base checksum mismatch during apply_delta

[Kevin Smith]

We have a subversion repo with about 16000 revisions which appears to work fine both with svn and with an existing bzr-svn branch. I just tried to create a new bzr branch on a new machine (Ubuntu 9.04 Jaunty, using its standard bzr versions), and am getting this error:

bzr: ERROR: base checksum mismatch: 'dfd29a2e55275396552bcf7d083ba632' != '41b36ab118bfc4f0d574041d171c7c93'

This is a showstopper. I can't use bzr on this project until this is resolved. I will have to fall back to plain subversion.

My destination bzr repo (shared but empty) was originally a 1.9-rich-roots, but I also tried with 1.6.1-rich-roots and the result was the same. I can pull up to bzr -r 14579 but attempting to pull 14580 gives this error. There does not appear to be anything unusual about 14580, and I can do svn diff's of that changeset and a couple on either side of it. This leads me to believe it is not a problem with the svn repo being corrupted.

The svn repo in question is not publicly available, but I believe I could provide access to a bzr developer on a limited basis for debugging. I'm a ruby/java programmer so could fiddle with python under supervision, if necessary. This repo has minimal merging, so is mostly trunk with a few release branches. In other words, a simple flow.

As mentioned, I'm using whatever is current in 9.04/Jaunty. Took me a minute to find out how to find out what version of bzr-svn I have. Turns out that is: svn 0.5.3

Having pulled as much as possible into bzr, here is the log:

When I look at svn, it claims that "Put expanded sub-columns to the left instead of to the right" was #15033.

Commits svn#15031 and svn#15032 were simple text modification commits performed by svn. Commits svn#15033 and svn#15034 were simple text modification commits performed by bzr-svn.

[Kevin Smith (ubuntu-qualitycode)]

Changing status back to new since I added the requested information. Don't know if that's the right process or not, but I didn't want the report to get auto-closed due to incompleteness.

[Jelmer Vernooij (jelmer)]

Yeah, that's the appropriate procedure - that way I can see easily which bug reports are waiting for information and which ones I can act on.

Please try again with the 0.6 branch of bzr-svn, I've added more information that should help debugging this problem.

[Reuben Firmin (reubenf)]

Hey Jelmer,

I have the same issue on the funky repository that I opened previous bugs about. I am on bzr-svn 0.6.1 but it doesn't seem to give much additional information.

Thanks

[Jelmer Vernooij (jelmer)]

You need a development snapshot from bzr or 0.6.2, which has just been released.

[Reuben Firmin (reubenf)]

OK. FYI, this was the stacktrace on 0.6.1:

Sorry about that; since I can't reproduce this problem I added an invalid assertion message. Should be fixed in the 0.6 branch now.

[Reuben Firmin (reubenf)]

Thanks, I will check. FYI the svn repo checks out ok using svnadmin verify.

Same thing, unfortunately :(

If you're willing to NDA I can give you a dump of the repository. Let me know what I can do to help you debug otherwise.

[Reuben Firmin (reubenf)]

I hacked on your code a little and added some print statements before the raise:

        if base_checksum is not None and base_checksum != actual_checksum:
            print base_checksum
            print actual_checksum
            print self.editor.revid
            #print self.editor.branch_path
            #print self.editor.revnum

It turns out that self.editor doesn't have either branch_path or revnum. Are there other properties of self.editor that would be useful in filtering this erroneous checkin out?

[Jelmer Vernooij (jelmer)]

Hi Reuben

You need self.editor.revmeta.branch_path, self.editor.revmeta.revnum

That's the change I had intended to make in the 0.6 branch.

Cheers,

Jelmer

[Reuben Firmin (reubenf)]

OK, interesting. I dumped the entire self.editor.revmeta object. It looks like he was using bzr-svn to check into the svn repository. Here's the content...nothing too proprietary:

Thanks, looks like the text parents aren't recorded properly. We could try to use the proper text parents in this case and just warn.

[Reuben Firmin (reubenf)]

This is blocking our migration, which is at this point urgent... any chance you can give me a workaround for the code?

