This makes YCbCr match the other image types (e.g. RGBA, Gray) in
that an image's bounds is not restricted to the positive quadrant.
Also optimize the YCbCr draw code by hoisting some computation
outside of the loop.

Like https://golang.org/cl/4681044/ I don't think a gofix is
feasible. People will have to make manual changes. On the other hand,
directly manipulating YCbCr images is relatively rare, compared to
RGBA images, and if other code just uses the jpeg and draw packages
instead of messing directly with a YCbCr's []byte representations,
then things should just continue to work.

Previously, a timeout (in int64 nanoseconds) applied to a granularity
even smaller than one operation: a 100 byte read with a 1 second timeout
could take 100 seconds, if the bytes all arrived on the network 1 second
apart. This was confusing.
Rather than making the timeout granularity be per-Read/Write,
this CL makes callers set an absolute deadline (in time.Time)
after which operations will fail. This makes it possible to
set deadlines at higher levels, without knowing exactly how

First was, apart from adding tests, a single line of code (to add the

generator function the constructor function now uses a crypto.Hash

This CL improves the xml package in the following ways:
- makes its interface match established conventions
- brings Marshal and Unmarshal closer together
- fixes a large number of bugs and adds tests
- improves speed significantly
- organizes and simplifies the code
Fixes#2426.
Fixes#2406.
Fixes#1989.
What follows is a detailed list of those changes.
- All matching is case sensitive without special processing
to the field name or xml tag in an attempt to match them.
Customize the field tag as desired to match the correct XML
elements.
- Flags are ",flag" rather than "flag". The names "attr",
"chardata", etc, may be used to name actual XML elements.
- Overriding of attribute names is possible with "name,attr".
- Attribute fields are marshalled properly if they have
non-string types. Previously they were unmarshalled, but were
ignored at marshalling time.
- Comment fields tagged with ",comment" are marshalled properly,
rather than being marshalled as normal fields.
- The handling of the Any field has been replaced by the ",any"
flag to avoid unexpected results when using the field name for
other purposes, and has also been fixed to interact properly
with name paths. Previously the feature would not function
if any field in the type had a name path in its tag.
- Embedded struct support fixed and cleaned so it works when
marshalling and also when using field paths deeper than one level.
- Conflict reporting on field names have been expanded to cover
all fields. Previously it'd catch only conflicts of paths
deeper than one level. Also interacts correctly with embedded
structs now.
- A trailing '>' is disallowed in xml tags. It used to be
supported for removing the ambiguity between "attr" and "attr>",
but the marshalling support for that was broken, and it's now
unnecessary. Use "name" instead of "name>".
- Fixed docs to point out that a XMLName doesn't have to be
an xml.Name (e.g. a struct{} is a good fit too). The code was
already working like that.
- Fixed asymmetry in the precedence of XML element names between
marshalling and unmarshalling. Marshal would consider the XMLName
of the field type before the field tag, while unmarshalling would
do the opposite. Now both respect the tag of the XMLName field
first, and a nice error message is provided in case an attempt
is made to name a field with its tag in a way that would
conflict with the underlying type's XMLName field.
- Do not marshal broken "<???>" tags when in doubt. Use the type
name, and error out if that's not possible.
- Do not break down unmarshalling if there's an interface{} field
in a struct.
- Significant speed boost due to caching of type metadata and
overall allocation clean ups. The following timings reflect
processing of the the atom test data:
Old:
BenchmarkMarshal 50000 48798 ns/op
BenchmarkUnmarshal 5000 357174 ns/op
New:
BenchmarkMarshal 100000 19799 ns/op
BenchmarkUnmarshal 10000 128525 ns/op

- the main changes are removing the Doc suffix
from the exported types, so instead of
doc.TypeDoc one will have doc.Type, etc.
- All exported types now have a Name (or Names) field.
For Values, the Names field lists all declared variables
or constants.
- Methods have additional information about where they are
coming from.
- There's a mode field instead of a bool to
control the package's operation, which makes
it easier to extend w/o API changes.
Except for the partially implemented new Method type,
this is based on existing code. A clean rewrite is in
progress based on this new API.

