Decompression of svndiff data failed

[vy...@oksystem.cz]

Hello.


I use svn co to checkout my repo. All worked fine for a while, but today I get error



Decompression of svndiff data failed: no size



every time I try to do svn co.


I found out that I got these errors not only from svn co, but also from svnsync, svnadmin dump, etc.


This happened after we commited a new version of file in the repo, all operations fail only if they access that subfolder on that commit revision. If I try to access other files, all work fine.


I found "Decompression of svndiff data failed" message only in one file in sources - /libsvn_delta/svndiff.c - in the zlib_decode function. So, probably data in the repository in the file for this revision somehow corrupted during or after commit? Am I right or there's another reason of these errors (I googled, but what I found is not my case)?


And the most important thing. How can I make my repo consistent back now? I can't even make svnadmin dump and erase that revision from dump file...



Thanks,

Petr Vystyd

What versions of Subversion are you running on your server and the clients?

svndiff is used both in the backend (for storing revisions of files as
binary deltas against previous revisions) and on the wire (if both
client and server ≥1.4, for transmitting the delta from what the client
has (or from the empty file) to the request revision's contents).
