Repository destoryed at random on OS X using new DB, etc.
This is really frustrating... my respository has died *twice* now in
as many months on OS X. I have no idea how to repair it -- I tried
'svnadmin recover' and that seems to have made things worse (!).
First some version numbers. OS X 10.3.3, svn 1.0.1, Berkley DB 4.2.52.
I know there are OS X issues with earlier versions of the DB, but the
docs say this one should be OK. The respository is on my local
filesystem and is for my own use on a personal programming project.
Here's the basic message I got when I tried to commit:
[ian@cobalt ~/Sites/molprobity3]% svn ci
svn: Commit failed (details follow):
svn: Berkeley DB error while checkpointing after Berkeley DB
transaction for filesystem /Users/ian/Sites/svnrepos/db:
Invalid argument
svn: Your commit message was left in a temporary file:
svn: '/Users/ian/Sites/molprobity3/svn-commit.tmp'
The same thing happens when I try updating:
[ian@cobalt ~/Sites/molprobity3]% svn up
svn: Berkeley DB error while checkpointing after Berkeley DB
transaction for filesystem /Users/ian/Sites/svnrepos/db:
Invalid argument
After 'svnadmin recover', things get worse and this new error message persists:
[ian@cobalt ~/Sites]% svnadmin recover svnrepos/
Please wait; recovering the repository may take some time...
svn: DB_RUNRECOVERY: Fatal error, run database recovery
Further recover attempts produce the same result. My only thoughts on
why this is happening are (1) there are some symlinks inside the
project directory (those these are ignored and not versioned) and (2)
there are some files that I don't have permissions to access inside
the project (again, ignored and not versioned). Sometimes I've gone
for months at a time using svn without any problems... Then this
happens without warning.
Somebody, please help! How do I fix this, and how can I keep it from
happening again??
Much thanks,
Ian

No, it looks like I started with svn 0.34 and later upgraded to 1.0.1.
It's failed twice, but both long after I upgraded to 1.0.1. Doing a
dump/load cycle fixed it (temporarily, at least) both times. I can't
be absolutely sure that this is true, but I think it is, b/c this was
the first project I ever tried using svn on and I have both 0.34 and
1.0.1 in /usr/local. I think I used the same version of BDB for both,
though -- I only remember compiling it once...

Ian: did you upgrade your svn or BDB at any point since you started
using this repository? Or has all the software remained constant from
the very beginning?

Hi Max, thanks for all the help and advice. I'll be suitably careful
in following it. However, my repository has died in this way twice
now, and neither time was there anything odd about the check-in
attempt except that it failed. No power failures, hung processes, file
system defects, nada. Now it's true that my Powerbook does hang
sometimes when it goes to sleep and I have to remove the battery (!)
to convince it to shut off and reboot, and these episodes have
happened in the time since my last check-in to this repository.
However, the repository wasn't being accessed anytime around the
failure, and there hasn't been any damage to other parts of the
system, so that seems unlikely to me.
Good luck!

My initial analysis suggests that a write to the database logs is somehow
'getting lost', leaving the databases updated to a later version than there
are log records. BDB then reports this as "Invalid argument".
So, our question to you is:
Did anything unusual of any kind happen around the time the repos became
broken? Power failure? Unclean reboot? Svn process hung?
It is possible that nothing odd happened - there might be a bug in BDB.
Max.

Yes, R40 is (as far as I know) the latest revision. I think I was
trying to commit 41 when everything died.

Thankyou!
What is the youngest revision that should be present in this repository? Is
it r40?
Max.

OK, here's my repository as captured by 'tar czf', weighing in at about 20Mb:
http://kinemage.biochem.duke.edu/~iwd/mp3svnrepos.040727.tgz
Have at it ;) All I ask is that you would let me know if you can
figure out what went wrong. In the meantime, I think I'll switch to
FSFS. I never liked having to build and use Berkley DB anyway --
thanks to the developers for this nice new feature!
Cheers,
Ian
PS Sorry Ben, meant to send this to the list too the first time. Jeez,
I can't even use email right... maybe the svn bug was a user
malfunction ;)

On any web or ftp site, then send the URL in an email to this list.

Yes. FSFS will be in the 1.1.0 release.

Sure, I can post a tarball. Where do I post it, and how?

This looks like another case of issue 1968. Can you post a tarball of
your repository for us to inspect? Pretty please? We'd like to figure
out what's going on.

Have you tried dumping the repository ?
$ svadmin dump svnrepos/
Once you have a dump, your data'll be safe and you can try using the
FSFS backend in 1.1.0.
Hope that helps,
François
