George Kalpakas 4c63241b34 fix(ngcc): do not run in parallel mode if there are less than 3 CPU cores (#36626)
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
there would only be one worker process (since one CPU core is always
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.

This commit fixes this by only running in parallel mode if there are
more than 2 CPU cores (i.e. at least 2 worker processes).

George Kalpakas 9aa778e843 refactor(ngcc): move "Compiling" log message before starting work on a task (#36626)
Previously, the "Compiling <entryPoint>" log message was printed before
starting to analyze and transform files, but after creating the
`EntryPointBundle` (which includes creating the TS program).

Since creating the `EntryPointBundle` involves some work, it is more
accurate to move the log message before creating the bundle.

crisbeto 3d82aa781d fix(core): attempt to recover from user errors during creation (#36381)
If there's an error during the first creation pass of a `TView`, the data structure may be corrupted which will cause framework assertion failures downstream which can mask the user's error. These changes add a new flag to the `TView` that indicates whether the first creation pass was successful, and if it wasn't we try re-create the `TView`.

JoostK 89c589085d fix(ngcc): recognize enum declarations emitted in JavaScript (#36550)
An enum declaration in TypeScript code will be emitted into JavaScript
as a regular variable declaration, with the enum members being declared
inside an IIFE. For ngcc to support interpreting such variable
declarations as enum declarations with its members, ngcc needs to
recognize the enum declaration emit structure and extract all member
from the statements in the IIFE.

This commit extends the `ConcreteDeclaration` structure in the
`ReflectionHost` abstraction to be able to capture the enum members
on a variable declaration, as a substitute for the original
`ts.EnumDeclaration` as it existed in TypeScript code. The static
interpreter has been extended to handle the extracted enum members
as it would have done for `ts.EnumDeclaration`.

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.

The change in e041ac6f0d
to support sending unlocker process output to the main ngcc

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.

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/`.

Previously, even if an entry-point did not need to be processed,
ngcc would always parse the files of the entry-point to compute
its dependencies. This can take a lot of time for large node_modules.

Now these dependencies are cached in the entry-point manifest,
and read from there rather than computing them every time.

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.

Terence D. Honles 078b0be4dc fix(common): `locales/global/*.js` are not ES5 compliant (#36342)
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
`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.
