RE: [BUG] Removal of dead transactions can fail

Jon,

exactly the same occurred to me with subversion 1.4.3 now updated to
subversion 1.4.4.

There are a few transaction which cannot be removed using rmtxns since
the they are a 'Reference to non-existent node ...". The directories
..\db\transactions\651-1.txn exist but only contain an empty props file.

svnadmin recover and verify say that all is fine

Did you try deleting them manually? Did this work or did you experience
any problems? Or is there another workaround?

Thanks
Jan

Hello,

I have hit a problem which seems to have been around a few years:

This morning, I got a call from a user who couldn't commit, getting an
error "couldn't unlock unknown transaction", with a reported transaction
id of 37404-1.

I tried a dead transaction cleanup. All except the troublesome
transaction were removed, but the remaining removal failed with the
error message "svnadmin: Reference to non-existent node '0.0.t37404-1'
in filesystem 'imp/db'". ('imp' is the name of the repository.)

Yikes! Anyway, I ran an 'svnadmin verify', which reported no problems,
so I think it's probably just the transaction that's corrupted. I'd
assume that 'verify' would check that nodes were present where they were
supposed to be. Also, I checked the file that went in to revision 37404
and it's exactly as it should be. Looking at the contents of the
transaction itself, it's pretty clear that it relates to the failed
commit (which is nothing to do with revision 37404; I suspect another
user committed that shortly after the problematic commit failure).

This was reported in December 2004 and issue 2160 was raised as a
result, see http://svn.haxx.se/dev/archive-2004-12/0429.shtml

That issue is marked as resolved, but maybe it isn't really? Does anyone
agree that I should raise this as a new issue?

Also, can I still safely remove the transaction manually from
db/transactions using 'rm -rf'? I'm going to have to anyway, but I would
like some reassurance :-)

I'm using SVN 1.4.3 on Windows 2003, Apache 2.0.55.

regards,
