* bpo-34523: Py_DecodeLocale() use UTF-8 on Windows (GH-8998)Victor Stinner2018-08-291-0/+2
| | | | | | | 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 Stinner2018-08-291-0/+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, Windows: LC_CTYPE set to user preference (GH-8988)Victor Stinner2018-08-291-0/+3
| | | | | | | | | | | | | | 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 Stinner2018-08-291-0/+3
| | | | | | | 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: Enhance init_sys_streams() (GH-8978)Victor Stinner2018-08-282-0/+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-34403: On HP-UX, force ASCII for C locale (GH-8969)Victor Stinner2018-08-281-0/+3
| | | | | | | | 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 Stinner2018-08-282-0/+5
| | | | | | | | | | * 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 Meyer2018-08-281-0/+2
| | | | | | 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-34347: Fix test_utf8_mode.test_cmd_line for AIX (GH-8923)Michael Felt2018-08-271-0/+1
| | | AIX uses ISO-8859-1 encoding for the C locale.
* bpo-32968: Make modulo and floor division involving Fraction and float ↵Elias Zamaria2018-08-272-0/+2
| | | | | | | 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.
* Remove AIX workaround test_subprocess (GH-8939)Michael Felt2018-08-261-0/+1
| | | | An old apparent AIX behavior workaround in test_subprocess's test_undecodable_env is no longer needed.

* bpo-34454: fix .fromisoformat() methods crashing on inputs with surrogate ↵Paul Ganssle2018-08-231-0/+4
| | | | | | | | | | | | | | | | | | | | 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'.

* bpo-34412: Make signal.strsignal() work on HP-UX (GH-8786)Michael Osipov2018-08-231-0/+1
| | | | | | Introduce a configure check for strsignal(3) which defines HAVE_STRSIGNAL for signalmodule.c. Add some common signals on HP-UX. This change applies for Windows and HP-UX.

| | | | | | | | | os.readlink() now accepts path-like and bytes objects on Windows. Previously, support for path-like and bytes objects was only implemented on Unix. This commit also merges Unix and Windows implementations of os.readlink() in one function and adds basic unit tests to increase test coverage of the function.
