Review charter feedback and proposed process updates


      [13] https://w3c.github.io/charter-webperf/

    Plh: I'll make it official tomorrow



    /TR/performance-timeline would be in sync with the github



    todd: should we have a branch in the repo that also contains
    that snapshot?

    Ilya: yes, snapshot with a branch seem reasonnable
    ... so the most recent would be gh-pages?

    plh: yes

    Resolved: Performance Timeline 2 can be published as a FPWD

    Resolved: User Timing 2 can be published as a FPWD

    Resolved: Server Tming can be published as a FPWD

    Resolved: Preload can be published as a FPWD

    /TR/performance-timeline -> /TR/performance-timeline-2


    Resolved: adopted the new versioning and branching

    Resolved: WDs should be automatically published


      [15] http://www.w3.org/TR/navigation-timing-2/

time origin & workerStart

    <igrigorik> [16]https://github.com/w3c/hr-time/pull/6

      [16] https://github.com/w3c/hr-time/pull/6

    Ilya: we should deprecate workerStart in favor of a translated
    time based approach

    Todd: didn't get feedback from Justin yet, makes sense from
    ... we should wait for Boris to give a +1 as well

    plh: you don't need to deprecate workerStart. it never made it
    into a REC. just removing it is fine.

attribute filtering


      [17] https://github.com/w3c/performance-timeline/pull/11

    Ilya: [summarizing the history].


    Todd: ok to merge

    Ilya: I'll merge and ping the list

revise "return copy"


      [19] https://github.com/w3c/performance-timeline/issues/20

    Ilya: Chrome and Firefox do not return a copy of the array
    ... IE does
    ... can we remove the "copy"? it's still ok to return a copy

    Todd: looks good to me

    <mpb> Do we need to change language on the Performance Observer
    interface too?



    Ilya: yes, perf observer shouldn't return a copy either

credentials in URLs


      [21] https://github.com/w3c/resource-timing/issues/7

    Todd: it's been suggested that exposing credentials in URLs
    through RT makes it easier to capture the credentials
    ... the move to Fetch will disallow this and fetch will speak
    to it

    Ilya: we can drop the credentials, but you won't get the same
    value for the url. and if you use different credentials, you
    won't be able to differentiate it
    ... I propose to close it as "wontfix"
    ... and let the browsers make their own decision (ie do as IE
    by disallowing that type of request)

    Resolved: wontfix


    plh: drop it?



    Ilya: we haven't been successful at implementing
    ... we could ressurect it in the future if we have access to
    the data.

    Resolved: drop linkNegotiationStart

Navigation Timing 2

    Todd: ALPN id / nextHopProtocol . has value and no plan for
    ... ditto for redirectCount
    ... should we do a snapshot of NT2?

    plh: pb is that only IE supports it on top of performance

    [discussion on the need to do snapshots of HRT2, PT2, and RT

    Ilya: open question related to nextHopProtocol into exposing
    too much networking information

    Todd: didn't think of that yet

    Ilya: redirectCount. was about making resource timing
    multi-fetch friendly
    ... if NT2 gets defined on top of RT, we won't need that

    Todd: also some concerns about security/privacy of that one

Call schedule for the summer

    Ilya: next one is 07/15
    ... then 08/12
