Unfortunately Oracle Solaris does not have TCP_KEEPIDLE and
TCP_KEEPINTVL. TCP_KEEPIDLE is equivalent to TCP_KEEPALIVE_THRESHOLD,
but TCP_KEEPINTVL does not have a direct equivalent, so we don't set
TCP_KEEPINTVL any more.
Old Darwin versions also lack TCP_KEEPINTVL, but the code tries to set
it anyway so that it works on newer versions. We can't do that because
Oracle might assign the number illumos uses for TCP_KEEPINTVL to a
constant with a different meaning.
Unfortunately there's nothing we can do if we want to support both
illumos and Oracle Solaris with the same GOOS.

Remove the "netaddr" type, which ambiguously represented either one

multiple addresses are supported.
The "first" method returns the first address matching some condition
(e.g. "is it IPv4?"), primarily to support legacy code that can't handle
multiple addresses.
The "partition" method splits an addrList into two categories, as
defined by some strategy function. This is useful for implementing
Happy Eyeballs, and similar two-channel algorithms.
Finally, internetAddrList (formerly resolveInternetAddr) no longer
mangles the ordering defined by getaddrinfo. In the future, this may

There was a logical race in Transport.RoundTrip where a roundtrip with
a pending response would race with the channel for the connection
closing. This usually happened for responses with connection: close
and no body.
We handled this race by reading the close channel, setting a timer
for 100ms and if no response was returned before then, we would then
return an error.
This put a lower bound on how fast a connection could fail. We couldn't
fail a request faster than 100ms.
Reordering the channel operations gets rid of the logical race. If
the readLoop causes the connection to be closed, it would have put
its response into the return channel already and we can fetch it with
a non-blocking receive.

directly. But once you're done with the Peek'd data, you can't get rid

Both Read and io.CopyN(ioutil.Discard, bufReader, N) are relatively

Before this CL, if the system resolver does a very slow DNS
lookup for a particular host, all subsequent requests for that
host will hang waiting for that lookup to complete. That is
more or less expected when Dial is called with no deadline.
When Dial has a deadline, though, we can accumulate a large
number of goroutines waiting for that slow DNS lookup. Try to
avoid this problem by restarting the DNS lookup when it is
redone after a deadline is passed.
This CL also avoids creating an extra goroutine purely to
handle the deadline.
No test because we would have to simulate a slow DNS lookup

The http package by default adds "Accept-Encoding: gzip" to outgoing
requests, unless it's a bad idea, or the user requested otherwise.
Only when the http package adds its own implicit Accept-Encoding header
does the http package also transparently un-gzip the response.
If the user requested part of a document (e.g. bytes 40 to 50), it appears
that Github/Varnish send:
range(gzip(content), 40, 50)
And not:
gzip(range(content, 40, 50))
The RFC 2616 set of replacements (with the purpose of
clarifying ambiguities since 1999) has an RFC about Range
requests (http://tools.ietf.org/html/rfc7233) but does not
mention the interaction with encodings.
Regardless of whether range(gzip(content)) or gzip(range(content)) is
correct, this change prevents the Go package from asking for gzip
in requests if we're also asking for Range, avoiding the issue.
If the user cared, they can do it themselves. But Go transparently
un-gzipping a fragment of gzip is never useful.

This avoids a pop-up box on OS X and it avoids
a test failure if something is using 5555.
I apologize for not noticing this during the review.

http.Client calls URL.String() to fill in the Referer header, which may
contain authentication info. This patch removes authentication info from
the Referer header without introducing any API changes.
A new test for net/http is also provided.
This is the polished version of Alberto García Hierro's
https://golang.org/cl/9766046/
It should handle https Referer right.

The nicest solution would be to buffer the message and only write
it if it encodes correctly, but that adds considerable memory and
CPU overhead for a very rare condition. Instead, we just shut
down the connection if this happens.

Bodies larger than 8KB (the default bufio reader size) weren't
being dumped. Force a read of the body so they're teed into
the response buffer.

See comment 4 of https://code.google.com/p/go/issues/detail?id=8483#c4:
"So if a user creates a http.Client, issues a bunch of
requests and then wants to shutdown it and all opened connections;
what is she intended to do? The report suggests that just waiting for
all pending requests and calling CloseIdleConnections won't do, as
there can be new racing connections. Obviously she can't do what
you've done in the test, as it uses the unexported function. If this
happens periodically, it can lead to serious resource leaks (the
transport is also preserved alive). Am I missing something?"
This CL tracks the user's intention to close all idle
connections (CloseIdleConnections sets it true; and making a
new request sets it false). If a pending dial finishes and
nobody wants it, before it's retained for a future caller, the
"wantIdle" bool is checked and it's closed if the user has
called CloseIdleConnections without a later call to make a new
request.

Not sure why they used empty.s and all these other
packages were special cased in cmd/go instead.
Add them to the list.
This avoids problems with net .s files being compiled
with gcc in cgo mode and gcc not supporting // comments
on ARM.
Not a problem with bytes, but be consistent.
The last change fixed the ARM build but broke the Windows build.
Maybe *this* will make everyone happy. Sigh.

Those C files would have been compiled with 6c.
It's close to impossible to use C correctly anymore,
and the C compilers are going away eventually.

The previous implementation used per-socket TCP keepalive options
wrong. For example, it used another level socket option to control
TCP and it didn't use TCP_KEEPINTVL option when possible.
