* bpo-33812: Corrected astimezone for naive datetimes. (GH-7578) (GH-7601)Miss Islington (bot)2018-06-101-0/+11
| | | | | | | | | | | | | | | | | | | | | A datetime object d is aware if d.tzinfo is not None and d.tzinfo.utcoffset(d) does not return None. If d.tzinfo is None, or if d.tzinfo is not None but d.tzinfo.utcoffset(d) returns None, d is naive. This commit ensures that instances with non-None d.tzinfo, but d.tzinfo.utcoffset(d) returning None are treated as naive. In addition, C acceleration code will raise TypeError if d.tzinfo.utcoffset(d) returns an object with the type other than timedelta. * Updated the documentation. Assume that the term "naive" is defined elsewhere and remove the not entirely correct clarification. Thanks, Tim.

| | | | | | | | | | (GH-6582) Starting with glibc 2.27.9000-xxx, sigaddset() can return EINVAL for some reserved signal numbers between 1 and NSIG.

| | | | | | | | | | | | | bpo-32844: subprocess: Fix a potential misredirection of a low fd to stderr. When redirecting, subprocess attempts to achieve the following state: each fd to be redirected to is less than or equal to the fd it is redirected from, which is necessary because redirection occurs in the ascending order of destination descriptors. It fails to do so in a couple of corner cases, for example, if 1 is redirected to 2 and 0 is closed in the parent.

* [3.6] bpo-33021: Release the GIL during fstat() calls (GH-6019) (GH-6160)Miss Islington (bot)2018-03-201-2/+9
| | | | | | | | | | | | | | | | fstat may block for long time if the file descriptor is on a non-responsive NFS server, hanging all threads. Most fstat() calls are handled by _Py_fstat(), releasing the GIL internally, but but _Py_fstat_noraise() does not release the GIL, and most calls release the GIL explicitly around it. This patch fixes last 2 calls to _Py_fstat_no_raise(), avoiding hangs when calling: - mmap.mmap() - os.urandom() - random.seed() (cherry picked from commit 4484f9dca9149da135bbae035f10a50d20d1cbbb) Co-authored-by: Nir Soffer <nirsof@gmail.com>
