1097624 - Make mulet happy with e10s

Status: RESOLVED WONTFIX

(Firefox OS Graveyard :: Runtime, defect)

Description

[:gerard-majax]

In bug 1095451 we did a quick hack to get Mulet to start Gaia. We should rather fix the real bug asap.

It should "just" be about preventing loading shell.html in e10s tab.
I haven't looked at browser/ code to see how we could achieve that.

For example, we could tweak this function:
  http://mxr.mozilla.org/mozilla-central/source/browser/modules/E10SUtils.jsm#14
In order to somehow prevent loading shell.html OOP.

e10s test issue.

Just to be clear. What we want is for shell.html and the system app to run in the parent process in Mulet. And eventually for the system app to then use <iframe mozbrowser remote> in order to run actual apps in child processes.

Yes and that behavior is controled by another pref, this one:
http://mxr.mozilla.org/mozilla-central/source/b2g/app/b2g.js#298
  pref("dom.ipc.tabs.disabled", true);

That will be toggled to false once tests are green...
It is really independant from browser.tabs.remote.autostart and running tabs OOP.

That's a good start but there is still something going on.

Attachment: WIP patch

With this patch, automatically loading shell.html still does not work. Tab name is underlined, so I suspect it's already living in a separate process. But forcing the load with the chrome URL works.
