bpo-37834: Normalise handling of reparse points on Windows (GH-15370)

2019-08-21T22:52:42+00:00

bpo-37834: Normalise handling of reparse points on Windows
* ntpath.realpath() and nt.stat() will traverse all supported reparse points (previously was mixed)
* nt.lstat() will let the OS traverse reparse points that are not name surrogates (previously would not traverse any reparse point)
* nt.[l]stat() will only set S_IFLNK for symlinks (previous behaviour)
* nt.readlink() will read destinations for symlinks and junction points only

bpo-1311: os.path.exists('nul') now returns True on Windows
* nt.stat('nul').st_mode is now S_IFCHR (previously was an error)

bpo-37267: Do not check for FILE_TYPE_CHAR in os.dup() on Windows (GH-14051) (GH-14140)

2019-06-17T08:45:26+00:00

On Windows, os.dup() no longer creates an inheritable fd when handling a
character file.

bpo-36842: Implement PEP 578 (GH-12613)

2019-05-23T15:45:22+00:00

Adds sys.audit, sys.addaudithook, io.open_code, and associated C APIs.

bpo-36775: Add _Py_FORCE_UTF8_FS_ENCODING macro (GH-13056)

2019-05-02T15:28:57+00:00

Add _Py_FORCE_UTF8_LOCALE and _Py_FORCE_UTF8_FS_ENCODING macros to
avoid factorize "#if defined(__ANDROID__) || defined(__VXWORKS__)"
and "#if defined(__APPLE__)".

Cleanup also config_init_fs_encoding().

bpo-36352: Avoid hardcoded MAXPATHLEN size in getpath.c (GH-12423)

2019-03-19T01:58:14+00:00

* Use Py_ARRAY_LENGTH() rather than hardcoded MAXPATHLEN in getpath.c.
* Pass string length to functions modifying strings.

bpo-36352: Clarify fileutils.h documentation (GH-12406)

2019-03-18T16:47:26+00:00

The last parameter of _Py_wreadlink(), _Py_wrealpath() and
_Py_wgetcwd() is a length, not a size: number of characters including
the trailing NUL character.

Enhance also documentation of error conditions.

bpo-31904: Add encoding support for VxWorks RTOS (GH-12051)

2019-03-04T09:02:06+00:00

Use UTF-8 as the system encoding on VxWorks.

The main reason are:

1. The locale is frequently misconfigured.
2. Missing some functions to deal with locale in VxWorks C library.

bpo-34523: Fix C locale coercion on FreeBSD CURRENT (GH-10672)

2018-11-23T12:08:26+00:00

bpo-34523, bpo-35290: C locale coercion now resets the Python
internal "force ASCII" mode. This change fix the filesystem encoding
on FreeBSD CURRENT, which has a new "C.UTF-8" locale, when
the UTF-8 mode is disabled.

Add _Py_ResetForceASCII(): _Py_SetLocaleFromEnv() now calls it.

bpo-28604: Fix localeconv() for different LC_MONETARY (GH-10606)

2018-11-20T15:20:16+00:00

locale.localeconv() now sets temporarily the LC_CTYPE locale to the
LC_MONETARY locale if the two locales are different and monetary
strings are non-ASCII. This temporary change affects other threads.

Changes:

* locale.localeconv() can now set LC_CTYPE to LC_MONETARY to decode
  monetary fields.
* Add LocaleInfo.grouping_buffer: copy localeconv() grouping string
  since it can be replaced anytime if a different thread calls
  localeconv().
* _Py_GetLocaleconvNumeric() now requires a "struct lconv *"
  structure, so locale.localeconv() now longer calls localeconv()
  twice. Moreover, the function now requires all arguments to be
  non-NULL.
* Rename STATIC_LOCALE_INFO_INIT to LocaleInfo_STATIC_INIT.
* Move _Py_GetLocaleconvNumeric() definition from fileutils.h
  to pycore_fileutils.h. pycore_fileutils.h now includes locale.h.
* The _locale module is now built with Py_BUILD_CORE defined.
