0355a71751 exp/locale/collate: Add maketables tool and generated tables.
Also set maxContractLen automatically.
Note that the table size is much bigger than it needs to be.
Optimization is best done, though, when the language specific
tables are added.

738e77aa4f compress/testdata: change {e,pi}.txt from 10k to 100k digits.
These files change from exactly 10003 bytes long to 100003: a digit,
a '.', 100k digits, and a '\n'.

The magic constants in compress/flate/deflate_test.go change since
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
path in our linker.
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.

"MOVW.W R4, -4(SP)" should really be "MOVW.W R4, -4(R13)",

This makes it possible to inline the prefetch of upcoming
memory addresses during garbage collection, instead of
needing to flush registers, make a function call, and
reload registers.  On garbage collection-heavy workloads,
this results in a 5% speedup.

Fixes #3493.

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.

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.

dde8358a1c exp/html: adjust inTableIM to match spec
Don't foster-parent text nodes that consist only of whitespace.
(I implemented this entirely in inTableIM instead of creating an

to combine character tokens into a string, which our tokenizer does
already.)

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

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:4)	CALL	,f+0(SB)
(x.c:4)	MOVL	DX,(AX)
(x.c:4)	MOVL	BX,4(AX)

After:

(x.c:4)	CALL	,f+0(SB)
...
(x.c:4)	ORL	CX,BX

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%.

22690e6621 crypto/rsa: only enforce that de ≡ 1 mod |(ℤ/nℤ)*| in order to load private keys generated by GnuTLS.
Previously we checked that de ≡ 1 mod φ(n). Since φ(n) is a multiple
of |(ℤ/nℤ)*|, this encompassed the new check, but it was too strict as
keys generated by GnuTLS would be rejected when gcd(p-1,q-1)≠1.

(Also updated the error strings in crypto/rsa to contain the package name, which some were missing.)

5eb007dede runtime: work around false negative in deadlock detection
Not a complete fix for issue 3342, but fixes the trivial case.
There may still be a race in the instants before and after
a scavenger-induced garbage collection.

Intended to be "obviously safe": a call to runtime·gosched
before main.main is no different than a call to runtime.Gosched
at the beginning of main.main, and it is (or had better be)
safe to call runtime.Gosched at any point during main.

Update #3342.

9d7076b178 cmd/go: respect $GOBIN always
Another attempt at https://golang.org/cl/5754088.

Before, we only consulted $GOBIN for source code
found in $GOROOT, but that's confusing to explain
and less useful.  The new behavior lets users set
GOBIN=$HOME/bin and have all go-compiled binaries
installed there.

Tested a few cases in test.bash.

Ran all.bash with and without $GOBIN and it works.
Even so, I expect it to break the builders,
like it did last time, we can debug from there.

Fixes #3269 (again).
Fixes #3396.
Fixes #3397.

671862747e go/build: fix import check
When we find a package in DIR/src/foo, we only let it
be known as foo if there is no other foo in an earlier
GOPATH directory or the GOROOT directory.
The GOROOT check was looking in GOROOT/src/foo
instead of GOROOT/src/pkg/foo, which meant that
the import paths "lib9", "libbio", "libmach", and so
on were unavailable, and the import paths "math",
"errors", and so on were available.  Correct this.

Fixes #3390.

6b0929505b cmd/go: fix two bugs
Issue 3207 was caused by setting GOPATH=GOROOT.
This is a common mistake, so diagnose it at command start
and also correct the bug that it caused in get (downloading
to GOROOT/src/foo instead of GOROOT/src/pkg/foo).

Issue 3268 was caused by recognizing 'packages' that
had installed binaries but no source.  This behavior is not
documented and causes trouble, so remove it.  We can
revisit the concept of binary-only packages after Go 1.

Fixes #3207.
Fixes #3268.

1f6fc949f6 sysycall: remove creds_linux_test.go
It is unprecedented to add tests to package syscall, especially
system-specific ones. Not a policy worth changing right before Go 1
is cut.

The sole existing test, passfd_test.go, contains the line
        // +build linux darwin probablyfreebsd probablyopenbsd
which argues that this is not a subject to be undertaking likely.
Note that passfd_test.go also went in just now. It's the only test
in syscall.

Deleting for now, will reconsider after Go 1.

cmd/go: respect $GOBIN always

Before, we only consulted $GOBIN for source code
found in $GOROOT, but that's confusing to explain
and less useful.  The new behavior lets users set
GOBIN=$HOME/bin and have all go-compiled binaries
installed there.

Fixes #3269.

c3954dd5da database/sql: ensure Stmts are correctly closed.
To make sure that there is no resource leak,
I suggest to fix the 'fakedb' driver such as it fails when any
Stmt is not closed.
First, add a check in fakeConn.Close().
Then, fix all missing Stmt.Close()/Rows.Close().
I am not sure that the strategy choose in fakeConn.Prepare/prepare* is ok.
The weak point in this patch is the change in Tx.Query:
  - Tests pass without this change,
  - I found it by manually analyzing the code,
  - I just try to make Tx.Query look like DB.Query.

Thanks to Gwenael Treguier for the failing test.

on most systems) so that the program counter will
tell us which system call is unhappy.

f3c39d8f2b go/parser: avoid endless loop in case of internal error
Factored the error synchronization code into two functions
syncStmt and syncDecl. Because they may return w/o advancing
the scanner, there is potential for endless loops across
multiple parse functions; typically caused by an incorrect
token list in these functions (e.g., adding token.ELSE to
syncStmt will cause the parser to go into an endless loop
for test/syntax/semi7.go without this mechanism). This would
indicate a compiler bug, exposed only in an error situation
for very specific source files. Added a mechanism to force
scanner advance if an endless loop is detected. As a result,
error recovery will be less good in those cases, but the parser
reported a source error already and at least doesn't get stuck.

a324a5ac20 crypto/x509: new home for root fetchers; build chains using Windows API
This moves the various CA root fetchers from crypto/tls into crypto/x509.

