git-svn throwing assertion on old svn tracking branch

git-svn throwing assertion on old svn tracking branch

[Nicolas Vilz]

hello guys,

it has been a while, i tried git in conjunction with svn... i got a nice
history, when working with it. This Work is now a year old.

Now I wanted to get on working and got following error message while
fetching from one specific svn tracking branch:

$ git-svn fetch -i svn_master
perl: subversion/libsvn_subr/path.c:343: svn_path_remove_component: 
Assertion `is_canonical(path->data, path->len)' failed.
Aborted

I checked the svn working copy, it is uptodate now (although i had to
search for it, i havent been using this repository for one year...)

the output of gitk --all looks good, too. So i wonder if that error
message above is only an alternative to say "more work? i ask because i
am finished and have nothing else todo.."

It is only happening to this old repository...

Any help is appreciated. If possible, i would like to keep my development
history for this repository.

I almost forgot, i use git version 1.4.4.3.g545b 

Sincerly
Nicolas

I don't recall seeing that error before.

Are you using the command-line client or the perl SVN libraries?  If
you're using the command-line client, you may want to try:
rm -rf .git/svn/svn_master/tree && git-svn rebuild -i svn_master

Does the directory you're tracking the the repository still
exist?  If it disappeared, git-svn could have some issues with it
(regardless of command-line or SVN libraries).

The repository i am tracking does still exist. both, the tree and the
repository are on the same revision-number, so i am a bit clueless.

I tried a fresh fetch of this repository, it worked. so it shouldn't be
a client-server version mismatch..

I also tried 

rm -rf .git/svn/svn_master/tree && git-svn rebuild -i svn_master

this had no effect to git-svn fetch -i svn_master... i get the very same
error message...

I didn't alter there anything, so i think, fetching works, but if
nothing is there to fetch, there is the initial error message...

beneath there is svn, version 1.4.2 (r22196) ... on that repository is
Subversion version 1.1.4 (r13838).

Weird, so you have the SVN:: libraries installed? (dcommit requires it).
Is the repository you're tracking public?  If so, I'd like to have a
look...

unfortunatelly, its not public...

I noticed, it is not the step of committing anything, but the step to
fetch the revisions in the svn tree. I had a workaround last night... I
used the documentation on Advanced Example: Tracking a Reorganized
Repository to reorganize my tree from broken old repository to
reorganized fresh tree that is working... that all because time was
running out this night and i had to work something.

I keep the old one as a souvenier... The problem lies somewhere there in
the old branch. The history is not lost here in any case.

I backuped my repository and pruned my tree as you suggested it... I
connected to that remote repository... and then the assertion came down
on me. Personally i can live with that reorganized repository. If you
are really keen on digging the error down to ground, i could try to
setup something.

Perhaps back were i worked on that repository, git-svn accessed a little
different from now....

If you are still interested in digging, I think about a private solution
for that.

So the repository was reorganized?  That could be it...

Good to know :)

Some things have changed such as allowing access to repositories with
limited read permissions.  I'm not sure how/if that affects you.  If you
have time, can you try going back to revision
30d055aa1e45b4740edc3bfbff77fa5d65e106ff?  Or try bisecting...

Actually, I just hit upon a weird bug in svm (SVN::Mirror) that was
similar to this (line 114 of the same file, 1.4.2dfsg1-2 in Debian).
Can you try taking the trailing slash out of the URL?
(.git/svn/svn_master/info/url).

Thanks.

Actually I can fetch the revisions now again. Maybe that that little
trailing slash did it.
