Bug 31133 – Web Inspector: Add console.getProfile function

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

[David Boyer]

This functionality is implemented by FireUnit plugin for Firefox (FireUnit is an addon that modifies Firebug)

The function would return a JavaScript object that represents the profiling data.

And example dataset would be : 

{ 
  calls : 200, // # of calls
  time : 200.00ms  // total time of profile
  data : [
    { 
     avgTime : 9.525, 
     calls : 9, 
     fileName : "test.js", 
     maxTime : 25,
     minTime : 8,
     name : "doSomethingFunction",
     ownTime : 85.727,  // Time executing in me (not child functions)
     percent : 26.21,
     time : 85.727  // Total time spent in me (and child calls)
   },
    <...>
  ]
}

Can't find the function documented in fireunit plugin, but it's there.
I'm making the same request at Firebug, to move this from the fireunit addon into the firebug addon.

Ideally the result js from the two functions should be identical.

Seems like good timing if this is not yet in FireBug proper.  We should coordinate with the FireBug devs to coordinate on the format.

This information is already available via 'console.profiles' array. Here is a reduced output sample from console:

console.profile("aaa")
console.profileEnd("aaa")
console.profiles[0]
Profile
  _profilesTreeElement: Object
  children: Array
    0: ProfileNode
       callUID: 619779680
       children: Array
       functionName: "(program)"
       lineNumber: 1
       numberOfCalls: 13
       selfPercent: 0.02909303036682285
       selfTime: 2.383056640625
       totalPercent: 0.02909303036682285
       totalTime: 2.383056640625
       url: ""

Also please mind that in Firebug profiles are flat (no callee / caller information is exposed), while in Inspector a call tree is exposed in a profile.

I think we can call this resolved now, right?

Since console.profile() is doc'd by FireBug and WebKit now.

Not quite. This issue is about adding a new function 'console.getProfile'.

[Rob Colburn]

Ah, it sounded like David was just asking for the data of 'fireunit.getProfile()', which is now available.

The FireUnit project hasn't been actively maintained for some time.  I wonder if it would be reasonable to build the same extension for Web Inspector, now that Web Timing is spec'd and implemented in WebKit.

It would seem that @jeresig and team moved on from the project to TestSwarm and such.

Is there any additional functionality that FireUnit provides that is unattainable in WebKit.

Btw: seems like the best docs are on @jeresig's site http://ejohn.org

Closing as invalid, as this bug pertains to the old inspector UI and/or its tests.
Please file a new bug (https://www.webkit.org/new-inspector-bug) if the bug/feature/issue is still relevant to WebKit trunk.
