18aa55c169 exp/locale/collate: first changes that introduce implementation of tailorings:
- Elements in the array are now sorted as a linked list.  This makes it easier to
  apply tailorings.
- Added code to sort entries by collation elements.
- Added logical reset points.  This is used for tailoring relative to certain
  properties, rather than characters.

NOTE: all code for type entry should now be in order.go.  To keep the diffs for
this CL reasonable, though, the existing code is left in builder.go.  I'll move
this in a separate CL.

dd79b330c9 syscall: add PtraceSyscall(pid int, signal int)
Fixes #3525.

PTRACE_SYSCALL behaves like PTRACE_CONT and can deliver
a signal to the process. Ideally PtraceSingleStep should
support the signal argument, but its interface is frozen
by Go1.

020c6558d9 runtime/pprof: restore articles in type doc comments
Reverts part of CL 6460082.

If a doc comment describes a type by explaining the
meaning of one instance of the type, a leading article
is fine and makes the text less awkward.

Compare:
// A dog is a kind of animal.
// Dog is a kind of animal.

de13e8dccd text/template: make spaces significant
Other than catching an error case that was missed before, this
CL introduces no changes to the template language or API.

For simplicity, templates use spaces as argument separators.
This means that spaces are significant: .x .y is not the same as .x.y.
In the existing code, these cases are discriminated by the lexer,
but that means for instance that (a b).x cannot be distinguished
from (a b) .x, which is lousy. Although that syntax is not
supported yet, we want to support it and this CL is a necessary
step.

This CL emits a "space" token (actually a run of spaces) from
the lexer so the parser can discriminate these cases. It therefore
fixes a couple of undisclosed bugs ("hi".x is now an error) but
doesn't otherwise change the language. Later CLs will amend
the grammar to make .X a proper operator.

There is one unpleasantness: With space a token, three-token
lookahead is now required when parsing variable declarations
to discriminate them from plain variable references. Otherwise
the change isn't bad.

The CL also moves the debugging print code out of the lexer
into the test, which is the only place it's needed or useful.

Step towards resolving issue 3999.
It still remains to move field chaining out of the lexer
and into the parser and make field access an operator.

f8d4bb884f net/http/httputil: fix race in DumpRequestOut
Fixes #3892.

Swapping the order of the writers inside the MultiWriter ensures
the request will be written to buf before http.ReadRequest completes.

The fencedBuffer is not required to make the test pass on
any machine that I have access too, but as the buf is shared
across goroutines, I think it is necessary for correctness.

79473d6b1c runtime: use netbsd signal ABI v2
Use version 2 of the NetBSD signal ABI - both version 2 and version 3
are supported by the kernel, with near identical behaviour. However,
the netbsd32 compat code does not allow version 3 to be used, which
prevents Go netbsd/386 binaries from running in compat mode on a
NetBSD amd64 kernel. Switch to version 2 of the ABI, which is the
same version currently used by NetBSD's libc.

cc842c738e text/template: allow grouping of pipelines using parentheses
Based on work by Russ Cox. From his CL:

        This is generally useful but especially helpful when trying
        to use the built-in boolean operators.  It lets you write:

        {{if not (f 1)}} foo {{end}}
        {{if and (f 1) (g 2)}} bar {{end}}
        {{if or (f 1) (g 2)}} quux {{end}}

        instead of

        {{if f 1 | not}} foo {{end}}
        {{if f 1}}{{if g 2}} bar {{end}}{{end}}
        {{$do := 0}}{{if f 1}}{{$do := 1}}{{else if g 2}}{{$do := 1}}{{end}}{{if $do}} quux {{end}}

The result can be a bit LISPy but the benefit in expressiveness and readability
for such a small change justifies it.

I believe no changes are required to html/template.

Fixes #3276.

c61a185f35 exp/locale/collate: add code to ignore tests with (unpaired) surrogates.
In the regtest data, surrogates are assigned primary weights based on
the surrogate code point value.  Go now converts surrogates to FFFD, however,
meaning that the primary weight is based on this code point instead.
This change drops tests with surrogates and lets the tests pass.

37b40dab51 database/sql: stop reuse of bad connections
The second parameter for sql.putConn() (err) is always nil. As a result bad
connections are reused, even if the driver returns an driver.ErrBadConn.
Unsing a pointer to err instead achievs the desired behavior.
See http://code.google.com/p/go/issues/detail?id=3777 for more details.

NOTE: there is no test for this, but 1) the code has now the same

tested and 2) Builder verifies the generated table so bugs in this

the locale-specific tables are all based on a CLDR root table.

