273417 - Make toolkit code use the app id, app version, app buildid from nsXULAppAPI instead of requiring prefs.

Status: RESOLVED FIXED

Description

[Benjamin Smedberg]

We now have a scriptable interface version of nsXULAppAPI. To make app setup and
bootstrap more sane, we shouldn't require the app id/version/buildid in prefs
also. This patch fixes things.

yes, make it so :)

ditto

memset(&id, 0, sizeof(id));

For interfaces that expose an nsID getter, we often provide a noscript
version that returns a shared pointer (nsIInterfaceInfo::getIIDShared)


r=darin with those changes

Fixed on trunk, without the noscript iid-getter. We don't have any non-scripted
callers yet, and it doesn't look likely that we will. I can add one later if
necessary.

Right now the comment says it's unstable.  Is there any timeline when this will
be stable?  SeaMonkey 1.8?  Firefox 1.1?  Or is this further out?

Comment 5

[Benjamin Smedberg]

Yes, I intend to have a stable interface by 1.8/1.1, and it is likely that I
will try to freeze it.

Comment 6

[Robert Accettura [:raccettura]]

Cool.  I could make good use of that appBuildID.

The patch seems to have ommited one gPref.getCharPref(PREF_EM_APP_VERSION) ->
gApp.version (

Dorando, thanks for noticing that, I have fixed it also.
