Subject LUA hook ordering & block/section form
Date Mon, 17 Oct 2011 11:56:21 GMT
I'm thinking of tweaking mod_lua to allow most LuaHook* to run "early'
or "late".

Currently they all run APR_HOOK_MIDDLE which can be kind of limiting.

Would it be acceptable to just register three hooks for each phase
(early/middle/late) and continue to bail out quickly if no lua code is
registered?  Or  does it need to be smarter about registering the
hooks as the admin asks for "early" or "late" scripts or blocks?

I am tentatively using APR_HOOK_FIRST-1 and APR_HOOK_LAST+1 for the
alternate ordering, since you can't provide predecessors/successors
and APR_HOOK_FIRST would still have you bumping into e.g. mod_rewrite.
APR_HOOK_REALLY_FIRST/LAST also seems like it would step on the toes
of things (in an unpredictable way).

If we let the user pick an exact order (but still no
predecssors/successors) I guess we could register the exact hook
ordinals as we see them but this seems like too much.

Also, is there any reason the block/config-section forms of each Lua
directive are not documented?
