VisualWorks startup sequence

Hi:

I would like to know what happens when I start VW
visual.exe visual.im
up to when the VisualLauncher is ready for user interactions.

A link to documentation would be great. A high level description and some startup code to read would be good.

Similarly, what happens when I end my VW with "Save and Exit"?

Thanks,
Aik-Siong Koh

This should be a good starting point:

Snapshot>>postSnapshotBootstrap
        "We're returning from a snapshot, bootstrapping from a disk image. Start up everything."
        Subsystem markAllInactive.
        self signalSystemEvent: #earlySystemInstallation.
        Processor activeProcess priority: originalPriority.
        self signalSystemEvent: #returnFromSnapshot.
        ObjectMemory primInformSystemReady.

Application code can show an interest in the events:

update: aSymbol
"       aSymbol = #aboutToSnapshot ifTrue: [].  "
"       aSymbol = #finishedSnapshot ifTrue: []. "
"       aSymbol = #returnFromSnapshot ifTrue: [].       "
"       aSymbol = #aboutToQuit ifTrue: [].              "

You'd have to review the notification sequences. Keep in mind that during save and return the active process is bumped to highestPriority (in Snapshot>>preSnapshot).
