svnadmin dump vs hotcopy

Thursday, February 11th, 2010
  • hotcopy makes a direct copy of the repository. It is fast, but it keeps information about the underlying file system etc. The server where the copy is imported needs to be the same version, have the same config etc.
  • dump is version independent. This means that the exported copy can be used by any version of svn.

IMHO: dump is better for backups and long term archiving (outside a repository) [like a tape in a vault].
hotcopy is better suited to make a quick copy to another server when the other server is up and running.

The base information for this post was found in the svn maillist

svn: Checksum mismatch for file expected: md5, actual: othermd5

Monday, February 8th, 2010

What has (most likely) happened is that the .svn/entries file has gotten corrupt somehow; this can happen if a svn client dies halfway in a commit, or for other reasons, but that is not what this post is about.

Recently got the error message “svn: Checksum mismatch for ‘/var/www/magento/app/locale/sv_SE/template/email/sales/.svn/text-base/testfile.svn-base’; expected: ’2b991059e896f837f33875df8070e1ab’, actual: ’71d7d03cf41d65b6c28471dd2e96c2e1′”

A quick fix this issue is to

  • Remove the .svn directory from the sales folder.
  • Move the folder sales to sales_real
  • Update the email folder (this will recreate the sales folder)
  • Move all the files from sales_real to sales
  • Commit sales
  • Delete sales_real

Obligatory disclaimer: This worked for me, it keeps the file history and all should be well.
If the sales folder would have been larger (and or my connection to the svn server slower) perhaps some other solution is preferred; but this was quick and worked.
