annotate roundup/cgi/cgitb.py @ 5814:bd6d41f21a5a

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
More extensive EditCSV testing. Uses test object to cover all types defined by database. Also check for an error with a row that's too short. CSV starts with blank line to verify that it recognises header line. Changes password, date, int, link and other fields. Deletes row and verified that it is retired. Make actions.py properly handle emptying of password field.
