Subject: [PATCH] Skip recorded symlinks in --setperms (RhBug:1900662)
Michal Domonkos 1a9baf
Michal Domonkos 1a9baf
If a package contains a symlink in the buildroot which is declared as a
Michal Domonkos 1a9baf
ghost or config file but is a regular file or directory on the system
Michal Domonkos 1a9baf
where it's installed, a --setperms call will reset its permissions to
Michal Domonkos 1a9baf
those of a symlink (777 on Linux), which almost certainly is not the
Michal Domonkos 1a9baf
correct thing to do.
Michal Domonkos 1a9baf
Michal Domonkos 1a9baf
To fix that, just skip files that were recorded as symlinks.
Michal Domonkos 1a9baf
Michal Domonkos 1a9baf
This is a special case of a general issue in --setperms; since file
Michal Domonkos 1a9baf
permission semantics may change depending on the file type, to stay on
Michal Domonkos 1a9baf
the safe side, any (ghost or config) file whose type changes after
Michal Domonkos 1a9baf
installation should probably be skipped.  However, symlinks are the most
Michal Domonkos 1a9baf
prominent case here, so let's just focus on that now and avoid adding
Michal Domonkos 1a9baf
too much cleverness to a popt alias (this got us into trouble not too
Michal Domonkos 1a9baf
long ago, see commits 38c2f6e and 0d83637).  We may revisit this in the
Michal Domonkos 1a9baf
eventual C implementation.
