On Windows, some Windows 10 builds support only ANSI output, but not input, so these need to be separated. I'm also improving the detection on Mac and Linux to avoid hardcoding the result. Instead, supportsAnsiEscapes will be true if isatty() and the TERM environment variable contains the string 'xterm'. related #28614 R=lrn@google.com Review-Url: https://codereview.chromium.org/2753233002 .

## 1.23.0
|
||
|
||
### Language
|
||
* Allow using URI strings in `part of` declarations to refer to the
|
||
importing library.
|
||
|
||
### Core library changes
|
||
* `dart:core`: Added `Uri.isScheme` function to check the scheme of a URI.
|
||
Example: `uri.isScheme("http")`. Ignores case when comparing.
|
||
* `dart:core`: Make `UriData.parse` validate its input better.
|
||
If the data is base-64 encoded, the data is normalized wrt.
|
||
alphabet and padding, and it contains invalid base-64 data,
|
||
parsing fails. Also normalizes non-base-64 data.
|
||
* `dart:io`: Added functions `File.lastAccessed`, `File.lastAccessedSync`,
|
||
`File.setLastModified`, `File.setLastModifiedSync`, `File.setLastAccessed`,
|
||
and `File.setLastAccessedSync`.
|
||
* `dart:io`: Added `{Stdin,Stdout}.supportsAnsiEscapes`.
|
||
|
||
### Dart VM
|
||
* Calls to `print()` and `Stdout.write*()` now correctly print unicode
|
||
characters to the console on Windows. Calls to `Stdout.add*()` behave as
|
||
before.
|
||
|
||
### Tool changes
|
||
|
||
* Analysis
|
||
|
||
* The `dartanalyzer` now follows the same rules as the analysis server to find an analysis options file,
|
||
stopping when an analysis options file is found:
|
||
* Search up the directory hierarchy looking for an analysis options file.
|
||
* If analyzing a project referencing the [Flutter](https://flutter.io/) package, then use the
|
||
[default Flutter analysis options](https://github.com/flutter/flutter/blob/master/packages/flutter/lib/analysis_options_user.yaml)
|
||
found in `package:flutter`.
|
||
* If in a Bazel workspace, then use the analysis options in `package:dart.analysis_options/default.yaml` if it exists.
|
||
* Use the default analysis options rules.
|
||
* In addition, specific to `dartanalyzer`:
|
||
* an analysis options file can be specified on the command line via `--options`
|
||
and that file will be used instead of searching for an analysis options file.
|
||
* any analysis option specified on the command line (e.g. `--strong` or `--no-strong`)
|
||
takes precedence over any corresponding value specified in the analysis options file.
|
||
|
||
* Dartium, dart2js, and DDC
|
||
|
||
* Imports to `dart:io` are allowed, but the imported library is not supported
|
||
and will likely fail on most APIs at runtime. This change was made as a
|
||
stopgap measure to make it easier to write libraries that share code between
|
||
platforms (like package `http`). This might change again when configuration
|
||
specific imports are supported.
|
||
|
||
## 1.22.0
|
||
|
||
### Language
|
||
|
||
* Breaking change: ['Generalized tear-offs'](https://github.com/gbracha/generalizedTearOffs/blob/master/proposal.md)
|
||
are no longer supported, and will cause errors. We updated the language spec
|
||
and added warnings in 1.21, and are now taking the last step to fully
|
||
de-support them. They were previously only supported in the VM, and there
|
||
are almost no known uses of them in the wild.
|
||
|
||
* The `assert()` statement has been expanded to support an optional second
|
||
`message` argument (SDK issue [27342](https://github.com/dart-lang/sdk/issues/27342)).
|
||
|
||
The message is displayed if the assert fails. It can be any object, and it
|
||
is accessible as `AssertionError.message`. It can be used to provide more
|
||
user friendly exception outputs. As an example, the following assert:
|
||
|
||
```dart
|
||
assert(configFile != null, "Tool config missing. Please see https://goo.gl/k8iAi for details.");
|
||
```
|
||
|
||
would produce the following exception output:
|
||
|
||
```
|
||
Unhandled exception:
|
||
'file:///Users/mit/tmp/tool/bin/main.dart': Failed assertion: line 9 pos 10:
|
||
'configFile != null': Tool config missing. Please see https://goo.gl/k8iAi for details.
|
||
#0 _AssertionError._doThrowNew (dart:core-patch/errors_patch.dart:33)
|
||
#1 _AssertionError._throwNew (dart:core-patch/errors_patch.dart:29)
|
||
#2 main (file:///Users/mit/tmp/tool/bin/main.dart:9:10)
|
||
```
|
||
|
||
* The `Null` type has been moved to the bottom of the type hierarchy. As such,
|
||
it is considered a subtype of every other type. The `null` *literal* was
|
||
always treated as a bottom type. Now the named class `Null` is too:
|
||
|
||
```dart
|
||
const empty = <Null>[];
|
||
|
||
String concatenate(List<String> parts) => parts.join();
|
||
int sum(List<int> numbers) => numbers.fold(0, (sum, n) => sum + n);
|
||
|
||
concatenate(empty); // OK.
|
||
sum(empty); // OK.
|
||
```
|
||
|
||
* Introduce `covariant` modifier on parameters. It indicates that the
|
||
parameter (and the corresponding parameter in any method that overrides it)
|
||
has looser override rules. In strong mode, these require a runtime type
|
||
check to maintain soundness, but enable an architectural pattern that is
|
||
useful in some code.
|
||
|
||
It lets you specialize a family of classes together, like so:
|
||
|
||
```dart
|
||
abstract class Predator {
|
||
void chaseAndEat(covariant Prey p);
|
||
}
|
||
|
||
abstract class Prey {}
|
||
|
||
class Mouse extends Prey {}
|
||
|
||
class Seal extends Prey {}
|
||
|
||
class Cat extends Predator {
|
||
void chaseAndEat(Mouse m) => ...
|
||
}
|
||
|
||
class Orca extends Predator {
|
||
void chaseAndEat(Seal s) => ...
|
||
}
|
||
```
|
||
|
||
This isn't statically safe, because you could do:
|
||
|
||
```dart
|
||
Predator predator = new Cat(); // Upcast.
|
||
predator.chaseAndEat(new Seal()); // Cats can't eat seals!
|
||
```
|
||
|
||
To preserve soundness in strong mode, in the body of a method that uses a
|
||
covariant override (here, `Cat.chaseAndEat()`), the compiler automatically
|
||
inserts a check that the parameter is of the expected type. So the compiler
|
||
gives you something like:
|
||
|
||
```dart
|
||
class Cat extends Predator {
|
||
void chaseAndEat(o) {
|
||
var m = o as Mouse;
|
||
...
|
||
}
|
||
}
|
||
```
|
||
|
||
Spec mode allows this unsound behavior on all parameters, even though users
|
||
rarely rely on it. Strong mode disallowed it initially. Now, strong mode
|
||
lets you opt into this behavior in the places where you do want it by using
|
||
this modifier. Outside of strong mode, the modifier is ignored.
|
||
|
||
* Change instantiate-to-bounds rules for generic type parameters when running
|
||
in strong mode. If you leave off the type parameters from a generic type, we
|
||
need to decide what to fill them in with. Dart 1.0 says just use `dynamic`,
|
||
but that isn't sound:
|
||
|
||
```dart
|
||
class Abser<T extends num> {
|
||
void absThis(T n) { n.abs(); }
|
||
}
|
||
|
||
var a = new Abser(); // Abser<dynamic>.
|
||
a.absThis("not a num");
|
||
```
|
||
|
||
We want the body of `absThis()` to be able to safely assume `n` is at
|
||
least a `num` -- that's why there's a constraint on T, after all. Implicitly
|
||
using `dynamic` as the type parameter in this example breaks that.
|
||
|
||
Instead, strong mode uses the bound. In the above example, it fills it in
|
||
with `num`, and then the second line where a string is passed becomes a
|
||
static error.
|
||
|
||
However, there are some cases where it is hard to figure out what that
|
||
default bound should be:
|
||
|
||
```dart
|
||
class RuhRoh<T extends Comparable<T>> {}
|
||
```
|
||
|
||
Strong mode's initial behavior sometimes produced surprising, unintended
|
||
results. For 1.22, we take a simpler approach and then report an error if
|
||
a good default type argument can't be found.
