Navigation Timing

Jatinder: There were four pieces of feedback to this spec in the last few weeks.

[NavigationTiming] Uniqueness requirement for PerformanceTiming doesn't make much sense - http://lists.w3.org/Archives/Public/public-web-perf/2012Jun/0047.html

Jatinder: Zhiheng made the proper spec update here and resolved the issue.

[NavigationTiming] Not sure what the spec text about sorting PerformanceTiming objects means - http://lists.w3.org/Archives/Public/public-web-perf/2012Jun/0049.html

Zhiheng made the proper spec update here as well.

James: I saw that, yes.

[NavigationTiming] Issues in the document.open test (or perhaps in the spec, if the test is correct) - http://lists.w3.org/Archives/Public/public-web-perf/2012Jul/0022.html

Jatinder: To resolve the issue of ensuring document.open/.write/.close does not impact Navigation Timing and defining what is a navigation in Navigation Timing, can be achieved by referencing http://www.w3.org/TR/html5/single-page.html#navigate in the Navigation Timing spec.That reference excludes dynamic markup insertion. Zhiheng to make that update.

James: That looks like a good update to me.

Unclear note about "maintain the DOM structure of the document in memory" - http://lists.w3.org/Archives/Public/public-web-perf/2012Jun/0029.html

Jatinder: I believe we were trying to capture the scenario when traversing from a bfcache and not hitting the network, we shouldn't update the timing data for that page from when it had initially hit the network. I believe the definition of navigation doesn't explicitly include history traversal. If so, this might be out of scope anyway. I will close loop with Boris.
... Considering all feedback has been responded to, I propose we take this spec to PR next week and schedule the call with the Director.

James: I agree that there aren't any additional pieces of feedback.
... Let's take this spec to PR.

Performance Timeline

Jatinder: Seeing that Performance Timeline has been stable and has had no feedback for quite some time, I propose we take this spec to CR next week and schedule the call with the Director.

James: I believe we agreed to that two weeks ago. Let's move it to CR next week.

Resource Timing

Jatinder: I have responded to all feedback on the Resource Timing spec. As this spec is already in CR, we should start working on a test suite and implementations.

James: I have been working on a test suite for this spec. I will move them to the submission folder. Can you review them?

Jatinder: Yes, I can review them as soon as they are available. Thanks,

User Timing

Jatinder: User Timing spec only has one piece of feedback remaining and that is to review the getMarks/getMeasures APIs as they are redundant.
... I don't like the argument of sticking with generalized APIs vs specialized. We shouldn't restrict our API set on that principal.

James: I agree with that principal. I just don't think getMarks/getMeasures is the best example of specialized as they offer very similar data as the PErformance timeline provides.

Jatinder: Okay, let's make this change. I will respond to this Last Call feedback.

James: As there are no additional feedback and the rest of the spec has remained stable for some time, I recommend we take this spec to CR soon.

Jatinder: I agree. Let's schedule the call next week.

Page Visibility

Jatinder: As there is no outstanding feedback on this spec and the spec has been very stable for a long time, we have two implementations and a test suite, I propose we take this spec to CR.

James: If feedback has been met, I don't disagree.

Jason: Excellent seeing progress being made.
