George Kalpakas 3e08347d8a ci(docs-infra): use the regular (non-Ivy) Angular packages in `test_docs_examples_ivy` CI job (#36015)
The docs examples tests are run both with Ivy turned off and on. When
Ivy is turned on, ngcc is used to convert all dependencies (including
the Angular framework packages to Ivy).

Previously, in order to speed things up, the `test_docs_examples_ivy` CI
job would use Angular packages built with Ivy (from
`dist/packages-dist-ivy-aot`). This however was a deviation from what
happens in real-world applications.

This commit changes the `test_docs_examples_ivy` CI job to always use
the regular Angular packages (as published on npm) and use ngcc to
convert them to Ivy.

JoostK 9e70bcb34f fix(ngcc): consistently delegate to TypeScript host for typing files (#36089)
When ngcc is compiling an entry-point, it uses a `ReflectionHost` that
is specific to its format, e.g. ES2015, ES5, UMD or CommonJS. During the
compilation of that entry-point however, the reflector may be used to
reflect into external libraries using their declaration files.

Up until now this was achieved by letting all `ReflectionHost` classes
consider their parent class for reflector queries, thereby ending up in
the `TypeScriptReflectionHost` that is a common base class for all
reflector hosts. This approach has proven to be prone to bugs, as
failing to call into the base class would cause incompatibilities with
reading from declaration files.

The observation can be made that there's only two distinct kinds of
reflection host queries:
1. the reflector query is about code that is part of the entry-point
   that is being compiled, or
2. the reflector query is for an external library that the entry-point
   depends on, in which case the information is reflected
   from the declaration files.

The `ReflectionHost` that was chosen for the entry-point should serve
only reflector queries for the first case, whereas a regular
`TypeScriptReflectionHost` should be used for the second case. This
avoids the problem where a format-specific `ReflectionHost` fails to
handle the second case correctly, as it isn't even considered for such
reflector queries.

This commit introduces a `ReflectionHost` that delegates to the
`TypeScriptReflectionHost` for AST nodes within declaration files,
otherwise delegating to the format-specific `ReflectionHost`.

Paul Gschwendtner a1e00f82f4 build: fix ts-api-guardian golden approval not working on windows (#36115)
Currently on Windows, it's not possible to approve goldens in
`ts-api-guardian`. This is because paths are resolved relatively
to the working directory. In Windows, golden files are resolved
to the actual workspace directory. The current logic tries to
compute a relative path to the runfile from the working directory.

This causes the file paths to have a lot of parent directory
path segments. Eventually, when joined with the build workspace
directory, the paths end up being incorrect. e.g.

```
fileName = ../../../../../../projects/angular/golden/<..>/common.d.ts`
outFile = BUILD_WORKSPACE_DIR + fileName;
```

To fix this, we no longer deal with confusing relative paths, but
instead always use absolute file system paths.

Additionally, this fixes that new goldens are generated at the wrong
location on all platforms.

Paul Gschwendtner b7138c1ec5 build: remove rollup packaging from dev-infra (#35647)
The dev-infra package currently uses rollup for packaging. This has been
done initially as a way to workaround manifest paths being used in the
AMD JavaScript output.

The actual solution to this problem is setting module names that match
the `package.json` name. This ensures that the package can be consumed
correctly in Bazel, and through NPM. This allows us to get rid of the
rollup bundling, and we don't need to hard-code which dependencies
should be external or included.

Additionally, tools that are part of `dev-infra` can now specify
their external dependencies simply in the `package.json`. To reduce
version duplication, and out-of-sync versions, a new genrule has been
created that syncs the versions with the top-level project
`package.json`.

Paul Gschwendtner 9ea53803f7 build: create tool for validating typescript circular dependencies (#35647)
Creates a tool for validating TypeScript circular dependencies. The tool
has been designed in a way that allows us to slowly burn down the amount
of circular dependencies while ensuring that we don't regress.

The tool doesn't rely on Madge since it doesn't provide a programmatic
way for doing path mapping. We need path mapping since we also want to
check for cycles across different entry-points or packages. The tool
uses the TypeScript AST to manually collect cycles. This code is not
a lot of bloat and also gives us more flexibility (if we ever need it).

Closes #35041.

Alex Rickabaugh e3ecdc6a63 feat(bazel): transform generated shims (in Ivy) with tsickle (#35975)
Currently, when Angular code is built with Bazel and with Ivy, generated
factory shims (.ngfactory files) are not processed via the majority of
tsickle's transforms. This is a subtle effect of the build infrastructure,
but it boils down to a TsickleHost method `shouldSkipTsickleProcessing`.

For ngc_wrapped builds (Bazel + Angular), this method is defined in the
`@bazel/typescript` (aka bazel rules_typescript) implementation of
`CompilerHost`. The default behavior is to skip tsickle processing for files
which are not present in the original `srcs[]` of the build rule. In
Angular's case, this includes all generated shim files.

For View Engine factories this is probably desirable as they're quite
complex and they've never been tested with tsickle. Ivy factories however
are smaller and very straightforward, and it makes sense to treat them like
any other output.

This commit adjusts two independent implementations of
`shouldSkipTsickleProcessing` to enable transformation of Ivy shims:

* in `@angular/bazel` aka ngc_wrapped, the upstream `@bazel/typescript`
  `CompilerHost` is patched to treat .ngfactory files the same as their
  original source file, with respect to tsickle processing.

  It is currently not possible to test this change as we don't have any test
  that inspects tsickle output with bazel. It will be extensively tested in
  g3.

* in `ngc`, Angular's own implementation is adjusted to allow for the
  processing of shims when compiling with Ivy. This enables a unit test to
  be written to validate the correct behavior of tsickle when given a host
  that's appropriately configured to process factory shims.