|
||
|
||
### Core libraries
|
||
|
||
* Define `FutureOr<T>` for code that works with either a future or an
|
||
immediate value of some type. For example, say you do a lot of text
|
||
manipulation, and you want a handy function to chain a bunch of them:
|
||
|
||
```dart
|
||
typedef String StringSwizzler(String input);
|
||
|
||
String swizzle(String input, List<StringSwizzler> swizzlers) {
|
||
var result = input;
|
||
for (var swizzler in swizzlers) {
|
||
result = swizzler(result);
|
||
}
|
||
|
||
return result;
|
||
}
|
||
```
|
||
|
||
This works fine:
|
||
|
||
```dart
|
||
main() {
|
||
var result = swizzle("input", [
|
||
(s) => s.toUpperCase(),
|
||
(s) => () => s * 2)
|
||
]);
|
||
print(result); // "INPUTINPUT".
|
||
}
|
||
```
|
||
|
||
Later, you realize you'd also like to support swizzlers that are
|
||
asynchronous (maybe they look up synonyms for words online). You could make
|
||
your API strictly asynchronous, but then users of simple synchronous
|
||
swizzlers have to manually wrap the return value in a `Future.value()`.
|
||
Ideally, your `swizzle()` function would be "polymorphic over asynchrony".
|
||
It would allow both synchronous and asynchronous swizzlers. Because `await`
|
||
accepts immediate values, it is easy to implement this dynamically:
|
||
|
||
```dart
|
||
Future<String> swizzle(String input, List<StringSwizzler> swizzlers) async {
|
||
var result = input;
|
||
for (var swizzler in swizzlers) {
|
||
result = await swizzler(result);
|
||
}
|
||
|
||
return result;
|
||
}
|
||
|
||
main() async {
|
||
var result = swizzle("input", [
|
||
(s) => s.toUpperCase(),
|
||
(s) => new Future.delayed(new Duration(milliseconds: 40), () => s * 2)
|
||
]);
|
||
print(await result);
|
||
}
|
||
```
|
||
|
||
What should the declared return type on StringSwizzler be? In the past, you
|
||
had to use `dynamic` or `Object`, but that doesn't tell the user much. Now,
|
||
you can do:
|
||
|
||
```dart
|
||
typedef FutureOr<String> StringSwizzler(String input);
|
||
```
|
||
|
||
Like the name implies, `FutureOr<String>` is a union type. It can be a
|
||
`String` or a `Future<String>`, but not anything else. In this case, that's
|
||
not super useful beyond just stating a more precise type for readers of the
|
||
code. It does give you a little better error checking in code that uses the
|
||
result of that.
|
||
|
||
`FutureOr<T>` becomes really important in *generic* methods like
|
||
`Future.then()`. In those cases, having the type system understand this
|
||
magical union type helps type inference figure out the type argument of
|
||
`then()` based on the closure you pass it.
|
||
|
||
Previously, strong mode had hard-coded rules for handling `Future.then()`
|
||
specifically. `FutureOr<T>` exposes that functionality so third-party APIs
|
||
can take advantage of it too.
|
||
|
||
### Tool changes
|
||
|
||
* Dart2Js
|
||
|
||
* Remove support for (long-time deprecated) mixin typedefs.
|
||
|
||
* Pub
|
||
|
||
* Avoid using a barback asset server for executables unless they actually use
|
||
transformers. This makes precompilation substantially faster, produces
|
||
better error messages when precompilation fails, and allows
|
||
globally-activated executables to consistently use the
|
||
`Isolate.resolvePackageUri()` API.
|
||
|
||
* On Linux systems, always ignore packages' original file owners and
|
||
permissions when extracting those packages. This was already the default
|
||
under most circumstances.
|
||
|
||
* Properly close the standard input stream of child processes started using
|
||
`pub run`.
|
||
|
||
* Handle parse errors from the package cache more gracefully. A package whose
|
||
pubspec can't be parsed will now be ignored by `pub get --offline` and
|
||
deleted by `pub cache repair`.
|
||
|
||
* Make `pub run` run executables in spawned isolates. This lets them handle
|
||
signals and use standard IO reliably.
|
||
|
||
* Fix source-maps produced by dart2js when running in `pub serve`: URL
|
||
references to assets from packages match the location where `pub serve`
|
||
serves them (`packages/package_name/` instead of
|
||
`../packages/package_name/`).
|
||
|
||
### Infrastructure changes
|
||
|
||
* The SDK now uses GN rather than gyp to generate its build files, which will
|
||
now be exclusively ninja flavored. Documentation can be found on our
|
||
[wiki](https://github.com/dart-lang/sdk/wiki/Building-with-GN). Also see the
|
||
help message of `tools/gn.py`. This change is in response to the deprecation
|
||
of gyp. Build file generation with gyp will continue to be available in this
|
||
release by setting the environment variable `DART_USE_GYP` before running
|
||
`gclient sync` or `gclient runhooks`, but this will be removed in a future
|
||
release.
|
||
|
||
## 1.21.0 - 2016-12-07
|
||
|
||
### Language
|
||
|
||
* Support generic method syntax. Type arguments are not available at
|
||
runtime. For details, check the
|
||
[informal specification](https://gist.github.com/eernstg/4353d7b4f669745bed3a5423e04a453c).
|
||
* Support access to initializing formals, e.g., the use of `x` to initialize
|
||
`y` in `class C { var x, y; C(this.x): y = x; }`.
|
||
Please check the
|
||
[informal specification](https://gist.github.com/eernstg/cff159be9e34d5ea295d8c24b1a3e594)
|
||
for details.
|
||
* Don't warn about switch case fallthrough if the case ends in a `rethrow`
|
||
statement. (SDK issue
|
||
[27650](https://github.com/dart-lang/sdk/issues/27650))
|
||
* Also don't warn if the entire switch case is wrapped in braces - as long as
|
||
the block ends with a `break`, `continue`, `rethrow`, `return` or `throw`.
|
||
* Allow `=` as well as `:` as separator for named parameter default values.
|
||
|
||
```dart
|
||
enableFlags({bool hidden: false}) { … }
|
||
```
|
||
|
||
can now be replaced by
|
||
|
||
```dart
|
||
enableFlags({bool hidden = false}) { … }
|
||
```
|
||
|
||
(SDK issue [27559](https://github.com/dart-lang/sdk/issues/27559))
|
||
|
||
### Core library changes
|
||
|
||
* `dart:core`: `Set.difference` now takes a `Set<Object>` as argument. (SDK
|
||
issue [27573](https://github.com/dart-lang/sdk/issues/27573))
|
||
|
||
* `dart:developer`
|
||
|
||
* Added `Service` class.
|
||
* Allows inspecting and controlling the VM service protocol HTTP server.
|
||
* Provides an API to access the ID of an `Isolate`.
|
||
|
||
### Tool changes
|
||
|
||
* Dart Dev Compiler
|
||
|
||
* Support calls to `loadLibrary()` on deferred libraries. Deferred libraries
|
||
are still loaded eagerly. (SDK issue
|
||
[27343](https://github.com/dart-lang/sdk/issues/27343))
|
||
|
||
## 1.20.1 - 2016-10-13
|
||
|
||
Patch release, resolves one issue:
|
||
|
||
* Dartium: Fixes a bug that caused crashes. No issue filed.
|
||
|
||
### Strong Mode
|
||
|
||
* It is no longer a warning when casting from dynamic to a composite type
|
||
(SDK issue [27766](https://github.com/dart-lang/sdk/issues/27766)).
|
||
|
||
```dart
|
||
main() {
|
||
dynamic obj = <int>[1, 2, 3];
|
||
// This is now allowed without a warning.
|
||
List<int> list = obj;
|
||
}
|
||
```
|
||
|
||
## 1.20.0 - 2016-10-11
|
||
|
||
### Dart VM
|
||
|
||
* We have improved the way that the VM locates the native code library for a
|
||
native extension (e.g. `dart-ext:` import). We have updated this
|
||
[article on native extensions](https://www.dartlang.org/articles/dart-vm/native-extensions)
|
||
to reflect the VM's improved behavior.
|
||
|
||
* Linux builds of the VM will now use the `tcmalloc` library for memory
|
||
allocation. This has the advantages of better debugging and profiling support
|
||
and faster small allocations, with the cost of slightly larger initial memory
|
||
footprint, and slightly slower large allocations.
|
||
|
||
* We have improved the way the VM searches for trusted root certificates for
|
||
secure socket connections on Linux. First, the VM will look for trusted root
|
||
certificates in standard locations on the file system
|
||
(`/etc/pki/tls/certs/ca-bundle.crt` followed by `/etc/ssl/certs`), and only if
|
||
these do not exist will it fall back on the builtin trusted root certificates.
|
||
This behavior can be overridden on Linux with the new flags
|
||
`--root-certs-file` and `--root-certs-cache`. The former is the path to a file
|
||
containing the trusted root certificates, and the latter is the path to a
|
||
directory containing root certificate files hashed using `c_rehash`.
