      crypto/ecdsa: correct code comment. · 99841957
      Adam Langley authored 
      The code comment mixed up max and min. In this case, min is correct
because this entropy is only used to make the signature scheme
probabilistic. (I.e. if it were fixed then the scheme would still be
secure except that key.Sign(foo) would always give the same result for a
fixed key and foo.)

For this purpose, 256-bits is plenty.

Fixes #16819.

      crypto/x509: return better error when a certificate contains no names. · 49aa1d79
      Adam Langley authored 
      Currently, if a certificate contains no names (that we parsed),
verification will return the confusing error:
    x509: certificate is valid for , not example.com.

This change improves the error for that situation.

Fixes #16834.

      crypto/x509: fix name constraints handling. · e4dafa32
      Adam Langley authored 
      This change brings the behaviour of X.509 name constraints into line
with NSS[1]. In this area, the behavior specified by the RFC and by NIST
differs and this code follows the NIST behaviour.

[1] https://github.com/servo/nss/blob/master/lib/certdb/genname.c

Fixes #16347, fixes #14833.

      cmd/compile: improve error message for wrong number of arguments to return · 2d573eee
      Emmanuel Odeke authored 
      Fixes #4215.
Fixes #6750.

Improves the error message for wrong number of arguments by comparing
the signature of the return call site arguments, versus the function's
expected return arguments.

In this CL, the signature representation of:
+ ideal numbers(TIDEAL) ie float*, complex*, rune, int is
"number" instead of "untyped number".
+ idealstring is "string" instead of "untyped string".
+ idealbool is "bool" instead of "untyped bool".

However, the representation of other types remains as the compiler
would produce.

* Example 1(in the error messages, if all lines were printed):
$ cat main.go && go run main.go
package main

func foo() (int, int) {
  return 2.3
}

func foo2() {
  return int(2), 2
}

func foo3(v int) (a, b, c, d int) {
  if v >= 5 {
    return 1
  }
  return 2, 3
}

func foo4(name string) (string, int) {
  switch name {
  case "cow":
    return "moo"
  case "dog":
    return "dog", 10, true
  case "fish":
    return ""
  default:
    return "lizard", 10
  }
}

type S int
type T string
type U float64

func foo5() (S, T, U) {
  if false {
    return ""
  } else {
    ptr := new(T)
    return ptr
  }
  return new(S), 12.34, 1 + 0i, 'r', true
}

func foo6() (T, string) {
  return "T"
}

./issue4215.go:42: too many arguments to return, got (*S, number, number, number, bool) want (S, T, U)
./issue4215.go:46: not enough arguments to return, got (string) want (T, string)
./issue4215.go:46: too many errors

* Example 2:
$ cat 6750.go && go run 6750.go
package main

import "fmt"

func printmany(nums ...int) {
  for i, n := range nums {
    fmt.Printf("%d: %d\n", i, n)
  }
  fmt.Printf("\n")
}

func main() {
  printmany(1, 2, 3)
  printmany([]int{1, 2, 3}...)
  printmany(1, "abc", []int{2, 3}...)
}
./issue6750.go:15: too many arguments in call to printmany, got (number, string, []int) want (...int)
