This commit fixes the issue of the ASSERTION ERROR issue when
a projected node(RNode) inside an array is checked against the types
of TNodeType.Element, TNodeType.Container, TNodeType.ElementContainer,
TNodeType.IcuContainer, TNodeType.Projection. As it's inside an array,
it doesn't fall into any of those types, as a result, it throws
the ASSERTION ERROR.

When using the [timeout attribute](https://xhr.spec.whatwg.org/#the-timeout-attribute) and an XHR
request times out, browsers trigger the `timeout` event (and execute the XHR's `ontimeout`
callback). Additionally, Safari 9 handles timed-out requests in the same way, even if no `timeout`
has been explicitly set on the XHR.
In the above cases, `HttpClient` would fail to capture the XHR's completing (with an error), so
the corresponding `Observable` would never complete.

When the downleveling helper function has been inlined into the
`$localize` call, it is a bit more tricky to parse out the cooked and
raw strings. There was already code to do this but it assumed that
the `cooked` and `raw` items were both arrays.
Sometimes the `raw` array is just a copy of the `cooked` array
via an expression similar to `raw || (raw=tcookedslice(0))`. This
commit changes the `unwrapMessagePartsFromLocalizeCall()`
function to be able to handle such a situation.

Currently zone.js patches `setTimeout` and keeps a `tasksByHandleId` map to keep `timerId` <-> `ZoneTask`
relationship. This is needed so that when `clearTimeout(timerId)` is called, zone.js can find the associated
`ZoneTask`. Now zone.js set the `tasksByHandleId` map in the `scheduleTask` function, but if the `setTimeout`
is running in the `FakeAsyncZoneSpec` or any other `ZoneSpec` with `onScheduleTask` hooks. The `scheduleTask`
in `timer` patch may not be invoked.
For example:
```
fakeAsync(() => {
setTimeout(() => {});
tick();
});
```
In this case, the `timerId` kept in the `tasksByHandleId` map is not cleared.
This is because the `FakeAsyncZoneSpec` in the `onScheduleTask` hook looks like this.
```
onScheduleTask(delegate, ..., task) {
fakeAsyncScheduler.setTimeout(task);
return task;
}
```
Because `FakeAsyncZoneSpec` handles the task itself and it doesn't call `parentDelegate.onScheduleTask`,
therefore the default `scheduleTask` in the `timer` patch is not invoked.
In this commit, the cleanup logic is moved from `scheduleTask` to `setTimeout` patch entry to
avoid the memory leak.

Two motivations behind this change:
1. We would like to expose the types of the Language Service to external
users (like the VSCode extension) via the npm package, on the top
level of the package
2. We would like the View Engine and Ivy LS to share a common interface
(notably after the inclusion of `getTcb`, the Ivy LS upholds a
strict superset of `ts.LanguageService`; previously both VE and Ivy
LS were aligned on `ts.LanguageService`.)
To this end, this commit refactors the exports on the toplevel of the
`language-service/` package to just be types common to both the VE and
Ivy language services. The VE and Ivy build targets then import and use
these types accordingly, and the expectation is that an external user
will just import the relevant typings from the toplevel package without
diving into either the VE or Ivy sources.

The `TemplateTypeChecker.overrideComponentTemplate` operation was originally
conceived as a "fast path" for the Language Service to react to a template
change without needing to go through a full incremental compilation step. It
served this purpose until the previous commit, which switches the LS to use
the new resource-only incremental change operation provided by `NgCompiler`.
`overrideComponentTemplate` is now no longer utilized, and is known to have
several hard-to-overcome issues that prevent it from being useful in any
other situations. As such, this commit removes it entirely.

Normally the template parsing operation normalizes all template line endings
to '\n' only. This normalization operation causes source mapping errors when
the original template uses '\r\n' line endings.
The compiler already parses templates again to create a "diagnostic"

