Parse("file:///foo") previously returned a URL with Scheme "file"
and Path "///foo". Now it returns a URL with Path "/foo",
such that
&URL{Scheme: "file", Path: "/foo"}.String() == "file:///foo"
This means that parsing and stringifying the URL "file:/foo"
returns "file:///foo", technically a regression but one that only
affects a corner case.
Fixes#4189.

This proposal adds two methods to *testing.T, Skip(string) and Skipf(format, args...). The intent is to replace the existing log and return idiom which currently has 97 cases in the standard library. A simple example of Skip would be:
func TestSomethingLong(t *testing.T) {
if testing.Short() {
t.Skip("skipping test in short mode.")
// not reached
}
... time consuming work
}
Additionally tests can be skipped anywhere a *testing.T is present. An example adapted from the go.crypto/ssh/test package would be:
// setup performs some before test action and returns a func()
// which should be defered by the caller for cleanup.
func setup(t *testing.T) func() {
...
cmd := exec.Command("sshd", "-f", configfile, "-i")
if err := cmd.Run(); err != nil {
t.Skipf("could not execute mock ssh server: %v", err)
}
...
return func() {
// stop subprocess and cleanup
}
}
func TestDialMockServer(t *testing.T) {
cleanup := setup(t)
defer cleanup()
...
}
In verbose mode tests that are skipped are now reported as a SKIP, rather than PASS.

Go 1.0 behavior was to create an UnmarshalFieldError when a json value name matched an unexported field name. This error will no longer be created and the field will be skipped instead.

Previously, Go TLS servers always took the client's preferences into
account when selecting a ciphersuite. This change adds the option of
using the server's preferences, which can be expressed by setting
tls.Config.CipherSuites.
This mirrors Apache's SSLHonorCipherOrder directive.

The FmtLong flag should only be used with the %D verb
when printing an ATEXT Prog. It was erroneously used
for every Prog except ADATA. This caused a preponderance
of exclamation points, "!!", in the assembly listings.

very similar. Now the real differences are easily spotted

On Plan 9, only the parent of a given process can enter its wait
queue. When a Go program tries to fork-exec a child process
and subsequently waits for it to finish, the goroutines doing
these two tasks do not necessarily tie themselves to the same
(or any single) OS thread. In the case that the fork and the wait
system calls happen on different OS threads (say, due to a
goroutine being rescheduled somewhere along the way), the
wait() will either return an error or end up waiting for a
completely different child than was intended.
This change forces the fork and wait syscalls to happen in the
same goroutine and ties that goroutine to its OS thread until
the child exits. The PID of the child is recorded upon fork and
exit, and de-queued once the child's wait message has been read.
The Wait API, then, is translated into a synthetic implementation
that simply waits for the requested PID to show up in the queue
and then reads the associated stats.
