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

Sun Jan 13 07:19:06 UTC 2019

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-144/2019-01-13-0819/flakey.log

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

   https://git.samba.org/autobuild.flakey.sn-devel-144/2019-01-13-0819/samba.stderr
   https://git.samba.org/autobuild.flakey.sn-devel-144/2019-01-13-0819/samba.stdout

The top commit at the time of the failure was:

    lib/ldb: Use new PYARG_ES format for parseTuple

    While 'es' format works great for unicode (in python2) and
    str (in python3) The behaviour with str (in python2) is unexpected.
    In python2 the str type is (re-encoded) with the specified encoding.
    In python2 the 'et' type would be a better match, that ensures 'str'
    type is treated like it was with 's' (no reencoding) and unicode is
    encoded with the specified encoding. However in python3 'et' allows
    byte (or bytearray) params to be accepted (with no reencoding), we
    don't want this. This patch adds a new PYARG_STR_UNI format code which
    is a hybrid, in python2 it evaluates to 'et' and in python3 'es' and
    so gives the desired behaviour for each python version.

    Additionally remove the associated known fail.
