Subject: Copies symlinks as files
Download (untitled) / with headers
text/plain 2.6k
I run with "links" => 1 and even "safe-links" => 1, but I still see this from time to time when starting a new mirror. I think what happens is that what should be the symlink gets copied first, but as the actual files. Later when it's updated (rrr-fsck adding it an extra time for no reason?), this error happens. I am attaching the rmirror-state and the donelog in case that's helpful.

I only just noticed that actually the modules/by-author directory doesn't successfully get any of the symlinks; only the PAUSE "base files". I think this is the big/only real show-stopper for using rrr for general CPAN.

Just in case someone else is interested in helping, here is what I think is happening: a/b/XYZ/c.tar.gz is the real file. (for example: authors/id/X/XY/XYZ/foo.tar.gz) d/e/XYZ is a symlink to a/b/XYZ (for example modules/by-authors/id/XYZ) The system ends up copying c.tar.gz into d/e/XYZ/c.tar.gz; so when it later gets around to making the symlink, it can't because the directory is already there.

This: https://github.com/abh/rersyncrecent/commit/0e31fa81c4ed14f7adc51860d964074f3a04375f and the small fix/change in rrr-fsck a couple commits later (stat => lstat) seems to help; if not fix it completely. https://github.com/abh/rersyncrecent/commits/
