Tool to test two repositories after a dump/load
Hi,
I have 103 repositories that I dumped/loaded to a new server using this
command :
svnadmin dump repo | ssh -C svnadmin load repo
Everything went fine but when I checked the size of everything I have a
difference of near 50Gb missing on the target.
On the source I have a Debian server with :
subversion version : 1.3.2-5
Filesystem : xfs
On the target Redhat with :
subversion version : 1.4.2-2.el5
Filesystem : ext3
For now I checked two repositories only and I have the same number of
revisions and the same number of files which is nice for now.
But I would like to know if there is a tool or something to provided
some more tests on the data to be sure that nothing has been corrupted
like md5 checksums by example.
Do you know any tool, perl module to do that ?
Any other advice is welcome ...
Cheers,

There is a lot of mp3 and flash (I didnt do the site ;) files and I saw a lot of files copied three times in .svn directories...

You will also be missing any "incomplete" transactions and lock files.
(Although neither of these would normally be 50G in size)
I would suspect the 1.3->1.4 repo format changes also, but it would be
interesting to know total repo sizes.
I've gained a couple of GB reloading old 20GB repos, but it really depends
upon the files that were archived.

I don't know of a tool, but the size difference could be normal. The
repository format was changed in Subversion 1.4 to be more efficient.
Your 50GB difference may be the result of this greater efficiency.
