1569630 - Profiler popup should provide an easy way to profile all threads

Status: RESOLVED FIXED

(DevTools :: Performance Tools (Profiler/Timeline), enhancement, P2)

Description

[Greg Tatum [:gregtatum]]

There is confusing behavior around profiling all threads. We should make this easy.

When trying to profile all threads, I put in *. This seemed to do something at first, because Activity Monitor reported increased CPU usage, but then I captured the profile and it said:

Error: No threads were captured in this profile, there is nothing to display.

*, works perfectly however.

I just want to note that the "*" issue was recently solved in bug 1604661.

In this bug here, Michael will helpfully make it even easier, by adding a visible "all registered threads" option in the popup.
