This exposes a bug in ngcc, where it can only handle functions that have a

In some libraries, the function instead returns a call to another function.

```
InMemoryWebApiModule.forFeature = function (dbCreator, options) {

Previously, in order to remain as deterministic as possible, the

versions unavailable on the repositories once a newer version is
available.

In order to ease local development, self-signed SSL/TLS certificates are
created when building the preview server Docker image. These
certificates are valid for 365 days. Thus, it is possible for an old
certificate to be re-used past its expiration date due to Docker's
caching intermediate layers.
Previously, this would lead to hard-to-debug failures in the
`aio-health-check` and `aio-verify-setup` checks. Even after finding out
that the failures were caused by an expired certificate, it was not
obvious why that would be the case.
This commit adds an additional check to the `aio-health-check` command
that checks the certificates' expiration dates. This helps surface such
errors. It also prints a more helpful message, prompting the user to
build the Docker image with the `--no-cache` option to fix the problem

Previously, in the `test_aio` CI job, we ran ngcc before building the
app with `yarn build`. This was supposed to have the benefit of taking
advantage of the parallel capabilities of standalone ngcc (vs implicitly
running it via `ng build`).
It turns out that the work done by the standalone ngcc was thrown away
before the `ng build`, resulting in `ng build` having to run ngcc all
over again. This happened because the `yarn build` script (run after the
standalone ngcc step) also runs `yarn install`, which essentially cleans
up `node_modules/`, thus discarding all the work already done by ngcc.
Here is an [example CI job][1], where this can be seen in action:
One can see the "Compiling <some-package> : es2015 as esm2015" logs in
the `yarn --cwd aio ngcc --properties es2015` step (as the standalone
ngcc processes the various entry-points) and then see the same logs in
the `yarn --cwd aio build --progress=false` step (as ngcc has to process
the entry-points all over again).
This commit removes the redundant standalone ngcc run and lets the CLI
handle ngcc via `ng build`. It is possible to instrument the build
process in a way that we can run the standalone ngcc after
`yarn install` and thus take advantage of the performance gains in
parallel mode, but the latest version of the CLI can already run ngcc in
parallel mode as a pre-build step, so this is unnecessary.

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

When running in parallel mode, worker processes forward errors thrown
during task processing to the master process, which in turn exits with
an error.
However, there are cases where the error is not directly related to
processing the entry-point. One such case is when there is not enough
memory (for example, due to all the other tasks being processed
simultaneously).
Previously, an `ENOMEM` error thrown on a worker process would propagate
to the master process, eventually causing ngcc to exit with an error.
Example failure: https://circleci.com/gh/angular/angular/682198
This commit improves handling of these low-memory situations by
detecting `ENOMEM` errors and killing the worker process, thus allowing
the master process to decide how to handle that. The master process will
put the task back into the tasks queue and continue processing tasks
with the rest of the worker processes (and thus with lower memory
pressure).
PR Close#36626
Previously, when the last worker process crashed, the master process
would try to re-spawn it indefinitely. This could lead to an infinite
loop (if for some reason the worker process kept crashing).
This commit avoids this by limiting the number of re-spawn attempts to
3, after which ngcc will exit with an error.
PR Close#36626
Previously, when running in parallel mode and a worker process crashed
while processing a task, it was not possible for ngcc to continue
without risking ending up with a corrupted entry-point and therefore it
exited with an error. This, for example, could happen when a worker
process received a `SIGKILL` signal, which was frequently observed in CI
environments. This was probably the result of Docker killing processes
due to increased memory pressure.
One factor that amplifies the problem under Docker (which is often used
in CI) is that it is not possible to distinguish between the available
CPU cores on the host machine and the ones made available to Docker
containers, thus resulting in ngcc spawning too many worker processes.
This commit addresses these issues in the following ways:
1. We take advantage of the fact that files are written to disk only
after an entry-point has been fully analyzed/compiled. The master
process can now determine whether a worker process has not yet
started writing files to disk (even if it was in the middle of
processing a task) and just put the task back into the tasks queue if
the worker process crashes.
2. The master process keeps track of the transformed files that a worker
process will attempt to write to disk. If the worker process crashes
while writing files, the master process can revert any changes and
put the task back into the tasks queue (without risking corruption).
3. When a worker process crashes while processing a task (which can be a
result of increased memory pressure or too many worker processes),
the master process will not try to re-spawn it. This way the number
or worker processes is gradually adjusted to a level that can be
accomodated by the system's resources.
Examples of ngcc being able to recover after a worker process crashed:
- While idling: https://circleci.com/gh/angular/angular/682197
- While compiling: https://circleci.com/gh/angular/angular/682209

Previously, ngcc would run in parallel mode (using the
`ClusterExecutor`) when there were at least 2 CPU cores (and all other
requirements where met). On systems with just 2 CPU cores, this meant

reserved for the master process). In these cases, the tasks would still
be processed serially (on the one worker process), but we would also pay
the overhead of communicating between the master and worker processes.

Currently, if changes are made to `compiler-cli/ngcc` and to other
compiler-related files, then only the `fw-ngcc` group is requested
for review. This is because the `not contains_any_globs` condition
will be false for `fw-compiler` and the group will never become active.
We fix this by removing the incorrect condition and filtering out ngcc
files before checking `contains_any_globs` in the primary fw-compiler
condition.
PR Close#36661
Currently, when verifying our pullapprove configuration, we don't
respect modifications to the set of files in a condition.
e.g. It's not possible to do the following:
```
contains_any_globs(files.exclude(...), [
```
This prevents us from having codeowner groups which match a directory,
but want to filter out specific sub directories. For example, `fw-core`
matches all files in the core package. We want to exclude the schematics
from that glob. Usually we do this by another exclude condition.
This has a *significant* downside though. It means that fw-core will not
be requested if a PR changes schematic code, _and_ actual fw-core code.
To support these conditions, the pullapprove verification tool is
refactored, so that it no longer uses Regular expressions for parsing,
but rather evaluates the code through a dynamic function. This is
possible since the conditions are written in simple Python that can
be run in NodeJS too (with small modifications/transformations).

The cached file-system was implemented to speed up ngcc
processing, but in reality most files are not accessed many times
and there is no noticeable degradation in speed by removing it.
Benchmarking `ngcc -l debug` for AIO on a local machine
gave a range of 196-236 seconds with the cache and 197-224
seconds without the cache.
Moreover, when running in parallel mode, ngcc has a separate
file cache for each process. This results in excess memory usage.
Notably the master process, which only does analysis of entry-points
holds on to up to 500Mb for AIO when using the cache compared to
only around 30Mb when not using the cache.
Finally, the file-system cache being incorrectly primed with file
contents before being processed has been the cause of a number
of bugs. For example https://github.com/angular/angular-cli/issues/16860#issuecomment-614694269.

In the past, server-side rendered apps needed to convert URLs used in
API requests to absolute when rendering on the server. Originally, this
was handled in the `universal` guide and corresponding example app by
modifying the `HeroService` to use `APP_BASE_HREF` to derive the
absolute URL.
In #28956, the guide was updated to show an improved method: Specifying
an `HttpInterceptor` that took care of converting the URLs to absolute.
That interceptor was only provided when rendering the app on the server.
By mistake, the corresponding example app was not updated along with the
guide.
Since `@nguniversal/*` v7.1.0, it is no longer necessary to convert the
URLs to absolute inside the app. This is handled in the `@nguniversal`
libs (see angular/universal#897).
This commit updates the example app to remove unnecessary code and
modifies the guide to mention the issue with absolute URLs, but explain
that developers only need to worry about it when not using one of the
`@nguniversal/*-engine` packages.

The current ngcc lock-file strategy spawns a new process in order to
capture a potential `SIGINT` and remove the lock-file. For more
information see #35861.
Previously, this unlocker process was spawned as soon as the `LockFile`
was instantiated in order to have it available as soon as possible
(given that spawning a process is an asynchronous operation). Since the
`LockFile` was instantiated and passed to the `Executor`, this meant
that an unlocker process was spawned for each cluster worker, when
running ngcc in parallel mode. These processes were not needed, since
the `LockFile` was not used in cluster workers, but we still had to pay
the overhead of each process' own memory and V8 instance.
(NOTE: This overhead was small compared to the memory consumed by ngcc's
normal operations, but still unnecessary.)
This commit avoids the extra processes by only spawning an unlocker
process when running on the cluster master process and not on worker
processes.

Previously, when we needed to detect whether a file is external to a
package, we only checked whether the relative path to the file from the
package's root started with `..`. This would detect external imports
when the packages were siblings (e.g. peer dependencies or hoisted to
the top of `node_modules/` by the package manager), but would fail to
detect imports from packages located in nested `node_modules/` as
external. For example, importing `node_modules/foo/node_modules/bar`
from a file in `node_modules/foo/` would be considered internal to the
`foo` package.
This could result in processing/analyzing more files than necessary.
More importantly it could lead to errors due to trying to analyze
non-Angular packages that were direct dependencies of Angular packages.
This commit fixes it by also verifying that the relative path to a file
does not start with `node_modules/`.

PR Close#36486
When the compiler needs to convert a type reference to a value
expression, it may encounter a type that refers to a namespaced symbol.
Such namespaces need to be handled specially as there's various forms
available. Consider a namespace named "ns":
1. One can refer to a namespace by itself: `ns`. A namespace is only
allowed to be used in a type position if it has been merged with a
class, but even if this is the case it may not be possible to convert
that type into a value expression depending on the import form. More
on this later (case a below)
2. One can refer to a type within the namespace: `ns.Foo`. An import
needs to be generated to `ns`, from which the `Foo` property can then
be read.
3. One can refer to a type in a nested namespace within `ns`:
`ns.Foo.Bar` and possibly even deeper nested. The value
representation is similar to case 2, but includes additional property
accesses.
The exact strategy of how to deal with these cases depends on the type
of import used. There's two flavors available:
a. A namespaced import like `import * as ns from 'ns';` that creates
a local namespace that is irrelevant to the import that needs to be
generated (as said import would be used instead of the original
import).
If the local namespace "ns" itself is referred to in a type position,
it is invalid to convert it into a value expression. Some JavaScript
libraries publish a value as default export using `export = MyClass;`
syntax, however it is illegal to refer to that value using "ns".
Consequently, such usage in a type position *must* be accompanied by
an `@Inject` decorator to provide an explicit token.
b. An explicit namespace declaration within a module, that can be
imported using a named import like `import {ns} from 'ns';` where the
"ns" module declares a namespace using `declare namespace ns {}`.
In this case, it's the namespace itself that needs to be imported,
after which any qualified references into the namespace are converted
into property accesses.
Before this change, support for namespaces in the type-to-value
conversion was limited and only worked correctly for a single qualified
name using a namespace import (case 2a). All other cases were either
producing incorrect code or would crash the compiler (case 1a).
Crashing the compiler is not desirable as it does not indicate where
the issue is. Moreover, the result of a type-to-value conversion is
irrelevant when an explicit injection token is provided using `@Inject`,
so referring to a namespace in a type position (case 1) could still be
valid.
This commit introduces logic to the type-to-value conversion to be able
to properly deal with all type references to namespaced symbols.

Although this code has been part of Angular 9.x I only noticed this
error when upgrading to Angular 9.1.x because historically the source
locale data was not injected when localizing, but as of
angular/angular-cli#16394 (9.1.0) it is now included. This tipped me off
that my other bundles were not being built properly, and this change
allows me to build a valid ES5 bundle (I have also added a verification
step to my build pipeline to alert me if this error appears again in any
of my bundles).
I found the `locales/global/*.js` file paths being referenced by the

@angular-devkit/build-angular/src/utils/i18n-options.ts,
and following that it looks like it is actually loaded and used in
@angular-devkit/build-angular/src/utils/process-bundle.ts. I saw the
function `terserMangle` does appear that it is likely aware of the build
being ES5, but I'm not sure why this is not producing a valid ES5
bundle.
This change updates `tools/gulp-tasks/cldr/extract.js` to produce ES5
compliant `locales/global/*.js` and that fixes my issue. However, I am
not sure if @angular-devkit/build-angular should be modified to produce
a valid ES5 bundle instead or if the files could be TypeScript rather
than JavaScript files.
A test that a valid ES5 bundle is produced would be helpful, and I hope
this is reproducible and not some issue with my config.

Previously, the `pre-commit-validate` command (used in the `commit-msg`

We cannot use the environment variable directly in the `commit-msg` hook

the name of the environment variable and the validation script reads the

Currently the golden output of the circular-deps tool is purely
based on the order of source files passed to the tool, and on the
amount of imports inside source files.
This is actually resulting in deterministic output as running
the tool multiple times without any changes to source files,
results in the same output.
Though it seems like the tool is too strict and we can avoid
unnecessary golden changes if:
1. A source file that is part of a cycle is imported earlier (in terms
of how the analyzer visits them). This could result in the cycle path
starting with a different source file.
2. Source files which are not part of a cycle are imported earlier
(in terms of how the analyzer visits them). This could result in moved
items in the golden if re-approved (even though the cycles remain the same)
To fix this, we normalize the cycle path array that serves as
serializable data structure for the text-based goldens. Since
the paths represents a cycle, the path can be shifted in a
deterministic way so that cycles don't change unnecessarily
in the golden, and to simplify comparison of cycles.
Additionally, we sort the cycles in a deterministic way so

During static evaluation of expressions, the partial evaluator

Currently destroy hooks are stored in memory as `[1, hook, 5, hook]` where
the numbers represent the index at which to find the context and `hook` is
the function to be invoked. This breaks down for `multi` providers,
because the value at the index will be an array of providers, resulting in
the hook being invoked with an array of all the multi provider values,
rather than the provider that was destroyed. In ViewEngine `ngOnDestroy`
wasn't being called for `multi` providers at all.
These changes fix the issue by changing the structure of the destroy hooks to `[1, hook, 5, [0, hook, 3, hook]]` where the indexes inside the inner array point to the provider inside of the multi provider array. Note that this is slightly different from the original design which called for the structure to be `[1, hook, 5, [hook, hook]`, because in the process of implementing it, I realized that we wouldn't get passing the correct context if only some of the `multi` providers have `ngOnDestroy` and others don't.
I've run the newly-added `view_destroy_hooks` benchmark against these changes and compared it to master. The difference seems to be insignificant (between 1% and 2% slower).

When TypeScript downlevels ES2015+ code to ES5, it uses some helper
functions to emulate some ES2015+ features, such as spread syntax. The
TypeScript compiler can be configured to emit these helpers into the
transpiled code (which is controlled by the `noEmitHelpers` option -
false by default). It can also be configured to import these helpers
from the `tslib` module (which is controlled by the `importHelpers`
option - false by default).
While most of the time the helpers will be either emitted or imported,
it is possible that one configures their app to neither emit nor import
them. In that case, the helpers could, for example, be made available on
the global object. This is what `@nativescript/angular`
v9.0.0-next-2019-11-12-155500-01 does. See, for example, [common.js][1].
Ngcc must be able to detect and statically evaluate these helpers.
Previously, it was only able to detect emitted or imported helpers.
This commit adds support for detecting these helpers if they are neither
emitted nor imported. It does this by checking identifiers for which no
declaration (either concrete or inline) can be found against a list of
known TypeScript helper function names.

Each docs example has an `example-config.json` configuration file. Among
other things, this file can be used to specify what commands to run in
order to test the example. (If not specified, the `run-example-e2e.js`
script will run a default `yarn e2e` command.)
Previously, the property specifying the test commands was called `e2e`.
This is because in the past only e2e tests were run for docs examples.
Since recently, some examples may specify commands for other types of
tests (such as unit tests). Therefore, calling the property that holds
the list of test commands `e2e` no longer makes sense and can be
misleading to people looking at the configuration files.
This commit renamed the property to the more generic `tests`. In the
future, the `run-example-e2e.js` script (and corresponding npm script)
should be renamed and refactored to also avoid giving the impression
that only e2e tests are run.

In rare cases a project with configured `rootDirs` that has imports to
non-existent identifiers could fail in the migration.
This happens because based on the application code, the migration could
end up trying to resolve the `ts.Symbol` of such non-existent
identifiers. This isn't a problem usually, but due to a upstream bug
in the TypeScript compiler, a runtime error is thrown.
This is because TypeScript is unable to compute a relative path from the
originating source file to the imported source file which _should_
provide the non-existent identifier. An issue for this has been reported
upstream: https://github.com/microsoft/TypeScript/issues/37731. The
issue only surfaces since our migrations don't provide an absolute base
path that is used for resolving the root directories.
To fix this, we ensure that we never use relative paths when parsing
tsconfig files. More details can be found in the TS issue.

The `NgccReflectionHost`s have logic for detecting certain known
declarations (such as `Object.assign()` and TypeScript helpers), which
allows the `PartialEvaluator` to evaluate expressions it would not be
able to statically evaluate otherwise.
In #36089, `DelegatingReflectionHost` was introduced, which delegates to
a TypeScript `ReflectionHost` when reflecting on TypeScript files, which
for ngcc's case means `.d.ts` files of dependencies. As a result, ngcc
lost the ability to detect TypeScript helpers imported from `tslib`,
because `DelegatingReflectionHost` was not able to apply the known
declaration detection logic while reflecting on `tslib`'s `.d.ts` files.
This commit fixes this by ensuring `DelegatingReflectionHost` calls the
`NgccReflectionHost`'s `detectKnownDeclaration()` method as necessary,
even when using the TypeScript `ReflectionHost`.
NOTE:
The previous commit exposed a bug in ngcc that was hidden due to the
tests' being inconsistent with how the `ReflectionHost`s are used in the
actual program. The changes in this commit are verified by ensuring the
failing tests are now passing (hence no new tests are added).
PR Close#36284
In #36089, `DelegatingReflectionHost` was introduced. Under the hood, it
delegates another `NgccReflectionHost` in order to reflect over the
program's source files, while using a different TypeScript
`ReflectionHost` to reflect over `.d.ts` files (which is how external
dependencies are represented in the program).
Previously, the `NgccReflectionHost`s were used directly in tests. This
does not exercise them in the way they are exercised in the actual
program, because (when used directly) they will also reflect on `.d.ts`
files too (instead of delegating to the TypeScript `ReflectionHost`).
This could hide bugs that would happen on the actual program.
This commit fixes this by using the `DelegatingReflectionHost` in the
various `NgccReflectionHost` tests.
NOTE:
This change will cause some of the existing tests to start failing.

PR Close#35339
The `undecorated-classes-with-decorated-fields` migration has been
introduced with 904a2018e0, but misses
logic for decorating derived classes of undecorated classes which use
Angular features. Example scenario:
```ts
export abstract class MyBaseClass {
@Input() someInput = true;
}
export abstract class BaseClassTwo extends MyBaseClass {}
@Component(...)
export class MyButton extends BaseClassTwo {}
```
Both abstract classes would need to be migrated. Previously, the migration
only added `@Directive()` to `MyBaseClass`, but with this change, it
also decorates `BaseClassTwo`.
This is necessary because the Angular Compiler requires `BaseClassTwo` to
have a directive definition when it flattens the directive metadata for
