This commit will store a cached copy of the parsed tsconfig
that can be reused if the tsconfig path is the same.
This will improve the ngcc "noop" case, where there is no processing
to do, when the entry-points have already been processed.
Previously we were parsing this config every time we checked for
entry-points to process, which can take up to seconds in some
cases.

Resolves#36882
Previously, event listeners for component output events attached on an
Angular custom element before inserting it into the DOM (i.e. before
instantiating the underlying component) didn't fire for events emitted
during initialization lifecycle hooks, such as `ngAfterContentInit`,
`ngAfterViewInit`, `ngOnChanges` (initial call) and `ngOnInit`.
The reason was that that `NgElementImpl` [subscribed to events][1]
_after_ calling [ngElementStrategy#connect()][2], which is where the
[initial change detection][3] takes place (running the initialization
lifecycle hooks).
This commit fixes this by:
1. Ensuring `ComponentNgElementStrategy#events` is defined and available
for subscribing to, even before instantiating the component.
2. Ensuring `NgElementImpl` subscribes to `NgElementStrategy#events`
before calling `NgElementStrategy#connect()` (which initializes the
component instance).

Due to the desired patch branch (10.0.x) being on a semver version

The components repo and framework repository follow the same patch
branch concept. We should be able to share a script for determining
these merge branches.
Additonally the logic has been improved compared to the old merge script because
we no longer consult `git ls-remote` unless really needed. Currently,
`git ls-remote` is always consulted, even though not necessarily needed.
This can slow down the merge script and the caretaker process when a
couple of PRs are merged (personally saw around ~4 seconds per merge).
Additionally, the new logic is more strict and will ensure (in most
cases) that no wrong patch/minor branch is determined. Previously,
the script just used the lexicographically greatest patch branch.
This _could_ be wrong when a new patch branch has been created too
early, or by accident.

`ts-node` is now an optional peer dependency of the shared dev-infra
package. Whenever a `ng-dev` command runs, and a TypeScript-based
configuration file exists, `ts-node` is set up if available.
That allows consumers of the package (as the components repo) to more
conveniently use a TypeScript-based configuration for dev-infra.
Currently, commands would need to be proxied through `ts-node`
which rather complicates the setup:
```
NG_DEV_COMMAND="ts-node ./node_modules/@angular/dev-infra-private/cli.js"
```
I'm thinking that it should be best-practice to use TypeScript for
writing the configuration files. Given that the tool is used primarily
in Angular projects (for which most sources are TypeScript), this should
be acceptable.

As mentioned in the previous commit, the autosquash strategy has
not been used in the components repo, so we could easily regress.
After thorough manual testing of the autosquash strategy again,
now that the merge script will be moved to framework, it came
to mind that there is a bug with the base revision in the
autosquash merge strategy. The problem is that the base revision
of a given PR is relying on the amount of commits in a PR.
This is prone to error because the amount of commits could easily
change in the autosquash merge strategy, because fixup or squash
commits will be collapsed. Basically invalidating the base revision.
To fix this, we fixate the base revision by determining the actual
SHA. This one is guaranteed to not change after the autosquash rebase.
The current merge script in framework fixates the revision by creating
a separate branch, but there is no benefit in that, compared to just
using an explicit SHA that doesn't need to be cleaned up..
PR Close#37184
The components repo does not use the autosquash merge strategy, so
recent changes to that seem to broke the autosquash strategy.
Since we don't run the rebase in interactive mode, the `--autosquash`
flag has no effect. This is by design in Git. We can make it work by
setting the git sequence editor to `true` so that the rebase seems
like an interactive one to Git, while it isn't one for the user.
This matches conceptually with the merge script currently used in
framework. The only difference is that we allow a real interactive
rebase if the `commit message fixup` label is applied. This allows
commit message modifications (and others) if needed.

- Change the Node.js and `yarn` installation instructions to ensure the
`yarn` executable will be available on the `PATH` and not require an
interactive, login shell (as happens, for example, when installing it
via [nvm](https://github.com/nvm-sh/nvm)). This makes it easier to set

In order to avoid unnecessary operations, the `update-preview-server.sh`
script, that is used to update the PR preview server Docker container,
will only try to update the Docker container if either any files in the
`aio/aio-builds-setup/` directory have changed since the last update or
if a previous update failed. A failed previous update is detected by
checking whether the temporary `aio-builds:provisional` Docker image
still exists. This temporary image is created during the update
operation and is renamed to `aio-builds:latest` if the update goes well.
Previously, the update script was not able to detect a previous failed
attempt if the operation failed before creating the
`aio-builds:provisional` Docker image, such as if the `create-image.sh`
script failed. This could lead to a situation where the preview server
Docker container would not be updated after a failed attempt.
This commit improves the logic for detecting failed attempts to account
for this type of failures. It does this by not removing an older
`aio-builds:provisional` Docker image until a new one is successfully
created.
NOTE: While this is not full-proof, it is an improvement as it
eliminates a certain kind of failures.

