The tree is inconsistent about single l vs double l in those words in documentation, test messages, and one error value text. $ git grep -E '[Mm]arshall(|s|er|ers|ed|ing)' | wc -l 42 $ git grep -E '[Mm]arshal(|s|er|ers|ed|ing)' | wc -l 1694 Make it consistently a single l, per earlier decisions. This means contributors won't be confused by misleading precedence, and it helps consistency. Change the spelling in one error value text in newRawAttributes of crypto/x509 package to be consistent. This change was generated with: perl -i -npe 's,([Mm]arshal)l(|s|er|ers|ed|ing),$1$2,' $(git grep -l -E '[Mm]arshall' | grep -v AUTHORS | grep -v CONTRIBUTORS) Updates #12431.

<h2 id="2012-03-13">2012-03-13 (Go 1 Release Candidate 1)</h2>
|
|
|
|
<pre>
|
|
This weekly snapshot is very close to what we expect will be the contents of
|
|
the Go 1 release. There are still a few minor documentation issues to resolve,
|
|
and a handful of bugs that should be addressed before the release, but the vast
|
|
majority of Go programs should be completely unaffected by any changes we make
|
|
between now and the full release.
|
|
|
|
If you're interested in helping us test, eager to try out Go 1, or just
|
|
curious, this weekly snapshot is the one to try. We'll issue a new App Engine
|
|
Go 1 beta SDK very soon, so if you're an App Engine user you can try it there
|
|
too.
|
|
|
|
To help us focus on any remaining bugs and avoid introducing new ones, we will
|
|
restrict our attention to critical fixes and issues marked Go1-Must in the
|
|
issue tracker. Everything non-essential will be held until after the Go 1
|
|
release is cut and in the field for a while.
|
|
|

|
|
Its FindTree, ScanDir, Tree, and DirInfo types have been replaced with the

This weekly snapshot includes changes to the os and runtime packages.
|
|
|
|
This should be the last of the significant incompatible changes before Go 1.
|
|
|
|
There are no longer error constants such as EINVAL in the os package, since the
|
|
set of values varied with the underlying operating system. There are new
|
|
portable functions like IsPermission to test common error properties, plus a
|
|
few new error values with more Go-like names, such as ErrPermission and
|
|
ErrNoEnv.
|
|
|
|
The os.Getenverror function has been removed. To distinguish between a
|
|
non-existent environment variable and an empty string, use os.Environ or
|
|
syscall.Getenv.
|
|
|
|
The Process.Wait method has dropped its option argument and the associated
|
|
constants are gone from the package. Also, the function Wait is gone; only the
|
|
method of the Process type persists.
|
|
|
|
The non-portable Waitmsg type has been replaced with the portable ProcessState.
|
|
|
|
Much of the API exported by package runtime has been removed in favor of
|
|
functionality provided by other packages. Code using the runtime.Type
|
|
interface or its specific concrete type implementations should now use package
|
|
reflect. Code using runtime.Semacquire or runtime.Semrelease should use
|
|
channels or the abstractions in package sync.
|
|
|
|
The runtime.Alloc, runtime.Free, and runtime.Lookup functions, an unsafe API
|
|
created for debugging the memory allocator, have no replacement.
|
|
|
|
The runtime.Cgocalls and runtime.Goroutines functions have been renamed to
|
|
runtime.NumCgoCall and runtime.NumGoroutine.
|
|
|
|
The "go fix" command will update code to accommodate most of these changes.
|
|
|
|
Other changes:
|

This release includes some package changes that require changes to client code.
|
|
|
|
The flate, gzip and zlib's NewWriterXxx functions no longer return an error.

ExpandEnv. The NewFile function now takes a uintptr and the *File.Fd method
|
|
returns a uintptr.

This weekly snapshot includes a re-organization of the Go tools.
|
|
|
|
Only the go, godoc, and gofmt tools are installed to $GOROOT/bin (or $GOBIN).
|
|
The remainder are installed to $GOROOT/bin/tool.
|
|
This puts the lesser-used tools (6g, cgo, govet, etc.) outside the user PATH.
|
|
Instead these tools may be called through the go tool with 'go tool command'.
|
|
For example, to vet hello.go you would type 'go tool vet hello.go'.
|
|
Type 'go tool' see the list of available tools.
|
|
|
|
With the move, some tools were given simpler names:
|
|
6cov -> cov
|
|
6nm -> nm
|
|
goapi -> api
|
|
gofix -> fix
|
|
gopack -> pack
|
|
gopprof -> pprof
|
|
govet -> vet
|
|
goyacc -> yacc
|
|
|
|
The os/signal package has been moved to exp/signal.
|
|
|
|
A new tool named 'dist' has been introduced to handle building the gc tool
|
|
chain and to bootstrap the go tool. The old build scripts and make files
|
|
have been removed.
|
|
|
|
Other changes:
|
|

This weekly snapshot renamed the html package to exp/html. The package will not
|
|
be present in the Go 1 distribution, but will be installable from source.
|
|
|
|
Error variables in the archive/tar, archive/zip, compress/gzip, compress/zlib,
|
|
and crypto/bcrypt packages have been renamed from FooError to ErrFoo.
|
|
There is no gofix, but the compiler will flag code that needs updating.

|
|
|
This weekly snapshot relocates many packages to sub-repositories of the main
|
|
Go repository. These are the old and new import paths:

This snapshot includes changes to the images/ycbcr and testing packages, and
|
|
changes to the build system.
|
|
|
|
The types for managing Y'CbCr images in the image/ycbcr have been moved to the
|
|
image and image/color packages. A gofix module will rewrite affected code.
|
|
|
|
The testing package's B type (used when running benchmarks) now has the same
|
|
methods as T (used in tests), such as Print, Error, and Fatal.
|
|
|
|
This weekly adds a new command named 'go' for building and testing go programs.
|
|
For Go 1, the go command will replace the makefile-based approach that we have
|
|
been using. It is not yet ready for general use, but all.bash does use it to
|
|
build the tree. If you have problems building the weekly, you can 'export
|
|
USE_GO_TOOL=false' before running all.bash to fall back to the makefiles.
|
|
|
|

|
|

This snapshot includes language changes and changes to goinstall and gofmt.
|
|
|
|
Equality and inequality (== and !=) are now defined for struct and array
|
|
values, respectively, provided the elements of the data structures can
|
|
themselves be compared. See the Go 1 release notes for the details:
|
|
http://weekly.golang.org/doc/go1.html#equality
|
|
|
|
The rune type is now an alias for int32 and character literals have the default
|
|
type of rune. Code that uses int where it should use rune will break.
|
|
See the Go 1 release notes for the details:
|
|
http://weekly.golang.org/doc/go1.html#rune
|
|
|
|
Goinstall now expects Google Code import paths to be of the form:
|
|
"code.google.com/p/go-tour/tree"
|
|
It will reject imports in the old style "go-tour.googlecode.com/hg/tree".
|
|
There is a gofix module to rename such imports.
|
|
Use goinstall -fix to update broken packages.
|
|
|
|
Gofmt's flags have been modified slightly.
|
|
The -tabintent flag has been renamed -tabs.

This snapshot includes a language change and changes to the strconv and go/doc
|
|
packages. The package changes require changes to client code.
|
|
The language change is backwards-compatible.
|
|
|
|
Type elision in arrays, slices, or maps of composite literals has been
|
|
extended to include pointers to composite literals. Code like this
|
|
var t = []*T{&T{}, &T{}}
|
|
may now be written as
|
|
var t = []*T{{}, {}}
|
|
You can use gofmt -s to simplify such code.
|
|
|
|
The strconv package has been given a more idiomatic and efficient interface.
|
|
Client code can be updated with gofix. See the docs for the details:
|
|
http://weekly.golang.org/pkg/strconv/
|
|
|
|
The go/doc package's ToHTML function now takes a []byte argument instead of a
|
|
string.
|
|
|
|
Other changes:
|
|
* crypto/aes: eliminate some bounds checking and truncation (thanks Rémy Oudompheng).
|
|
* crypto/x509: if a parent cert has a raw subject, use it.
|
|
* encoding/gob: don't send type info for unexported fields.
|
|
* exp/ssh: allow for msgUserAuthBanner during authentication (thanks Gustav Paul).
|
|
* fmt: benchmark floating point,
|
|
only use Stringer or Error for strings.
|
|
* gc: changes in export format in preparation of inlining,
|
|
disallow map/func equality via interface comparison,
|
|
use gofmt spacing when printing map type.
|
|
* go/doc: exclude lines ending in ':' from possible headings.
|
|
* gobuilder: -commit mode for packages,
|
|
cripple -package mode temporarily,
|
|
use new dashboard protocol.
|
|
* godoc: improved output of examples in html (thanks Volker Dobler).
|
|
* gofmt: handle &T in composite literal simplify.
|
|
* goinstall: honour -install=false flag when -make=true.
|
|
* hash: rewrite comment on Hash.Sum method.
|
|
* html: more parser improvements (thanks Andrew Balholm).
|
|
* image: avoid func comparison during ColorModel comparison.
|
|
* math: add special-cases comments to Sinh and Tanh (thanks Charles L. Dorian).
|
|
* misc/dashboard: further implementation work.
|
|
* net, syscall: remove BindToDevice from UDPConn, IPConn (thanks Mikio Hara).
|
|
* net/mail: correctly compare parsed times in the test.
|
|
* os/exec: make LookPath always search CWD under Windows (thanks Benny Siegert).
|
|
* runtime: prep for type-specific algorithms.
|
|
* strconv: 34% to 63% faster conversions.

