But what is partial_dump.dump? Can you show us the exact commands you used to create it? Did you create this by dumping only revisions 7 and 8 from the original repository, as in 'svnadmin dump /path/to/orig_repos -r7:8 > partial_dump.dump'? In that case, it is expected to behave like you described. Or did you create it by dumping the entire repository, and then svndumpfilter-ing out the unneeded stuff, as in 'svnadmin dump /path/to/orig_repos | svndumpfilter exclude /path/to/unneededstuff > partial_dump.dump'? It is the last technique that I was suggesting, and I would expect that to retain all the existing revision numbers (some revisions might become empty revs because of the filtering, but they should still "count"). -- Johan
