My issue didn't make this clear, but there were really two problems here:
1) Why did the switch --relocate have no effect?
2) Why was it silent about that fact?
I decided to file an issue about (2) only, because I figured once
Subversion is correctly reporting the reasons for the failure, we can
determine whether (1) was a bug or was expected behavior in this case.
Right now, I have no idea *why* the switch failed. (Perhaps it had
something to do with the fact that when I checked out a working copy
from the NEW repository, I was prompted for auth creds?)
So yes, I think it is appropriate to at least warn if the relocate has
no effect; it may even be appropriate to error, but we should at least
warn. I guess if we do a warning, we can suppress it with -q, which
might be desirable for some uses. What do you think?
By the way, just now I tried a slightly different version of the
command, like so:
$ svn info | grep URL
$ svn switch --relocate http://svn.collab.net/repos \
$ svn info | grep URL
So, this time it worked! Notice that this time I left the
"cvs2svn/trunk" off the end of the URLs. But there's another variable
too: this time I already had auth creds, and I don't know if that made
a difference. (I guess I should have saved the working copy, so I
could retry after clearing my stored auth creds, but I didn't think of
that in time, and it would be difficult to reconstruct it, and I can't
switch back because the OLD repository doesn't respond anymore.)
I've attached this thread to the issue, by the way.
