Semaphore extension

[sumachaa]

getting the below error when using this, please let me know how we can address this

+ vendor/bin/acquiacli app:list

Confirmed. Getting this as well on a fresh install. PHP 7.2

Thanks for the PR, I've merged it in.

That fixes only the warning. I still get this:

./vendor/bin/acquiacli setup

@shelane thanks for that. I wonder if this is similar to the issue the folks are seeing over here: contao/contao#337

Is it possible your local PHP wasn’t compiled with sysvsem?

I'm using the Docksal php 7.3 image
https://github.com/docksal/service-cli/blob/develop/7.3/Dockerfile

It does not look like it is.

[typhonius]

If they’re unable to add, we could look at using FlockStore instead of SemaphoreStore as that uses the file system rather than PHP.

I’ll keep this issue closed, if you hear back from docksal and still need support here, could I ask you to open a new issue and we’ll track it there.