In a test that does
func TestFoo(t *testing.T) {
defer cleanup()
t.Fatal("oops")
}
it can be important that cleanup run as the test fails.
The old code did this in Fatal:
t.signal <- t
runtime.Goexit()
The runtime.Goexit would run the deferred cleanup
but the send on t.signal would cause the main test loop
to move on and possibly even exit the program before
the runtime.Goexit got a chance to run.
This CL changes tRunner (the top stack frame of a test
goroutine) to send on t.signal as part of a function
deferred by the top stack frame. This delays the send
on t.signal until after runtime.Goexit has run functions
deferred by the test itself.
For the above TestFoo, this CL guarantees that cleanup
will run before the test binary exits.
This is particularly important when cleanup is doing
externally visible work, like removing temporary files
or unmounting file systems.

- Changed the Scan API semantics slightly:
The token literal string is only returned
if the token is a literal, comment, semicolon,

token literal value is determined by the token
value.
Clients that care about the token literal value
when not present can always use the following
piece of code:
pos, tok, lit := scanner.Scan()
if lit == "" {
lit = tok.String()
}
- Changed token.Lookup API to use a string instead
of a []byte argument.
- Both these changes were long-standing TODOs.

4) Have Write() not stomp the current line. It now erases the current

No visible external changes yet. The current approach is
a stop-gap approach: For methods of anonymous fields to be
seen, the anonymous field's types must be exported.
Missing: computing the actual MethodDocs and displaying them.
(Depending on the operation mode of godoc, the input to go/doc
is a pre-filtered AST with all non-exported nodes removed. Non-
exported anonymous fields are not even seen by go/doc in this
case, and it is impossible to collect associated (even exported)
methods. A correct fix will require some more significant re-
engineering; AST filtering will have to happen later, possibly
inside go/doc.)

Collapse the arch,os-specific directories into the main directory

There are no substantial edits here, except to the Makefile.
The assumption is that the Go tool will #define GOOS_darwin
and GOARCH_amd64 and will make any file named something
like signals_darwin.h available as signals_GOOS.h during the
build. This replaces what used to be done with -I$(GOOS).
There is still work to be done to make runtime build with
standard tools, but this is a big step. After this we will have

being copied out of deleted files.
There is no new code here.
Suppose you have a portable implementation for Sin
and a 386-specific assembly one. The old way to
do this was to write three files
sin_decl.go
func Sin(x float64) float64 // declaration only
sin_386.s
assembly implementation
sin_port.go
func Sin(x float64) float64 { ... } // pure-Go impl
and then link in either sin_decl.go+sin_386.s or
just sin_port.go. The Makefile actually did the magic
of linking in only the _port.go files for those without
assembly and only the _decl.go files for those with
assembly, or at least some of that magic.
The biggest problem with this, beyond being hard
to explain to the build system, is that once you do
explain it to the build system, godoc knows which
of sin_port.go or sin_decl.go are involved on a given
architecture, and it (correctly) ignores the other.
That means you have to put identical doc comments
in both files.
The new approach, which is more like what we did
in the later packages math/big and sync/atomic,
is to have
sin.go
func Sin(x float64) float64 // decl only
func sin(x float64) float64 {...} // pure-Go impl
sin_386.s
// assembly for Sin (ignores sin)
sin_amd64.s
// assembly for Sin: jmp sin
sin_arm.s
// assembly for Sin: jmp sin
Once we abandon Makefiles we can put all the assembly
stubs in one source file, so the number of files will
actually go down.
Chris asked whether the branches cost anything.
Given that they are branching to pure-Go implementations
that are not typically known for their speed, the single
direct branch is not going to be noticeable. That is,
it's on the slow path.
An alternative would have been to preserve the old
"only write assembly files when there's an implementation"
and still have just one copy of the declaration of Sin
(and thus one doc comment) by doing:
sin.go
func Sin(x float64) float64 { return sin(x) }
sin_decl.go
func sin(x float64) float64 // declaration only
sin_386.s
// assembly for sin
sin_port.go
func sin(x float64) float64 { portable code }
In this version everyone would link in sin.go and
then either sin_decl.go+sin_386.s or sin_port.go.
This has an extra function call on all paths, including
the "fast path" to get to assembly, and it triples the
number of Go files involved compared to what I did
in this CL. On the other hand you don't have to
write assembly stubs. After starting down this path
I decided that the assembly stubs were the easier
approach.
As for generating the assembly stubs on the fly, much
of the goal here is to eliminate magic from the build
process, so that zero-configuration tools like goinstall
or the new go tool can handle this package.