[Reuben Firmin (reubenf)]

Less urgent now. Working around via bzr-git works just fine.

Thanks

[Kevin Smith (ubuntu-qualitycode)]

Running bzr 2.0.0 with bzr-svn 1.0.0, pull now seems to work for me on the repo referenced above, but svn-import fails (I never tried svn-import before). It seems like lp:336467 which is marked fixed really isn't, and this bug which is not marked fixed somehow is fixed?

kevins@vanessa:~/work/miradi/bzr2/imported$ bzr svn-import svn+ssh://subversion.benetech.org/opt/svn/repositories/benetech.org/Miradi
Using repository layout: trunk0
bzr: ERROR: base checksum mismatch: 'dfd29a2e55275396552bcf7d083ba632' != '41b36ab118bfc4f0d574041d171c7c93' in <email address hidden> (trunk:15034)

Since pull works, this bug is no longer a showstopper for me either. Although Reuben and I are in the same organization, he was able to convert his repo to native bzr bug my repo is stuck in svn. So this one remained a showstopper for me after it was no longer a showstopper for him.

[Kevin Smith (ubuntu-qualitycode)]

Sorry. I spoke too soon. While I can pull, I can't branch without hitting the error. Don't I need to have a branch in order to be able to commit back to the svn repo correctly?

kevins@vanessa:~/work/miradi/bzr2/ssh$ bzr branch svn+ssh://subversion.benetech.org/opt/svn/repositories/benetech.org/Miradi/trunk
bzr: ERROR: base checksum mismatch: 'dfd29a2e55275396552bcf7d083ba632' != '41b36ab118bfc4f0d574041d171c7c93' in <email address hidden> (trunk:15034)

This is a showstopper for our project to move to bzr.

[Vitali Sokhin (vitalius)]

I get the similar error with bzr 2.1.0

vitali@lnx-vitali bzr-test]$ bzr branch ../svn-co
bzr: ERROR: checksum mismatch: '41e7f13c8f35b89aa8d9ad0f8319e613' != 'd41d8cd98f00b204e9800998ecf8427e' in trunk:205

Can you please suggest how to solve/work around the issue?

[Jelmer Vernooij (jelmer)]

Vitali, is your repository public ?

[Kevin Smith (ubuntu-qualitycode)]

The svn repository for my project which is experiencing this problem is not publicly accessible, but the code can be shared. So we will deliver a copy to Jelmer for analysis.

[Tres Seaver (tseaver)]

I have an SVN repository which is read-only public, and where
 'bzr svn-import --incremental' triggered this error.

  http://svn.repoze.org/

The offending revision is #8902:

  $ bzr svn-import file:///home/repoze/svn .
  Using repository layout: trunk1
  Upgrade to svn 1.5 or higher for faster retrieving of revision properties.
  bzr: ERROR: checksum mismatch: '515a60d2c63e3811c0a5f63ab85a08b6' != '02d828258de59f7aada1002caeccb6fa' in repoze.bfg/branches/1.2:8902

I am trying to work around the problem now by blowing away the mirrored repo and
re-importing from scratch.

[Tres Seaver (tseaver)]

Re-importing from scratch worked around the problem for me.

Thanks Tres, I can reproduce this. I think I have some ideas on what
might be going wrong, trying to debug now.

[Philip Peitsch (philip-peitsch)]

Hi Jelmer,

Just wondering if there is an ETA on when this issue might be fixed? This is currently blocking me being able to properly flee to bzr from svn :)

Thanks for all the good work you do!

[Philip Peitsch (philip-peitsch)]

Just found out how easy it is to dump the svn revisionprops... would it be at all helpful in resolving this if I was able to give you access to these logs (I might need to anonymize the data a bit but leave the bzr stuff unchanged). This problem has indeed only started happening after using bzr-svn clients to the bzr repo

It's quite neat how you store the revision stuff :)

[Lalo Martins (lalo.martins)]

updated to 1.0.4 from bzr-beta-ppa, this still happens. Then updated to latest tip of lp:bzr-svn and this still happens. :-(
