WP-CLI and WooCommerce

Hello, do not rename the object-cache.php!
Docket Cache is not related and you should not run multiple cache plugins at the same time.
Redis is a different story –?but the problem you face could be related, as the extension needs to be activated for CLI.

Set
apc.enable_cli=1
in your php.ini or conf.d/20-apcu.ini

Then put this into a script file and run from cli.

<?php

$apcu_cache=apcu_cache_info(true);

if ($apcu_cache)

{

$apcu_mem = apcu_sma_info();

echo 'APCu memory: ', ($apcu_mem['num_seg']*$apcu_mem['seg_size']), ' bytes.';

echo "\n";

$testKey='atec_apcu_test_key';

apcu_add($testKey,'hello');

$success=apcu_fetch($testKey)=='hello';

if ($success) echo 'APCu is writeable.';

else echo 'APCu writing to cache failed.';

echo "\n";

if ($success) apcu_delete($testKey);

}

?>

Thank you for the fast reply, I added that line in php.ini for the current version of PHP I’m using, because it wasn’t there already, but it still doesn’t work and throwed the same error. Should it be already there set to 0, or I should write it in a specific location?

run

php --info|grep APCu

and see what happens, looks to me like you do not have apcu enabled at all.

Returns nothing indeed, but still the plugin is active, Query Monitor detects it, and queries are actually cached. Also, the error above shows it should be enabled since it interferes with the script…

the plugin will only install the object-cache if APCu is enabled.

if (extension_loaded(‘apcu’) && apcu_enabled())

Maybe your config changed in the meantime.
But you should get an error message on the atec-cache-apcu dashboard that APCu is not enabled.

As you can see here:

https://ibb.co/SyjNVpm

the object cache is activated.

well then something is wrong with your setup.
did you restart php after changing the php.ini ?

I restarted Apache, what do you mean by restarting PHP? Could you provide the command?

depends on your config and os.

I was able to solve the issue, here is how in case someone else will need it:

Even if Query Monitor said the APCu extension was enabled, there wasn’t any extension=apcu.so line in php.ini, so I added it. Now php -i | grep apcu gave the error

PHP Warning: PHP Startup: Unable to load dynamic library ‘apcu.so’ (tried: /usr/lib/php/20230831/apcu.so)

So I actually installed the APCu extension for my current PHP version with

sudo apt-get install php8.3-apcu

And now the grep command above said apcu was already enabled in /etc/php/8.3/cli/conf.d/20-apcu.ini, so I deleted the line in php.ini and added apc.enable_cli=1 in 20-apcu.ini. Now It works perfectly.

good.
like i said, there is an issue with your apcu config.
.ini files in conf.d folder are loaded when php.ini is loaded, so you can please the option in either one but not in both files.

of course i could ask if apcu exists with every call but that would slow things down – and the object-cache i have written is the fastest cache compared to any other solution.

see here.

Can’t even argue, it gave amazing performance from the start (products page generation time from 2.10s to 0.50s) and apart from this, I had no fatal errors during navigation on backend like it used to happen with Redis (even though I don’t know if I misconfigured it, I know of many cases of corrupted data or broken sites). I’ll consider using your plugin on my other website as well. Keep up the good work and thanks for your help!

you are welcome.
would appreciate a positive review.
and try the other plugins too!

I will certainly do both.

great.
tnx!
