Pete Bacon Darwin 26eacd4fcb fix(compiler-cli): ensure `MockFileSystem` handles case-sensitivity (#36859)
Previously this class used the file passed in directly to look up files in the
in-memory mock file-system. But this doesn't match the behaviour of
case-insensitive file-systems. Now the look up is done on the canonical
file paths.

Previously this method was returning the exact opposite value
than the correct one.
Also, calling `this.exists()` causes an infinite recursions,

Paul Gschwendtner 0577bf0e3e refactor: enable ng update migrations for v10 (#36921)
Enables the `ng update` migrations for v10. Status for individual
migrations:

**undecorated-classes-with-di**.

This migration dealt exlusively with inherited constructors and
cases where a derived component was undecorated. In those cases,
the migration added `@Directive()` or copied the inherited decorator
to the derived class.

We don't need to run this migration again because ngtsc throws if
constructor is inherited from an undecorated class. Also ngtsc will
throw if a NgModule references an undecorated class in the declarations.

***undecorated-classes-with-decorated-fields***

This migration exclusively deals with undecorated classes that use
Angular features but are not decorated. Angular features include
the use of lifecycle hooks or class fields with Angular decorators,
such as `@Input()`.

We want to re-run this migration in v10 as we will disable the
compatibility code in ngtsc that detects such undecorated classes
as `@Directive`.

**module-with-providers**:

This migration adds an explicit generic type to `ModuleWithProviders`.
As of v10, the generic type is required, so we need to re-run the
migration again.

**renderer-to-renderer2**:

We don't need to re-run that migration again as the
renderer has been already removed in v9.

**missing-injectable**:

This migration is exclusively concerned with undecorated
providers referenced in an `NgModule`. We should re-run
that migration again as we don't have proper backsliding
prevention for this yet. We can consider adding an error
in ngtsc for v10, or v11. In either way, we should re-run
the migration.

**dynamic-queries**:

We ran this one in v9 to reduce code complexity in projects. Instead
of explicitly passing `static: false`, not passing any object literal
has the same semantics. We don't need to re-run the migration again
since there is no good way to prevent backsliding and we cannot always
run this migration for future versions (as some apps might actually
intentionally use the explicit `static: false` option).

Paul Gschwendtner c6ecdc9a81 feat(core): undecorated-classes-with-decorated-fields migration should handle classes with lifecycle hooks (#36921)
As of v10, undecorated classes using Angular features are no longer
supported. In v10, we plan on removing the undecorated classes
compatibility code in ngtsc. This means that old patterns for
undecorated classes will result in compilation errors.

We had a migration for this in v9 already, but it looks like
the migration does not handle cases where classes uses lifecycle
hooks. This is handled in the ngtsc compatibility code, and we
should handle it similarly in migrations too.

This has not been outlined in the migration plan initially,
but an appendix has been added for v10 to the plan document.

https://hackmd.io/vuQfavzfRG6KUCtU7oK_EA?both.

Note: The migration is unable to determine whether a given undecorated
class that only defines `ngOnDestroy` is a directive or an actual
service. This means that in some cases the migration cannot do
more than adding a TODO and printing an failure.

Certainly there are more ways to determine the type of such classes,
but it would involve metadata and NgModule analysis. This is out of
scope for this migration.

Paul Gschwendtner 9bde1be5a4 test: disable ng_package tests in ivy test jobs (#36944)
Since we no longer hardcode the `package.json` for
entry-points, a bug has appeared for `ng_package` in Ivy.

The `package.json` files are populated incorrectly with Ivy
as the flat module bundle name is not propagated from `ng_module`
to the `ng_package` rule. The rule then guesses the index file
to `index.js` and does not respect the flat module bundle shim.

Paul Gschwendtner c98a4d6ddd feat(ngcc): support for new APF where `module` points to esm2015 output (#36944)
As of version 10, libraries following the APF will no longer contain
ESM5 output. Hence, tests in ngcc need to be updated as they currently
rely on the release output of `@angular/core`.

Additionally, we'd need to support in ngcc that the `module`
property of entry-points no longer necessarily refers to
`esm5` output, but instead can also target `esm2015`.

We currently achieve this by checking the path the `module`
property points to. We can do this because as per APF, the
folder name is known for the esm2015 output. Long-term for
more coverage, we want to sniff the format by looking for
known ES2015 constructs in the file `module` refers to.

