PCNTL required?

[rfay]

I happened to see this in the site I added rabbitmq to:

Extension [PCNTL](http://php.net/pcntl) not present in PHP. Option rabbitmq_timeout is not available in the RabbitMQ consumer.

Does the config.rabbitmq.yaml (when converted to be ddev config) need to have webimage_extra_packages: [php8.x-pcntl] or something?

I was not aware of this requirement. Sounds like it makes sense to add this to webimage_extra_packages.

According to the comment here, #1 (comment)

How to add a package to webimage_extra_packages? :-)

[rfay]

You would add a config.rabbitmq.yaml with

webimage_extra_packages: [php8.<x>-pcntl]`

Using that technique I don't know how to get the right PHP version without installing lots of them. As a custom Dockerfile (.ddev/web-build/Dockerfile.rabbitmq) it can use an environment variable $DDEV_PHP_VERSION, https://ddev.readthedocs.io/en/latest/users/extend/customizing-images/#adding-extra-dockerfiles-for-webimage-and-dbimage

Tested with these php version:

$ php8.1  -i | grep pcntl
pcntl
pcntl support => enabled

$ php8.2 -i | grep pcntl
pcntl
pcntl support => enabled

$ php8.3 -i | grep pcntl
pcntl
pcntl support => enabled

Seems like php8.x ships with pcntl enabled by default.

extension_loaded('pcntl') returns empty, and phpinfo() does not show pcntl enabled.
From what i read it is disabled for php-fpm.

Happy to enable it, if you can tell me just how? :-)

You're the expert here :) It's quite possible that the Drupal module either has a command-line approach that uses pcntl or it's just silly. I don't even know what pcntl is. I also don't know what rabbitmq is :)

I'll leave this open until i know more about rabbitmq and it's php requirements.
