This patch adds the gulp command of `validate-commit-messages`
which will validate the range of commits messages present in the
active branch.
This check now runs on CI as part of the linting checks.
Allowed commit message types and scopes are controlled via commit-message.json file
and documented at https://github.com/angular/angular/blob/master/CONTRIBUTING.md#-commit-message-guidelines
This solution is based on old Vojta's code that he wrote for angular/angular.js, that was later adjusted
by @matsko in #13815.
Ideally we should switch over to something like https://www.npmjs.com/package/commitplease
as suggested in #9953 but that package currently doesn't support strict scope checking,
which is one of the primarily goal of this PR.
Note that this PR removes support for "chore" which was previously overused
by everyone on the team.
Closes#13815Fixes#3337
- Introduce `InjectionToken<T>` which is a parameterized and type-safe
version of `OpaqueToken`.
DEPRECATION:
- `OpaqueToken` is now deprecated, use `InjectionToken<T>` instead.
- `Injector.get(token: any, notFoundValue?: any): any` is now deprecated
use the same method which is now overloaded as
`Injector.get<T>(token: Type<T>|InjectionToken<T>, notFoundValue?: T): T;`.
Migration
- Replace `OpaqueToken` with `InjectionToken<?>` and parameterize it.
- Migrate your code to only use `Type<?>` or `InjectionToken<?>` as
injection tokens. Using other tokens will not be supported in the
future.
BREAKING CHANGE:
- Because `injector.get()` is now parameterize it is possible that code
which used to work no longer type checks. Example would be if one
injects `Foo` but configures it as `{provide: Foo, useClass: MockFoo}`.
The injection instance will be that of `MockFoo` but the type will be
`Foo` instead of `any` as in the past. This means that it was possible
to call a method on `MockFoo` in the past which now will fail type
check. See this example:
```
class Foo {}
class MockFoo extends Foo {
setupMock();
}
var PROVIDERS = [
{provide: Foo, useClass: MockFoo}
];
...
function myTest(injector: Injector) {
var foo = injector.get(Foo);
// This line used to work since `foo` used to be `any` before this
// change, it will now be `Foo`, and `Foo` does not have `setUpMock()`.
// The fix is to downcast: `injector.get(Foo) as MockFoo`.
foo.setUpMock();
}
```

CHANGES:
- Remove unused `onDestroy` method on the `KeyValueDiffer` and
`IterableDiffer`.
DEPRECATION:
- `CollectionChangeRecord` is renamed to `IterableChangeRecord`.
`CollectionChangeRecord` is aliased to `IterableChangeRecord` and is
marked as `@deprecated`. It will be removed in `v5.x.x`.
- Deprecate `DefaultIterableDiffer` as it is private class which
was erroneously exposed.
- Deprecate `KeyValueDiffers#factories` as it is private field which
was erroneously exposed.
- Deprecate `IterableDiffers#factories` as it is private field which
was erroneously exposed.
BREAKING CHANGE:
- `IterableChangeRecord` is now an interface and parameterized on `<V>`.
This should not be an issue unless your code does
`new IterableChangeRecord` which it should not have a reason to do.
- `KeyValueChangeRecord` is now an interface and parameterized on `<V>`.
This should not be an issue unless your code does
`new IterableChangeRecord` which it should not have a reason to do.

This was done in order for us to be able to publish tsc-wrapped as @next tag on npm.
The next step is to change the build scripts to version and release @angular/tsc-wrapped
together with all the other packages. I'll create an issue/PR for this.
@angular/language-service now supports using TypeScript 2.1 as the
the TypeScript host. TypeScript 2.1 is now also partially supported
in `ngc` but is not recommended as Tsickle does not yet support 2.1.
Detailed changes:
- remove `UNINITIALIZED`, initialize change detection fields with `undefined`.
* we use `view.numberOfChecks === 0` now everywhere
as indicator whether we are in the first change detection cycle
(previously we used this only in a couple of places).
* we keep the initialization itself as change detection get slower without it.
- remove passing around `throwOnChange` in various generated calls,
and store it on the view as property instead.
- change generated code for bindings to DOM elements as follows:
Before:
```
var currVal_10 = self.context.bgColor;
if (jit_checkBinding15(self.throwOnChange,self._expr_10,currVal_10)) {
self.renderer.setElementStyle(self._el_0,'backgroundColor',((self.viewUtils.sanitizer.sanitize(jit_21,currVal_10) == null)? null: self.viewUtils.sanitizer.sanitize(jit_21,currVal_10).toString()));
self._expr_10 = currVal_10;
}
var currVal_11 = jit_inlineInterpolate16(1,' ',self.context.data.value,' ');
if (jit_checkBinding15(self.throwOnChange,self._expr_11,currVal_11)) {
self.renderer.setText(self._text_1,currVal_11);
self._expr_11 = currVal_11;
}
```,
After:
```
var currVal_10 = self.context.bgColor;
jit_checkRenderStyle14(self,self._el_0,'backgroundColor',null,self._expr_10,self._expr_10=currVal_10,false,jit_21);
var currVal_11 = jit_inlineInterpolate15(1,' ',self.context.data.value,' ');
jit_checkRenderText16(self,self._text_1,self._expr_11,self._expr_11=currVal_11,false);
```