When setting `ngZoneRunCoalescing` to true, `onStable` is not emitted correctly.
The reason is before this commit, the code looks like this
```
// Application code call `ngZone.run()`
ngZone.run(() => {}); // step 1
// Inside NgZone, in the OnInvoke hook, NgZone try to delay the checkStable()
function delayChangeDetectionForEvents(zone: NgZonePrivate) {
if (zone.lastRequestAnimationFrameId !== -1) { // step 9
return;
}
zone.lastRequestAnimationFrameId = zone.nativeRequestAnimationFrame.call(global, () => { // step 2
if (!zone.fakeTopEventTask) {
zone.fakeTopEventTask = Zone.root.scheduleEventTask('fakeTopEventTask', () => {
zone.lastRequestAnimationFrameId = -1; // step 3
updateMicroTaskStatus(zone); // step 4
checkStable(zone); // step 6
}, undefined, () => {}, () => {});
}
zone.fakeTopEventTask.invoke();
});
updateMicroTaskStatus(zone);
}
function updateMicroTaskStatus(zone: NgZonePrivate, ignoreCheckRAFId = false) {
if (zone._hasPendingMicrotasks ||
((zone.shouldCoalesceEventChangeDetection || zone.shouldCoalesceRunChangeDetection) &&
zone.lastRequestAnimationFrameId !== -1)) { // step 5
zone.hasPendingMicrotasks = true;
} else {
zone.hasPendingMicrotasks = false;
}
}
function checkStable(zone: NgZonePrivate) {
if (zone._nesting == 0 && !zone.hasPendingMicrotasks && !zone.isStable) { // step 7
try {
zone._nesting++;
zone.onMicrotaskEmpty.emit(null);
...
}
// application ref subscribe onMicroTaskEmpty
ngZone.onMicroTaskEmpty.subscribe(() => {
ngZone.run(() => { // step 8
tick();
});
});
```
And the process is:
1. step 1: application call ngZone.run()
2. step 2: NgZone delay the checkStable() call in a requestAnimationFrame, and also set
zone.lastRequestAnimationFrameId
3. step 3: Inside the requestAnimationFrame callback, reset zone.lastRequestAnimationFrameId first
4. step 4: update microTask status
5, step 5: if zone.lastRequestAnimationFrameId is -1, that means no microTask pending.
6. step 6: checkStable and trigger onMicrotaskEmpty emitter.
7. step 7: ApplicationRef subscribed onMicrotaskEmpty, so it will call another `ngZone.run()` to process
tick()
8. step 8: And this new `ngZone.run()` will try to check `zone.lastRequestAnimationFrameId` in `step 9`
when trying to delay the checkStable(), and since the zone.lastRequestAnimationFrameId is already reset
to -1 in step 3, so this ngZone.run() will run into step 2 again.
9. And become a infinite loop..., so onStable is never emit
In this commit, the `zone.lastRequestAnimationFrameId` reset is moved after `checkStable()` call.

If the template parse option `leadingTriviaChars` is configured to
consider whitespace as trivia, any trailing whitespace of an element
would be considered as leading trivia of the subsequent element, such
that its `start` span would start _after_ the whitespace. This means
that the start span cannot be used to mark the end of the current
element, as its trailing whitespace would then be included in its span.
Instead, the full start of the subsequent element should be used.
To harden the tests that for the Ivy parser, the test utility `parseR3`
has been adjusted to use the same configuration for `leadingTriviaChars`
as would be the case in its production counterpart `parseTemplate`. This
uncovered another bug in offset handling of the interpolation parser,
where the absolute offset was computed from the start source span
(which excludes leading trivia) whereas the interpolation expression
would include the leading trivia. As such, the absolute offset now also
uses the full start span.

To prepare for the optimization of template-only changes, this commit
refactors the `ComponentDecoratorHandler`'s handling of template parsing.
Previously, templates were extracted from the raw decorator metadata and
parsed in a single operation.
To better handle incremental template updates, this commit splits this
operation into a "declaration" step where the template info is extracted
from the decorator metadata, and a "parsing" step where the declared
template is read and parsed. This allows for re-reading and re-parsing of
the declared template at a future point, using the same template declaration
extracted from the decorator.

Previously, the incremental flow for NgCompiler was simple: when creating a
new NgCompiler instance, the consumer could pass state from a previous
compilation, which would cause the new compilation to be performed
incrementally. "Local" information about TypeScript files which had not
changed would be passed from the old compilation to the new and reused,
while "global" information would always be recalculated.
However, this flow could be made more efficient in certain cases, such as
when no TypeScript files are changed in a new compilation. In this case,
_all_ information extracted during the first compilation is reusable. Doing
this involves reusing the previous `NgCompiler` instance (the container for
such global information) and updating it, instead of creating a new one for
the next compilation. This approach works cleanly, but complicates the
lifecycle of `NgCompiler`.
To prevent consumers from having to deal with the mechanics of reuse vs
incremental steps of `NgCompiler`, a new `CompilationTicket` mechanism is
added in this commit. Consumers obtain a `CompilationTicket` via one of
several code paths depending on the nature of the incoming compilation, and
use the `CompilationTicket` to obtain an `NgCompiler` instance. This
instance may be a fresh compilation, a new `NgCompiler` for an incremental
compilation, or an existing `NgCompiler` that's been updated to optimally
process a resource-only change. Consumers can use the new `NgCompiler`
without knowledge of its provenance.

