Re: subversion load fails with “no such revision”

An FYI to all,

I'm back trying to deal with this migration, and it's still a giant mess.
The consistent problem seem to be that revision numbering is just flat
wrong when files were renamed in a revision. I'm fixing "svnadmin load"
errors one-at-a-time by the following process:

1. Find in the dump file the "add" that's breaking. Note that there is a
Node-copyfrom-rev that refers to a revision that doesn't exist in the
filtered file (and is irrelevant in the pre-filtered file); that is, the
revision number is incorrect. Also note that the svnadmin load error
message refers to a third revision number that has nothing to do with the
problem either -- it's NOT the number in the Node-copyfrom-rev.
2. Find the first previous revisionof that file that was a change. Note the
correct revision number.
3. Return to the add that's breaking and manually change
the revision number to refer to that commit.
4. Wipe the repo and restart. Go back to step 1.

I'm doing the load with svnadmin 1.7.13, but the dump was from svnadmin
1.6.6. Upgrading the latter is not an option, which is why we're moving and
splitting the repo.
