728699 - error console logging for GC should indicate if incremental GC is disabled

Status: RESOLVED WORKSFORME

(Core :: JavaScript Engine, defect)

Description

[Andrew McCreight [:mccr8]]

This would be useful for figuring out what is going on.  Currently with (I'm assuming) incremental disabled there's no explicit indication that it is turned off:

GC(T+2096.4) TotalTime: 138.6ms, Type: global, MMU(20ms): 0%, MMU(50ms): 0%, Reason: CC_WAITING, +chunks: 0, -chunks: 0
mark: 103.6, mark-roots: 8.9, mark-other: 4.4, sweep: 32.0, sweep-obj: 6.1, sweep-string: 1.3, sweep-script: 0.6, sweep-shape: 5.0, discard-code: 2.1, discard-analysis: 8.2, xpconnect: 2.2, deallocate: 0.1

The lack of any information about slices, and the 0% MMU, is an indication, but given that this is an erroneous situation, it would be nice if it explicitly said that incremental GC is disabled.

thats not the point.

This was fixed at some point:

GC(T+91204.4) TotalTime: 165.7ms, Type: global, MMU(20ms): 0%, MMU(50ms): 0%, Reason: SET_NEW_DOCUMENT, NonIncrementalReason: incremental permanently disabled, +chunks: 0, -chunks: 0
mark: 111.6, mark-roots: 10.6, mark-other: 3.9, sweep: 52.8, sweep-obj: 6.8, sweep-string: 0.6, sweep-script: 0.7, sweep-shape: 4.4, discard-code: 2.4, discard-analysis: 28.8, xpconnect: 2.6, deallocate: 0.1
