Trac: TypeError: can't compare datetime.datetime to str
This problem appears when sorting closed tickets by their "modified" field. Example. The source of the problem appears to be that a few old tickets don't have a "modified" time (changetime). Instead their "changetime" field seems to be set to the empty string.
Apparently similar issues have been known to the Trac developers for a while: https://trac.edgewall.org/ticket/12029.
How to Reproduce
While doing a GET operation on /query
, Trac issued an internal error.
(please provide additional details here)
