Re: Time for 2.4.5 ??
That is true actually, new test system - will need to look at why 2.4.4 stumbled over that, while 2.4.x did not. Many thanks for the feedback.

"Forbid" directive in core?
I'd like to add an immutable Forbid directive to the core and use it in some places in the default configuration instead of "require all denied". http://people.apache.org/~covener/forbid.diff This protects from a broad
Location walk after directory walk?
Is there some historical or other reason that the location has higher precedence that directory/files?

Just a comment: other places that do broadly similar things often have a “deny by default” philosophy. I like this approach. Obviously this isn't going to please admins with existing configurations, so is there a way to design the mechanism so it's still possible to get something more strict than we have at the moment? In terms of directives, this could look like: # For example, insiset that exemptions must be defined in the same place as the Forbid is set. Forbid ForbidExemption /srv/web /nfs/foo/bar # Require HTTPS except from IPv4 localhost # Expression evaluation doesn't need exemptions Forbid -- Tim Bannister – is...@jellybaby.net

Why indeed in core? The interaction of different scopes - not least Location vs filesystem paths - is a source of regular confusion. I'm not sure adding another directive with different, one-off semantics helps. Does it really override / in all circumstances? Could it create (new) gotchas with Alias, internal Rewrites, or similar mapping functions? Also the comment "Irrevocably forbids access to the enclosing scope" could easily be read as going up a level in a hierarchy (it confused me momentarily, and I had the context of the complete patch to figure out what you meant by saying "enclosing" rather than "current" or just "this"). -- Nick Kew

Does Location supercede Directory/Files? My understanding is that if the Directory/Files says no, then the access is denied, regardless of what Location says. Or to state it another way, we are successful until the first directive comes along that says denied. We don't deny, and then later on change our mind and succeed again.

Re: Location walk after directory walk?
Historically on unix it was syntactic... would you rather control access in filepath space or uri space? It seemed pretty simple to grant read access, versus the so that was an early preference still used by some admins. With case-insensitive filesystems it became a real problem. Granting access by location is still simple (request the correct case pathname for the uri, or the case-sensitive grant-ACL will fail), but denying access became tricky. Trickier still because case-flexible filesystems are also usually flexible in other, non-intuitive ways, like the handling of a trailing period on an NTFS volume. So cannot be safely used to deny file access under several OS's, including several case-insensitive unix examples such as hfs+, samba shares etc. As with most historical artifacts, history often wins the debate over 'correctness'.

I think the other way is much more > intuitive Don't know about th real motivation, but after having learned that from the explicit description in the docs I got very used to it. Changing it would have major implications for existing configs. One nice thing i saw yesterday is an explicit recipe in our docs to put additional control on .htaccess stuff you don't want to happen by enforcing your policy ("fixing" problematic .htaccess) with a that merges later.

Have a > look at the end of > http://httpd.apache.org/docs/2.4/sections.html#merging I think the real problem is that AuthzMerging defaults to "off". Having a default of "and" would have been a lot safer, but that cannot be changed in 2.4 anymore. And there is not even a way to make AuthzMerging default to "and" globally. Time for a "DefaultAuthzMerging XXX" or an "AuthzMerging XXX inherit" directive?

Maybe mod_authz_core would be more appropriate? > And what is bad about "require all denied"? That it is too easy to override by accident. Actually, mod_allowhandlers in trunk allows SetHandler forbidden which more or less does what Forbid does (unless one overrides the Handler later on). But that's even more confusing than a separate Forbid. I am in favor of adding something that denies and is difficult to override by accident. But maybe the combination Require all denied AuthMerging and inherit would do the trick, denoting that later sections are merged with and unless AuthMerging is set explicitly. But I guess it could still happen that this would be overriden by accident by an "AuthMerging or" later on. Another possibility would be AuthMerging immutable stating that sections merged later would be ignored. But I can't think of any sane usage except with "require all denied". So maybe the Forbid is enough?

I don't know either, but I could imagine that it was just easier or more efficient to implement in this order, considering things like config walk caching, file-typed subrequests, etc.
