Getting at server's MaxClients setting?

["Bas A.Schulte" <bs...@zeelandnet.nl>]

Hi,

is it possible to get at the configured MaxClients setting from within 
my handler?

I checked Apache::Server which gives you some configuration information 
but there's no accessor for MaxClients.

Any other, easy, way?

nope, you didn't miss anything.  unfortunately, mod_perl 1.X does not 
offer up the entire Apache API to perl land (though the intent of 2.0 
is to do just that).

actually, I just whipped up a module that offers get/set for MaxClients:

http://www.modperlcookbook.org/~geoff/modules/experimental/Apache-MaxClients-0.01.tar.gz

it's not perfect (it doesn't offer the checks that the MaxClients 
directive does), but it seems to work.  with a little effort, I 
suspect it could be worked out so that you don't need a request 
object, but rather an Apache::Server object.  however, it shows how 
easy mod_perl makes it to open up the Apache API where you need it.

Well, for the moment, I'll grep for it in the current httpd.conf ;)

Just thought I'd ask in case I was missing something obvious.

Thanks,

Bas.

see my previous post from earlier this week :)

in this case, MaxClients looks like it calls ap_daemons_limit to make 
the setting, so you may be able to create a subclass that offers up 
that API to perl-land.  for more information on how, you can check out 
the slides from my recent ApacheCon talk:

hmm... sounds like another good idea to add to my next talk :)
