Description Dimitri Glazkov (Google) 2012-04-27 13:04:17 PDT
It's possible this is for Chromium/V8 only, but these tests are timing out frequently.

Arv, cc'ing you in hopes you know who to cc on V8 side.

Are those charts for Chromium or the Mac port, or both?

Only Chromium. I don't know if the flakiness is present on other ports -- don't have the data.

I haven't seen evidence of flakiness on JSC.

Danno: Do you know who worked on ByteArrays?
Comment 5 Daniel Clifford 2012-05-02 08:29:54 PDT
I did the Crankshaft implementation of ByteArrays in V8, so I'm probably the right person to take a look at this. I am not sure how to decode the included links, I'll follow up with Dimitri to figure out exactly what I have to look at.
Comment 6 Adam Klein 2012-05-25 15:16:15 PDT
Fwiw, these only seemed to be timing out on Debug builds, and usually take a long time even when they don't time out, so I've marked them as DEBUG SLOW and expect they'll pass in future (though will take awhile). See http://trac.webkit.org/changeset/118573
Comment 7 Yuta Kitamura 2012-08-15 00:10:50 PDT
Tests named dfg-*array.html are known to be slow. All these tests now point to
BUGCR24182 (Slow WebKit tests that pass):

<http://trac.webkit.org/changeset/125652>

I'm closing this bug as obsolete.
