Partial metadata rebuilding
For highly active subversion repositories, it can be excruciatingly
slow to pull updates one at a time from subversion. One way around
this is to setup another mercurial repo that pulls new commits from
svn periodicly (say every 5 minutes). When you want to update your
repository, you can pull commits from this mercurial repository via
native mercurial protocols, which will be much faster than pulling
directly from svn.
Unfortunately, your metadata will be out of date after doing so.
Highly active repositories also tend to be very large, which means
that it takes a long time to rebuild your metadata from scratch. To
address this, this adds support to do a partial rebuild on the
metadata by processing only revisions that have been added to the
repository after the last revision we processed.
With the rev map 1k revisions (~2 days) behind tip updatemeta is
dramatically faster than rebuild meta:
$ hg --time svn updatemeta
Time: real 0.570 secs (user 0.480+0.000 sys 0.060+0.000)
$ hg --time svn rebuildmeta
Time: real 129.160 secs (user 128.570+0.000 sys 0.320+0.000)
