<p>This page summarizes the changes between tagged weekly snapshots of Go.

For full details, see the <a href="http://code.google.com/p/go/source/list">Mercurial change log</a>.</p>
|

|
|
|

|
|
<p>Weekly snapshots occur often and may not be stable.
|
|||
|
|
If stability of API and code is more important than having the
|
|||
|
|
latest features, use the <a href="release.html">official releases</a> instead.</p>
|

|
|

This release includes revisions to the reflect package to make it more
|
|||
|
|
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
|
|||
|
|
http://codereview.appspot.com/4435042
|
|||
|
|
Also, the Typeof and NewValue functions have been renamed to TypeOf and ValueOf.

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The os package's Open function has been replaced by three functions: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.
|
|||
|
|
|
|||
|
|

|
|||
|
|
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.
|
|||
|
|
|
|||
|
|
Other changes:
|
|||
|
|
* 5l, 6l, 8l: reduce binary size about 40% by omitting symbols for type, string, go.string.
|
|||
|
|

This release includes changes to the reflect and path packages.
|
|||
|
|
Code that uses reflect or path may need to be updated.
|

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
|
|||
|
|
}
|
|||
|
|
|
|||
|
|
Other changes:
|
|||
|
|
* 6l: new -Hwindowsgui flag allows to build windows gui pe (thanks Alex Brainman),
|
|||
|
|
pe fixes (thanks Wei Guangjing).
|
|||
|
|
* 8l, 6l: allow for more os threads to be created on Windows (thanks Alex Brainman),
|
|||
|
|
* build: reduce the use of subshells in recursive make, and
|
|||
|
|
remove unused NaCl conditional from make.bash (thanks Dave Cheney).
|
|||
|
|
* codereview: fix clpatch with empty diffs (thanks Gustavo Niemeyer).
|
|||
|
|
* compress/bzip2: add package.
|
|||
|
|
* compress/lzw: implement a decoder.
|
|||
|
|
* crypto/openpgp: add package.

This release includes changes to the io, os, and template packages.
|
|||
|
|
You may need to update your code.
|
|||
|
|
|
|||
|
|
The io.ReadByter and io.ReadRuner interface types have been renamed to
|
|||
|
|
io.ByteReader and io.RuneReader respectively.
|
|||
|
|
|
|||
|
|
The os package's ForkExec function has been superseded by the new StartProcess
|
|||
|
|
function and an API built around the Process type:
|
|||
|
|
http://golang.org/pkg/os/#Process
|
|||
|
|
|
|||
|
|
The order of arguments to template.Execute has been reversed to be consistent
|
|||
|
|
the notion of "destination first", as with io.Copy, fmt.Fprint, and others.
|
|||
|
|
|
|||
|
|
Gotest now works for package main in directories using Make.cmd-based makefiles.
|
|||
|
|
|
|||
|
|
The memory allocation runtime problems from the last release are not completely
|
|||
|
|
fixed. The virtual memory exhaustion problems encountered by people using
|
|||
|
|
ulimit -v have been fixed, but there remain known garbage collector problems
|
|||
|
|
when using GOMAXPROCS > 1.

<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:

|||

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 xml package now allows the extraction of nested XML tags by specifying
|
|||
|
|
struct tags of the form "parent>child". See the XML documentation for an

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 marshalling 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 forseeable 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).

|
|||
|
|
* 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.

|
|||
|
|
reading of ELF object files,
|

|
|
reading of Mach-O object files.

* math: change float64 bias constant from 1022 to 1023 (thanks Eoghan Sherry),
|
|||

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.
|
|||
|
|
|
|||
|

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.
|
|||
|
|
|
|||
|
|

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
|
|||
|
|
(preparation for a different position representation)
|
|||
|
|
* net: provide public access to file descriptors (thanks Keith Rarick)
|
|||
|
|
* 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 includes a language change: the new built-in function, append.
|
|||
|

*** 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.
|
|||
|
|

|
|||
|
|

|||
|
|
* gotest: generate correct gofmt-formatted _testmain.go.
|
|||
|
|
* image/png: speed up paletted encoding ~25% (thanks Brad Fitzpatrick).

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:

|
|||
|
|
* 8l, runtime: initial support for Plan 9 (thanks Yuval Pavel Zholkover).
|
|||
|
|
* 6l, 8l: more improvements on exporting debug information (DWARF).

|
* arm: code gen fixes. Most tests now pass, except for floating point code.
|
|||
|
|
* big: add random number generation (thanks Florian Uekermann).
|
|||
|

* gc: keep track of real actual type of identifiers,
|
|||
|
|
report that shift must be unsigned integer,
|
|||
|
|
select receive with implicit conversion.
|

|
|||
|

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.

|

|
|
|
|||
|
|
<pre>
|
|||
|
|
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.
|
|||
|
|
|
|||
|
|

|
|||

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:

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.
|
|||
|
|
|
|||
|
|

|
|||
|
|

This release includes a package change. In container/vector, the Iter method
|
|||
|
|
has been removed from the Vector, IntVector, and StringVector types. Also, the
|
|||

|
|
Now that Vector is just a slice, any for loops ranging over v.Iter() or

|
|
v.Data() can be changed to range over v instead.

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.
|
|||

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:
|
|||
|
|

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.
|
|||
|
|
|
|||
|
|
The fmt package now includes flexible type-driven (fmt.Scan) and
|
|||
|
|
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.
|
|||
|
|
* cc/ld: Add support for #pragma dynexport,
|
|||
|
|
Rename dynld to dynimport throughout. Cgo users will need to rerun cgo.

|
|||
|
|

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)

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).

|
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),
|
|||
|
|
method expressions for concrete types

Since the last release there are two changes to the language:
|
|||
|
|
|
|||
|
|
* new builtin copy(dst, src) copies n = min(len(dst), len(src))
|
|||
|
|
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:
|
|||
|
|
gofmt -w -r 'bytes.Copy(d, s) -> copy(d, s)' *.go
|
|||
|
|
|
|||
|
|
* new syntax x[lo:] is shorthand for x[lo:len(x)].
|
|||
|
|
Convert your programs using:
|
|||
|
|
gofmt -w -r 'a[b:len(a)] -> a[b:]' *.go
|
|||
|
|
|
|||
|
