      net/http: fix and normalize the [Server.][ListenAnd]Serve[TLS] docs · 7bebc6b7
      Filippo Valsorda authored 
      The only inaccurate part was the HTTP/2 caveat in Server.ServeTLS, which
only applies to the plain Serve variant.

The restriction implemented in shouldConfigureHTTP2ForServe is not on
the setupHTTP2_ServeTLS codepath because ServeTLS owns the tls.Listener,
so we fix it for the user instead of disabling HTTP/2.

Fixes #24607

      runtime: traceback from outermost libc call · fe68ab3b
      Keith Randall authored 
      If we're in a libc call and get a trap, don't try to traceback the libc call.
Start from the state we had at entry to libc.

If there are multiple libc calls outstanding, remember the outermost one.

Fixes #26393

      cmd/compile: set stricter inlining threshold in large functions · 5fc70b6f
      Keith Randall authored 
      If we're compiling a large function, be more picky about how big
the function we're inlining is.  If the function is >5000 nodes,
we lower the inlining threshold from a cost of 80 to 20.

Turns out reflect.Value's cost is exactly 80.  That's the function
at issue in #26546.

20 was chosen as a proxy for "inlined body is smaller than the call would be".
Simple functions still get inlined, like this one at cost 7:

func ifaceIndir(t *rtype) bool {
	return t.kind&kindDirectIface == 0
}

5000 nodes was chosen as the big function size.  Here are all the
5000+ node (~~1000+ lines) functions in the stdlib:

5187 cmd/internal/obj/arm (*ctxt5).asmout
6879 cmd/internal/obj/s390x (*ctxtz).asmout
6567 cmd/internal/obj/ppc64 (*ctxt9).asmout
9643 cmd/internal/obj/arm64 (*ctxt7).asmout
5042 cmd/internal/obj/x86 (*AsmBuf).doasm

6152 cmd/compile/internal/ssa rewriteValuePPC64_OpPPC64OR_60
6412 cmd/compile/internal/ssa rewriteValuePPC64_OpPPC64OR_70
6486 cmd/compile/internal/ssa rewriteValuePPC64_OpPPC64OR_80
6534 cmd/compile/internal/ssa rewriteValuePPC64_OpPPC64OR_90
6534 cmd/compile/internal/ssa rewriteValuePPC64_OpPPC64OR_100
6534 cmd/compile/internal/ssa rewriteValuePPC64_OpPPC64OR_110
6675 cmd/compile/internal/gc typecheck1
5433 cmd/compile/internal/gc walkexpr
14070 cmd/vendor/golang.org/x/arch/arm64/arm64asm decodeArg

There are a lot more smaller (~1000 node) functions in the stdlib.
The function in #26546 has 12477 nodes.

At some point it might be nice to have a better heuristic for "inlined
body is smaller than the call", a non-cliff way to scale down the cost
as the function gets bigger, doing cheaper inlined calls first, etc.
All that can wait for another release. I'd like to do this CL for
1.11.

Update #17566

      net/rpc: clarify requirements for connections and codecs · 08ab8204
      Dmitry Vyukov authored 
      1. Connections and codecs need to be partially safe for concurrent use.
   Namely, read side is serialized by one mutex,
   and writing side is serialized by another.
   Current comment says that they need to be fully thread-safe,
   which makes the default implementations (gobClientCodec/gobServerCodec)
   non-conforming.

2. Say that ServerCodec.Close can be called multiple times
   and must be idempotent. Server requires this and gobServerCodec
   accounts for this,  but the requirement is not documented.

      net/http: deflake TestRetryRequestsOnError · 416676f4
      Brad Fitzpatrick authored 
      There's a 50ms threshold in net/http.Transport that this test
sometimes hitting on slower devices. That was unrelated to what this
test was trying to test. So instead just t.Skip on RoundTrip errors
unless the failure was quick (under 25ms), in which case the error
must've been about something else. Our fast machines should catch
regressions there.

Fixes #25366
