      http2/h2demo: fix the HTTP/1-vs-HTTP/2 demo after HSTS breakage · 65e2d4e1
      Brad Fitzpatrick authored 
      We were previously demoing HTTP/1 vs HTTP/2 loading performance using
http:// scheme (which uses HTTP/1 implicitly) on the http2.golang.org
domain for HTTP/1, and https://http2.golang.org for HTTP/2.

But then golang.org got into the HSTS preload list, forcing all
*.golang.org to only be HTTPS.

So now, rather than find a new base domain name, to compare against
HTTP/1 we instead use https://http1.golang.org/ and then use the SNI
name to determine whether we advertise "h2".

Also, some cleanup:

* remove launch.go; it's no longer used since we moved to kubernetes
* use a multi-stage Dockerfile rather than the hacky workarounds
  that used to be necessary to simulate multiple stages
* modernize the kubernetes deployment stuff to match how we do
  it elsewhere ("gcloud docker" is long deprecated too)
* update from Go 1.9 to Go 1.11 for the prod base

Fixes golang/go#30033

      publicsuffix: hold icann-ness until wildcards fully match · 927f9776
      Nigel Tao authored 
      Consider the "uberspace.de" domain. The relevant rules in the Public
Suffix List are "*.uberspace.de" (in the PRVIATE DOMAIN section) and
"de" (in the ICANN DOMAIN section).

The PublicSuffix function returns a string and a bool. Both before and
after this commit, the string returned is "de", which is correct
according to a literal interpretation of the formal algorithm. But the
bool returned, icann-ness, is false before and true after. The correct
answer is true, since the matching rule, "de", is in the ICANN DOMAIN
section of the PSL.

Before this commit, the two-stage match for "*.uberspace" set the icann
bit when matching the back part, "uberspace", before checking that the
front part, the "*" wildcard, also matched.

A couple more examples, for the "bd" and "ck" domains. The relevant
rules are "*.bd" and "*.ck", with no non-wildcard "bd" or "ck" rule.
Before this commit, the PublicSuffix function would return (icann ==
true), when the correct result is (icann == false), the same as for
"nosuchtld".

Benchmarks get worse, but correctness trumps performance. Future commits
may be able to recover some of the loss. In any case, in absolute terms,
15µs is still pretty fast.

      http2/hpack: track the beginning of a header block · 891ebc4b
      Michael Fraenkel authored 
      dynamic table size updates must occur at the beginning of the first
header block. The original fix, golang/go#25023, guaranteed it was at
the beginning of the very first block. The Close method implicitly
marked the end of the current header. We now document the Close behavior
and can track when we are at the beginning of the first block.

Updates golang/go#29187

      http2: revert Transport's strict interpretation of MAX_CONCURRENT_STREAMS · 351d144f
      Brad Fitzpatrick authored 
      And add the http2.Transport.StrictMaxConcurrentStreams bool knob to
behavior being reverted.

In CL 53250 for golang/go#13774 (for Go 1.10) we changed the HTTP/2
Transport's policy such that a server's advertisement of a
MAX_CONCURRENT_STREAMS value meant that it was a maximum for the
entire process, instead of just a single connection.

We thought that was a reasonable interpretation of the spec and
provided nice safety against slamming a server from a bunch of
goroutines doing concurrent requests, but it's been largely
unpopular (see golang/go#27044). It's also different behavior from
HTTP/1 and because you're usually not sure which protocol version
you're going to get, you need to limit your outbound HTTP requests
anyway in case you're hitting an HTTP/1 server.

And nowadays we have the Go 1.11 Transport.MaxConnsPerHost knob too
(CL 71272 for golang/go#13957). It doesn't yet work for HTTP/2, but it
will in either Go 1.12 or Go 1.13 (golang/go#27753)

After this is bundled into net/http's, the default HTTP client will
have this knob set false, restoring the old Go 1.9 behavior where new
TCP connections are created as necessary. Users wanting the strict
behavior and import golang.org/x/net/http2 themselves and make a
Transport with StrictMaxConcurrentStreams set to true. Or they can set
Transport.MaxConnsPerHost, once that works for HTTP/2.

Updates golang/go#27044 (fixes after bundle into std)
