Base checksum mismatch
I've been using subversion with no problems for a while then today I tried
to do a checkin and got the following error:
svn: Base checksum mismatch on
'/server/trunk/editor/src/java/web/content/ContentGroupItemChangeAction.java':
expected: 22f7f6d4a87cdf66a2f87731ab4c2fd7
actual: f1129820c0e9ddec640c6c86a547b01c
I guess I have two questions? Has anyone else had this problem (I
searched the archives and the known issues, but nothing seem quite
right)? Also, does anyone have any ideas on how to recover from this?
thanks

Yes... Windows XP Professional with SP 1.

Do you have WinXP SP1 installed ? There has been a TCP/IP stack issue
that plagged pre-SP1 XP.
Bye,

I tried that... I got the same result. I ended up mailing the file to
someone else to check in, deleting my entire tree and rechcking out the
whole thing after upgrading to the latest client version. We'll see if
this happens again, but I couldn't afford to lose anymore time today.

This means that your "pristine" copy of the file (in .svn/text-base/)
doesn't match the checksum recorded for it in .svn/entries.
'svn commit' sends diffs to the server by comparing your modified file
against the pristine copy; the whole reason for this checksum
verification is to make sure you're sending correct diffs to the server.
So, more than likely, you pristine copy has been changed in some way...
perhaps by a runaway shell script command, or something? Either that,
or you have a disk error or bad sector or something.
Whatever the case, I would copy the edited file far away, destroy the
parent directory (rm -rf), then 'svn up' to have the parent directory
come back. Then copy your edited file back in, run 'svn diff' to verify
it all looks good, and commit.

I doubt this is the cause of my issues. I don't have any filtering
software... and the problem is also intermittent. I do many checkins a
day, but have only seen this issue happen twice in the last week.

I don't know if this applies to your situation, but a coworker of mine was
also getting checksum mismatches when he had some sort of Internet filtering
software on his computer. It was actually munging the transmission of files
across the network in some way. Is it possible that anything like that is
happening? Any other network problems?
