annotate news/views.py @ 631:f36d1a168be7

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
For issue 27, disable login dialog button during POST. This seems to prevent multiple logins most of the time. You can still bang on the enter key and sometimes get more through.
