I cannot speak authoritatively on this topic as we make decisions as a community, but I do not believe there has ever been any intent or consideration to drop the version 2 format. Version 3 is not a superior format, it is just a different format. Specifically, it just stores deltas instead of full texts so the dump file is a lot smaller. I do not believe we would ever consider dropping support for full text dumps or loads, especially at this stage in the project's lifecycle. As for svnrdump and version 3, as someone mentioned this was more an artifact of how it was created. It uses the same ra interface that was created for svnsync and that ships deltas. I do not think it would be very possible to create a version 2 dumpfile out of what is coming over the wire when this runs but I guess that is for someone else to figure out. Most likely it would require creating new ra interfaces which would mean you would need new versions of server and client to use them etc. None of that sounds realistic to me at this point. I can only suggest a hacky workaround. My assumption is that svnrdump is being used because there is no direct access to the svn server and so getting the content over the network is the only way to get access to it. The tldr; would be to create and load a local repository and then do a full dump from that. But here it is in steps: 1. I would always prefer svnsync over svnrdump when possible just because if it gets interupted, svnsync can be restarted easily. 2. svnsync will be creating a local repository, not a dump file. That is going to be handy for the next suggestion. If svnrdump was used, then I would create a repos and load the dump file. 3. Now that a local repository exists, a full dump can be created from that repository Mark
