org-publish-cache-ctime-of-src tries (but does not always succeed) to deal with symlinks: file-symlink-p returns the target as a string, but if the target is relative to the symlink, that's not going to fly. e.g. if c is a symlink like this
/a/b/c->../d/f then (file-symlink-p "/a/b/c") -> "../d/f" but if the current directory is any place other than /a/b, the target will not be found, the file attributes are going to be nil and the function will blow up. Here is a patch born of about 5 mins of contemplation. It solved my immediate problem but it is certainly wrong. It breaks absolute targets (which I think are handled correctly by the original version). I'm not even sure that it correctly handles *all* relative targets. It also needs to treat the case of a non-existent symlink target (where file-symlink-p returns t). It might be safer also to check if the file attributes are nil and deal with that, instead of blowing up. --8<---------------cut here---------------start------------->8--- diff --git a/lisp/org-publish.el b/lisp/org-publish.el index e944eea..dd192d6 100644 --- a/lisp/org-publish.el +++ b/lisp/org-publish.el @@ -1150,7 +1150,7 @@ Returns value on success, else nil."