This weekly snapshot includes changes to the hash package and a gofix for the
|
|
time and os.FileInfo changes in the last snapshot.
|
|
|
|
The hash.Hash's Sum method has been given a []byte argument,
|
|
permitting the user to append the hash to an existing byte slice.
|
|
Existing code that uses Sum can pass nil as the argument.
|
|
Gofix will make this change automatically.
|
|
|
|
Other changes:
|
|
* crypto/tls: cleanup certificate load on windows (thanks Alex Brainman).
|
|
* exp/ssh: add Std{in,out,err}Pipe methods to Session (thanks Dave Cheney).
|
|
* dashboard: don't choke on weird builder names.
|
|
* exp/ssh: export type signal, now Signal (thanks Gustav Paul).
|
|
* os: add ModeType constant to mask file type bits (thanks Gustavo Niemeyer).

<pre>
|
|
This weekly snapshot includes changes to the time, os, and text/template
|
|
packages. The changes to the time and os packages are significant and related.
|
|
Code that uses package time, package text/template, or package os's FileInfo
|
|
type will require changes.
|
|
|
|
In package time, there is now one type - time.Time - to represent times.
|
|
Note that time.Time should be used as a value, in contrast to old code
|
|
which typically used a *time.Time, a pointer to a large struct. (Drop the *.)
|
|
Any function that previously accepted a *time.Time, an int64
|
|
number of seconds since 1970, or an int64 number of nanoseconds
|
|
since 1970 should now accept a time.Time. Especially as a replacement
|
|
for the int64s, the type is good documentation about the meaning of
|
|
its value.
|
|
|
|
Whether you were previously calling time.Seconds, time.Nanoseconds,
|
|
time.LocalTime, or time.UTC, the replacement is the new function
|
|
time.Now.
|
|
|
|
If you previously wrote code like:
|
|
|
|
t0 := time.Nanoseconds()
|
|
myFunction()
|
|
t1 := time.Nanoseconds()
|
|
delta := t1 - t0
|
|
fmt.Printf("That took %.2f seconds\n", float64(t1-t0)/1e9)
|
|
|
|
you can now write:
|
|
|
|
t0 := time.Now()
|
|
myFunction()
|
|
t1 := time.Now()
|
|
delta := t1.Sub(t0)
|
|
fmt.Printf("That took %s\n", delta)
|
|
|
|
In this snippet, the variable delta is of the new type time.Duration, the
|
|
replacement for the many int64 parameters that were nanosecond
|
|
counts (but not since 1970).
|
|
|
|
Gofix can do the above conversions and some others, but it does not
|
|
rewrite explicit int64 types as time.Time. It is very likely that you will
|
|
need to edit your program to change these types after running gofix.
|
|
As always, be sure to read the changes that gofix makes using your
|
|
version control system's diff feature.
|
|
|
|
See http://weekly.golang.org/pkg/time/ for details.
|
|
|
|
In package os, the FileInfo struct is replaced by a FileInfo interface,
|
|
admitting implementations by code beyond the operating system.
|
|
Code that refers to *os.FileInfo (a pointer to the old struct) should
|
|
instead refer to os.FileInfo (the new interface).
|
|
The interface has just a few methods:
|
|
|
|
type FileInfo interface {
|
|
Name() string // base name of the file
|
|
Size() int64 // length in bytes
|
|
Mode() FileMode // file mode bits
|
|
ModTime() time.Time // modification time
|
|
IsDir() bool // abbreviation for Mode().IsDir()
|
|
}
|
|
|
|
If you need access to the underlying stat_t provided by the operating
|
|
system kernel, you can access it by assuming that the FileInfo you are
|
|
holding is actually an *os.FileStat, and that it's Sys field is actually a
|
|
*syscall.Stat_t, as in:
|
|
|
|
dev := fi.(*os.FileStat).Sys.(*syscall.Stat_t).Dev
|
|
|
|
Of course, this is not necessarily portable across different operating
|
|
systems.
|
|
|
|
Gofix will take care of rewriting *os.FileInfo to os.FileInfo for you,
|
|
and it will also rewrite expressions like fi.Name into calls like fi.Name().
|
|
|
|
See http://weekly.golang.org/pkg/os/#FileInfo for details.
|
|
|
|
The template package has been changed to export a new, simpler API.
|
|
The Set type is gone. Instead, templates are automatically associated by
|
|
being parsed together; nested definitions implicitly create associations.
|
|
Only associated templates can invoke one another.
|
|
This approach dramatically reduces the breadth of the construction API.
|
|
The html/template package has been updated also.
|
|
There's a gofix for the simplest and most common uses of the old API.
|
|
Code that doesn't mention the Set type is likely to work after running gofix;
|
|
code that uses Set will need to be updated by hand.
|
|
The template definition language itself is unchanged.
|
|
|
|
See http://weekly.golang.org/pkg/text/template/ for details.

This snapshot includes some language changes.
|
|
|
|
Map and function value comparisons are now disallowed (except for comparison
|
|
with nil) as per the Go 1 plan. Function equality was problematic in some
|
|
contexts and map equality compares pointers, not the maps' content.
|
|
|
|
As an experiment, structs are now allowed to be copied even if they contain
|
|
unexported fields. This gives packages the ability to return opaque values in
|
|
their APIs.
|
|
|
|

This weekly snapshot includes some package changes.
|
|
|
|
In preparation for the Go 1 package reorganziation the sources for various
|
|
packages have been moved, but the import paths remain unchanged. This
|
|
inconsistency breaks goinstall at this snapshot. If you use goinstall, please
|
|
stay synced to the previous weekly snapshot until the next one is tagged.
|
|
|
|
The Error methods in the html, bzip2, and sql packages that return error values
|
|
have been renamed to Err.
|
|
|
|
Some non-core parts of the http package have been moved to net/http/httputil.
|
|
The Dump* and NewChunked* functions and ClientConn, ServerConn, and
|
|
ReverseProxy types have been moved from http to httputil.
|
|
|
|
The API for html/template is now a direct copy of the template API, instead of
|
|
exposing a single Escape function. For HTML templates, use the
|
|
html/template package as you would the template package.
|
|
|

<h2 id="2011-11-02">2011-11-02 (new error type)</h2>
|
|
|
|
<pre>
|
|
This snapshot introduces the built-in error type, defined as
|
|
|
|
type error interface {
|
|
Error() string
|
|
}
|
|
|
|
The error type replaces os.Error. Notice that the method name has changed from
|
|
String to Error. Package fmt's Print formats both Stringers and errors:
|
|
in general there is no need to implement both String and Error methods.
|
|
|
|
Gofix can update most code. If you have split your package across many files,
|
|
it may help to use the -force=error command-line option, which forces gofix to
|
|
apply the error fix even if it is not obvious that a particular file needs it.
|
|
As always, it is a good idea to read and test the changes that gofix made
|
|
before committing them to your version control system.

<h2 id="2011-10-26">2011-10-26 (new rune type)</h2>
|
|
|
|
<pre>
|
|
This snapshot introduces the rune type, an alias for int that
|
|
should be used for Unicode code points.
|
|
|
|
A future release of Go (after Go 1) will change rune to be an
|
|
alias for int32 instead of int. Using rune consistently is the way
|
|
to make your code build both before and after this change.
|
|
|
|
To test your code for rune safety, you can rebuild the Go tree with
|
|
|
|
GOEXPERIMENT=rune32 ./all.bash
|
|
|
|
which builds a compiler in which rune is an alias for int32 instead of int.
|
|
|
|
Also, run govet on your code to identify methods that might need to have their
|
|
signatures updated.

