| <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. |

| <h3 id="2010-12-08">2010-12-08</h3> |
| |
| <pre> |
| 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). |
| * bytes: add Buffer.UnreadRune, Buffer.UnreadByte (thanks Roger Peppe). |
| * crypto/tls: fix build of certificate generation example (thanks Christian Himpel). |
| * doc/install: describe GOHOSTOS and GOHOSTARCH. |
| * errchk: accept multiple source files (thanks Eoghan Sherry). |

| <h3 id="2010-12-02">2010-12-02</h3> |
| |
| <pre> |
| 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. |

| <h3 id="2010-11-23">2010-11-23</h3> |
| |
| <pre> |
| This release includes a backwards-incompatible package change to the |
| sort.Search function (introduced in the last release). |
| See the change for details and examples of how you might change your code: |
| http://code.google.com/p/go/source/detail?r=102866c369 |
| |
| * build: automatically #define _64BIT in 6c. |
| * cgo: print required space after parameter name in wrapper function. |
| * crypto/cipher: new package to replace crypto/block (thanks Adam Langley). |
| * crypto/elliptic: new package, implements elliptic curves over prime fields (thanks Adam Langley). |
| * crypto/x509: policy OID support and fixes (thanks Adam Langley). |
| * doc: add link to codewalks, |
| fix recover() documentation (thanks Anschel Schaffer-Cohen), |
| explain how to write Makefiles for commands. |
| * exec: enable more tests on windows (thanks Alex Brainman). |
| * gc: adjustable hash code in typecheck of composite literals |
| (thanks to vskrap, Andrey Mirtchovski, and Eoghan Sherry). |
| * gc: better error message for bad type in channel send (thanks Anthony Martin). |
| * godoc: bug fix in relativePath, |
| compute search index for all file systems under godoc's observation, |
| use correct time stamp to indicate accuracy of search result. |
| * index/suffixarray: use sort.Search. |
| * net: add ReadFrom and WriteTo windows version (thanks Wei Guangjing). |
| * reflect: remove unnecessary casts in Get methods. |
| * rpc: add RegisterName to allow override of default type name. |
| * runtime: free memory allocated by windows CommandLineToArgv (thanks Alex Brainman). |
| * sort: simplify Search (thanks Roger Peppe). |
| * strings: add LastIndexAny (thanks Benny Siegert). |
| </pre> |
| |
| <h3 id="2010-11-10">2010-11-10</h3> |
| |
| <pre> |
| 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. |
| </pre> |
| |
| <h3 id="2010-11-02">2010-11-02</h3> |
| |
| <pre> |
| This release includes a language change: the new built-in function, append. |
| Append makes growing slices much simpler. See the spec for details: |
| http://golang.org/doc/go_spec.html#Appending_and_copying_slices |
| |
| Other changes: |
| * 8l: pe generation fixes (thanks Alex Brainman). |
| * doc: Effective Go: append and a few words about "..." args. |
| * build: fiddle with make variables. |

| *** 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. |
| * goinstall: display helpful message when encountering a cgo package, |
| fix test for multiple package names (thanks Fazlul Shahriar). |
| * 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. |
| * runtime: print unknown types in panic. |
| * spec: append built-in (not yet implemented). |
| * src: gofmt -s -w src misc. |
| update code to use copy-from-string. |
| * test/bench: update numbers. |
| * websocket: fix short Read. |

| <h3 id="2010-10-20">2010-10-20</h3> |
| |
| <pre> |
| 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. |
| * 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. |
| * goplay: fix to run under windows (thanks Yasuhiro Matsumoto). |
| * http: do not close connection after sending HTTP/1.0 request. |
| * netchan: add new method Hangup to terminate transmission on a channel. |
| * os: change TestForkExec so it can run on windows (thanks Yasuhiro Matsumoto). |
| * runtime: don't let select split stack. |
| * syscall/arm: correct 64-bit system call arguments. |

| <pre> |
| 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), |
| fix argument dump in traceback, |
| fix tiny build. |
| * smtp: new package (thanks Evan Shaw). |
| * syscall: add sockaddr_ll support for linux/386, linux/amd64 (thanks Mikio Hara), |
| add ucred structure for SCM_CREDENTIALS over UNIX sockets. (thanks Albert Strasheim). |
| * syscall: implement WaitStatus and Wait4() for windows (thanks Wei Guangjing). |
| * time: add After. |
| * websocket: enable tests on windows (thanks Alex Brainman). |

| <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. |
| |

| * 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. |

| <h3 id="2010-08-25">2010-08-25</h3> |
| |
| <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 |

| * codereview: fix issues with leading tabs in CL descriptions, |
| do not send "Abandoned" mail if the CL has not been mailed. |

| <h3 id="2010-08-11">2010-08-11</h3> |
| |
| <pre> |
| 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). |
| * bytes: add IndexRune, FieldsFunc and To*Special (thanks Christian Himpel). |

| * html: new package, an HTML tokenizer. |
| * image: change image representation from slice-of-slices to linear buffer, |
| introduce Decode and RegisterFormat, |
| introduce Transparent and Opaque, |
| replace Width and Height by Bounds, add the Point and Rect types. |
| * 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). |
| * regexp: document that backslashes are the escape character. |
| * rpc: catch errors from ReadResponseBody. |
| * runtime: memory free fix (thanks Alex Brainman). |
| * template: add ParseFile method to template.Template. |
| * test/peano: use directly recursive type def. |
| </pre> |

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

| <pre> |
| 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). |
| * time: implement time zones for Windows (thanks Alex Brainman). |
| * x509: support non-self-signed certs. |

| This release includes a language change. The "..." function parameter form is |
| gone; "...T" remains. Typically, "...interface{}" can be used instead of "...". |

| 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 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. |
| |

| 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: |

| 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), |
| method expressions for concrete types |

| installation of .so to non-standard locations |

| encoding/binary: support for slices of fixed-size values (thanks Maxim Ushakov) |
| exp/vector: experimental alternate vector representation (thanks Jan Mercl) |

| 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 |
| |