|
||
|
||
* The VM now throws a catchable `Error` when method compilation fails. This
|
||
allows easier debugging of syntax errors, especially when testing. (SDK issue
|
||
[23684](https://github.com/dart-lang/sdk/issues/23684))
|
||
|
||
### Core library changes
|
||
|
||
* `dart:core`: Remove deprecated `Resource` class.
|
||
Use the class in `package:resource` instead.
|
||
* `dart:async`
|
||
* `Future.wait` now catches synchronous errors and returns them in the
|
||
returned Future. (SDK issue
|
||
[27249](https://github.com/dart-lang/sdk/issues/27249))
|
||
* More aggressively returns a `Future` on `Stream.cancel` operations.
|
||
Discourages to return `null` from `cancel`. (SDK issue
|
||
[26777](https://github.com/dart-lang/sdk/issues/26777))
|
||
* Fixes a few bugs where the cancel future wasn't passed through
|
||
transformations.
|
||
* `dart:io`
|
||
* Added `WebSocket.addUtf8Text` to allow sending a pre-encoded text message
|
||
without a round-trip UTF-8 conversion. (SDK issue
|
||
[27129](https://github.com/dart-lang/sdk/issues/27129))
|
||
|
||
### Strong Mode
|
||
|
||
* Breaking change - it is an error if a generic type parameter cannot be
|
||
inferred (SDK issue [26992](https://github.com/dart-lang/sdk/issues/26992)).
|
||
|
||
```dart
|
||
class Cup<T> {
|
||
Cup(T t);
|
||
}
|
||
main() {
|
||
// Error because:
|
||
// - if we choose Cup<num> it is not assignable to `cOfInt`,
|
||
// - if we choose Cup<int> then `n` is not assignable to int.
|
||
num n;
|
||
C<int> cOfInt = new C(n);
|
||
}
|
||
```
|
||
|
||
* New feature - use `@checked` to override a method and tighten a parameter
|
||
type (SDK issue [25578](https://github.com/dart-lang/sdk/issues/25578)).
|
||
|
||
```dart
|
||
import 'package:meta/meta.dart' show checked;
|
||
class View {
|
||
addChild(View v) {}
|
||
}
|
||
class MyView extends View {
|
||
// this override is legal, it will check at runtime if we actually
|
||
// got a MyView.
|
||
addChild(@checked MyView v) {}
|
||
}
|
||
main() {
|
||
dynamic mv = new MyView();
|
||
mv.addChild(new View()); // runtime error
|
||
}
|
||
```
|
||
|
||
* New feature - use `@virtual` to allow field overrides in strong mode
|
||
(SDK issue [27384](https://github.com/dart-lang/sdk/issues/27384)).
|
||
|
||
```dart
|
||
import 'package:meta/meta.dart' show virtual;
|
||
class Base {
|
||
@virtual int x;
|
||
}
|
||
class Derived extends Base {
|
||
int x;
|
||
|
||
// Expose the hidden storage slot:
|
||
int get superX => super.x;
|
||
set superX(int v) { super.x = v; }
|
||
}
|
||
```
|
||
|
||
* Breaking change - infer list and map literals from the context type as well as
|
||
their values, consistent with generic methods and instance creation
|
||
(SDK issue [27151](https://github.com/dart-lang/sdk/issues/27151)).
|
||
|
||
```dart
|
||
import 'dart:async';
|
||
main() async {
|
||
var b = new Future<B>.value(new B());
|
||
var c = new Future<C>.value(new C());
|
||
var/*infer List<Future<A>>*/ list = [b, c];
|
||
var/*infer List<A>*/ result = await Future.wait(list);
|
||
}
|
||
class A {}
|
||
class B extends A {}
|
||
class C extends A {}
|
||
```
|
||
|
||
### Tool changes
|
||
|
||
* `dartfmt` - upgraded to v0.2.10
|
||
* Don't crash on annotations before parameters with trailing commas.
|
||
* Always split enum declarations if they end in a trailing comma.
|
||
* Add `--set-exit-if-changed` to set the exit code on a change.
|
||
|
||
* Pub
|
||
* Pub no longer generates a `packages/` directory by default. Instead, it
|
||
generates a `.packages` file, called a package spec. To generate
|
||
a `packages/` directory in addition to the package spec, use the
|
||
`--packages-dir` flag with `pub get`, `pub upgrade`, and `pub downgrade`.
|
||

|
||
symlinks](http://news.dartlang.org/2016/10/good-bye-symlinks.html) article
|
||
for details.
|
||
|
||
## 1.19.1 - 2016-09-08
|
||
|
||
Patch release, resolves one issue:
|
||
|
||
* Dartdoc: Fixes a bug that prevented generation of docs.
|
||
(Dartdoc issue [1233](https://github.com/dart-lang/dartdoc/issues/1233))
|
||
|
||
## 1.19.0 - 2016-08-26
|
||
|
||
### Language changes
|
||
|
||
* The language now allows a trailing comma after the last argument of a call and
|
||
the last parameter of a function declaration. This can make long argument or
|
||
parameter lists easier to maintain, as commas can be left as-is when
|
||
reordering lines. For details, see SDK issue
|
||
[26644](https://github.com/dart-lang/sdk/issues/26644).
|
||
|
||
### Tool Changes
|
||
|
||
* `dartfmt` - upgraded to v0.2.9+1
|
||
* Support trailing commas in argument and parameter lists.
|
||
* Gracefully handle read-only files.
|
||
* About a dozen other bug fixes.
|
||
|
||
* Pub
|
||
* Added a `--no-packages-dir` flag to `pub get`, `pub upgrade`, and `pub
|
||
downgrade`. When this flag is passed, pub will not generate a `packages/`
|
||
directory, and will remove that directory and any symlinks to it if they
|
||
exist. Note that this replaces the unsupported `--no-package-symlinks` flag.
|
||
|
||
* Added the ability for packages to declare a constraint on the [Flutter][]
|
||
SDK:
|
||
|
||
```yaml
|
||
environment:
|
||
flutter: ^0.1.2
|
||
sdk: >=1.19.0 <2.0.0
|
||
```
|
||
|
||
A Flutter constraint will only be satisfiable when pub is running in the
|
||
context of the `flutter` executable, and when the Flutter SDK version
|
||
matches the constraint.
|
||
|
||
* Added `sdk` as a new package source that fetches packages from a hard-coded
|
||
SDK. Currently only the `flutter` SDK is supported:
|
||
|
||
```yaml
|
||
dependencies:
|
||
flutter_driver:
|
||
sdk: flutter
|
||
version: ^0.0.1
|
||
```
|
||
|
||
A Flutter `sdk` dependency will only be satisfiable when pub is running in
|
||
the context of the `flutter` executable, and when the Flutter SDK contains a
|
||
package with the given name whose version matches the constraint.
|
||
|
||
* `tar` files on Linux are now created with `0` as the user and group IDs.
|
||
This fixes a crash when publishing packages while using Active Directory.
|
||
|
||
* Fixed a bug where packages from a hosted HTTP URL were considered the same
|
||
as packages from an otherwise-identical HTTPS URL.
|
||
|
||
* Fixed timer formatting for timers that lasted longer than a minute.
|
||
|
||
* Eliminate some false negatives when determining whether global executables
|
||
are on the user's executable path.
|
||
|
||
* `dart2js`
|
||
* `dart2dart` (aka `dart2js --output-type=dart`) has been removed (this was deprecated in Dart 1.11).
|
||
|
||
[Flutter]: https://flutter.io/
|
||
|
||
### Dart VM
|
||
|
||
* The dependency on BoringSSL has been rolled forward. Going forward, builds
|
||
of the Dart VM including secure sockets will require a compiler with C++11
|
||
support. For details, see the
|
||
[Building wiki page](https://github.com/dart-lang/sdk/wiki/Building).
|
||
|
||
### Strong Mode
|
||
|
||
* New feature - an option to disable implicit casts
|
||
(SDK issue [26583](https://github.com/dart-lang/sdk/issues/26583)),
|
||
see the [documentation](https://github.com/dart-lang/dev_compiler/blob/master/doc/STATIC_SAFETY.md#disable-implicit-casts)
|
||
for usage instructions and examples.
|
||
|
||
* New feature - an option to disable implicit dynamic
|
||
(SDK issue [25573](https://github.com/dart-lang/sdk/issues/25573)),
|
||
see the [documentation](https://github.com/dart-lang/dev_compiler/blob/master/doc/STATIC_SAFETY.md#disable-implicit-dynamic)
|
||
for usage instructions and examples.
|
||
|
||
* Breaking change - infer generic type arguments from the
|
||
constructor invocation arguments
|
||
(SDK issue [25220](https://github.com/dart-lang/sdk/issues/25220)).
