AW: svndumpfilter woes

Hi, Ian,

I think that you should try to check / consider two scenarios:

- Repository corruption: Maybe the existing repository contains
  Inconsistent data for some reason. You should try to check
  "svnadmin verify" on the repository, this will find most
  kinds of corruption.

- Hardware failure: The data reading from the harddisk or your
  RAM may be broken, and occasionally flip some bits. This may
  be the case on the existing server, as well as on the
  destination machine.

Best regards

If that's the only reason you want to get rid of the files in your
dump, you may provide the error message and fix this error because SVN
should be able to load even large binaries.

May this get translated to /*.ncb only and therefore doesn't get
applied recursively? Maybe you need something like **/*.ncb.

Mit freundlichen Grüßen,

Hi Thorsten , thanks for the response.
My main concern at the moment is just loading the dump file and the errors are preventing that. It would be good to filter out the binaries, but its not a priority just now.
The error I get is a hash checksum failure, and only on binary files:
     * editing path : MyFile.ncb ...svnadmin: E200014: Checksum mismatch for '/MyFile.ncb':
   expected:  ab27603550fc52585bd6e98c6d7d0b6c
     actual:  f52642a0cc3186a7da837569fcde32a1
A re-dump didn't seem to help much. In fact I split up the dumps by revision in a bid to fix the problem, but then I got a failure earlier in the repository around revision 2xx. In fact whatever dump file I take seems to fail to load at some point due to a binary file checksum mismatch, which is pretty frustrating.
Cheers,
Ian
