Public bug reported: glance-manage throws errors under the python3.5 job because it attempts to open and read a file with utf8 characters in it, but devstack has hard set LANG=C.
ERROR glance.db.sqlalchemy.metadata [-] Failed to parse json file /etc/glance/metadefs/compute-trust.json while populating metadata due to: 'ascii' codec can't decode byte 0xc2 in position 90: ordinal not in range(128): UnicodeDecodeError: 'ascii' codec can't decode byte 0xc2 in position 90: ordinal not in range(128) This only happens under python3 because python3 open() will refer to locale.getpreferredencoding() by default if no encoding is explicitly set. Python2 doesn't have this problem because strings and open operate on binary not encoded things. Devstack sets LANG=C at: https://git.openstack.org/cgit/openstack-dev/devstack/tree/stack.sh#n30 Example job run where this happens: http://logs.openstack.org/10/367810/41/check/gate-tempest-dsvm-py35-ubuntu-xenial/89634cf/logs/devstacklog.txt.gz#_2017-06-13_14_25_15_262 One thing that makes this tricky is that open() under python2 doesn't take an encoding while open() under python3 does. Easy enough to handle this in code but maybe we should try and get six to address this? Also worth noting that the infra test nodes should have a locale of C.utf8 or C.UTF-8, but these locales are apparently (not yet) universal. Considering that devstack wants to enforce and ascii locale the simplest option here may just be to remove the utf8 characters from the metadata json files. '®' and '–' are the two characters which can be replaced with '(R)' and '-'. ** Affects: devstack Importance: Undecided Status: New ** Affects: glance Importance: Undecided Status: New ** Also affects: glance Importance: Undecided Status: New -- You received this bug notification because you are a member of Yahoo!