|
||
|
||
```dart
|
||
var map = new Map<String, String>();
|
||
|
||
// infer: Map<String, String>
|
||
var otherMap = new Map.from(map);
|
||
```
|
||
|
||
* Breaking change - infer local function return type
|
||
(SDK issue [26414](https://github.com/dart-lang/sdk/issues/26414)).
|
||
|
||
```dart
|
||
void main() {
|
||
// infer: return type is int
|
||
f() { return 40; }
|
||
int y = f() + 2; // type checks
|
||
print(y);
|
||
}
|
||
```
|
||
|
||
* Breaking change - allow type promotion from a generic type parameter
|
||
(SDK issue [26414](https://github.com/dart-lang/sdk/issues/26965)).
|
||
|
||
```dart
|
||
void fn/*<T>*/(/*=T*/ object) {
|
||
if (object is String) {
|
||
// Treat `object` as `String` inside this block.
|
||
// But it will require a cast to pass it to something that expects `T`.
|
||
print(object.substring(1));
|
||
}
|
||
}
|
||
```
|
||
|
||
* Breaking change - smarter inference for Future.then
|
||
(SDK issue [25944](https://github.com/dart-lang/sdk/issues/25944)).
|
||
Previous workarounds that use async/await or `.then/*<Future<SomeType>>*/`
|
||
should no longer be necessary.
|
||
|
||
```dart
|
||
// This will now infer correctly.
|
||
Future<List<int>> t2 = f.then((_) => [3]);
|
||
// This infers too.
|
||
Future<int> t2 = f.then((_) => new Future.value(42));
|
||
```
|
||
|
||
* Breaking change - smarter inference for async functions
|
||
(SDK issue [25322](https://github.com/dart-lang/sdk/issues/25322)).
|
||
|
||
```dart
|
||
void test() async {
|
||
List<int> x = await [4]; // was previously inferred
|
||
List<int> y = await new Future.value([4]); // now inferred too
|
||
}
|
||
```
|
||
|
||
* Breaking change - sideways casts are no longer allowed
|
||
(SDK issue [26120](https://github.com/dart-lang/sdk/issues/26120)).
|
||
|
||
## 1.18.1 - 2016-08-02
|
||
|
||
Patch release, resolves two issues and improves performance:
|
||
|
||
* Debugger: Fixes a bug that crashes the VM
|
||
(SDK issue [26941](https://github.com/dart-lang/sdk/issues/26941))
|
||
|
||
* VM: Fixes an optimizer bug involving closures, try, and await
|
||
(SDK issue [26948](https://github.com/dart-lang/sdk/issues/26948))
|
||
|
||
* Dart2js: Speeds up generated code on Firefox
|
||
(https://codereview.chromium.org/2180533002)
|
||
|
||
## 1.18.0 - 2016-07-27
|
||
|
||
### Core library changes
|
||
|
||
* `dart:core`
|
||
* Improved performance when parsing some common URIs.
|
||
* Fixed bug in `Uri.resolve` (SDK issue [26804](https://github.com/dart-lang/sdk/issues/26804)).
|
||
* `dart:io`
|
||
* Adds file locking modes `FileLock.BLOCKING_SHARED` and
|
||
`FileLock.BLOCKING_EXCLUSIVE`.
|
||
|
||
## 1.17.1 - 2016-06-10
|
||
|
||
Patch release, resolves two issues:
|
||
|
||
* VM: Fixes a bug that caused crashes in async functions.
|
||
(SDK issue [26668](https://github.com/dart-lang/sdk/issues/26668))
|
||
|
||
* VM: Fixes a bug that caused garbage collection of reachable weak properties.
|
||
(https://codereview.chromium.org/2041413005)
|
||
|
||
## 1.17.0 - 2016-06-08
|
||
|
||
### Core library changes
|
||
* `dart:convert`
|
||
* Deprecate `ChunkedConverter` which was erroneously added in 1.16.
|
||
|
||
* `dart:core`
|
||
* `Uri.replace` supports iterables as values for the query parameters.
|
||
* `Uri.parseIPv6Address` returns a `Uint8List`.
|
||
|
||
* `dart:io`
|
||
* Added `NetworkInterface.listSupported`, which is `true` when
|
||
`NetworkInterface.list` is supported, and `false` otherwise. Currently,
|
||
`NetworkInterface.list` is not supported on Android.
|
||
|
||
### Tool Changes
|
||
|
||
* Pub
|
||
* TAR files created while publishing a package on Mac OS and Linux now use a
|
||
more portable format.
|
||
|
||
* Errors caused by invalid arguments now print the full usage information for
|
||
the command.
|
||
|
||
* SDK constraints for dependency overrides are no longer considered when
|
||
determining the total SDK constraint for a lockfile.
|
||
|
||
* A bug has been fixed in which a lockfile was considered up-to-date when it
|
||
actually wasn't.
|
||
|
||
* A bug has been fixed in which `pub get --offline` would crash when a
|
||
prerelease version was selected.
|
||
|
||
* Dartium and content shell
|
||
* Debugging Dart code inside iframes improved, was broken.
|
||
|
||
## 1.16.1 - 2016-05-24
|
||
|
||
Patch release, resolves one issue:
|
||
|
||
* VM: Fixes a bug that caused intermittent hangs on Windows.
|
||
(SDK issue [26400](https://github.com/dart-lang/sdk/issues/26400))
|
||
|
||
## 1.16.0 - 2016-04-26
|
||
|
||
### Core library changes
|
||
|
||
* `dart:convert`
|
||
* Added `BASE64URL` codec and corresponding `Base64Codec.urlSafe` constructor.
|
||
|
||
* Introduce `ChunkedConverter` and deprecate chunked methods on `Converter`.
|
||
|
||
* `dart:html`
|
||
|
||
There have been a number of **BREAKING** changes to align APIs with recent
|
||
changes in Chrome. These include:
|
||
|
||
* Chrome's `ShadowRoot` interface no longer has the methods `getElementById`,
|
||
`getElementsByClassName`, and `getElementsByTagName`, e.g.,
|
||
|
||
```dart
|
||
elem.shadowRoot.getElementsByClassName('clazz')
|
||
```
|
||
|
||
should become:
|
||
|
||
```dart
|
||
elem.shadowRoot.querySelectorAll('.clazz')
|
||
```
|
||
|
||
* The `clipboardData` property has been removed from `KeyEvent`
|
||
and `Event`. It has been moved to the new `ClipboardEvent` class, which is
|
||
now used by `copy`, `cut`, and `paste` events.
|
||
|
||
* The `layer` property has been removed from `KeyEvent` and
|
||
`UIEvent`. It has been moved to `MouseEvent`.
|
||
|
||
* The `Point get page` property has been removed from `UIEvent`.
|
||
It still exists on `MouseEvent` and `Touch`.
|
||
|
||
There have also been a number of other additions and removals to `dart:html`,
|
||
`dart:indexed_db`, `dart:svg`, `dart:web_audio`, and `dart:web_gl` that
|
||
correspond to changes to Chrome APIs between v39 and v45. Many of the breaking
|
||
changes represent APIs that would have caused runtime exceptions when compiled
|
||
to Javascript and run on recent Chrome releases.
|
||
|
||
* `dart:io`
|
||
* Added `SecurityContext.alpnSupported`, which is true if a platform
|
||
supports ALPN, and false otherwise.
|
||
|
||
### JavaScript interop
|
||
|
||
For performance reasons, a potentially **BREAKING** change was added for
|
||
libraries that use JS interop.
|
||
Any Dart file that uses `@JS` annotations on declarations (top-level functions,
|
||
classes or class members) to interop with JavaScript code will require that the
|
||
file have the annotation `@JS()` on a library directive.
|
||
|
||
```dart
|
||
@JS()
|
||
library my_library;
|
||
```
|
||
|
||
The analyzer will enforce this by generating the error:
|
||
|
||
The `@JS()` annotation can only be used if it is also declared on the library
|
||
directive.
|
||
|
||
If part file uses the `@JS()` annotation, the library that uses the part should
|
||
have the `@JS()` annotation e.g.,
|
||
|
||
```dart
|
||
// library_1.dart
|
||
@JS()
|
||
library library_1;
|
||
|
||
import 'package:js/js.dart';
|
||
|
||
part 'part_1.dart';
|
||
```
|
||
|
||
```dart
|
||
// part_1.dart
|
||
part of library_1;
|
||
|
||
@JS("frameworkStabilizers")
|
||
external List<FrameworkStabilizer> get frameworkStabilizers;
|
||
```
|
||
|
||
If your library already has a JS module e.g.,
|
||
|
||
```dart
|
||
@JS('array.utils')
|
||
library my_library;
|
||
```
|
||
|
||
Then your library will work without any additional changes.
|
||
|
||
### Analyzer
|
||
|
||
* Static checking of `for in` statements. These will now produce static
|
||
warnings:
|
||
|
||
```dart
|
||
// Not Iterable.
|
||
for (var i in 1234) { ... }
|
||
|
||
// String cannot be assigned to int.
|
||
for (int n in <String>["a", "b"]) { ... }
|
||
```
|
||
|
||
### Tool Changes
|
||
|
||
* Pub
|
||
* `pub serve` now provides caching headers that should improve the performance
|
||
of requesting large files multiple times.
|
||
|
||
* Both `pub get` and `pub upgrade` now have a `--no-precompile` flag that
|
||
disables precompilation of executables and transformed dependencies.
|
||
|
||
* `pub publish` now resolves symlinks when publishing from a Git repository.
|
||
This matches the behavior it always had when publishing a package that
|
||
wasn't in a Git repository.
|
||
|
||
* Dart Dev Compiler
|
||
* The **experimental** `dartdevc` executable has been added to the SDK.
|
||
|
||
* It will help early adopters validate the implementation and provide
|
||
feedback. `dartdevc` **is not** yet ready for production usage.
|
||
|
||
* Read more about the Dart Dev Compiler [here][dartdevc].

