[youenn fablet]

This would allow not creating a service worker process if there is no need for it.

Patch tested locally and it waits to create a service worker for a page to match.

[youenn fablet]

Would need API test probably.

We no longer need this part if we land the patch at Bug 182375 first.

This seems weird. This is called due to IPC iirc. Therefore, I would expect this method to not be virtual and be on WebSWServerConnection instead.
Also, it looks like you kept SWServer::Connection::scheduleJobInServer() in the cpp?

I do not think we need this method on SWServer::Connection.

> +    scheduleJob(WTFMove(jobData));

we can call server().scheduleJob(WTFMove(jobData)); directly, like we do in the other methods. No needs for a scheduleJob on Connection.

Initially I did that, I kept it there as there is some logging done in SWServer.
I can convert it to release logging in WebKit2 code.
