move to agenda 1

We agree that to decrease default buffer size to 150 from 1000

Made the change to remove fetchEnd and made secureConnectionStart optional

Made the change to remove getResourceTimingsByType method

Suggest removing the last sentence in the definition of responseEnd, as we are now only showing responseEnd and not fetchEnd:

Remove this sentence from responseEnd: “If the last non-redirected fetch of the resource is not the same origin as the current document,responseEnd must return zero unless the Timing-Allow-Origin HTTP response header rules apply.”

We all agree with this change.

Zhiheng: In 4.2 "Downloadable resources that are retrieved from the user agent's cache must be included in the PerformanceResourceTiming interface."
... this seems to contradict the first example.

Nic: The first example can be made a bit more clear what kind of cache item is not being included.

Action Nic to update the first example in Section 4.2 to make the cache item clear.

<trackbot> Created ACTION-27 - Update the first example in Section 4.2 to make the cache item clear. [on Nic Jansma - due 2011-05-18].

Action Nic to add SVG to Section 4.1

<trackbot> Created ACTION-28 - Add SVG to Section 4.1 [on Nic Jansma - due 2011-05-18].

Zhiheng: * In 4.3, We need more clarification about the accessing model about redirectStart and redirectEnd.

Action Jatinder to update Section 4.3 and Processing Model to refer to Timing-Allow-Origin header section.

<trackbot> Created ACTION-29 - Update Section 4.3 and Processing Model to refer to Timing-Allow-Origin header section. [on Jatinder Mann - due 2011-05-18].

The WG agrees that we should spend the next two weeks looking into the spec and preparing to enter Last Call. We should forward the spec to all interested parties for feedback.

move to agenda 2

Tony and James to follow up with a proposal to make the measure API more coherent with the marks concept.

<Christian> can we rename +1.650.253.aacc to [Google], like [Microsoft]?

<Christian> thx

<BWeigand> Can +1.503.712.aaaa be marked as [Intel]

<plh> zakim won't remember those btw. it needs.

Let's target FPWD for the Resource Timing spec for two weeks from now.

<plh> s/needs further intervention for that/

move to agenda 3

<jamesr> cool

1. We are all leaning towards document.visible. Jatinder to analyze data to see which of the following names to use for PageVisibility: window.visible, document.visible, window.pageVisible and document.pageVisible.

We are okay with not supporting onvisibilitychange.

Making prerender and preview states as optional.

Using DOMString constants instead of unsigned short constants

scribe: Need constants to allow web developers to inspect for capability
... webIDL spec, http://dev.w3.org/2006/webapi/WebIDL/#idl-constants, allows for DOMString constants

Don't believe we need to require PAGE_OTHER. UA can always add prefixed state.
