Check job is running before call.

[orolyn]

It would be useful to me to know that a job is actually running before calling it.

I have created a simple class (a bit of a mash up, forgive me) which checks that a single job is available.

Most of the data transfer is copied from net_gearman, but this is tied in to retrieve the servers from GearmanCacheWrapper so multiple servers can be checked.

If this is functionality you think would be useful, how do you reckon it should be implemented?

Personally I would like it is when running a task/job, the client through a special exception.
The inconvenience at the moment (and this is about work distribution in general, not your project) is when running a do synchronous, the script will simply hang. Id like there to be some immediate feedback that something is wrong with either the worker or the daemon.

Is this the issue you wanted to solve in the last PR #118?

[orolyn]

No, this was for the client's benefit.

I would have liked the client to know that the job is available prior to attempting a job on it. It only applies to cases where immediate confirmation is required in order not to disrupt workflow.

Otherwise the client will hang until either the daemon comes back online if it was offline or the worker is started.

The reason i made a gist was because I don't know how this would fit into the client class.
Since this bundle integrates the gearman extension with symfony as opposed to creating a superset, I wasn't sure you would like it.

I would have liked the client to know that the job is available prior to attempting a job on it.

I don't understand ... what is the use case?

[orolyn]

In my case I am running a background task after an Ajax call.
The script then repeats status check Ajax calls to animate the progress bar.

However if the daemon is down, or the worker is not started, that Ajax call will just hang there.
It is better for me if it simply informed the user that they cannot run that process right now.
