Restore package os/signal, with new API:
Notify replaces Incoming, allowing clients
to ask for certain signals only. Also, signals
go to everyone who asks, not just one client.
This could plausibly move into package os now
that there are no magic side effects as a result
of the import.
Update runtime for new API: move common Unix
signal handling code into signal_unix.c.

If a printer is configured with the SourcePos mode
set, it will emit //-line comments as necessary to
ensure that the result - if reparsed - reflects the
original source position information.
This change required a bit of reworking of the
output section in printer.go. Specifically:
- Introduced new Config mode 'SourcePos'.
- Introduced new position 'out' which tracks the
position of the generated output if it were read
in again. If there is a discrepancy between out
and the current AST/source position, a //line
comment is emitted to correct for it.
- Lazy emission of indentation so that //line
comments can be placed correctly. As a result,
the trimmer will have to do less work.
- Merged writeItem into writeString.
- Merged writeByteN into writeByte.
- Use a []byte instead of a byte.Buffer both in the
printer and in the trimmer (eliminates dependency).
Also: introduced explicit printer.Mode type (in
sync w/ parser.Mode, scanner.Mode, etc.)

Issue 2856 asks for a rename of a few methods to a
more idiomatic Go style. This is a very early API
that evolved organically throughout the years.
Together with the fact that ErrorVectors were embedded
in other data structures (e.g. Parser), just renaming
methods (e.g. GetError -> Error) would lead to undesired
behavior (e.g., Parser would act like an Error). Instead,
cleaned up API a bit more:
- removed ErrorVector in favor of ErrorList (already
present)
- simplified Scanner.Init by making the error handler a
function instead of requiring an ErrorHandler implementation
- adjusted helper functions accordingly
- updated Go 1 doc

deletion of code): Because method conflicts due to embedding
must always be detected, remove any premature elimination of

The implementation is divided into 4 phases:

2) reading of a possibly filtered AST (reader.go: type reader)
3) method set computation (reader.go)
4) sorting and creation of final documentation (reader.go)
In contrast to the old implementation, the presentation data
(Names, Docs, Decls, etc.) are created immediately upon reading
the respective AST node. Also, all types are collected (embedded
or not) in a uniform way.
Once the entire AST has been processed, all methods and types
have been collected and the method sets for each type can be
computed (phase 3).
To produce the final documentation, the method sets and value
maps are sorted.

The bitLen function currently shifts out blocks of 8 bits at a time.
This change replaces this sorta-linear algorithm with a log(N)
one (shift out 16 bits, then 8, then 4, then 2, then 1).
I left the start of it linear at 16 bits at a time so that
the function continues to work with 32 or 64 bit values
without any funkiness.
The algorithm is similar to several of the nlz ("number of
leading zeros") algorithms from "Hacker's Delight" or the
"bit twiddling hacks" pages.
Doesn't make a big difference to the existing benchmarks, but
I'm using the code in a different context that calls bitLen
much more often, so it seemed worthwhile making the existing
codebase faster so that it's a better building block.

This lets the client of go/build specify additional tags that
can be recognized in a // +build directive. For example,
a build for a custom environment like App Engine might
include "appengine" in the BuildTags list, so that packages
can be written with some files saying
// +build appengine (build only on app engine)
or
// +build !appengine (build only when NOT on app engine)
App Engine here is just a hypothetical context. I plan to use
this in the cmd/go sources to distinguish the bootstrap version
of cmd/go (which will not use networking) from the full version
using a custom tag. It might also be useful in App Engine.

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

- 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.

- exports.go contains a stripped-down (but semantically unchanged)
version of the code in go/ast/filter.go for export filtering
- filter.go contains the documentation filtering code found before
at the end of doc.go; this is simply a code move w/o any semantic
changes
- godoc now relies on go/doc for export filtering when creating
documentation. It still has a separate form of export filtering
for showing the source code version. This needs to be consolidated
(perhaps the source form view should just be removed?).
- Stripping of function bodies (stripFunctionBodies function of
godoc.go) is now happening in doc.go (line 176).
- doc.NewPackageDoc has an extra parameter "exportsOnly. If set
to false, the behavior is as before. This function is only called
once in our source code; a gofix module is probably not warranted.
- Deleted doc.NewFileDoc - was never called.
This change is mostly a code move w/ some minimal tweaks. It should
not cause any changes to the behavior of godoc. It's a prerequisite
for extracting anonymous embedded fields.

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.)

