* bpo-36763: Add _PyInitError functions (GH-13395)Victor Stinner2019-05-171-26/+26
| | | | | | | | | | | | | | | * Add _PyInitError functions: * _PyInitError_Ok() * _PyInitError_Error() * _PyInitError_NoMemory() * _PyInitError_Exit() * _PyInitError_IsError() * _PyInitError_IsExit() * _PyInitError_Failed() * frozenmain.c and _testembed.c now use functions rather than macros. * Move _Py_INIT_xxx() macros to the internal API. * Move _PyWstrList_INIT macro to the internal API.
* bpo-36945: Add _PyPreConfig.configure_locale (GH-13368)Victor Stinner2019-05-171-0/+28
| | | | | _PyPreConfig_InitIsolatedConfig() sets configure_locale to 0 to prevent Python to modify the LC_CTYPE locale. In that case, coerce_c_locale an coerce_c_locale_warn are set to 0 as well.
* bpo-36763: Add _PyCoreConfig_InitPythonConfig() (GH-13388)Victor Stinner2019-05-171-28/+123
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* bpo-36763: Add PyMemAllocatorName (GH-13387)Victor Stinner2019-05-171-1/+1
| | | | | | | | | | | | | | * Add PyMemAllocatorName enum * _PyPreConfig.allocator type becomes PyMemAllocatorName, instead of char* * Remove _PyPreConfig_Clear() * Add _PyMem_GetAllocatorName() * Rename _PyMem_GetAllocatorsName() to _PyMem_GetCurrentAllocatorName() * Remove _PyPreConfig_SetAllocator(): just call _PyMem_SetupAllocators() directly, we don't have do reallocate the configuration with the new allocator anymore! * _PyPreConfig_Write() parameter becomes const, as it should be in the first place!
* bpo-36763: Remove _PyCoreConfig.program (GH-13373)Victor Stinner2019-05-171-3/+0
| | | Use _PyCoreConfig.program_name instead.
* bpo-36763: Add _PyCoreConfig.configure_c_stdio (GH-13363)Victor Stinner2019-05-161-0/+7
| | | Add tests for configure_c_stdio and pathconfig_warnings parameters.
* bpo-36763: Add _Py_InitializeMain() (GH-13362)Victor Stinner2019-05-161-12/+50
| | | | | | | | | * Add a private _Py_InitializeMain() function. * Add again _PyCoreConfig._init_main. * _Py_InitializeFromConfig() now uses _init_main to decide if _Py_InitializeMainInterpreter() should be called. * _PyCoreConfig: rename _frozen to pathconfig_warnings, its value is now the opposite of Py_FrozenFlag. * Add an unit test for _init_main=0 and _Py_InitializeMain().
* bpo-36763: Add _PyCoreConfig.parse_argv (GH-13361)Victor Stinner2019-05-161-0/+32
| | | | | | | * _PyCoreConfig_Read() doesn't parse nor update argv if parse_argv is 0. * Move path configuration fields in _PyCoreConfig. * Add an unit test for parse_argv=0. * Remove unused "done": label in _Py_RunMain().
* bpo-36763: InitConfigTests tests all core config (GH-13331)Victor Stinner2019-05-151-0/+22
| | | | | | | | | Remove UNTESTED_CORE_CONFIG from test_embed.InitConfigTests: all core config fields are now tested! Changes: * Test also dll_path on Windows * Add run_main_config unit test: test config using _Py_RunMain().
* bpo-36763: Add test for _PyCoreConfig_SetString() (GH-13275)Victor Stinner2019-05-141-0/+48
| | | | test_embed: add test_init_read_set() to test newly added APIs: test module_search_paths and executable.
