Sonu Kapoor 1150649139 perf(core): use `ngDevMode` to tree-shake error messages (#38612)
This commit adds `ngDevMode` guard to throw some errors only in dev mode
(similar to how things work in other parts of Ivy runtime code). The
`ngDevMode` flag helps to tree-shake these error messages from production
builds (in dev mode everything will work as it works right now) to decrease
production bundle size.

This commit adds a guard before throwing any forms errors. This will tree-shake
error messages which cannot be minified. It should also help to reduce the
bundle size of the `forms` package in production by ~20%.

Andrew Kushnir 856db56cca refactor(forms): get rid of duplicate functions (#38371)
This commit performs minor refactoring in Forms package to get rid of duplicate functions.
It looks like the functions were duplicated due to a slightly different type signatures, but
their logic is completely identical. The logic in retained functions remains the same and now
these function also accept a generic type to achieve the same level of type safety.

Paul Gschwendtner e382632473 build: fix symbol extractor not dealing with ES2015 classes (#38093)
We recently reworked our `ng_rollup_bundle` rule to no longer output
ESM5 and to optimize applications properly (previously applications were
not optimized properly due to incorrect build optimizer setup).

This change meant that a lot of symbols have been removed from the
golden correctly. See: fd65958b88

Unfortunately though, a few symbols have been accidentally removed
because they are now part of the bundle as ES2015 classes which the
symbol extractor does not pick up. This commit fixes the symbol
extractor to capture ES2015 classes. We also update the golden to
reflect this change.

Misko Hevery 737506e79c fix(core): Allow modification of lifecycle hooks any time before bootstrap (#35464)
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.

Paul Gschwendtner fd65958b88 test: update symbol goldens to reflect optimized application (#37623)
Interestingly enough, our rollup bundle optimization pipeline
did not work properly before 1b827b058e5060963590628d4735e6ac83c6dfdd.

Unused declarations were not elided because build optimizer did not
consider the Angular packages as side-effect free. Build optimizer has
a hard-coded list of Angular packages that are considered side-effect
free. Though this one did not match in the old version of the rollup
bundle rule, as internal sources were resolved through their resolved
bazel-out paths. Hence build optimizer could not detect the known
Angular framework packages. Now though, since we leverage the
Bazel-idiomatic `@bazel/rollup` implementation, sources are resolved
through linked `node_modules`, and build optimizer is able to properly
detect files as side-effect free.

Paul Gschwendtner 401ef71ae5 fix(compiler-cli): downlevel angular decorators to static properties (#37382)
In v7 of Angular we removed `tsickle` from the default `ngc` pipeline.
This had the negative potential of breaking ES2015 output and SSR due
to a limitation in TypeScript.

TypeScript by default preserves type information for decorated constructor
parameters when `emitDecoratorMetadata` is enabled. For example,
consider this snippet below:

```
@Directive()
export class MyDirective {
  constructor(button: MyButton) {}
}

export class MyButton {}
```

TypeScript would generate metadata for the `MyDirective` class it has
a decorator applied. This metadata would be needed in JIT mode, or
for libraries that provide `MyDirective` through NPM. The metadata would
look as followed:

```
let MyDirective = class MyDir {}

MyDirective = __decorate([
  Directive(),
  __metadata("design:paramtypes", [MyButton]),
], MyDirective);

let MyButton = class MyButton {}
```

Notice that TypeScript generated calls to `__decorate` and
`__metadata`. These calls are needed so that the Angular compiler
is able to determine whether `MyDirective` is actually an directive,
and what types are needed for dependency injection.

The limitation surfaces in this concrete example because `MyButton`
is declared after the `__metadata(..)` call, while `__metadata`
actually directly references `MyButton`. This is illegal though because
`MyButton` has not been declared at this point. This is due to the
so-called temporal dead zone in JavaScript. Errors like followed will
be reported at runtime when such file/code evaluates:

```
Uncaught ReferenceError: Cannot access 'MyButton' before initialization
```

As noted, this is a TypeScript limitation because ideally TypeScript
shouldn't evaluate `__metadata`/reference `MyButton` immediately.
Instead, it should defer the reference until `MyButton` is actually
declared. This limitation will not be fixed by the TypeScript team
though because it's a limitation as per current design and they will
only revisit this once the tc39 decorator proposal is finalized
(currently stage-2 at time of writing).

