Message #5 received at submit <at> debbugs.gnu.org (full text, mbox):
file-expand-wildcards permission error on top-level mount point
Evaluating (file-expand-wildcards "/*/SOME-DIR/*")
Where the first kleene's target is a mount point e.g.:
"/mnt/SOME-DIR/*"
Signals this error:
(file-error "Opening directory" "permission denied" "/lost+found/")
I'm not sure where the error is getting signalled whether its happening
under the root mount point e.g. "/" or if its occuring under
"/mnt/God-knows-where/..."
On this sytem "lost+found" is the directory that was placed in an ext4
partition for recovery purposes.
It appears that `file-expand-wildcards' gets trounced via
`directory-files' which is signaling an error if the permissions
aren't kosher somewhere.
Shouldn't one of these guys be checking with `file-readable-p' or
`file-attributes' at some such at some point whilst walking the
filesytem?
The error is signalled here too:
(file-expand-wildcards "/*/etc/*.conf")
Whereas this works fine:
(file-expand-wildcards "/etc/*.conf")
which seems odd because in each case (error or not) the permissions
can't be more than root:root i.e. the file-list returnd by the last
form are all root:root.
Surely one shouldn't need to be considering umask/dmask/setuid
etc. just to use this function?
On a GNU Emacs 23.2.1