|
||
|
||
## 1.15.0 - 2016-03-09
|
||
|
||
### Core library changes
|
||
|
||
* `dart:async`
|
||
* Made `StreamView` class a `const` class.
|
||
|
||
* `dart:core`
|
||
* Added `Uri.queryParametersAll` to handle multiple query parameters with
|
||
the same name.
|
||
|
||
* `dart:io`
|
||
* Added `SecurityContext.usePrivateKeyBytes`,
|
||
`SecurityContext.useCertificateChainBytes`,
|
||
`SecurityContext.setTrustedCertificatesBytes`, and
|
||
`SecurityContext.setClientAuthoritiesBytes`.
|
||
* **Breaking** The named `directory` argument of
|
||
`SecurityContext.setTrustedCertificates` has been removed.
|
||
* Added support to `SecurityContext` for PKCS12 certificate and key
|
||
containers.
|
||
* All calls in `SecurityContext` that accept certificate data now accept an
|
||
optional named parameter `password`, similar to
|
||
`SecurityContext.usePrivateKeyBytes`, for use as the password for PKCS12
|
||
data.
|
||
|
||
### Tool changes
|
||
|
||
* Dartium and content shell
|
||
* The Chrome-based tools that ship as part of the Dart SDK – Dartium and
|
||
content shell – are now based on Chrome version 45 (instead of Chrome 39).
|
||
* Dart browser libraries (`dart:html`, `dart:svg`, etc) *have not* been
|
||
updated.
|
||
* These are still based on Chrome 39.
|
||
* These APIs will be updated in a future release.
|
||
* Note that there are experimental APIs which have changed in the underlying
|
||
browser, and will not work with the older libraries.
|
||
For example, `Element.animate`.
|
||
|
||
* `dartfmt` - upgraded to v0.2.4
|
||
* Better handling for long collections with comments.
|
||
* Always put member metadata annotations on their own line.
|
||
* Indent functions in named argument lists with non-functions.
|
||
* Force the parameter list to split if a split occurs inside a function-typed
|
||
parameter.
|
||
* Don't force a split for before a single named argument if the argument
|
||
itself splits.
|
||
|
||
### Service protocol changes
|
||
|
||
* Fixed a documentation bug where the field `extensionRPCs` in `Isolate`
|
||
was not marked optional.
|
||
|
||
### Experimental language features
|
||
* Added support for [configuration-specific imports](https://github.com/munificent/dep-interface-libraries/blob/master/Proposal.md).
|
||
On the VM and `dart2js`, they can be enabled with `--conditional-directives`.
|
||
|
||
The analyzer requires additional configuration:
|
||
```yaml
|
||
analyzer:
|
||
language:
|
||
enableConditionalDirectives: true
|
||
```
|
||
|
||

* Added a `resolvePackageUri` method to `Isolate`.
|
||
* Added named arguments `packageConfig` and `automaticPackageResolution` to
|
||
the `Isolate.spawnUri` constructor.
|
||
|
||

|
||
|
||
### Tool changes
|
||
|
||
* `dartfmt`
|
||
|
||
* Better line splitting in a variety of cases.
|
||
|
||
* Other optimizations and bug fixes.
|
||
|
||
* Pub
|
||
|
||
* **Breaking:** Pub now eagerly emits an error when a pubspec's "name" field
|
||
is not a valid Dart identifier. Since packages with non-identifier names
|
||
were never allowed to be published, and some of them already caused crashes
|
||
when being written to a `.packages` file, this is unlikely to break many
|
||
people in practice.
|
||
|
||
* **Breaking:** Support for `barback` versions prior to 0.15.0 (released July
|
||
2014) has been dropped. Pub will no longer install these older barback
|
||
versions.
|
||
|
||
* `pub serve` now GZIPs the assets it serves to make load times more similar
|
||
to real-world use-cases.
|
||
|
||
* `pub deps` now supports a `--no-dev` flag, which causes it to emit the
|
||
dependency tree as it would be if no `dev_dependencies` were in use. This
|
||
makes it easier to see your package's dependency footprint as your users
|
||
will experience it.
|
||
|
||
* `pub global run` now detects when a global executable's SDK constraint is no
|
||
longer met and errors out, rather than trying to run the executable anyway.
|
||
|
||
* Pub commands that check whether the lockfile is up-to-date (`pub run`, `pub
|
||
deps`, `pub serve`, and `pub build`) now do additional verification. They
|
||
ensure that any path dependencies' pubspecs haven't been changed, and they
|
||
ensure that the current SDK version is compatible with all dependencies.
|
||
|
||
* Fixed a crashing bug when using `pub global run` on a global script that
|
||
didn't exist.
|
||
|
||
* Fixed a crashing bug when a pubspec contains a dependency without a source
|
||
declared.
|
||
|
||
## 1.13.2 - 2016-01-06
|
||
|
||
Patch release, resolves one issue:
|
||
|
||
* dart2js: Stack traces are not captured correctly (SDK issue [25235]
|
||
(https://github.com/dart-lang/sdk/issues/25235))
|
||
|
||
## 1.13.1 - 2015-12-17
|
||
|
||
Patch release, resolves three issues:
|
||
|
||
* VM type propagation fix: Resolves a potential crash in the Dart VM (SDK commit
|
||
[dff13be]
|
||
(https://github.com/dart-lang/sdk/commit/dff13bef8de104d33b04820136da2d80f3c835d7))
|
||
|
||
* dart2js crash fix: Resolves a crash in pkg/js and dart2js (SDK issue [24974]
|
||
(https://github.com/dart-lang/sdk/issues/24974))
|
||
|
||
* Pub get crash on ARM: Fixes a crash triggered when running 'pub get' on ARM
|
||
processors such as those on a Raspberry Pi (SDK issue [24855]
|
||
(https://github.com/dart-lang/sdk/issues/24855))
|
||
|
||
## 1.13.0 - 2015-11-18
|
||
|
||
### Core library changes
|
||
* `dart:async`
|
||
* `StreamController` added getters for `onListen`, `onPause`, and `onResume`
|
||
with the corresponding new `typedef void ControllerCallback()`.
|
||
* `StreamController` added a getter for `onCancel` with the corresponding
|
||
new `typedef ControllerCancelCallback()`;
|
||
* `StreamTransformer` instances created with `fromHandlers` with no
|
||
`handleError` callback now forward stack traces along with errors to the
|
||
resulting streams.
|
||
|
||
* `dart:convert`
|
||
* Added support for Base-64 encoding and decoding.
|
||
* Added new classes `Base64Codec`, `Base64Encoder`, and `Base64Decoder`.
|
||
* Added new top-level `const Base64Codec BASE64`.
|
||
|
||
* `dart:core`
|
||
* `Uri` added `removeFragment` method.
|
||
* `String.allMatches` (implementing `Pattern.allMatches`) is now lazy,
|
||
as all `allMatches` implementations are intended to be.
|
||
* `Resource` is deprecated, and will be removed in a future release.
|
||
|
||
* `dart:developer`
|
||
* Added `Timeline` class for interacting with Observatory's timeline feature.
|
||
* Added `ServiceExtensionHandler`, `ServiceExtensionResponse`, and `registerExtension` which enable developers to provide their own VM service protocol extensions.
