Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Keep configuration and data in distinct directories This allows having distinct volumes for configuration and data (artifact database, generated mapfiles and shapefiles, etc.). While at it, cleanup MapServer configuration a little bit.