Paul Gschwendtner d5293d2aa3 fix(bazel): ng_package rule should update "package.json" of ts_library targets (#36944)
In the past we added support for `ts_library` to `ng_package`. For those
targets we never can determine the "index" file. Unlike `ng_module`,
there is no provider data for flat module bundles, so the `ng_package`
rule assumes that the index file is simply called `index`.

This works as expected, but we also added logic in the past that doesn't
allow `ng_package` to add format properties (e.g. `main`, `module`) to a
`package.json` if a package json is handwritten for such a `ts_library` target.

This has been done that way because we assumed that such `package.json` files
might want to set format properties explicitly to different paths due to a
faulty "index" guess.

We want to change this behavior as most of the time a `package.json`
file already exists with just the module name. In those cases, the
packager should still set the format properties. We should only warn
and skip automatic insertion of the format properties if such a
`package.json` explicitly sets format properties.

Igor Minar 9dbb30f884 feat(bazel): simplify ng_package by dropping esm5 and fesm5 (#36944)
esm5 and fesm5 are no longer needed and have been deprecated in the past.

https://v9.angular.io/guide/deprecations#esm5-and-fesm5-code-formats-in-angular-npm-packages

This commit modifies ng_package to no longer distribute these two formats in npm packages
built by ng_package (e.g. @angular/core).

This commit intentionally doesn't fully clean up the ng_package rule to remove all traces of esm5 and fems5
build artifacts as that is a bigger cleanup and currently we are narrowing down the scope of this change
to the MVP needed for v10, which in this case is 'do not put esm5 and fesm5' into the npm packages.

More cleanup to follow: https://angular-team.atlassian.net/browse/FW-2143

BREAKING CHANGE: esm5 and fesm5 format is no longer distributed in
Angular's npm packages e.g. @angular/core

If you are not using Angular CLI to build your application or library,
and you need to be able to build es5 artifacts, then you will need to
downlevel the distributed Angular code to es5 on your own.

Angular CLI will automatically downlevel the code to es5 if differential
loading is enabled in the Angular project, so no action is required from
Angular CLI users.

Pete Bacon Darwin fafa50d97f fix(ngcc): support ModuleWithProviders functions that delegate (#36948)
In #36892 the `ModuleWithProviders` type parameter becomes required.
This exposes a bug in ngcc, where it can only handle functions that have a
specific form:

```
function forRoot() {
  return { ... };
}
```

In other words, it only accepts functions that return an object literal.

In some libraries, the function instead returns a call to another function.
For example in `angular-in-memory-web-api`:

```
InMemoryWebApiModule.forFeature = function (dbCreator, options) {
  return InMemoryWebApiModule_1.forRoot(dbCreator, options);
};
```

This commit changes the parsing of such functions to use the
`PartialEvaluator`, which can evaluate these more complex function
bodies.

Pete Bacon Darwin e010f2ca54 refactor(ngcc): move `getModuleWithProvidersFunctions()` into the analyzer (#36948)
Previously this method was implemented on the `NgccReflectionHost`,
but really it is asking too much of the host, since it actually needs to do
some static evaluation of the code to be able to support a wider range
of function shapes. Also there was only one implementation of the method
in the `Esm2015ReflectionHost` since it has no format specific code in
in.

This commit moves the whole function (and supporting helpers) into the
`ModuleWithProvidersAnalyzer`, which is the only place it was being used.
This class will be able to do further static evaluation of the function bodies
in order to support more function shapes than the host can do on its own.

The commit removes a whole set of reflection host tests but these are
already covered by the tests of the analyzer.

Alex Rickabaugh ecffc3557f perf(compiler-cli): perform template type-checking incrementally (#36211)
This optimization builds on a lot of prior work to finally make type-
checking of templates incremental.

Incrementality requires two main components:
- the ability to reuse work from a prior compilation.
- the ability to know when changes in the current program invalidate that
  prior work.

Prior to this commit, on every type-checking pass the compiler would
generate new .ngtypecheck files for each original input file in the program.

1. (Build #1 main program): empty .ngtypecheck files generated for each
   original input file.

2. (Build #1 type-check program): .ngtypecheck contents overridden for those
   which have corresponding components that need type-checked.

3. (Build #2 main program): throw away old .ngtypecheck files and generate
   new empty ones.

4. (Build #2 type-check program): same as step 2.

With this commit, the `IncrementalDriver` now tracks template type-checking
_metadata_ for each input file. The metadata contains information about
source mappings for generated type-checking code, as well as some
diagnostics which were discovered at type-check analysis time. The actual
type-checking code is stored in the TypeScript AST for type-checking files,
which is now re-used between programs as follows:

1. (Build #1 main program): empty .ngtypecheck files generated for each
   original input file.