This will be nicer to the automatic tools.
It requires a few more assembly stubs
but fewer Go files.
There are a few instances where it looks like
there are new blobs of code, but they are just
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

Although FIPS 186-3 says that we should truncate the hashes, at least
one other library (libgcrypt) doesn't. This means that it's impossible
to interoperate with code using gcrypt if we enforce the truncation

This change shouldn't actually affect anything because nearly

I added the clientChan's msg channel to the list of channels that are closed in mainloop when the server sends a channelCloseMsg.
I added an ExitError type that wraps a Waitmsg similar to that of os/exec. I fill ExitStatus with the data returned in the 'exit-status' channel message and Msg with the data returned in the 'exit-signal' channel message.
Instead of having Wait() return on the first 'exit-status'/'exit-signal' I have it return an ExitError containing the status and signal when the clientChan's msg channel is closed.
I added two tests cases to session_test.go that test for exit status 0 (in which case Wait() returns nil) and exit status 1 (in which case Wait() returns an ExitError with ExitStatus 1)

This is part one of a small set of CL's that aim to resolve

Firstly, the hairy handling of assigning the peersId is now
done in one place. The cost of this change is the slightly
paradoxical construction of the partially created clientChan.
Secondly, by creating clientChan.stdin/out/err when the channel

This is a slight change to fmt's semantics, but means that if you use

This came up because Time.Month() couldn't cleanly print as an integer

The SSH spec allows for the server to send a banner message to the client at any point during the authentication process. Currently the ssh client auth types all assume that the first response from the server after issuing a userAuthRequestMsg will be one of a couple of possible authentication success/failure messages. This means that client authentication breaks if the ssh server being connected to has a banner message configured.

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.

An experiment: allow structs to be copied even if they

ability to return opaque values in their APIs, like reflect

resorts to.
In general, we trust programmers not to do silly things
like *x = *y on a package's struct pointers, just as we trust
programmers not to do unicode.Letter = unicode.Digit,
but packages that want a harder guarantee can introduce
an extra level of indirection, like in the changes to os.File

All in one CL so that it can be rolled back more easily if

Currently, the state transition functions in the HTML parser
return the next insertion mode and whether the token is consumed.
This works well except for when one insertion mode needs to use
the rules for another insertion mode. Then the useTheRulesFor
function needs to patch things up. This requires comparing functions
for equality, which is going to stop working.
Adding a field to the parser structure to store the current
insertion mode eliminates the need for useTheRulesFor;
one insertion mode function can now just call the other
directly. The insertion mode will be changed only if it needs to be.

This looks like it is just moving some code from
time to runtime (and translating it to C), but the
runtime can do a better job managing the goroutines,
and it needs this functionality for its own maintenance
(for example, for the garbage collector to hand back
unused memory to the OS on a time delay).
Might as well have just one copy of the timer logic,
and runtime can't depend on time, so vice versa.
It also unifies Sleep, NewTicker, and NewTimer behind
one mechanism, so that there are no claims that one
is more efficient than another. (For example, today
people recommend using time.After instead of time.Sleep
to avoid blocking an OS thread.)

This does escaping on first execution.
template.go defines the same interface elements as package template.
It requires rather more duplication of code than I'd like, but I'm
not clear how to avoid that.
Maybe instead of
mySet.ParseGlob(...)
template.ParseSetGlob(...)
mySet.ParseFiles(...)
mySet.ParseTemplateFiles(...)
template.ParseTemplateFiles(...)
we combine these into a fileset abstraction that can be wrapped
var fileset template.FileSet
fileset.Glob(...) // Load a few files by glob
fileset.Files(...) // Load a few {{define}}d files
fileset.TemplateFiles(...) // Load a few files as template bodies
fileset.Funcs(...) // Make the givens func available to templates
// Do the parsing.
set, err := fileset.ParseSet()
// or set, err := fileset.ParseInto(set)
or provide an interface that can receive filenames and functions and
parse messages:
type Bundle interface {
TemplateFile(string)
File(string)
Funcs(FuncMap)
}
and define template.Parse* to handle the file-system stuff and send
messages to a bundle:
func ParseFiles(b Bundle, filenames ...string)

There are three classes of methods/functions called Error:
a) The Error method in the just introduced error interface
b) Error methods that create or report errors (http.Error, etc)
c) Error methods that return errors previously associated with
the receiver (Tokenizer.Error, rows.Error, etc).
This CL introduces the convention that methods in case (c)
should be named Err.
The reasoning for the change is:
- The change differentiates the two kinds of APIs based on
names rather than just on signature, unloading Error a bit
- Err is closer to the err variable name that is so commonly
used with the intent of verifying an error
- Err is shorter and thus more convenient to be used often
on error verifications, such as in iterators following the
convention of the sql package.

The existing code uses *os.Waitmsg as an os.Error,
but *os.Waitmsg is really just a stringer.
Introduce an explicit error type for the real error.
Not to be submitted until just before error goes in;
the gofix for error updates type assertions
err.(*os.Waitmsg)
to
err.(*exec.ExitError)
The seemingly redundant String method will become
an Error method when error goes in, and will no longer
be redundant.

Back then, every x.go file in a package became an x.6 file
in the archive. It was important to be able to allow the
use of long Go source file names, hence the increase in size.
Today, all Go source files compile into a single _go_.6 file
regardless of their names, so the archive file name length
no longer needs to be long. The longer name causes some
problems on Plan 9, where the native archive format is the
same but with 16-byte names, so revert back to 16.