|
|
This weekly snapshot includes some language and package changes that may
|
|
require code changes. Please read these notes carefully, as there are many
|
|
changes and your code will likely be affected.
|
|
|
|
The syntax for map deletion has been changed. Code that looks like:
|
|
m[x] = 0, false
|
|
should be written as:
|
|
delete(m, x)
|
|
The compiler still accepts m[x] = 0, false for now; even so, you can use gofix
|
|
to rewrite such assignments into delete(m, x).
|
|
|
|
The Go compiler will reject a return statement without arguments when any of
|
|
the result variables has been shadowed. Code rejected as a result of this
|
|
change is likely to be buggy.
|
|
|
|
Receive-only channels (<-chan T) cannot be closed.
|
|
The compiler will diagnose such attempts.
|
|
|
|
The first element of a map iteration is chosen at random. Code that depends on
|
|
iteration order will need to be updated.
|
|
|
|
Goroutines may be run during program initialization.
|
|
|
|
A string may be appended to a byte slice. This code is now legal:
|
|
var b []byte
|
|
var s string
|
|
b = append(b, s...)
|
|
|
|
The gotry command and its associated try package have been deleted.
|
|
It was a fun experiment that - in the end - didn't carry its weight.
|
|
|
|
The gotype tool has been moved to exp/gotype and its associated go/types
|
|
package has been moved to exp/types. The deprecated go/typechecker package has
|
|
been deleted.
|
|
|
|
The enbflint tool has been moved to pkg/exp/ebnflint and its associated ebnf
|
|
package has been moved to pkg/exp/ebnf.
|
|
|
|
The netchan package has been moved to old/netchan.
|
|
|
|
The http/spdy package has been moved to exp/spdy.
|
|
|
|
The exp/datafmt package has been deleted.
|
|
|
|
The container/vector package has been deleted. Slices are better:
|
|
http://code.google.com/p/go-wiki/wiki/SliceTricks
|
|
|

|
|
|
The math package's Fabs, Fdim, Fmax, Fmin and Fmod functions
|
|
have been renamed to Abs, Dim, Max, Min, and Mod.
|
|
|
|
Parts of the image package have been moved to the new image/color package.
|
|
The spin-off renames some types. The new names are simply better:
|
|
image.Color -> color.Color
|
|
image.ColorModel -> color.Model
|
|
image.ColorModelFunc -> color.ModelFunc
|
|
image.PalettedColorModel -> color.Palette
|
|
image.RGBAColor -> color.RGBA
|
|
image.RGBAColorModel -> color.RGBAModel
|
|
image.RGBA64Color -> color.RGBA64
|
|
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
|
|
ycbcr.YCbCrImage types will eventually migrate to color.YCbCr and image.YCbCr,
|
|
at a later date.

|
This weekly snapshot includes changes to the image, path/filepath, and time
|
|
packages. Code that uses these packages may need to be updated.
|
|
|
|
The image package's NewX functions (NewRGBA, NewNRGBA, etc) have been changed
|
|
to take a Rectangle argument instead of a width and height.
|
|
Gofix can make these changes automatically.
|
|
|
|
The path/filepath package's Walk function has been changed to take a WalkFunc
|
|
function value instead of a Visitor interface value. WalkFunc is like the
|
|
Visitor's VisitDir and VisitFile methods except it handles both files and
|
|
directories:
|
|
func(path string, info *os.FileInfo, err os.Error) os.Error
|
|
To skip walking a directory (like returning false from VisitDir) the WalkFunc
|
|
must return SkipDir.
|
|
|
|
The time package's Time struct's Weekday field has been changed to a method.
|
|
The value is calculated on demand, avoiding the need to re-parse
|
|
programmatically-constructed Time values to find the correct weekday.
|
|
|
|
There are no gofixes for the filepath or time API changes, but instances of the
|
|
old APIs will be caught by the compiler. The Weekday one is easy to update by
|
|
hand. The Walk one may take more consideration, but will have fewer instances
|
|
to fix.
|
|
|
|
* build: add build comments to core packages.
|
|
* codereview: Mercurial 1.9 fix for hg diff @nnn.
|
|
* crypto/tls: handle non-TLS more robustly,
|
|
support SSLv3.

|
|
* godoc: show packages matching a query at the top,
|
|
support for complete index serialization,
|
|
use go/build to find files in a package.
|
|
* gofmt: accept program fragments on standard input, add else test.
|
|
* http/cgi: add openbsd environment configuration.
|
|
* http: document that Response.Body is non-nil.
|
|

|
|
* json: if a field's tag is "-", ignore the field for encoding and decoding.
|
|
* ld: grow dwarf includestack on demand.
|
|
* net, syscall: implement SetsockoptIPMReq(), and
|
|
move to winsock v2.2 for multicast support (thanks Paul Lalonde).
|
|
* net: add a LookupTXT function.
|
|
* os: os.RemoveAll to check for wboth error codes on Windows (thanks Jaroslavas Počepko).
|
|
* path/filepath: fix Visitor doc (thanks Gustavo Niemeyer),
|
|
make UNC file names work (thanks Yasuhiro Matsumoto).
|
|
* runtime: optimizations to channels on Windows (thanks Hector Chu),
|

|
|
* sync/atomic: add 64-bit Load and Store.

|
* syscall: add route flags for linux (thanks Mikio Hara).
|
|
* test: add test for inheriting private method from anonymous field.

|
rename websocket.WebSocketAddr to *websocket.Addr.

This weekly contains performance improvements and bug fixes.
|
|
|
|
The gc compiler now does escape analysis, which improves program performance
|
|
by placing variables on the call stack instead of the heap when it is safe to
|

do so.

|
|
This weekly contains some package re-shuffling. Users of the http and
|
|
template packages may be affected.
|
|
|
|
This weekly replaces the template package with exp/template.
|
|
The original template package is still available as old/template.
|
|
The old/template package is deprecated and will be removed at some point
|
|
in the future. The Go tree has been updated to use the new template package.
|
|
We encourage users of the old template package to switch to the new one.
|
|
Code that uses template or exp/template will need to change
|
|
its import lines to "old/template" or "template", respectively.
|
|
|
|
The http package's URL parsing and query escaping code (such as ParseURL and
|
|
URLEscape) has been moved to the new url package, with several simplifications
|
|
to the names. Client code can be updated automatically with gofix.
|
|
|
|
* asn1: support unmarshaling structs with int32 members (thanks Dave Cheney).
|
|
* build: allow builds without cgo or hg,
|
|
support versioning without hg (thanks Gustavo Niemeyer).
|
|

|
|
* cgo: omit duplicate symbols in writeDefs (thanks Julian Phillips).
|
|
* misc: add support for OpenBSD.

|
|
This weekly snapshot includes a language change and a change to the image
|
|
package that may require changes to client code.
|
|
|
|
The language change is that an "else" block is now required to have braces
|
|
except if the body of the "else" is another "if". Since gofmt always puts those
|
|
braces in anyway, programs will not be affected unless they contain "else for",
|
|
"else switch", or "else select". Run gofmt to fix any such programs.
|
|
|
|
The image package has had significant changes made to the Pix field of struct
|
|
types such as image.RGBA and image.NRGBA. The image.Image interface type has
|
|
not changed, though, and you should not need to change your code if you don't
|
|
explicitly refer to Pix fields. For example, if you decode a number of images
|
|
using the image/jpeg package, compose them using image/draw, and then encode
|
|
the result using image/png, then your code should still work as before.
|
|
|
|
If you do explicitly refer to Pix fields, there are two changes. First, Pix[0]
|
|
now refers to the pixel at Bounds().Min instead of the pixel at (0, 0). Second,
|
|
the element type of the Pix slice is now uint8 instead of image.FooColor. For
|
|
example, for an image.RGBA, the channel values will be packed R, G, B, A, R, G,
|
|
B, A, etc. For 16-bits-per-channel color types, the pixel data will be stored
|
|
as big-endian uint8s.
|
|
|
|
Most Pix field types have changed, and so if your code still compiles after
|
|
this change, then you probably don't need to make any further changes (unless
|
|
you use an image.Paletted's Pix field). If you do get compiler errors, code
|
|
that used to look like this:
|
|
|
|
// Get the R, G, B, A values for the pixel at (x, y).
|
|
var m *image.RGBA = loadAnImage()
|
|
c := m.Pix[y*m.Stride + x]
|
|
r, g, b, a := c.R, c.G, c.B, c.A
|
|
|
|
should now look like this:
|
|
|
|
// Get the R, G, B, A values for the pixel at (x, y).
|
|
var m *image.RGBA = loadAnImage()
|
|
i := (y-m.Rect.Min.Y)*m.Stride + (x-m.Rect.Min.X)*4
|
|
r := m.Pix[i+0]
|
|
g := m.Pix[i+1]
|
|
b := m.Pix[i+2]
|
|
a := m.Pix[i+3]
|
|
|
|
This image package change will not be fixed by gofix: how best to translate
|
|
code into something efficient and idiomatic depends on the surrounding context,
|
|
and is not easily automatable. Examples of what to do can be found in the
|
|
changes to image/draw/draw.go in http://codereview.appspot.com/4675076/

This weekly snapshot includes changes to the strings, http, reflect, json, and
|
|
xml packages. Code that uses these packages will need changes. Most of these
|
|
changes can be made automatically with gofix.
|
|
|
|
The strings package's Split function has itself been split into Split and
|
|
SplitN. SplitN is the same as the old Split. The new Split is equivalent to
|
|
SplitN with a final argument of -1.
|
|
|
|
The http package has a new FileSystem interface that provides access to files.
|
|
The FileServer helper now takes a FileSystem argument instead of an explicit
|
|
file system root. By implementing your own FileSystem you can use the
|
|
FileServer to serve arbitrary data.
|
|
|
|
The reflect package supports a new struct tag scheme that enables sharing of
|
|
struct tags between multiple packages.
|
|
In this scheme, the tags must be of the form:
|
|
key:"value" key2:"value2"
|
|
reflect.StructField's Tag field now has type StructTag (a string type), which
|
|
has method Get(key string) string that returns the associated value.
|
|
Clients of json and xml will need to be updated. Code that says
|
|
type T struct {
|
|
X int "name"
|
|
}
|
|
should become
|
|
type T struct {
|
|
X int `json:"name"` // or `xml:"name"`
|
|
}
|
|
Use govet to identify struct tags that need to be changed to use the new syntax.
|
|
|
|

|
|

This snapshot includes a language change that restricts the use of goto.
|
|
In essence, a "goto" statement outside a block cannot jump to a label inside
|
|
that block. Your code may require changes if it uses goto.
|
|
This changeset shows how the new rule affected the Go tree:
|
|
http://code.google.com/p/go/source/detail?r=dc6d3cf9279d
|
|
|
|
The os.ErrorString type has been hidden. If your code uses os.ErrorString it
|
|
must be changed. Most uses of os.ErrorString can be replaced with os.NewError.
|
|
|
|
Other changes:
|
|
* 5c: do not use R9 and R10.
|
|
* 8l: more fixes for Plan 9 (thanks Lucio De Re).