Example:
PACKAGE
package utf8
import "unicode/utf8"
Package utf8 implements functions and constants to support text
encoded in UTF-8. This package calls a Unicode character a rune for
brevity.
CONSTANTS
const (
RuneError = unicode.ReplacementChar // the "error" Rune or "replacement character".
RuneSelf = 0x80 // characters below Runeself are represented as themselves in a single byte.
UTFMax = 4 // maximum number of bytes of a UTF-8 encoded Unicode character.
)
Numbers fundamental to the encoding.
FUNCTIONS
func DecodeLastRune(p []byte) (r rune, size int)
DecodeLastRune unpacks the last UTF-8 encoding in p and returns the
rune and its width in bytes.
func DecodeLastRuneInString(s string) (r rune, size int)
DecodeLastRuneInString is like DecodeLastRune but its input is a
string.
func DecodeRune(p []byte) (r rune, size int)
DecodeRune unpacks the first UTF-8 encoding in p and returns the rune
and its width in bytes.
func DecodeRuneInString(s string) (r rune, size int)
DecodeRuneInString is like DecodeRune but its input is a string.
func EncodeRune(p []byte, r rune) int
EncodeRune writes into p (which must be large enough) the UTF-8
encoding of the rune. It returns the number of bytes written.
func FullRune(p []byte) bool
FullRune reports whether the bytes in p begin with a full UTF-8
encoding of a rune. An invalid encoding is considered a full Rune
since it will convert as a width-1 error rune.
func FullRuneInString(s string) bool
FullRuneInString is like FullRune but its input is a string.
func RuneCount(p []byte) int
RuneCount returns the number of runes in p. Erroneous and short
encodings are treated as single runes of width 1 byte.
func RuneCountInString(s string) (n int)
RuneCountInString is like RuneCount but its input is a string.
func RuneLen(r rune) int
RuneLen returns the number of bytes required to encode the rune.
func RuneStart(b byte) bool
RuneStart reports whether the byte could be the first byte of an
encoded rune. Second and subsequent bytes always have the top two
bits set to 10.
func Valid(p []byte) bool
Valid reports whether p consists entirely of valid UTF-8-encoded
runes.
func ValidString(s string) bool
ValidString reports whether s consists entirely of valid UTF-8-encoded
runes.
TYPES
type String struct {
// contains filtered or unexported fields
}
String wraps a regular string with a small structure that provides
more efficient indexing by code point index, as opposed to byte index.
Scanning incrementally forwards or backwards is O(1) per index
operation (although not as fast a range clause going forwards).
Random access is O(N) in the length of the string, but the overhead is
less than always scanning from the beginning. If the string is ASCII,
random access is O(1). Unlike the built-in string type, String has
internal mutable state and is not thread-safe.
func NewString(contents string) *String
NewString returns a new UTF-8 string with the provided contents.
func (s *String) At(i int) rune
At returns the rune with index i in the String. The sequence of runes
is the same as iterating over the contents with a "for range" clause.
func (s *String) Init(contents string) *String
Init initializes an existing String to hold the provided contents.
It returns a pointer to the initialized String.
func (s *String) IsASCII() bool
IsASCII returns a boolean indicating whether the String contains only
ASCII bytes.
func (s *String) RuneCount() int
RuneCount returns the number of runes (Unicode code points) in the
String.
func (s *String) Slice(i, j int) string
Slice returns the string sliced at rune positions [i:j].
func (s *String) String() string
String returns the contents of the String. This method also means the
String is directly printable by fmt.Print.

