Re: Strange behavior from unlink() Unix-type API

Anyway, I believe Eric is misreading the documentation at the link he supplied. There is definitely no need to have permissions at any directory above the directory containing the file to be unlinked. If it is a UDF object, then you must, but otherwise that is not necessary. One also doesn't need Execute (X) permissions to that directory in order to use unlink. One needs Execute permissions in order to chdir() into that directory.

If I have Read and Write permissions to a directory, I can add and remove files all day long. Even if I have no permissions to the directory's parent.

James, did you ever read the link that I posted earlier? I suspect
you're still NOT checking the directories in the path that precede
your file object. EACH of the directories in your path MUST have at
minimum *X, the directory that contains your file must have *WX, and
the file object itself must all *OBJEXIST authority...

Uh, (1) the directories that always behaved properly were direct
sister-directories to the one that was malfunctioning, i.e., in the
same
immediate parent directory, so path could not have been involved, and
(2) in the malfunctioning directory, the owners of all files created
after it began malfunctioning were explicitly locked out of object
authorities for their files, and (3) the malfunctioning directory had
no
authority line at all for the owner, and as soon as I added one, it
started behaving properly.

The only question remaining is how the owner's authority line for the
malfunctioning directory disappeared in the first place, and why its
absence would cause everything created therein to be created with an
owner authority line explicitly locking out the owner's object
authorities.
