Subversion hackery
In preparation from some git experimentation, I just converted one subversion repository with a layout like this:
repo/ repo/example_dragdrop repo/dedup
Into two separate repositories, each named after their respective project, containing a trunk/ folder with all the content. Here is what I did:
svnadmin dump repo > repo.dump
I had previously done a lot of moving crap around inside this repo that svndumpfilter objected to vehemently, so I edited repo.dump, found those revisions (look for lines starting ^Revision-number:) and deleted them.
Then I could use svndumpfilter to pull the separate projects out of the dump:
cat repo.dump | svndumpfilter --drop-empty-revs --renumber-revs include example_dragdrop > example_dragdrop.dump cat repo.dump | svndumpfilter --drop-empty-revs --renumber-revs include dedup > dedup.dump
I then editted these new dump files to change the name of the top folder from dedup/ and example_dragdrop/ respectively, to trunk/. To do this was mostly a global exchange of /^Node-path: example_dragdrop/ to /Node-path: trunk/. Dedup required an additional step as there were additional renames within the repo. This required the updating of lines starting /^Node-copyfrom-path:/.
Once this was done, new repos could be created:
svnadmin create example_dragdrop ; svnadmin load example_dragdrop < example_dragdrop.dump svnadmin create dedup ; svnadmin load dedup < dedup.dump
And that was pretty much it.
