REVIEW: https://review.gluster.org/19906 (libglusterfs: fix comparison of a NULL dict with a non-NULL dict) posted (#1) for review on release-4.0 by Xavi Hernandez

Comment 2 Worker Ant 2018-04-24 12:52:31 UTC
COMMIT: https://review.gluster.org/19906 committed in release-4.0 by "Xavi Hernandez" <xhernandez@redhat.com> with a commit message- libglusterfs: fix comparison of a NULL dict with a non-NULL dict

Function are_dicts_equal() had a bug when the first argument was NULL and
the second one wasn't NULL. In this case it incorrectly returned that the
dicts were different when they could be equal.