The Language Service uses the source span of AST nodes to recognize which
node a user has selected, given their cursor position in a template. This is
used to trigger autocompletion.
The previous source span of BindingPipe nodes created a problem when:
1) the pipe binding had no identifier (incomplete or in-progress expression)
2) the user typed trailing whitespace after the pipe character ('|')
For example, the expression `{{foo | }}`. If the cursor preceded the '}' in
that expression, the Language Service was unable to detect that the user was
autocompleting the BindingPipe expression, since the span of the BindingPipe
ended after the '|'.
This commit changes the expression parser to expand the span of BindingPipe
expressions with a missing identifier, to include any trailing whitespace.
This allows the Language Service to correctly recognize this case as
targeting the BindingPipe and complete it successfully. The `nameSpan` of
the BindingPipe is also moved to be right-aligned with the end of any
whitespace present in the pipe binding expression.
This change allows for the disabled test in the Language Service for pipe
completion in this case to be re-enabled.

This commit reverts commit [_fix(service-worker): handle error with
ErrorHandler_](https://github.com/angular/angular/pull/39990/commits/552419d).
With Angular v11.0.4 and commit [_fix(service-worker): handle error with
ErrorHandler_](https://github.com/angular/angular/pull/39990/commits/552419d)
Angular start to send all service worker registration errors to the Angular
standard `ErrorHandler#handleError()` interface, instead of logging them in the
console.
But users existing `ErrorHandler#handleError()` implementations are not adapted
to service worker registration errors and it might result in broken apps or
bad UI.
Passing to `ErrorHandler` is desirable for some and undesirable for others and
the same is true for passing to `console.error()`.
But `console.error()` was used for a long time and thus it is preferable to keep
it as long as a good solution is not found with `ErrorHandler`.
Right now it's hard to define a good solution for `ErrorHandler` because:
1. Given the nature of the SW registration errors (usually outside the control
of the developer, different error messages on each browser/version, often
quite generic error messages, etc.), passing them to the `ErrorHandler` is
not particularly helpful.
2. While `ErrorHandler#handleError()` accepts an argument of type `any` (so
theoretically we could pass any object without changing the public API), most
apps expect an `Error` instance, so many apps could break if we changed the
shape.
3. Ideally, the Angular community want to re-think the `ErrorHandler` API
and add support for being able to pass additional metadata for each error
(such as the source of the error or some identifier, etc.). This change,
however, could potentially affect many apps out there, so the community must
put some thought into it and design it in a way that accounts for the needs
of all packages (not just the SW).
4. Given that we want to more holistically revisit the `ErrorHandler` API, any
changes we make in the short term to address the issue just for the SW will
make it more difficult/breaky for people to move to a new API in the future.

When a source-map has an inline source, any source-map linked from
that source should only be loaded if itself is also inline; it should not
attempt to load a source-map from the file-system. Otherwise we can
find ourselves with inadvertent infinite cyclic dependencies.
For example, if a transpiler takes a file (e.g. index.js) and generates
a new file overwriting the original file - capturing the original
source inline in the new source-map (index.js.map) - the source
file loader might read the inline original file (also index.js) and
then try to load the `index.js.map` file from disk - ad infinitum.
Note that the first call to `loadSourceFile()` is special, since you can
pass in the source-file and source-map contents directly as in-memory
strrngs. This is common if the transpiler has just generated these and has
not yet written them to disk.
When the contents are passed into `loadSourceFile()` directly, they are
not treated as "inline" for the purposes described above since there is
no chance of these "in-memory" source and source-map contents being caught
up in a cyclic dependency.