2. (Build #1 type-check program): .ngtypecheck contents overridden for those
   which have corresponding components that need type-checked, and the
   metadata registered in the `IncrementalDriver`.

3. (Build #2 main program): The `TypeCheckShimGenerator` now reuses _all_
   .ngtypecheck `ts.SourceFile` shims from build #1's type-check program in
   the construction of build #2's main program. Some of the contents of
   these files might be stale (if a component's template changed, for
   example), but wholesale reuse here prevents unnecessary changes in the
   contents of the program at this point and makes TypeScript's job a lot
   easier.

4. (Build #2 type-check program): For those input files which have not
   "logically changed" (meaning components within are semantically the same
   as they were before), the compiler will re-use the type-check file
   metadata from build #1, and _not_ generate a new .ngtypecheck shim.
   For components which have logically changed or where the previous
   .ngtypecheck contents cannot otherwise be reused, code generation happens
   as before.

Alex Rickabaugh b861e9c0ac perf(compiler-cli): split Ivy template type-checking into multiple files (#36211)
As a performance optimization, this commit splits the single
__ngtypecheck__.ts file which was previously added to the user's program as
a container for all template type-checking code into multiple .ngtypecheck
shim files, one for each original file in the user's program.

In larger applications, the generation, parsing, and checking of this single
type-checking file was a huge performance bottleneck, with the file often
exceeding 1 MB in text content. Particularly in incremental builds,
regenerating this single file for the entire application proved especially
expensive.

This commit introduces a new strategy for template type-checking code which
makes use of a new interface, the `TypeCheckingProgramStrategy`. This
interface abstracts the process of creating a new `ts.Program` to type-check
a particular compilation, and allows the mechanism there to be kept separate
from the more complex logic around dealing with multiple .ngtypecheck files.

A new `TemplateTypeChecker` hosts that logic and interacts with the
`TypeCheckingProgramStrategy` to actually generate and return diagnostics.
The `TypeCheckContext` class, previously the workhorse of template type-
checking, is now solely focused on collecting and generating type-checking
file contents.

A side effect of implementing the new `TypeCheckingProgramStrategy` in this
way is that the API is designed to be suitable for use by the Angular
Language Service as well. The LS also needs to type-check components, but
has its own method for constructing a `ts.Program` with type-checking code.

Note that this commit does not make the actual checking of templates at all
_incremental_ just yet. That will happen in a future commit.

Alex Rickabaugh 4213e8d5f0 fix(compiler): switch to 'referencedFiles' for shim generation (#36211)
Shim generation was built on a lie.

Shims are files added to the program which aren't original files authored by
the user, but files authored effectively by the compiler. These fall into
two categories: files which will be generated (like the .ngfactory shims we
generate for View Engine compatibility) as well as files used internally in
compilation (like the __ng_typecheck__.ts file).

Previously, shim generation was driven by the `rootFiles` passed to the
compiler as input. These are effectively the `files` listed in the
`tsconfig.json`. Each shim generator (e.g. the `FactoryGenerator`) would
examine the `rootFiles` and produce a list of shim file names which it would
be responsible for generating. These names would then be added to the
`rootFiles` when the program was created.

The fatal flaw here is that `rootFiles` does not always account for all of
the files in the program. In fact, it's quite rare that it does. Users don't
typically specify every file directly in `files`. Instead, they rely on
TypeScript, during program creation, starting with a few root files and
transitively discovering all of the files in the program.

This happens, however, during `ts.createProgram`, which is too late to add
new files to the `rootFiles` list.

As a result, shim generation was only including shims for files actually
listed in the `tsconfig.json` file, and not for the transitive set of files
in the user's program as it should.

This commit completely rewrites shim generation to use a different technique
for adding files to the program, inspired by View Engine's shim generator.
In this new technique, as the program is being created and `ts.SourceFile`s
are being requested from the `NgCompilerHost`, shims for those files are
generated and a reference to them is patched onto the original file's
`ts.SourceFile.referencedFiles`. This causes TS to think that the original
file references the shim, and causes the shim to be included in the program.
The original `referencedFiles` array is saved and restored after program
creation, hiding this little hack from the rest of the system.

The new shim generation engine differentiates between two kinds of shims:
top-level shims (such as the flat module entrypoint file and
__ng_typecheck__.ts) and per-file shims such as ngfactory or ngsummary
files. The former are included via `rootFiles` as before, the latter are
included via the `referencedFiles` of their corresponding original files.

