Gotest tries to build things, for which it invokes make,
and it was too hard to coordinate go invoking gotest
invoking go to build the test binary, so put all the code
here instead. Gotest will be deleted once we switch.
The only code that really made sense to copy verbatim
was the flag parsing.
This remains a work in progress. There are still plenty
of things to clean up and make better, but this is a good
checkpoint. It can run all the tests in the tree (except
runtime, which it can't build yet).

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.

Equality on structs will require arbitrary code for type equality,

In the process, trim top-level map structure from

Equality on structs will require being able to call code generated

An experiment: allow structs to be copied even if they
contain unexported fields. This gives packages the
ability to return opaque values in their APIs, like reflect
does for reflect.Value but without the kludgy hacks 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
in this CL or by using an interface type.
All in one CL so that it can be rolled back more easily if
we decide this is a bad idea.

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.

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.

goinstall has built in support for a few common code hosting sites. The
identification of which vcs tool should be used was based purely on a
regex match against the provided import path. The problem with this
approach is that it requires distinct import paths for different vcs
tools on the same site.
Since bitbucket has recently starting hosting Git repositories under the
same bitbucket.org/user/project scheme as it already hosts Mercurial
repositories, now would seem a good time to take a more flexible
approach.
We still match the import path against a list of regexes, but now the
match is purely to distinguish the different hosting sites. Once the
site is identified, the specified function is called with the repo and
path matched out of the import string. This function is responsible for
creating the vcsMatch structure that tells us what we need to download
the code.
For github and launchpad, only one vcs tool is currently supported, so
these functions can simply return a vcsMatch structure. For googlecode,
we retain the behaviour of determing the vcs from the import path - but
now it is done by the function instead of the regex. For bitbucket, we
use api.bitbucket.org to find out what sort of repository the specified
import path corresponds to - and then construct the appropriate vcsMatch
structure.

Adds check that, for example, a Scan method taking
a first argument of type fmt.ScanState has the correct
signature to satisfy fmt.Scanner.
Similarly, a ReadByte should return byte, os.Error.
These are important to check because various pieces
of code (fmt, gob, json, flate) do dynamic checks
for these methods, so code with incorrect signatures
would not be flagged at compile time.
These become even more important to check when
rune is introduced.

The loop recognizer uses the standard dominance
frontiers but gets confused by dead code, which
has a (not explicitly set) rpo number of 0, meaning it
looks like the head of the function, so it dominates
everything. If the loop recognizer encounters dead
code while tracking backward through the graph
it fails to recognize where it started as a loop, and
then the optimizer does not registerize values loaded
inside that loop. Fix by checking rpo against rpo2r.
Separately, run a quick pass over the generated
code to squash JMPs to JMP instructions, which
are convenient to emit during code generation but
difficult to read when debugging the -S output.
A side effect of this pass is to eliminate dead code,
so the output files may be slightly smaller and the
optimizer may have less work to do.
There is no semantic effect, because the linkers
flatten JMP chains and delete dead instructions
when laying out the final code. Doing it here too
just makes the -S output easier to read and more
like what the final binary will contain.
The "dead code breaks loop finding" bug is thus
fixed twice over. It seemed prudent to fix loopit
separately just in case dead code ever sneaks back
in for one reason or another.

image.PalettedColorModel -> color.Palette
image.RGBAColor -> color.RGBA
image.RGBAColorModel -> color.RGBAModel

image.RGBA64ColorModel -> color.RGBA64Model
(similarly for NRGBAColor, GrayColorModel, etc)
The image.ColorImage type stays in the image package, but is renamed:
image.ColorImage -> image.Uniform
The image.Image implementations (image.RGBA, image.RGBA64, image.NRGBA,
image.Alpha, etc) do not change their name, and gain a nice symmetry:
an image.RGBA is an image of color.RGBA, etc.
The image.Black, image.Opaque uniform images remain unchanged (although
their type is renamed from image.ColorImage to image.Uniform). The
corresponding color types (color.Black, color.Opaque, etc) are new.
Nothing in the image/ycbcr is renamed yet. The ycbcr.YCbCrColor and

The map implementation was using the C idiom of using
a pointer just past the end of its table as a limit pointer.
Unfortunately, the garbage collector sees that pointer as
pointing at the block adjacent to the map table, pinning
in memory a block that would otherwise be freed.
Fix by making limit pointer point at last valid entry, not
just past it.

When a line directive was encountered we would push a new 'z' entry into
the history to indicate the start of new file attributation, and a 'Z'
entry to change line numbering. However we didn't pop the 'z' entry, so
we were actually corrupting the history stack. The most obvious
occurance of this was in the code that build the symbol tables for the
DWARF information - where an internal stack in the linker would overflow
when more than a few line directives were encountered in a single stack
(Issue 1878). So now we pop the 'z' entry when we encounter the end of
the file that the directive was in, which maintains the history stack
integrity.
Also, although new 'z' entries for new files had relative paths
expanded, the same was not done for line directives. Now we do it for
line directives also - so that the now correct DWARF information has the
full path available.

- explicitly detect type switches (as opposed to detecting
regular (expression switches) and then do extra testing
for type switches
- fix all outstanding TODOs in parser.go

This CL changes both JoinGroup and LeaveGroup methods
to take an interface as an argument for enabling IPv6
group address join/leave, join a group address on a
specific interface.

This is just moving the URL code from package http into its own package,
which has been planned for a while.
Besides clarity, this also breaks a nascent dependency cycle the new template
package was about to introduce.
Add a gofix module, url, and use it to generate changes outside http and url.
Sadness about the churn, gladness about some of the naming improvements.

When the C API being used includes multiple names for the same
underlying symbol (e.g. multiple #define's for the same variable), then
cgo will generate the same placeholder variables for each name. This
then prevents the code from compiling due to multiple declarations of
the same variable - so change cgo to only create one instance of the
variable for the underlying symbol.

. Added USED() attribute.
src/cmd/6c/cgen.c:
. Revised code around "REGARG" to resemble use in "8c" and
consequently remove a warning.

Since the posLink_url also adds a non-URL attribute, the quoting and URL-escaping
must happen inside posLink_url (otherwise the non-URL attribute becomes part or the
URL portion of the tag.

- rename template funcs for better consistency and
sort them into groups of related functionality
- try to be more consistent with html vs url escaping

- simplified pipelines
- simplified templates by using template variables
- converted most old-style formatters into new-style funcs
- fixed some escaping bugs (use of url escaping where it was missing)

- first step; rough conversion of all template files
- there is plenty of opportunity for cleanups/simplifications (next CLs)
- html and text output as before

The change adds specialized type algorithms
for slices and types of size 8/16/32/64/128.
It significantly accelerates chan and map operations
for most builtin types as well as user structs.
