ccd63c3c19 net/http: non-keepalive connections close successfully
Connections did not close if Request.Close or Response.Close was true. This meant that if the user wanted the connection to close, or if the server requested it via "Connection: close", the connection would not be closed.

b42ebb6fbf runtime: fix TLS handling for netbsd
Set the TLS base using the _lwp_setprivate() syscall, instead of via
sysarch(). NetBSD tracks the pointer passed to _lwp_setprivate() and
restores this value when restoring mcontext. If sysarch() is used
directly, restoring an mcontext trashes the FS/GS value, resulting
in a segfault when we next try to access the TLS.

e393a8292e mime/multipart: fix handling of empty parts without CRLF before next part
Empty parts can be either of the form:

a) "--separator\r\n", header (w/ trailing 2xCRLF), \r\n "--separator"...
or
b) "--separator\r\n", header (w/ trailing 2xCRLF), "--separator"...

We never handled case b).  In fact the RFC seems kinda vague about
it, but browsers seem to do a), and App Engine's synthetic POST
bodies after blob uploads is of form b).

So handle them both, and add a bunch of tests.

(I can't promise these are the last fixes to multipart, especially
considering its history, but I'm growing increasingly confident at
least, and I've never submitted a multipart CL with known bugs
outstanding, including this time.)

deflateInflateStringTests checks that the compressed form of e.txt
is not 'too large'. I'm not exactly sure how these numbers were
originally calculated (they were introduced in codereview 5554066
"make lazy matching work"); perhaps krasin@golang.org can comment.
My change was to increase the first one (no compression) to a tight
bound, and multiply all the others by 10.

Benchcmp numbers for compress/flate and compress/lzw below. LZW's
window size of 4096 is less than 10k, so shows no significant change.
Flate's window size is 32768, between 10k and 100k, and so the .*1e5
and .*1e6 benchmarks show a dramatic drop, since the compressed forms
are no longer a trivial forward copy of 10k digits repeated over and
over, but should now be more representative of real world usage.

ffd0d02d09 compress/flate: benchmark some English text, not just the digits of e.
The testdata/e.txt input is repeated on the longer benchmarks, but the
length of that data is less than flate's window size, so the numbers are
essentially measuring the performance of a trivial compression. A follow-up
CL will add more data to testdata/e.txt.

32b85baae3 compress/testdata: remove Byte Order Mark from the Tom Sawyer data.
I'm not sure where the BOM came from, originally.
http://www.gutenberg.org/files/74/74.txt doesn't have it, although
a fresh download of that URL gives me "\r\n"s instead of plain "\n"s,
and the extra line "Character set encoding: ASCII". Maybe Project
Gutenberg has changed their server configuration since we added that
file to the Go repo.

Anyway, this change is just manually excising the BOM from the start
of the file, leaving pure ASCII.

dac4c3eee9 cmd/cgo, cmd/cc, cmd/ld: detect dynamic linker automatically
Some newer Linux distributions (Ubuntu ARM at least) use a new multiarch
directory organization, where dynamic linker is no longer in the hardcoded

For example, Ubuntu 12.04 ARM hardfloat places its dynamic linker at
/lib/arm-linux-gnueabihf/ld-linux.so.3

Ref: http://lackof.org/taggart/hacking/multiarch/

Also, to support Debian GNU/kFreeBSD as a FreeBSD variant, we need this capability, so it's part of issue 3533.

10838165d8 exp/locale/collate: fixed two bugs uncovered by regression tests.
The first bug was that tertiary ignorables had the same colElem as
implicit colElems, yielding unexpected results. The current encoding
ensures that a non-implicit colElem is never 0.  This fix uncovered
another bug of the trie that indexed incorrectly into the null block.
This was caused by an unfinished optimization that would avoid the
need to max out the most-significant bits of continuation bytes.
This bug was also present in the trie used in exp/norm and has been
fixed there as well. The appearence of the bug was rare, as the lower
blocks happened to be nearly nil.

4de15a5cda compress/flate: optimize history-copy decoding.
The forwardCopy function could be re-written in asm, and the copyHuff
method could probably be rolled into huffmanBlock and copyHist, but
I'm leaving those changes for future CLs.

f72c828c67 net: consolidate common socket functions
In resolving 3507, the fix had to be applied individually to
the four *Conn types, tcp, udp, rawip and unix, due to the
duplicate code in each Conn type.

This CL consolidates the common net.Conn methods that all four
*Conn types implement into a base conn type.

Pros:
* The fix for 3507 would have only needed to be applied to one
method. Further improvements, such as possibly removing the
c.fd != nil check in c.ok(), would benefit from this CL.
* Nearly 300 lines removed from the net package.
* The public interface and documentation are not changed.
* I think this is an excellent example of the power of embedding.

