bpo-32777: Fix _Py_set_inheritable async-safety in subprocess (GH-5560) (GH-5563)

2018-02-06T06:51:10+00:00

Fix a rare but potential pre-exec child process deadlock in subprocess on POSIX systems when marking file descriptors inheritable on exec in the child process.  This bug appears to have been introduced in 3.4 with the inheritable file descriptors support.

This also changes Python/fileutils.c `set_inheritable` to use the "slow" two `fcntl` syscall path instead of the "fast" single `ioctl` syscall path when asked to be async signal safe (by way of being asked not to raise exceptions).  `ioctl` is not a POSIX async-signal-safe approved function.

2018-02-02T13:32:19+00:00

[3.6] bpo-32555: Fix locale encodings (#5193)

2018-01-15T22:43:24+00:00

On FreeBSD and Solaris, os.strerror() now always decode the byte
string from the current locale encoding, rather than using
ASCII/surrogateescape in some cases.

Changes:

* Add _Py_DecodeLocaleEx() and _Py_EncodeLocaleEx() which has an
  additional current_locale parameter.
* PyUnicode_DecodeLocale(), PyUnicode_DecodeLocaleAndSize() and
* PyUnicode_EncodeLocale() now always use the current locale
* encoding, instead of using Py_DecodeLocale()/Py_EncodeLocale().
* Document encoding in Py_DecodeLocale() and Py_EncodeLocale()
  documentations.
* Add USE_FORCE_ASCII define to not define
  decode_ascii_surrogateescape() on Android.

[3.6] bpo-31900: Fix localeconv() encoding for LC_NUMERIC (#4174) (#5192)

2018-01-15T22:23:47+00:00

* Add _Py_GetLocaleconvNumeric() function: decode decimal_point and
  thousands_sep fields of localeconv() from the LC_NUMERIC encoding,
  rather than decoding from the LC_CTYPE encoding.
* Modify locale.localeconv() and "n" formatter of str.format() (for
  int, float and complex to use _Py_GetLocaleconvNumeric()
  internally.
