Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Eliminate database close method by using weakrefs. . We now use weakrefs in the Classes to keep the database reference, so the close() method on the database is no longer needed. I bumped the minimum python requirement up to 2.1 accordingly. . [SF#487480] roundup-server . [SF#487476] INSTALL.txt I also cleaned up the change message / post-edit stuff in the cgi client. There's now a clearly marked "TODO: append the change note" where I believe the change note should be added there. The "changes" list will obviously have to be modified to be a dict of the changes, or somesuch. More testing needed.

873 # the database when the commit() method is called. Only the anydbm
874 # backend is modified in this way - neither of the bsddb backends have been.
875 # The mail, admin and cgi interfaces all use commit (except the admin tool
876 # doesn't have a commit command, so interactive users can't commit...)