As a result of this change, shims are now correctly generated for all files
in the program, not just the ones named in `tsconfig.json`.

A few mitigating factors prevented this bug from being realized until now:

* in g3, `files` does include the transitive closure of files in the program
* in CLI apps, shims are not really used

This change also makes use of a novel technique for associating information
with source files: the use of an `NgExtension` `Symbol` to patch the
information directly onto the AST object. This is used in several
circumstances:

* For shims, metadata about a `ts.SourceFile`'s status as a shim and its
  origins are held in the extension data.
* For original files, the original `referencedFiles` are stashed in the
  extension data for later restoration.

The main benefit of this technique is a lot less bookkeeping around `Map`s
of `ts.SourceFile`s to various kinds of data, which need to be tracked/
invalidated as part of incremental builds.

This technique is based on designs used internally in the TypeScript
compiler and is serving as a prototype of this design in ngtsc. If it works
well, it could have benefits across the rest of the compiler.

Alex Rickabaugh bab90a7709 fix(compiler-cli): fix bug tracking indirect NgModule dependencies (#36211)
The compiler needs to track the dependencies of a component, including any
NgModules which happen to be present in a component's scope. If an upstream
NgModule changes, any downstream components need to have their templates
re-compiled and re-typechecked.

Previously, the compiler handled this well for the A -> B -> C case where
module A imports module B which re-exports module C. However, it fell apart
in the A -> B -> C -> D case, because previously tracking focused on changes
to components/directives in the scope, and not NgModules specifically.

This commit introduces logic to track which NgModules contributed to a given
scope, and treat them as dependencies of any components within.

This logic also contains a bug, which is intentional for now. It
purposefully does not track transitive dependencies of the NgModules which
contribute to a scope. If it did, using the current dependency system, this
would treat all components and directives (even those not exported into the
scope) as dependencies, causing a major performance bottleneck. Only those
dependencies which contributed to the module's export scope should be
considered, but the current system is incapable of making this distinction.
This will be fixed at a later date.

Keen Yee Liau 58ea040570 test(language-service): add new mock host for testing ivy (#36879)
This commit adds a new mock host for testing the ivy language service.

Unlike the existing mock_host which mocks the LanguageServiceHost, the
Ivy mock host mocks just the filesystem interface, aka ts.ServerHost.

This is because Ivy language service requires an actual Project to
perform operations like adding synthetic typecheck files to the project,
and by extension, to the ts.Program. These requirements make the existing
mock host unsuitable to be reused.

This new testing structure also improves test performance, because the
old mock host copies (it actually creates symlinks, but still that's
relatively expensive due to the sheer number of files involved) all
@angular/* packages along with the typescript package to a temporary
node_modules directory. This is done every time setup() is called.
Instead, this new mock host just loads them from a pre-determined path
in Bazel runfiles.

Maximilian Koeller ee35e223a7 feat(service-worker): use `ignoreVary: true` when retrieving responses from cache (#34663)
The Angular ServiceWorker always uses a copy of the request without
headers for caching assets (in order to avoid issues with opaque
responses). Therefore, it was previously not possible to retrieve
resources from the cache if the response contained [Vary](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Vary) headers.

In addition to that, `Vary` headers do not work in all browsers (or work
differently) and may not work as intended with ServiceWorker caches. See
[this article](https://www.smashingmagazine.com/2017/11/understanding-vary-header) and the linked resources for more info.

This commit avoids the aforementioned issues by making sure the Angular
ServiceWorker always sets the `ignoreVary` option passed to
[Cache#match()](https://developer.mozilla.org/en-US/docs/Web/API/Cache/match) to `true`. This allows the ServiceWorker to correctly
retrieve cached responses with `Vary` headers, which was previously not
possible.

Fixes #36638

BREAKING CHANGE:

Previously, [Vary](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Vary)
headers would be taken into account when retrieving resources from the
cache, completely preventing the retrieval of cached assets (due to
ServiceWorker implementation details) and leading to unpredictable
behavior due to inconsistent/buggy implementations in different
browsers.

Now, `Vary` headers are ignored when retrieving resources from the
ServiceWorker caches, which can result in resources being retrieved even
when their headers are different. If your application needs to
differentiate its responses based on request headers, please make sure
the Angular ServiceWorker is [configured](https://angular.io/guide/service-worker-config)
to avoid caching the affected resources.

George Kalpakas 4779c4b94a fix(ngcc): handle `ENOMEM` errors in worker processes (#36626)
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).

