Revision abfef3bbf5f637c86032763632393ce1ffd23ccc authored by Jakob Stoklund Olesen on 17 April 2014, 06:54:05 UTC, committed by Eric Wong on 24 October 2014, 22:55:26 UTC
In a Subversion repository where many feature branches are merged into a trunk, the svn:mergeinfo property can grow very large. This severely slows down git-svn's make_log_entry() because it is checking all mergeinfo entries every time the property changes. In most cases, the additions to svn:mergeinfo since the last commit are pretty small, and there is nothing to gain by checking merges that were already checked for the last commit in the branch. Add a mergeinfo_changes() function which computes the set of interesting changes to svn:mergeinfo since the last commit. Filter out merged branches whose ranges haven't changed, and remove a common prefix of ranges from other merged branches. This speeds up "git svn fetch" by several orders of magnitude on a large repository where thousands of feature branches have been merged.
