While profiling Dromaeo, I noticed that the DOM Events tests don't actually seem to test DOM event handling, because JS code doesn't run fast there. Shark shows rather deep recursion of js_fun_call/js_Interpret/js_fun_apply and if I read that all correctly, tracing doesn't work there. (I was told that nested js_Interpret calls pretty much disable tracing) The actual event handling takes just few % in the test.

Shaver tells me that Jason has been working on a fix for the deep bail problem.

I assume this is a tracking bug? Bug 532696 and its dependencies cover the things I saw on the prototype tests last time I looked at them. We probably need to look at the abort logs and trace exit logs for jquery too. Smaug, were you going to do that?

I don't know how to look at abort logs or trace exits, but probably time to learn that.

> I don't know how to look at abort logs or trace exits Catch me on irc or e-mail and we can talk? Would love to have another DOM person looking at that sort of stuff. ;)

bz/smaug, is this bug still a valid non-TM bug or has DOM perf work moved on to other bugs at this point?

Would need to redo the profile from comment 0 to tell. Olli, can you do that, or should I?

I could re-profile.

Based on Bug 928318 the situation hasn't really improved.
