This patch adds a new 'find-rev' command to git-svn that lets you easily
translate between SVN revision numbers and git tree-ish.

Looks useful.

Acked-by: Eric Wong <redacted>

But looks quite wasteful.  Why not run "rev-list -v" or
something instead of running cat-file on revision one-by-one?

Didn't know about "rev-list -v", but I just checked and it still has the
limited-size buffer that --pretty=raw has.

"git-svn log" only runs cat-file if it can't find a git-svn-id: line at
the bottom.  (I used log --abbrev-commit --pretty=raw).

Sorry about the premature Ack, I hadn't had my coffee yet at that point
(and now I'm half awake :x)

Adam:

However, since we're not fetching ranges...

You can do $gs->rev_db_get($rev_nr) to easily find a commit given a
revision.  Bonus points if this works independently of the current HEAD
so you can look up revision numbers on different branches.  (git-svn log
should be made to support this, too)