Part of #13651
This change retracts support for metadata version 2.
The collector used to produce version 2 metadata was incomplete
and can cause the AOT compiler to fail to resolve symbols or
produce other spurious errors.
All libraries compiled and published with 2.3.0 ngc will need
to be recompiled and updated with this change.
- New method `UpgradeAdapter.registerForNg1Tests(modules)` declares the
Angular 1 upgrade module and provides it to the `angular.mock.module()`
helper.
This prevents the need to bootstrap the entire hybrid for every test.
Closes#5462, #12675
- Full support for content projection in downgraded Angular 2
components. In particular, this enables multi-slot projection and
other features on <ng-content>.
- Correctly wire up hierarchical injectors for downgraded Angular 2
components: downgraded components inherit the injector of the first
other downgraded Angular 2 component they find up the DOM tree.

feat(tsc-wrapped): recored when to quote a object literal key
Collecting quoted literals is off by default as it introduces
a breaking change in the .metadata.json file. A follow-up commit
will address this.
Fixes#13249Closes#13356
NgIf syntax has been extended to support else clause to display template
when the condition is false. In addition the condition value can now
be stored in local variable, for later reuse. This is especially useful
when used with the `async` pipe.
Example:
```
<div *ngIf="userObservable | async; else loading; let user">
Hello {{user.last}}, {{user.first}}!
</div>
<template #loading>Waiting...</template>
```

## Inheritance Semantics:
Decorators:
1) list the decorators of the class and its parents in the ancestor first order
2) only use the last decorator of each kind (e.g. @Component / ...)
Constructor parameters:
If a class inherits from a parent class and does not declare
a constructor, it inherits the parent class constructor,
and with it the parameter metadata of that parent class.
Lifecycle hooks:
Follow the normal class inheritance model,
i.e. lifecycle hooks of parent classes will be called
even if the method is not overwritten in the child class.
## Example
E.g. the following is a valid use of inheritance and it will
also inherit all metadata:
```
@Directive({selector: 'someDir'})
class ParentDirective {
constructor(someDep: SomeDep) {}
ngOnInit() {}
}
class ChildDirective extends ParentDirective {}
```
Closes#11606Closes#12892
This is needed to resolve symbols without `.d.ts` files.
This bumps the version of the metadata from 1 to 2.
This adds logic into `ng_host.ts` to automatically upgrade
version 1 to version 2 metadata by adding the exported symbols
from the `.d.ts` file.
Add support for the `$postDigest()` and `$onDestroy()` lifecycle hooks.
Better align the behavior of the `$onChanges()` and `$onInit()` lifecycle hooks
with Angular 1.x:
- Call `$onInit()` before pre-linking.
- Always instantiate the controller before calling `$onChanges()`.
Add upgrade-static.umd.js bundles
This allows depending on it without getting a transitive dependency on compiler.
BREAKING CHANGE:
Four newly added APIs in 2.2.0-beta:
downgradeComponent, downgradeInjectable, UpgradeComponent, and UpgradeModule
are no longer exported by @angular/upgrade.
Import these from @angular/upgrade/static instead.
This commit introduces a new API to the ngUpgrade module, which is compatible
with AoT compilation. Primarily, it removes the dependency on reflection
over the Angular 2 metadata by introducing an API where this information
is explicitly defined, in the source code, in a way that is not lost through
AoT compilation.
This commit is a collaboration between @mhevery (who provided the original
design of the API); @gkalpak & @petebacondarwin (who implemented the
API and migrated the specs from the original ngUpgrade tests) and @alexeagle
(who provided input and review).
This commit is an starting point, there is still work to be done:
* add more documentation
* validate the API via internal projects
* align the ngUpgrade compilation of A1 directives closer to the real A1
compiler
* add more unit tests
* consider support for async `templateUrl` A1 upgraded components
Closes#12239
* feat(forms): ngSubmit event exposes $event from original submit event as local variable
Modify NgForm directive and FormGroup directive to expose the original submit event as $event in the ngSubmit event. Modify docs to reflect changes.
This resolves#10920.
* refactor: code cleanup
