global pools

["Roy T. Fielding" <fi...@ebuilt.com>]

Once upon a time, httpd would create a global pool as the result from
alloc_init and use that pool as the parent of almost all of the other
pools (I say almost only because there is one pcommands pool that was
separate, though I don't know why).

Now, httpd tells apr to initialize itself and alloc, but doesn't
get the global pool in return.  httpd then needs to create other
global pools.  I think this is leading to cases where the proper
cleanups are not being done, but its a little hard to tell because
there isn't much in the way of continuity (pools are created in
subroutines, assumed to exist at a higher level, and then destroyed
in other places).  Yuck.

Is there some reason that apr can't give us the global pool, or allow
us to give it the global pool?

I can't think of one, so I'd be fine with seeing apr_initialize() return a
global pool.

I can't think of one, so I'd be fine with seeing apr_initialize() return a
global pool.

I don't know of such a reason... I think that the thing to do would be
to have apr_initialize() return a pool, not take a pool (your second
choice).

Since apr_initialize() parmlist are to be changed this is probably the
time to add the version check.

       apr_initialize(&p, APR_???);

I don't recall exactly what Greg Stein wanted...

i suppose pcommands data could be allocated in pglobal instead...