27cb1cbb2e exp/html: skip render and reparse on more tests that build badly-formed parse trees
All of the remaining tests that had as status of PARSE rather than PASS had
good reasons for not passing the render-and-reparse step: the correct parse tree is
badly formed, so when it is rendered out as HTML, the result doesn't parse into the
same tree. So add them to the list of tests where that step is skipped.

Also, I discovered that it is possible to end up with HTML elements (not just text)
inside a raw text element through reparenting. So change the rendering routines to
handle that situation as sensibly as possible (which still isn't very sensible, but
this is HTML5).

a108369c83 syscall: return EINVAL when string arguments have NUL characters
Since NUL usually terminates strings in underlying syscalls, allowing
it when converting string arguments is a security risk, especially
when dealing with filenames. For example, a program might reason that
filename like "/root/..\x00/" is a subdirectory or "/root/" and allow
access to it, while underlying syscall will treat "\x00" as an end of
that string and the actual filename will be "/root/..", which might
be unexpected. Returning EINVAL when string arguments have NUL in
them makes sure this attack vector is unusable.

89d40b911c exp/locale/collate: changed API of Builder to be more convenient
for dealing with CLDR files:
- Add now taxes a list of indexes of colelems that are variables. Checking and
  handling is now done by the Builder.  VariableTop is now also properly generated
  using the Build method.
- Introduced separate Builder, called Tailoring, for creating tailorings of root
  table.  This clearly separates the functionality for building a table based on
  weights (the allkeys* files) versus tables based on LDML XML files.
- Tailorings are now added by two calls instead of one: SetAnchor and Insert.
  This more closely reflects the structure of LDML side and simplifies the
  implementation of both the client and library side.  It also preserves
  some information that is otherwise hard to recover for the Builder.
- Allow the LDML XML element extend to be passed to Insert.  This simplifies
  both client and library implementation.

b9e051e82d runtime: ignore signal 33 == SIGSETXID on GNU/Linux
When a cgo program calls setuid, setgid, etc., the GNU/Linux
pthread library sends signal SIGSETXID to each thread to tell
it to update its UID info.  If Go is permitted to intercept
the default SIGSETXID signal handler, the program will hang.

This patch tells the runtime package to not try to intercept
SIGSETXID on GNU/Linux.  This will be odd if a Go program
wants to try to use that signal, but it means that cgo
programs that call setuid, etc., won't hang.

eeffa738a9 encoding/asn1: promote untyped strings to UTF8 as needed.
Previously, strings that didn't have an explicit ASN.1 string type
were taken to be ASN.1 PrintableStrings. This resulted in an error if
a unrepresentable charactor was included.

For compatibility reasons, I'm too afraid to switch the default string
type to UTF8String, but this patch causes untyped strings to become
UTF8Strings if they contain a charactor that's not valid in a
PrintableString.

685a61df7e crypto/x509: exempt broken Entrust certificate from checks.
Entrust have issued a root certificate that's not marked as valid for
signing certificates.

This results in Go programs failing to validate certificates that
chain up to this root (i.e. gateway.push.apple.com:2195).

Although this is clearly a mistake on Entrust's part, it seems that we
will have to bodge around it.

51ff2ef409 encoding/json: simplify (*decodeState).indirect
Removes an incorrect code comment and some superfluous variables.

The comment I removed says that struct fields which implement
Unmarshaler must be pointers, even if they're in an addressable
struct. That's not the case, and there's already a test in decode_test.go
that demonstrates as much.

Encoding/json has quite a few assignments of reflect.Values to extra
variables – things like "iv := v" when there's no need to make a copy. I
think these are left over from a previous version of the reflect API. If they
aren't wanted, I wouldn't mind going through the package and getting
rid of the rest of them.

benchmark       old ns/op    new ns/op    delta
BenchmarkNow          197           33  -83.05%

This should make profiling a little better on OS X.
The raw time saved is unlikely to matter: what likely matters
more is that it seems like OS X sends profiling signals on the
way out of system calls more often than it should; avoiding
the system call should increase the accuracy of cpu profiles.

The 386 version would be similar but needs to do different
math for CPU speeds less than 1 GHz. (Apparently Apple has
never shipped a 64-bit CPU with such a slow clock.)

dcc46388df time: accept .999 in Parse
The recent shuffle in parsing formats exposed probably unintentional
behavior in time.Parse, namely that it was mostly ignoring ".99999"
in the format, producing the following behavior:

fmt.Println(time.Parse("03:04:05.999 MST", "12:00:00.888 PDT")) // error (.888 unexpected)
fmt.Println(time.Parse("03:04:05.999", "12:00:00")) // error (input too short)
fmt.Println(time.Parse("03:04:05.999 MST", "12:00:00 PDT"))  // ok (extra bytes on input make it ok)

http://play.golang.org/p/ESJ1UYXzq2

API CHANGE:

This CL makes all three examples valid: ".999" can match an
empty string or else a fractional second with at most nine digits.

Fixes #3701.

baf91c313f runtime: lower memory overhead of heap profiling.
The previous code was preparing arrays of entries that would be
filled if there was one entry every 128 bytes. Moving to a 4096
byte interval reduces the overhead per megabyte of address space
to 2kB from 64kB (on 64-bit systems).
The performance impact will be negative for very small MemProfileRate.

cb62365f57 net/http: reuse http proxy connections for different http requests
Comment on cache keys above connectMethod says "http to proxy, http
anywhere after that", however in reality target address was always
included, which prevented http requests to different target
addresses to reuse the same http proxy connection.

Comparing Go 1.0.1 and the complete unroll (this CL):

benchmark               old MB/s     new MB/s  speedup
md5.BenchmarkHash1K       142.64       419.18    2.94x
md5.BenchmarkHash8K       144.14       432.13    3.00x

On the same machine, 'openssl speed md5' reports 441 MB/s
and 531 MB/s for our two cases, so this CL is at 90% and 80% of
those speeds, which is at least in the right ballpark.
OpenSSL is using carefully engineered assembly, so we are
unlikely to catch up completely.

Measurements on a Mid-2010 MacPro5,1.

f26d61731d go/parser: fix comment grouping (day 1 bug)
Comment groups must end at the end of a line (or the
next non-comment token) if the group started on a line
with non-comment tokens.

This is important for correct computation of "lead"
and "line" comments (Doc and Comment fields in AST nodes).

Without this fix, the "line" comment for F1 in the
following example:

type T struct {
     F1 int // comment1
     // comment2
     F2 int
}

is "// comment1// comment2" rather than just "// comment1".

This bug was present from Day 1 but only visible when
looking at export-filtered ASTs where only comments
associated with AST nodes are printed, and only in rare
cases (e.g, in the case above, if F2 where not exported,
godoc would show "// comment2" anyway because it was
considered part of the "line" comment for F1).

The bug fix is very small (parser.go). The bulk of the
changes are additional test cases (parser_test.go).

The fix exposed a caching bug in go/printer via one of the
existing tests, hence the changes to printer.go.

As an aside, the fix removes the the need for empty lines
before an "// Output" comment for some special cases of
code examples (e.g.: src/pkg/strings/example_test.go, Count
example).

No impact on gofmt formatting of src, misc.

Fixes #3139.

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.)

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.

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.

method could probably be rolled into huffmanBlock and copyHist, but

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.

Don't foster-parent text nodes that consist only of whitespace.
(I implemented this entirely in inTableIM instead of creating an
inTableTextIM, because the sole purpose of inTableTextIM seems to be
to combine character tokens into a string, which our tokenizer does
already.)

Use parseImpliedToken to clarify a couple of cases.

Handle <style>, <script>, <input>, and <form>.

Ignore doctype tokens.

Pass 20 additional tests.

87eaa4cd0c mime/multipart: report io.EOF correctly on part ending without newlines
If a part ends with "--boundary--", without a final "\r\n",
that's also a graceful EOF, and we should return io.EOF instead

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
         181

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.

I have a small web server that simply sets several cookies

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

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.

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.

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.

5390722100 exp/types: generalized GCImporter API.
- Renamed ExportData -> FindGcExportData
  and base it on an a bufio.Reader rather
  than a filename so it can be used in
  environments where object files are
  stored elsewhere.

- Factor former GcImporter into GcImportData
  and GcImport. Implementations with different
  storage locations for object files can build
  a customized GcImport using GcImportData.

This is pkg/exp only - no impact on Go 1.

1d8ec87135 crypto/tls: don't select ECC ciphersuites with no mutual curve.
The existing code that tried to prevent ECC ciphersuites from being
selected when there were no mutual curves still left |suite| set.
This lead to a panic on a nil pointer when there were no acceptable

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.

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.

into *DB.putConn, which conditionally ignores the freelist
addition if the driver signaled ErrBadConn, introduced in a

This affects corner (test) cases only; gofmt -w src misc
doesn't cause any changes.

- added additional test cases
- removed doIndent parameter from printer.valueSpec
  (was always false)
- gofmt -w src misc causes no changes

Fixes #1207.

c9e5600f7d runtime: move runtime.write back to C
It may have to switch stacks, since we are calling
a DLL instead of a system call.

badcallback says where it is, because it is being called

36aa7d4d14 runtime: inline calls to notok
When a very low-level system call that should never fail
does fail, we call notok, which crashes the program.
Often, we are then left with only the program counter as
information about the crash, and it is in notok.
Instead, inline calls to notok (it is just one instruction
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.

Fixes #3219.