`MyButton` in order to perform type checking. Technically, not decorating
`BaseClassTwo` does not break at runtime.
We basically want to enforce consistent use of `@Directive` to simplify the
mental model. [See the migration guide](https://angular.io/guide/migration-undecorated-classes#migrating-classes-that-use-field-decorators).

In Ivy, Angular decorators are compiled into static fields that are
inserted into a class declaration in a TypeScript transform. When
targeting Closure compiler such fields need to be annotated with
`@nocollapse` to prevent them from being lifted from a static field into
a variable, as that would prevent the Ivy runtime from being able to
find the compiled definitions.
Previously, there was a bug in TypeScript where synthetic comments added
in a transform would not be emitted at all, so as a workaround a global
regex-replace was done in the emit's `writeFile` callback that would add
the `@nocollapse` annotation to all static Ivy definition fields. This
approach is no longer possible when ngtsc is running as TypeScript
plugin, as a plugin cannot control emit behavior.
The workaround is no longer necessary, as synthetic comments are now
properly emitted, likely as of
https://github.com/microsoft/TypeScript/pull/22141 which has been

Ngcc supports providing a project-level configuration to affect how
certain dependencies are processed and also has a built-in fallback
configuration for some unmaintained packages. Each entry in these
configurations could be scoped to specific versions of a package by
providing a version range. If no version range is provided for a
package, it defaults to `*` (with the intention of matching any
version).
Previously, the installed version of a package was tested against the
version range using the [semver][1] package's `satisfies()` function
with the default options. By default, `satisfies()` does not match
pre-releases (see [here][2] for more details on reasoning). While this
makes sense when determining what version of a dependency to install
(trying to avoid unexpected breaking changes), it is not desired in the
case of ngcc.
This commit fixes it by explicitly specifying that pre-release versions
should be matched normally.

If ngcc is asked to target `lib2`, the `targetPath` will be
`project/node_modules/lib1/node_modules/lib2`.
Since `lib2` depends upon `lib3/entry-point`, ngcc will need to compute
the package path for `project/node_modules/lib3/entry-point`.
Since `project/node_modules/lib3/entry-point` is not contained in the `basePath`
`project/packages/app/node_modules`, ngcc failed to compute the `packagePath`
correctly, instead assuming that it was the same as the entry-point path.
Now we also consider the nearest `node_modules` folder to the entry-point
path as an additional `basePath`. If one is found then we use the first
directory directly below that `node_modules` directory as the package path.
In the case of our example this extra `basePath` would be `project/node_modules`
which allows us to compute the `packagePath` of `project/node_modules/lib3`.

Currently the `ts-circular-deps` tool uses a hard-coded module resolver
that only works in the `angular/angular` repository.
If the tool is consumed in other repositories through the shared
dev-infra package, the module resolution won't work, and a few
resolvable imports (usually cross-entry-points) are accidentally
skipped. For each test, the resolution might differ, so tests can
now configure their module resolution in a configuration file.
Note that we intentionally don't rely on tsconfig's for module
resolution as parsing their mappings rather complicates the
circular dependency tool. Additionally, not every test has a
corresponding tsconfig file.
Also, hard-coding mappings to `@angular/*` while accepting a
path to the packages folder would work, but it would mean
that the circular deps tool is no longer self-contained. Rather,
and also for better flexibility, a custom resolver should be
specified.

In #35381, a new Protractor config file was introduced in docs examples,
`protractor-puppeteer.conf.js`, that was only supposed to be used on CI

The logic to ignore the `protractor-puppeteer.conf.js` file was
incorrect, resulting in the file being retained in some examples (e.g.
[universal][1]). The problem was not immediately obvious, because most
examples explicitly specify all `**/*.js` files as ignored, but for

This commit augments the `FactoryDef` declaration of Angular decorated
classes to contain information about the parameter decorators used in
the constructor. If no constructor is present, or none of the parameters
have any Angular decorators, then this will be represented using the
`null` type. Otherwise, a tuple type is used where the entry at index `i`
corresponds with parameter `i`. Each tuple entry can be one of two types:
1. If the associated parameter does not have any Angular decorators,
the tuple entry will be the `null` type.
2. Otherwise, a type literal is used that may declare at least one of
the following properties:
- "attribute": if `@Attribute` is present. The injected attribute's
name is used as string literal type, or the `unknown` type if the
attribute name is not a string literal.
- "self": if `@Self` is present, always of type `true`.
- "skipSelf": if `@SkipSelf` is present, always of type `true`.
- "host": if `@Host` is present, always of type `true`.
- "optional": if `@Optional` is present, always of type `true`.
A property is only present if the corresponding decorator is used.
Note that the `@Inject` decorator is currently not included, as it's
non-trivial to properly convert the token's value expression to a
type that is valid in a declaration file.
Additionally, the `ComponentDefWithMeta` declaration that is created for
Angular components has been extended to include all selectors on
`ng-content` elements within the component's template.
This additional metadata is useful for tooling such as the Angular
Language Service, as it provides the ability to offer suggestions for
directives/components defined in libraries. At the moment, such
tooling extracts the necessary information from the _metadata.json_
manifest file as generated by ngc, however this metadata representation
is being replaced by the information emitted into the declaration files.

When two entry-points overlap, ngcc may attempt to process some

error preventing any other entry-points from being processed.
This commit changes ngcc so that if `errorOnFailedEntryPoint` is false, it will

Previously, when an entry-point contained code that caused its compilation

This change adds a new `errorOnFailedEntryPoint` option to `mainNgcc` that
specifies whether ngcc should exit immediately or log an error and continue
processing other entry-points.
The default is `false` so that ngcc will not error but continue processing
as much as possible. This is useful in post-install hooks, and async CLI
integration, where we do not have as much control over which entry-points
should be processed.
The option is forced to true if the `targetEntryPointPath` is provided,
such as the sync integration with the CLI, since in that case it is targeting
an entry-point that will actually be used in the current project so we do want
ngcc to exit with an error at that point.

Later when we implement the ability to continue processing when tasks have
failed to compile, we will also need to avoid processing tasks that depend
upon the failed task.
This refactoring exposes this list of dependent tasks in a way that can be
used to skip processing of tasks that depend upon a failed task.
It also changes the blocking model of the parallel mode of operation so
that non-typings tasks are now blocked on their corresponding typings task.
Previously the non-typings tasks could be triggered to run in parallel to
the typings task, since they do not have a hard dependency on each other,
but this made it difficult to skip task correctly if the typings task failed,
since it was possible that a non-typings task was already in flight when
the typings task failed. The result of this is a small potential degradation
of performance in async parallel processing mode, in the rare cases that
there were not enough unblocked tasks to make use of all the available

When ngcc is compiling an entry-point, it uses a `ReflectionHost` that
is specific to its format, e.g. ES2015, ES5, UMD or CommonJS. During the
compilation of that entry-point however, the reflector may be used to
reflect into external libraries using their declaration files.
Up until now this was achieved by letting all `ReflectionHost` classes
consider their parent class for reflector queries, thereby ending up in
the `TypeScriptReflectionHost` that is a common base class for all
reflector hosts. This approach has proven to be prone to bugs, as
failing to call into the base class would cause incompatibilities with
reading from declaration files.
The observation can be made that there's only two distinct kinds of
reflection host queries:
1. the reflector query is about code that is part of the entry-point
that is being compiled, or
2. the reflector query is for an external library that the entry-point
depends on, in which case the information is reflected
from the declaration files.
The `ReflectionHost` that was chosen for the entry-point should serve
only reflector queries for the first case, whereas a regular
`TypeScriptReflectionHost` should be used for the second case. This
avoids the problem where a format-specific `ReflectionHost` fails to
handle the second case correctly, as it isn't even considered for such
reflector queries.
This commit introduces a `ReflectionHost` that delegates to the
`TypeScriptReflectionHost` for AST nodes within declaration files,
otherwise delegating to the format-specific `ReflectionHost`.

Currently, when Angular code is built with Bazel and with Ivy, generated
factory shims (.ngfactory files) are not processed via the majority of
tsickle's transforms. This is a subtle effect of the build infrastructure,
but it boils down to a TsickleHost method `shouldSkipTsickleProcessing`.
For ngc_wrapped builds (Bazel + Angular), this method is defined in the
`@bazel/typescript` (aka bazel rules_typescript) implementation of
`CompilerHost`. The default behavior is to skip tsickle processing for files
which are not present in the original `srcs[]` of the build rule. In
Angular's case, this includes all generated shim files.
For View Engine factories this is probably desirable as they're quite
complex and they've never been tested with tsickle. Ivy factories however
are smaller and very straightforward, and it makes sense to treat them like
any other output.
This commit adjusts two independent implementations of
`shouldSkipTsickleProcessing` to enable transformation of Ivy shims:
* in `@angular/bazel` aka ngc_wrapped, the upstream `@bazel/typescript`
`CompilerHost` is patched to treat .ngfactory files the same as their
original source file, with respect to tsickle processing.
It is currently not possible to test this change as we don't have any test
that inspects tsickle output with bazel. It will be extensively tested in
g3.
* in `ngc`, Angular's own implementation is adjusted to allow for the
processing of shims when compiling with Ivy. This enables a unit test to
be written to validate the correct behavior of tsickle when given a host
that's appropriately configured to process factory shims.
For ngtsc-as-a-plugin, a similar fix will need to be submitted upstream in
tsc_wrapped.

Prior to this commit, Ivy compiler didn't handle directive inputs with interpolations located on `<ng-template>` elements (e.g. `<ng-template dir="{{ field }}">`). That was the case for regular inputs as well as inputs that should be processed via i18n subsystem (e.g. `<ng-template i18n-dir dir="Hello {{ name }}">`). This commit adds support for such expressions for explicit `<ng-template>`s as well as a number of tests to confirm the behavior.

By default, `zone.js` wrap uncaught promise error and wrap it to a new Error object with some
additional information includes the value of the error and the stack trace.
Consider the following example:
```
Zone.current
.fork({
name: 'promise-error',
onHandleError: (delegate: ZoneDelegate, current: Zone, target: Zone, error: any): boolean => {
console.log('caught an error', error);
delegate.handleError(target, error);
return false;
}
}).run(() => {
const originalError = new Error('testError');
Promise.reject(originalError);
});
```
The `promise-error` zone catches a wrapped `Error` object whose `rejection` property equals
to the original error, and the message will be `Uncaught (in promise): testError....`,
You can disable this wrapping behavior by defining a global configuraiton
`__zone_symbol__DISABLE_WRAPPING_UNCAUGHT_PROMISE_REJECTION = true;` before importing `zone.js`.

Prior to this commit, i18n runtime logic relied on the assumption that provided translation is syntactically correct, specifically around ICU syntax. However provided translations might contain some errors that lead to parsing failure. Specifically when translation contains curly braces, runtime i18n logic tries to parse them as an ICU expression and fails. This commit validates ICU parsing result (making sure it was parsed correctly) and throws an error if parsing error happens. The error that is thrown also contains translated message text for easier debugging.
Note: the check and the error message introduced in this PR is a safeguard against the problem that led to unhandled i18n runtime logic crash. So the framework behavior remains the same, we just improve the error message and it should be safe to merge to the patch branch.

This commit adds support in the Angular monorepo and in the Angular
compiler(s) for TypeScript 3.8. All packages can now compile with
TS 3.8.
For most of the repo, only a handful few typings adjustments were needed:
* TS 3.8 has a new `CustomElementConstructor` DOM type, which enforces a
zero-argument constructor. The `NgElementConstructor` type previously
declared a required `injector` argument despite the fact that its
implementation allowed `injector` to be optional. The interface type was
updated to reflect the optionality of the argument.
* Certain error messages were changed, and expectations in tests were
updated as a result.
* tsserver (part of language server) now returns performance information in
responses, so test expectations were changed to only assert on the actual
body content of responses.
For compiler-cli and schematics (which use the TypeScript AST) a major
breaking change was the introduction of the export form:
```typescript
export * as foo from 'bar';
```
This is a `ts.NamespaceExport`, and the `exportClause` of a
`ts.ExportDeclaration` can now take this type as well as `ts.NamedExports`.
This broke a lot of places where `exportClause` was assumed to be
`ts.NamedExports`.
For the most part these breakages were in cases where it is not necessary
to handle the new `ts.NamedExports` anyway. ngtsc's design uses the
`ts.TypeChecker` APIs to understand syntax and so automatically supports the
new form of exports.
The View Engine compiler on the other hand extracts TS structures into
metadata.json files, and that format was not designed for namespaced
exports. As a result it will take a nontrivial amount of work if we want to
support such exports in View Engine. For now, these new exports are not
accounted for in metadata.json, and so using them in "folded" Angular
expressions will result in errors (probably claiming that the referenced
exported namespace doesn't exist).
Care was taken to only use TS APIs which are present in 3.7/3.6, as Angular
needs to remain compatible with these for the time being.

Prior to this commit, while calculating the scope for a module, Ivy compiler processed `declarations` field first and `imports` after that. That results in a couple issues:
* for Pipes with the same `name` and present in `declarations` and in an imported module, Pipe from imported module was selected. In View Engine the logic is opposite: Pipes from `declarations` field receive higher priority.
* for Directives with the same selector and present in `declarations` and in an imported module, we first invoked the logic of a Directive from `declarations` field and after that - imported Directive logic. In View Engine, it was the opposite and the logic of a Directive from the `declarations` field was invoked last.
In order to align Ivy and View Engine behavior, this commit updates the logic in which we populate module scope: we first process all imports and after that handle `declarations` field. As a result, in Ivy both use-cases listed above work similar to View Engine.

Currently, when Angular code is built with Bazel and with Ivy, generated
factory shims (.ngfactory files) are not processed via the majority of
tsickle's transforms. This is a subtle effect of the build infrastructure,
but it boils down to a TsickleHost method `shouldSkipTsickleProcessing`.
For ngc_wrapped builds (Bazel + Angular), this method is defined in the
`@bazel/typescript` (aka bazel rules_typescript) implementation of
`CompilerHost`. The default behavior is to skip tsickle processing for files
which are not present in the original `srcs[]` of the build rule. In
Angular's case, this includes all generated shim files.
For View Engine factories this is probably desirable as they're quite
complex and they've never been tested with tsickle. Ivy factories however
are smaller and very straightforward, and it makes sense to treat them like
any other output.
This commit adjusts two independent implementations of
`shouldSkipTsickleProcessing` to enable transformation of Ivy shims:
* in `@angular/bazel` aka ngc_wrapped, the upstream `@bazel/typescript`
`CompilerHost` is patched to treat .ngfactory files the same as their
original source file, with respect to tsickle processing.
It is currently not possible to test this change as we don't have any test
that inspects tsickle output with bazel. It will be extensively tested in
g3.
* in `ngc`, Angular's own implementation is adjusted to allow for the
processing of shims when compiling with Ivy. This enables a unit test to
be written to validate the correct behavior of tsickle when given a host
that's appropriately configured to process factory shims.
For ngtsc-as-a-plugin, a similar fix will need to be submitted upstream in
tsc_wrapped.

The options for `flatModuleId` and `flatModuleOutFile` had been removed in the CLI
from generated libraries with 718ee15b9a.
This has been done because `ng-packagr` (which is used to build the
libraries) automatically set these options in-memory when it compiles the library.
No migration has been created for this because there was no actual need to get rid of
this. Keeping the options in the library `tsconfig` does not cause any problems unless
the `tsconfig` is used outside of `ng-packagr`. This was not anticipated, but is now
commonly done in `ng update` migrations.
The `ng update` migrations try to create an instance of the `AngularCompilerProgram` by
simply parsing the `tsconfig`. The migrations make the valid assumption that `tsconfig` files
are not incomplete/invalid. They _definitely_ are in the file system though. It just works for
libraries because `ng-packagr` in-memory completes the invalid `tsconfig` files, so that they
can be passed to the `@angular/compiler-cli`.
We can't have this logic in the `ng update` migrations because it's
out-of-scope for individual migrations to distinguish between libraries
and applications. Also it would be out-of-scope to parse the
`ng-packagr` configuration and handle the tsconfig in-memory completion.
As a workaround though, we can remove the flat-module bundle options
in-memory when creating the compiler program. This is acceptable since
we don't emit the program and the flat module bundles are not needed.

Previously, `NgPackagesInstaller` would only look for Angular local
packages and do so by listing all (deeply nested) files in
`dist/packages-dist/` and looking for `package.json` files nested two
levels deep (i.e. `dist/packages-dist/*/package.json`). Thus, it would
unnecessarily check a large number of files.
This commit changes the package detection logic to instead look for
a `package.json` file directly inside each subdirectory of
`dist/packages-dist/`, which speeds up the operation.
It also refactors the code to make it easier to look for packages in
other directories (besides `dist/packages-dist/`). This will be useful
in a subsequent commit to look for and use the locally built `zone.js`
package (from `dist/zone.js-dist/`).

This is a follow up to #35637 which resolved a similar issue for `ComponentFactoryResolver`, but not the root cause. When a `NgModuleRef` is created, it instantiates an `Injector` internally which in turn resolves all of injector types.

This commit performs a modularization of the Language Service's existing
diagnostic messages. Such a modularization has two primary advantages:
- Centralization and decoupling of error messages from the code that
generates them makes it easy to add/delete/edit diagnostic messages,
and allows for independent iteration of diagnostic messages and
diagnostic generation.
- Prepares for additional features like annotating the locations where a
diagnostic is generated and enabling the configuration of which
diagnostics should be reported by the language service.
Although it would be preferable to place the diagnostics registry in an
independent JSON file, for ease of typing diagnostic types as an enum
variant of 'ts.DiagnosticCategory', the registry is stored as an object.

an UMD module export called `ng.cdk.a11Y`.

When the `NgIf` directive is used in a template, its context variables
can be used to capture the bound value. This is typically used together
with a pipe or function call, where the resulting value is captured in a
context variable. There's two syntax forms available:
1. Binding to `NgIfContext.ngIf` using the `as` syntax:
```html
<span *ngIf="(user$ | async) as user">{{user.name}}</span>
```
2. Binding to `NgIfContext.$implicit` using the `let` syntax:
```html
<span *ngIf="user$ | async; let user">{{user.name}}</span>
```
Because of the semantics of `ngIf`, it is known that the captured
context variable is non-nullable, however the template type checker
would not consider them as such and still report errors when
`strictNullTypes` is enabled.
This commit updates `NgIf`'s context guard to make the types of the
context variables non-nullable, avoiding the issue.

from `packages/compiler/src/expression_parser/ast.ts` because they
contain duplicate and buggy implementation, and their use cases could be
sufficiently covered by `RecursiveAstVisitor` if the latter implements the
`visit` method. This use case is only needed in the language service.
With this change, any visitor that extends `RecursiveAstVisitor` could
just define their own `visit` function and the parent class will behave
correctly.
A bit of historical context:
In language service, we need a way to tranverse the expression AST in a
selective manner based on where the user's cursor is. This means we need a
"filtering" function to decide which node to visit and which node to not
visit. Instead of refactoring `RecursiveAstVisitor` to support this,
`visitAstChildren` was created. `visitAstChildren` duplicates the
implementation of `RecursiveAstVisitor`, but introduced some bugs along
the way. For example, in `visitKeyedWrite`, it visits
```
obj -> key -> obj
```
instead of
```
obj -> key -> value
```
Moreover, because of the following line
```
visitor.visit && visitor.visit(ast, context) || ast.visit(visitor, context);

