71379 - late-loading activation ?

Status: VERIFIED INVALID

(Core Graveyard :: Profile: BackEnd, defect)

Description

[Cathleen]

activation is one of the components that gets loaded at start-up.  Is it 
possible after the very fist time, we don't load it anymore, or we lazy 
initialize it?

Comment 1

[Conrad Carlen (not reading bugmail)]

Yes, it's possible not to load it. And fairly easy too. What's the purpose here?
To save loading a component?

Comment 2

[Cathleen]

purpose is to help save start-up loading and memory page space.  :-)

Is the activation stuff initialised in Mozilla even though only Netscape 6 uses
this feature?
or should this bug be marked nsonly?
If this is initialised and not used by Mozilla I think this should be fixed soon

Yes. The profile mgr which is common to both causes it to load - indirectly
because there can be no reference to activation in the mozilla tree. This isn't
an issue for mozilla because the activation component will not be available, so
not loaded, etc.

It is nsonly - adding keyword.

-> mozilla1.0

We'd like to pull this into mozilla0.9.1 if possible.  Bhuvan, can you help? 
Seems like this should be a pretty simple fix.  We need to eliminate everything
we can from the startup - the only way to win is to nibble off all the little
pieces.

An instance of the activation component is created when the app is started with
a profile. The activation component determines whether it has to do anything or
not. Most of the time, it doesn't so it's created needlessly. If the profile mgr
could know whether the profile it is making the current profile needed
activation or not, it could skip this unless nescesary.

Bhuvan, is the true test of whether a profile needs to be activated done with
this: http://lxr.mozilla.org/mozilla/source/profile/src/nsProfile.cpp#2212?

This will take some changes to activation and should be moved to bugscape.

Since nsonly and patch will require change to nsonly code, moved to bugscape bug
8046.
