1023980 - Need a generic mechanism to send data to apps that they need immediately on startup

Status: RESOLVED DUPLICATE of bug 984050

(Core :: DOM: Core & HTML, defect, P3)

Description

[Ben Turner (not reading bugmail, use the needinfo flag!)]

We need to be able to send certain info to apps on startup to prevent them from immediately turning around and sync-asking for stuff on startup.

We already know of several sync child->parent messages that slow app startup down, so finding them and sending that info immediately should eliminate a bunch of dead time.

There's fullscreen at least (bug 1003848), also PSms things (see bug 952875 comment 11).

Vivien, at some point you had a list of such messages, right?

I believe that the spot we'll want to modify in the parent->child direction is probably PBrowser::SendLoadURL...

The one I was looking for were:
http://mxr.mozilla.org/mozilla-central/source/dom/ipc/PBrowser.ipdl#218
http://mxr.mozilla.org/mozilla-central/source/dom/ipc/PBrowser.ipdl#218
http://mxr.mozilla.org/mozilla-central/source/dom/ipc/PBrowser.ipdl#278

There was also bug 1003848 as cited already.
IIRC that's all what I was seeing as obvious sync calls while starting the template app.

I fix this issue implementing the persistent registration of Service Worker. Now in LoadURL we have a BrowserConfiguration object that can be used.