`visitAstChildren` visits every node *twice*.

For view and content queries, the Ivy compiler attempts to statically
evaluate the predicate token so that string predicates containing
comma-separated reference names can be split into an array of strings
during compilation. When the predicate is a dynamic value that cannot be

produce an error. This behavior breaks a use-case where an `InjectionToken`

It's possible to pass a directive as an input to itself. Consider:
```html
<some-cmp #ref [value]="ref">
```
Since the template type-checker attempts to infer a type for `<some-cmp>`
using the values of its inputs, this creates a circular reference where the
type of the `value` input is used in its own inference:
```typescript
var _t0 = SomeCmp.ngTypeCtor({value: _t0});
```
Obviously, this doesn't work. To resolve this, the template type-checker
used to generate a `null!` expression when a reference would otherwise be
circular:
```typescript
var _t0 = SomeCmp.ngTypeCtor({value: null!});
```
This effectively asks TypeScript to infer a value for this context, and
works well to resolve this simple cycle. However, if the template
instead tries to use the circular value in a larger expression:
```html
<some-cmp #ref [value]="ref.prop">
```
The checker would generate:
```typescript
var _t0 = SomeCmp.ngTypeCtor({value: (null!).prop});
```
In this case, TypeScript can't figure out any way `null!` could have a
`prop` key, and so it infers `never` as the type. `(never).prop` is thus a
type error.
This commit implements a better fallback pattern for circular references to
directive types like this. Instead of generating a `null!` in place for the
reference, a type is inferred by calling the type constructor again with
`null!` as its input. This infers the widest possible type for the directive
which is then used to break the cycle:
```typescript
var _t0 = SomeCmp.ngTypeCtor(null!);
var _t1 = SomeCmp.ngTypeCtor({value: _t0.prop});
```
This has the desired effect of validating that `.prop` is legal for the
directive type (the type of `#ref`) while also avoiding a cycle.