This snapshot includes changes to the strconv, http, and exp/draw packages.
|
|
Client code that uses the http or exp/draw packages will need to be changed,
|
|
and code that uses strconv or fmt's "%q" formatting directive merits checking.
|
|
|
|
The strconv package's Quote function now escapes only those Unicode code points
|
|
not classified as printable by unicode.IsPrint. Previously Quote would escape
|
|
all non-ASCII characters. This also affects the fmt package's "%q" formatting
|
|
directive. The previous quoting behavior is still available via strconv's new
|
|
QuoteToASCII function.
|
|
|
|
Most instances of the type map[string][]string in the http package have been
|
|
replaced with the new Values type. The http.Values type has the Get, Set, Add,
|
|
and Del helper methods to make working with query parameters and form values
|
|
more convenient.
|
|
|
|
The exp/draw package has been split into the image/draw and exp/gui packages.
|
|
|
|

This snapshot includes changes to the exec package that will require changes
|
|
to client code.
|
|
|
|
The exec package has been re-designed with a more convenient and succinct API.
|
|
This code:
|
|
args := []string{"diff", "-u", "file1.txt", "file2.txt"}
|
|
p, err := exec.Run("/usr/bin/diff", args, os.Environ(), "",
|
|
exec.DevNull, exec.Pipe, exec.DevNull)
|
|
if err != nil {
|
|
return nil, err
|
|
}
|
|
var buf bytes.Buffer
|
|
io.Copy(&buf, p.Stdout)
|
|
w, err := p.Wait(0)
|
|
p.Close()
|
|
if err != nil {
|
|
return nil, err
|
|
}
|
|
return buf.Bytes(), err
|
|
can be rewritten as:
|
|
return exec.Command("diff", "-u", "file1.txt", "file2.txt").Output()
|
|
See the exec package documentation for the details ("godoc exec").
|
|
|
|
By setting the GOPATH environment variable you can use goinstall to build and
|
|
install your own code and external libraries outside of the Go tree (and avoid
|
|
writing Makefiles).
|
|
See the goinstall command documentation for the details ("godoc goinstall").
|
|
|

This snapshot includes changes to the http package that will require changes to
|
|
client code.
|
|
|
|
The finalURL return value of the Client.Get method has been removed.
|
|
This value is now accessible via the new Request field on http.Response.
|
|
For example, this code:
|
|
|
|
res, finalURL, err := http.Get(...)
|
|
|
|
should be rewritten as:
|
|
|
|
res, err := http.Get(...)
|
|
if err != nil {
|
|
// ...
|
|
}
|
|
finalURL := res.Request.URL.String()
|
|
|
|
Uses of http.Get that assign the finalURL value to _ can be rewritten
|
|
automatically with gofix.
|
|
|
|
This snapshot also includes an optimization to the append function that makes it
|
|
between 2 and 5 times faster in typical use cases.

efficient, after the last weekly's major API update. If your code uses reflect
|
|
it may require further changes, not all of which can be made automatically by
|
|
gofix. For the full details of the change, see

weekly.2011-04-13

|
|
This weekly snapshot includes major changes to the reflect package and the
|
|
os.Open function. Code that uses reflect or os.Open will require updating,
|
|
which can be done mechanically using the gofix tool.
|
|
|
|
The reflect package's Type and Value types have changed. Type is now an
|
|
interface that implements all the possible type methods. Instead of a type
|
|
switch on a reflect.Type t, switch on t.Kind(). Value is now a struct value
|
|
that implements all the possible value methods. Instead of a type switch on a
|
|
reflect.Value v, switch on v.Kind(). See the change for the full details:
|
|
http://code.google.com/p/go/source/detail?r=843855f3c026
|
|
|
|
The os package's Open function has been replaced by three functions:
|
|
OpenFile(name, flag, perm) // same as old Open
|
|
Open(name) // same as old Open(name, O_RDONLY, 0)
|
|
Create(name) // same as old Open(name, O_RDWR|O_TRUNC|O_CREAT, 0666)
|
|
|
|
To update your code to use the new APIs, run "gofix path/to/code". Gofix can't
|
|
handle all situations perfectly, so read and test the changes it makes before
|
|
committing them.
|
|
|
|
Other changes:
|
|
* archive/zip: add func OpenReader, type ReadCloser (thanks Dmitry Chestnykh).

This snapshot includes changes to the net package. Your code will require
|
|
changes if it uses the Dial or LookupHost functions.
|
|
|
|
The laddr argument has been removed from net.Dial, and the cname return value
|
|
has been removed from net.LookupHost. The new net.LookupCNAME function can be
|
|
used to find the canonical host for a given name. You can update your

|
networking code with gofix.
|
|
|
|

This weekly release includes improved support for testing.
|
|
|
|
Memory and CPU profiling is now available via the gotest tool. Gotest will
|
|
produce memory and CPU profiling data when invoked with the -test.memprofile
|
|
and -test.cpuprofile flags. Run "godoc gotest" for details.
|
|
|
|
We have also introduced a way for tests to run quickly when an exhaustive test
|
|
is unnecessary. Gotest's new -test.short flag in combination with the testing
|
|
package's new Short function allows you to write tests that can be run in
|
|
normal or "short" mode; short mode is now used by all.bash to reduce
|
|
installation time.
|
|
The Makefiles know about the flag - you can just run "make testshort".

This week's release introduces a new release tagging scheme. We intend to
|
|
continue with our weekly releases, but have renamed the existing tags from
|
|
"release" to "weekly". The "release" tag will now be applied to one hand-picked
|
|
stable release each month or two.
|
|
|
|
The revision formerly tagged "release.2011-03-07.1" (now "weekly.2011-03-07.1")
|
|
has been nominated our first stable release, and has been given the tag
|
|
"release.r56". As we tag each stable release we will post an announcement to
|
|
the new golang-announce mailing list:
|
|
http://groups.google.com/group/golang-announce
|
|
|
|
You can continue to keep your Go installation updated using "hg update
|
|
release", but now you should only need to update once we tag a new stable
|
|
release, which we will announce here. If you wish to stay at the leading edge,
|
|
you should switch to the weekly tag with "hg update weekly".
|
|
|
|
|
|
This weekly release includes significant changes to the language spec and the
|
|
http, os, and syscall packages. Your code may need to be changed. It also
|
|
introduces the new gofix tool.
|
|
|
|
The closed function has been removed from the language. The syntax for channel
|
|
receives has been changed to return an optional second value, a boolean value
|
|
indicating whether the channel is closed. This code:
|
|
v := <-ch
|
|
if closed(ch) {
|
|
// channel is closed
|
|
}
|
|
should now be written as:
|
|
v, ok := <-ch
|
|
if !ok {
|
|
// channel is closed
|
|
}
|
|
|
|
It is now illegal to declare unused labels, just as it is illegal to declare
|
|
unused local variables.
|
|
|
|
The new gofix tool finds Go programs that use old APIs and rewrites them to use
|
|
newer ones. After you update to a new Go release, gofix helps make the
|
|
necessary changes to your programs. Gofix will handle the http, os, and syscall
|
|
package changes described below, and we will update the program to keep up with
|
|
future changes to the libraries.
|
|
|
|
The Hijack and Flush methods have been removed from the http.ResponseWriter
|
|
interface and are accessible via the new http.Hijacker and http.Flusher
|
|
interfaces. The RemoteAddr and UsingTLS methods have been moved from
|
|
http.ResponseWriter to http.Request.
|
|
|
|
The http.ResponseWriter interface's SetHeader method has been replaced by a
|
|
Header() method that returns the response's http.Header. Caller code needs to
|
|
change. This code:
|
|
rw.SetHeader("Content-Type", "text/plain")
|
|
should now be written as:
|
|
rw.Header().Set("Content-Type", "text/plain")

|
The os and syscall packages' StartProcess functions now take their final three
|
|
arguments as an *os.ProcAttr and *syscall.ProcAttr values, respectively. This
|
|
code:
|
|
os.StartProcess(bin, args, env, dir, fds)
|
|
should now be written as:
|
|
os.StartProcess(bin, args, &os.ProcAttr{Files: fds, Dir: dir, Env: env})
|
|
|
|
The gob package will now encode and decode values of types that implement the
|
|
gob.GobEncoder and gob.GobDecoder interfaces. This allows types with unexported
|
|
fields to transmit self-consistent descriptions; one instance is big.Int and
|
|
big.Rat.
|
|
|
|

