Yes, I think your summary is pretty accurate. I never did really understand why mod_python works the way it does in this area (I'm sure there was a reason but I wasn't around then).. I always thought the Apache logic was a lot more useful. I am one of those who do make somewhat-significant use of the other apache phases. Actually what I've been doing is to essentially write my own "looper" wrapper, which looks like just one handler to mod_python, but which then implements more of an Apache-style loop/dispatch itself in sub-handlers. So at least in my case, I've been working around mod_python rather than letting it work for me. I guess the positive thing is that because of this I don't have any existing code which actually uses multiple mod_python handlers in the same phase; so this change in behavior is only positive for me. So for me it's +1 on Graham's suggested change in logic (but any incompatible change in behavior is something to think hard about). As for an example where this could even be benificial to the content phase, consider having different content handlers, one which outputs application/xhtml+xml+SVG+MathML and one for text/html+GIF. Then the first handler would look at the Accept header, etc, and if the user-agent can't support it, it returns a defer and then the text/html handler gets a chance. However, I still think even this new proposal is somewhat restrictive. For example there's no way to interleave C and python handlers in the list-to-try (this is because to apache all the mod_python handlers look just like one handler). Of course a necessary thing to go along with this, would be a way to specify the hook order (one of APR_HOOK_REALLY_FIRST, _FIRST, _MIDDLE, _LAST, or _REALLY_LAST). Perhaps mod_python can actually add multiple hooks to itself in for each phase (at each order position), and then have a way for the python-handlers to optionally specify a position. If mod_python had no handlers for a particilar hook position it would just by default return a decline. -- Deron Meranda
