git-svn: fix several small bugs, enable branch optimization
Share the repack counter between branches when doing multi-fetch. Pass the -d flag to git repack by default. That's the main reason we will want automatic pack generation, to save space and improve disk cache performance. I won't add -a by default since it can generate extremely large packs that make RAM-starved systems unhappy. We no longer generate the .git/svn/$GIT_SVN_ID/info/uuid file, either. It was never read in the first place. Check for and create .rev_db if we need to during fetch (in case somebody manually blew away their .rev_db and wanted to start over. Mainly makes debugging easier). Croak with $? instead of $! if there's an error closing pipes Quiet down some of the chatter, too. Signed-off-by: Eric Wong <normalperson@yhbt.net>
