Web Performance Group charter

Todd: talked to Adrian before this call. as long as the charter covers the scope, without broadening it too much.
... as long as we have general deliverables, we should be fine
... CPU and memory is an example
... "solve the pb of understanding CPU and memory on the web page"

https://github.com/w3c/charter-webperf/pull/4

<igrigorik> https://rawgit.com/toddreifsteck/charter-webperf/2015draft/index.html

Todd: TODO: add remaining information, sort by priority.

Ilya: on deliverables: Performance Observer is part of Timeline. no need to call it out

"The working group will deliver updated versions of the following:"

[[

Timing control for script-based animations

An interoperable and efficient means for web page authors to write script-based animations where the user agent is in control of limiting the update rate of the animation.

]]

https://html.spec.whatwg.org/multipage/browsers.html#the-window-object

http://www.w3.org/TR/html51/browsers.html#the-window-object

Ilya: should we remove requestAnimationFrame from our list?
... let's have it as an open issue for now
... should we move that spec in a separate section, moving into the html spec, but we need to make sure it's done correctly

Todd: it may not make sense to give up stewardship
... so I'd keep in the charter

Ilya: ok, let's keep it in the charter and resolve the differences between the specs

Marcos: do we know why it's in the html spec?

Plh: I propose that we keep it separate for now. it doesn't look like the definition in html spec is complete. we'll need to talk to them

Ilya: Server Timing is missing
... add CPU and memory
... https://github.com/w3c/charter-webperf/pull/1

Yoav: not sure if it belongs to us or houdini

Ilya: visibility seems more like houdini but they're not aware of the problems

Yoav: should we do use cases then?

Todd: seems appropriate

Ilya: can we make it a goal for the group to draft use cases?

Plh: sounds good

Todd: ok

Ilya: emphasizing working with other groups

Plh: we should make sure we get reviews from webapps, tag, and webappsec
... in the deliverables section

<ToddReifsteck> FYI, here is an example of how CSS lists Deliverables: http://www.w3.org/2010/09/CSSWG/charter

Marcos: charters looks ok to me otherwise

http://www.w3.org/wiki/Web_Performance/Publications

Todd: I'll put a pointer to the dashboard then

Ilya: setImmediate?

Todd: I'll have data in 3 weeks

http://www.w3.org/Consortium/Legal/2015/copyright-software-and-document.html

Todd: it's more likely we get our charter more quickly
... without the new license

new draft for Performance Observer

Ilya: please have a look at the PR

https://github.com/w3c/performance-timeline/pull/10

Todd: we added various fields to navigation timing but didn't implement them
... should we keep them?

Ilya: for chrome, we are looking for a bunch of them, like workerStart
... it's a question of when
... some of the feedbacks is that it's not easy to find what's new

Todd: linkNegotiation, sizes, type, workerStart

Plh: they're listed in the status but I guess folks don't look at it

Ilya: we'll have to do some refactoring

<marcosc__> Bugzilla bug: https://bugzilla.mozilla.org/show_bug.cgi?id=1043083

Ilya: and be more precise on what has been implemented and where

Marcos: would be good to link to browser bugs

<marcosc__> https://w3c.github.io/manifest/

[[

Implementation status:

Gecko

Blink

]]

Tood: seems a good solution for us

<yoav> Sorry folks, but I gotta go. Another meeting coming up...

Plh: I wanted to adopt CSS conventions for our draft, eg performance-timeline, performance-timeline-2, performance-timeline-2,