PR Close#40489

the exact bloom bucket which is responsible for storing any given 32-bit

and three branches to derive the bloom bucket offset.
This commit exploits the observation that all bits beyond the low 5 bits
of the bloom hash are an accurate representation for the bucket offset,

This reduces the three bitmask operations and three branches with a

However, https://github.com/angular/angular/pull/39917 accidentally leaked
the platform-specific paths, and caused a mismatch between the incoming paths
and the paths stored in the internal data structure `fileToComponent`.
This PR fixes the bug by always normalizing the paths, and updating the
type to reflect the format of the underlying data.

The initial implementation assumed that the consuming editors would
de-duplicate rename locations. In fact, vscode treats overlapping rename
locations as distinct and errors when trying to preview the renames.
This commit updates the language service to de-duplicate exact file+span
matches before returning rename and reference locations.
While vscode _does_ de-duplicate reference results, it still makes sense
to de-duplicate them on our side when possible to make tests more
understandable. If a template has 3 instances of a variable, it makes
sense to get get 3 reference results rather than 4+ with some duplicates.

The current "go to definition" is broken for template variables and
references when a template is overridden. This is because we get the
file url from the source span, which uses the overridden name
'override.html'. Instead, we can retrieve the template file from the
compiler in the same manner that is done for references.
Another way to fix this would have been to use the real template file path when
overriding a template, but this was the more straightforward fix since
the strategy was already used in find references and rename locations.

When a form is reset, it goes through `_forEachChild` to call `reset` on each of its children.
The problem is that if a control is removed while the loop is running (e.g. by a subscription),
the form will throw an error, because it built up the list of available control before the loop
started.
These changes fix the issue by adding a null check before invoing the callback.

`fesm2015/zone.js` is built to `esm` bundle with rollup, so the 'use strict';
statement is not generated in the bundle, even we put the 'use strict' in the src code,
rollup removes the code in the final bundle.
So if we load the `fesm2015/zone.js` as a module, such as `ng serve`, in the index.html
```
<script src="polyfills.js" type="module"></script>
```
Everything works fine, since polyfills.js is loaded as `module`, so it is always `strict`.
But in `ng test`, webpack concat the `zone.js` and loaded into the karma html. For other app and
test code, they are still `strict` since they are `module` because they have `export/import`
statement, but `zone.js` is a bundle without `export`, it is a `side effect` bundle, so after
loaded by webpack, it becomes non-strict. Which causes some issues, such as #40215,
the root cause is the `this` context should be `undefined` but treated as `Window` in `non-strict` mode.
```
Object.prototype.toString.apply(undefined);
// should be [object undefined], but it is [object Window] in non-strict mode.
// zone.js patched version of toString
Object.prototype.toString = function() {
...
// in non-strict mode, this is Window
return originalObjectPrototypeToString.call(this);
}
```
So in this commit, `'use strict';` is always added to the `esm` bundles.

This commit lays the groundwork for potentially providing rename
locations from the Ivy native LS. The approach is very similar to what
was done with the feature to find references. One difference, however,
is that we did not require the references to be fully "correct". That
is, the exact text spans did not matter so much, as long as we provide a
location that logically includes the referenced item.
An example of a necessary difference between rename locations and references is
directives. The entire element in the template is a "reference" of the
directive's class. However, it's not a valid location to be renamed. The
same goes for aliased inputs/outputs. The locations in the template
directly map to the class property, which is correct for references, but
would not be correct for rename locations, which should instead map to
the string node fo the alias.
As an initial approach to address the aforementioned issues with rename
locations, we check that all the rename location nodes have the same text. If
_any_ node has text that differs from the request, we do not return any
rename locations. This works as a way to prevent renames that could
break the the program by missing some required nodes in the rename action, but
allowing other nodes to be renamed.

Currently when analyzing the metadata of a directive, we bundle together the bindings from `host`
and the `HostBinding` and `HostListener` together. This can become a problem later on in the
compilation pipeline, because we try to evaluate the value of the binding, causing something like
`@HostBinding('class.foo') public true = 1;` to be treated the same as
`host: {'[class.foo]': 'true'}`.
While looking into the issue, I noticed another one that is closely related: we weren't treating
quoted property names correctly. E.g. `@HostBinding('class.foo') public "foo-bar" = 1;` was being
interpreted as `classProp('foo', ctx.foo - ctx.bar)` due to the same issue where property names
were being evaluated.
These changes resolve both of the issues by treating all `HostBinding` instance as if they're
reading the property from `this`. E.g. the `@HostBinding('class.foo') public true = 1;` from above
is now being treated as `host: {'[class.foo]': 'this.true'}` which further down the pipeline becomes
`classProp('foo', ctx.true)`. This doesn't have any payload size implications for existing code,
because we've always been prefixing implicit property reads with `ctx.`. If the property doesn't
have an identifier that can be read using dotted access, we convert it to a quoted one (e.g.
`classProp('foo', ctx['is-foo']))`.

