Description Devin Rousso 2016-08-28 17:14:56 PDT
WebKit/WebKitBuild/Release/WebInspectorUI.framework/Resources/Views/TimelineRecordBar.js:232:23: CONSOLE ERROR
WebKit/WebKitBuild/Release/WebInspectorUI.framework/Resources/Views/TimelineDataGridNode.js:230:23: CONSOLE ERROR

Both lines are along the lines of:

I'm guessing that this may be due to the fact that secondsPerPixel is initially 0, which will trigger assertions.

These are mostly the fault of NetworkTimelineView, which wasn't clearing all its cached data on recording reset, and in addition didn't check that time stamps were actually changing before doing a layout. The latter resulted in trying to refresh graphs when endTime - startTime === 0, resulting in an invalid value for secondsPerPixel.

[Patch] Proposed Fix

This patch is missing a changelog. Ideally it would explain the sequence of events to cause this assertion and why the sequence is now different.
