This patch changes the Ivy `DebugElement` code to always read style and
class values directly from the native element instead of reading them
through the styling contexts. The reason for this change is because Ivy
does not make use of a debug renderer and will therefore not have access
to any classes/styles applied directly through the renderer (unless it
reads the values directly from the element).

Prior to this commit, the `ngProjectAs` attribute was only included with a special flag and in a parsed format. As a result, projected node was missing `ngProjectAs` attribute as well as other attributes added after `ngProjectAs` one. This is problematic since app code might rely on the presence of `ngProjectAs` attribute (for example in CSS). This commit fixes the problem by including `ngProjectAs` into attributes array as a regular attribute and also makes sure that the parsed version of the `ngProjectAs` attribute with a special marker is added after regular attributes (thus we set them correctly at runtime). This change also aligns View Engine and Ivy behavior.

Now that the `$localize` translations are `MessageId` based the
compiler must render `MessageId`s in its generated `$localize` code.
This is because the `MessageId` used by the compiler is computed
from information that does not get passed through to the `$localize`
tagged string.
For example, the generated code for the following template
```html
<div id="static" i18n-title="m|d" title="introduction"></div>
```
will contain these localization statements
```ts
if (ngI18nClosureMode) {
/**
* @desc d
* @meaning m
*/
const MSG_EXTERNAL_8809028065680254561$$APP_SPEC_TS_1 = goog.getMsg("introduction");
I18N_1 = MSG_EXTERNAL_8809028065680254561$$APP_SPEC_TS_1;
}
else {
I18N_1 = $localize \`:m|d@@8809028065680254561:introduction\`;
}
```
Since `$localize` is not able to accurately regenerate the source-message
(and so the `MessageId`) from the generated code, it must rely upon the
`MessageId` being provided explicitly in the generated code.
The compiler now prepends all localized messages with a "metadata block"
containing the id (and the meaning and description if defined).
Note that this metadata block will also allow translation file extraction
from the compiled code - rather than relying on the legacy ViewEngine
extraction code. (This will be implemented post-v9).
Although these metadata blocks add to the initial code size, compile-time
inlining will completely remove these strings and so will not impact on
production bundle size.

Prior to this patch, each time `advance()` would run (or when a

code would check to see whether the styling data needs to be reset. This

This is a refactoring that moves the source code around to provide a better
platform for adding the compile-time inlining.
1. Move the global side-effect import from the primary entry-point to a
secondary entry-point @angular/localize/init.
This has two benefits: first it allows the top level entry-point to
contain tree-shakable shareable code; second it gives the side-effect
import more of an "action" oriented name, which indicates that importing
it does something tangible
2. Move all the source code into the top src folder, and import the localize
related functions into the localize/init/index.ts entry-point.
This allows the different parts of the package to share code without
a proliferation of secondary entry-points (i.e. localize/utils).
3. Avoid publicly exporting any utilities at this time - the only public
API at this point are the global `$localize` function and the two runtime
helpers `loadTranslations()` and `clearTranslations()`.
This does not mean that we will not expose additional helpers for 3rd
party tooling in the future, but it avoid us preemptively exposing
something that we might want to change in the near future.
Notes:
It is not possible to have the `$localize` code in the same Bazel package
as the rest of the code. If we did this, then the bundled `@angular/localize/init`
entry-point code contains all of the helper code, even though most of it is not used.
Equally it is not possible to have the `$localize` types (i.e. `LocalizeFn`
and `TranslateFn`) defined in the `@angular/localize/init` entry-point because
these types are needed for the runtime code, which is inside the primary
entry-point. Importing them from `@angular/localize/init` would run the
side-effect.
The solution is to have a Bazel sub-package at `//packages/localize/src/localize`
which contains these types and the `$localize` function implementation.
The primary `//packages/localize` entry-point imports the types without
any side-effect.
The secondary `//packages/localize/init` entry-point imports the `$localize`
function and attaches it to the global scope as a side-effect, without
bringing with it all the other utility functions.
BREAKING CHANGES:
The entry-points have changed:
* To attach the `$localize` function to the global scope import from
`@angular/localize/init`. Previously it was `@angular/localize`.
* To access the `loadTranslations()` and `clearTranslations()` functions,
import from `@angular/localize`. Previously it was `@angular/localize/run_time`.