Currently we resolve the `NgModuleRef.componentFactoryResolver` by going through the injector, but the problem is that `ComponentFactoryResolver` has a dependency on `NgModuleRef`, which means that if the module that's attached to the ref tries to inject `ComponentFactoryResolver` in its constructor, we'll create a circular dependency which throws at runtime.
These changes resolve the issue by creating the `ComponentFactoryResolver` manually ahead of time without going through the injector. We can do this safely, because the only dependency for the resolver is the current module ref which is providing it.
Aside from fixing the issue, another advantage to this approach is that it should reduce the amount of generated JS, because it removes a getter and a provider definitio.

Technically, function definitions can live anywhere because they are

function definitions are referred in another static object that is

```
which turns to the following in Closure's module system:
```
goog.module('m');
exports.obj = {f};
function f() {...}
exports.f = f;

var b = a; var a = function() {...}; // now b is undefined.

The perf issue comes from a "diamond" problem, where module X is overridden which imports modules A and B, which both import module C.

Under View Engine's default (non-fullTemplateTypeCheck) checking, object and
array literals which appear in templates are treated as having type `any`.
This allows a number of patterns which would not otherwise compile, such as
indexing an object literal by a string:
```html
{{ {'a': 1, 'b': 2}[value] }}
```
(where `value` is `string`)
Ivy, meanwhile, has always inferred strong types for object literals, even
in its compatibility mode. This commit fixes the bug, and adds the
`strictLiteralTypes` flag to specifically control this inference. When the
flag is `false` (in compatibility mode), object and array literals receive
the `any` type.
PR Close#35462
In its default compatibility mode, the Ivy template type-checker attempts to
emulate the View Engine default mode as accurately as is possible. This
commit addresses a gap in this compatibility that stems from a View Engine
type-checking bug.
Consider two template expressions:
```html
{{ obj?.field }}
{{ fn()?.field }}
```
and suppose that the type of `obj` and `fn()` are the same - both return
either `null` or an object with a `field` property.
Under View Engine, these type-check differently. The `obj` case will catch
if the object type (when not null) does not have a `field` property, while
the `fn()` case will not. This is due to how View Engine represents safe
navigations:
```typescript
// for the 'obj' case
(obj == null ? null as any : obj.field)
// for the 'fn()' case
let tmp: any;
((tmp = fn()) == null ? null as any : tmp.field)
```
Because View Engine uses the same code generation backend as it does to
produce the runtime code for this expression, it uses a ternary for safe
navigation, with a temporary variable to avoid invoking 'fn()' twice. The
type of this temporary variable is 'any', however, which causes the
`tmp.field` check to be meaningless.
Previously, the Ivy template type-checker in compatibility mode assumed that
`fn()?.field` would always check for the presence of 'field' on the non-null
result of `fn()`. This commit emulates the View Engine bug in Ivy's
compatibility mode, so an 'any' type will be inferred under the same
conditions.
As part of this fix, a new format for safe navigation operations in template
type-checking code is introduced. This is based on the realization that
ternary based narrowing is unnecessary.
For the `fn()` case in strict mode, Ivy now generates:
```typescript
(null as any ? fn()!.field : undefined)
```
This effectively uses the ternary operator as a type "or" operation. The
resulting type will be a union of the type of `fn()!.field` with
`undefined`.
For the `fn()` case in compatibility mode, Ivy now emulates the bug with:
```typescript
(fn() as any).field
```
The cast expression includes the call to `fn()` and allows it to be checked
while still returning a type of `any` from the expression.
For the `obj` case in compatibility mode, Ivy now generates:
```typescript
(obj!.field as any)
```
This cast expression still returns `any` for its type, but will check for
the existence of `field` on the type of `obj!`.

In ES5 code, TypeScript requires certain helpers (such as
`__spreadArrays()`) to be able to support ES2015+ features. These
helpers can be either imported from `tslib` (by setting the
`importHelpers` TS compiler option to `true`) or emitted inline (by
setting the `importHelpers` and `noEmitHelpers` TS compiler options to
`false`, which is the default value for both).
Ngtsc's `StaticInterpreter` (which is also used during ngcc processing)
is able to statically evaluate some of these helpers (currently
`__assign()`, `__spread()` and `__spreadArrays()`), as long as
`ReflectionHost#getDefinitionOfFunction()` correctly detects the
declaration of the helper. For this to happen, the left-hand side of the
corresponding call expression (i.e. `__spread(...)` or
`tslib.__spread(...)`) must be evaluated as a function declaration for
`getDefinitionOfFunction()` to be called with.
In the case of imported helpers, the `tslib.__someHelper` expression was
resolved to a function declaration of the form
`export declare function __someHelper(...args: any[][]): any[];`, which
allows `getDefinitionOfFunction()` to correctly map it to a TS helper.
In contrast, in the case of emitted helpers (and regardless of the
module format: `CommonJS`, `ESNext`, `UMD`, etc.)), the `__someHelper`
identifier was resolved to a variable declaration of the form
`var __someHelper = (this && this.__someHelper) || function () { ... }`,
which upon further evaluation was categorized as a `DynamicValue`
(prohibiting further evaluation by the `getDefinitionOfFunction()`).
As a result of the above, emitted TypeScript helpers were not evaluated
in ES5 code.
---
This commit changes the detection of TS helpers to leverage the existing
`KnownFn` feature (previously only used for built-in functions).
`Esm5ReflectionHost` is changed to always return `KnownDeclaration`s for
TS helpers, both imported (`getExportsOfModule()`) as well as emitted
(`getDeclarationOfIdentifier()`).
Similar changes are made to `CommonJsReflectionHost` and
`UmdReflectionHost`.
The `KnownDeclaration`s are then mapped to `KnownFn`s in
`StaticInterpreter`, allowing it to statically evaluate call expressions
involving any kind of TS helpers.

When statically evaluating CommonJS code it is possible to find that we
are looking for the declaration of an identifier that actually came from
a typings file (rather than a CommonJS file).
Previously, the CommonJS reflection host would always try to use a
CommonJS specific algorithm for finding identifier declarations, but
when the id is actually in a typings file this resulted in the returned
declaration being the containing file of the declaration rather than the
declaration itself.
Now the CommonJS reflection host will check to see if the file
containing the identifier is a typings file and use the appropriate
stategy.
(Note: This is the equivalent of #34356 but for CommonJS.)

In #33705 we made it so that we generate pure functions for object/array literals in order to avoid having them be shared across elements/views. The problem this introduced is that further down the line the `ContantPool` uses the generated literal in order to figure out whether to share an existing factory or to create a new one. `ConstantPool` determines whether to share a factory by creating a key from the AST node and using it to look it up in the factory cache, however the key generation function didn't handle function invocations and replaced them with `null`. This means that the key for `{foo: pureFunction0(...)}` and `{foo: null}` are the same.
These changes rework the logic so that instead of generating a `null` key
for function invocations, we generate a variable called `<unknown>` which
shouldn't be able to collide with anything.

It's unclear why that happens, but a reasonable theory would be that
the TS compilation accidentally picked up the types from `chokidar`

To achieve this, a second Protractor configuration is created (which is
ignored when creating the ZIP archives) that extends the original one
and passes the approperiate arguments to use the browser provided by

webdriver-manager update --gecko=false --standalone=false $CI_CHROMEDRIVER_VERSION_ARG is now replaced with node webdriver-manager-update.js in the root package.json, which checks which version of chrome puppeteer has come bundled with & downloads informs webdriver-manager to download the corresponding chrome driver version.

"// resolutions": "Ensure a single version of webdriver-manager which comes from root node_modules that has already run webdriver-manager update",
"resolutions": {

This should speed up each integration postinstall by a few seconds.
Further, integration test package.json files link puppeteer via file:../../node_modules/puppeteer which is the ideal situation as the puppeteer post-install won't download chrome if it is already downloaded. In CI, since node_modules is cached it should not need to download Chrome either unless the node_modules cache is busted.
NB: each version of puppeteer comes bundles with a specific version of chrome. Root package.json & yarn.lock currently pull down puppeteer 2.1.0 which comes with chrome 80. See https://github.com/puppeteer/puppeteer#q-which-chromium-version-does-puppeteer-use for more info.

Note that with this change, users who legitimately make a typo in their

false positive is worse than false negative. However, if users follow
the suggestion, add ? or ! to their code, then the error will be surfaced.

In Ivy's template type checker, event bindings are checked in a closure
to allow for accurate type inference of the `$event` parameter. Because
of the closure, any narrowing effects of template guards will no longer
be in effect when checking the event binding, as TypeScript assumes that
the guard outside of the closure may no longer be true once the closure
is invoked. For more information on TypeScript's Control Flow Analysis,
please refer to https://github.com/microsoft/TypeScript/issues/9998.
In Angular templates, it is known that an event binding can only be
executed when the view it occurs in is currently rendered, hence the
corresponding template guard is known to hold during the invocation of
an event handler closure. As such, it is desirable that any narrowing
effects from template guards are still in effect within the event
handler closure.
This commit tweaks the generated Type-Check Block (TCB) to repeat all
template guards within an event handler closure. This achieves the
narrowing effect of the guards even within the closure.

The `TargetedEntryPointFinder` must work out what the
containing package is for each entry-point that it finds.
The logic for doing this was flawed in the case that the
package was in a path-mapped directory and not in a

were incorrectly setting their own path as the package
path, rather than the primary entry-point path.

In the past we had connecitivity issues on Saucelabs. Browsers on
mobile devices were not able to properly resolve the `localhost`
hostname through the tunnel. This is because the device resolves
`localhost` or `127.0.0.1` to the actual Saucelabs device, while it
should resolve to the tunnel host machine (in our case the CircleCI VM).
In the past, we simply disabled the failing devices and re-enabled the
devices later. At this point, the Saucelabs team claimed that the
connecitivy/proxy issues were fixed.
Saucelabs seems to have a process for VMs which ensures that requests to
`localhost` / `127.0.0.1` are properly resolved through the tunnel. This
process is not very reliable and can cause tests to fail. Related issues have been
observed/mentioned in the Saucelabs support docs. e.g.
https://support.saucelabs.com/hc/en-us/articles/115002212447-Unable-to-Reach-Application-on-localhost-for-Tests-Run-on-Safari-8-and-9-and-Edgehttps://support.saucelabs.com/hc/en-us/articles/225106887-Safari-and-Internet-Explorer-Won-t-Load-Website-When-Using-Sauce-Connect-on-Localhost
In order to ensure that requests are always resolved through the tunnel,
we add our own domain alias in the CircleCI's hosts file, and enforce that
it is always resolved through the tunnel (using the `--tunnel-domains` SC flag).
Saucelabs devices by default will never resolve this domain/hostname to the
actual local Saucelabs device.

This commit implements an experimental integration with tsc_wrapped, where
it can load the Angular compiler as a plugin and perform Angular
transpilation at a user's request.
This is an alternative to the current ngc_wrapped mechanism, which is a fork
of tsc_wrapped from several years ago. tsc_wrapped has improved
significantly since then, and this feature will allow Angular to benefit
from those improvements.
Currently the plugin API between tsc_wrapped and the Angular compiler is a
work in progress, so NgTscPlugin does not yet implement any interfaces from
@bazel/typescript (the home of tsc_wrapped). Instead, an interface is
defined locally to guide this standardization.

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

Sometimes, a request for definitions will return multiple of the same

- multiple template binding expressions in the same attribute
- something like "*ngFor="let i of items; trackBy: test" has two
template bindings, resulting in two template binding ASTs at the
same location (the attribute span). The language service then parses
both of these bindings individually, resulting in two independent
but identical definitions. For more context, see https://github.com/angular/angular/pull/34847#discussion_r371006680.

