      http2: fix over-aggressive ignoring of frames while in "go away" mode · 569280fa
      Brad Fitzpatrick authored 
      https://golang.org/cl/31727 made many of the Server Frame processors
ignore incoming frames if the connection was in shutdown mode.

The idea was that it's pointless to do work if we're about to hang up
on them in 250ms anyway for violating a protocol error.

But as of https://golang.org/cl/32412 (graceful shutdown) we can also
be in "go away" mode for ErrCodeNo, which just means to nicely tell
them to GOAWAY and because they did nothing wrong, we don't hang up in
250ms (the value of which gave the peer time to read the error before
the TCP close), but instead we keep the conn open until it's idle.

The combination of the two CLs made TestTransportAndServerSharedBodyRace_h2
flaky, since it was never seeing RST_STREAM on cancelation of requests,
and then Handlers would block forever.

Updates golang/go#17733 (fixes after bundle into std)

      webdav: add Context argument to FileSystem interface · 4bb47a10
      Daniel Theophanes authored 
      Currently there is no way to pass request scoped information from
the handler to the FileSytem interface. This can be important
to pass credentials or timeout parameters to the FileSystem
operations. Pipe context through the request from
http.Request.Context(). With pre-go1.7 use context.Background().

Custom FileSystem implementations will need to change, but it will
only require a new argument in each of the FileSystem methods.
The change will be trivial to update to.

Fixes golang/go#17658

      http2: initialize Server.IdleTimeout from http.Server as http1 does · b336a971
      Brad Fitzpatrick authored 
      This makes ConfigureServer initialize the http2 Server's IdleTimeout
from the http1 Server configuration, using the same rules as
IdleTimeout in Go 1.8: first use IdleTimeout if specified, else fall
back to the old ReadTimeout.

This changes it to be a loop instead.

This also fixes the "internal error: attempt to send frame on
half-closed-local stream" crash from golang/go#17627 because
wroteFrame set stateHalfClosedLocal temporarily while calling
resetStream which itself does a write in some cases. Prior to CL 31495
those writes were processed breadth-first. CL 31495 made the writes
generated from resetStream (like the window updates returning unused
flow-control) more aggressive and scheduled immediately. This loop
restores the old write scheduling.

Fixes golang/go#17627

      http2: optimize server frame writes · e7b14352
      Brad Fitzpatrick authored 
      Don't do async frame writes when the write is known to be small enough
to definitely fit in the write buffer and not cause a flush (which
might block). This avoids starting a new goroutine and doing a channel
send operation for many frame writes.

The headers frame is the main last one which might show some benefit
if there's a cheap enough way to conservatively calculate its size.
