      go/doc: make examples that depend on top-level decls playable · 11f1fab4
      Hiroshi Ioka authored 
      Currently, the following example cannot run in playground:

    func a() {
        fmt.Println("A")
    }

    func ExampleA() {
        a()
    }

This CL solves it.

      crypto/tls: add RSASSA-PSS support for handshake messages · 87867505
      Peter Wu authored 
      This adds support for RSASSA-PSS signatures in handshake messages as
required by TLS 1.3. Even if TLS 1.2 is negotiated, it must support PSS
when advertised in the Client Hello (this will be done later as the
testdata will change).

      os: when looping in RemoveAll, close and re-open directory · a6a69227
      Ian Lance Taylor authored 
      On some systems removing files can cause a directory to be re-shuffled,
so simply continuing to read files can cause us to miss some.
Close and re-open the directory when looping, to avoid that.

Read more files each time through the loop, to reduce the chance of
having to re-open.

      reflect: prevent additional StructOf embedded method cases · 83092a40
      Ian Lance Taylor authored 
      The current implementation does not generate wrappers for methods of
embedded non-interface types. We can only skip the wrapper if
kindDirectIface of the generated struct type matches kindDirectIface
of the embedded type. Panic if that is not the case.

It would be better to actually generate wrappers, but that can be done
later.

      net: make concurrent resolver lookups independent · 63a4acba
      Grégoire Delattre authored 
      The current resolver uses a global lookupGroup which merges LookupIPAddr
calls together for lookups for the same hostname if used concurrently.
As a result only one of the resolvers is actually used to perform the
DNS lookup but the result is shared by all the resolvers.

This commit limits the scope of the lookupGroup to the resolver itself
allowing each resolver to make its own requests without sharing the
result with other resolvers.

Fixes #22908

      Ian Lance Taylor authored 
      RFC 2045 doesn't permit non-ASCII bytes, but some systems send them
anyhow. With this change, we accept them. This does make it harder to
validate quotedprintable data, but on balance this seems like the best
approach given the existence of systems that generate invalid data.

      net: limit concurrent threads to limit on file descriptors · b7498450
      Ian Lance Taylor authored 
      At least on Darwin, if getaddrinfo can't open a file descriptor it
returns EAI_NONAME ("no such host") rather than a meaningful error.
Limit the number of concurrent getaddrinfo calls to the number of file
descriptors we can open, to make that meaningless error less likely.

We don't apply the same limit to Go lookups, because for that we will
return a meaningful "too many open files" error.

      Some headers, which are set or modified by the http library,
are not written to the standard http.Request.Header and are
not included as part of http.Response.Request.Header.

Exposing all headers alleviates this problem.

This is not a complete solution to 19761 since it does not have http/2 support.

      cmd/compile: fold offset into address on Wasm · 1d303a00
      Cherry Zhang authored 
      On Wasm, the offset was not folded into LoweredAddr, so it was
not rematerializeable. This led to the address-taken operation
in some cases generated too early, before the local variable
becoming live. The liveness code thinks the variable live when
the address is taken, then backs it up to live at function
entry, then complains about it, because nothing other than
arguments should be live on entry.

This CL folds the offset into the address operation, so it is
rematerializeable and so generated right before use, after the
variable actually becomes live.

It might be possible to relax the liveness code not to think a
variable live when its address being taken, but until the address
actually being used. But it would be quite complicated. As we're
late in Go 1.11 freeze, it would be better not to do it. Also,
I think the address operation is rematerializeable now on all
architectures, so this is probably less necessary.

This may also be a slight optimization, as the address+offset is
now rematerializeable, which can be generated on the Wasm stack,
without using any "registers" which are emulated by local
variables on Wasm. I don't know how to do benchmarks on Wasm. At
least, cmd/go binary size shrinks 9K.

Fixes #25966.
