Andrija Vu?ini?

Hey @ekkljs,

here’s the code that reads the memcached servers: https://plugins.trac.www.ads-software.com/browser/memcached/trunk/object-cache.php#L834, and here’s where it checks for a socket: https://plugins.trac.www.ads-software.com/browser/memcached/trunk/object-cache.php#L852.

Hope that helps.

> Looks like Memcached freezes soon after it starts and gets 1000-4000 hits/misses.

Do tell what was the problem when you figure it out. ??

Fatal error: Maximum execution time

This is a PHP error. I’d suggest increasing max_execution_time to check whether it ever finishes.

It times out on this line https://plugins.trac.www.ads-software.com/browser/memcached/trunk/object-cache.php#L176, which is trying to add some data to the memcached instance you’re running. Is this a clean WP install? Have you checked if your memcached instance is working?

That message means you don’t have the required extension installed: https://pecl.php.net/package/memcache.

Please mind that there are two extensions memcached and memcache. You need the memcache one.

When no access to SSH so can’t activate the plugin?

You can use FTP to copy the file, or a WP plugin like https://www.ads-software.com/plugins/wp-file-manager/.

Redis plugin only activated and goodbye.

Yeah, they overwrite the original file in code but we’d rather not. Also, most hosts provide these plugins as drop-ins for you. I’d say this one does need some dev knowledge (or at least understanding of what you’re doing).

Hey there,

did you follow the Installation steps provided here: https://www.ads-software.com/plugins/memcached/#installation ? I’m guessing you just installed it like any other plugin, but it doesn’t work like that. ??

Nice, glad to hear it!

They just looked at the release dates. memcache is fine, and works well (running it on a lot of sites).

But the most important question is, does it work now with PHP 8.0?

Just to be clear, don’t both of them need to be installed per your install instructions?

It can be confusing. The memcached we mention is the cache store server: https://memcached.org/. It is unrelated to PHP.

For PHP, there are two extensions. memcache and memcached. They are both extensions that allow PHP to communicate with the above mentioned cache store server. This plugin is developed specifically for the memcache extension.

Hope that helps.

Ah, ok. You need to have memcache installed, not memcached. Check the output for PHP 7.3.

Could you please do the same while on php 8.0? Trying to figure what is missing. Still think it might be old extension versions.

Btw. How did you install the extensions? Pecl?

Heh, that didn’t work. Let’s just run them as separate commands:

php -v

And

php -m | grep memcache

Don’t think it’s a configuration issue. If it works fine on 7.4, I’m guessing you’re using an outdated version of the plugin (no php8+ support).

Could you run this on your server and paste the output:
php -v && php -m | grep memcache

Hey there,

we’ve been running it on both 8.0 and 8.1 for a while now. That said, we use this extension https://pecl.php.net/package/memcache (as opposed to memcached, mind the last d). Could you give us some more info on your environment? Does php8 have the correct extensions?

Thanks @okvee. Released new version: https://plugins.trac.www.ads-software.com/browser/debug-bar/tags/1.1.3/debug-bar.php?rev=2716447