Prior to this commit, listeners order was not preserved in case we coalesce them to avoid triggering unnecessary change detection cycles. For performance reasons we were attaching listeners to existing events at head (always using first listener as an anchor), to avoid going through the list, thus breaking the order in which listeners are registered. In some scenarios this order might be important (for example with `ngModelChange` and `input` listeners), so this commit updates the logic to put new listeners at the end of the list.

BREAKING CHANGE
Since `$localize` is a global function, it must be included in any applications
that use i18n. This is achieved by importing the `@angular/localize` package
into an appropriate bundle, where it will be executed before the renderer
needs to call `$localize`. For CLI based projects, this is best done in
the `polyfills.ts` file.

import '@angular/localize';

file or another suitable script file.

Angular hooks come after 2 flavours:
- init hooks (OnInit, AfterContentInit, AfterViewInit);
- check hooks (OnChanges, DoChanges, AfterContentChecked, AfterViewChecked).
We need to do more processing for init hooks to ensure that those hooks
are run once and only once for a given directive (even in case of errors).
As soon as all init hooks execute to completion we are only left with the
checks to execute.
It turns out that keeping track of the remaining init hooks to execute is
rather expensive (multiple LView flags reads, writes and checks). But we can
observe that non of this tracking is needed as soon as all init hooks are
completed.
This PR takes advantage of the above observations and splits hooks processing
functions into:
- init-specific (slower but less common);
- check-specific (faster and more common).

In VE the `Sanitizer` is always available in `BrowserModule` because the VE retrieves it using injection.
In Ivy the injection is optional and we have instructions instead of component definition arrays. The implication of this is that in Ivy the instructions can pull in the sanitizer only when they are working with a property which is known to be unsafe. Because the Injection is optional this works even if no Sanitizer is present. So in Ivy we first use the sanitizer which is pulled in by the instruction, unless one is available through the `Injector` then we use that one instead.
This PR does few things:
1) It makes `Sanitizer` optional in Ivy.
2) It makes `DomSanitizer` tree shakable.
3) It aligns the semantics of Ivy `Sanitizer` with that of the Ivy sanitization rules.
4) It refactors `DomSanitizer` to use same functions as Ivy sanitization for consistency.

In ViewEngine nodes that were inserted through `Renderer2` would also be picked up by `DebugNode.query` and `DebugNode.queryAll`. This worked because everything in ViewEngine went through `Renderer2` and `DebugRenderer2` in dev mode which was able to keep track of the child nodes as they're being inserted. This no longer works in Ivy, because we don't use `DebugRenderer2` and debug nodes work a little differently. These changes work around the issue by walking the DOM as the logical tree is being walked and looking for matches. Note that this is __not__ optimal, because we're walking similar trees multiple times. ViewEngine could do it more efficiently, because all the insertions go through Renderer2, however that's not the case in Ivy. This approach is being used because:
1. Matching the ViewEngine behavior would mean potentially introducing a depedency from `Renderer2` to Ivy which could bring Ivy code into ViewEngine.
2. We would have to make `Renderer3` "know" about debug nodes.
3. It allows us to capture nodes that were inserted directly via the DOM.

Currently we reuse the same instruction both for regular property bindings and property bindings on the `host`. The only difference between the two is that when it's on the host we shouldn't support inputs. We have an optional parameter called `nativeOnly` which is used to differentiate the two, however since `nativeOnly` is preceeded by another optional parameter (`sanitizer`), we have to generate two extra parameters for each host property bindings every time (e.g. `property('someProp', 'someValue', null, true)`).
These changes add a new instruction called `hostProperty` which avoids the need for the two parameters by removing `nativeOnly` which is always set and it allows us to omit `sanitizer` when it isn't being used.
These changes also remove the `nativeOnly` parameter from the `updateSyntheticHostBinding` instruction, because it's only generated for host elements which means that we can assume that its value will always be `true`.

These changes also add an error if an interpolation is encountered inside a `style` tag (e.g. `style="width: {{value}}"`). Up until now this would actually generate valid instructions, because `styleMap` goes through the same code path as `classMap` which does support interpolation. At runtime, however, `styleMap` would set invalid styles that look like `<div style="0:w;1:i;2:d;3:t;4:h;5::;7:1;">`. In `ViewEngine` interpolations inside `style` weren't supported either, however there we'd output invalid styles like `<div style="unsafe">`, even if the content was trusted.

