<pre>
|
|
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.

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

|
|
* http: add HandleFunc as shortcut to Handle(path, HandlerFunc(func))
|

|
|

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,

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)].

gofmt -w -r 'a[b:len(a)] -> a[b:]' *.go