This commit updates the `recognize` algorithm to work with named outlets
which have empty path parents. For example, given the following config
```
const routes = [
{
path: '',
children: [
{path: 'a', outlet: 'aux', component: AuxComponent}
]}
];
```
The url `/(aux:a)` should match this config. In order to do so, we need
to allow the children of `UrlSegmentGroup`s to match a `Route` config
for a different outlet (in this example, the `primary`) when it's an
empty path. This should also *only* happen if we were unable to find a
match for the outlet in the level above. That is, the matching strategy
is to find the first `Route` in the list which _matches the given
outlet_. If we are unable to do that, then we allow empty paths from
other outlets to match and try to find some child there whose outlet
matches our segment.

Internally we store lifecycle hooks in the format `[index, hook, index, hook]` and when

This commit fixes an issue in the ivy native language service
that caused the logic that finds a target node given a template
position to throw away the results. This happened because the
source span of a variable node in the shorthand structural
directive syntax (i.e. `*ngIf=`) included the entire binding.
The result was that we would add the variable node to the path and then
later detect that the cursor was outside the key and value spans and
throw away the whole result. In general, we do this because we do not
want to show information when the cursor is between a key/value
(`inputA=¦"123"`). However, when using the shorthand syntax, we run into
the situation where we can match an `AttributeBinding` as well as the
vaariable in `*ngIf="som¦eValue as myLocalVar"`. This commit updates the
visitor to retain enough information in the visit path to throw away
invalid targets but keep valid ones if there were multiple results on a

Escape the content of the strings so that it can be safely inserted into a comment node.
The issue is that HTML does not specify any way to escape comment end text inside the comment.
`<!-- The way you close a comment is with "-->". -->`. Above the `"-->"` is meant to be text
not an end to the comment. This can be created programmatically through DOM APIs.
```
div.innerHTML = div.innerHTML

One would expect that the above code would be safe to do, but it turns out that because comment
text is not escaped, the comment may contain text which will prematurely close the comment
opening up the application for XSS attack. (In SSR we programmatically create comment nodes which
may contain such text and expect them to be safe.)
This function escapes the comment text by looking for the closing char sequence `-->` and replace
it with `-_-_>` where the `_` is a zero width space `\u200B`. The result is that if a comment
contains `-->` text it will render normally but it will not cause the HTML parser to close the

First is that the tests in compliace_old expected an expection to be be

that this test could miss catching a bug. It is also a big hacky to call
compile directly and expect an exception to be thrown for diagnostics.
Also, this can easily be unit tested and an end-to-end test is not
necessary since we are not making use of the goldfiles for these tests.

This commit introduces an `isStructural` flag on directive metadata, which

from 3 sources:
1. inputs/outputs of directives currently present on the element
2. inputs/outputs/attributes of directives in scope for the element, that
would become present if the input/output/attribute was added
3. DOM properties and attributes
We distinguish between completion of a property binding (`[foo|]`) and a
completion in an attribute context (`foo|`). For the latter, bindings to
the attribute are offered, as well as a property binding which adds the
square bracket notation.
To determine hypothetical matches (directives which would become present if
a binding is added), directives in scope are scanned and matched against a
hypothetical version of the element which has the attribute.

Projects opened in the LS are often larger in scope than the compilation
units seen by the compiler when actually building. For example, in the LS
it's not uncommon for the project to include both application as well as
test files. This can create issues when the combination of files results
in errors that are not otherwise present - for example, if test files
have inline NgModules that re-declare components (a common Angular pattern).
Such code is valid when compiling the app only (test files are excluded, so
only one declaration is seen by the compiler) or when compiling tests only
(since tests run in JIT mode and are not seen by the AOT compiler), but when
both sets of files are mixed into a single compilation unit, the compiler
sees the double declaration as an error.
This commit attempts to mitigate the problem by forcing the compiler flag
`compileNonExportedClasses` to `false` in a LS context. When tests contain
duplicate declarations, often such declarations are inline in specs and not
exported from the top level, so this flag can be used to greatly improve the
IDE experience.