This release includes changes to the http package and a small language change.
|
|
Your code will require changes if it manipulates http Headers or omits the
|
|
condition in if statements.
|
|
|
|
The new http.Header type replaces map[string]string in the Header and Trailer
|
|
fields of http.Request and http.Response.
|
|
A Header value can be manipulated via its Get, Set, Add, and Del methods.
|
|
See http://golang.org/pkg/http/#Header
|
|
|
|
The condition is now mandatory in if statements.
|
|
Previously it would default to true, as in switch and for statements.
|
|
This code is now illegal:
|
|
if x := foo(); {
|
|
// code that is always executed
|
|
}
|
|
The same effect can be achieved like this:
|
|
if x := foo(); true {
|
|
// code
|
|
}
|
|
Or, in a simpler form:
|
|
{
|
|
x := foo()
|
|
// code
|
|
}
|
|
|
|

<pre>
|
|
This release includes significant changes to channel operations and minor
|
|
changes to the log package. Your code will require modification if it uses
|
|
channels in non-blocking communications or the log package's Exit functions.
|
|
|
|
Non-blocking channel operations have been removed from the language.
|
|
The equivalent operations have always been possible using a select statement
|
|
with a default clause. If a default clause is present in a select, that clause
|
|
will execute (only) if no other is ready, which allows one to avoid blocking on
|
|
a communication.
|
|
|
|
For example, the old non-blocking send operation,
|
|
|
|
if ch <- v {
|
|
// sent
|
|
} else {
|
|
// not sent
|
|
}
|
|
|
|
should be rewritten as,
|
|
|
|
select {
|
|
case ch <- v:
|
|
// sent
|
|
default:
|
|
// not sent
|
|
}
|
|
|
|
Similarly, this receive,
|
|
|
|
v, ok := <-ch
|
|
if ok {
|
|
// received
|
|
} else {
|
|
// not received
|
|
}
|
|
|
|
should be rewritten as,
|
|
|
|
select {
|
|
case v := <-ch:
|
|
// received
|
|
default:
|
|
// not received
|
|
}
|
|
|
|
This change is a prelude to redefining the 'comma-ok' syntax for a receive.
|
|
In a later release, a receive expression will return the received value and an
|
|
optional boolean indicating whether the channel has been closed. These changes
|
|
are being made in two stages to prevent this semantic change from silently
|
|
breaking code that uses 'comma-ok' with receives.
|
|
There are no plans to have a boolean expression form for sends.
|
|
|
|
Sends to a closed channel will panic immediately. Previously, an unspecified
|
|
number of sends would fail silently before causing a panic.
|
|
|
|
The log package's Exit, Exitf, and Exitln functions have been renamed Fatal,
|
|
Fatalf, and Fatalln respectively. This brings them in line with the naming of
|
|
the testing package.
|
|
|
|
The port to the "tiny" operating system has been removed. It is unmaintained
|
|
and untested. It was a toy to show that Go can run on raw hardware and it
|
|
served its purpose. The source code will of course remain in the repository
|
|
history, so it could be brought back if needed later.
|
|
|
|
This release also changes some of the internal structure of the memory
|
|
allocator in preparation for other garbage collector changes.
|
|
If you run into problems, please let us know.
|
|
There is one known issue that we are aware of but have not debugged yet:
|
|
http://code.google.com/p/go/issues/detail?id=1464&.
|
|
|
|
Other changes in this release:
|
|
* 5l: document -F, force it on old ARMs (software floating point emulation)

This release removes the float and complex types from the language.
|
|
|
|
The default type for a floating point literal is now float64, and
|
|
the default type for a complex literal is now complex128.
|
|
|
|
Existing code that uses float or complex must be rewritten to
|
|
use explicitly sized types.
|
|
|
|
The two-argument constructor cmplx is now spelled complex.

The json, gob, and template packages have changed, and code that uses them
|
|
may need to be updated after this release. They will no longer read or write
|
|
unexported struct fields. When marshaling a struct with json or gob the
|
|
unexported fields will be silently ignored. Attempting to unmarshal json or
|
|
gob data into an unexported field will generate an error. Accessing an
|
|
unexported field from a template will cause the Execute function to return
|
|
an error.
|
|
|
|
Godoc now supports regular expression full text search, and this
|
|
functionality is now available on golang.org.

<pre>
|
|
Package crypto/cipher has been started, to replace crypto/block.
|
|
As part of the changes, rc4.Cipher's XORKeyStream method signature has changed from
|
|
XORKeyStream(buf []byte)
|
|
to
|
|
XORKeyStream(dst, src []byte)
|
|
to implement the cipher.Stream interface. If you use crypto/block, you'll need
|
|
to switch to crypto/cipher once it is complete.
|
|
|
|
Package smtp's StartTLS now takes a *tls.Config argument.
|
|
|
|
Package reflect's ArrayCopy has been renamed to Copy. There are new functions
|
|
Append and AppendSlice.
|
|
|
|
The print/println bootstrapping functions now write to standard error.
|
|
To write to standard output, use fmt.Print[ln].
|
|
|
|
A new tool, govet, has been added to the Go distribution. Govet is a static
|
|
checker for Go programs. At the moment, and for the foreseeable future,
|
|
it only checks arguments to print calls.
|
|
|
|
The cgo tool for writing Go bindings for C code has changed so that it no
|
|
longer uses stub .so files (like cgo_stdio.so). Cgo-based packages using the
|
|
standard Makefiles should build without any changes. Any alternate build
|
|
mechanisms will need to be updated.
|
|
|
|
The C and Go compilers (6g, 6c, 8g, 8c, 5g, 5c) now align structs according to
|
|
the maximum alignment of the fields they contain; previously they aligned
|
|
structs to word boundaries. This may break non-cgo-based code that attempts to
|
|
mix C and Go.
|
|
|
|
NaCl support has been removed. The recent linker changes broke NaCl support
|
|
a month ago, and there are no known users of it.
|
|
If necessary, the NaCl code can be recovered from the repository history.
|
|
|
|
* 5g/8g, 8l, ld, prof: fix output of 32-bit values (thanks Eoghan Sherry).
|
|
* [68]l and runtime: GDB support for interfaces and goroutines.
|
|
* 6l, 8l: support for linking ELF and Mach-O .o files.

|
|
* codereview: keep quiet when not in use (thanks Eoghan Sherry).
|
|
* compress/flate: implement Flush, equivalent to zlib's Z_SYNC_FLUSH.
|
|
* crypto/tls: use rand.Reader in cert generation example (thanks Anthony Martin).
|
|
* dashboard: fix project tag filter.
|
|
* debug/elf, debug/macho: add ImportedLibraries, ImportedSymbols.
|
|
* doc/go_mem: goroutine exit is not special.
|
|
* event.go: another print glitch from gocheck.
|
|
* gc: bug fixes,
|
|
syntax error for incomplete chan type (thanks Ryan Hitchman).
|
|
* go/ast: fix ast.Walk.
|
|
* gob: document the byte count used in the encoding of values,
|
|
fix bug sending zero-length top-level slices and maps,
|
|
Register should use the original type, not the indirected one.
|
|
* godashboard: support submitting projects with non-ascii names (thanks Ryan Hitchman)
|
|
* godefs: guard against structs with pad fields
|
|
* godoc: added textual search, to enable use -fulltext flag.
|
|
* gofmt: simplify "x, _ = range y" to "x = range y".
|
|
* gopack: allow ELF/Mach-O objects in .a files without clearing allobj.
|
|
* go/token,scanner: fix comments so godoc aligns properly.
|
|
* govet: on error continue to the next file (thanks Christopher Wedgwood).
|
|
* html: improved parsing.
|
|

|
|
reading of ELF object files,
|
|
reading of Mach-O object files.

|
|
rename the MinFloat constant to SmallestNonzeroFloat.
|
|

|
|
* os: fix test of RemoveAll.
|
|
* os/inotify: new package (thanks Balazs Lecz).
|
|
* os: make MkdirAll work with symlinks (thanks Ryan Hitchman).
|
|
* regexp: speed up by about 30%; also simplify code for brackets.
|
|
* runtime/linux/386: set FPU to 64-bit precision.
|
|
* runtime: remove paranoid mapping at 0.
|
|
* suffixarray: add Bytes function.
|
|
* syscall: add network interface constants for linux/386, linux/amd64 (thanks Mikio Hara).
|
|

