1159323 - [jsdbg2] The onGarbageCollection hook should fire for each slice instead of each cycle

Status: NEW

(Core :: JavaScript: Debugger API, defect)

Description

[Nick Fitzgerald [:fitzgen] [⏰PST; UTC-8]]

It turns out that the API would be easier for devtools API users if it were this way.

We would need to restructure the event data to something like

{
  // Whether this is an incremental slice, or not.
  isIncrementalSlice: true|false,

  // This would just be the major GC number, used to identify
  // which slices are related to each other.
  incrementalGCCycle: Number,

  // If nonincremental, string saying why.
  nonincrementalReason: null|string,

  // Short string describing why we are GCing at all.
  reason: string,

  // Timestamps for the start and end of this slice/collection.
  startTimestamp: timestamp,
  endTimestamp: timestamp
}