|
||
|
||
* `dart:html`, `dart:indexed_db`, `dart:svg`, `dart:web_audio`, `dart:web_gl`, `dart:web_sql`
|
||
* The return type of some APIs changed from `double` to `num`. Dartium is now
|
||
using
|
||
JS interop for most operations. JS does not distinguish between numeric
|
||
types, and will return a number as an int if it fits in an int. This will
|
||
mostly cause an error if you assign to something typed `double` in
|
||
checked mode. You may
|
||
need to insert a `toDouble()` call or accept `num`. Examples of APIs that
|
||
are affected include `Element.getBoundingClientRect` and
|
||
`TextMetrics.width`.
|
||
|
||
* `dart:io`
|
||
* **Breaking:** Secure networking has changed, replacing the NSS library
|
||
with the BoringSSL library. `SecureSocket`, `SecureServerSocket`,
|
||
`RawSecureSocket`,`RawSecureServerSocket`, `HttpClient`, and `HttpServer`
|
||
now all use a `SecurityContext` object which contains the certificates
|
||
and keys used for secure TLS (SSL) networking.
|
||
|
||
This is a breaking change for server applications and for some client
|
||
applications. Certificates and keys are loaded into the `SecurityContext`
|
||
from PEM files, instead of from an NSS certificate database. Information
|
||
about how to change applications that use secure networking is at
|
||
https://www.dartlang.org/server/tls-ssl.html
|
||
|
||
* `HttpClient` no longer sends URI fragments in the request. This is not
|
||
allowed by the HTTP protocol.
|
||
The `HttpServer` still gracefully receives fragments, but discards them
|
||
before delivering the request.
|
||
* To allow connections to be accepted on the same port across different
|
||
isolates, set the `shared` argument to `true` when creating server socket
|
||
and `HttpServer` instances.
|
||
* The deprecated `ServerSocketReference` and `RawServerSocketReference`
|
||
classes have been removed.
|
||
* The corresponding `reference` properties on `ServerSocket` and
|
||
`RawServerSocket` have been removed.
|
||
|
||
* `dart:isolate`
|
||
* `spawnUri` added an `environment` named argument.
|
||
|
||
### Tool changes
|
||
|
||
* `dart2js` and Dartium now support improved Javascript Interoperability via the
|
||
[js package](https://pub.dartlang.org/packages/js).
|
||
|
||
* `docgen` and `dartdocgen` no longer ship in the SDK. The `docgen` sources have
|
||
been removed from the repository.
|
||
|
||
* This is the last release to ship the VM's "legacy debug protocol".
|
||
We intend to remove the legacy debug protocol in Dart VM 1.14.
|
||
|
||
* The VM's Service Protocol has been updated to version 3.0 to take care
|
||
of a number of issues uncovered by the first few non-observatory
|
||
clients. This is a potentially breaking change for clients.
|
||
|
||
* Dartium has been substantially changed. Rather than using C++ calls into
|
||
Chromium internals for DOM operations it now uses JS interop.
|
||
The DOM objects in `dart:html` and related libraries now wrap
|
||
a JavaScript object and delegate operations to it. This should be
|
||
mostly transparent to users. However, performance and memory characteristics
|
||
may be different from previous versions. There may be some changes in which
|
||
DOM objects are wrapped as Dart objects. For example, if you get a reference
|
||
to a Window object, even through JS interop, you will always see it as a
|
||
Dart Window, even when used cross-frame. We expect the change to using
|
||
JS interop will make it much simpler to update to new Chrome versions.
|
||
|
||
## 1.12.2 - 2015-10-21
|
||
|
||
### Core library changes
|
||
|
||
* `dart:io`
|
||
|
||
* A memory leak in creation of Process objects is fixed.
|
||
|
||
## 1.12.1 - 2015-09-08
|
||
|
||
### Tool changes
|
||
|
||
* Pub
|
||
|
||
* Pub will now respect `.gitignore` when validating a package before it's
|
||
published. For example, if a `LICENSE` file exists but is ignored, that is
|
||
now an error.
|
||
|
||
* If the package is in a subdirectory of a Git repository and the entire
|
||
subdirectory is ignored with `.gitignore`, pub will act as though nothing
|
||
was ignored instead of uploading an empty package.
|
||
|
||
* The heuristics for determining when `pub get` needs to be run before various
|
||
commands have been improved. There should no longer be false positives when
|
||
non-dependency sections of the pubspec have been modified.
|
||
|
||
## 1.12.0 - 2015-08-31
|
||
|
||
### Language changes
|
||
|
||
* Null-aware operators
|
||
* `??`: if null operator. `expr1 ?? expr2` evaluates to `expr1` if
|
||
not `null`, otherwise `expr2`.
|
||
* `??=`: null-aware assignment. `v ??= expr` causes `v` to be assigned
|
||
`expr` only if `v` is `null`.
|
||
* `x?.p`: null-aware access. `x?.p` evaluates to `x.p` if `x` is not
|
||
`null`, otherwise evaluates to `null`.
|
||
* `x?.m()`: null-aware method invocation. `x?.m()` invokes `m` only
|
||
if `x` is not `null`.
|
||
|
||
### Core library changes
|
||
|
||
* `dart:async`
|
||
* `StreamController` added setters for the `onListen`, `onPause`, `onResume`
|
||
and `onCancel` callbacks.
|
||
|
||
* `dart:convert`
|
||
* `LineSplitter` added a `split` static method returning an `Iterable`.
|
||
|
||
* `dart:core`
|
||
* `Uri` class now perform path normalization when a URI is created.
|
||
This removes most `..` and `.` sequences from the URI path.
|
||
Purely relative paths (no scheme or authority) are allowed to retain
|
||
some leading "dot" segments.
|
||
Also added `hasAbsolutePath`, `hasEmptyPath`, and `hasScheme` properties.
|
||
|
||
* `dart:developer`
|
||
* New `log` function to transmit logging events to Observatory.
|
||
|
||
* `dart:html`
|
||
* `NodeTreeSanitizer` added the `const trusted` field. It can be used
|
||
instead of defining a `NullTreeSanitizer` class when calling
|
||
`setInnerHtml` or other methods that create DOM from text. It is
|
||
also more efficient, skipping the creation of a `DocumentFragment`.
|
||
|
||
* `dart:io`
|
||
* Added two new file modes, `WRITE_ONLY` and `WRITE_ONLY_APPEND` for
|
||
opening a file write only.
|
||
[eaeecf2](https://github.com/dart-lang/sdk/commit/eaeecf2ed13ba6c7fbfd653c3c592974a7120960)
|
||
* Change stdout/stderr to binary mode on Windows.
|
||
[4205b29](https://github.com/dart-lang/sdk/commit/4205b2997e01f2cea8e2f44c6f46ed6259ab7277)
|
||
|
||
* `dart:isolate`
|
||
* Added `onError`, `onExit` and `errorsAreFatal` parameters to
|
||
`Isolate.spawnUri`.
|
||
|
||
* `dart:mirrors`
|
||
* `InstanceMirror.delegate` moved up to `ObjectMirror`.
|
||
* Fix InstanceMirror.getField optimization when the selector is an operator.
|
||
* Fix reflective NoSuchMethodErrors to match their non-reflective
|
||
counterparts when due to argument mismatches. (VM only)
|
||
|
||
### Tool changes
|
||
|
||
* Documentation tools
|
||
|
||
* `dartdoc` is now the default tool to generate static HTML for API docs.
|
||
[Learn more](https://pub.dartlang.org/packages/dartdoc).
|
||
|
||
* `docgen` and `dartdocgen` have been deprecated. Currently plan is to remove
|
||
them in 1.13.
|
||
|
||
* Formatter (`dartfmt`)
|
||
|
||
* Over 50 bugs fixed.
|
||
|
||
* Optimized line splitter is much faster and produces better output on
|
||
complex code.
|
||
|
||
* Observatory
|
||
* Allocation profiling.
|
||
|
||
* New feature to display output from logging.
|
||
|
||
* Heap snapshot analysis works for 64-bit VMs.
|
||
|
||
* Improved ability to inspect typed data, regex and compiled code.
|
||
|
||
* Ability to break on all or uncaught exceptions from Observatory's debugger.
|
||
|
||
* Ability to set closure-specific breakpoints.
|
||
|
||
* 'anext' - step past await/yield.
|
||
|
||
* Preserve when a variable has been expanded/unexpanded in the debugger.
|
||
|
||
* Keep focus on debugger input box whenever possible.
|
||
|
||
* Echo stdout/stderr in the Observatory debugger. Standalone-only so far.
|
||
|
||
* Minor fixes to service protocol documentation.
|
||
|
||
* Pub
|
||
|
||
* **Breaking:** various commands that previously ran `pub get` implicitly no
|
||
longer do so. Instead, they merely check to make sure the ".packages" file
|
||
is newer than the pubspec and the lock file, and fail if it's not.
|
||
|
||
* Added support for `--verbosity=error` and `--verbosity=warning`.