This release includes some package changes. If you use the crypto/tls or
|
|
go/parser packages your code may require changes.
|
|
|
|
The crypto/tls package's Dial function now takes an additional *Config
|
|
argument. Most uses will pass nil to get the same default behavior as before.
|
|
See the documentation for details:
|
|
http://golang.org/pkg/crypto/tls/#Config
|
|
http://golang.org/pkg/crypto/tls/#Dial
|
|
|
|
The go/parser package's ParseFile function now takes a *token.FileSet as its
|
|
first argument. This is a pointer to a data structure used to store
|
|
position information. If you don't care about position information you
|
|
can pass "token.NewFileSet()". See the documentation for details:
|
|
http://golang.org/pkg/go/parser/#ParseFile
|
|
|
|
This release also splits the patent grant text out of the LICENSE file into a
|
|
separate PATENTS file and changes it to be more like the WebM grant.
|
|
These clarifications were made at the request of the Fedora project.
|
|
|
|
Other changes:
|
|
* [68]l: generate debug info for builtin structured types, prettyprinting in gdb.
|
|
* 8l: add dynimport to import table in Windows PE (thanks Wei Guangjing).
|
|

|
|
* all: fix broken calls to Printf etc.
|
|
* bufio: make Reader.Read implement io.Reader semantics (thanks Roger Peppe).
|
|

|
|

|
|
Several package changes in this release may require you to update your code if
|
|
you use the bytes, template, or utf8 packages. In all cases, any outdated code
|
|
will fail to compile rather than behave erroneously.
|
|
|
|
The bytes package has changed. Its Add and AddByte functions have been removed,
|
|
as their functionality is provided by the recently-introduced built-in function
|
|
"append". Any code that uses them will need to be changed:
|
|
s = bytes.Add(s, b) -> s = append(s, b...)
|
|
s = bytes.AddByte(b, c) -> s = append(s, b)
|
|
s = bytes.Add(nil, c) -> append([]byte(nil), c)
|
|
|
|
The template package has changed. Your code will need to be updated if it calls
|
|
the HTMLFormatter or StringFormatter functions, or implements its own formatter
|
|
functions. The function signature for formatter types has changed to:
|
|
func(wr io.Writer, formatter string, data ...interface{})
|
|
to allow multiple arguments to the formatter. No templates will need updating.
|
|
See the change for examples:
|
|
http://code.google.com/p/go/source/detail?r=2c2be793120e
|
|
|
|
The template change permits the implementation of multi-word variable
|
|
instantiation for formatters. Before one could say
|
|
{field}
|
|
or
|
|
{field|formatter}
|
|
Now one can also say
|
|
{field1 field2 field3}
|
|
or
|
|
{field1 field2 field3|formatter}
|
|
and the fields are passed as successive arguments to the formatter,
|
|
by analogy to fmt.Print.
|
|
|
|
The utf8 package has changed. The order of EncodeRune's arguments has been
|
|
reversed to satisfy the convention of "destination first".
|
|
Any code that uses EncodeRune will need to be updated.
|
|
|
|
Other changes:
|
|
* [68]l: correct dwarf location for globals and ranges for arrays.
|
|
* big: fix (*Rat) SetFrac64(a, b) when b < 0 (thanks Eoghan Sherry).
|
|
* compress/flate: fix typo in comment (thanks Mathieu Lonjaret).
|
|
* crypto/elliptic: use a Jacobian transform for better performance.
|
|
* doc/code.html: fix reference to "gomake build" (thanks Anschel Schaffer-Cohen).
|
|
* doc/roadmap: update gdb status.
|
|
* doc/spec: fixed some omissions and type errors.
|
|
* doc: some typo fixes (thanks Peter Mundy).
|
|
* exp/eval: build fix for parser.ParseFile API change (thanks Anschel Schaffer-Cohen).
|
|
* fmt: Scan accepts Inf and NaN,
|
|
allow "% X" as well as "% x".

The birthday release includes a new Search capability inside the sort package.
|
|
It takes an unusual but very general and easy-to-use approach to searching
|
|
arbitrary indexable sorted data. See the documentation for details:
|
|
http://golang.org/pkg/sort/#Search
|
|
|
|
The ARM port now uses the hardware floating point unit (VFP). It still has a
|
|
few bugs, mostly around conversions between unsigned integer and floating-point
|
|
values, but it's stabilizing.
|
|
|
|
In addition, there have been many smaller fixes and updates:
|
|
|
|
* 6l: generate dwarf variable names with disambiguating suffix.
|
|
* container/list: make Remove return Value of removed element.
|
|
makes it easier to remove first or last item.
|
|
* crypto: add cast5 (default PGP cipher),
|
|
switch block cipher methods to be destination first.
|
|
* crypto/tls: use pool building for certificate checking
|
|
* go/ast: change embedded token.Position fields to named fields

* os: add Expand function to evaluate environment variables.
|
|
* path: add Glob (thanks Benny Siegert)
|
|
* runtime: memequal optimization (thanks Graham Miller)
|
|
prefix all external symbols with "runtime·" to avoid
|
|
conflicts linking with external C libraries.

*** This release changes the encoding used by package gob.
|
|
If you store gobs on disk, see below. ***
|
|
|
|
The ARM port (5g) now passes all tests. The optimizer is not yet enabled, and
|
|
floating point arithmetic is performed entirely in software. Work is underway
|
|
to address both of these deficiencies.
|
|
|
|
The syntax for arrays, slices, and maps of composite literals has been
|
|
simplified. Within a composite literal of array, slice, or map type, elements
|
|
that are themselves composite literals may elide the type if it is identical to
|
|
the outer literal's element type. For example, these expressions:
|
|
[][]int{[]int{1, 2, 3}, []int{4, 5}}
|
|
map[string]Point{"x": Point{1.5, -3.5}, "y": Point{0, 0}}
|
|
can be simplified to:
|
|
[][]int{{1, 2, 3}, {4, 5}}
|
|
map[string]Point{"x": {1.5, -3.5}, "y": {0, 0}}
|
|
Gofmt can make these simplifications mechanically when invoked with the
|
|
new -s flag.
|
|
|
|
The built-in copy function can now copy bytes from a string value to a []byte.
|
|
Code like this (for []byte b and string s):
|
|
for i := 0; i < len(s); i++ {
|
|
b[i] = s[i]
|
|
}
|
|
can be rewritten as:
|
|
copy(b, s)
|
|
|
|
The gob package can now encode and decode interface values containing types
|
|
registered ahead of time with the new Register function. These changes required
|
|
a backwards-incompatible change to the wire format. Data written with the old
|
|
version of the package will not be readable with the new one, and vice versa.
|
|
(Steps were made in this change to make sure this doesn't happen again.)
|
|
We don't know of anyone using gobs to create permanent data, but if you do this
|
|
and need help converting, please let us know, and do not update to this release
|
|
yet. We will help you convert your data.
|
|
|
|
Other changes:
|
|
* 5g, 6g, 8g: generate code for string index instead of calling function.
|
|
* 5l, 6l, 8l: introduce sub-symbols.
|
|
* 6l/8l: global and local variables and type info.
|
|
* Make.inc: delete unnecessary -fno-inline flag to quietgcc.
|
|
* arm: precise float64 software floating point, bug fixes.
|
|
* big: arm assembly, faster software mulWW, divWW.
|
|
* build: only print "You need to add foo to PATH" when needed.
|
|
* container/list: fix Remove bug and use pointer to self as identifier.
|
|
* doc: show page title in browser title bar,
|
|
update roadmap.
|
|
* encoding/binary: give LittleEndian, BigEndian specific types.
|
|
* go/parser: consume auto-inserted semi when calling ParseExpr().
|
|
* gobuilder: pass GOHOSTOS and GOHOSTARCH to build,
|
|
write build and benchmarking logs to disk.

|
|

|
|
* gotest: generate correct gofmt-formatted _testmain.go.
|
|
* image/png: speed up paletted encoding ~25% (thanks Brad Fitzpatrick).
|
|
* misc: update python scripts to specify python2 as python3 is now "python".
|
|
* net: fix comment on Dial to mention unix/unixgram.
|
|
* rpc: expose Server type to allow multiple RPC Server instances.
|

This release removes the log package's deprecated functions.
|
|
Code that has not been updated to use the new interface will break.
|
|
See the previous release notes for details:
|
|
http://golang.org/doc/devel/release.html#2010-10-13
|
|
|
|
Also included are major improvements to the linker. It is now faster,
|
|
uses less memory, and more parallelizable (but not yet parallel).
|
|
|
|
The nntp package has been removed from the standard library.
|
|
Its new home is the nntp-go project at Google Code:
|
|
http://code.google.com/p/nntp-go
|
|
You can install it with goinstall:
|
|
goinstall nntp-go.googlecode.com/hg/nntp
|
|
And import it in your code like so:
|
|
import "nntp-go.googlecode.com/hg/nntp"
|
|
|
|
Other changes:
|
|
* 6g: avoid too-large immediate constants.

