nsIObserver topics for profile changing. Profile changing happens in phases
|
||
|
|
in the order given below. An observer may register separately for each phase
|
||
|
|
of the process depending on its needs.
|
||
|
|
|
||
|
|
"profile-change-teardown"
|
||
|
|
All async activity must be stopped in this phase. Typically,
|
||
|
|
the application level observer will close all open windows.
|
||
|
|
This is the last phase in which the subject's vetoChange()
|
||
|
|
method may still be called.
|
||
|
|
The next notification will be either
|
||
|
|
profile-change-teardown-veto or profile-before-change.
|
||
|
|
|
||
|
|
"profile-before-change"
|
||
|
|
Called before the profile has changed. Use this notification
|
||
|
|
to prepare for the profile going away. If a component is
|
||
|
|
holding any state which needs to be flushed to a profile-relative
|
||
|
|
location, it should be done here.
|
||
|
|
|
||
|
|
"profile-do-change"
|
||
|
|
Called after the profile has changed. Do the work to
|
||
|
|
respond to having a new profile. Any change which
|
||
|
|
affects others must be done in this phase.
|
||
|
|
|
||
|
|
"profile-after-change"
|
||
|
|
Called after the profile has changed. Use this notification
|
||
|
|
to make changes that are dependent on what some other listener
|
||
|
|
did during its profile-do-change. For example, to respond to
|
||
|
|
new preferences.
|
||
|
|
|
||
|
|
"profile-initial-state"
|
||
|
|
Called after all phases of a change have completed. Typically
|
||
|
|
in this phase, an application level observer will open a new window.
|
||
|
|
|
||
|
|
Contexts for profile changes. These are passed as the someData param to the
|
||
|
|
observer's Observe() method.
|
||
|
|
|
||
|
|
"startup"
|
||
|
|
Going from no profile to a profile.
|
||
|
|
The following topics happen in this context:
|
||
|
|
profile-do-change
|
||
|
|
profile-after-change
|
||
|
|
|
||
|
|
"shutdown-persist"
|
||
|
|
The user is logging out and whatever data the observer stores
|
||
|
|
for the current profile should be released from memory and
|
||
|
|
saved to disk.
|
||
|
|
The following topics happen in this context:
|
||
|
|
profile-change-net-teardown
|
||
|
|
profile-change-teardown
|
||
|
|
profile-before-change
|
||
|
|
|
||
|
|
See https://wiki.mozilla.org/XPCOM_Shutdown for more details about the shutdown
|
||
|
|
process.
|
||
|
|
||
|
|
NOTE: Long ago there was be a "shutdown-cleanse" version of shutdown which was
|
||
|
|
intended to clear profile data. This is no longer sent and observer code should
|
||
|
|
remove support for it.
