Hi.
This post has also been posted on the Debian list.
I have two different Debian Etch machines running with the exact same
packages installed, when I use PHP memcached with compression (zlib) it
works at one machine but not the other. No errors are thrown.
I need to know why it is only working on one machine and not the other.
I am talking about the MEMCACHE_COMPRESSED flag if anyone knows about
this.
I am using this small script to test with:
<?php
error_reporting(E_ALL);
$memcached = new Memcache;
$memcached->connect('localhost', 11211);
$version = $memcached->getVersion();
print ("<p>Memcached version: ".$version."</p>");
// $memcached->flush();
$output = $memcached->get('var_key');
if (empty($output)) {
$memcached->set('var_key', 'Hello I am Memcached',
MEMCACHE_COMPRESSED, 3600);
print ("Memcached has just been set!");
} else {
print ("Memcached is already set with this value:
$output");
}
?>
If I disable the compression flag (using the 'false' value or zero
value) on the failing machine, all works correctly, but when I enable
it like in the above script it fails without error.
I have also tried running memcached with "-vv" options, and checked the
log, but no errors show up.
I am suspecting that zlib isn't working right on the failing machine,
but using phpinfo() it shows that zlib is enabled.
On both machines the following packages are installed:
ii libcompress-zlib-perl 1.42-2
ii libio-zlib-perl 1.04-1
ii zlib1g 1.2.3-13
ii libapache2-mod-php5 5.2.0-8+etch13
ii php5 5.2.0-8+etch13
ii php5-common 5.2.0-8+etch13
ii php5-gd 5.2.0-8+etch13
ii php5-imagick 0.9.11+1-4.1
ii php5-memcache 2.0.1-1.1
ii php5-mysql 5.2.0-8
+etch13
ii php5-pgsql 5.2.0-8+etch13
Any help in understanding what is going on would be greatly
appreciated.
Best regards.
Rico