Cons:
* The net package is already distributed over many files, this
CL adds another place to look.
* The fix for 3507 was a total of 16 lines changed, this follow
up CL could be considered to be an overreaction as new Conn types
are unlikely to be added in the near future.

5694ebf057 net/http/httputil: Clean up ReverseProxy maxLatencyWriter goroutines.
When FlushInterval is specified on ReverseProxy, the ResponseWriter is
wrapped with a maxLatencyWriter that periodically flushes in a
goroutine. That goroutine was not being cleaned up at the end of the
request. This resulted in a panic when Flush() was being called on a
ResponseWriter that was closed.

The code was updated to always send the done message to the flushLoop()
goroutine after copying the body. Futhermore, the code was refactored to
allow the test to verify the maxLatencyWriter behavior.

9a6cef8bbf exp/html: more comprehensive tests
Currently, the html package only runs a limited subset of the tests
in the testdata directory. This tends to limit development of the
parser to fixing the bug that causes the first failing test.

This CL gives it the ability to run all the tests and produce a
log showing the status of each test. (It does it when tests are run with
'go test --update-logs') The status is listed as PASS, FAIL, or PARSE
(PARSE means that parsing produced the correct tree, but rendering and
re-parsing does not produce the same tree).

When 'go test' is run without --update-logs, it runs the tests marked
'PASS' in the logs (and the parsing portion of the tests marked 'PARSE').
Thus it will fail if there has been a regression since the last
time the logs were updated.

My goal for this CL is to allow develoment of the html package to
be less test-driven, while still having the advantages of regression
tests. In other words, one can work on any portion of the parser
and quickly see whether he is breaking things or improving them.

Current statistics of the tests:
$ grep ^PASS *.log|wc -l
        1017
$ grep ^PARSE *.log|wc -l
          46
$ grep ^FAIL *.log|wc -l

"The plan9 exec child handler does not manage
dup-ed fds from the parent correctly: when a
dup-ed file descriptor appears in the child's fd
list it is closed when first encountered and then
subsequent attempt to dup it later in Pass 2 fails,
resulting in 'fork/exec: fd out of range or not

2d0d3d8f9e text/template: catch unexported fields during parse
It's a common error to reference unexported field names in templates,
especially for newcomers. This catches the error at parse time rather than
execute time so the rare few who check errors will notice right away.

These were always an error, so the net behavior is unchanged.
Should break no existing code, just identify the error earlier.

7247dcab92 crypto/tls: update how we create testing scripts.
crypto/tls is tested, in part, by replaying recorded TLS connections
and checking that the bytes sent by the Go code haven't changed.

Previously we used GnuTLS's debug output and extracted the bytes of
the TLS connection using a Python script. That wasn't great, and I
think GnuTLS removed that level of debugging in a more current
release.

This change records the connection with Go code and adds a test for
ECDHE-AES clients generating using this method.

7056ec6bfd runtime: fix floating point exception on Plan 9
Change 5660047 moved an FLDCW instruction
that disables invalid operand traps into
runtime·asminit, which is called from
runtime·mstart. Thus, runtime·check is being
called prior to setting the appropriate control bits,
which on any QNaN comparison will cause Plan 9
to take an invalid operand trap. This change loads
the control bits (for Plan 9) prior to runtime·check.
Ideally, this should be done before the QNaN checks
on any system, but possibly other kernels simply
don't ever trap on invalid operands.

e530d6a1e0 6c, 6g, 6l: add MOVQL to make truncation explicit
Without an explicit signal for a truncation, copy propagation
will sometimes propagate a 32-bit truncation and end up
overwriting uses of the original 64-bit value.

The case that arose in practice is in C but I believe
that the same could plausibly happen in Go.
The main reason we didn't run into the same in Go
is that I (perhaps incorrectly?) drop MOVL AX, AX
during gins, so the truncation was never generated, so
it didn't confuse the optimizer.

Fixes #3488.

Assignment of a computed uint64 value to an

long long *f(void) { return 0; }
void g(int x, int y) {
        *f() = (long long)x | (long long)y<<32;
}

Before:

(x.c:3)	TEXT	g+0(SB),(gok(71))
...
(x.c:4)	ORL	AX,DX
(x.c:4)	ORL	CX,BX
(x.c:4)	CALL	,f+0(SB)
(x.c:4)	MOVL	DX,(AX)
(x.c:4)	MOVL	BX,4(AX)

After:
(x.c:3)	TEXT	g+0(SB),(gok(71))
(x.c:4)	CALL	,f+0(SB)
...
(x.c:4)	ORL	CX,BX
(x.c:4)	ORL	DX,BP

c9529e02c1 time: in Format give buffer an initial capacity
I have a small web server that simply sets several cookies
along with an expires header, and then returns.  In the
cpuprofile for a 200k request benchmark, time.Time.Format()
was showing up as 8.3% of cpu usage.  Giving the buffer an
inital capacity to avoid reallocs on append drops it down to
7.6%.
