[Tracking Requested - why for this release]:

Nicholas, so, this is a preference that will only turn on when Firefox 34 is in beta?  Is there anything in particular we should be aware of in QA for testing this - or just have a look at it when it goes to beta? Thanks!

I'm running the 20140805 (rev https://hg.mozilla.org/mozilla-central/rev/7f81be7db528 ) nightly, yet "network.http.spdy.enabled.http2draft" is still set to false ?

no - this pref is simply on.

We'll be tracking interop opportunities - right now the only thing to be aware of are general regressions.

I'm  not sure why you marked this for tracking.

That's one day too early. The newest nightly (20140806, rev 6cbdd4d523a7) is the one you want.

Backed out by request, for causing bug 1050063. Nightlies respun.

Here's the version that has been checked in, and must be checked in again...

Landed direct to m-c because it already landed just fine once except for the twitter issue:

So, for the record, this WILL make tonight's Nightly build.

thanks ;)

I feel like I'm in an on again off again relationship.

interestingly twitter has deployed a server side fix instead of rolling  back h2-14. Their implementation actually launched after this was enabled the first time. (perhaps before it hit the nightly build though - unsure on that.)

Comment 19

Release Note Request (optional, but appreciated)
[Why is this notable]: The next era in Web tech has begun. Seriously.
[Suggested wording]: Implemented HTTP/2 and APLN.
[Links (documentation, blog post, etc)]: :hurley might have a blog post?

I don't (yet), though I'm planning on writing one. Perhaps I should get on that :)

Comment 21

[Sylvestre Ledru [:Sylvestre]]

Florian, what is APLN? The thing that I found is this bug.

Nicholas, is this going to ship in 34? Thanks

alpn is a tls extension that allows negotiation of http/2.

> Nicholas, is this going to ship in 34? Thanks

http2-draft14 support will ship as part of 34. That's the same thing that IE announced in their developer preview this week.

Support for the final http/2 will follow when the IETF has decided the format is final. If that that turns out to be the same thing as http2-draft14 then we will probably just uplift the final "http2" label to channels that already have working http2-draft14 support. hth

Comment 23

[Sylvestre Ledru [:Sylvestre]]

OK. Thanks for the info.
So, since it is not a final standard, maybe we should write in the release note
Implementation of HTTP/2 (draft14) and APLN

Comment 24

[Florian Bender]

I guess my ni? is covered by Comment 22, then :)

Comment 25

[Sylvestre Ledru [:Sylvestre]]

Added to the release notes with "Implementation of HTTP/2 (draft14) and APLN" as wording.
A blog post or documentation would be appreciated!

typo - you want ALPN

Comment 27

[Sylvestre Ledru [:Sylvestre]]

Sorry. Fixed. thanks!

Comment 28

[[SV Manager] Florin Mezei, QA (:FlorinMezei)]

So looking at Firefox 34 Beta 10 (BuildID=20141117202603), I see the following preferences set by default:
network.http.spdy.enabled.http2draft = false
security.ssl.enable_alpn = true

Wasn't the http2 pref supposed to be true? Nicholas, am I missing something here?

Comment 29

[Patrick McManus [:mcmanus]]

see bug 1088910 - we held back http2draft after early_beta on 34 to give the standards process a little more breathing room and server operators a little more chance to mature their -14 implementations if they choose to offer them.

Comment 30

[[SV Manager] Florin Mezei, QA (:FlorinMezei)]

Thanks Patrick for clarifying this! Setting as "qe-verify-" since there doesn't seem to be anything for the QA team to do here.