This release includes changes to the log package, the removal of exp/iterable,
|
|
two new tools (gotry and goplay), one small language change, and many other
|
|
changes and fixes. If you use the log or iterable packages, you need to make
|
|
changes to your code.
|
|
|
|
The log package has changed. Loggers now have only one output, and output to
|
|
standard error by default. The names have also changed, although the old names
|
|
are still supported. They will be deleted in the next release, though, so it
|
|
would be good to update now if you can. For most purposes all you need to do
|
|
is make these substitutions:
|
|
log.Stderr -> log.Println or log.Print
|
|
log.Stderrf -> log.Printf
|
|
log.Crash -> log.Panicln or log.Panic
|
|
log.Crashf -> log.Panicf
|
|
log.Exit -> log.Exitln or log.Exit
|
|
log.Exitf -> log.Exitf (no change)
|
|
Calls to log.New() must drop the second argument.
|
|
Also, custom loggers with exit or panic properties will need to be reworked.
|
|
For full details, see the change description:
|
|
http://code.google.com/p/go/source/detail?r=d8a3c7563d
|
|
|
|
The language change is that uses of pointers to interface values no longer
|
|
automatically dereference the pointer. A pointer to an interface value is more
|
|
often a beginner's bug than correct code.
|
|
|
|
The package exp/iterable has been removed. It was an interesting experiment,
|
|
but it encourages writing inefficient code and has outlived its utility.
|
|
|
|
The new tools:
|
|
* gotry: an exercise in reflection and an unusual tool. Run 'gotry' for details.
|
|
* goplay: a stand-alone version of the Go Playground. See misc/goplay.
|
|
|
|
Other changes:
|
|
* 6l: Mach-O fixes, and fix to work with OS X nm/otool (thanks Jim McGrath).
|
|
* [568]a: correct line numbers for statements.
|
|
* arm: code generation and runtime fixes,
|
|
adjust recover for new reflect.call,
|
|
enable 6 more tests after net fix.
|
|
* big: fix panic and round correctly in Rat.FloatString (thanks Anthony Martin).
|
|
* build: Make.cmd: remove $(OFILES) (thanks Eric Clark),
|
|
Make.pkg: remove .so before installing new one,
|
|
add GOHOSTOS and GOHOSTARCH environment variables.
|
|
* crypto/tls: better error messages for certificate issues,
|
|
make SetReadTimeout work.
|
|
* doc: add Sydney University video,
|
|
add The Expressiveness of Go talk.
|
|
* exp/draw/x11: support X11 vendors other than "The X.Org Foundation".
|
|
* expvar: add (*Int).Set (thanks Sam Thorogood).
|
|
* fmt: add Errorf helper function,
|
|
allow %d on []byte.
|
|
* gc: O(1) string comparison when lengths differ,
|
|
various bug fixes.
|
|
* http: return the correct error if a header line is too long.
|
|
* image: add image.Tiled type, the Go equivalent of Plan 9's repl bit.
|
|
* ld: be less picky about bad line number info.
|
|
* misc/cgo/life: fix for new slice rules (thanks Graham Miller).
|
|
* net: allow _ in DNS names.
|
|
* netchan: export before import when testing, and
|
|
zero out request to ensure correct gob decoding. (thanks Roger Peppe).
|

|
|
correct iteration of large map values,
|
|
faster strequal, memequal (thanks Graham Miller),
|
|

|
|
add ucred structure for SCM_CREDENTIALS over UNIX sockets. (thanks Albert Strasheim).

|
This release includes some minor language changes and some significant package
|
|
changes. You may need to change your code if you use ...T parameters or the
|
|
http package.
|
|
|
|
The semantics and syntax of forwarding ...T parameters have changed.
|
|
func message(f string, s ...interface{}) { fmt.Printf(f, s) }
|
|
Here, s has type []interface{} and contains the parameters passed to message.
|
|
Before this language change, the compiler recognized when a function call
|
|
passed a ... parameter to another ... parameter of the same type, and just
|
|
passed it as though it was a list of arguments. But this meant that you
|
|
couldn't control whether to pass the slice as a single argument and you
|
|
couldn't pass a regular slice as a ... parameter, which can be handy. This
|
|
change gives you that control at the cost of a few characters in the call.
|
|
If you want the promotion to ..., append ... to the argument:
|
|
func message(f string, s ...interface{}) { fmt.Printf(f, s...) }
|
|
Without the ..., s would be passed to Printf as a single argument of type
|
|
[]interface{}. The bad news is you might need to fix up some of your code,
|
|
but the compiler will detect the situation and warn you.
|
|
|
|
Also, the http.Handler and http.HandlerFunc types have changed. Where http
|
|
handler functions previously accepted an *http.Conn, they now take an interface
|
|
type http.ResponseWriter. ResponseWriter implements the same methods as *Conn,
|
|
so in most cases the only change required will be changing the type signature
|
|
of your handler function's first parameter. See:
|
|
http://golang.org/pkg/http/#Handler
|
|
|
|
The utf8 package has a new type, String, that provides efficient indexing
|
|
into utf8 strings by rune (previously an expensive conversion to []int
|
|
was required). See:
|
|
http://golang.org/pkg/utf8/#String
|
|
|
|
The compiler will now automatically insert a semicolon at the end of a file if
|
|
one is not found. This effect of this is that Go source files are no longer
|
|
required to have a trailing newline.
|
|
|
|
Other changes:
|
|
* 6prof: more accurate usage message.
|
|
* archive/zip: new package for reading Zip files.
|
|
* arm: fix code generation, 10 more package tests pass.
|
|
* asn1: make interface consistent with json.
|
|
* bufio.UnreadRune: fix bug at EOF.
|
|
* build: clear custom variables like GREP_OPTIONS,
|
|

|
|

|
|
* doc: add to and consolidate non-english doc references,
|
|
consolidate FAQs into a single file, go_faq.html,
|
|
updates for new http interface.
|
|
* fmt/Printf: document and tweak error messages produced for bad formats.
|
|
* gc: allow select case expr = <-c,
|
|
eliminate duplicates in method table,
|
|
fix reflect table method receiver,
|
|
improve error message for x \= 0.
|
|
* go/scanner: treat EOF like a newline for purposes of semicolon insertion.
|
|
* gofmt: stability improvements.
|
|
* gotest: leave _testmain.go for "make clean" to clean up.

|
|
support HTTP/1.0 Keep-Alive.
|
|
* json: do not write to unexported fields.
|
|
* libcgo: don't build for NaCl,
|
|
set g, m in thread local storage for windows 386 (thanks Wei Guangjing).
|
|
* math: Fix off-by-one error in Ilogb and Logb. (thanks Charles L. Dorian).
|
|

This release includes changes to the build system that will likely require you
|
|
to make changes to your environment variables and Makefiles.
|
|
|
|
All environment variables are now optional:
|
|
- $GOOS and $GOARCH are now optional; their values should now be inferred
|
|
automatically by the build system,
|
|
- $GOROOT is now optional, but if you choose not to set it you must run
|
|
'gomake' instead of 'make' or 'gmake' when developing Go programs
|
|
using the conventional Makefiles,
|
|
- $GOBIN remains optional and now defaults to $GOROOT/bin;
|
|
if you wish to use this new default, make sure it is in your $PATH
|
|
and that you have removed the existing binaries from $HOME/bin.
|
|
|
|
As a result of these changes, the Go Makefiles have changed. If your Makefiles
|
|
inherit from the Go Makefiles, you must change this line:
|
|
include ../../Make.$(GOARCH)
|
|
to this:
|
|
include ../../Make.inc
|
|
|
|
This release also removes the deprecated functions in regexp and the
|
|
once package. Any code that still uses them will break.
|
|
See the notes from the last release for details:
|
|
http://golang.org/doc/devel/release.html#2010-08-11
|
|
|
|
Other changes:
|
|
* 6g: better registerization for slices, strings, interface values
|
|
* 6l: line number information in DWARF format

This release introduces some package changes. You may need to change your
|
|
code if you use the once, regexp, image, or exp/draw packages.
|
|
|
|
The type Once has been added to the sync package. The new sync.Once will
|
|
supersede the functionality provided by the once package. We intend to remove
|
|
the once package after this release. See:
|
|
http://golang.org/pkg/sync/#Once
|
|
All instances of once in the standard library have been replaced with
|
|
sync.Once. Reviewing these changes may help you modify your existing code.
|
|
The relevant changeset:
|
|
http://code.google.com/p/go/source/detail?r=fa2c43595119
|
|
|
|
A new set of methods has been added to the regular expression package, regexp.
|
|
These provide a uniformly named approach to discovering the matches of an
|
|
expression within a piece of text; see the package documentation for details:
|
|
http://golang.org/pkg/regexp/
|
|
These new methods will, in a later release, replace the old methods for
|
|
matching substrings. The following methods are deprecated:
|
|
Execute (use FindSubmatchIndex)
|
|
ExecuteString (use FindStringSubmatchIndex)
|
|
MatchStrings(use FindStringSubmatch)
|
|
MatchSlices (use FindSubmatch)
|
|
AllMatches (use FindAll; note that n<0 means 'all matches'; was n<=0)
|
|
AllMatchesString (use FindAllString; note that n<0 means 'all matches'; was n<=0)
|
|
(Plus there are ten new methods you didn't know you wanted.)
|
|
Please update your code to use the new routines before the next release.
|
|
|
|
An image.Image now has a Bounds rectangle, where previously it ranged
|
|
from (0, 0) to (Width, Height). Loops that previously looked like:
|
|
for y := 0; y < img.Height(); y++ {
|
|
for x := 0; x < img.Width(); x++ {
|
|
// Do something with img.At(x, y)
|
|
}
|
|
}
|
|
should instead be:
|
|
b := img.Bounds()
|
|
for y := b.Min.Y; y < b.Max.Y; y++ {
|
|
for x := b.Min.X; x < b.Max.X; x++ {
|
|
// Do something with img.At(x, y)
|
|
}
|
|
}
|
|
The Point and Rectangle types have also moved from exp/draw to image.
|
|
|
|
Other changes:
|
|
* arm: bugfixes and syscall (thanks Kai Backman).
|
|
* asn1: fix incorrect encoding of signed integers (thanks Nicholas Waples).
|
|
* big: fixes to bitwise functions (thanks Evan Shaw).

|
|
* net/textproto: new package, with example net/dict.