The move was brought about by issue 2997. Windows doesn't ship with all
its root certificates, but will instead download them as-needed when using
CryptoAPI for certificate verification.

This CL changes crypto/x509 to verify a certificate using the system root
CAs when VerifyOptions.RootCAs == nil. On Windows, this verification is
now implemented using Windows's CryptoAPI. All other root fetchers are
unchanged, and still use Go's own verification code.

The CL also fixes the hostname matching logic in crypto/tls/tls.go, in
order to be able to test whether hostname mismatches are honored by the
Windows verification code.

The move to crypto/x509 also allows other packages to use the OS-provided
root certificates, instead of hiding them inside the crypto/tls package.

Fixes #2997.

a385f38dfa net: delete usableLocalPort from test
The old way to find a port was to listen :0 and then
look at what port it picked, close the listener, and then
immediately try to listen on that port.

On some Windows 7 machines that sequence fails at
the second listen, because the first one is still lingering
in the TCP/IP stack somewhere.  (Ironically, most of these
are used in tests of a "second listen", which in this case
ends up being the third listen.)

Instead of this race, just return the listener from the
function, replacing usableLocalPort+Listen with
usableListenPort.

932c8ddba1 cmd/go: allow go get with arbitrary URLs
This CL permits using arbitrary, non-VCS-qualified URLs as
aliases for fully VCS-qualified and/or well-known code hosting
sites.

Example 1) A VCS-qualified URL can now be shorter.

Before:
$ go get camlistore.org/r/p/camlistore.git/pkg/blobref
After:
$ go get camlistore.org/pkg/blobref

Example 2) A custom domain can be used as the import,
referencing a well-known code hosting site.

Before:
$ go get github.com/bradfitz/sonden
After:
$ go get bradfitz.com/pkg/sonden

The mechanism used is a <meta> tag in the HTML document
retrieved from fetching:

    https://<import>?go-get=1  (preferred)
    http://<import>?go-get=1   (fallback)

The meta tag should look like:

<meta name="go-import" content="import-alias-prefix vcs full-repo-root">

The full-repo-root must be a full URL root to a repository containing
a scheme and *not* containing a ".vcs" qualifier.

The vcs is one of "git", "hg", "svn", etc.

The import-alias-prefix must be a prefix or exact match of the
package being fetched with "go get".

If there are multiple meta tags, only the one with a prefix
matching the import path is used. It is an error if multiple
go-import values match the import prefix.

If the import-alias-prefix is not an exact match for the import,
another HTTP fetch is performed, at the declared root (which does
*not* need to be the domain's root).

For example, assuming that "camlistore.org/pkg/blobref" declares
in its HTML head:

<meta name="go-import" content="camlistore.org git https://camlistore.org/r/p/camlistore" />

... then:

$ go get camlistore.org/pkg/blobref

... looks at the following URLs:

   https://camlistore.org/pkg/blobref?go-get=1
   http://camlistore.org/pkg/blobref?go-get=1
   https://camlistore.org/?go-get=1
   http://camlistore.org/?go-get=1

Ultimately it finds, at the root (camlistore.org/), the same go-import:

<meta name="go-import" content="camlistore.org git https://camlistore.org/r/p/camlistore" />

... and proceeds to trust it, checking out git //camlistore.org/r/p/camlistore at
the import path of "camlistore.org" on disk.

Fixes #3099

5e41fe0e45 build: use run.go for running tests
Also, tweak run.go to use no more than 2x the
number of CPUs, and only one on ARM.

53.85u 13.33s 53.69r 	 ./run
50.68u 12.13s 18.85r 	 go run run.go

Fixes #2833.

The dependency was there only to pull in two constants.

6e211225d7 syscall: fix mkall.sh, mksyscall_linux.pl, and regen for Linux/ARM
CL 3075041 says ARM is not little-endian, but my test suggests otherwise.
My test program is:

    package main
    import ("fmt"; "syscall"; "os")
    func main() {
       err := syscall.Fallocate(1, 1/*FALLOC_FL_KEEP_SIZE*/, 0, int64(40960));
       fmt.Fprintln(os.Stderr, err)
    }

Without this CL, ./test > testfile will show: file too large; and strace shows:
    fallocate(1, 01, 0, 175921860444160)    = -1 EFBIG (File too large)
With this CL, ./test > testfile will show: <nil>; and strace shows:
    fallocate(1, 01, 0, 40960)              = 0

Quoting rsc:
"[It turns out that] ARM syscall ABI requires 64-bit arguments to use an
(even, odd) register pair, not an (odd, even) pair. Switching to "big-endian"
worked because it ended up using the high 32-bits (always zero in the tests
we had) as the padding word, because the 64-bit argument was the last one,
and because we fill in zeros for the rest of the system call arguments, up to
six. So it happened to work."

I updated mksyscall_linux.pl to accommodate the register pair ABI requirement,
and removed all hand-tweaked syscall routines in favor of the auto-generated
ones. These including: Ftruncate, Truncate, Pread and Pwrite.

Some recent Linux/ARM distributions do not bundle kernel asm headers,
so instead we always get latest asm/unistd.h from git.kernel.org (just like
what we do for FreeBSD).
