Please read these notes carefully, as there are many +changes and your code will likely be affected. + +The syntax for map deletion has been changed. Code that looks like: + m[x] = 0, false +should be written as: + delete(m, x) +The compiler still accepts m[x] = 0, false for now; even so, you can use gofix +to rewrite such assignments into delete(m, x). + +The Go compiler will reject a return statement without arguments when any of +the result variables has been shadowed. Code rejected as a result of this +change is likely to be buggy. + +Receive-only channels (<-chan T) cannot be closed. +The compiler will diagnose such attempts. + +The first element of a map iteration is chosen at random. Code that depends on +iteration order will need to be updated. + +Goroutines may be run during program initialization. + +A string may be appended to a byte slice. This code is now legal: + var b []byte + var s string + b = append(b, s...) + +The gotry command and its associated try package have been deleted. +It was a fun experiment that - in the end - didn't carry its weight. + +The gotype tool has been moved to exp/gotype and its associated go/types +package has been moved to exp/types. The deprecated go/typechecker package has +been deleted. + +The enbflint tool has been moved to pkg/exp/ebnflint and its associated ebnf +package has been moved to pkg/exp/ebnf. + +The netchan package has been moved to old/netchan. + +The http/spdy package has been moved to exp/spdy. + +The exp/datafmt package has been deleted. + +The container/vector package has been deleted. Slices are better: + http://code.google.com/p/go-wiki/wiki/SliceTricks + +Other changes: +* 5l/6l/8l: correct ELFRESERVE diagnostic (thanks Anthony Martin). +* 6l/8l: support OS X code signing (thanks Mikkel Krautz). +* asn1: accept UTF8 strings as ASN.1 ANY values. +* big: handle aliasing correctly for Rat.SetFrac. +* build: add missing nuke target (thanks Anthony Martin), + catch future accidental dependencies to exp or old packages, + more robustly detect gold 2.20 (thanks Christopher Wedgwood), + pass $GCFLAGS to compiler, + stop on failed deps.bash. +* crypto/tls: add 3DES ciphersuites, + add server side SNI support, + fetch root CA from Windows store (thanks Mikkel Krautz), + fetch root certificates using Mac OS API (thanks Mikkel Krautz), + fix broken looping code in windows root CA fetcher (thanks Mikkel Krautz), + more Unix root certificate locations. +* crypto/x509: add code for dealing with PKIX public keys, + keep the raw Subject and Issuer. +* csv: fix overly aggressive TrimLeadingSpace. +* exp/ssh: general cleanups for client support (thanks Dave Cheney). +* exp/template/html: fix bug in cssEscaper. +* exp/terminal: split terminal handling from exp/ssh. +* exp/winfsnotify: filesystem watcher for Windows (thanks Hector Chu). +* fmt: fix test relying on map iteration order. +* gc: changes to export format in preparation for inlining, + pass FlagNoPointers to runtime.new, + preserve uint8 and byte distinction in errors and import data, + stricter multiple assignment + test, + treat uintptr as potentially containing a pointer. +* go/scanner: remove AllowIllegalChars mode. +* go/token: document deserialization property. +* gob: avoid one copy for every message written. +* godefs: add enum/const testdata (thanks Dave Cheney). +* godoc: generate package toc in template, not in JavaScript, + show "unexported" declarations when executing "godoc builtin", + show correct source name with -path. +* gofix: make fix order explicit, add mapdelete. +* gofmt: fix //line handling, + disallow rewrites for incomplete programs. +* gotest: avoid conflicts with the name of the tested package (thanks Esko Luontola), + test example code. +* goyacc: clean up after units (thanks Anthony Martin), + make more gofmt-compliant. +* html: add a Render function, various bug fixes and improvements, + parser improvements (thanks Andrew Balholm). +* http: DoS protection: cap non-Handler Request.Body reads, + RoundTrippers shouldn't mutate Request, + avoid panic caused by nil URL (thanks Anthony Martin), + fix read timeouts and closing, + remove Request.RawURL. +* image/tiff: implement PackBits decoding (thanks Benny Siegert). +* ld: fix "cannot create 8.out.exe" (thanks Jaroslavas Počepko). +* misc/emacs: add a "godoc" command, like M-x man (thanks Evan Martin). +* misc/swig: delete binaries (thanks Anthony Martin). +* misc/windows: automated toolchain packager (thanks Joe Poirier). +* net/windows: implement ip protocol name to number resolver (thanks Alex Brainman). +* net: add File method to IPConn (thanks Mikio Hara), + allow LookupSRV on non-standard DNS names, + fix "unexpected socket family" error from WriteToUDP (thanks Albert Strasheim), + fix socket leak in case of Dial failure (thanks Chris Farmiloe), + remove duplicate error information in Dial (thanks Andrey Mirtchovski), + return error from CloseRead and CloseWrite (thanks Albert Strasheim), + skip ICMP test on Windows too unless uid 0. +* reflect: disallow Interface method on Value obtained via unexported name, + make unsafe use of SliceHeader gc-friendly. +* rpc: don't panic on write error. +* runtime: faster strings, + fix crash if user sets MemProfileRate=0, + fix crash when returning from syscall during gc (thanks Hector Chu), + fix memory leak in parallel garbage collector. +* scanner: invalidate scanner.Position when no token is present. +* spec: define order of multiple assignment. +* syscall/windows: dll function load and calling changes (thanks Alex Brainman). +* syscall: add #ifdefs to fix the manual corrections in ztypes_linux_arm.go (thanks Dave Cheney), + adjust Mount to accomodate stricter FS implementations. +* testing: fix time reported for failing tests. +* utf8: add Valid and ValidString. +* websocket: tweak hybi ReadHandshake to support Firefox (thanks Luca Greco). +* xml: match Marshal's XMLName behavior in Unmarshal (thanks Chris Farmiloe). +</pre> + <h2 id="2011-10-06">2011-10-06</h2> <pre> |