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)

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.

for (let i = parseStyle(text); i <= 0; i = parseStyleNext(text, i)) {
const key = getLastParsedKey();
const value = getLastParsedValue();
...
}
```
This change makes it easier to invoke the parser from other locations in the system without paying the cost of creating and iterating over `Map` of styles.
PR Closes#34418
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 change introduces class/style reconciliation algorithm for DOM elements.
NOTE: The code is not yet hooked up, it will be used by future style algorithm.
Background:
Styling algorithm currently has [two paths](https://hackmd.io/@5zDGNGArSxiHhgvxRGrg-g/rycZk3N5S)
when computing how the style should be rendered.
1. A direct path which concatenates styling and uses `elemnent.className`/`element.style.cssText` and
2. A merge path which uses internal data structures and uses `element.classList.add/remove`/`element.style[property]`.
The situation is confusing and hard to follow/maintain. So a future PR will remove the merge-path and do everything with
direct-path. This however breaks when some other code adds class or style to the element without Angular's knowledge.
If this happens instead of switching from direct-path to merge-path algorithm, this change provides a different mental model
whereby we always do `direct-path` but the code which writes to the DOM detects the situation and reconciles the out of bound write.
The reconciliation process is as follows:
1. Detect that no one has modified `className`/`cssText` and if so just write directly (fast path).
2. If out of bounds write did occur, switch from writing using `className`/`cssText` to `element.classList.add/remove`/`element.style[property]`.
This does require that the write function computes the difference between the previous Angular expected state and current Angular state.
(This requires a parser. The advantage of having a parser is that we can support `style="width: {{exp}}px" kind of bindings.`)
Compute the diff and apply it in non destructive way using `element.classList.add/remove`/`element.style[property]`
Properties of approach:
- If no out of bounds style modification:
- Very fast code path: Just concatenate string in right order and write them to DOM.
- Class list order is preserved
- If out of bounds style modification detected:
- Penalty for parsing
- Switch to non destructive modification: `element.classList.add/remove`/`element.style[property]`
- Switch to alphabetical way of setting classes.

Previously, NgtscProgram lived in the main @angular/compiler-cli package
alongside the legacy View Engine compiler. As a result, the main package
depended on all of the ngtsc internal packages, and a significant portion of
ngtsc logic lived in NgtscProgram.
This commit refactors NgtscProgram and moves the main logic of compilation
into a new 'core' package. The new package defines a new API which enables
implementers of TypeScript compilers (compilers built using the TS API) to
support Angular transpilation as well. It involves a new NgCompiler type
which takes a ts.Program and performs Angular analysis and transformations,
as well as an NgCompilerHost which wraps an input ts.CompilerHost and adds
any extra Angular files.
Together, these two classes are used to implement a new NgtscProgram which
adapts the legacy api.Program interface used by the View Engine compiler
onto operations on the new types. The new NgtscProgram implementation is
significantly smaller and easier to reason about.
The new NgCompilerHost replaces the previous GeneratedShimsHostWrapper which
lived in the 'shims' package.
A new 'resource' package is added to support the HostResourceLoader which
previously lived in the outer compiler package.
As a result of the refactoring, the dependencies of the outer
@angular/compiler-cli package on ngtsc internal packages are significantly
trimmed.
This refactoring was driven by the desire to build a plugin interface to the
compiler so that tsc_wrapped (another consumer of the TS compiler APIs) can
perform Angular transpilation on user request.

In #34288, ngtsc was refactored to separate the result of the analysis
and resolve phase for more granular incremental rebuilds. In this model,
any errors in one phase transition the trait into an error state, which
prevents it from being ran through subsequent phases. The ngcc compiler
on the other hand did not adopt this strict error model, which would
cause incomplete metadata—due to errors in earlier phases—to be offered
for compilation that could result in a hard crash.
This commit updates ngcc to take advantage of ngtsc's `TraitCompiler`,
that internally manages all Ivy classes that are part of the
compilation. This effectively replaces ngcc's own `AnalyzedFile` and
`AnalyzedClass` types, together with all of the logic to drive the
`DecoratorHandler`s. All of this is now handled in the `TraitCompiler`,
benefiting from its explicit state transitions of `Trait`s so that the
ngcc crash is a thing of the past.

Previously, while trying to build an `NgccReflectionHost`'s
`privateDtsDeclarationMap`, `computePrivateDtsDeclarationMap()` would
try to collect exported declarations from all source files of the
program (i.e. without checking whether they were within the target
package, as happens for declarations in `.d.ts` files).
Most of the time, that would not be a problem, because external packages
would be represented as `.d.ts` files in the program. But when an
external package had no typings, the JS files would be used instead. As
a result, the `ReflectionHost` would try to (unnecessarilly) parse the
file in order to extract exported declarations, which in turn would be
harmless in most cases.
There are certain cases, though, where the `ReflectionHost` would throw
an error, because it cannot parse the external package's JS file. This
could happen, for example, in `UmdReflectionHost`, which expects the
file to contain exactly one statement. See #34544 for more details on a
real-world failure.
This commit fixes the issue by ensuring that
`computePrivateDtsDeclarationMap()` will only collect exported
declarations from files within the target package.

This commit fixes a bug in the incremental rebuild engine of ngtsc, where if
a component was removed from its NgModule, it would not be properly
re-emitted.
The bug stemmed from the fact that whether to emit a file was a decision
based purely on the updated dependency graph, which captures the dependency
structure of the rebuild program. This graph has no edge from the component
to its former module (as it was removed, of course), so the compiler
erroneously decides not to emit the component.
The bug here is that the compiler does know, from the previous dependency
graph, that the component file has logically changed, since its previous
dependency (the module file) has changed. This information was not carried
forward into the set of files which need to be emitted, because it was
assumed that the updated dependency graph was a more accurate source of that
information.
With this commit, the set of files which need emit is pre-populated with the
set of logically changed files, to cover edge cases like this.

FileToModuleHost aliasing supports compilation within environments that have
two properties:
1. A `FileToModuleHost` exists which defines canonical module names for any
given TS file.
2. Dependency restrictions exist which prevent the import of arbitrary files
even if such files are within the .d.ts transitive closure of a
compilation ("strictdeps").
In such an environment, generated imports can only go through import paths
which are already present in the user program. The aliasing system supports
the generation and consumption of such imports at runtime.
`FileToModuleHost` aliasing does not emit re-exports in .d.ts files. This
means that it's safe to rely on alias re-exports in generated .js code (they
are guaranteed to exist at runtime) but not in template type-checking code
(since TS will not be able to follow such imports). Therefore, non-aliased
imports should be used in template type-checking code.
This commit adds a `NoAliasing` flag to `ImportFlags` and sets it when
generating imports in template type-checking code. The testing environment
is also patched to support resolution of FileToModuleHost canonical paths
within the template type-checking program, enabling testing of this change.

Previously, when generating template type-checking code, casts to 'any' were
produced as `expr as any`, regardless of the expression. However, for
certain expression types, this led to precedence issues with the cast. For
example, `a !== b` is a `ts.BinaryExpression`, and wrapping it directly in
the cast yields `a !== b as any`, which is semantically equivalent to
`a !== (b as any)`. This is obviously not what is intended.
Instead, this commit adds a list of expression types for which a "bare"
wrapping is permitted. For other expressions, parentheses are added to

It's possible to declare multiple inputs for a directive/component which all
map to the same property name. This is usually done in error, as only one of
any bindings to the property will "win".
In the template type-checker, an error was previously being raised as a
result of this ambiguity. Specifically, a type constructor was produced
which required a binding for each field, but only one of the fields had
a value via the binding. TypeScript would (rightfully) error on missing
values for the remaining fields. This ultimately was happening when the
code which generated the default values for "unset" inputs belonging to
directives or pipes used the final mapping from properties to fields as
a source for field names.
Instead, this commit uses the original list of fields to generate unset
input values, which correctly provides values for fields which shared a
property name but didn't receive the final binding.

Consider a library that uses a shared constant for host bindings. e.g.
```ts
export const BASE_BINDINGS= {
'[class.mat-themed]': '_isThemed',
}
----
@Directive({
host: {...BASE_BINDINGS, '(click)': '...'}
})
export class Dir1 {}
@Directive({
host: {...BASE_BINDINGS, '(click)': '...'}
})
export class Dir2 {}
```
Previously when these components were shipped as part of the
library to NPM, consumers were able to consume `Dir1` and `Dir2`.
No errors showed up.
Now with Ivy, when ngcc tries to process the library, an error
will be thrown. The error is stating that the host bindings should
be an object (which they obviously are). This happens because
TypeScript transforms the object spread to individual
`Object.assign` calls (for compatibility).
The partial evaluator used by the `@Directive` annotation handler
is unable to process this expression because there is no
integrated support for `Object.assign`. In View Engine, this was
not a problem because the `metadata.json` files from the library
were used to compute the host bindings.

Ngcc adds properties to the `package.json` files of the entry-points it
processes to mark them as processed for a format and point to the
created Ivy entry-points (in case of `--create-ivy-entry-points`). When
running ngcc in parallel mode (which is the default for the standalone
ngcc command), multiple formats can be processed simultaneously for the
same entry-point and the order of completion is not deterministic.
Previously, ngcc would append new properties at the end of the target
object in `package.json` as soon as the format processing was completed.
As a result, the order of properties in the resulting `package.json`
(when processing multiple formats for an entry-point in parallel) was
not deterministic. For tools that use file hashes for caching purposes
(such as Bazel), this lead to a high probability of cache misses.
This commit fixes the problem by ensuring that the position of
properties added to `package.json` files is deterministic and
independent of the order in which each format is processed.

When searching the typings program for a package for imports a
distinction is drawn between missing entry-points and deep imports.
Previously in the `DtsDependencyHost` these deep imports may be
marked as missing if there was no typings file at the deep import path.
Instead there may be a javascript file instead. In practice this means
the import is "deep" and not "missing".
Now the `DtsDependencyHost` will also consider `.js` files when checking
for deep-imports, and it will also look inside `@types/...` for a suitable
deep-imported typings file.

The compiler's `I18NHtmlParser` may expand template nodes that have
internationalization metadata attached to them; for instance,
```html

gets expanded to an AST with the i18n metadata extracted and text filled
in as necessary; to the language service, the template above, as read in
the AST, now looks something like
```html
<div>{{$implicit}}</div>
```
This is undesirable for the language service because we want to preserve
the original form of the source template source code, and have
information about the original values of the template. The language
service also does not need to use an i18n parser -- we don't generate
any template output.
To fix this turns out to be as easy as moving to using a raw
`HtmlParser`.

A note on the testing strategy: as mentioned above, we don't need to use
an i18n parser, but we don't **not** need to use one if the parser
does not heavily modify the template AST. For this reason, the tests
target the functionality of not modifying a template with i18n metadata
rather than testing that the language service does not use an i18n parser.

In some cases, where a module imports a dependency
but does not actually use it, UMD bundlers may remove
the dependency parameter from the UMD factory function
definition.
For example:
```
import * as x from 'x';
import * as z from 'z';
export const y = x;
```
may result in a UMD bundle including:
```
(function (global, factory) {
typeof exports === 'object' && typeof module !== 'undefined' ?
factory(exports, require('x'), require('z')) :
typeof define === 'function' && define.amd ?
define(['exports', 'x', 'z'], factory) :
(global = global || self, factory(global.myBundle = {}, global.x));
}(this, (function (exports, x) { 'use strict';
...
})));
```
Note that while the `z` dependency is provide in the call,
the factory itself only accepts `exports` and `x` as parameters.
Previously ngcc appended new dependencies to the end of the factory
function, but this breaks in the above scenario. Now the new
dependencies are prefixed at the front of parameters/arguments
already in place.

This commit fixes this by additionally processing the imports in the

The main logic of the `InheritDefinitionFeature` is to go through the prototype chain of a given Component and merge all Angular-specific information onto that Component def. The problem happens in case there is a Component in a hierarchy that also contains the `InheritDefinitionFeature` (i.e. it extends some other Component), so it inherits all Angular-specific information from its super class. As a result, the root Component may end up having duplicate information inherited from different Components in hierarchy.
Let's consider the following structure: `GrandChild` extends `Child` that extends `Base` and the `Base` class has a `HostListener`. In this scenario `GrandChild` and `Child` will have `InheritDefinitionFeature` included into the `features` list. The processing will happend in the following order:
- `Child` inherits `HostListener` from the `Base` class
- `GrandChild` inherits `HostListener` from the `Child` class
- since `Child` has a parent, `GrandChild` also inherits from the `Base` class
The result is that the `GrandChild` def has duplicated host listener, which is not correct.
This commit introduces additional logic that checks whether we came across a def that has `InheritDefinitionFeature` feature (which means that this def already inherited information from its super classes). If that's the case, we skip further fields-related inheritance logic, but keep going though the prototype chain to look for super classes that contain other features (like NgOnChanges), that we need to invoke for a given Component def.

Currently, the language service provides completions in a template node
attribute by first checking if the attribute contains template bindings
to provide completions for, and then providing completions for the
expression in the attribute.
In the latter case, the expression AST was being constructed
"synthetically" inside the language service, in particular declaring the
expression to be a `PropertyRead` with an implicit receiver.
Unfortunately, this AST can be incorrect if the expression is actually a
property read on a component property receiver (e.g. when reading
`key` in the expression `obj.key`, `obj` is the receiver).
The fix is pretty simple - rather than a synthetic construction of the
AST, ask the expression parser to parse the expression in the attribute.

The compiler has a translation mechanism to convert from an Angular
`Type` to a `ts.TypeNode`, as appropriate. Prior to this change, it
would translate certain Angular expressions into their value equivalent
in TypeScript, instead of the correct type equivalent. This was possible
as the `ExpressionVisitor` interface is not strictly typed, with `any`s
being used for return values.
For example, a literal object was translated into a
`ts.ObjectLiteralExpression`, containing `ts.PropertyAssignment` nodes
as its entries. This has worked without issues as their printed
representation is identical, however it was incorrect from a semantic
point of view. Instead, a `ts.TypeLiteralNode` is created with
`ts.PropertySignature` as its members, which corresponds with the type
declaration of an object literal.