As per our discussion in the dev-infra sync meeting, we don't want
to have all dependencies show up as peer dependencies. Instead, we
only want to have larger dependencies such as `typescript` or buildifier
as peer dependencies. Tslib is also included for the sake of it being
generally a peer dependency of all Angular framework packages.
The rationale is that Yarn is smart enough to collapse packages
if all satisfy a given range. This means that we don't necessarily
need to have all dependencies as peer dependencies. The initial
idea was to keep all dependencies as peer dependencies so that
we have control over duplication of packages as downloading multiple
packages w/ different versions impacts local dev, CI and caches.
At the same time though, we don't want to bother with setting
up peer dependencies all the time. Not every consumer of the
shared dev-infra package would like to manually specify `yaml`
or `multimatch` etc. in the project `package.json`. Hence we
decided to go with a hybrid approach where only more impactful
dependencies are peer dependencies, and other smaller ones can
be standard depdencies that are usually collapsed by Yarn anyway.
Also this commit removes tslib from build targets that don't
rely on it.

This exposes a bug in ngcc, where it can only handle functions that have a

```
function forRoot() {

In some libraries, the function instead returns a call to another function.

```
InMemoryWebApiModule.forFeature = function (dbCreator, options) {

Previously, in order to remain as deterministic as possible, the
Dockerfile for the preview server Docker image had all dependencies
pinned to specific versions. It turns out that some packages (such as

versions unavailable on the repositories once a newer version is
available.

- https://github.com/nodesource/distributions/issues/33

In order to ease local development, self-signed SSL/TLS certificates are
created when building the preview server Docker image. These
certificates are valid for 365 days. Thus, it is possible for an old
certificate to be re-used past its expiration date due to Docker's
caching intermediate layers.
Previously, this would lead to hard-to-debug failures in the
`aio-health-check` and `aio-verify-setup` checks. Even after finding out
that the failures were caused by an expired certificate, it was not
obvious why that would be the case.
This commit adds an additional check to the `aio-health-check` command
that checks the certificates' expiration dates. This helps surface such
errors. It also prints a more helpful message, prompting the user to
build the Docker image with the `--no-cache` option to fix the problem
with self-signed certificates.

Previously, in the `test_aio` CI job, we ran ngcc before building the
app with `yarn build`. This was supposed to have the benefit of taking
advantage of the parallel capabilities of standalone ngcc (vs implicitly
running it via `ng build`).
It turns out that the work done by the standalone ngcc was thrown away
before the `ng build`, resulting in `ng build` having to run ngcc all
over again. This happened because the `yarn build` script (run after the
standalone ngcc step) also runs `yarn install`, which essentially cleans
up `node_modules/`, thus discarding all the work already done by ngcc.
Here is an [example CI job][1], where this can be seen in action:
One can see the "Compiling <some-package> : es2015 as esm2015" logs in
the `yarn --cwd aio ngcc --properties es2015` step (as the standalone
ngcc processes the various entry-points) and then see the same logs in
the `yarn --cwd aio build --progress=false` step (as ngcc has to process
the entry-points all over again).
This commit removes the redundant standalone ngcc run and lets the CLI
handle ngcc via `ng build`. It is possible to instrument the build
process in a way that we can run the standalone ngcc after
`yarn install` and thus take advantage of the performance gains in
parallel mode, but the latest version of the CLI can already run ngcc in
parallel mode as a pre-build step, so this is unnecessary.

