Hi,

Using both git 1.7.0.4 and 1.5.6.5 I am unable to clone the Subversion respository for Serendipity.

URL: svn://svn.berlios.de/serendipity

It fails consistently on r1341 with:

(1.5.6.5): Svndiff data contains invalid instruction: Invalid diff stream: [tgt] insn 335 starts beyond the target view position at /usr/bin/git-svn line 3856

and

(1.7.0.4): Svndiff data contains invalid instruction: Invalid diff stream: [tgt] insn 335 starts beyond the target view position at /usr/lib/git-core/git-svn line 5047

On, seemingly UTF-8 encoded data. Any ideas / pointers would be appreciated.

Regards, Anand

That message actually comes from the underlying svn diff itself. To me it looks like a problem with the underlying fsfs on the server:

http://www.szakmeister.net/fsfsverify/

hg convert runs into the same problem, btw.

It would be worthwhile to try svnsync and clone the synced repo, but it seems berlios does not support the necessary replay command. Time to talk to them!

Thanks - I was afraid I was doing something incorrect or it might have been some other issue at my end.

I've reached out to the Berlios and Subversion guys, since the page on fsfsverify seems to indicate it is a hard to reproduce problem needing a test case; and this appears to be one.

Cheers, Anand
