As of Angular v4, four of the options for
`ExtraOptions#initialNavigation` have been deprecated. We intend
to remove them in v11. The final state for these options is:
`enabledBlocking`, `enabledNonBlocking`, and `disabled`. We plan
to remove and deprecate the remaining option in the next two
major releases.
New options:
- `enabledNonBlocking`: same as legacy_enabled
- `enabledBlocking`: same as enabled
BREAKING CHANGE:
* The `initialNavigation` property for the options in
`RouterModule.forRoot` no longer supports `legacy_disabled`,
`legacy_enabled`, `true`, or `false` as valid values.
`legacy_enabled` (the old default) is instead `enabledNonBlocking`
* `enabled` is deprecated as a valid value for the
`RouterModule.forRoot` `initialNavigation` option. `enabledBlocking`
has been introduced to replace it

`TNodeType.View` was created to support inline views. That feature did
not materialize and we have since removed the instructions for it, leave
an unneeded `TNodeType.View` which was still used in a very
inconsistent way. This change no longer created `TNodeType.View` (and
there will be a follow up chang to completely remove it.)

`previousOrParentTNode` stores current `TNode`. Due to inconsistent
implementation the value stored would sometimes belong to the current

for it. A better solution is to just ensure that `previousOrParentTNode`
always belongs to current `TNode`. This simplifies the mental model
and cleans up some code.

In general, the router only matches and loads a single Route config tree. However,
named outlets with empty paths are a special case where the router can
and should actually match two different `Route`s and ensure that the
modules are loaded for each match.
This change updates the "ApplyRedirects" stage to ensure that named
outlets with empty paths finish loading their configs before proceeding
to the next stage in the routing pipe. This is necessary because if the
named outlet has `loadChildren` but the associated lazy config is not loaded
before following stages attempt to match and activate relevant `Route`s,
an error will occur.

Currently we read lifecycle hooks eagerly during `ɵɵdefineComponent`.
The result is that it is not possible to do any sort of meta-programing
such as mixins or adding lifecycle hooks using custom decorators since
any such code executes after `ɵɵdefineComponent` has extracted the
lifecycle hooks from the prototype. Additionally the behavior is
inconsistent between AOT and JIT mode. In JIT mode overriding lifecycle
hooks is possible because the whole `ɵɵdefineComponent` is placed in
getter which is executed lazily. This is because JIT mode must compile a
template which can be specified as `templateURL` and those we are
waiting for its resolution.
- `+` `ɵɵdefineComponent` becomes smaller as it no longer needs to copy
lifecycle hooks from prototype to `ComponentDef`
- `-` `ɵɵNgOnChangesFeature` feature is now always included with the
codebase as it is no longer tree shakable.
Previously we have read lifecycle hooks from prototype in the
`ɵɵdefineComponent` so that lifecycle hook access would be monomorphic.
This decision was made before we had `T*` data structures. By not
reading the lifecycle hooks we are moving the megamorhic read form
`ɵɵdefineComponent` to instructions. However, the reads happen on
`firstTemplatePass` only and are subsequently cached in the `T*` data
structures. The result is that the overall performance should be same
(or slightly better as the intermediate `ComponentDef` has been
removed.)
- [ ] Remove `ɵɵNgOnChangesFeature` from compiler. (It will no longer
be a feature.)
- [ ] Discuss the future of `Features` as they hinder meta-programing.

The current method of handling duplicate navigations caused by 'hashchange' and 'popstate' events for the same url change does not correctly handle cancelled navigations. Because `scheduleNavigation` is called in a `setTimeout` in the location change subscription, the duplicate navigations are not flushed at the same time. This means that if the initial navigation hits a guard that schedules a new navigation, the navigation for the duplicate event will not compare to the correct transition (because we inserted another navigation between the duplicates).

