* bpo-34523: Add _PyCoreConfig.filesystem_encoding (GH-8963)Victor Stinner2018-08-2912-100/+296
| | | | | | | | | | | | | | | | | | | | | | | _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 Stinner2018-08-296-135/+265
| | | | * 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 Stinner2018-08-293-19/+13
| | | | | | | | | | | | | | 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 Stinner2018-08-293-18/+40
| | | | | | | 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.
* Improve commutativity of math.hypot() and math.dist() (GH-8984)Raymond Hettinger2018-08-291-13/+19

* bpo-34485: Add _Py_ClearStandardStreamEncoding() (GH-8982)Victor Stinner2018-08-284-97/+111
| | | | | | | | | | * 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 Stinner2018-08-283-13/+19
| | | | | | | | * _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 Stinner2018-08-288-43/+91
| | | | | | | | | | | | | | | 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 Stinner2018-08-285-52/+105
| | | | | | | | 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 Stinner2018-08-285-11/+35
| | | | | | | | | | * 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-21145: Add cached_property decorator in functools (#6982)Carl Meyer2018-08-284-0/+256
| | | | | | Robust caching of calculated properties is harder than it looks at first glance, so add a solid, well-tested implementation to the standard library.

* bpo-32968: Make modulo and floor division involving Fraction and float ↵Elias Zamaria2018-08-274-12/+13
| | | | | | | consistent with other operations (#5956) Make mixed-type `%` and `//` operations involving `Fraction` and `float` objects behave like all other mixed-type arithmetic operations: first the `Fraction` object is converted to a `float`, then the `float` operation is performed as normal. This fixes some surprising corner cases, like `Fraction('1/3') % inf` giving a NaN. Thanks Elias Zamaria for the patch.

* bpo-34454: fix .fromisoformat() methods crashing on inputs with surrogate ↵Paul Ganssle2018-08-233-10/+84
| | | | | | | | | | | | | | | | | | | | code points (GH-8862) The current C implementations **crash** if the input includes a surrogate Unicode code point, which is not possible to encode in UTF-8. Important notes: 1. It is possible to pass a non-UTF-8 string as a separator to the `.isoformat()` methods. 2. The pure-Python `datetime.fromisoformat()` implementation accepts strings with a surrogate as the separator. In `datetime.fromisoformat()`, in the special case of non-UTF-8 separators, this implementation will take a performance hit by making a copy of the input string and replacing the separator with 'T'.