Only refresh transplanted views at the insertion location in Ivy.
Previously, Ivy would check transplanted views at both the insertion and

tree when we encounter a transplanted view that needs to be refreshed at
its declaration. We use this marker as an extra indication that we still
need to descend and refresh those transplanted views at their insertion
locations even if the insertion view and/or its parents are not dirty.
This change fixes several issues:
* Transplanted views refreshed twice if both insertion and declaration
are dirty. This could be an error if the insertion component changes
result in data not being available to the transplanted view because it
is slated to be removed.
* CheckAlways transplanted views not refreshed if shielded by

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).
PR Close#36626
Previously, when the last worker process crashed, the master process
would try to re-spawn it indefinitely. This could lead to an infinite
loop (if for some reason the worker process kept crashing).
This commit avoids this by limiting the number of re-spawn attempts to
3, after which ngcc will exit with an error.
PR Close#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

Previously, ngcc would run in parallel mode (using the
`ClusterExecutor`) when there were at least 2 CPU cores (and all other

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.

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`.

Currently, if changes are made to `compiler-cli/ngcc` and to other
compiler-related files, then only the `fw-ngcc` group is requested
for review. This is because the `not contains_any_globs` condition
will be false for `fw-compiler` and the group will never become active.
We fix this by removing the incorrect condition and filtering out ngcc
files before checking `contains_any_globs` in the primary fw-compiler
condition.

Currently, when verifying our pullapprove configuration, we don't
respect modifications to the set of files in a condition.
e.g. It's not possible to do the following:
```
contains_any_globs(files.exclude(...), [
```
This prevents us from having codeowner groups which match a directory,
but want to filter out specific sub directories. For example, `fw-core`
matches all files in the core package. We want to exclude the schematics
from that glob. Usually we do this by another exclude condition.
This has a *significant* downside though. It means that fw-core will not
be requested if a PR changes schematic code, _and_ actual fw-core code.
To support these conditions, the pullapprove verification tool is
refactored, so that it no longer uses Regular expressions for parsing,
but rather evaluates the code through a dynamic function. This is
possible since the conditions are written in simple Python that can
be run in NodeJS too (with small modifications/transformations).

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.

In the past, server-side rendered apps needed to convert URLs used in
API requests to absolute when rendering on the server. Originally, this
was handled in the `universal` guide and corresponding example app by
modifying the `HeroService` to use `APP_BASE_HREF` to derive the
absolute URL.
In #28956, the guide was updated to show an improved method: Specifying
an `HttpInterceptor` that took care of converting the URLs to absolute.
That interceptor was only provided when rendering the app on the server.
By mistake, the corresponding example app was not updated along with the
guide.

URLs to absolute inside the app. This is handled in the `@nguniversal`

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.)

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/`.

PR Close#36486
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

compliant `locales/global/*.js` and that fixes my issue. However, I am

Currently the golden output of the circular-deps tool is purely
based on the order of source files passed to the tool, and on the
amount of imports inside source files.
This is actually resulting in deterministic output as running
the tool multiple times without any changes to source files,
results in the same output.
Though it seems like the tool is too strict and we can avoid
unnecessary golden changes if:
1. A source file that is part of a cycle is imported earlier (in terms
of how the analyzer visits them). This could result in the cycle path
starting with a different source file.
2. Source files which are not part of a cycle are imported earlier
(in terms of how the analyzer visits them). This could result in moved
items in the golden if re-approved (even though the cycles remain the same)
To fix this, we normalize the cycle path array that serves as
serializable data structure for the text-based goldens. Since
the paths represents a cycle, the path can be shifted in a
deterministic way so that cycles don't change unnecessarily
in the golden, and to simplify comparison of cycles.
Additionally, we sort the cycles in a deterministic way so
that the golden doesn't change unnecessarily (as explained above).

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.

Each docs example has an `example-config.json` configuration file. Among
other things, this file can be used to specify what commands to run in
order to test the example. (If not specified, the `run-example-e2e.js`
script will run a default `yarn e2e` command.)
Previously, the property specifying the test commands was called `e2e`.
This is because in the past only e2e tests were run for docs examples.
Since recently, some examples may specify commands for other types of
tests (such as unit tests). Therefore, calling the property that holds
the list of test commands `e2e` no longer makes sense and can be
misleading to people looking at the configuration files.
This commit renamed the property to the more generic `tests`. In the
future, the `run-example-e2e.js` script (and corresponding npm script)
should be renamed and refactored to also avoid giving the impression
that only e2e tests are run.

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.

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

actual program. The changes in this commit are verified by ensuring the
failing tests are now passing (hence no new tests are added).

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.