Given this wontfix on the TypeScript side, and our heavy reliance on
this metadata in libraries (and for JIT mode), we intend to fix this
from within the Angular compiler by downleveling decorators to static
properties that don't need to evaluate directly. For example:

```
MyDirective.ctorParameters = () => [MyButton];
```

With this snippet above, `MyButton` is not referenced directly. Only
lazily when the Angular runtime needs it. This mitigates the temporal
dead zone issue caused by a limitation in TypeScript's decorator
metadata output. See: https://github.com/microsoft/TypeScript/issues/27519.

In the past (as noted; before version 7), the Angular compiler by
default used tsickle that already performed this transformation. We
moved the transformation to the CLI for JIT and `ng-packager`, but now
we realize that we can move this all to a single place in the compiler
so that standalone ngc consumers can benefit too, and that we can
disable tsickle in our Bazel `ngc-wrapped` pipeline (that currently
still relies on tsickle to perform this decorator processing).

This transformation also has another positive side-effect of making
Angular application/library code more compatible with server-side
rendering. In principle, TypeScript would also preserve type information
for decorated class members (similar to how it did that for constructor
parameters) at runtime. This becomes an issue when your application
relies on native DOM globals for decorated class member types. e.g.

```
@Input() panelElement: HTMLElement;
```

Your application code would then reference `HTMLElement` directly
whenever the source file is loaded in NodeJS for SSR. `HTMLElement`
does not exist on the server though, so that will become an invalid
reference. One could work around this by providing global mocks for
these DOM symbols, but that doesn't match up with other places where
dependency injection is used for mocking DOM/browser specific symbols.

More context in this issue: #30586. The TL;DR here is that the Angular
compiler does not care about types for these class members, so it won't
ever reference `HTMLElement` at runtime.

Fixes #30106. Fixes #30586. Fixes #30141.

Andrew Scott 1786586747 fix(core): Refresh transplanted views at insertion point only (#35968)
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

Andrew Kushnir 168a393589 refactor(core): misc refactoring to support upcoming changes to improve synthetic host bindings (#35884)
This commit performs a few updates to internal functions that would be required in upcoming changes to support synthetic host bindings in Directives.

* the `elementPropertyInternal` function was refactored to accept renderer as an argument (prior to that, there was a function that loads the renderer in some specific way for animation bindings)
* `elementPropertyInternal`, `elementAttributeInternal` and `listenerInternal` functions were updated to have a fixed set of arguments (for better performance)
* `elementPropertyInternal` and `elementAttributeInternal` functions were updated to take `tNode` as an argument instead of passing node index (that was used to retrieve `tNode` internally), in some cases we already have `tNode` available or we can retrieve it from the state

The refactoring was triggered by the need to pass different renderers to the `elementPropertyInternal` to support synthetic host bindings in Directives (see this comment for additional context: https://github.com/angular/angular/pull/35568/files#r388034584).

Misko Hevery ee8b8f52aa feat(ivy): Change static priority resolution to be same level as directive it belongs to (#34938)
This change changes the priority order of static styling.

Current priority:
```
(least priority)
- Static
  - Component
  - Directives
  - Template
- Dynamic Binding
  - Component
    - Map/Interpolation
    - Property
  - Directives
    - Map/Interpolation
    - Property
  - Template
    - Map/Interpolation
    - Property
(highest priority)
```

