I see two problems with this:
(1) There is no such thing as "readable world" in the permissions of
Unix; the closest I can think of is the combination of user, group
and other permissions. Note that these are grabbed in order;
the user that own it CAN NOT read a file with permissions -wxrwxrwx.
Using permissions rwx---rwx is a trick that sometimes is used to
make sure that a particular group cannot get at data.
This is resolvable by renaming to readable_other? (which is the
correct Unix terminology - see
http://www.opengroup.org/onlinepubs/7908799/xbd/glossary.html#tag_004_000_107
for details). However, introduce another problem:
(2) If renamed to readable_other?, this is tied very closely to the
ancient Unix permissions systems. This isn't even correct for new
Unixes (ACLs are available), and definately not correct for Windows
et al.
Thinking a bit more about it while writing this, I wonder if the right
thing to do wouldn't be to extend the API with four calls instead of
two:
readable_world? - check for
(perm & (S_IRUSR|S_IRGRP|S_IROTH)) == (S_IRUSR|S_IRGRP|S_IROTH)
(that's the same as)
(perm & 0444) == 0444
readable_other? - check for
(perm & S_IROTH) == S_IROTH
(that's the same as)
(perm & 0004) == 0004
writable_world? and writeable_other? do the same for the write flags.
Introducing both of them has a couple of advantages:
- It make it obvious to people that there is a difference
- It provide at one call with semantics that can be used on
different permission systems
- It provide the functionality requested (which I agree would be
nice to have - I'd be annoyed if I discovered it was missing.)