In Ivy's template type checker, type constructors are created for all
directive types to allow for accurate type inference to work. The type
checker has two strategies for dealing with such type constructors:
1. They can be emitted local to the type check block/type check file.
2. They can be emitted as static `ngTypeCtor` field into the directive
itself.
The first strategy is preferred, as it avoids having to update the
directive type which would cause a more expensive rebuild. However, this
strategy is not suitable for directives that have constrained generic
types, as those constraints would need to be present on the local type
constructor declaration. This is not trivial, as it requires that any
type references within a type parameter's constraint are imported into
the local context of the type check block.
For example, lets consider the `NgForOf` directive from '@angular/core'
looks as follows:
```typescript
import {NgIterable} from '@angular/core';
export class NgForOf<T, U extends NgIterable<T>> {}
```
The type constructor will then have the signature:
`(o: Pick<i1.NgForOf<T, U>, 'ngForOf'>) => i1.NgForOf<T, U>`
Notice how this refers to the type parameters `T` and `U`, so the type
constructor needs to be emitted into a scope where those types are
available, _and_ have the correct constraints.
Previously, the template type checker would detect the situation where a
type parameter is constrained, and would emit the type constructor
using strategy 2; within the directive type itself. This approach makes
any type references within the generic type constraints lexically
available:
```typescript
export class NgForOf<T, U extends NgIterable<T>> {
static ngTypeCtor<T = any, U extends NgIterable<T> = any>
(o: Pick<NgForOf<T, U>, 'ngForOf'>): NgForOf<T, U> { return null!; }
}
```
This commit introduces the ability to emit a type parameter with
constraints into a different context, under the condition that it can
be imported from an absolute module. This allows a generic type
constructor to be emitted into a type check block or type check file
according to strategy 1, as imports have been generated for all type
references within generic type constraints. For example:
```typescript
import * as i0 from '@angular/core';
import * as i1 from '@angular/common';
const _ctor1: <T = any, U extends i0.NgIterable<T> = any>
(o: Pick<i1.NgForOf<T, U>, 'ngForOf'>) => i1.NgForOf<T, U> = null!;
```
Notice how the generic type constraint of `U` has resulted in an import
of `@angular/core`, and the `NgIterable` is transformed into a qualified
name during the emitting process.

In the past, only the starting index of an expression Token has been
recorded, so a parser could demarkate the span of a token only by the
start locations of two tokens. This may lead to trailing whitespace
being included in the token span:
```html
{{ token1 + token2 }}
^^^^^^^^^ recorded span of `token1`
```
It's also not enough for a parser to determine the end of a token by
adding the length of the token value to the token's start location,
because lexed expression values may not exactly reflect the source code.
For example, `"d\\"e"` is lexed as a string token whose value is `d"e`.
Instead, this commit adds a `end` field to expression tokens. `end`
is one past the last index of the token source code. This will enable a
parser to determine the span of a token just by looking at that token.
This is a breaking change because the contructor interface of `Token`
has changed.

This commit fixes a bug in which we do testing for completions.
Subsequently, this exposes another bug in our implementation whereby
suggestions are not provided in "ngFor" where there should have been.
Currently, multiple test cases are grouped together in a single
template. This requires the template to be somewhat complete so that
test cases that depend on variables declared earlier would pass.
Consider the following example:
```
template: `
<div *ngFor="let ~{for-person}person of ~{for-people}people">
<span>Name: {{~{for-interp-person}person.~{for-interp-name}name}}</span>
<span>Age: {{person.~{for-interp-age}age}}</span>
</div>`,
```
In order to test `~{for-interp-person}`, `people` has to be included after
`~{for-people}`. This means the test case for `~{for-people}` is not
reflective of the actual use case because the variable is already there!
In real case, the expression would be incomplete, and our implementation
failed to take that into account.
This commit breaks such test into individual tests, and fix the bugs in
the underlying implementation.

Angular View Engine uses global knowledge to compile the following code:
```typescript
export class Base {
constructor(private vcr: ViewContainerRef) {}
}
@Directive({...})
export class Dir extends Base {
// constructor inherited from base
}
```
Here, `Dir` extends `Base` and inherits its constructor. To create a `Dir`
the arguments to this inherited constructor must be obtained via dependency
injection. View Engine is able to generate a correct factory for `Dir` to do
this because via metadata it knows the arguments of `Base`'s constructor,
even if `Base` is declared in a different library.
In Ivy, DI is entirely a runtime concept. Currently `Dir` is compiled with
an ngDirectiveDef field that delegates its factory to `getInheritedFactory`.
This looks for some kind of factory function on `Base`, which comes up
empty. This case looks identical to an inheritance chain with no
constructors, which works today in Ivy.
Both of these cases will now become an error in this commit. If a decorated
class inherits from an undecorated base class, a diagnostic is produced
informing the user of the need to either explicitly declare a constructor or
to decorate the base class.

Previously, ngtsc would perform scope analysis (which directives/pipes are
available inside a component's template) and template type-checking of that
template as separate steps. If a component's scope was somehow invalid (e.g.
its NgModule imported something which wasn't another NgModule), the
component was treated as not having a scope. This meant that during template
type-checking, errors would be produced for any invalid expressions/usage of
other components that should have been in the scope.
This commit changes ngtsc to skip template type-checking of a component if
its scope is erroneous (as opposed to not present in the first place). Thus,
users aren't overwhelmed with diagnostic errors for the template and are
only informed of the root cause of the problem: an invalid NgModule scope.

The template type checker generates TypeScript expressions for any
expression that occurs in a template, so that TypeScript can check it
and produce errors. Some expressions as they occur in a template may be
translated into TypeScript code multiple times, for instance a binding
to a directive input that has a template guard.
One example would be the `NgIf` directive, which has a template guard to
narrow the type in the template as appropriate. Given the following
template:
```typescript
@Component({
template: '<div *ngIf="person">{{ person.name }}</div>'
})
class AppComponent {
person?: { name: string };
}
```
A type check block (TCB) with roughly the following structure is
created:
```typescript
function tcb(ctx: AppComponent) {
const t1 = NgIf.ngTypeCtor({ ngIf: ctx.person });
if (ctx.person) {
"" + ctx.person.name;
}
}
```
Notice how the `*ngIf="person"` binding is present twice: once in the
type constructor call and once in the `if` guard. As such, TypeScript
will check both instances and would produce duplicate errors, if any
were found.
Another instance is when the safe navigation operator is used, where an
expression such as `person?.name` is emitted into the TCB as
`person != null ? person!.name : undefined`. As can be seen, the
left-hand side expression `person` occurs twice in the TCB.
This commit adds the ability to insert markers into the TCB that
indicate that any errors within the expression should be ignored. This
is similar to `@ts-ignore`, however it can be applied more granularly.

Previously, the type checker would compute an absolute source span by

start of the file. This information is now directly available on an
expression AST node in the `AST.sourceSpan` property, which can be used

Now that the source to typings matching is able to handle

Previously the identifiers used in the typings files were the same as
those used in the source files.
When the typings files and the source files do not match exactly, e.g.
when one of them is flattened, while the other is a deep tree, it is
possible for identifiers to be renamed.
This commit ensures that the correct identifier is used in typings files

The naïve matching algorithm we previously used to match declarations in
source files to declarations in typings files was based only on the name
of the thing being declared. This did not handle cases where the declared
item had been exported via an alias - a common scenario when one of the two
file sets (source or typings) has been flattened, while the other has not.
The new algorithm tries to overcome this by creating two maps of export
name to declaration (i.e. `Map<string, ts.Declaration>`).
One for the source files and one for the typings files.
It then joins these two together by matching export names, resulting in a
new map that maps source declarations to typings declarations directly
(i.e. `Map<ts.Declaration, ts.Declaration>`).
This new map can handle the declaration names being different between the
source and typings as long as they are ultimately both exported with the
same alias name.
Further more, there is one map for "public exports", i.e. exported via the
root of the source tree (the entry-point), and another map for "private
exports", which are exported from individual files in the source tree but
not necessarily from the root. This second map can be used to "guess"
the mapping between exports in a deep (non-flat) file tree, which can be
used by ngcc to add required private exports to the entry-point.

deployed stable version of the docs web-app at https://angular.io/. In
order for the tests to be compatible with the deployed version of the
web-app (which gets deployed from the stable branch), the stable branch
is checked out in git as part of the CI job.
Previously, we only checked out the `aio/` directory from the stable

long as the commands used to run the tests do not rely on code outside
of `aio/`. However, it turns out that there _is_ code outside of `aio/`
that affects the executed commands: It is our vendored version of yarn
(in `third_party/github.com/yarnpkg/`), which overwrites the global yarn
installed on the docker image on CI and must match the version range
specified in `aio/package.json > engines`.
Using the yarn version checked out from the master branch with the
`aio/` code checked out from the stable branch can lead to failures
such as [this one][1].
This commit fixes the problem by checking out both the `aio/` and
`third_party/github.com/yarnpkg/` directories from the stable branch and

certain scripts (such as `.circleci/get-vendored-yarn-path.js`) that are
not available on the stable branch. Therefore, we should only check out
the necessary bits from the stable branch.

NgModel internally coerces any arbitrary value that will assigned
to the `disabled` `@Input` to a boolean. This has been done to
support the common case where developers set the disabled attribute
without a value. For example:
```html
<input type="checkbox" [(ngModel)]="value" disabled>
```
This worked in View Engine without any errors because inputs were
not strictly checked. In Ivy though, developers can opt-in into
strict template type checking where the attribute would be flagged.
This is because the `NgModel#isDisabled` property type-wise only
accepts a `boolean`. To ensure that the common pattern described
above can still be used, and to reflect the actual runtime behavior,
we should add an acceptance member that makes it work without type
checking errors.

this doesn't look easy because the current ngtsc switch logic seems to
be unidirectional (only PRE_R3 to POST_R3).
2. Updating the legacy setup to run with Ivy. This sounds like the easiest
solution at first.. but it turns out to be way more complicated. Packages
would need to be built with ngtsc using legacy tools (i.e. first building
the compiler-cli; and then building packages) and View Engine only tests
would need to be determined and filtered out. Basically it will result in
re-auditing all test targets. This is contradictory to the fact that we have
this information in Bazel already.
3. Creating a new job that runs tests on Saucelabs with Bazel. We specify
fine-grained test targets that should run. This would be a good start

A quirk of the Angular template parser is that when parsing templates in the
"default" mode, with options specified by the user, the source mapping
information in the template AST may be inaccurate. As a result, the compiler
parses the template twice: once for "emit" and once to produce an AST with
accurate sourcemaps for diagnostic production.
Previously, only the first parse was performed during analysis. The second
parse occurred during the template type-checking phase, just in time to
produce the template type-checking file.
However, with the reuse of analysis results during incremental builds, it
makes more sense to do the diagnostic parse eagerly during analysis so that
the work isn't unnecessarily repeated in subsequent builds. This commit
refactors the `ComponentDecoratorHandler` to do both parses eagerly, which
actually cleans up some complexity around template parsing as well.

1. Avoid the object spread operator within the constructor, as the

optimize well compared to a hardcoded object literal. This results in a
significant performance improvement. Because of the straight-forward
object literal, the VM is now much better able to optimize the memory
allocations which makes a significant difference as the
`PlainCharacterCursor` constructor is called in tight loops.
2. Reduce the number of `CharacterCursor` clones. Although cloning
itself is now much faster because of the optimization above, several
clone operations were not necessary.
Combined, these changes reduce the total time spent in the

The new algorithm implemented by this commit is such:
1) Each incremental build starts with knowledge of the last known good
dependency graph and analysis results from the last successful build,
plus of course information about the set of files changed.
2) The previous dependency graph's information is used to determine the
set of source files which have "logically" changed. A source file is
considered logically changed if it or any of its dependencies have
physically changed (on disk) since the last successful compilation. Any
logically unchanged dependencies have their dependency information copied
over to the new dependency graph.
3) During the `TraitCompiler`'s loop to consider all source files in the
program, if a source file is logically unchanged then its previous
analyses are "adopted" (and their 'register' steps are run). If the file
is logically changed, then it is re-analyzed as usual.
4) Then, incremental build proceeds as before, with the new dependency graph
being used to determine the set of files which require re-emitting.
This analysis reuse avoids template parsing operations in many circumstances
and significantly reduces the time it takes ngtsc to rebuild a large
application.
Future work will increase performance even more, by tackling a variety of
other opportunities to reuse or avoid work.

Previously 'analyze' in the various `DecoratorHandler`s not only extracts
information from the decorators on the classes being analyzed, but also has
several side effects within the compiler:
* it can register metadata about the types involved in global metadata
trackers.
* it can register information about which .ngfactory symbols are actually
needed.
In this commit, these side-effects are moved into a new 'register' phase,
which runs after the 'analyze' step. Currently this is a no-op refactoring
as 'register' is always called directly after 'analyze'. In the future this
opens the door for re-use of prior analysis work (with only 'register' being
called, to apply the above side effects).
Also as part of this refactoring, the reification of NgModule scope
information into the incremental dependency graph is moved to the
`NgtscProgram` instead of the `TraitCompiler` (which now only manages trait
compilation and does not have other side effects).
PR Close#34288
Prior to this commit, the `IvyCompilation` tracked the state of each matched
`DecoratorHandler` on each class in the `ts.Program`, and how they
progressed through the compilation process. This tracking was originally
simple, but had grown more complicated as the compiler evolved. The state of
each specific "target" of compilation was determined by the nullability of
a number of fields on the object which tracked it.
This commit formalizes the process of compilation of each matched handler
into a new "trait" concept. A trait is some aspect of a class which gets
created when a `DecoratorHandler` matches the class. It represents an Ivy
aspect that needs to go through the compilation process.
Traits begin in a "pending" state and undergo transitions as various steps
of compilation take place. The `IvyCompilation` class is renamed to the
`TraitCompiler`, which manages the state of all of the traits in the active
program.
Making the trait concept explicit will support future work to incrementalize
the expensive analysis process of compilation.

The `ModuleWithProviders` type has an optional type parameter that
should be specified to indicate what NgModule class will be provided.
This enables the Ivy compiler to statically determine the NgModule type
from the declaration files. This type parameter will become required in
the future, however to aid in the migration the compiler will detect
code patterns where using `ModuleWithProviders` as return type is
appropriate, in which case it transforms the emitted .d.ts files to
include the generic type argument.
This should reduce the number of occurrences where `ModuleWithProviders`
is referenced without its generic type argument.