Currently in Ivy whenever we encounter a new namespace, we set it in the global state so that all subsequent nodes are created under the same namespace. Next time a template is run the namespace will be reset back to HTML.
This breaks down if the last node that was rendered was under the SVG or MathML namespace and we create a component through `ViewContainerRef.create`, because the next template function hasn't run yet and it hasn't had the chance to update the namespace. The result is that the root node of the new component will retain the wrong namespace and may not end up rendering at all (e.g. if we're trying to show a `div` inside the SVG namespace). This issue has the potential to affect a lot of apps, because all components inserted through the router also go through `ViewContainerRef.create`.

The Angular runtime frequently calls into user code (for example, when
writing to a property binding). Since user code can throw errors, calls to
it are frequently wrapped in a try-finally block. In Ivy, the following
pattern is common:
```typescript
enterView();
try {
callUserCode();
} finally {
leaveView();
}
```
This has a significant problem, however: `leaveView` has a side effect: it
calls any pending lifecycle hooks that might've been scheduled during the
current round of change detection. Generally it's a bad idea to run
lifecycle hooks after the application has crashed. The application is in an
inconsistent state - directives may not be instantiated fully, queries may
not be resolved, bindings may not have been applied, etc. Invariants that
the app code relies upon may not hold. Further crashes or broken behavior
are likely.
Frequently, lifecycle hooks are used to make assertions about these
invariants. When these assertions fail, they will throw and "swallow" the
original error, making debugging of the problem much more difficult.
This commit modifies `leaveView` to understand whether the application is
currently crashing, via a parameter `safeToRunHooks`. This parameter is set
by modifying the above pattern:
```typescript
enterView();
let safeToRunHooks = false;
try {
callUserCode();
safeToRunHooks = true;
} finally {
leaveView(..., safeToRunHooks);
}
```
If `callUserCode` crashes, then `safeToRunHooks` will never be set to `true`
and `leaveView` won't call any further user code. The original error will
then propagate back up the stack and be reported correctly. A test is added
to verify this behavior.

In ViewEngine injecting a Renderer2 returns a renderer that is specific to the particular component, however in Ivy we inject the renderer for the parent view instead. This causes it to set incorrect `ngcontent` attributes when creating elements through the renderer.
The issue comes from the fact that the `Renderer2` is created according to the current `LView`, but because DI happens before we've entered the `LView` of the component that's injecting the renderer, we end up with one that's one level up. We work around the issue by finding the `LView` that corresponds to the `previousOrParentTNode` inside of the parent view and associating the `Renderer2` with it.

To provide some context: The implicit receiver is part of the
parsed Angular template AST. Any property reads in bindings,
interpolations etc. read from a given object (usually the component
instance). In that case there is an _implicit_ receiver which can also
be specified explicitly by just using `this`.
e.g.
```html
<ng-template>{{this.myProperty}}</ng-template>
```
This works as expected in Ivy and View Engine, but breaks in case the
implicit receiver is not used for property reads. For example:
```html
<my-dir [myFn]="greetFn.bind(this)"></my-dir>
```
In that case the `this` will not be properly translated into the generated
template function code because the Ivy compiler currently always treats
the `ctx` variable as the implicit receiver. This is **not correct** and breaks
compatibility with View Engine. Rather we need to ensure that we retrieve
the root context for the standalone implicit receiver similar to how it works
for property reads (as seen in the example above with `this.myProperty`)
Note that this requires some small changes to the `expression_converter`
because we only want to generate the `eenextContent()` instruction if the
implicit receiver is _actually_ used/needed. View Engine determines if that is the case by recursively walking through the converted output AST and
checking for usages of the `o.variable('_co')` variable ([see here][ve_check]). This would work too for Ivy, but involves most likely more code duplication
since templates are isolated in different functions and it another pass
through the output AST for every template expression.

