"Checksum mismatch while reading representation"
Hi folks,
is there any way to recover from "Checksum mismatch while reading representation" within a known revision?
Since a workmate had checked in rev. 763 last Friday we are no more able to checkout/export the affected directory due to the above error.
Unfortunately the crash occured after several other commits since the Thursday backup.
As far as I understand there is a difference between the MD5 digest which svnserve computed during checkin against the digest computed from the stored data while trying to checkout.
Given that, I wondered if it were possible to either 1. "fake" the digest in order to at least be able to checkout rev. 763 and commit the correct contents again or 2. patch the revision file such that it reflects the correct contents (which in turn would yield the stored digest).
svnadmin does not seem to be able to do the trick.
Hope this will not turn out to be an RTFM question :-)
TIA and best regards,
Thomas

Hi everybody,
Firstly, I used "fsfsverify.py" (I am willing to propose medal for the
author..)
to analyse failed revision records.
http://www.szakmeister.net/blog/fsfsverify/
However, I had to enclose line:
(rev, offset, length, size, digest) = value.split(' ')
into "try-except" -structure
try:
(rev, offset, length, size, digest) = value.split(' ')
except:
print value
sys.exit()
because in some files the space delimiter had been replaced with "
-sign. WTF...
Secondly, the "fsfsverify.py" could not locate all errors so I searched
the signaled error message
from "fs_fs.c" in Subversion sources. Then I added printf -clauses into
C-code and recompiled Subversion
in order to actually see the offending line in data. I think Subversion
should be modified to always
print out the offending data with the error messages in "fs_fs.c".
str = apr_strtok(NULL, " ", &last_str);
if (str == NULL)
return svn_error_create(SVN_ERR_FS_CORRUPT, NULL,
_("Malformed text rep offset line in node-rev"));
/* OK, we print the error message, but why not print the contents of
variable &last_str too? /pekka */
I had run "svnadmin verify" with v1.4.3 before dumping the FSFS
repository. When I created Berkeley DB
and tried to import dump with v1.4.5 into it I could not. Then I created
FSFS database and I got
checksum errors in revisions done in year 2005! This in my opinion rules
out network errors.
When analysing MD5s I noticed that different files in the same revision
had identical checksums!
I am running SVN in SUSE 8.x and have compiled it always from the sources.
I compile Apache using arp -libraries distributed with SVN and I am
using prefork MPM.
The database is accessed using SSL and, now that I think of it, before I
compiled v1.4.6
I also updated to the latest OpenSSL library; maybe it is related...

This is one more error message is added now. This I got when I
ran "svnadmin verify" command for the bellow error reported by the client.

Ya I have to reload the carpeted repositories any way. But at least the
problem should not occur after the reload and once the version is upgraded.
Also main error we are getting and corrupting the repository is as pasted
bellow.
#####################################################
svn: REPORT request failed on '/!svn/vcc/default'
svn: REPORT of '/!svn/vcc/default': Could not read response body: Secure
connection truncated
(https://hood.robosoft.co.in)
########################################################
This error is heavily corrupting the repositories. Is there any idea this
is because of the v1.4.5 problem? Or something else?
Thanks

Re: "Checksum mismatch while reading representation"

Dear egoots,
Initially we suspect, may be because of large size file like >500 MB so I
had posted. But yesterday in the night even we faced the same error message
just for the 63 MB file committing to a repository.
I attached the error message.
Please suggest me if really I want to change my version to 1.4.6? Will it
solve my problem? Day by day most of the repositories are giving this
problem...
Please
Thanks
Ashwin Patil

Re: "Checksum mismatch while reading representation"

Hi there,
Even I had updated our SVN server from 1.4.3 to 1.4.5 on NOV
2007. And we are facing lot problem with the repositories. Most of the
repositories are corrupted. Mean while I was upgraded it to SSL connection
[https] with the apache 2.059. I am not sure because of which [SVN OR
APACHE] versions the repositories are getting corrupting. Even the same
error message I had put in the last post but I didnt received any response.
When I tried to commit big size files like >500 MB the connection will
close by the following error and repository get corrupts.
#####################################################
svn: REPORT request failed on '/!svn/vcc/default'
svn: REPORT of '/!svn/vcc/default': Could not read response body: Secure
connection truncated
(https://hood.robosoft.co.in)
########################################################
And when this error is reported by the repository users, I tried with
the "svnadmin varify" command and there it gives the error as bellow.
1. "Checksum mismatch while reading representation"
AND
2. subversion:~ root# /usr/local/bin/svnadmin
verify /Volumes/Projects/Subversion/Projects/Medha
* Verified revision 0.
* Verified revision 1.
* Verified revision 2.
svnadmin: Decompression of svndiff data failed
subversion:~ root#
So now I suspect on subversion 1.4.5 version I had upgraded. Around 20 of
the repositories corrupted. Please can you all give me how I would go
about it now... ? Is really required to upgrade it to 1.4.6 version?

Well if it was in 1.4.5 then it was likely also in 1.4.4 as the only fix
in 1.4.5 was a security fix.
1.4.6 did fix at least one possible repository corruption bug.
For details see:

I suspect v1.4.5 since after upgrading (thru svnadmin dump)
my server from v1.4.3 I started getting a lots of MD5 problems.
After upgrading to v1.4.6 I have had none (knock on wood)

I suspect v1.4.5 since after upgrading (thru svnadmin dump)
my server from v1.4.3 I started getting a lots of MD5 problems.
After upgrading to v1.4.6 I have had none (knock on wood)

After applying the checksum hack, "svnadmin verify" runs through without
any complaints.

What happens when you run "svnadmin verify REPOS_PATH" (server side)?
That should tell you whether the repository revisions are all ok.

Understood.
If you do happen to find out (e.g. hardware issues), it would be good to
hear on the list.

Thanks for the pointer!
In the meantime, I managed to get things running again.
I took the approach to replace the stored MD5 hash by the expected one;
although I can't tell for sure whether the affected file is *really*
consistent now (since it is some strange binary format) I am happy to have
my repository back in a usable state.
But I would be even happier if I had any clue about the reason of the
misbehaviour...
Best regards,
Thomas

The following post (and follow ups in the thread) describe one users