* bpo-36763: Remove _PyCoreConfig._init_main (GH-13066)Victor Stinner2019-05-021-5/+0
|
* bpo-36775: _PyCoreConfig only uses wchar_t* (GH-13062)Victor Stinner2019-05-021-2/+2
| | | | | | | | | | | | | | | | | _PyCoreConfig: Change filesystem_encoding, filesystem_errors, stdio_encoding and stdio_errors fields type from char* to wchar_t*. Changes: * PyInterpreterState: replace fscodec_initialized (int) with fs_codec structure. * Add get_error_handler_wide() and unicode_encode_utf8() helper functions. * Add error_handler parameter to unicode_encode_locale() and unicode_decode_locale(). * Remove _PyCoreConfig_SetString(). * Rename _PyCoreConfig_SetWideString() to _PyCoreConfig_SetString(). * Rename _PyCoreConfig_SetWideStringFromString() to _PyCoreConfig_DecodeLocale().
* bpo-36763: Make _PyCoreConfig.check_hash_pycs_mode public (GH-13052)Victor Stinner2019-05-011-1/+1
| | | | | _PyCoreConfig: Rename _check_hash_pycs_mode field to check_hash_pycs_mode (make it public) and change its type from "const char*" to "wchar_t*".
* bpo-36635: Add _testinternalcapi module (GH-12841)Victor Stinner2019-04-181-33/+4
| | | | | | Add a new _testinternalcapi module to test the internal C API. Move _Py_GetConfigsAsDict() function to the internal C API: _testembed now uses _testinternalcapi to access the function.
* bpo-36471: Add _Py_RunMain() (GH-12618)Victor Stinner2019-03-291-2/+25
| | | | | * 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 Stinner2019-03-271-21/+0
| | | | | | | | | | | | | | | | | | | | | | | | 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: Rework _Py_InitializeFromConfig() API (GH-12576)Victor Stinner2019-03-271-9/+9
|
* bpo-36444: Add _PyCoreConfig._init_main (GH-12572)Victor Stinner2019-03-271-5/+5
| | | | | | | | * 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-36301: Test Python init with isolated (GH-12569)Victor Stinner2019-03-271-0/+70
| | | Add test_preinit_isolated1() and test_preinit_isolated2() test_embed.
* bpo-36301: Cleanup preconfig.c and coreconfig.c (GH-12563)Victor Stinner2019-03-261-2/+1
| | | | | | | | | | | | | | | * _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 Stinner2019-03-261-14/+33
| | | | | | * 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 Stinner2019-03-251-45/+10
| | | | | | | * 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: Add _PyWstrList structure (GH-12343)Victor Stinner2019-03-151-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace messy _Py_wstrlist_xxx() functions with a new clean _PyWstrList structure and new _PyWstrList_xxx() functions. Changes: * Add _PyCoreConfig.use_module_search_paths to decide if _PyCoreConfig.module_search_paths should be computed or not, to support empty search path list. * _PyWstrList_Clear() sets length to 0 and items to NULL, whereas _Py_wstrlist_clear() only freed memory. * _PyWstrList_Append() returns an int, whereas _Py_wstrlist_append() returned _PyInitError. * _PyWstrList uses Py_ssize_t for the length, instead of int. * Replace (int, wchar_t**) with _PyWstrList in: * _PyPreConfig * _PyCoreConfig * _PyPreCmdline * _PyCmdline * Replace "int orig_argv; wchar_t **orig_argv;" with "_PyWstrList orig_argv". * _PyCmdline and _PyPreCmdline now also copy wchar_argv. * Rename _PyArgv_Decode() to _PyArgv_AsWstrList(). * PySys_SetArgvEx() now pass the fixed (argc, argv) to _PyPathConfig_ComputeArgv0() (don't pass negative argc or NULL argv). * _PyOS_GetOpt() uses Py_ssize_t
* bpo-36142: PYTHONMALLOC overrides PYTHONDEV (GH-12191)Victor Stinner2019-03-061-7/+21
| | | | | | | | 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 _PyMem_GetDebugAllocatorsName() (GH-12185)Victor Stinner2019-03-051-0/+6
| | | | | 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 Stinner2019-03-051-4/+25
| | | | | | * 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: Add _PyPreConfig.utf8_mode (GH-12174)Victor Stinner2019-03-051-3/+3
| | | | | | | | | | | | * Move following fields from _PyCoreConfig to _PyPreConfig: * coerce_c_locale * coerce_c_locale_warn * legacy_windows_stdio * utf8_mode * _PyPreConfig_ReadFromArgv() is now responsible to choose the filesystem encoding * _PyPreConfig_Write() now sets the LC_CTYPE locale
* bpo-36142: Add _PyPreConfig structure (GH-12172)Victor Stinner2019-03-051-3/+3
| | | | | | * Add _PyPreConfig structure * Move 'ignored' and 'use_environment' fields from _PyCoreConfig to _PyPreConfig * Add a new "_PyPreConfig preconfig;" field to _PyCoreConfig
* bpo-36142: Rework error reporting in pymain_main() (GH-12113)Victor Stinner2019-03-011-3/+3
| | | | | | | | | | | Add a new _Py_INIT_EXIT() macro to be able to exit Python with an exitcode using _PyInitError API. Rewrite function calls by pymain_main() to use _PyInitError. Changes: * Remove _PyMain.err and _PyMain.status field * Add _Py_INIT_EXIT() macro and _PyInitError.exitcode field. * Rename _Py_FatalInitError() to _Py_ExitInitError().