The `undecorated-classes-with-decorated-fields` migration has been
introduced with 904a2018e0d3394ad91ffb6472f8271af7845295, but misses

```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).

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

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.

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.

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.

In #35381, a new Protractor config file was introduced in docs examples,
`protractor-puppeteer.conf.js`, that was only supposed to be used on CI
and not be shipped with the ZIP archives provided for users to download
and experiment with the docs examples locally.
The logic to ignore the `protractor-puppeteer.conf.js` file was
incorrect, resulting in the file being retained in some examples (e.g.
[universal][1]). The problem was not immediately obvious, because most
examples explicitly specify all `**/*.js` files as ignored, but for
other examples the file was retained in the ZIP archive.
This commit fixes the logic to ensure the file is excluded from all docs
examples ZIP archives.

The `removeSystemJsConfig` and `type` properties (present in some

- `removeSystemJsConfig` is no longer relevant since most examples have
been migrated to use the CLI.
- `type` is no longer relevant, because the project type is determined
based on the `projectType` property in `example-config.json` files.

`KeyValuePipe` currently accepts `null` values as well as `Map`s and a
few others. However, due to the way in which TS overloads work, a type
of `T|null` will not be accepted by `KeyValuePipe`'s signatures, even
though both `T` and `null` individually would be.
To make this work, each signature that accepts some type `T` has been
duplicated with a second one below it that accepts a `T|null` and
includes `null` in its return type.

Previously ngcc never preserved whitespaces but this is at odds
with how the ViewEngine compiler works. In ViewEngine, library
templates are recompiled with the current application's tsconfig
settings, which meant that whitespace preservation could be set
in the application tsconfig file.
This commit allows ngcc to use the `preserveWhitespaces` setting
from tsconfig when compiling library templates. One should be aware
that this disallows different projects with different tsconfig settings
to share the same node_modules folder, with regard to whitespace
preservation. But this is already the case in the current ngcc since
this configuration is hard coded right now.

This commit augments the `FactoryDef` declaration of Angular decorated
classes to contain information about the parameter decorators used in
the constructor. If no constructor is present, or none of the parameters
have any Angular decorators, then this will be represented using the
`null` type. Otherwise, a tuple type is used where the entry at index `i`
corresponds with parameter `i`. Each tuple entry can be one of two types:
1. If the associated parameter does not have any Angular decorators,
the tuple entry will be the `null` type.
2. Otherwise, a type literal is used that may declare at least one of
the following properties:
- "attribute": if `@Attribute` is present. The injected attribute's
name is used as string literal type, or the `unknown` type if the
attribute name is not a string literal.
- "self": if `@Self` is present, always of type `true`.
- "skipSelf": if `@SkipSelf` is present, always of type `true`.
- "host": if `@Host` is present, always of type `true`.
- "optional": if `@Optional` is present, always of type `true`.
A property is only present if the corresponding decorator is used.
Note that the `@Inject` decorator is currently not included, as it's
non-trivial to properly convert the token's value expression to a
type that is valid in a declaration file.
Additionally, the `ComponentDefWithMeta` declaration that is created for
Angular components has been extended to include all selectors on
`ng-content` elements within the component's template.
This additional metadata is useful for tooling such as the Angular
Language Service, as it provides the ability to offer suggestions for
directives/components defined in libraries. At the moment, such
tooling extracts the necessary information from the _metadata.json_
manifest file as generated by ngc, however this metadata representation
is being replaced by the information emitted into the declaration files.

Previously, when an input property was initially set to `undefined` it
would not be correctly recognized as a change (and trigger
`ngOnChanges()`).
This commit ensures that explicitly setting an input to `undefined` is
correctly handled the same as setting the property to any other value.
This aligns the behavior of Angular custom elements with that of the
corresponding components when used directly (not as custom elements).

Previously, when an input property was set on an `NgElement` before
instantiating the underlying component, the `SimpleChange` object passed

This commit fixes this by ensuring `SimpleChange#firstChange` is set to
true on first change, regardless if the property was set before or after
instantiating the component. This alignthe behavior of Angular custom
elements with that of the corresponding components when used directly

When computing the dependencies between packages which are not in
node_modules, we may need to rely upon path-mappings to find the path
to the imported entry-point.
This commit allows ngcc to use the path-mappings from a tsconfig
file to find dependencies. By default any tsconfig.json file in the directory