The issue with the above priority is this use case:

```
<div style="color: red;" directive-which-sets-color-blue>
```
In the above case the directive will win and the resulting color will be `blue`. However a small change of adding interpolation to the example like so. (Style interpolation is coming in https://github.com/angular/angular/pull/34202)
```
<div style="color: red; width: {{exp}}px" directive-which-sets-color-blue>
```
Changes the priority from static binding to interpolated binding which means now the resulting color is `red`. It is very surprising that adding an unrelated interpolation and style can change the `color` which was not changed. To fix that we need to make sure that the static values are associated with priority of the source (directive or template) where they were declared. The new resulting priority is:

```
(least priority)
- Component
  - Static
  - Map/Interpolation
  - Property
- Directives

  - Map/Interpolation

Miško Hevery 9bd9590767 refactor(ivy): change styling to use programmatic API on updates (#34804)
Previously we would write to class/style as strings `element.className` and `element.style.cssText`. Turns out that approach is good for initial render but not good for updates. Updates using this approach are problematic because we have to check to see if there was an out of bound write to style and than perform reconciliation. This also requires the browser to bring up CSS parser which is expensive.

Another problem with old approach is that we had to queue the DOM writes and flush them twice. Once on element advance instruction and once in `hostBindings`. The double flushing is expensive but it also means that a directive can observe that styles are not yet written (they are written after directive executes.)

The new approach uses `element.classList.add/remove` and `element.style.setProperty/removeProperty` API for updates only (it continues to use `element.className` and `element.style.cssText` for initial render as it is cheaper.) The other change is that the styling changes are applied immediately (no queueing). This means that it is the instruction which computes priority. In some circumstances it may result in intermediate writes which are than overwritten with new value. (This should be rare)

Overall this change deletes most of the previous code and replaces it with new simplified implement. The simplification results in code savings.

Miško Hevery 5aabe93abe refactor(ivy): Switch styling to new reconcile algorithm (#34616)
NOTE: This change must be reverted with previous deletes so that it code remains in build-able state.

This change deletes old styling code and replaces it with a simplified styling algorithm.

The mental model for the new algorithm is:
- Create a linked list of styling bindings in the order of priority. All styling bindings ere executed in compiled order and than a linked list of bindings is created in priority order.
- Flush the style bindings at the end of `advance()` instruction. This implies that there are two flush events. One at the end of template `advance` instruction in the template. Second one at the end of `hostBindings` `advance` instruction when processing host bindings (if any).
- Each binding instructions effectively updates the string to represent the string at that location. Because most of the bindings are additive, this is a cheap strategy in most cases. In rare cases the strategy requires removing tokens from the styling up to this point. (We expect that to be rare case)S Because, the bindings are presorted in the order of priority, it is safe to resume the processing of the concatenated string from the last change binding.

Miško Hevery 2961bf06c6 refactor(ivy): move `hostVars`/`hostAttrs` from instruction to `DirectiveDef` (#34683)
This change moves information from instructions to declarative position:
- `ɵɵallocHostVars(vars)` => `DirectiveDef.hostVars`
- `ɵɵelementHostAttrs(attrs)` => `DirectiveDef.hostAttrs`

When merging directives it is necessary to know about `hostVars` and `hostAttrs`. Before this change the information was stored in the `hostBindings` function. This was problematic, because in order to get to the information the `hostBindings` would have to be executed. In order for `hostBindings` to be executed the directives would have to be instantiated. This means that the directive instantiation would happen before we had knowledge about the `hostAttrs` and as a result the directive could observe in the constructor that not all of the `hostAttrs` have been applied. This further complicates the runtime as we have to apply `hostAttrs` in parts over many invocations.

`ɵɵallocHostVars` was unnecessarily complicated because it would have to update the `LView` (and Blueprint) while existing directives are already executing. By moving it out of `hostBindings` function we can access it statically and we can create correct `LView` (and Blueprint) in a single pass.

This change only changes how the instructions are generated, but does not change the runtime much. (We cheat by emulating the old behavior by calling `ɵɵallocHostVars` and `ɵɵelementHostAttrs`) Subsequent change will refactor the runtime to take advantage of the static information.

This commit fixes a compatibility bug where pre-order lifecycle
hooks (onInit, doCheck, OnChanges) for directives on the same
host node were executed based on the order the directives were
matched, rather than the order the directives were instantiated
(i.e. injection order).

