We have Subversion 1.6.11 with FSFS backend on CentOS 6.3 served via svnserve -d. I had moved us to a new server and somehow screwed up the loading of the dump files (we used Chris Knights svnbackup.pl and svnrestore.pl which basically do svnadmin dump and load). We went a week with a bunch of checksum errors for anyone who had a file from a missing revision in their working directory. They would go to update and the checksum for that file would not exist anywhere on the new server because the revision had not been loaded during the server migration.
I decided to just reload the full dumps to newly created repos and then just do one incremental dump from the problematic repos just to capture any commits from the last week, and I restored it on top of the full dump,
Now I have new repos that are in sync with the old repos abd also have the last week's work.
My question is: If a revision is missing, how does that affect the files modified in the paths from that revision in their younger (more recent/higher numbered) revisions? If someone added a function in revision 50 for test.cpp and the next time that file was modified is in revision 70 and revision 90, and I do a restore that somehow loses revision 50, will test.cpp be missing that function in revisions 70 and 90? I know there is some binary math formula for figuring out the skip delta scenario, but lets pretend I am not smart enough to grasp that, and dumb it down for me please.
