All of the changes I'd like to introduce below impact one another, and are based on several basic premises;
1. A sub_req_lookup() caller (of any flavor) should be able to make heads or tails of the request based on the processing that occurs within ap_process_request_internal(). 2. No handler should die on known 'stuff', e.g. headers, etc, when those decisions can be made upfront, during the ap_process_request_internal() cycle. A sub_req call can then choose some alternate resource (such as going on to the next entry in the list of DirectoryIndex documents). Dying for reasons we, couldn't determine up-front, such as mis-submitted POST data, remains always acceptable. 3. Namespace polution is evil. Ergo, any module should reject requests for a document with path_info if it doesn't address the name space passed in path_info for the request. This leads to several individual patches that I'm writing. . My mod_dir patch which performs the entire internal handling of dirs within the fixup hook. It has an associated patch to restore autoindexes' correct behavior {posted 12/2, Message-ID: <021e01c17bab$a9d076c0$93c0b0d0@v505>} . Patch in HOOK_LAST of ap_run_fixups; punt the *handler to core if the thing is a file, and the proper path_info conditions exist, and punt no-file to NOTFOUND and no-handler cases to 500 misconfigured. . Hooks are _not_ the fastest things in the world, especially with the strcmps around ->handler going on. If we resolve the ->handler up front, why not provide a ->handler_fn member that skips the entire handler() hook walk? . Add DefaultHandler [AcceptPost|RejectPost] [AcceptPathInfo|RejectPathInfo] The default to both is, Reject. This setting is noted, but not acted upon, until we hit the HOOK_LAST of fixups. . php and others may then toggle the setting for Post or PathInfo in their setup hooks, so they can superceed the user .conf setting or the defaults. . move ap_run_insert_filter to the run_subreq code, so we get that possibly expensive hook into the content. Since it can't fail, it doesn't need to sit up in the lookup logic. Comments? Bill