With View engine it was possible to declare multiple projection
definitions and to programmatically project nodes into the slots.
e.g.
```html
<ng-content></ng-content>
<ng-content></ng-content>
```
Using `ViewContainerRef#createComponent` allowed projecting
nodes into one of the projection defs (through index)
This no longer works with Ivy as the `projectionDef` instruction only
retrieves a list of selectors instead of also retrieving entries for
reserved projection slots which appear when using the default
selector multiple times (as seen above).
In order to fix this issue, the Ivy compiler now passes all
projection slots to the `projectionDef` instruction. Meaning that
there can be multiple projection slots with the same wildcard
selector. This allows multi-slot projection as seen in the
example above, and it also allows us to match the multi-slot node
projection order from View Engine (to avoid breaking changes).
It basically ensures that Ivy fully matches the View Engine behavior
except of a very small edge case that has already been discussed
in FW-886 (with the conclusion of working as intended).

Two issues with DebugNode/DebugElement in Ivy were causing problems in user
tests.
1. The DebugNodes returned by Ivy were not actually instances of DebugNode.
This was due to an issue with the Ivy switch logic in debug_node.ts.
The declaration of the exported DebugNode reference was set to
`DebugNode__PRE_R3__ as any`. The cast prevented the Ivy switch transform
from detecting this as a switchable declaration. The transform cannot handle
arbitrary syntax, and exports *must* be of the form "const x = y__PRE_R3__;"
or they will not work. The cast to any in this case was not needed, so this
commit removes it.
2. DebugNodes returned by Ivy multiple times for the same element were not
reference-identical. This was previously considered a minor breaking change
in Ivy, but testing has shown that users depend on referential equality of
DebugNodes. This commit caches a DebugNode on a DOM node when first creating
it, to allow returning the same instance in subsequent operations.

Plural ICU expressions depend on the locale (different languages have different plural forms). Until now the locale was hard coded as `en-US`.
For compatibility reasons, if you use ivy with AOT and bootstrap your app with `bootstrapModule` then the `LOCALE_ID` token will be set automatically for ivy, which is then used to get the correct plural form.
If you use JIT, you need to define the `LOCALE_ID` provider on the module that you bootstrap.
For `TestBed` you can use either `configureTestingModule` or `overrideProvider` to define that provider.
If you don't use the compat mode and start your app with `renderComponent` you need to call `ɵsetLocaleId` manually to define the `LOCALE_ID` before bootstrap. We expect this to change once we start adding the new i18n APIs, so don't rely on this function (there's a reason why it's a private export).

This is a new feature of the Ivy TestBed.
A common user pattern is to test one component with another. This is
commonly done by creating a `TestFixture` component which exercises the
main component under test.
This pattern is more difficult if the component under test is declared in an
NgModule but not exported. In this case, overriding the module is necessary.
In g3 (and View Engine), it's possible to use an NgSummary to override the
recompilation of a component, and depend on its AOT compiled factory. The
way this is implemented, however, specifying a summary for a module
effectively overrides much of the TestBed's other behavior. For example, the
following is legal:
```typescript
TestBed.configureTestingModule({
declarations: [FooCmp, TestFixture],
imports: [FooModule],
aotSummaries: [FooModuleNgSummary],
});
```
Here, `FooCmp` is declared in both the testing module and in the imported
`FooModule`. However, because the summary is provided, `FooCmp` is not
compiled within the context of the testing module, but _is_ made available
for `TestFixture` to use, even if it wasn't originally exported from
`FooModule`.
This pattern breaks in Ivy - because summaries are a no-op, this amounts
to a true double declaration of `FooCmp` which raises an error.
Fixing this in user code is possible, but is difficult to do in an
automated or backwards compatible way. An alternative solution is
implemented in this PR.
This PR attempts to capture the user intent of the following previously
unsupported configuration:
```typescript
TestBed.configureTestingModule({
declarations: [FooCmp, TestFixture],
imports: [FooModule],
});
```
Note that this is the same as the configuration above in Ivy, as the
`aotSummaries` value provided has no effect.
The user intent here is interpreted as follows:
1) `FooCmp` is a pre-existing component that's being used in the test
(via import of `FooModule`). It may or may not be exported by this
module.
2) `FooCmp` should be part of the testing module's scope. That is, it
should be visible to `TestFixture`. This is because it's listed in
`declarations`.
This feature effectively makes the `TestBed` testing module special. It's
able to declare components without compiling them, if they're already
compiled (or configured to be compiled) in the imports. And crucially, the
behavior matches the first example with the summary, making Ivy backwards
compatible with View Engine for tests that use summaries.