|
||
|
||
* `pub serve` now collapses multiple GET requests into a single line of
|
||
output. For full output, use `--verbose`.
|
||
|
||
* `pub deps` has improved formatting for circular dependencies on the
|
||
entrypoint package.
|
||
|
||
* `pub run` and `pub global run`
|
||
|
||
* **Breaking:** to match the behavior of the Dart VM, executables no longer
|
||
run in checked mode by default. A `--checked` flag has been added to run
|
||
them in checked mode manually.
|
||
|
||
* Faster start time for executables that don't import transformed code.
|
||
|
||
* Binstubs for globally-activated executables are now written in the system
|
||
encoding, rather than always in `UTF-8`. To update existing executables,
|
||
run `pub cache repair`.
|
||
|
||
* `pub get` and `pub upgrade`
|
||
|
||
* Pub will now generate a ".packages" file in addition to the "packages"
|
||
directory when running `pub get` or similar operations, per the
|
||
[package spec proposal][]. Pub now has a `--no-package-symlinks` flag that
|
||
will stop "packages" directories from being generated at all.
|
||
|
||
* An issue where HTTP requests were sometimes made even though `--offline`
|
||
was passed has been fixed.
|
||
|
||
* A bug with `--offline` that caused an unhelpful error message has been
|
||
fixed.
|
||
|
||
* Pub will no longer time out when a package takes a long time to download.
|
||
|
||
* `pub publish`
|
||
|
||
* Pub will emit a non-zero exit code when it finds a violation while
|
||
publishing.
|
||
|
||
* `.gitignore` files will be respected even if the package isn't at the top
|
||
level of the Git repository.
|
||
|
||
* Barback integration
|
||
|
||
* A crashing bug involving transformers that only apply to non-public code
|
||
has been fixed.
|
||
|
||
* A deadlock caused by declaring transformer followed by a lazy transformer
|
||
(such as the built-in `$dart2js` transformer) has been fixed.
|
||
|
||
* A stack overflow caused by a transformer being run multiple times on the
|
||
package that defines it has been fixed.
|
||
|
||
* A transformer that tries to read a non-existent asset in another package
|
||
will now be re-run if that asset is later created.
|
||
|
||
[package spec proposal]: https://github.com/lrhn/dep-pkgspec
|
||
|
||
### VM Service Protocol Changes
|
||
|
||
* **BREAKING** The service protocol now sends JSON-RPC 2.0-compatible
|
||
server-to-client events. To reflect this, the service protocol version is
|
||
now 2.0.
|
||
|
||
* The service protocol now includes a `"jsonrpc"` property in its responses, as
|
||
opposed to `"json-rpc"`.
|
||
|
||
* The service protocol now properly handles requests with non-string ids.
|
||
Numeric ids are no longer converted to strings, and null ids now don't produce
|
||
a response.
|
||
|
||
* Some RPCs that didn't include a `"jsonrpc"` property in their responses now
|
||
include one.
|
||
|
||
## 1.11.2 - 2015-08-03
|
||
|
||
### Core library changes
|
||
|
||
* Fix a bug where `WebSocket.close()` would crash if called after
|
||
`WebSocket.cancel()`.
|
||
|
||
## 1.11.1 - 2015-07-02
|
||
|
||
### Tool changes
|
||
|
||
* Pub will always load Dart SDK assets from the SDK whose `pub` executable was
|
||
run, even if a `DART_SDK` environment variable is set.
|
||
|
||
## 1.11.0 - 2015-06-25

|
||
* `Iterable` can now be extended directly. An alternative to extending
|
||
`IterableBase` from `dart:collection`.
|
||
* `List` added an `unmodifiable` constructor.
|
||
[r45334](https://code.google.com/p/dart/source/detail?r=45334)

* `Uri` added a `directory` constructor.
|
||
[d8dbb4a](https://github.com/dart-lang/sdk/commit/d8dbb4a60f5e8a7f874c2a4fbf59eaf1a39f4776)
|
||
* List iterators may not throw `ConcurrentModificationError` as eagerly in
|
||
release mode. In checked mode, the modification check is still as eager
|
||
as possible.
|
||
[r45198](https://github.com/dart-lang/sdk/commit/5a79c03)
|
||
|
||
* `dart:developer` - **NEW**
|
||
* Replaces the deprecated `dart:profiler` library.
|
||
* Adds new functions `debugger` and `inspect`.
|
||
[6e42aec](https://github.com/dart-lang/sdk/blob/6e42aec4f64cf356dde7bad9426e07e0ea5b58d5/sdk/lib/developer/developer.dart)
|
||
|
||
* `dart:io`
|
||
* `FileSystemEntity` added a `uri` property.
|
||
[8cf32dc](https://github.com/dart-lang/sdk/commit/8cf32dc1a1664b516e57f804524e46e55fae88b2)
|
||
* `Platform` added a `static resolvedExecutable` property.
|
||
[c05c8c6](https://github.com/dart-lang/sdk/commit/c05c8c66069db91cc2fd48691dfc406c818d411d)
|
||
|
||
* `dart:html`
|
||
* `Element` methods, `appendHtml` and `insertAdjacentHtml` now take `nodeValidator`
|
||
and `treeSanitizer` parameters, and the inputs are consistently
|
||
sanitized.
|
||
[r45818 announcement](https://groups.google.com/a/dartlang.org/forum/#!topic/announce/GVO7EAcPi6A)
|
||
|
||
* `dart:isolate`
|
||
* **BREAKING** The positional `priority` parameter of `Isolate.ping` and `Isolate.kill` is
|
||
now a named parameter named `priority`.
|
||
* **BREAKING** Removed the `Isolate.AS_EVENT` priority.
|
||
* `Isolate` methods `ping` and `addOnExitListener` now have a named parameter
|
||
`response`.
|
||
[r45092](https://github.com/dart-lang/sdk/commit/1b208bd)
|
||
* `Isolate.spawnUri` added a named argument `checked`.
|
||
* Remove the experimental state of the API.
|
||
|
||
* `dart:profiler` - **DEPRECATED**
|
||
* This library will be removed in 1.12. Use `dart:developer` instead.
|
||
|
||
### Tool changes
|
||
|
||
* This is the first release that does not include the Eclipse-based
|
||
**Dart Editor**.
|
||
See [dartlang.org/tools](https://www.dartlang.org/tools/) for alternatives.
|
||
* This is the last release that ships the (unsupported)
|
||
dart2dart (aka `dart2js --output-type=dart`) utility as part
|
||
of dart2js
|
||
|
||
## 1.10.0 – 2015-04-29
|
||
|
||
### Core library changes
|
||
|
||
* `dart:convert`
|
||
* **POTENTIALLY BREAKING** Fix behavior of `HtmlEscape`. It no longer escapes
|
||
no-break space (U+00A0) anywhere or forward slash (`/`, `U+002F`) in element
|
||
context. Slash is still escaped using `HtmlEscapeMode.UNKNOWN`.

[r45189](https://github.com/dart-lang/sdk/commit/3c39ad2)
|
||
|
||
* `dart:core`
|
||
* `Uri.parse` added `start` and `end` positional arguments.
|
||
|
||
* `dart:html`
|
||
* **POTENTIALLY BREAKING** `CssClassSet` method arguments must now be 'tokens', i.e. non-empty
|
||
strings with no white-space characters. The implementation was incorrect for
|
||
class names containing spaces. The fix is to forbid spaces and provide a
|
||
faster implementation.
|
||
[Announcement](https://groups.google.com/a/dartlang.org/d/msg/announce/jmUI2XJHfC8/UZUCvJH3p2oJ)
|
||
|
||
* `dart:io`
|
||
|
||
* `ProcessResult` now exposes a constructor.
|
||
* `import` and `Isolate.spawnUri` now supports the
|
||
[Data URI scheme](http://en.wikipedia.org/wiki/Data_URI_scheme) on the VM.
|
||
|
||
## Tool Changes
|
||
|
||
### pub
|
||
|
||
* Running `pub run foo` within a package now runs the `foo` executable defined
|
||
by the `foo` package. The previous behavior ran `bin/foo`. This makes it
|
||
easy to run binaries in dependencies, for instance `pub run test`.
|
||
|
||
* On Mac and Linux, signals sent to `pub run` and forwarded to the child
|
||
command.
|
||
|
||

## 1.9.1 – 2015-03-25
|
||
|
||
### Language changes
|
||
|
||
* Support for `async`, `await`, `sync*`, `async*`, `yield`, `yield*`, and `await
|
||
for`. See the [the language tour][async] for more details.
|
||
|
||
* Enum support is fully enabled. See [the language tour][enum] for more details.
|
||
|
||
[async]: https://www.dartlang.org/docs/dart-up-and-running/ch02.html#asynchrony
|
||
[enum]: https://www.dartlang.org/docs/dart-up-and-running/ch02.html#enums
|
||
|
||
### Tool changes
|
||
|
||
* The formatter is much more comprehensive and generates much more readable
|
||
code. See [its tool page][dartfmt] for more details.
|
||
|
||
* The analysis server is integrated into the IntelliJ plugin and the Dart
|
||
editor. This allows analysis to run out-of-process, so that interaction
|
||
remains smooth even for large projects.
|
||
|
||
* Analysis supports more and better hints, including unused variables and unused
|
||
private members.

