to be transitioned into the `exec` configuration, resulting in much larger

We must read `Symbol.species` safely because `this` may be anything. For instance, `this`
may be an object without a prototype (created through `Object.create(null)`); thus
`this.constructor` will be undefined. One of the use cases is SystemJS creating
prototype-less objects (modules) via `Object.create(null)`. The SystemJS creates an empty
object and copies promise properties into that object (within the `getOrCreateLoad`
function). The zone.js then checks if the resolved value has the `then` method and invokes
it with the `value` context. Otherwise, this will throw an error: `TypeError: Cannot read
properties of undefined (reading 'Symbol(Symbol.species)')`.

Before this change, the macrotask for `setInterval(callback, ms)` was no
longer tracked by `TaskTrackingZoneSpec` after the `callback` was
invoked for the first time. Now the periodic macrotask is tracked until
it is cancelled, e.g. `clearInterval(id)`.
BREAKING CHANGE: in TaskTrackingZoneSpec track a periodic task until it is cancelled
The breaking change is scoped only to the plugin
`zone.js/plugins/task-tracking`. If you used `TaskTrackingZoneSpec` and
checked the pending macroTasks e.g. using `(this.ngZone as any)._inner
._parent._properties.TaskTrackingZone.getTasksFor('macroTask')`, then
its behavior slightly changed for periodic macrotasks. For example,
previously the `setInterval` macrotask was no longer tracked after its
callback was executed for the first time. Now it's tracked until
the task is explicitly cancelled, e.g with `clearInterval(id)`.

The Bazel NodeJS rules provide two ways of accessing node modules:
* A linker which creates a `node_modules` directory in the execroot/or in the runfiles.
* A patched module resolution where no node modules directory necessarily needs to exist.
The first is the default in `rules_nodejs` and the second is technically the most idiomatic
resolution mechanism in Bazel (as it matches with a runfile resolution library).
The linker is prone to race conditions in persistent workers, or non-sandbox environments (like
windows). This is because the linker for all workers will operate on a shared `execroot` directory
and the same `node_modules` directory is modified all the time / potentially conflicting with other
linker processes from other concurrently-running workers.
We rely on the patched module resolution anyway, but just need to disable the unused linker to avoid
issues like the following:

In early versions of Angular, it was sometimes necessary to provide a
`moduleId` to `@Component` metadata, and the common pattern for doing this
was to set `moduleId: module.id`. This relied on the bundler to fill in a
value for `module.id`.
However, due to the superficial similarity between `Component.moduleId` and
`NgModule.id`, many users ended up setting `id: module.id` in their
NgModules. This is an anti-pattern that has a few negative effects,
including preventing the NgModule from tree-shaking properly.
This commit changes the compiler to ignore `id: module.id` in NgModules, and
instead provide a warning which suggests removing the line entirely.

Previously, the `TraitCompiler` would naively consider a compilation as
failed if either analysis or resolution produced any diagnostics. This
commit adjusts the logic to only consider error diagnostics, which allows
warnings to be produced from `DecoratorHandler`s.
This is a precursor commit to introducing such a warning. As such, the
logic here will be tested in the next commit.

