The prompt to allow or deny remote connections that landed in bug 758696 did not work for B2G, since the required platform API was missing, and we decided to implement it later. Vivien had posted a rough sketch of how this should be implemented in bug 758696 comment 8.
Need someone to implement this in B2G. GPS or maybe another Gaia dev?

Attached patch gecko patch (obsolete) — Splinter Review
This adds support for sending a debugger prompt request to gaia, and wait for the answer. The callback in Debugger.init() is a synchronous method, so we have to run the event loop there.

Gaia prompt, note that I had to add a new string.

How come this is commented? These are the b2g-specific overrides necessary to get the debugger to work in Firefox OS.

Attached patch gecko patch v2 (obsolete) — Splinter Review
Using #ifndefs in dbg-server.js didn't work (this prevented the debugger to start at all, and I tried many combinations).

With this patch, a successful connection to the devices doesn't offer any tabs or process in firefox desktop UI.

Hmm, weird. I wonder what was the error output.
This change will also work for what this patch is about, but will break the debugger server extensibility that you need for the app installation functionality that we discussed. If that's not a goal for now, I'm fine with it.

Ha no, that's not fine then. Can you investigate how to disable what we don't need? Meanwhile I'll make progress on our app installation actor.
Sure, I'll take a look tomorrow.

This does the trick. Now the only available actor in desktop-b2g is the profiler actor.

I will hold the review until you confirmed that the process can be closed in the described conditions.

Can you make sure this won't prevent the b2g process to be closed if there is a prompt opened and the user long press the home button in order to display the system menu and press restart?

Fabrice proves me that it works, so r+ with the small nit.
