Per the curl man page, the http_proxy configuration can be
of the form:
[protocol://]<host>[:port]
And we had a test that <ip>:<port> worked, but if
the host began with a letter, url.Parse parsed the hostname
as the scheme instead, confusing ProxyFromEnvironment.

64bit atomics are broken on 32bit systems. This is issue 599.
linux/arm builders all broke with this change, I am concerned that the other 32bit builders are silently impacted.

RFC 2616: "The 204 response MUST NOT include a message-body,
and thus is always terminated by the first empty line after
the header fields."
Previously we'd trigger chunked encoding by default on
responses, and then when finishing the request we'd write the
chunk trailers, which counted as a message-body.

these are closed properly after test is over, otherwise

Update #4434.
The proposal attempts to reduce the number of places where fd,{r,w}deadline is checked and updated in preparation for issue 4434. In doing so the deadline logic is simplified by letting the pollster return errTimeout from netFD.Wait{Read,Write} as part of the wakeup logic.
The behaviour of setting n = 0 has been restored to match rev 2a55e349097f, which was the previous change to fd_unix.go before CL 6851096.

Thanks to Dustin Sallings for exposing the most frustrating
bug ever, and for providing repro cases (which formed the
basis of the new tests in this CL), and to Dave Cheney and
Dmitry Vyukov for help debugging and fixing.
This CL depends on submited pollster CLs ffd1e075c260 (Unix)
and 14b544194509 (Windows), as well as unsubmitted 6852085.
Some operating systems (OpenBSD, NetBSD, ?) may still require
more pollster work, fixing races (Issue 4434 and
http://goo.gl/JXB6W).
Tested on linux-amd64 and darwin-amd64, both with GOMAXPROCS 1
and 4 (all combinations of which previously failed differently)

If the a network read would block, and a packet arrived just before the timeout expired, then the number of bytes from the previous (blocking) read, -1, would be returned.
This change restores the previous logic, where n would be unconditionally set to 0 if err != nil, but was skipped due to a change in CL 6851096.
The test for this change is CL 6851061.

quicker than Linux)

The tests verify that deadlines are "persistent",
read/write deadlines do not interfere, can be reset,
read deadline can be set with both SetDeadline()
and SetReadDeadline(), etc.

Otherwise a fast sender or receiver can make sockets always
readable or writable, preventing deadline checks from ever
occuring.

Noticed this while closing tabs. Yesterday I thought I could
ignore this garbage and hope that a fix for issue 2205 handled
it, but I just realized that's the opposite case,
string->[]byte, whereas this is []byte->string. I'm having a
hard time convincing myself that an Issue 2205-style fix with
static analysis and faking a string header would be safe in
all cases without violating the memory model (callee assumes
frozen memory; are there non-racy ways it could keep being
modified?)

Fixes#4369.
Remove the check for fd.sysfd < 0, the first line of fd.accept() tests if the fd is open correctly and will handle the fd being closed during accept.

This is part 1 of a series of proposals to fix issue 4369.
In resolving issue 3507 it was decided not to nil out the inner conn.fd field to avoid a race. This implies the checks for fd == nil inside incref/decref are never true.
Removing this logic removes one source of errClosing error values, which affects issue 4373 and moves towards bradfitz's request that fd.accept() return io.EOF when closed concurrently.

This is a simplified version of earlier versions of this CL
and now only fixes obviously incorrect things, without
changing the locking on bodyEOFReader.

locking.

When a nil listener address is passed to some protocol specific
listen function, it will create an unnamed, unbound socket because
of the nil listener address. Other listener functions may return
invalid address error.
This CL allows to pass a nil listener address to all protocol
specific listen functions to fix above inconsistency. Also make it
possible to return a proper local socket address in case of a nil
listner address.
