Previously we only searched for package paths below the set of `basePaths`
that were computed from the `basePath` provided to ngcc and the set of
`pathMappings`.
In some scenarios, such as hoisted packages, the entry-point is not within
any of the `basePaths` identified above. For example:
```
project
packages
app
node_modules
app-lib (depends on lib1)
node_modules
lib1 (depends on lib2)
node_modules
lib2 (depends on lib3/entry-point)
lib3
entry-point
```
When CLI is compiling `app-lib` ngcc will be given
`project/packages/app/node_modules` as the `basePath.
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.

Previously, some of the built-in ServiceWorker registration strategies,
namely `registerWithDelay:<timeout>` and `registerWhenStable:<timeout>`,
would register potentially long-running timeout, thus preventing the app
from stabilizing before the timeouts expired. This was especially
problematic for the `registerWhenStable:<timeout>` strategy, which waits
for the app to stabilize, because the strategy itself would prevent the
app from stabilizing and thus the ServiceWorker would always be
registered after the timeout.
This commit fixes this by subscribing to the registration strategy
observable outside the Angular zone, thus not affecting the app's
stabilization.
PR Close#35870
Previously, when using the default ServiceWorker registration strategy
Angular would wait indefinitely for the [app to stabilize][1], before
registering the ServiceWorker script. This could lead to a situation
where the ServiceWorker would never be registered when there was a
long-running task (such as an interval or recurring timeout).
Such tasks can often be started by a 3rd-party dependency (beyond the
developer's control or even without them realizing). In addition, this
situation is particularly hard to detect, because the ServiceWorker is
typically not used during development and on production builds a
previous ServiceWorker instance might be already active.
This commit fixes this by changing the default registration strategy
from `registerWhenStable` to `registerWhenStable:30000`, which will
ensure that the ServiceWorker will be registered after 30s at the
latest, even if the app has not stabilized by then.

This commit allows ngcc to use the `preserveWhitespaces` setting

preservation. But this is already the case in the current ngcc since

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.

This commit publishes the options to be globally available, so that the

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

This commit changes ngcc so that if `errorOnFailedEntryPoint` is false, it will

ngcc is processing the entire node_modules folder and there are some invalid
entry-points that the project doesn't actually use.

Previously, when an entry-point contained code that caused its compilation
to fail, ngcc would exit in the middle of processing, possibly leaving other
entry-points in a corrupt state.
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
workers.

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.

The new `EntryPointManifest` class can read and write a
manifest file that contains all the paths to the entry-points
that have been found in a node_modules folder.
This can be used to speed up finding entry-points in
subsequent runs.
The manifest file stores the ngcc version and hashes of
the package lock-file and project config, since if these
change the manifest will need to be recomputed.

Today, the language service infers the type of variables bound to the
"ngIf" template context member of an NgIf directive, but does not do the
same for the the "$implicit" context member. This commit adds support
for that.

This commit adds fine-grained text spans to TemplateBinding for microsyntax expressions.
1. Source span
By convention, source span refers to the entire span of the binding,
including its key and value.
2. Key span
Span of the binding key, without any whitespace or keywords like `let`
The value span is captured by the value expression AST.
This is part of a series of PRs to fix source span mapping in microsyntax expression.

Currently, when running the ngcc binary directly and provide an invalid option ngcc will not error out and the user might have a hard time telling why ngcc is behaving not as expected.
With this change we now output an actionable error:
```
yarn ngcc --unknown-option
Options:
--version Show version number [boolean]
-s, --source A path (relative to the working directory)
of the `node_modules` folder to process.
[default: "./node_modules"]
-p, --properties An array of names of properties in
package.json to compile (e.g. `module` or
`es2015`)
Each of these properties should hold the
path to a bundle-format.
If provided, only the specified properties
are considered for processing.
If not provided, all the supported format
properties (e.g. fesm2015, fesm5, es2015,
esm2015, esm5, main, module) in the
package.json are considered. [array]
-t, --target A relative path (from the `source` path) to
a single entry-point to process (plus its
dependencies).
--first-only If specified then only the first matching
package.json property will be compiled.
[boolean]
--create-ivy-entry-points If specified then new `*_ivy_ngcc`
entry-points will be added to package.json
rather than modifying the ones in-place.
For this to work you need to have custom
resolution set up (e.g. in webpack) to look
for these new entry-points.
The Angular CLI does this already, so it is
safe to use this option if the project is
being built via the CLI. [boolean]
--legacy-message-ids Render `$localize` messages with legacy
format ids.
The default value is `true`. Only set this
to `false` if you do not want legacy
message ids to
be rendered. For example, if you are not
using legacy message ids in your
translation files
AND are not doing compile-time inlining of
translations, in which case the extra
message ids
would add unwanted size to the final source
bundle.
It is safe to leave this set to true if you
are doing compile-time inlining because the
extra
legacy message ids will all be stripped
during translation.
[boolean] [default: true]
--async Whether to compile asynchronously. This is
enabled by default as it allows
compilations to be parallelized.
Disabling asynchronous compilation may be
useful for debugging.
[boolean] [default: true]
-l, --loglevel The lowest severity logging message that
should be output.
[choices: "debug", "info", "warn", "error"]
--invalidate-entry-point-manifest If this is set then ngcc will not read an
entry-point manifest file from disk.
Instead it will walking the directory tree
as normal looking for entry-points, and
then write a new manifest file.
[boolean] [default: false]
--help Show help [boolean]
Unknown arguments: unknown-option, unknownOption

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.
This commit does not update angular.io.

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.

This commit splits the ngtsc `core` package's api entrypoint, which
previously was a single `api.ts` file, into an api/ directory with multiple
files. This is done to isolate the parts of the API definitions pertaining
to the public-facing `angularCompilerOptions` field in tsconfig.json into a
single file, which will enable a public API guard test to be added in a
future commit.

This commit accomplishes two tasks:
- Fixes the span of queried pipes to only be applied on pipe names
- By consequence, fixes how pipes are located in arguments (previously,
pipes with arguments could not be found because the span of a pipe
uses a relative span, while the template position is absolute)
The screenshots attached to the PR for this commit demonstrate the
change.

PR Close#35986
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.

XLIFF translation files can contain multiple `<file>` elements,
each of which contains translations. In ViewEngine all these
translations are merged into a single translation bundle.
Previously in Ivy only the translations from the last `<file>`
element were being loaded. Now all the translations from each
`<file>` are merged into a single translation bundle.
