* _Py_CoerceLegacyLocale() restores LC_CTYPE on fail (GH-9044)Victor Stinner2018-09-031-1/+13
| | | | bpo-34544: If _Py_CoerceLegacyLocale() fails to coerce the C locale, restore the LC_CTYPE locale to the its previous value.
* bpo-34408: Prevent a null pointer dereference and resource leakage in ↵Pablo Galindo2018-08-311-6/+10
| | | | | | | `PyInterpreterState_New()` (GH-8767) * A pointer in `PyInterpreterState_New()` could have been `NULL` when being dereferenced. * Memory was leaked in `PyInterpreterState_New()` when taking some error-handling code path.
* bpo-34523: Use _PyCoreConfig instead of globals (GH-9005)Victor Stinner2018-08-303-28/+34
| | | | | Use the core configuration of the interpreter, rather than using global configuration variables. For example, replace Py_QuietFlag with core_config->quiet.
* bpo-34523: Py_FileSystemDefaultEncoding NULL by default (GH-9003)Victor Stinner2018-08-291-18/+6
| | | | | | | | * Py_FileSystemDefaultEncoding and Py_FileSystemDefaultEncodeErrors default value is now NULL: initfsencoding() set them during Python initialization. * Document how Python chooses the filesystem encoding and error handler. * Add an assertion to _PyCoreConfig_Read().
* bpo-34485: Emit C locale coercion warning later (GH-9002)Victor Stinner2018-08-291-8/+7
| | | | PYTHONCOERCELOCALE=warn warning is now emitted later and written into sys.stderr, rather than being written into the C stderr stream.
* bpo-34523: Support surrogatepass in locale codecs (GH-8995)Victor Stinner2018-08-291-25/+87
| | | | | | | | | | | | | | | | | | | | Add support for the "surrogatepass" error handler in PyUnicode_DecodeFSDefault() and PyUnicode_EncodeFSDefault() for the UTF-8 encoding. Changes: * _Py_DecodeUTF8Ex() and _Py_EncodeUTF8Ex() now support the surrogatepass error handler (_Py_ERROR_SURROGATEPASS). * _Py_DecodeLocaleEx() and _Py_EncodeLocaleEx() now use the _Py_error_handler enum instead of "int surrogateescape" to pass the error handler. These functions now return -3 if the error handler is unknown. * Add unit tests on _Py_DecodeLocaleEx() and _Py_EncodeLocaleEx() in test_codecs. * Rename get_error_handler() to _Py_GetErrorHandler() and expose it as a private function. * _freeze_importlib doesn't need config.filesystem_errors="strict" workaround anymore.
* bpo-34523: Py_DecodeLocale() use UTF-8 on Windows (GH-8998)Victor Stinner2018-08-291-4/+12
| | | | | | | 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: Fix config_init_fs_encoding() (GH-8991)Victor Stinner2018-08-291-1/+1
| | | | Call config_init_fs_encoding() if filesystem_errors is not NULL but filesystem_encoding is NULL.
* bpo-34523: Add _PyCoreConfig.filesystem_encoding (GH-8963)Victor Stinner2018-08-293-71/+196
| | | | | | | | | | | | | | | | | | | | | | | _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 Stinner2018-08-292-132/+209
| | | | * Add stdio_encoding and stdio_errors fields to _PyCoreConfig. * Add unit tests on stdio_encoding and stdio_errors.
* bpo-34485, Windows: LC_CTYPE set to user preference (GH-8988)Victor Stinner2018-08-291-4/+6
| | | | | | | | | | | | | | On Windows, the LC_CTYPE is now set to the user preferred locale at startup: _Py_SetLocaleFromEnv(LC_CTYPE) is now called during the Python initialization. Previously, the LC_CTYPE locale was "C" at startup, but changed when calling setlocale(LC_CTYPE, "") or setlocale(LC_ALL, ""). pymain_read_conf() now also calls _Py_SetLocaleFromEnv(LC_CTYPE) to behave as _Py_InitializeCore(). Moreover, it doesn't save/restore the LC_ALL anymore. On Windows, standard streams like sys.stdout now always use surrogateescape error handler by default (ignore the locale).
* bpo-34485: stdout uses surrogateescape on POSIX locale (GH-8986)Victor Stinner2018-08-291-9/+22
| | | | | | | Standard streams like sys.stdout now use the "surrogateescape" error handler, instead of "strict", on the POSIX locale (when the C locale is not coerced and the UTF-8 Mode is disabled). Add tests on sys.stdout.errors with LC_ALL=POSIX.
* bpo-34485: Add _Py_ClearStandardStreamEncoding() (GH-8982)Victor Stinner2018-08-292-96/+104
| | | | | | | | | | * Move Py_SetStandardStreamEncoding() from pylifecycle.c to coreconfig.c * Add _Py_ClearStandardStreamEncoding() private function. * pymain_free() now calls _Py_ClearStandardStreamEncoding(). * Add assertions add the end of _PyCoreConfig_Read() * _PyCoreConfig_Copy(): rename COPY_STR_ATTR() macro to COPY_WSTR_ATTR(). * Fix get_stdio_errors() indentation.
* bpo-34485: Fix _Py_InitializeCore() for C locale coercion (GH-8979)Victor Stinner2018-08-292-12/+16
| | | | | | | | * _Py_InitializeCore() now sets the LC_CTYPE locale to the user preferred locale before checking if the C locale should be coerced or not in _PyCoreConfig_Read(). * Fix pymain_read_conf(): remember if the C locale has been coerced when the configuration should be read again if the encoding has changed.
