subversion broken by libdb changes

[Gerv]

Subversion is broken for me in released Gutsy:

gerv@otter:bin$ svn update
svn: Unable to open an ra_local session to URL
svn: Unable to open repository 'file:///var/svn/bin/trunk'
svn: Berkeley DB error for filesystem '/var/svn/db' while opening environment:

svn: Cannot allocate memory
svn: bdb: unable to allocate memory for mutex; resize mutex region
gerv@otter:bin$

The following Debian bug seems to be it:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=441544

The fix is in upstream libdb-4.4.20-10, but Gutsy ships with -8. I suggest you need to ship a patch...

This is a really bad bug which results in the death of SVN servers! Please mark as URGENT.

If anybody has a fix, please post it here.

WORKAROUND: run `svnadmin recover /path/to/repository`

I also had to fiddle with the permissions after doing this to deal with our group-based permissions over ssh setup.

[Sam (sam-halliday)]

I can't confirm if the offending code was in the BerkeleyDB backend or in svn itself... so please consider this a bug report against both.

I could reproduce the bug using the following recipe:
In Feisty:
svnadmin create --fs-type bdb test-svn
svn co file:///$PWD/test-svn foo-svn
cd foo-svn/
touch foo
svn add foo
svn ci -m 'bar'

In Gutsy then:
$ LANG=C svn co file:///$PWD/test-svn foo-svn
svn: Unable to open an ra_local session to URL
svn: Unable to open repository 'file:///home/daniel/test-svn'
svn: Berkeley DB error for filesystem '/home/daniel/test-svn/db' while opening environment:

svn: Cannot allocate memory
svn: bdb: unable to allocate memory for mutex; resize mutex region
