bulk update of attributes

[we...@tigris.org]

Hi

I need to bulk update some attributes (svn:author and svn:externals) for all versions within a number of repositories. I am currently considering dumping the repositories and working (via scripts) on the subsequent files. This would involve updating the values and associated 'V' counts. Once happy reloading on the new server. Does this sound sensible? Any pitfalls to be aware of (i.e. encoded data, check sums, etc)?

Thanks
Mark

Just to be sure we're clear, svn:author is a revision (unversioned)  
property, while svn:externals is a versioned property.

I recommend not reinventing the wheel when it comes to editing  
dumpfiles. Though their format is not too difficult to understand,  
why risk parsing something incorrectly and not realizing it until  
after it destroyed all your repository history? Just use one of the  
existing tools for this job. It sounds like svndumptool may do what  
you need. I have used it before to make batch changes to  
svn:externals and svn:author when I was migrating a project to Google  
Code.