With Ivy, injecting a `ViewContainerRef` for a `<ng-container>` element
results in two comments generated in the DOM. One comment as host
element for the `ElementContainer` and one for the generated `LContainer`
which is needed for the created `ViewContainerRef`.
This is problematic as developers expect the same anchor element for
the `LContainer` and the `ElementContainer` in order to be able to move
the host element of `<ng-container>` without leaving the actual
`LContainer` anchor element at the original location.
This worked differently in View Engine and various applications might
depend on the behavior where the `ViewContainerRef` shares the anchor
comment node with the host comment node of the `<ng-container>`. For
example `CdkTable` from `@angular/cdk` moves around the host element of
a `<ng-container>` and also expects embedded views to be inserted next
to the moved `<ng-container>` host element.

* A handful of tests weren't migrated, because they were testing an API that isn't exposed publicly yet.
* The `should throw if bindings in children of current view have changed` and `should NOT throw if bindings in ancestors of current view have changed` tests were removed, because there's not nice way of hitting the same code path with `TestBed` and doing the same assertion as with the raw instructions. I'm open to ideas on how we could do them.
* There were a few tests that assert that the `innerHTML` looks in a particular way. I've switched them to use `textContent`, because Ivy and ViewEngine produce slightly different DOM. The tests were only checking whether the text has changed anyway.

Moves all manual render3 property binding tests to
TestBed acceptance tests. Unfortunately three property
binding tests could not be migrated as these rely on
manual Ivy template code that is not supported within
TestBed. These can be revisited as discussed in the
framework team meeting.
PR Close#30426
Moves all manual render3 tests which are located within the
`renderer_factory_spec.ts` file to acceptance tests. A few tests
that use Ivy-specific logic which is not replicable with `TestBed`
remain in the render3 folder (e.g. using `renderTemplate`)
Additionally migrated tests that assert the lifecycles of the
renderer_factory are set to *ivy only* as the lifecycle seems
to be different in Ivy. Tracked with: FW-1320

Currently in Ivy `NgModule` registration happens when the class is declared, however this is inconsistent with ViewEngine and requires extra generated code. These changes remove the generated code for `registerModuleFactory`, pass the id through to the `ngModuleDef` and do the module registration inside `NgModuleFactory.create`.
This PR resolves FW-1285.

Moves over the tests from `pipe_spec` into `acceptance`. Note that the two `WrappedValue` tests haven't been moved over, because impure pipes always throw "changed after checked" errors in `TestBed`. This seems to be consistent with ViewEngine.

Moves most of the tests in `output_spec` into `acceptance`. Note that one test is left in `render3`, because it's testing mixing in custom logic with instructions which we can't replicate using `TestBed`.

Even though we don't run the size-tracking test on CI
right now, we update the golden size map as part of
the size-tracking tool update. The size-map difference
should generally be kept up-to-date to be able to
determine which PRs contribute size to a given file.
PR Close#30257
Based on discussion that happened on the PR that introduced
the size-tracking tool, we want to have another threshold for
the raw byte difference. This allows us to better control for
which changes the size-tracking tool should report a difference.

We have an issue where we would like to be able to test perf counter metrics in acceptance tests, but we are unable to do so, because it will break when those same tests are run with ViewEngine. This PR adds a testing utility to `onlyInIvy` that allows for testing of performance counters, and even gives readable errors for what value on `ngDevMode` is incorrect. Has typings for decent autocompletion as well.

This is the final patch to migrate the Angular styling code to have a
smaller instruction set in preparation for the runtime refactor. All
styling-related instructions now work both in template and hostBindings
functions and do not use `element` as a prefix for their names:
BEFORE:
elementStyling()
elementStyleProp()
elementClassProp()
elementStyleMap()
elementClassMap()
elementStylingApply()
AFTER:
styling()
styleProp()
classProp()
styleMap()
classMap()
stylingApply()
PR Close#30318
This patch removes all host-specific styling instructions in favor of
using element-level instructions instead. Because of the previous
patches that made sure `select(n)` worked between styling calls, all
host level instructions are not needed anymore. This patch changes each
of those instruction calls to use any of the `elementStyling*`,
`elementStyle*` and `elementClass*` styling instructions instead.

