| | | | | | | | | | | This fixes an inconsistency between the Python and C implementations of the datetime module. The pure python version of the code was not accepting offsets greater than 23:59 but less than 24:00. This is an accidental legacy of the original implementation, which was put in place before tzinfo allowed sub-minute time zone offsets.

* bpo-37811: FreeBSD, OSX: fix poll(2) usage in sockets module (GH-15202)Miss Islington (bot)2019-08-141-0/+11
| | | | | | | | | | | | | | | | | | | FreeBSD implementation of poll(2) restricts the timeout argument to be either zero, or positive, or equal to INFTIM (-1). Unless otherwise overridden, socket timeout defaults to -1. This value is then converted to milliseconds (-1000) and used as argument to the poll syscall. poll returns EINVAL (22), and the connection fails. This bug was discovered during the EINTR handling testing, and the reproduction code can be found in https://bugs.python.org/issue23618 (see connect_eintr.py, attached). On GNU/Linux, the example runs as expected. This change is trivial: If the supplied timeout value is negative, truncate it to -1.

| | | | | | | | | | | | | | | | | (GH-13073) Calling setlocale(LC_CTYPE, "") on a system where GetACP() returns CP_UTF8 results in empty strings in _tzname[]. This causes time.tzname to be an empty string. I have reported the bug to the UCRT team and will follow up, but it will take some time get a fix into production. In the meantime one possible workaround is to temporarily change the locale by calling setlocale(LC_CTYPE, "C") before calling _tzset and restore the current locale after if the GetACP() == CP_UTF8 or CP_UTF7 @zooba https://bugs.python.org/issue36779 (cherry picked from commit b4c7defe58695a6670a8fdeaef67a638bbb47e42) Co-authored-by: Paul Monson <paulmon@users.noreply.github.com>
