|
||
|
||
<pre>
|
||
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
|
||
}
|
||
|
||

<h3 id="2011-02-01">2011-02-01</h3>
|
||
|
||
<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:
|
||

||

This release removes the float and complex types from the language.
|
||
|
||
The default type for a floating point literal is now float64, and

|

<pre>
|
||
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.
|
||
|
||
Other changes:
|
||
* arm: initial cut at arm optimizer.
|
||
* bytes.Buffer: Fix bug in UnreadByte.
|
||
* cgo: export unsafe.Pointer as void*, fix enum const conflict,

<h3 id="2010-12-15">2010-12-15</h3>
|
||
|
||
<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).
|
||
* [68]l and runtime: GDB support for interfaces and goroutines.
|
||
* 6l, 8l: support for linking ELF and Mach-O .o files.
|
||
* all: simplify two-variable ranges with unused second variable (thanks Ryan Hitchman).
|
||
* arm: updated soft float support.
|
||
* 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.
|
||
* http: ServeFile handles Range header for partial requests.
|
||
* json: check for invalid UTF-8.
|
||
* ld: allow .o files with no symbols,
|
||
reading of ELF object files,
|
||
reading of Mach-O object files.
|
||
* math: change float64 bias constant from 1022 to 1023 (thanks Eoghan Sherry),
|
||
rename the MinFloat constant to SmallestNonzeroFloat.
|
||
* nm: silently ignore .o files in .a files.
|
||
* 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).
|
||
* syscall/windows: restrict access rights param of OpenProcess(),
|
||
remove \r and \n from error messages (thanks Alex Brainman).
|
||
* test/bench: fixes to timing.sh (thanks Anthony Martin).
|
||
* time: fix bug in Ticker: shutdown using channel rather than memory.
|
||
* token/position: provide FileSet.File, provide files iterator.
|
||
* xml: disallow invalid Unicode code points (thanks Nigel Kerr).

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).
|
||
* 8l, runtime: fix Plan 9 386 build (thanks Yuval Pavel Zholkover).
|
||
* all: fix broken calls to Printf etc.
|
||
* bufio: make Reader.Read implement io.Reader semantics (thanks Roger Peppe).
|
||
* build: allow archiver to be specified by HOST_AR (thanks Albert Strasheim).
|
||

|
||
handle multiple calls to flag.Parse.
|
||

|
||
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".
|
||
* go/printer: preserve newlines in func parameter lists (thanks Jamie Gennis).
|
||
* http: consume request body before next request.
|
||
* log: ensure writes are atomic (thanks Roger Peppe).
|
||
* path: Windows support for Split (thanks Benny Siegert).
|
||
* runtime: fix SysFree to really free memory on Windows (thanks Alex Brainman),
|
||
parallel definitions in Go for all C structs.
|
||
* sort: avoid overflow in pivot calculation,
|
||
reduced stack depth to lg(n) in quickSort (thanks Stefan Nilsson).
|
||
* strconv: Atof on Infs and NaNs.

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 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.
|
||
|
||

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

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).
|
||
* os: make tests work on windows (thanks Alex Brainman).
|
||
* runtime: bug fix: serialize mcache allocation,
|
||
correct iteration of large map values,
|
||
faster strequal, memequal (thanks Graham Miller),
|
||

|

<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.
|
||
|
||
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,
|
||
silence warnings generated by ubuntu gcc,
|
||
use full path when compiling libraries.
|
||
* bytes, strings: change lastIndexFunc to use DecodeLastRune (thanks Roger Peppe).
|
||
* 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.
|
||
* http: correct escaping of different parts of URL,
|
||
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).
|
||
* misc/dashboard/builder: remove build files after benchmarking.
|
||
* nacl: update instructions for new SDK.
|
||
* net: enable v4-over-v6 on ip sockets,
|
||
fix crash in DialIP.
|
||
* os: check for valid arguments in windows Readdir (thanks Peter Mundy).
|
||
* runtime: add mmap of null page just in case,
|
||
correct stats in SysFree,
|
||

||

|
||
add inotify on Linux (thanks Balazs Lecz),
|
||
fix socketpair in syscall_bsd,
|
||
fix windows value of IPV6_V6ONLY (thanks Alex Brainman),
|
||
implement windows version of Utimes (thanks Alex Brainman),
|
||
make mkall.sh work for nacl.
|
||
* test: Add test that causes incorrect error from gccgo.

* utf8: add DecodeLastRune and DecodeLastRuneInString (thanks Roger Peppe).

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:
|
||

|
||
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).

|
||

|
||
* 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.

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

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).
|
||

|
||

|
||

|
||
* 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.
|

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
|
||

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

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.

||
preserve newlines in multiline selector expressions (thanks Risto Jaakko Saarelma).

|
||
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
|
||

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),

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)].