Fixes not being able to bind a `SafeStyle` as a camel cased style property (e.g. `[style.backgroundImage]="someSafeStyle"`). The issue was due to the fact that we only check the dash case property names to determine whether to sanitize a value.
This PR resolves FW-1279.
PR Close#30328
This patch is one commit of many patches that will unify all styling instructions
across both template-level bindings and host-level bindings. This patch in particular
removes the `elementIndex` param because it is already set prior to each styling
instruction via the `select(n)` instruction.
PR Close#30313
This patch breaks up the existing `elementStylingMap` into
`elementClassMap` and `elementStyleMap` instructions. It also breaks
apart `hostStlyingMap` into `hostClassMap` and `hostStyleMap`
instructions. This change allows for better tree-shaking and reduces
the complexity of the styling algorithm code for `[style]` and `[class]`
bindings.

This commit fixes a regression introduced in PR 29692 where
the interpolate symbol in View Engine was improperly prefixed
with the ɵɵ that signifies private instructions for Ivy. It
resulted in interpolations of 10+ values not working correctly
in AOT mode. This commit removes the prefix.

Ivy uses R3Injector, but we are currently pulling in both the StaticInjector
(View Engine injector) and the R3Injector when running with Ivy. This commit
adds an ivy switch so calling Injector.create() pulls in the correct
implementation of the injector depending on whether you are using VE or Ivy.
This saves us about 3KB in the bundle.

Previously, we were supporting injection flags for provider deps, but only

PR Close#30158
Introduces a new Bazel test that allows us to inspect
what source-files contribute to a given bundled file
and how much bytes they contribute to the bundle size.
Additionally the size-tracking rule groups the size
data by directories. This allows us to compare size
changes in the scope of directories. e.g. a lot of
files in a directory could increase slightly in size, but
in the directory scope the size change could be significant
and needs to be reported by the test target.

The `renderStringify` function is used in a lot of performance-sensitive places, however it contains a megamorphic read which is used primarily for error messages. These changes introduce a new function that can be used to stringify output for errors and removes the megamorphic read from `renderStringify`.

Fixes view and content queries not being inherited in Ivy, if the base class hasn't been annotated with an Angular decorator (e.g. `Component` or `Directive`).
Also reworks the way the `ngBaseDef` is created so that it is added at the same point as the queries, rather than inside of the `Input` and `Output` decorators.
This PR partially resolves FW-1275. Support for host bindings will be added in a follow-up, because this PR is somewhat large as it is.

PR Close#30024
Previously, we had a bug where directive matching could fail if the directive
attribute was bound and followed a certain number of classes. This is because
in the matching logic, we were treating classes like normal attributes. We
should instead be skipping classes in the attribute matching logic. Otherwise
classes will match for directives with attribute selectors, and as we are
iterating through them in twos (when they are stored as name-only, not in
name-value pairs), it may throw off directive matching for any bound attributes
that come after. This commit changes the directive matching logic to skip
classes altogether.
PR Close#30002
We only set ng-reflect properties on directive input bindings.

PR Close#29973
Previous to this change, we assumed embedded views could only be created after
their parent template node had completed processing. As a result, we only set
up query logic for containers after directives on the node were created.
However, this assumption didn't take into account the case where a directive
on a template node could create views in its constructor.
This commit fixes query logic to work with views created in constructors.
In that case, we need to create a query container before the new view is
rendered so query results in the view aren't lost. But since the query container
is created before directives have completed processing, we also have to ensure
that query results gathered later on the template node are inserted before that
query container. Otherwise, query results in embedded views will clobber query
results on template nodes.
This splice mode may be slightly slower than the normal matching for queries on
containers, but we should only fall back to this strategy in the edge case where
views are created in constructors. (We should encourage developers to create
views in ngOnInit instead).
PR Close#29983
Prior to this change, components created via TestBed.createComponent in the same test were placed into the same root context, which caused problems in conjunction with fixture.autoDetectChanges usage in the same test. Specifically, change detection was triggered immediately for created component (starting from the 2nd one) even if it was not required/desired. This commit makes Ivy and VE behavior consistent: now every component created via TestBed.createComponent is isolated from each other. Current solution uses host element id naming convention, which is not ideal, but helps avoid public API surface changes at this point (we might revisit this approach later).
Note: this commit also adds extra tests to verify bootstrap and change detection behavior in case of multiple components in `bootstrap` array in @NgModule, to make sure this behavior is aligned between Ivy and VE.