To allow these types as map keys, we must fill in
equal and hash functions in their algorithm tables.
Structs or arrays that are "just memory", like [2]int,
can and do continue to use the AMEM algorithm.
Structs or arrays that contain special values like
strings or interface values use generated functions
for both equal and hash.
The runtime helper func runtime.equal(t, x, y) bool handles
the general equality case for x == y and calls out to
the equal implementation in the algorithm table.
For short values (<= 4 struct fields or array elements),
the sequence of elementwise comparisons is inlined
instead of calling runtime.equal.

According to http://www.ietf.org/rfc/rfc4254.txt most channel messages contain the channel id of the recipient channel, not the sender id. This allows the recipient connection multiplexer to route the message to the correct channel.
This changeset fixes several messages that incorrectly send the local channel id instead of the remote channel's id.
While sessions were being created and closed in sequence channels in the channel pool were freed and reused on the server side of the connection at the same rate as was done on the client, so the channel local and remote channel ids always corresponded. As soon as I had concurrent sessions on the same clientConn the server started to complain of 'uknown channel id N' where N is the local channel id, which is actually paired with server channel id K.

Wait. Exec calls Wait internally and so blocks until the remote
command is complete.
Credit to Gustavo Niemeyer for the impetus for this CL.

My excuse for doing this is that test cases with newlines in them didn't
work. But instead of just fixing that, I rearranged everything in
parse_test.go to use fewer channels and pipes, and just call a
straightforward function to read test cases from a file.

Slight slow-down for printer benchmark (-0.7%) before
applying CL 5416049 (which will wash it out). Code is
cleaner and simpler.

Preamble to the simplification of the template API.
Although the signature of Parse (nee Set) changes,
it's really an internal function, used only by
text/template.

Parse {{define}} blocks during template parsing rather than separately as a set-specific thing.
This cleans up set parse significantly, and enables the next step, if we want, to unify the
API for templates and sets.
Other than an argument change to parse.Parse, which is in effect an internal function and
unused by client code, there is no API change and no spec change yet.

This feature should make it easier to look at very large
directory trees.
- a new mode (URL: /pkg/?m=flat) shows directory listings w/o
indentation and entries with full path (html and text mode)
- in text mode, hierarchical (non-flat) directory listings are
now presented with indentation (/pkg/?m=text)
- in html mode, hierarchical (non-flat) directory listings are
presented with slightly less indentation
- there is an internal hook for programmatic control of the
display mode (for specialized versions of godoc).

Work around a bug that was fixed after OpenBSD 5.0 - a request for
kern.hostname or kern.domainname with a nil value for oldp will result
in a length of zero being returned. If we hit this case use a length
of MAXHOSTNAMELEN (256).

Move the existing darwin/freebsd specific nametomib implementation
into the respective operating system dependent files.
Provide a nametomib implementation for openbsd, which operates on a
sysctl MIB that has been pre-generated from the various system headers
by mksysctl_openbsd.pl.

Making Value opaque means we can drop the interface kludges
in favor of a significantly simpler and faster representation.
v.Kind() will be a prime candidate for inlining too.

I cannot explain why BenchmarkSkipValue gets faster.
Maybe it is one of those code alignment things.

Fixes use of c after Dial failure (causes crash).
May fix Dial failure by listening to 127.0.0.1:0
instead of 0.0.0.0:0 (tests should only listen on
localhost).

The wrong length was being sent, and two parameters
were also transposed. Made the record type be a type

of bug in the future.

text/template does this (in an entirely different way), so
make html/template do the same. Before this fix, the template
{{.}} given a pointer to a string prints its address instead of its
value.

Ensure that empty NameLists always return
a zero length []string, not nil.
In practice NameLists are only used in a few
message types and always consumed by a for
range function so the difference between nil
and []string{} is not significant.
Also, add exp/ssh to pkg/Makefile as suggested
by rsc.