The metadata collector for View Engine compilations emits error symbols
for static class members that have not been initialized, which prevents
a library from building successfully when `strictMetadataEmit` is
enabled, which is recommended for libraries to avoid issues in library
consumers. This is troublesome for libraries that are adopting static
members for the Ivy template type checker: these members don't need a
value assignment as only their type is of importance, however this
causes metadata errors. As such, a library used to be required to
initialize the special static members to workaround this error,
undesirably introducing a code-size overhead in terms of emitted
JavaScript code.
This commit modifies the collector logic to specifically ignore
the special static members for Ivy's template type checker, preventing
any errors from being recorded during the metadata collection.
PR Close#34296
For Ivy's template type checker it is possible to let a directive
specify static members to allow a wider type for some input:
```typescript
export class MatSelect {
@Input() disabled: boolean;
static ngAcceptInputType_disabled: boolean | string;
}
```
This allows a binding to the `MatSelect.disabled` input to be of type
boolean or string, whereas the `disabled` property itself is only of
type boolean.
Up until now, any static `ngAcceptInputType_*` property was not
inherited for subclasses of a directive class. This is cumbersome, as
the directive's inputs are inherited, so any acceptance member should as
well. To resolve this limitation, this commit extends the flattening of
directive metadata to include the acceptance members.

Previously, ternary expressions were emitted as:
condExpr ? trueCase : falseCase
However, this causes problems when ternary operations are nested. In
particular, a template expression of the form:
a?.b ? c : d
would have compiled to:
a == null ? null : a.b ? c : d
The ternary operator is right-associative, so that expression is interpreted
as:
a == null ? null : (a.b ? c : d)
when in reality left-associativity is desired in this particular instance:
(a == null ? null : a.b) ? c : d
This commit adds a check in the expression translator to detect such
left-associative usages of ternaries and to enforce such associativity with
parentheses when necessary.

Previously the `rootDir` was set to the entry-point path but

Angular CDK.
Instead the `rootDir` should be the containing package path, which is
guaranteed to include all the source for the entry-point.
---
A symptom of this is an error when ngcc is trying to process the source of
an entry-point format after the entry-point's typings have already been
processed by a previous processing run.
During processing the `_toR3Reference()` function gets called which in turn
makes a call to `ReflectionHost.getDtsDeclaration()`. If the typings files
are also being processed this returns the node from the dts typings files.
But if we have already processed the typings files and are now processing
only an entry-point format without typings, the call to
`ReflectionHost.getDtsDeclaration()` returns `null`.
When this value is `null`, a JS `valueRef` is passed through as the DTS
`typeRef` to the `ReferenceEmitter`. In this case, the `ReferenceEmitter`
fails during `emit()` because no `ReferenceEmitStrategy` is able to provide
an emission:
1) The `LocalIdentifierStrategy` is not able help because in this case
`ImportMode` is `ForceNewImport`.
2) The `LogicalProjectStrategy` cannot find the JS file below the `rootDir`.
The second strategy failure is fixed by this PR.

The local Angular packages used to build `aio/` when running
`yarn setup-local`/`yarn build-local` (and related commands), are built
by bazel. Bazel, determines the version to use for these locally built
packages based on the latest tag for a commit on the current branch.
(This works as expected during the release, because the packages are
built on the correct branch with up-to-date tags.)
During local development, however, this often leads to generating older
versions than what the current `@angular/cli` version is compatible
with, if the user has not fetched the latest tags from `angular/angular`
or the branch has not been rebased recently.
Previously, the above (common) situation would result in a build error
by the CLI. (Note that this would be a false error, because in this case
the version set by bazel would not reflect the actual version of the
local packages.) The solution would be for the user to fetch the latest
tags from `angular/angular`, rebase their branch and run a bazel build
again (ensuring that it would actually build anew and not emit cached
artifacts). This was cumbersome and most people didn't even know about
it.
This commit avoids this error and the associated pain-points by
overwriting the versions of the installed local packages with fake
versions based on the ones in the lockfile, which are guaranteed to be

The local variables `i` and `isFirst` are determined to have a type of
`Hero`, when actually their types are `number` and `boolean`,
respectively.
This commit fixes this bug by checking if the value of a variable in an
`*ngFor` expression is known to be an export and assigning the variable
the type of that export value. Only if the variable does not alias an
export is it typed with the binding value of the `*ngFor` expression.

Prior to this commit, the unknown element can happen twice for AOT-compiled components: once during compilation and once again at runtime. Due to the fact that `schemas` information is not present on Component and NgModule defs after AOT compilation, the second check (at runtime) may fail, even though the same check was successful at compile time.

When creating synthesized tagged template literals, one must provide both
the "cooked" text and the "raw" (unparsed) text. Previously there were no
good APIs for creating the AST nodes with raw text for such literals.
Recently the APIs were improved to support this, and they do an extra
check to ensure that the raw text parses to be equal to the cooked text.
It turns out there is a bug in this check -

In order to keep integration tests on CI as determinitstic as possible,
we need to ensure that the same dependencies (including transitive ones)
are installed each time. One way to ensure that is using a lockfile
(such as `yarn.lock`) to pin the dependencies to exact versions. This
works as long as the lockfile itself is in-sync with the corresponding
`package.json`, which specifies the dependencies.
Ideally, we would run `yarn install` with the `--frozen-lockfile` option
to verify that the lockfile is in-sync with `package.json`, but we
cannot do that for integration projects, because we want to be able to
install the locally built Angular packages). Therefore, we must manually
esnure that the integration project lockfiles remain in-sync, which is
error-prone.
This commit introduces a helper script that performs some checks on each
project's (non-local) dependencies:
- Ensure that exact versions (not version ranges) are specified in
`package.json`. This reduces the probability of installing a breaking
version of a direct or transitive dependency, in case of an
out-of-sync lockfile.
- Ensure that the lockfile is in-sync with `package.json` wrt these
dependencies.
While these checks are not full-proof, they provide yet another line of
defense against indeterminism.
PR Close#33968
Since we cannot run `yarn install` with the `--frozen-lockfile` option
(because we want to be able to install the locally built Angular
packages), integration project lockfiles are susceptible to getting
out-of-sync with the corresponding `package.json`. When this happens,
yarn will install the latest available version that satisfies the
version range specified in `package.json`.
This commit adds another line of defense, by specifying exact versions
for the dependencies in `package.json` files (i.e. `1.33.7` instead of
`^1.33.0`). While transitive dependencies will be unpinned, this still
ensures that the same version of direct dependencies will be installed
in case of an out-of-sync lockfile, thus reducing the probability of
random failures.
PR Close#33968
In the `integration_test` CircleCI job, we run `yarn install` on all
projects in the `integration/` directory. If a project has no lockfile
or if the lockfile is out-of-sync with the corresponding `package.json`
file, then the installed dependency versions are no longer pinned, which
can result in different versions being installed between different runs
of the same job (if, for example, a new version is released for a
package) and breaks hermeticity.
This could be prevented by using the `--frozen-lockfile` option with
`yarn install`, but this is not possible with the current setup, because
yarn needs to be able to install the locally built Angular packages,
whose checksums will be different from the ones in the lockfile.
Therefore, we have to manually ensure that the lockfiles remain in-sync
with the corresponding `package.json` files for the rest of the
dependencies.
For example, previously, [cli-hello-world-lazy/yarn.lock][1] had an
entry for `@angular-devkit/build-angular@0.900.0-next.9` (pinned to
`0.900.0-next.9`), but [cli-hello-world-lazy/package.json][2] specified
the `@angular-devkit/build-angular` version as `^0.900.0-rc.0` (note the
leading caret). As a result, since the version in the lock file does not
much the one in `package.json`, the lockfile is ignored and the latest
available version that matches `^0.900.0-rc.0` is installed.
This, for example, started causing unrelated CI failures ([example][3]),
when `@angular-devkit/build-angular@9.0.0-rc.3` was released with a size
improvement.
This commit ensures that all integration projects have a lockfile and
that lockfiles are up-to-date (with the current `package.json` files).

Commit 53fc2ed8bf added support for
determining index types accessed using index signatures, but did not
include support for index types accessed using dot notation:
```typescript
const obj<T>: { [key: string]: T };
obj['stringKey']. // gets `T.` completions
obj.stringKey. // did not peviously get `T.` completions
```
This adds support for determining an index type accessed via dot
notation by rigging an object's symbol table to return the string index
signature type a property access refers to, if that property does not
explicitly exist on the object. This is very similar to @ivanwonder's
work in #29811.
`SymbolWrapper` now takes an additional parameter to explicitly set the
type of the symbol wrapped. This is done because
`SymbolTableWrapper#get` only has access to the symbol of the index
type, _not_ the index signature symbol itself. An attempt to get the
type of the index type will give an error.

This commit fixes a compatibility bug where pre-order lifecycle
hooks (onInit, doCheck, OnChanges) for directives on the same

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.

The change type was only recorded for `aio/` and was not correct anyway.
For example:
- It considered `package.json` changes as `application` (even if only
`package.json` and `yarn.lock` had changed).
- It failed to account for changes in `@angular/*` dependencies, when
using the locally built Angular packages (instead reporting them as
`other`).
- It only looked at the last commit, so it failed to provide accurate
information for multi-commit builds (which are rare, but possible).
For the above reasons (and because there is no straight-forward way of
fixing it), this commit removes the change type from the uploaded data.

As part of the `payload-size` npm script in `aio/package.json` (which is
run on CI), the sizes of the angular.io app bundles are checked to
ensure they do not exceed certain limits and are also uploaded to
Firebase to be available for later analysis. The uploaded data include
the type of the changes (dependencies only, application only, or both).
The type of changes is inferred by looking at the files that have
changed inside the `aio/` directory.
When the `payload-size.sh` script was first introduced, the only files
that could affect bundle sizes were inside the `aio/` directory.
Therefore, the script would skip uploading the data and checking the
sizes if no changes were detected inside the `aio/` directory.
However, this assumption stopped being valid over time. For example:
- We started tracking/checking bundle sizes when building the angular.io
app with the locally built Angular packages (which live outside the
`aio/` directory.
- Due to CircleCI limitations, the `CI_COMMIT_RANGE` environment
variable (which is used for determining what files have been affected)
stopped reflecting the whole commit range of the build and only
included the last commit instead.
Based on the above, there were many cases were size data would not be
uploaded to Firebase, even when they may have been affected (because the
affecting changes were outside `aio/` - e.g. in framework packages).
This makes it harder to analyze size regressions, because important
data-points are missing.
Even worse, in these cases, the sizes were not even checked against the
specified limits, thus making it possible for size regressions to go
unnoticed (unless caught by other similar tests).
This commit fixes the `scripts/ci/payload-size.sh` script to always
track and check payload sizes for angular.io bundles.
NOTE: This change will result in more data being recorded (i.e.
recording data when it is not possible for the bundle sizes to
have been affected by the changes). This is still preferable to
failing to record and/or check when sizes could have been
affected.

Previously, our incremental build system kept track of the changes between
the current compilation and the previous one, and used its knowledge of
inter-file dependencies to evaluate the impact of each change and emit the
right set of output files.
However, a problem arose if the compiler was not able to extract a
dependency graph successfully. This typically happens if the input program
contains errors. In this case the Angular analysis part of compilation is
never executed.
If a file changed in one of these failed builds, in the next build it
appears unchanged. This means that the compiler "forgets" to emit it!
To fix this problem, the compiler needs to know the set of changes made
_since the last successful build_, not simply since the last invocation.
This commit changes the incremental state system to much more explicitly
pass information from the previous to the next compilation, and in the
process to keep track of changes across multiple failed builds, until the
program can be analyzed successfully and the results of those changes
incorporated into the emit plan.

be used to refer to an exported variable. This variable would be

- Ensure `src/main-specs.ts` is not included in the zip that does not

logic in our zip-builder that renamed `main-*.ts` files to `main.ts`

This commit transforms the setClassMetadata calls generated by ngtsc from:
```typescript
/*@__PURE__*/ setClassMetadata(...);
```
to:
```typescript
/*@__PURE__*/ (function() {
setClassMetadata(...);
})();
```
Without the IIFE, terser won't remove these function calls because the
function calls have arguments that themselves are function calls or other
impure expressions. In order to make the whole block be DCE-ed by terser,
we wrap it into IIFE and mark the IIFE as pure.
It should be noted that this change doesn't have any impact on CLI* with
build-optimizer, which removes the whole setClassMetadata block within
the webpack loader, so terser or webpack itself don't get to see it at
all. This is done to prevent cross-chunk retention issues caused by
webpack's internal module registry.
* actually we do expect a short-term size regression while
https://github.com/angular/angular-cli/pull/16228
is merged and released in the next rc of the CLI. But long term this
change does nothing to CLI + build-optimizer configuration and is done
primarly to correct the seemingly correct but non-function PURE annotation
that builds not using build-optimizer could rely on.