* bpo-34485: Enhance init_sys_streams() (GH-8978)Victor Stinner2018-08-281-23/+63
| | | | | | | | | | | | | | | 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-34403: On HP-UX, force ASCII for C locale (GH-8969)Victor Stinner2018-08-283-52/+97
| | | | | | | | On HP-UX with C or POSIX locale, sys.getfilesystemencoding() now returns "ascii" instead of "roman8" (when the UTF-8 Mode is disabled and the C locale is not coerced). nl_langinfo(CODESET) announces "roman8" whereas it uses the Latin1 encoding in practice.
* bpo-34527: POSIX locale enables the UTF-8 Mode (GH-8972)Victor Stinner2018-08-282-5/+13
| | | | | | | | | | * The UTF-8 Mode is now also enabled by the "POSIX" locale, not only by the "C" locale. * On FreeBSD, Py_DecodeLocale() and Py_EncodeLocale() now also forces the ASCII encoding if the LC_CTYPE locale is "POSIX", not only if the LC_CTYPE locale is "C". * test_utf8_mode.test_cmd_line() checks also that the command line arguments are decoded from UTF-8 when the the UTF-8 Mode is enabled with POSIX locale or C locale.

* bpo-34170: _PyCoreConfig_Read() don't replace coerce_c_locale (GH-8658)Victor Stinner2018-08-032-17/+17
| | | | 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 Stinner2018-08-0310-67/+75
| | | | 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 Stinner2018-08-012-12/+2
| | | | | | | | 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: Add _Py_InitializeFromConfig() (GH-8454)Victor Stinner2018-07-252-68/+159
| | | | | | | | | | | | | | * If _Py_InitializeCore() is called twice, the second call now copies and apply (partially) the new configuration. * Rename _Py_CommandLineDetails to _PyCmdline * Move more code into pymain_init(). The core configuration created by Py_Main() is new destroyed before running Python to reduce the memory footprint. * _Py_InitializeCore() now returns the created interpreter. _Py_InitializeMainInterpreter() now expects an interpreter. * Remove _Py_InitializeEx_Private(): _freeze_importlib now uses _Py_InitializeFromConfig() * _PyCoreConfig_InitPathConfig() now only computes the path configuration if needed.
* bpo-34170: Add _PyCoreConfig.bytes_warning (GH-8447)Victor Stinner2018-07-251-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add more fields to _PyCoreConfig: * _check_hash_pycs_mode * bytes_warning * debug * inspect * interactive * legacy_windows_fs_encoding * legacy_windows_stdio * optimization_level * quiet * unbuffered_stdio * user_site_directory * verbose * write_bytecode Changes: * Remove pymain_get_global_config() and pymain_set_global_config() which became useless. These functions have been replaced by _PyCoreConfig_GetGlobalConfig() and _PyCoreConfig_SetGlobalConfig(). * sys.flags.dont_write_bytecode value is now restricted to 1 even if -B option is specified multiple times on the command line. * PyThreadState_Clear() now uses the config from the current interpreter rather than using global Py_VerboseFlag
* bpo-34170: Add _PyCoreConfig.isolated (GH-8417)Victor Stinner2018-07-242-43/+33
| | | | | | | | | | | | | | | * _PyCoreConfig: add isolated and site_import attributes * Replace Py_IgnoreEnvironment with config->ignore_environment when reading the current configuration * _PyCoreConfig_Read() now sets ignore_environment, utf8_mode, isolated and site_import from Py_IgnoreEnvironment, Py_UTF8Mode, Py_IsolatedFlag and Py_NoSiteFlag * _Py_InitializeCore() now sets Py_xxx flags from the configuration * pymain_read_conf() now uses _PyCoreConfig_Copy() to save/restore the configuration. * Rename _disable_importlib of _PyCoreConfig to _install_importlib * _PyCoreConfig_SetGlobalConfig() now also set Py_HashRandomizationFlag * Replace !Py_NoSiteFlag with core_config->site_import

| | | | | | | | | | * _PyCoreConfig_Read() no longer directly modifies Py_IsolatedFlag and Py_NoSiteFlag global configuration flags. The function now requires two pointers to integer, so these flags can be set later, to avoid side effets in _PyCoreConfig_Read(). * pathconfig_global_init() now leaves Py_IsolatedFlag and Py_NoSiteFlag unchanged. * Fix pathconfig_global_init(): avoid computing the path configuration twice, use _PyCoreConfig_SetPathConfig().
* bpo-34170: Rework _PyCoreConfig_Read() to avoid side effect (GH-8353)Victor Stinner2018-07-212-28/+311
| | | | | | | | | | | | | | | | | | | | | | | | | Rework _PyCoreConfig_Read() function which *reads* core configuration to not *modify* the path configuration. A new _PyCoreConfig_SetPathConfig() function now recreates the path configuration from the core configuration. This function is now called very late in _Py_InitializeCore(), just before calling initimport(). Changes: * Add _PyCoreConfig.dll_path * Py_SetPath() now fails with a fatal python error on memory allocation failure. * Rename _PyPathConfig_Calculate() to _PyPathConfig_Calculate_impl() * Replace _PyPathConfig_Init() with _PyPathConfig_Calculate(): the function now requires a _PyPathConfig * Add _PyPathConfig_SetGlobal() to set the _Py_path_config global variable. * Add _PyCoreConfig_InitPathConfig(): compute the path configuration * Add _PyCoreConfig_SetPathConfig(): set path configuration from core configuration * Rename wstrlist_append() to _Py_wstrlist_append() * _Py_wstrlist_append() now handles integer overflow.
* bpo-34008: Allow to call Py_Main() after Py_Initialize() (GH-8043)Victor Stinner2018-07-201-3/+20
| | | | | 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.
