"No such representation" error
Hello,
all of sudden, I started getting the above error on one my repository.
I wonder:
1. What does it mean (the error is pretty obscure)
2. How could it happen
3. How do I recover
Details.
svn is "svn, version 1.0.9 (r11378)", Berkeley DB is 4.2.52, and repository
is local (no http/svnserver access at all).
I first noticed the problem when doing:
$svn -F ../svn-commit.tmp import .
file:///home/ghost/local/Repositories/svn_personal/papers/thesis
Adding path_enumeration_op1.svg
Adding (bin) thethis.pdf
svn: No such representation '5j'
After that I've tried 'ls' on the repository, which failed with a similar
error.
I've looked at several previous backups, and all of the give error when
doing "svn ls". Backup of rev 21 works OK, backup of rev 23 does not work.
HEAD (rev 24) does not work. (Backup of rev 22 is missing). I don't think I
had any errors on previous commits.
I was using "cp -r" to make backup, but since this is local repository, it
should not matter.
Any ideas?

Adding "Internal error" might be good, yes.

Thanks, but we think we know what the problem is, and are working on how to
fix it.

Maybe, the error message could be more informative. I guess "svn recover"
won't help, but the error might say this is "internal error" which should be
reported on the mailing list.

Thanks, but I found on-disk copies of last two damaged revisions, so recovery
is not important for me now. However, If sending a copy might help to
discover the bug, just say a word.

I've looked at my script and found that it already uses "hotcopy".
Thanks,

Repository corruption.

We recently, with Sleepycat's help, located an obscure bug with subversion's
use of BDB. That might account for it.

Send me an URL to download a copy of the repository.

Dangerous. You should still use "svnadmin hotcopy". Or take steps to ensure
exclusive access the repository during the copy.