In the early Zone.js versions (< 0.10.3), `ZoneAwarePromise` did not support `Symbol.species`,
so when user used a 3rd party `Promise` such as `es6-promise`, and try to load the promise library after import of `zone.js`, the loading promise library will overwrite the patched `Promise` from `zone.js` and will break `Promise` semantics with respect to `zone.js`.
Starting with `zone.js` 0.10.3, `Symbol.species` is supported therefore this will not longer be an issue. (https://github.com//pull/34533)
Before 0.10.3, the logic in zone.js tried to handle the case in the wrong way. It did so by overriding the descriptor of `global.Promise`, to allow the 3rd party libraries to override native `Promise` instead of `ZoneAwarePromise`. This is not the correct solution, and since the `Promise.species` is now supported, the 3rd party solution of overriding `global.Promise` is no longer needed.
PR removes the wrong work around logic. (This will improve the bundle size.)

This PR provides a more helpful error than the one currently present:
`el.setAttribute is not a function`. It is not valid to have directives with host bindings
on `ng-template` or `ng-container` nodes. VE would silently ignore this, while Ivy
attempts to set the attribute and throws an error because these are comment nodes
and do not have `setAttribute` functionality.
It is better to throw a helpful error than to silently ignore this because
putting a directive with host binding on an `ng-template` or `ng-container` is most often a mistake.
Developers should be made aware that the host binding will have no effect in these cases.
Note that an error is already thrown in Ivy, as mentioned above, so this
is not a breaking change and can be merged to both master and patch.

In #37221 we disabled tsickle passes from transforming the tsc output that is used to publish all
Angular framework and components packages (@angular/*).
This change however revealed a bug in the ngc that caused __decorate and __metadata calls to still
be emitted in the JS code even though we don't depend on them.
Additionally it was these calls that caused code in @angular/material packages to fail at runtime
due to circular dependency in the emitted decorator code documeted as
https://github.com/microsoft/TypeScript/issues/27519.
This change partially rolls back #37221 by reenabling the decorator to static fields (static
properties) downleveling.

FW-2199.

As of TypeScript 3.9, the tsc emit is not compatible with Closure
Compiler due to
https://github.com/microsoft/TypeScript/pull/32011.
There is some hope that this will be fixed by a solution like the one
proposed in
https://github.com/microsoft/TypeScript/issues/38374 but currently it's
unclear if / when that will
happen.
Since the Closure support has been somewhat already broken, and the
tsickle pass has been a source
of headaches for some time for Angular packages, we are removing it for
now while we rethink our
strategy to make Angular Closure compatible outside of Google.
This change has no effect on our Closure compatibility within Google
which work well because all the
code is compiled from sources and passed through tsickle.
This change only disables the tsickle pass but doesn't remove it.
A follow up PR should either remove all the traces of tscikle or
re-enable the fixed version.
BREAKING CHANGE: Angular npm packages no longer contain jsdoc comments
to support Closure Compiler's advanced optimizations
The support for Closure compiler in Angular packages has been
experimental and broken for quite some
time.
As of TS3.9 Closure is unusable with the JavaScript emit. Please follow
https://github.com/microsoft/TypeScript/issues/38374 for more
information and updates.
If you used Closure compiler with Angular in the past, you will likely
be better off consuming
Angular packages built from sources directly rather than consuming the
version we publish on npm
which is primarily optimized for Webpack/Rollup + Terser build pipeline.
As a temporary workaround you might consider using your current build
pipeline with Closure flag
`--compilation_level=SIMPLE`. This flag will ensure that your build
pipeline produces buildable and
runnable artifacts, at the cost of increased payload size due to
advanced optimizations being disabled.
If you were affected by this change, please help us understand your
needs by leaving a comment on https://github.com/angular/angular/issues/37234.

Only refresh transplanted views at the insertion location in Ivy.
Previously, Ivy would check transplanted views at both the insertion and
declaration points. This is achieved by adding a marker to the insertion
tree when we encounter a transplanted view that needs to be refreshed at
its declaration. We use this marker as an extra indication that we still
need to descend and refresh those transplanted views at their insertion
locations even if the insertion view and/or its parents are not dirty.
This change fixes several issues:
* Transplanted views refreshed twice if both insertion and declaration
are dirty. This could be an error if the insertion component changes
result in data not being available to the transplanted view because it
is slated to be removed.
* CheckAlways transplanted views not refreshed if shielded by
non-dirty OnPush (fixes#35400)
* Transplanted views still refreshed when insertion tree is detached
