annotate gpp/shoutbox/views.py @ 197:2baadae33f2e

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Got autocomplete working for the member search. Updated django and ran into a bug where url tags with comma separated kwargs starting consuming tons of CPU throughput. The work-around is to cut over to using spaces between arguments. This is now allowed to be consistent with other tags. Did some query optimization for the news app.