* bpo-35886: Make PyInterpreterState an opaque type in the public API. (GH-11731)Eric Snow2019-02-231-2/+2
| | | Move PyInterpreterState into the "internal" header files.
* bpo-35233: InitConfigTests tests more config vars (GH-10541)Victor Stinner2018-11-141-3/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Stinner2018-11-141-121/+56
| | | | | | | | | | | | * 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 Stinner2018-11-131-41/+80
| | | | | | | | * 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 Stinner2018-09-191-3/+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/+1
| | | | | | | | | 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 Stinner2018-09-171-5/+5
| | | | | | | | _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-34523: Add _PyCoreConfig.filesystem_encoding (GH-8963)Victor Stinner2018-08-291-0/+2
| | | | | | | | | | | | | | | | | | | | | | | _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 Stinner2018-08-291-0/+8
| | | | * 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 Stinner2018-08-281-2/+2
| | | | | | | | | | | | | | | 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() don't replace coerce_c_locale (GH-8658)Victor Stinner2018-08-031-0/+2
| | | | If coerce_c_locale is already set (>= 0), use its value: don't override it.
* bpo-34301: Add _PyInterpreterState_Get() helper function (GH-8592)Victor Stinner2018-08-031-1/+1
| | | | sys_setcheckinterval() now uses a local variable to parse arguments, before writing into interp->check_interval.
* bpo-31650: Remove _Py_CheckHashBasedPycsMode global config var (GH-8608)Victor Stinner2018-08-011-2/+0
| | | | | | | | bpo-31650, bpo-34170: Replace _Py_CheckHashBasedPycsMode with _PyCoreConfig._check_hash_pycs_mode. Modify PyInit__imp() and zipimport to get the parameter from the current interpreter core configuration. Remove Include/internal/import.h file.
* bpo-34170: _PyCoreConfig_Read() defaults to argc=0 (GH-8595)Victor Stinner2018-08-011-1/+11
| | | Add unit tests for argc and argv of _PyCoreConfig.
* bpo-34170: Rename _PyCoreConfig.unbuffered_stdip (GH-8594)Victor Stinner2018-08-011-4/+4
| | | | * 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/+6
| | | Modify frozenmain.c to use _Py_InitializeFromConfig().
* bpo-34170, test_embed: write Py_Initialize() tests (GH-8484)Victor Stinner2018-07-261-0/+331
|
* bpo-34008: Allow to call Py_Main() after Py_Initialize() (GH-8043)Victor Stinner2018-07-201-0/+16
| | | | | 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/+14
| | | | Calling Py_Initialize() twice does nothing, instead of failing with a fatal error: restore the Python 3.6 behaviour.
* bpo-33182: Fix pointer types in _testembed (GH-6310)Nick Coghlan2018-03-301-5/+7
|
* bpo-33042: Fix pre-initialization sys module configuration (GH-6157)Nick Coghlan2018-03-251-2/+70
| | | | | | | | | - 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
