Bug 102380 – Web Inspector: http/tests/inspector/stacktraces/* are flakey in JSC

• Status: RESOLVED
• Resolution: FIXED
• Component: Web Inspector (Deprecated)

[Mike West]

http://test-results.appspot.com/dashboards/flakiness_dashboard.html#group=%40ToT%20-%20webkit.org&showExpectations=true&tests=http%2Ftests%2Finspector%2Fstacktraces%2F shows the story.

Half the time the trace looks like:

    0) http://127.0.0.1:8000/inspector/stacktraces/csp-injected-content-warning-contains-stacktrace.html / thisTest / 12 / 0
    1) (internal script) / eval code / (line number) / (column number)
    2) [native code] / eval / 0 / 0
    3) [native code] / evaluate / 0 / 0
    4) (internal script) / _evaluateOn / (line number) / (column number)
    5) (internal script) / _evaluateAndWrap / (line number) / (column number)
    6) (internal script) / evaluate / (line number) / (column number)

The other half, it looks like this:

    0) http://127.0.0.1:8000/inspector/stacktraces/csp-injected-content-warning-contains-stacktrace.html / thisTest / 12 / 0
    1) (internal script) / eval code / (line number) / (column number)
    2) [native code] / eval / 0 / 0
    3) [native code] / evaluate / 0 / 0
    4) [native code] / call / 0 / 0
    5) (internal script) / _evaluateOn / (line number) / (column number)
    6) (internal script) / _evaluateAndWrap / (line number) / (column number)
    7) (internal script) / evaluate / (line number) / (column number)

The traces are identical, except for line 4.

I'm not sure why this happens; I'm tempted to change the test to only check the top frame of the trace.

The failure looks unrelated, and doesn't reproduce locally. I'll land it; if it dies on the main waterfall, I'll roll it out.
