The change in e041ac6f0d
to support sending unlocker process output to the main ngcc
console output prevents messages require that the main process
relinquishes the event-loop to allow the `stdout.on()` handler to
run. This results in none of the messages being written when ngcc
is run in `--no-async` mode, and some messages failing to be
written if the main process is killed (e.g. ctrl-C).
It appears that the problem with Windows and detached processes
is known - see https://github.com/nodejs/node/issues/3596#issuecomment-250890218.
But in the meantime, this commit is a workaround, where non-Windows
`inherit` the main process `stdout` while on Windows it reverts
to the async handler approach, which is better than nothing.

Instead the logic was falling back to the default case of `AM`.
Now the logic has been updated so that it matches times that are within
a day period that spans midnight, so it will now render the correct

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.

It could happen that resolved base classes have no value declaration.

Currently the migration will throw in such situations because it assumes
that `ts.Symbol#valueDeclaration` is always present. This is not the

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/`.

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.

compliant `locales/global/*.js` and that fixes my issue. However, I am
not sure if @angular-devkit/build-angular should be modified to produce

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

```
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.

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.

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

In #36089, `DelegatingReflectionHost` was introduced, which delegates to

Both abstract classes would need to be migrated. Previously, the migration

also decorates `BaseClassTwo`.
This is necessary because the Angular Compiler requires `BaseClassTwo` to

`MyButton` in order to perform type checking. Technically, not decorating
`BaseClassTwo` does not break at runtime.

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.

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.

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:
```

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`.

Previously, a bad baseUrl or path mapping passed to an `EntryPointFinder`
could cause the original `sourceDirectory` to be superceded by a higher
directory. This could result in none of the sourceDirectory entry-points being
processed.
Now missing basePaths computed from path-mappings are discarded with
a warning. Further, if the `baseUrl` is the root directory then a warning is
given as this is most likely an error in the tsconfig.json.

Currently the language service only provides support for determining the
type of array-like members when the array-like object is an `Array`.
However, there are other kinds of array-like objects, including
`ReadonlyArray`s and `readonly`-property arrays. This commit adds
support for retrieving the element type of arbitrary array-like objects.

The previous optimizations in #35756 to the
`DirectoryWalkerEntryPointFinder` were over zealous
with regard to packages that have entry-points stored
in "container" directories in the package, where the
container directory was not an entry-point itself.
Now we will also walk such "container" folders as long
as they do not contain `.js` files, which we regard as an
indicator that the directory will not contain entry-points.

This commit simplifies the `DirectoryWalkerEntryPointFinder` inter-method

`Bluebird.each` and `Bluebird.mapSeries` will accept a callback with `value` parameter,
the `value` should be the item in the array, not array itself.
For example:
```
const arr = [1, 2];
Bluebird.each(arr, function(value, idx) {
console.log(`value: ${value}, idx: ${idx}`);
})
```
the output will be
```
value: 1, idx: 0
value: 2, idx: 1
```

Prior to this commit, the `packages/core/src/render3/interfaces/query.ts` file used to import `QueryList` using `../../linker`, which contains a lot of re-exports and as a result, this one import caused a lot of circular deps cycles reported by the tool that checks such deps. In other places in the code the `QueryList` is imported using more narrow import (`linker/query_list`), so this commit uses the same pattern. This change allowed to reduce the number of known cycles from 343 to 207, the golden file was updated accordingly.

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`.

Prior to this commit, Ivy TestBed was accessing locale ID before `APP_INITIALIZER` functions were called. This execution order is not consistent with the app bootstrap logic in `application_ref.ts`. This commit updates Ivy TestBed execution order to call initializers first (since they might affect `LOCALE_ID` token value) and accessing and setting locale ID after that.
Fixes#36230.

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 enhances the `registerWhenStable` registration strategy by
adding support for an optional `<timeout>` argument, which guarantees
that the ServiceWorker will be registered when the timeout expires, even
if the app has not stabilized yet.
For example, with `registerWhenStable:5000` the ServiceWorker will be
registered as soon as the app stabilizes or after 5 seconds if the app
has not stabilized by then.
