That's a very interesting module - thanks for the pointer!
I was wondering if anyone had suggestions / recommendations for a
run-time application configuration mechanism for mod-perl apps. What I
am thinking of is simply a way to communicate new application settings
to all of the mod-perl children.
The only solution I can think of is to have all of the mo
I am wondering how time spent in a cleanup handler affects page response time.
For instance, if I do a sleep(1) in a cleanup handler, will my page
delivery times be increased by a second?
Or will other available mod-perl child processes pick up pending
requests until the cleanup handler returns?
Hi all,
I've been playing around with modperl and attributes. Below is the
module I am experimenting with.
When I start up the server I see the warnings coming from the
MODIFY_CODE_ATTRIBUTES routine.
However, when I fetch the url associated with the handler, it reports
that ATTRS = {}.

Hi Torsten,
So is this what you are suggesting...
Define $MAX_SIZE to be the largest length of POSTed data you will accept.
For modperl <= 2.0.4 just use a single read and hope for the best:
$r->read($buf, $MAX_SIZE);
For modperl > 2.0.4 ( >= 2.0.5?) using this while-loop works:

Hi all,
On x86_64 I noticed that perl .so files (XS modules) appear to use a
lot more memory than they do on 32-bit architectures.
In particular, /proc/$$/smaps reports a ~ 2MB segment associated with
the .so library that is not reported in the 32-bit case.

I'm trying to figure out how mod_perl and mod_rewrite work together.
This is with Apache 1.3.41, mod_perl 1.30, perl 5.8,9.

a mod_rewrite rule rewriting that location to another doesn't have any
effect.

Hi,
I have a problem where a mod_perl handler will allocate a lot of

I'm trying to use Smart::Comments with mod_perl. The problem is that
STDOUT and STDERR are blessed into the Apache class and they do not

I was wondering how graceful restarts of apache interact with modperl

Specifically, if the apache parent process loads module Foo.pm, and I

My concern is about what happens in this scenario:
One operational issue with this is that if the logger process dies,
existing httpd processes will get a SIGPIPE signal on subsequent
writes. Restarting the logger process does not restore the lost
connections.

I know that you can use CustomLog with a pipe. However, will that

mod_perl doesn't use Perl's filter layers. $r->print is an octet
