net/http currently assumes that the response to a HEAD request
will always have a Content-Length header. This is incorrect.
RFC2616 says: "The HEAD method is identical to GET except that
the server MUST NOT return a message-body in the response. The
metainformation contained in the HTTP headers in response to a
HEAD request SHOULD be identical to the information sent in
response to a GET request. This method can be used for
obtaining metainformation about the entity implied by the
request without transferring the entity-body itself. This
method is often used for testing hypertext links for validity,
accessibility, and recent modification."
This means that three cases are possible: a Content-Length
header, a Transfer-Encoding header or neither. In the wild the
following sites exhibit these behaviours (curl -I):
HEAD on http://www.google.co.uk/ has Transfer-Encoding: chunked
HEAD on http://www.bbc.co.uk/ has Content-Length: 45247
HEAD on http://edition.cnn.com/ has neither header
This patch does not remove the ErrMissingContentLength error
for compatibility reasons, but it is no longer used.

This prevents the occasional issue when Mercurial screws up the locking
itself, and by moving the locking into this process we can use the
goroot for other things (such as automatically updating the builder
binary).
It also asks all builders to poll for new commits.

This function is absolutely critical for clients such as
exp/ssa, and too complex for clients to duplicate.
As with CL 7200046, gri expressed in the doc below [gophers
only] before going on leave that he intended to expose such a
predicate, though his wording suggests as an interface method
of Type rather than a standalone function. (My preference is
for binary methods to be standalone; see "On Binary Methods",
Kim Bruce, 1995). In any case if he wishes to move it that's
easily accommodated by clients.

On Windows, crypto/x509 passes through to Windows's CryptoAPI
to verify certificate chains. This method can't produce a
SystemRootsError, so make sure we always skip the test on
Windows.
This is needed because testVerify is called in both
TestGoVerify and TestSystemVerify on Windows - one is for
testing the Go verifier, the other one is for testing the
CryptoAPI verifier. The orignal CL tried to sidestep
this issue by setting systemSkip to true, but that only
affected TestSystemVerify.

further to how (I believe) it will end up being.
It is nicer to separate search from sorting functionality. Collation needs tables that
are not needed by search and vice-versa. The common functionality is separated out
in the Weigher interface. As this interface is very low-level, it will be moved to
a sub package (colltab) in a next CL.
The types that will move to this package are Weigher, Elem, and Level. The addition
of Elem allows for removing some of the duplicate code between collate and collate/build.
This CL also introduces some stubs for a higher-level API for options. The default
proposed options are quite complex and require the user to have a decent understanding
of Unicode collation. The new options hide a lot of the complexity.

Fixes the fork-exec/wait race condition for ForkExec
as well, by making it use startProcess. This makes the
comment for StartProcess consistent as well.
Further, the passing of Waitmsg data in startProcess
and WaitProcess is protected against possible forks
from outside of ForkExec and StartProcess, which might
cause interference with the Await call.

Using bytes.Buffer:

I also tried making a version of escape() that writes directly to the
bytes.Buffer, but it only saved 1 alloc/op and increased CPU time by
about 10%. Didn't seem worth the extra code path.

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.

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.