### Core library changes
|
||
|
||
#### Highlights
|
||
|
||
* There's a new model for shared server sockets with no need for a `Socket`
|
||
reference.
|
||
|
||
* A new, much faster [regular expression engine][regexp].
|
||
|
||
* The Isolate API now works across the VM and `dart2js`.
|
||
|
||
[regexp]: http://news.dartlang.org/2015/02/irregexp-dart-vms-new-regexp.html
|
||
|
||
#### Details
|
||
|
||
For more information on any of these changes, see the corresponding
|
||
documentation on the [Dart API site](http://api.dartlang.org).
|
||
|
||
* `dart:async`:
|
||
|
||
* `Future.wait` added a new named argument, `cleanUp`, which is a callback
|
||
that releases resources allocated by a successful `Future`.
|
||
|
||
* The `SynchronousStreamController` class was added as an explicit name for
|
||
the type returned when the `sync` argument is passed to `new
|
||
StreamController`.
|
||
|
||
* `dart:collection`: The `new SplayTreeSet.from(Iterable)` constructor was
|
||
added.
|
||
|
||
* `dart:convert`: `Utf8Encoder.convert` and `Utf8Decoder.convert` added optional
|
||
`start` and `end` arguments.
|
||
|
||
* `dart:core`:
|
||
|
||
* `RangeError` added new static helper functions: `checkNotNegative`,
|
||
`checkValidIndex`, `checkValidRange`, and `checkValueInInterval`.
|
||
|
||
* `int` added the `modPow` function.
|
||
|
||
* `String` added the `replaceFirstMapped` and `replaceRange` functions.
|
||
|
||
* `dart:io`:
|
||
|
||
* Support for locking files to prevent concurrent modification was added. This
|
||
includes the `File.lock`, `File.lockSync`, `File.unlock`, and
|
||
`File.unlockSync` functions as well as the `FileLock` class.
|
||
|
||
* Support for starting detached processes by passing the named `mode` argument
|
||
(a `ProcessStartMode`) to `Process.start`. A process can be fully attached,
|
||
fully detached, or detached except for its standard IO streams.
|
||
|
||
* `HttpServer.bind` and `HttpServer.bindSecure` added the `v6Only` named
|
||
argument. If this is true, only IPv6 connections will be accepted.
|
||
|
||
* `HttpServer.bind`, `HttpServer.bindSecure`, `ServerSocket.bind`,
|
||
`RawServerSocket.bind`, `SecureServerSocket.bind` and
|
||
`RawSecureServerSocket.bind` added the `shared` named argument. If this is
|
||
true, multiple servers or sockets in the same Dart process may bind to the
|
||
same address, and incoming requests will automatically be distributed
|
||
between them.
|
||
|
||
* **Deprecation:** the experimental `ServerSocketReference` and
|
||
`RawServerSocketReference` classes, as well as getters that returned them,
|
||
are marked as deprecated. The `shared` named argument should be used
|
||
instead. These will be removed in Dart 1.10.
|
||
|
||
* `Socket.connect` and `RawSocket.connect` added the `sourceAddress` named
|
||
argument, which specifies the local address to bind when making a
|
||
connection.
|
||
|
||
* The static `Process.killPid` method was added to kill a process with a given
|
||
PID.
|
||
|
||
* `Stdout` added the `nonBlocking` instance property, which returns a
|
||
non-blocking `IOSink` that writes to standard output.
|
||
|
||
* `dart:isolate`:
|
||
|
||
* The static getter `Isolate.current` was added.
|
||
|
||
* The `Isolate` methods `addOnExitListener`, `removeOnExitListener`,
|
||
`setErrorsFatal`, `addOnErrorListener`, and `removeOnErrorListener` now work
|
||
on the VM.
|
||
|
||
* Isolates spawned via `Isolate.spawn` now allow most objects, including
|
||
top-level and static functions, to be sent between them.
|
||
|
||
## 1.8.5 – 2015-01-21
|
||
|
||
* Code generation for SIMD on ARM and ARM64 is fixed.
|
||
|
||
* A possible crash on MIPS with newer GCC toolchains has been prevented.
|
||
|
||
* A segfault when using `rethrow` was fixed ([issue 21795][]).
|
||
|
||
[issue 21795]: https://code.google.com/p/dart/issues/detail?id=21795
|
||
|
||
## 1.8.3 – 2014-12-10
|
||
|
||
* Breakpoints can be set in the Editor using file suffixes ([issue 21280][]).
|
||
|
||
* IPv6 addresses are properly handled by `HttpClient` in `dart:io`, fixing a
|
||
crash in pub ([issue 21698][]).
|
||
|
||
* Issues with the experimental `async`/`await` syntax have been fixed.
|
||
|
||
* Issues with a set of number operations in the VM have been fixed.
|
||
|
||
* `ListBase` in `dart:collection` always returns an `Iterable` with the correct
|
||
type argument.
|
||
|
||
[issue 21280]: https://code.google.com/p/dart/issues/detail?id=21280
|
||
[issue 21698]: https://code.google.com/p/dart/issues/detail?id=21698
|
||
|
||
## 1.8.0 – 2014-11-28
|
||
|
||
* `dart:collection`: `SplayTree` added the `toSet` function.
|
||
|
||
* `dart:convert`: The `JsonUtf8Encoder` class was added.
|
||
|
||
* `dart:core`:
|
||
|
||
* The `IndexError` class was added for errors caused by an index being outside
|
||
its expected range.
|
||
|
||
* The `new RangeError.index` constructor was added. It forwards to `new
|
||
IndexError`.
|
||
|
||
* `RangeError` added three new properties. `invalidProperty` is the value that
|
||
caused the error, and `start` and `end` are the minimum and maximum values
|
||
that the value is allowed to assume.
|
||
|
||
* `new RangeError.value` and `new RangeError.range` added an optional
|
||
`message` argument.
|
||
|
||
* The `new String.fromCharCodes` constructor added optional `start` and `end`
|
||
arguments.
|
||
|
||
* `dart:io`:
|
||
|
||
* Support was added for the [Application-Layer Protocol Negotiation][alpn]
|
||
extension to the TLS protocol for both the client and server.
|
||
|
||
* `SecureSocket.connect`, `SecureServerSocket.bind`,
|
||
`RawSecureSocket.connect`, `RawSecureSocket.secure`,
|
||
`RawSecureSocket.secureServer`, and `RawSecureServerSocket.bind` added a
|
||
`supportedProtocols` named argument for protocol negotiation.
|
||
|
||
* `RawSecureServerSocket` added a `supportedProtocols` field.
|
||
|
||
* `RawSecureSocket` and `SecureSocket` added a `selectedProtocol` field which
|
||
contains the protocol selected during protocol negotiation.

||
|
||
## 1.7.0 – 2014-10-15
|
||
|
||
### Tool changes
|
||
|
||
* `pub` now generates binstubs for packages that are globally activated so that
|
||
they can be put on the user's `PATH` and used as normal executables. See the
|
||
[`pub global activate` documentation][pub global activate].
|
||
|
||
* When using `dart2js`, deferred loading now works with multiple Dart apps on
|
||
the same page.
|
||
|
||
[pub global activate]: https://www.dartlang.org/tools/pub/cmd/pub-global.html#running-a-script-from-your-path
|
||
|
||
### Core library changes
|
||
|
||
* `dart:async`: `Zone`, `ZoneDelegate`, and `ZoneSpecification` added the
|
||
`errorCallback` function, which allows errors that have been programmatically
|
||
added to a `Future` or `Stream` to be intercepted.
|
||
|
||
* `dart:io`:
|
||
|
||
* **Breaking change:** `HttpClient.close` must be called for all clients or
|
||
they will keep the Dart process alive until they time out. This fixes the
|
||
handling of persistent connections. Previously, the client would shut down
|
||
immediately after a request.
|
||
|
||
* **Breaking change:** `HttpServer` no longer compresses all traffic by
|
||
default. The new `autoCompress` property can be set to `true` to re-enable
|
||
compression.
|
||
|
||
* `dart:isolate`: `Isolate.spawnUri` added the optional `packageRoot` argument,
|
||
which controls how it resolves `package:` URIs.