George Kalpakas 966598cda7 fix(ngcc): support recovering when a worker process crashes (#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

Pete Bacon Darwin 70dd27ffd8 fix(compiler): normalize line endings in ICU expansions (#36741)
The html parser already normalizes line endings (converting `\r\n` to `\n`)
for most text in templates but it was missing the expressions of ICU expansions.

In ViewEngine backticked literal strings, used to define inline templates,
were already normalized by the TypeScript parser.
In Ivy we are parsing the raw text of the source file directly so the line
endings need to be manually normalized.

This change ensures that inline templates have the line endings of ICU
expression normalized correctly, which matches the ViewEngine.

In ViewEngine external templates, defined in HTML files, the behavior was
different, since TypeScript was not normalizing the line endings.
Specifically, ICU expansion "expressions" are not being normalized.
This is a problem because it means that i18n message ids can be different on
different machines that are setup with different line ending handling,
or if the developer moves a template from inline to external or vice versa.

The goal is always to normalize line endings, whether inline or external.
But this would be a breaking change since it would change i18n message ids
that have been previously computed. Therefore this commit aligns the ivy
template parsing to have the same "buggy" behavior for external templates.

There is now a compiler option `i18nNormalizeLineEndingsInICUs`, which
if set to `true` will ensure the correct non-buggy behavior. For the time
being this option defaults to `false` to ensure backward compatibility while
allowing opt-in to the desired behavior. This option's default will be
flipped in a future breaking change release.

Further, when this option is set to `false`, any ICU expression tokens,
which have not been normalized, are added to the `ParseResult` from the
`HtmlParser.parse()` method. In the future, this collection of tokens could
be used to diagnose and encourage developers to migrate their i18n message
ids. See FW-2106.

Pete Bacon Darwin 0c2ed4c3e5 fix(ngcc): do not use cached file-system (#36687)
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.

George Kalpakas 66effde9f3 fix(ngcc): do not spawn unlocker processes on cluster workers (#36569)
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.

George Kalpakas 6ab43d7335 fix(ngcc): correctly detect external files from nested `node_modules/` (#36559)
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/`.

JoostK 4aa4e6fd03 fix(compiler): handle type references to namespaced symbols correctly (#36106)
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.

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
`I18nOptions` in
@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.

Pete Bacon Darwin e526f74dfd refactor(compiler): create a new root `BindingScope` for each template (#36362)
Previously we had a singleton `ROOT_SCOPE` object, from
which all `BindingScope`s derived. But this caused ngcc to
produce non-deterministic output when running multiple workers
in parallel, since each process had its own `ROOT_SCOPE`.

In reality there is no need for `BindingScope` reference names
to be unique across an entire application (or in the case of ngcc
across all the libraries). Instead we just need uniqueness within
a template.

This commit changes the compiler to create a new root `BindingScope`
each time it compiles a component's template.

JiaLiPassion 4374931b0e fix(zone.js): zone.js patch jest should handle done correctly (#36022)
`zone.js` supports jest `test.each()` methods, but it
introduces a bug, which is the `done()` function will not be handled correctly.

```
it('should work with done', done => {
  // done will be undefined.
});
```

The reason is the logic of monkey patching `test` method is different from `jasmine` patch

// jasmine patch
```
return testBody.length === 0
   ? () => testProxyZone.run(testBody, null)
   : done => testProxyZone.run(testBody, null, [done]);
```

// jest patch
```
 return function(...args) {
   return testProxyZone.run(testBody, null, args);
 };
```

the purpose of this change is to handle the following cases.

```
test.each([1, 2])('test.each', (arg1, arg2) => {
  expect(arg1).toBe(1);
  expect(arg2).toBe(2);
});
```

so in jest, it is a little complex, because the `testBody`'s parameter may be bigger than 1, so the
logic in `jasmine`

```
return testBody.length === 0
   ? () => testProxyZone.run(testBody, null)
   : done => testProxyZone.run(testBody, null, [done]);
```
will not work for `test.each` in jest.

So in this PR, I created a dynamic `Function` to return the correct length of paramters (which is required by jest core), to handle
1. normal `test` with or without `done`.
2. each with parameters with or without done.

crisbeto 95fc3d4c5c fix(core): ngOnDestroy on multi providers called with incorrect context (#35840)
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).

George Kalpakas 5fa7b8ba56 fix(ngcc): detect non-emitted, non-imported TypeScript helpers (#36418)
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.

Paul Gschwendtner d43c30688a fix(core): avoid migration error when non-existent symbol is imported (#36367)
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.

