latest update to git-svn blows up for me

No, and that worked for me as well.  Apparently, I might have corrupted my
metadata because I updated git-svn while I was using it.  Is there any way to
reset the metadata without having to re-fetch 15000 revisions?

Yes, and now after seeing 14000 lines scroll by, I tried again:

Anything you want me to try now?  I'm not in a fast net place (at

rm .git/refs/remotes/$GIT_SVN_ID .git/svn/$GIT_SVN_ID/.rev_db
git svn -i $GIT_SVN_ID rebuild

I don't think that updating git-svn while using it is a problem, because
Perl won't (to my knowledge) reread it after it's loaded, and git-svn
does not re-exec itself (it'll fork, however).  Weird... the change
(15941) was a property-only change; however.

SVN::Core is 1.4.2  - not sure what distro that comes from.

Same here..  I'm still waiting for it to fetch and will try to reproduce
it here.

Meanwhile, can you re-run and use Data::Dumper to dump out $fb right
before it dies with "no blob information"? (in
close_file() of SVN::Git::Fetcher).

Also, can you put some trace messages and dump arguments to add_file()
and open_file() in that package, too?

Thanks.

This may be a great moment in time.

We may have reached the point where git is sentient, and passed the 
Turing test without us even realizing.

Please, somebody tell Sarah Connor.

I fear I may have been looking in the wrong place while trying to
diagnose merlyn's problem.  He did mention he was on a flaky connection
and that may have caused the corruption if he had one of those bad
versions.

I still say it was odd that it happened exactly when I did a git-svn
update in the other window. :)

So, maybe I'll just toss this archive.  Oh wait, can I back it up a few dozen
revs and try to roll forward?  That might be interesting.

git-reset --hard HEAD~10
blow away everything you had me blow away last time
make git-svn equal to HEAD
git-svn rebuild
git-svn fetch

Lemme try that.

Nope.  I reset it back 20 revs, and it correctly fast forwarded until