For ngtsc-as-a-plugin, a similar fix will need to be submitted upstream in
tsc_wrapped.

Andrew Kushnir 168a393589 refactor(core): misc refactoring to support upcoming changes to improve synthetic host bindings (#35884)
This commit performs a few updates to internal functions that would be required in upcoming changes to support synthetic host bindings in Directives.

* the `elementPropertyInternal` function was refactored to accept renderer as an argument (prior to that, there was a function that loads the renderer in some specific way for animation bindings)
* `elementPropertyInternal`, `elementAttributeInternal` and `listenerInternal` functions were updated to have a fixed set of arguments (for better performance)
* `elementPropertyInternal` and `elementAttributeInternal` functions were updated to take `tNode` as an argument instead of passing node index (that was used to retrieve `tNode` internally), in some cases we already have `tNode` available or we can retrieve it from the state

The refactoring was triggered by the need to pass different renderers to the `elementPropertyInternal` to support synthetic host bindings in Directives (see this comment for additional context: https://github.com/angular/angular/pull/35568/files#r388034584).

Alex Eagle 46fe8fb8b4 build: depend on bazelisk rather than directly on Bazel (#36078)
This has a couple benefits:
- we now use a .bazelversion file rather than package.json to pin the version of bazel we want. This means even if you install bazel on your computer rather than via yarn, you'll still get a warning if your bazel version is wrong.
- you no longer end up downloading three copies of bazel due to bugs in both npm and yarn where they download all tarballs before checking the metadata to see which are usable on the local platform.
- bazelisk correctly handles the tools/bazel trick for wrapping functionality, which we want to use to instrument developer build latencies

Ayaz Hafiz e179c5827f fix(compiler): do not recurse to find static symbols of same module (#35262)
To create the symbols of a module, the static symbol resolver first gets
all the symbols loaded in the module by an export statement. For `export
* from './module'`-like statements, all symbols from `./module` must be
loaded. In cases where the exporting module is actually the same module
that the export statement is in, this causes an unbounded recursive
resolution of the same module.

Exports of the same module are not needed, as their symbols will be
resolved when the symbols in the module metadata's `metadata` key is
explored.

This commit resolves the unbounded recursion by loading exporting
modules only if they differ from the module currently being resolved.

JiaLiPassion 8456c5ec60 feat(zone.js): add a zone config to allow user disable wrapping uncaught promise rejection (#35873)
Close #27840.

By default, `zone.js` wrap uncaught promise error and wrap it to a new Error object with some
additional information includes the value of the error and the stack trace.

Consider the following example:

```
Zone.current
  .fork({
    name: 'promise-error',
    onHandleError: (delegate: ZoneDelegate, current: Zone, target: Zone, error: any): boolean => {
      console.log('caught an error', error);
      delegate.handleError(target, error);
      return false;
    }
}).run(() => {
  const originalError = new Error('testError');
  Promise.reject(originalError);
});
```

The `promise-error` zone catches a wrapped `Error` object whose `rejection` property equals
to the original error, and the message will be `Uncaught (in promise): testError....`,
You can disable this wrapping behavior by defining a global configuraiton
`__zone_symbol__DISABLE_WRAPPING_UNCAUGHT_PROMISE_REJECTION = true;` before importing `zone.js`.

Andrew Kushnir 8c2d8428d5 fix(core): verify parsed ICU expression at runtime before executing it (#35923)
Prior to this commit, i18n runtime logic relied on the assumption that provided translation is syntactically correct, specifically around ICU syntax. However provided translations might contain some errors that lead to parsing failure. Specifically when translation contains curly braces, runtime i18n logic tries to parse them as an ICU expression and fails. This commit validates ICU parsing result (making sure it was parsed correctly) and throws an error if parsing error happens. The error that is thrown also contains translated message text for easier debugging.

Note: the check and the error message introduced in this PR is a safeguard against the problem that led to unhandled i18n runtime logic crash. So the framework behavior remains the same, we just improve the error message and it should be safe to merge to the patch branch.

Greg Magolan 2b6028b643 build: remove legacy integration test runner (#35985)
* integration tests target definitions in integration/BUILD.bazel updated to use a single dict
* payload tracking for integration tests updated to work under Bazel
* legacy integration_test CI job removed
* integration/run_tests.sh script no longer used in CI so it has been updated for running integration tests locally in the legacy way

JiaLiPassion 99ea5d7044 fix(zone.js): fix `zone-patch-rxjs` bundle to refer to `rxjs` (rather than include) it. (#35983)
Close #35878.

Before zone.js 0.10, the rollup config would refer to `rxjs` when bundling `zone-patch-rxjs.js`
From zone.js 0.10, we started to use bazel to build `zone-patch-rxjs.js` and the configuration was wrongly defined to include a copy of `rxjs` in the `zone-patch-rxjs.js`.

Pete Bacon Darwin 8ea61a19cd feat(ngcc): support invalidating the entry-point manifest (#35931)
In some scenarios it is useful for the developer to indicate
to ngcc that it should not use the entry-point manifest
file, and instead write a new one.

In the ngcc command line tool, this option is set by specfying

```
--invalidate-entry-point-manifest
```

Pete Bacon Darwin ec9f4d5bc6 perf(ngcc): use the `EntryPointManifest` in `DirectoryWalkerEntryPointFinder` (#35931)
The `DirectoryWalkerEntryPointFinder` has to traverse the
entire node_modules library everytime it executes in order to
identify the entry-points that need to be processed. This is
very time consuming (several seconds for big projects on
Windows).

This commit changes the `DirectoryWalkerEntryPointFinder` to
use the `EntryPointManifest` to store the paths to entry-points
that were found when doing this initial node_modules traversal
in a file to be reused for subsequent calls.

This dramatically speeds up ngcc processing when it has been run once
already.
