<pre>
|
|
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
|
|
* build: $GOBIN defaults to $GOROOT/bin,
|
|
no required environment variables

|
|
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).

|
|
* gofmt: better reporting for unexpected semicolon errors.
|
|
* html: new package, an HTML tokenizer.

|
|

|
|
* libbio: fix Bprint to address 6g issues with large data structures.
|
|
* math: fix amd64 Hypot (thanks Charles L. Dorian).
|
|
* net/textproto: new package, with example net/dict.
|
|
* os: fix ForkExec() handling of envv == nil (thanks Alex Brainman).
|
|
* png: grayscale support (thanks Mathieu Lonjaret).
|

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.
|
|
* cmath: correct IsNaN for argument cmplx(Inf, NaN) (thanks Charles L. Dorian).
|
|
* codereview: allow multiple email addresses in CONTRIBUTORS.
|
|
* 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).
|
|
* io/ioutil: add TempFile for Windows (thanks Peter Mundy).
|
|
* 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),
|
|
add socketpair (thanks Ivan Krasin).

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.
|
|
* 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)
|
|
* 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:
