I've been maintaining a set of spam filter rule files in Subversion for some time. On the client side this has been almost entirely with 1.6.x on CentOS 5.

I've just recently done a major refresh on my PC, switching to the current Debian stable release, with Subversion 1.8.10.

The directory structure I've suddenly found I've been merging incorrectly looks like:

dev/
  file1.cf
  file2.cf
  file3.cf
  ...
prod/
  file1.cf
  file3.cf
  ...

(Note a small number of files were added in dev/, but have not been copied to prod/. IIRC the few files added to SVN in dev/ but not prod/ got added by the merge, then revert'ed, then OS-rm'ed.)

dev/ and prod/ were created at the same time, in r1. Files were created in dev/, then svn cp'ed to prod/.

With the old 1.6 client, I was able to "svn merge ^/dev" in prod/, and it did what I expected; merge all changes to the relevant files (and add the occasional new file) from dev/ to prod/. merginfo is only maintained on the prod/ directory, not individual files.

With 1.8, it's now complaining that dev/ and prod/ have no common ancestor.

What can I do to get unstuck?
