818382 - Support chrome debugging in Firefox for Android

Status: RESOLVED FIXED

(DevTools :: Debugger, defect, P3)

Description

[Panos Astithas (he/him) [:past] (please ni?)]

As far as the remote debugging protocol is concerned, chrome debugging is mostly a global thread actor that has visibility to all JS running in the application process. We should add such capability to Firefox for Android in order to make debugging mobile add-ons easier, as well as help debugging Firefox itself.

Attachment: Patch v1

Same patch more-or-less as bug 818385. With this patch, when I connect remotely to Fennec and select Main Process form the target list, I now get a working debugger. The script list displays all the scripts loaded in all JavaScript globals (even JNI.jsm - oh, the memories!). I observed the protocol interactions while adding/removing breakpoints, etc. and it seems to work fine, albeit (dog) slow, like chrome debugging on desktop.

Not sure how useful it will prove to be for our mobile developers, since I assume they mostly deal with Java, but I expect add-on developers to love it (probably after we fix our chrome-debugging bugs).
