SVN hangs on commit with select() timeout
Hi.
I've noticed that SVN hangs when I ask it to commit changes to my
repository. If I monitor what it's doing with strace, the last lines
are:
(using the command strace svn commit -m "foo" > ~/llog 2>&1)

Oops! Sorry about that. Noted now.

That's wrong; BDB 4.x versions are _not_ API compatible. There was an
incompatible change going from 4.0 to 4.1 (and possibly 4.1 to 4.2 too,
but not in those parts that affect us). Subversion handles that at the
source level.

Subversion will compile with any 4.0, 4.1 or 4.2 version, but you can't
just swap the BDB shared libraries.

Currently 4.2.52 is the recommended version to use. Since all 4.x versions
are API compatible, I expect it to work with version 0.33.x too. You could
upgrade instead of downgrade if you want to.

Well, no need to {up,down}grade anymore then :-) Never change a working
config?

Erik.

Thanks for letting me know. I didn't know that (I just use whatever
Debian has packaged), but if it doesn't affect file:///, it's probably
not an issue here.

Hm. I can poke around and see if I can debian to downgrade that gracefully.

That fixed it! After running svnadmin recover, committs no longer
hung.
Thanks for your help!

You *do* know there has been a bugfix release 0.33.1? I it would be
applicable only if you ever use a client/server setup though - not for file:///

I think that at the time of release of 0.33, the recommended version for BDB
on Linux was 4.0.14. Only for systems where that version is not available
(MacOS) or causing problems (Win32) using 4.1.25 was acceptable.
Have you tried running 'svnadmin recover /path/to/repository'? It could fix
problems which don't show up immediately on just any use case.
Also, please check that your *.log files in the db/ directory of your
repository are accessible to the user you are running your svn command with.
If that does not work:
- Are you sharing the repository via file:///?
- Is your repository located on an NFS mount?
bye,
Erik.

Hi Joseph,
Could you provide some more detail please?
- What's the output of 'svn --version'?
- Do you use file:/// or another protocol? If server: what version?
- Which OS do you run on?
- Which version of Berkeley DB do you use?
bye,
Erik.