George Kalpakas ca25c957bf fix(ngcc): correctly detect imported TypeScript helpers (#36284)
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).

George Kalpakas 93f07aee6c test(ngcc): use `DelegatingReflectionHost` for testing `NgccReflectionHost`s (#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.
These failures demonstrate pre-existing bugs in ngcc, that were hidden
due to the tests' being inconsistent with how the `ReflectionHost`s are
used in the actual program. They will be fixed in the next commit.

Paul Gschwendtner 32eafef6a7 fix(core): undecorated-classes-with-decorated-fields migration does not decorate derived classes (#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).

Fixes #34376.

JoostK 75afd80ae8 refactor(compiler): add `@nocollapse` annotation using a synthetic comment (#35932)
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
released with TypeScript 2.8.

This change is required for running ngtsc as TypeScript plugin in
Bazel's `ts_library` rule, to move away from the custom `ngc_wrapped`
approach.

George Kalpakas 326240eb91 fix(ngcc): allow ngcc configuration to match pre-release versions of packages (#36370)
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.

Keen Yee Liau 5516802142 fix(compiler): avoid undefined expressions in holey array (#36343)
From G3 bug ID: 116443331

The View Engine compiler crashes when it tries to compile a test in JIT mode
that includes the d3-scale-chromatic library [1]. The d3 package initializes
some arrays using the following pattern:

```js
export var scheme = new Array(3).concat(
  "d8b365f5f5f55ab4ac",
  // ... more entries
).map(colors);
```

The stack trace from the crash is as follows:

```
TypeError: Cannot read property 'visitExpression' of undefined

```

This is because the corresponding output AST for the array is of the form

```ts
[
  undefined,
  undefined,
  undefined,
  o.LiteralExpr,
  // ...
]
```

The output AST is clearly malformed and breaks the type representation of
`LiteralArrayExpr` in which every entry is expected to be of type `Expression`.

This commit fixes the bug by using a plain `for` loop to iterate over the
entire length of the holey array and convert undefined elements to
`LiteralExpr`.

### New stuff

* The `ts_project` rule is a simple wrapper around the TypeScript compiler, `tsc`. This is an alternative to `ts_library` but not a replacement. Read more about the trade-offs at https://bazelbuild.github.io/rules_nodejs/TypeScript#alternatives or read the [API docs](https://bazelbuild.github.io/rules_nodejs/TypeScript#ts_project)
* `pkg_npm` can now be used as a dependency within your repo as well as for publishing to npm. It provides a `LinkablePackageInfo` which is our internal API to pass package name/path to downstream compilations, essentially providing the "Lerna" feature.
* There is experimental support for Bazel's "worker mode" in `rollup_bundle`, which essentially puts Rollup in watch mode. Add the `supports_workers = True` attribute to opt-in.
* Better support for [pre-defined label variables](https://docs.bazel.build/versions/master/be/make-variables.html#predefined_label_variables) like `$(rootpath)` and `$(execpath)` - we no longer recommend using `$(location)` at all.

George Kalpakas 5cee709266 fix(ngcc): do not spawn more processes than intended in parallel mode (#36280)
When running in parallel mode, ngcc spawns multiple worker processed to
process the various entry-points. The number of max allowed processes is
determined by the number of CPU cores available to the OS. There is also
currently an [upper limit of 8][1]. The number of active workers is in
turn inferred by the number of [task assignments][2].

In the past, counting the entries of `ClusterMaster#taskAssignments` was
enough, because worker processes were spawned eagerly at the beginning
and corresponding entries were created in `taskAssignments`.
Since #35719 however, worker processes are spawned lazily on an as
needed basis. Because there is some delay between
[spawning a process][3] and [inserting it][4] into `taskAssignments`,
there is a short period of time when `taskAssignment.size` does not
actually represent the number of spawned processes. This can result in
spawning more than `ClusterMaster#workerCount` processes.

An example of this can be seen in #36278, where the debug logs indicate
9 worker processes had been spawned (`All 9 workers are currently busy`)
despite the hard limit of 8.

This commit fixes this by using `cluster.workers` to compute the number
of spawned worker processes. `cluster.workers` is updated synchronously
with `cluster.fork()` and thus reflects the number of spawned workers
accurately at all times.

Pete Bacon Darwin 995cd15a69 fix(ngcc): correctly identify the package path of secondary entry-points (#36249)
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`.

Paul Gschwendtner 44acf6734b build: allow custom module resolution for ts-circular-deps tests (#36226)
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.
