On dump/load, change authors?

Hi,

I want to merge one SVN Repos into another one with svnadmin dump/load,
however I'ld need to change the author during this step. The original
author is 'root' and I want to change it my username. I've looked into
the dump format and it is easy to see what to change. However, my dump
file though it only contains 15 revision is about 800MB in size and I
can't open it in an editor (they try to load the complete file -> the
machine only has 256MB).

Are there any scripts or a build-in functoinality available for this?

thanks
- - Markus

I occasionally have to do this as part of importing new dumpfiles into
the ASF subversion repository, and I use a hacked version of
svndumptool to do it.

You can check out svndumptool from:

http://queen.borg.ch:81/svn/repos/trunk/svn/svndumptool

And then apply the attached patch.

I haven't tried to submit it upstream yet because it's kind of lame,
you have to manually hack the 'mapping' dict in svndump/tools.py to
include the usernames you want changed.  Then you just use the copy
command, and the resulting dumpfile will have your changed authors.

Works for me, your milage may vary, some cars not for use with some sets, etc.

You need to use a stream editor like sed, perl, awk...
Or maybe you dump/edit/load version by version to get smaller files.
