Hi all,
imo, it would be better to set up multiple repositories for the externals, abstractions, and the pd core ... maybe ever multiple repositories for the externals ...
Multiple repos for externals, abs and pd core makes sense, but not for each externals or branch of externals, IMO. I think externals should be a repo on its own.
i don't think there is a real reason for multiple repositories. I have been working with split repositories for quite a while because of missing path-wise access control in older svn versions, but this restriction is gone now. I find it inconvenient and unnecessary. SVN has far better capabilities of dealing with directories like cvs, so this would only complicate things. If SF provides the repo there will probably be only a single one available anyway.
best greetings, Thomas
