Phrases like "returns whether or not the image is opaque" could be
describing what the function does (it always returns, regardless of

Even when the "or not" is missing, the phrasing is bizarre.

"There are only two hard problems in computer science:
cache invalidation, naming things, and off-by-one errors."
The HTTP server code already strips Expect: 100-continue on
requests, so httputil.ReverseProxy should be unaffected, but
some servers send unsolicited HTTP/1.1 100 Continue responses,
so we need to skip over them if they're seen to avoid getting
off-by-one on Transport requests/responses.
This does change the behavior of people who were using Client
or Transport directly and explicitly setting "Expect: 100-continue"
themselves, but it didn't work before anyway. Now instead of the
user code seeing a 100 response and then things blowing up, now
it basically works, except the Transport will still blast away
the full request body immediately. That's the part that needs

If a handler didn't consume all its Request.Body, child.go was
closing the socket while the host was still writing to it,
causing the child to send a RST and the host (at least nginx)
to send an empty response body.
Now, we tell the host we're done with the request/response
first, and then close our input pipe after consuming a bit of
it. Consuming the body fixes the problem, and flushing to the
host first to tell it that we're done increases the chance
that the host cuts off further data to us, meaning we won't
have much to consume.

Current code relies on the fact that fd's are automatically removed from epoll set when closed. However, it is not true. Underlying file description is removed from epoll set only when *all* fd's referring to it are closed.
There are 2 bad consequences:
1. Kernel delivers notifications on already closed fd's.
2. The following sequence of events leads to error:
- add fd1 to epoll
- dup fd1 = fd2
- close fd1 (not removed from epoll since we've dup'ed the fd)
- dup fd2 = fd1 (get the same fd as fd1)
- add fd1 to epoll = EEXIST
So, if fd can be potentially dup'ed of fork'ed, it's necessary to explicitly remove the fd from epoll set.

In a nutshell, if our HTTP client needs a TCP connection to a

kick off a dial and wait for that specific dial, we instead
kick off a dial and wait for either our own dial to finish, or
any other TCP connection to that same host to become
available.

Previously the HTTP client's (*Response).Body.Close would try
to keep reading until EOF, hoping to reuse the keep-alive HTTP
connection, but the EOF might never come, or it might take a
long time. Now we immediately close the TCP connection if we
haven't seen EOF.
This shifts the burden onto clients to read their whole response
bodies if they want the advantage of reusing TCP connections.
In the future maybe we could decide on heuristics to read some
number of bytes for some max amount of time before forcefully
closing, but I'd rather not for now.
Statistically, touching this code makes things regress, so I
wouldn't be surprised if this introduces new bugs, but all the
tests pass, and I think the code is simpler now too. Maybe.

The test suite for ReadResponse was not checking the error return on the io.Copy
on the body. This was masking two errors: the handling of chunked responses to
HEAD requests and the handling of Content-Length > 0 to HEAD.
The former manifested itself as an 'unexpected EOF' when doing the io.Copy
because a chunked reader was assigned but there were no chunks to read. The
latter cause (*http.Response).Write to report an error on HEAD requests
because it saw a Content-Length > 0 and expected a body.
There was also a missing \r\n in one chunked test that meant that the chunked
encoding was malformed. This does not appear to have been intentional.

reporting happens through the underlying file operation.
In Go code, we go through package os for file operations,

Functions for representing network connections as files
and vice versa, on Plan 9.
Representing network connections as files is not so
straight-forward, because a network connection on Plan 9
is represented by a host of files rather than a single
file descriptor (as is the case on UNIX). We use the
type system to distinguish between listeners and
connections, returning the control file in the former
case and the data file in the latter case.

It's accessed without mutex protection
in a different goroutine from the one that
sets it.
Also make sure that Client.Call after Client.Close
will reliably return ErrShutdown, and that clients
see ErrShutdown rather than io.EOF when appropriate.
Suggestions welcome for a way to reliably test
the mutex issue.

The data file should be opened when a Conn is first
established, rather than waiting for the first Read or
Write.
Upon Close, we now make sure to try to close both, the
ctl as well as data files and set both to nil, even in
the face of errors, instead of returning early.
The Accept call was not setting the remote address
of the connection properly. Now, we read the correct
file.
Make functions that establish Conn use newTCPConn
or newUDPConn.

This CL changes nothing to existing API behavior, just sets up
Zone in IPNet and IPAddr structures if possible.
Also does small simplification.
Update #4234.

On Linux point-to-point interface an IFA_ADDRESS attribute
represents a peer address. For a correct interface address
we should take an IFA_LOCAL attribute instead.
Fixes#4839.

If a test can be placed in the same package ("internal"), it is placed
there. This facilitates testing of package-private details. Because of
dependency cycles some packages cannot be tested by internal tests.

Subject Alternative Names in X.509 certificates may include IP
addresses. This change adds support for marshaling, unmarshaling and
verifying this form of SAN.
It also causes IP addresses to only be checked against IP SANs,
rather than against hostnames as was previously the case. This
reflects RFC 6125.
Fixes#4658.

It is too flaky. Tried to make it more reliable,
but that affects other tests (they run too long),
because we do unusual things here, like attempting
to connect to non-existing address and interrupt.

The test for issue 3590 causes an error to be printed to stderr when run (although the error is obscured during go test std). This is confusing for people who get breakage in the net package as the error is harmless and most likely unrelated to their build breakage.
Given the way the test works, by reaching into the guts of the netFD, I can't see a way to silence the error without adding a bunch of code to support the test, therefore I am suggesting the test be removed before Go 1.1 ships.