This discrepancy can cause issues with forms, where it is common
to inject NgControl and try to extract its control property in
ngOnInit. As the NgControl directive is injected, it should be
instantiated before the control value accessor directive (and
thus its hooks should run first). This ensures that the NgControl
ngOnInit can set up the form control before the ngOnInit
for the control value accessor tries to access it.

Pawel Kozlowski 04b12fc0d6 refactor(ivy): remove isRootView check from getRenderParent (#33988)
The root view case is already covered by the existing code in the
getRenderParent function so no need to have an explicit checks
(and associated memory reads) again.

Pawel Kozlowski 8555d51bc7 perf(ivy): extract template's instruction first create pass processing (#33856)
This refactorings clearly separates the first and subsequent creation execution
of the `template` instruction. This approach has the following benefits:
- it is clear what happens during the first vs. subsequent executions;
- we can avoid several memory reads and checks after the first creation pass
(there is measurable performance improvement on various benchmarks);
- the template instructions becomes smaller and should become a candidate
for optimisations / inlining faster;

Pete Bacon Darwin 641c671bac fix(core): support `ngInjectableDef` on types with inherited `ɵprov` (#33732)
The `ngInjectableDef` property was renamed to `ɵprov`, but core must
still support both because there are published libraries that use the
older term.

We are only interested in such properties that are defined directly on
the type being injected, not on base classes. So there is a check that
the defintion is specifically for the given type.

Previously if you tried to inject a class that had `ngInjectableDef` but
also inherited `ɵprov` then the check would fail on the `ɵprov` property
and never even try the `ngInjectableDef` property resulting in a failed
injection.

This commit fixes this by attempting to find each of the properties
independently.

Pete Bacon Darwin e511bfcab5 fix(ivy): ensure that the correct `document` is available (#33712)
Most of the use of `document` in the framework is within
the DI so they just inject the `DOCUMENT` token and are done.

Ivy is special because it does not rely upon the DI and must
get hold of the document some other way. There are a limited
number of places relevant to ivy that currently consume a global
document object.

The solution is modelled on the `LOCALE_ID` approach, which has
`getLocaleId()` and `setLocaleId()` top-level functions for ivy (see
`core/src/render3/i18n.ts`).  In the rest of Angular (i.e. using DI) the
`LOCALE_ID` token has a provider that also calls setLocaleId() to
ensure that ivy has the same value.

This commit defines `getDocument()` and `setDocument() `top-level
functions for ivy. Wherever ivy needs the global `document`, it calls
`getDocument()` instead.  Each of the platforms (e.g. Browser, Server,
WebWorker) have providers for `DOCUMENT`. In each of those providers
they also call `setDocument()` accordingly.

Miško Hevery c25503b142 test(ivy): Have more descriptive names for `LView` (#33449)
When debugging `LView`s it is easy to get lost since all of them have
the same name. This change does three things:

1. It makes `TView` have an explicit type:
  - `Host`: for the top level `TView` for bootstrap
  - `Component`: for the `TView` which represents components template
  - `Embedded`: for the `TView` which represents an embedded template
2. It changes the name of `LView` to `LHostView`, `LComponentView`, and
  `LEmbeddedView` depending on the `TView` type.
3. For `LComponentView` and `LEmbeddedView` we also append the name of
  of the `context` constructor. The result is that we have `LView`s which
  are name as: `LComponentView_MyComponent` and `LEmbeddedView_NgIfContext`.

The above changes will make it easier to understand the structure of the
application when debugging.

NOTE: All of these are behind `ngDevMode` and will get removed in
production application.

Greg Magolan 1c22e464b2 build: remove deps on legacy nodejs rules rollup_bundle internals (#33201) (#33607)
The legacy nodejs rules rollup_bundle is now deprecated and will be removed in the nodejs rules 1.0 release due in mid-November. This PR brings in the rules_nodejs internal API deps that ng_rollup_bundle, ng_package and ls_rollup_bundle depend on into this repo to break the dependency. In the future these rules should switch to use the new rollup_bundle via a macro as done in https://github.com/angular/angular/pull/33329 but this is not possible right now due to the complication of having esm5 re-rooted ts_library dependencies.

The es6 sources now have .mjs extensions so they no longer need to be re-rooted to `{package}.es6`. This eliminates the need for the collect_es6_sources() function.

Note: repo has been updated to the newest working version of rollup which is 1.25.2. There is some regression in 1.26.0 which causes the following bundling failure:

Will leave that for another day.

Terser also updated to 4.3.3. Updating to 4.3.4 (https://github.com/terser/terser/blob/master/CHANGELOG.md) turns comments preservation on by default which increases the size of the //packages/core/test/bundling/todo:bundle.min.js in CI. After bazelbuild/rules_nodejs#1317 terser can be updated to the latest as passing —comments /a^/ to args can turn off all comments for the //packages/core/test/bundling/todo:bundle.min.js size test.
