fix test_embed.test_pre_initialization_sys_options (GH-6612)Pablo Galindo2018-04-271-1/+1
| | | Fix test_embed.test_pre_initialization_sys_options() when building with --enable-shared
* bpo-33042: Fix pre-initialization sys module configuration (GH-6157)Nick Coghlan2018-03-251-5/+26
| | | | | | | | | - 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
* bpo-20891: Reenable test_embed.test_bpo20891() (GH-5420)Victor Stinner2018-01-291-3/+0
|
* bpo-20891: Skip test_embed.test_bpo20891() (#4967)Victor Stinner2017-12-211-0/+3
| | | | | | Skip the test failing randomly because of known race condition. Skip the test to fix macOS buildbots until a decision is made on the proper fix for the race condition.
* bpo-20891: Fix PyGILState_Ensure() (#4650)Victor Stinner2017-11-301-0/+10
| | | | | | | When PyGILState_Ensure() is called in a non-Python thread before PyEval_InitThreads(), only call PyEval_InitThreads() after calling PyThreadState_New() to fix a crash. Add an unit test in test_embed.
* bpo-32136: Separate embedding tests from C API tests (GH-4567)Nick Coghlan2017-11-271-0/+203
Some parts of the C API are only relevant to larger applications embedding CPython as a runtime engine. The helpers to test those APIs are already separated out into Programs/_testembed.c, this update moves the associated test cases out into their own dedicated test file.
