autobuild[sn-devel-144]: intermittent test failure detected

Mon Oct 29 23:54:35 UTC 2018

The autobuild test system (on sn-devel-144) has detected an intermittent failing test in 
the current master tree.

The autobuild log of the failure is available here:

   https://git.samba.org/autobuild.flakey.sn-devel-144/2018-10-30-0054/flakey.log

The failure seems to be in the "samba-nt4" suite, whose build logs are available here:

   https://git.samba.org/autobuild.flakey.sn-devel-144/2018-10-30-0054/samba-nt4.stderr
   https://git.samba.org/autobuild.flakey.sn-devel-144/2018-10-30-0054/samba-nt4.stdout

The top commit at the time of the failure was:

commit b37f8f88eaf26a4d12fe9728e09aed68ddaaf1c0

    python: do not use "is" for string equality

    This is not always going to work, and is not guaranteed to be
    consistent even between minor versions.

    Here is a simple counterexample:

    >>> a = 'hello'
    >>> a is 'hello'
    True
    >>> a is 'hello'.lower()
    False
    >>> a == a.lower()
    True

    Possibly it always works for the empty string, but we cannot rely
    on that.