This release includes some package changes that may require changes to
|
|
client code.
|
|
|
|
The Split function in the bytes and strings packages has been changed.
|
|
The count argument, which limits the size of the return, previously treated
|
|
zero as unbounded. It now treats 0 as 0, and will return an empty slice.
|
|
To request unbounded results, use -1 (or some other negative value).
|
|
The new Replace functions in bytes and strings share this behavior.
|
|
This may require you change your existing code.
|
|
|
|
The gob package now allows the transmission of non-struct values at the
|
|
top-level. As a result, the rpc and netchan packages have fewer restrictions
|
|
on the types they can handle. For example, netchan can now share a chan int.
|
|
|
|
The release also includes a Code Walk: "Share Memory By Communicating".
|
|
It describes an idiomatic Go program that uses goroutines and channels:
|
|
http://golang.org/doc/codewalk/sharemem/
|
|
|
|
There is now a Projects page on the Go Dashboard that lists Go programs,
|
|
tools, and libraries:
|
|
http://godashboard.appspot.com/project
|
|
|
|
Other changes:
|
|
* 6a, 6l: bug fixes.
|
|
* bytes, strings: add Replace.
|
|
* cgo: use slash-free relative paths for .so references.
|
|

|
|

|
|
* doc/codewalk: add Share Memory By Communicating.
|
|
* exp/draw/x11: implement the mapping from keycodes to keysyms.
|
|
* fmt: Printf: fix bug in handling of %#v, allow other verbs for slices
|
|
Scan: fix handling of EOFs.
|
|
* gc: bug fixes and optimizations.
|
|
* gob: add DecodeValue and EncodeValue,
|
|
add support for complex numbers.
|
|
* goinstall: support for Bazaar+Launchpad (thanks Gustavo Niemeyer).
|
|

|
|
* ld: add -u flag to check safe bits; discard old -u, -x flags.
|
|
* math: amd64 versions of Exp and Fabs (thanks Charles L. Dorian).
|
|
* misc/vim: always override filetype detection for .go files.
|
|
* net: add support for DNS SRV requests (thanks Kirklin McDonald),
|
|
initial attempt to implement Windows version (thanks Alex Brainman).
|
|
* netchan: allow chan of basic types now that gob can handle such,
|
|
eliminate the need for a pointer value in Import and Export.
|
|
* os/signal: only catch all signals if os/signal package imported.
|
|
* regexp: bug fix: need to track whether match begins with fixed prefix.
|
|
* rpc: allow non-struct args and reply (they must still be pointers).
|
|
* runtime: bug fixes and reorganization.
|
|
* strconv: fix bugs in floating-point and base 2 conversions
|
|
* syscall: add syscall_bsd.go to zsycall_freebsd_386.go (thanks Peter Mundy),
|
|

This release includes a language change. The "..." function parameter form is
|
|
gone; "...T" remains. Typically, "...interface{}" can be used instead of "...".
|
|
|
|
The implementation of Printf has changed in a way that subtly affects its
|
|
handling of the fmt.Stringer interface. You may need to make changes to your
|
|
code. For details, see:
|
|
https://groups.google.com/group/golang-nuts/msg/6fffba90a3e3dc06
|
|
|
|
The reflect package has been changed. If you have code that uses reflect,
|
|
it will need to be updated. For details, see:
|
|
https://groups.google.com/group/golang-nuts/msg/7a93d07c590e7beb

This release contains many fixes and improvements, including several
|
|
clarifications and consolidations to the Language Specification.
|
|
|
|
The type checking rules around assignments and conversions are simpler but more
|
|
restrictive: assignments no longer convert implicitly from *[10]int to []int
|
|
(write x[0:] instead of &x), and conversions can no longer change the names of
|
|
types inside composite types.
|
|
|
|

|
|
format-driven (fmt.Scanf) scanners for all basic types.

This release contains three language changes:
|
|
|
|
1. Accessing a non-existent key in a map is no longer a run-time error.
|
|
It now evaluates to the zero value for that type. For example:
|
|
x := myMap[i] is now equivalent to: x, _ := myMap[i]
|
|
|
|
2. It is now legal to take the address of a function's return value.
|
|
The return values are copied back to the caller only after deferred
|
|
functions have run.
|
|
|
|
3. The functions panic and recover, intended for reporting and recovering from
|
|
failure, have been added to the spec:
|
|
http://golang.org/doc/go_spec.html#Handling_panics
|
|
In a related change, panicln is gone, and panic is now a single-argument
|
|
function. Panic and recover are recognized by the gc compilers but the new
|
|
behavior is not yet implemented.
|
|
|
|
The ARM build is broken in this release; ARM users should stay at release.2010-03-22.
|
|
|
|
Other changes:
|
|
* bytes, strings: add IndexAny.
|

There is one language change: the ability to convert a string to []byte or
|
|
[]int. This deprecates the strings.Bytes and strings.Runes functions.
|
|
You can convert your existing sources using these gofmt commands:
|
|
gofmt -r 'strings.Bytes(x) -> []byte(x)' -w file-or-directory-list
|
|
gofmt -r 'strings.Runes(x) -> []int(x)' -w file-or-directory-list
|
|
After running these you might need to delete unused imports of the "strings"
|
|
package.
|
|
|
|
Other changes and fixes:
|
|
* 6l/8l/5l: add -r option
|
|
* 8g: make a[byte(x)] truncate x
|
|
* codereview.py: fix for compatibility with hg >=1.4.3
|
|
* crypto/blowfish: new package (thanks Raif S. Naffah)
|
|
* dashboard: more performance tuning
|
|
* fmt: use String method in %q to get the value to quote.
|
|
* gofmt: several cosmetic changes
|
|
* http: fix handling of Connection: close, bug in http.Post
|
|
* net: correct DNS configuration,
|
|
fix network timeout boundary condition,
|
|
put [ ] around IPv6 addresses for Dial.
|
|
* path: add Match,
|
|
fix bug in Match with non-greedy stars (thanks Kevin Ballard)
|
|
* strings: delete Bytes, Runes (see above)
|
|
* tests: an Eratosthenesque concurrent prime sieve (thanks Anh Hai Trinh)

There are two small language changes: the meaning of chan <- chan int
|
|
is now defined, and functions returning functions do not need to
|
|
parenthesize the result type.
|
|
|
|
There is one significant implementation change: the compilers can
|
|
handle multiple packages using the same name in a single binary.
|
|
In the gc compilers, this comes at the cost of ensuring that you
|
|
always import a particular package using a consistent import path.
|
|
In the gccgo compiler, the cost is that you must use the -fgo-prefix
|
|
flag to pass a unique prefix (like the eventual import path).
|
|
|
|
5a/6a/8a: avoid use of fixed-size buffers (thanks Dean Prichard)

Since the last release there has been one large syntactic change to
|
|
the language, already discussed extensively on this list: semicolons
|
|
are now implied between statement-ending tokens and newline characters.
|
|
See http://groups.google.com/group/golang-nuts/t/5ee32b588d10f2e9 for
|
|
details.
|
|
|
|
By default, gofmt now parses and prints the new lighter weight syntax.
|
|
To convert programs written in the old syntax, you can use:
|
|
|
|
gofmt -oldparser -w *.go
|
|
|
|
Since everything was being reformatted anyway, we took the opportunity to
|
|
change the way gofmt does alignment. Now gofmt uses tabs at the start
|
|
of a line for basic code alignment, but it uses spaces for alignment of
|
|
interior columns. Thus, in an editor with a fixed-width font, you can
|
|
choose your own tab size to change the indentation, and no matter what
|
|
tab size you choose, columns will be aligned properly.
|
|
|
|
|
|
In addition to the syntax and formatting changes, there have been many
|
|
smaller fixes and updates:
|
|
|
|
6g,8g,5g: many bug fixes, better registerization,
|
|
build process fix involving mkbuiltin (thanks Yongjian Xu),

Since the last release there are two changes to the language:
|
|
|

|
|
elements to dst from src and returns n. It works correctly
|
|
even if dst and src overlap. bytes.Copy is gone.

|
Convert your programs using:
|

|
|
|