Angular contains an NgModule registry, which allows a user to declare
NgModules with string ids and retrieve them via those ids, using the
`getNgModuleById` API.
Previously, we attempted to structure this registration in a clever fashion
to allow for tree-shaking of registered NgModules (that is, those with ids).
This sort of worked due to the accidental alignment of behaviors from the
different tree-shakers involved. However, this trick relies on the
generation of `.ngfactory` files and how they're specifically processed in
various bundling scenarios. We intend to remove `.ngfactory` files, hence
we can no longer rely on them in this way.
The correct solution here is to recognize that `@NgModule({id})` is
inherently declaring a global side-effect, and such classes should not
really be eligible for tree-shaking in the first place. This commit removes
all the old registration machinery, and standardizes on generating a side-
effectful call to `registerNgModuleType` for NgModules that have ids.
There is some risk here that NgModules with unnecessary `id`s may not
tree-shake as a result of this change, whereas they would have in previous
circumstances. The fix here should be to remove the `id` if it's not needed.
Specifying an `id` is a request that the NgModule be retained regardless of
any other references, in case it is later looked up by string id.
PR Close#45024
When `@angular/compiler` processes metadata and compiles a definition field,
it might also choose to return statements that are associated with that
definition, and should be included after the type being compiled. Currently,
the linker ignores these statements, as there are none generated that are
relevant in the linking operation.
A challenge to supporting such associated statements is that the linker
operates on "declare" expressions, and replaces those expressions with other
expressions. It does not have the capability to append statements after the
whole type. The linker actually faces this challenge with statements from
the `ConstantPool` as well, and solves this problem by generating an IIFE
expression that executes the statements and then returns the definition
expression.
Previously, an `EmitScope` processed the definition and converted it to an
expression, as well as collected constant statements from a `ConstantPool`.
A special `IifeEmitScope` implementation was used when emitting into a
context where top-level constant statements couldn't be added at all, and
uses the IIFE strategy in this case.
This commit adds blanket support for associated statements to the linker
using this IIFE strategy. The main `EmitScope` now uses the IIFE strategy to
emit associated statements, and `IifeEmitScope` has been renamed to
`LocalEmitScope`. Now, the `LocalEmitScope` represents constant statements
as associated statements to the main `EmitScope` implementation, so they
get included in the IIFE as well.
Tests are adjusted/added to cover this new behavior. This is a refactoring
commit because no live generated code is affected - there are no cases where
associated statements are present in linked definitions today.
PR Close#45024
The `compileNgModule` operation previously supported a flag `emitInline`,
which controlled whether template scoping information for the NgModule was
emitted directly into the compiled NgModule definition, or whether an
associated statement was generated which patched the information onto the
NgModule definition. Both options are useful in different contexts.
This commit changes this flag to an enum (and renames it), which allows for
a third option - do not emit any template scoping information. This option
is added to better represent the actual behavior of the Angular Linker,
which sometimes configures `compileNgModule` to use the side-effectful
statement generation but which does not actually emit such associated
statements. In other words, the linker effectively does not generate
scoping information for NgModules at all (in some configurations) and this
option more directly expresses that behavior.
This is a refactoring as no generated code is changed as a result of
introducing this flag, due to the linker's behavior of not emitting
associated statements.

resolves#27577
PR Close#45212
The animations package supports adding default parameter values to an animation that will be used as a fallback if some parameters aren't defined. The problem is that they're applied using a spread expression which means that any own property of the animation parameters will override the defaults, even if it resolves to null or undefined. This can lead to obscure errors like "Cannot read property toString of undefined" for an animation that looks like `{params: {foo: undefined}}` with defaults `{foo: 123}`.
I ran into this issue while debugging some test failures on Material.
These changes address the issue by:
1. Applying the defaults if the resolved value is null or undefined.
2. Updating the validation function to use a null check instead of `hasOwnProperty`.

* `tree` function now accepts the old root rather than the old
`UrlTree`. The `urlTree` argument was only used to get the `root`.

This change now mirrors the argument order for `replaceSegment` and

* Extract `newRoot` to a variable. This just makes it more clear what's
going on at the end rather than combining a bunch of operations into
one.
These changes are being made so that hopefully a future refactor can be

`createUrlTree` function. These refactorings will make it easier to see
1:1 functionlity in these various places.

When parsing interpolations, the input string is _decoded_ from what was
in the orginal template. This means that we cannot soley rely on the input
string to compute source spans because it does not necessarily reflect
the exact content of the original template. Specifically, when there is
an HTML entity (i.e. ` `), this will show up in its decoded form
when processing the interpolation (' '). We need to compute offsets
using the original _encoded_ string.
Note that this problem only surfaces in the splitting of interpolations.
The spans to this point have already been tracked accurately. For
example, given the template ` <div></div>`, the source span for the
`div` is already correctly determined to be 6. Only when we encounter
interpolations with many parts do we run into situations where we need
to compute new spans for the individual parts of the interpolation.