NgModules in Ivy have a definition which contains various different bits
of metadata about the module. In particular, this metadata falls into two
categories:
* metadata required to use the module at runtime (for bootstrapping, etc)
in AOT-only applications.
* metadata required to depend on the module from a JIT-compiled app.
The latter metadata consists of the module's declarations, imports, and
exports. To support JIT usage, this metadata must be included in the
generated code, especially if that code is shipped to NPM. However, because
this metadata preserves the entire NgModule graph (references to all
directives and components in the app), it needs to be removed during
optimization for AOT-only builds.
Previously, this was done with a clever design:
1. The extra metadata was added by a function called `setNgModuleScope`.
A call to this function was generated after each NgModule.
2. This function call was marked as "pure" with a comment and used
`noSideEffects` internally, which causes optimizers to remove it.
The effect was that in dev mode or test mode (which use JIT), no optimizer
runs and the full NgModule metadata was available at runtime. But in
production (presumably AOT) builds, the optimizer runs and removes the JIT-
specific metadata.
However, there are cases where apps that want to use JIT in production, and
still make an optimized build. In this case, the JIT-specific metadata would
be erroneously removed. This commit solves that problem by adding an
`ngJitMode` global variable which guards all `setNgModuleScope` calls. An
optimizer can be configured to statically define this global to be `false`
for AOT-only builds, causing the extra metadata to be stripped.
A configuration for Terser used by the CLI is provided in `tooling.ts` which
sets `ngJitMode` to `false` when building AOT apps.

The Ivy template type-checker is capable of inferring the type of a
structural directive (such as NgForOf<T>). Previously, this was done with
fullTemplateTypeCheck: true, even if strictTemplates was false. View Engine
previously did not do this inference, and so this causes breakages if the
type of the template context is not what the user expected.
In particular, consider the template:
```html
<div *ngFor="let user of users as all">
{{user.index}} out of {{all.length}}
</div>
```
As long as `users` is an array, this seems reasonable, because it appears
that `all` is an alias for the `users` array. However, this is misleading.
In reality, `NgForOf` is rendered with a template context that contains
both a `$implicit` value (for the loop variable `user`) as well as a
`ngForOf` value, which is the actual value assigned to `all`. The type of
`NgForOf`'s template context is `NgForContext<T>`, which declares `ngForOf`'s
type to be `NgIterable<T>`, which does not have a `length` property (due to
its incorporation of the `Iterable` type).
This commit stops the template type-checker from inferring template context
types unless strictTemplates is set (and strictInputTypes is not disabled).

Previously, the ngtsc compiler attempted to reuse analysis work from the
previous program during an incremental build. To do this, it had to prove
that the work was safe to reuse - that no changes made to the new program
would invalidate the previous analysis.
The implementation of this had a significant design flaw: if the previous
program had errors, the previous analysis would be missing significant
information, and the dependency graph extracted from it would not be
sufficient to determine which files should be re-analyzed to fill in the
gaps. This often meant that the build output after an error was resolved
would be wholly incorrect.
This commit switches ngtsc to take a simpler approach to incremental
rebuilds. Instead of attempting to reuse prior analysis work, the entire
program is re-analyzed with each compilation. This is actually not as
expensive as one might imagine - analysis is a fairly small part of overall
compilation time.
Based on the dependency graph extracted during this analysis, the compiler
then can make accurate decisions on whether to emit specific files. A new
suite of tests is added to validate behavior in the presence of source code
level errors.
This new approach is dramatically simpler than the previous algorithm, and
should always produce correct results for a semantically correct program.s

By clearing `sessionStorage` and unsubscribing from `Location` events,
after each test, we reduce the possibility of potential
[spooky action at a distance][1]-type of failures in the future.
This does not have an impact on the actual app, since `ScrollService` is
currently expected to live throughout the lifetime of the app. Still,
unsubscribing from `Location` events keeps the code consistent with how
other `ScrollService` listeners are handled (e.g. for `window` events).

`ScrollService` subscribes to global `window` events and mutates global
state in the listener (e.g. read/write values from/to `sessionStorage`).
Therefore, we need to always call its `ngOnDestroy()` method to

In f69c6e204, a new testcase was introduced that was not destroyed. As a

Originally, QueryList implemented Iterable and provided a Symbol.iterator
on its prototype. This caused issues with tree-shaking, so QueryList was
refactored and the Symbol.iterator added in its constructor instead. As
part of this change, QueryList no longer implemented Iterable directly.
Unfortunately, this meant that QueryList was no longer assignable to
Iterable or, consequently, NgIterable. NgIterable is used for NgFor's input,
so this meant that QueryList was not usable (in a type sense) for NgFor
iteration. View Engine's template type checking would not catch this, but
Ivy's did.
As a fix, this commit adds the declaration (but not the implementation) of
the Symbol.iterator function back to QueryList. This has no runtime effect,
so it doesn't affect tree-shaking of QueryList, but it ensures that
QueryList is assignable to NgIterable and thus usable with NgFor.

Previously, the compiler assumed that all TS files logically within a
project existed under one or more "root directories". If the TS compiler
option `rootDir` or `rootDirs` was set, they would dictate the root
directories in use, otherwise the current directory was used.
Unfortunately this assumption was unfounded - it's common for projects
without explicit `rootDirs` to import from files outside the current
working directory. In such cases the `LogicalProjectStrategy` would attempt
to generate imports into those files, and fail. This would lead to no
`ReferenceEmitStrategy` being able to generate an import, and end in a
compiler assertion failure.
This commit introduces a new strategy to use when there are no `rootDirs`
explicitly present, the `RelativePathStrategy`. It uses simpler, filesystem-
relative paths to generate imports, even to files above the current working
directory.

In #32902 a bug was supposedly fixed where internal classes as used

In flat bundle formats, multiple classes that have the same name can be
suffixed to become unique. In ES5-like bundles this results in the outer
declaration from having a different name from the "implementation"
declaration within the class' IIFE, as the implementation declaration
may not have been suffixed.
As an example, the following code would fail to have a `Directive`
decorator as ngcc would search for `__decorate` calls that refer to
`AliasedDirective$1` by name, whereas the `__decorate` call actually
uses the `AliasedDirective` name.
```javascript

function AliasedDirective() {}

While processing class metadata, ngtsc generates a `setClassMetadata()`
call which (among other things) contains info about property decorators.
Previously, processing getter/setter pairs with some of ngcc's
`ReflectionHost`s resulted in multiple metadata entries for the same
property, which resulted in duplicate object keys, which in turn causes
an error in ES5 strict mode.
This commit fixes it by ensuring that there are no duplicate property
names in the `setClassMetadata()` calls.
In addition, `generateSetClassMetadataCall()` is updated to treat
`ClassMember#decorators: []` the same as `ClassMember.decorators: null`
(i.e. omitting the `ClassMember` from the generated `setClassMetadata()`
call). Alternatively, ngcc's `ReflectionHost`s could be updated to do
this transformation (`decorators: []` --> `decorators: null`) when
reflecting on class members, but this would require changes in many
places and be less future-proof.
For example, given a class such as:
```ts
class Foo {
@Input() get bar() { return 'bar'; }
set bar(value: any) {}
}
```
...previously the generated `setClassMetadata()` call would look like:
```ts
ɵsetClassMetadata(..., {
bar: [{type: Input}],
bar: [],
});
```
The same class will now result in a call like:
```ts
ɵsetClassMetadata(..., {
bar: [{type: Input}],
});
```

Previously, due to a bug a `Context` with `isStatement: false` could be
returned in places where a `Context` with `isStatement: true` was
requested. As a result, some statements would be unnecessarily wrapped
in parenthesis.
This commit fixes the bug in `Context#withStatementMode` to always
return a `Context` with the correct `isStatement` value. Note that this
does not have any impact on the generated code other than avoiding some
superfluous parenthesis on certain statements.

Currently if a consumer does something like the following, the object literal will be shared across the two elements and any instances of the component template. The same applies to array literals:
```
<div [someDirective]="{}"></div>
<div [someDirective]="{}"></div>
```
These changes make it so that we generate a pure function even if an object is constant so that each instance gets its own object.
Note that the original design for this fix included moving the pure function factories into the `consts` array. In the process of doing so I realized that pure function are also used inside of directive host bindings which means that we don't have access to the `consts`.
These changes also:
* Fix an issue that meant that the `pureFunction0` instruction could only be run during creation mode.
* Make the `getConstant` utility slightly more convenient to use. This isn't strictly required for these changes to work, but I had made it as a part of a larger refactor that I ended up reverting.

In order to speed up bazel build performance delete all rxjs d.ts files
that reference rxjs-compat.
For all ts_library and ng_module rules Bazel generates tsconfig.json file
that explicitly lists all d.ts files found in required npm package.
In case of rxjs, this means that tsconfig contains all d.ts files that
reference rxjs-compat package, which is an interop/backwards compatibility
package not installed in angular/angular repo.
But because tsconfig contains these d.ts files, tsc will try to resolve
them and silently fail. All these lookups are quite expensive and not
cached. This causes significant slowdown of the build under bazel.
This change removes all of these problematic rxjs d.ts files via an npm
postinstall hook. This is not ideal because it solves the problem only
for our repo, but it's a good start.

Prior to this change, ComponentFactory.create function invocation in Ivy retained the content of the host element (in case host element reference or CSS seelctor is provided as an argument).

This commit aligns Ivy and View Engine and makes sure the host element is cleared before component content insertion.

During incremental compilations, ngtsc needs to know which metadata
from a previous compilation can be reused, versus which metadata has to
be recomputed as some dependency was updated. Changes to
directives/components should cause the NgModule in which they are
declared to be recompiled, as the NgModule's compilation is dependent
on its directives/components.
When a dependent source file of a directive/component is updated,
however, a more subtle dependency should also cause to NgModule's source
file to be invalidated. During the reconciliation of state from a
previous compilation into the new program, the component's source file
is invalidated because one of its dependency has changed, ergo the
NgModule needs to be invalidated as well. Up until now, this implicit
dependency was not imposed on the NgModule. Additionally, any change to
a dependent file may influence the module scope to change, so all
components within the module must be invalidated as well.
This commit fixes the bug by introducing additional file dependencies,
as to ensure a proper rebuild of the module scope and its components.

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.

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.

It looks like there was a typo when it originally was
written. As it works right now, the `beforeEach` and

`withBody() function.

Previously the renderers were fixed so that they inserted extra
"adjacent" statements after the last static property of classes.
In order to help the build-optimizer (in Angular CLI) to be able to
tree-shake classes effectively, these statements should also appear
after any helper calls, such as `__decorate()`.
This commit moves the computation of this positioning into the
`NgccReflectionHost` via the `getEndOfClass()` method, which
returns the last statement that is related to the class.

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`.

# VSCode Remote Development - Developing inside a Containers
This folder contains configuration files that can be used to opt into working on this repository in a [Docker container](https://www.docker.com/resources/what-container) via [VSCode](https://code.visualstudio.com/)'s Remote Development feature (see below).
Info on remote development and developing inside a container with VSCode:
- [VSCode: Developing inside a Container](https://code.visualstudio.com/docs/remote/containers)
- [VSCode: Remote Development FAQ](https://code.visualstudio.com/docs/remote/faq)
## Usage
_Prerequisite: [Install Docker](https://docs.docker.com/install) on your local environment._
To get started, read and follow the instuctions in [Developing inside a Container](https://code.visualstudio.com/docs/remote/containers). The [.devcontainer/](.) directory contains pre-configured `devcontainer.json` and `Dockerfile` files, which you can use to set up remote development with a docker container.
In a nutshell, you need to:
- Install the [Remote - Containers](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-containers) extension.
- Copy [recommended-Dockerfile](./recommended-Dockerfile) to `Dockerfile` (and optionally tweak to suit your needs).
- Copy [recommended-devcontainer.json](./recommended-devcontainer.json) to `devcontainer.json` (and optionally tweak to suit your needs).
- Open VSCode and bring up the [Command Palette](https://code.visualstudio.com/docs/getstarted/userinterface#_command-palette).
- Type `Remote-Containers: Open Folder in Container` and choose your local clone of [angular/angular](https://github.com/angular/angular).
The `.devcontainer/devcontainer.json` and `.devcontainer/Dockerfile` files are ignored by git, so you can have your own local versions. We may occasionally update the template files ([recommended-devcontainer.json](./recommended-devcontainer.json), [recommended-Dockerfile](./recommended-Dockerfile)), in which case you will need to manually update your local copies (if desired).
## Updating `recommended-devcontainer.json` and `recommended-Dockerfile`
You can update and commit the recommended config files (which people use as basis for their local configs), if you find that something is broken, out-of-date or can be improved.
Please, keep in mind that any changes you make will potentially be used by many people on different environments. Try to keep these config files cross-platform compatible and free of personal preferences.
# - we trust that people do the right thing and not approve changes they don't feel confident reviewing
# - we use github teams so that we funnel code reviews to the most appropriate reviewer, this is why the team structure is fine-grained
# - we enforce that only approved PRs get merged to ensure that unreviewed code doesn't get accidentally merged
# - we delegate approval rights as much as possible so that we can scale better
# - each group must have at least one person, but several people are preferable to avoid a single point of failure issues
# - most file groups have one or two global approvers groups as fallbacks:
# - @angular/fw-global-approvers: for approving minor changes, large-scale refactorings, and emergency situations.
# - @angular/fw-global-approvers-for-docs-only-changes: for approving minor documentation-only changes that don't require engineering review
# - a small number of file groups have very limited number of reviewers because incorrect changes to the files they guard would have serious consequences (e.g. security, public api)
#
# Configuration nuances:
#
# - This configuration works in conjunction with the protected branch settings that require all changes to be made via pull requests with at least one approval.
# - This approval can come from an appropriate codeowner, or any repo collaborator (person with write access) if the PR is authored by a codeowner.
# - Each codeowners team must have write access to the repo, otherwise their reviews won't count.
#
# In the case of emergency, the repo administrators which include angular-caretaker can bypass this requirement.
