Changed to worker mpm

Posted on 22.05.201022.05.2010 by mario

Today I changed my server to from prefork mpm to worker mpm.

There are only some issues: in my phpmyadmin I had to set auth from http to cookie. And PHP_ADMIN_VALUE don’t work in the vhosts.

How to install it:

sudo apt-get install apache2-mpm-worker libapache2-mod-fcgid

In the single vhosts

Options Indexes ExecCGI
AddHandler fcgid-script .php
FCGIWrapper /usr/lib/cgi-bin/php5 .php

So that isn’t hard to do.

Well I would like to have a windows server with apache which is also threaded like worker mpm, but there is no cheap hoster for that yet. At home have that server is not an option cause of the small upload I have with my DSL, the coast of energie and where the hell should I put that server in my small apartment to that I still can sleep?

	    $current = $stop_time[1] - $this->timing_start_times[$name][1];
	    $current += $stop_time[0] - $this->timing_start_times[$name][0];
	    return $current;
	}

}

Test Inline Tags vs echo



< ?php $bm->timer_start('echo'); ?>
< ?php
for ($i=0; $i<1000; $i++) {
    echo $i."

}
?>
< ?php $bm->timer_stop('echo'); ?>

< ?php $bm->timer_stop(str); ?>


 < ?php $bm->timer_start(inline); ?>
< ?php
for ($i=0; $i<1000; $i++) {
?>

< ?php
}
?>
< ?php $bm->timer_stop(inline); ?>





Result

echo - < ?php echo $bm->timer_result('echo'); ?>

remove /MACHINE:X86 from make files with php

Posted on 13.03.201013.03.2010 by mario

I use PHP on the command line cause I know it the syntax better than any other scriting language and it works on linux and windows. This is about removing the x86 to be able to build apache in x64 (64 bit) on windows.

<?php
$files=array(
 "srclib/apr/libapr.mak",
 "srclib/apr-iconv/build/modules.mk.win",