above the `basePath` is loaded but it is possible to use a path to a
specific file by providing the `tsConfigPath` property to mainNgcc,
or to turn off loading any tsconfig file by setting `tsConfigPath` to `null`.
At the command line this is controlled via the `--tsconfig` option.

If you are subject to or witness unacceptable behavior, or have any other concerns, please email us at [conduct@angular.io](mailto:conduct@angular.io).
We would love for you to contribute to Angular and help make it even better than it is today!
As a contributor, here are the guidelines we would like you to follow:
- [Code of Conduct](#coc)
- [Question or Problem?](#question)
- [Issues and Bugs](#issue)
- [Feature Requests](#feature)
- [Submission Guidelines](#submit)
- [Coding Rules](#rules)
- [Commit Message Guidelines](#commit)
- [Signing the CLA](#cla)
## <aname="coc"></a> Code of Conduct
Help us keep Angular open and inclusive.
Please read and follow our [Code of Conduct][coc].
## <aname="question"></a> Got a Question or Problem?
Do not open issues for general support questions as we want to keep GitHub issues for bug reports and feature requests.
Instead, we recommend using [Stack Overflow](https://stackoverflow.com/questions/tagged/angular) to ask support-related questions. When creating a new question on Stack Overflow, make sure to add the `angular` tag.
Stack Overflow is a much better place to ask questions since:
- there are thousands of people willing to help on Stack Overflow
- questions and answers stay available for public viewing so your question/answer might help someone else
- Stack Overflow's voting system assures that the best answers are prominently visible.
To save your and our time, we will systematically close all issues that are requests for general support and redirect people to Stack Overflow.
If you would like to chat about the question in real-time, you can reach out via [our gitter channel][gitter].
## <aname="issue"></a> Found a Bug?
If you find a bug in the source code, you can help us by [submitting an issue](#submit-issue) to our [GitHub Repository][github].
Even better, you can [submit a Pull Request](#submit-pr) with a fix.
## <aname="feature"></a> Missing a Feature?
You can *request* a new feature by [submitting an issue](#submit-issue) to our GitHub Repository.
If you would like to *implement* a new feature, please consider the size of the change in order to determine the right steps to proceed:
* For a **Major Feature**, first open an issue and outline your proposal so that it can be discussed.
This process allows us to better coordinate our efforts, prevent duplication of work, and help you to craft the change so that it is successfully accepted into the project.
**Note**: Adding a new topic to the documentation, or significantly re-writing a topic, counts as a major feature.
* **Small Features** can be crafted and directly [submitted as a Pull Request](#submit-pr).
## <aname="submit"></a> Submission Guidelines
### <aname="submit-issue"></a> Submitting an Issue
Before you submit an issue, please search the issue tracker, maybe an issue for your problem already exists and the discussion might inform you of workarounds readily available.
We want to fix all the issues as soon as possible, but before fixing a bug we need to reproduce and confirm it.
In order to reproduce bugs, we require that you provide a minimal reproduction.
Having a minimal reproducible scenario gives us a wealth of important information without going back and forth to you with additional questions.
A minimal reproduction allows us to quickly confirm a bug (or point out a coding problem) as well as confirm that we are fixing the right problem.
We require a minimal reproduction to save maintainers' time and ultimately be able to fix more bugs.
Often, developers find coding problems themselves while preparing a minimal reproduction.
We understand that sometimes it might be hard to extract essential bits of code from a larger codebase but we really need to isolate the problem before we can fix it.
Unfortunately, we are not able to investigate / fix bugs without a minimal reproduction, so if we don't hear back from you, we are going to close an issue that doesn't have enough info to be reproduced.
You can file new issues by selecting from our [new issue templates](https://github.com/angular/angular/issues/new/choose) and filling out the issue template.
### <aname="submit-pr"></a> Submitting a Pull Request (PR)
Before you submit your Pull Request (PR) consider the following guidelines:
1. Search [GitHub](https://github.com/angular/angular/pulls) for an open or closed PR that relates to your submission.
You don't want to duplicate existing efforts.
2. Be sure that an issue describes the problem you're fixing, or documents the design for the feature you'd like to add.
Discussing the design upfront helps to ensure that we're ready to accept your work.
The `<type>` and `<summary>` fields are mandatory, the `(<scope>)` field is optional.
##### Type
Must be one of the following:
* **build**: Changes that affect the build system or external dependencies (example scopes: gulp, broccoli, npm)
* **ci**: Changes to our CI configuration files and scripts (example scopes: Circle, BrowserStack, SauceLabs)
* **docs**: Documentation only changes
* **feat**: A new feature
* **fix**: A bug fix
* **perf**: A code change that improves performance
* **refactor**: A code change that neither fixes a bug nor adds a feature
* **style**: Changes that do not affect the meaning of the code (white-space, formatting, missing semi-colons, etc)
* **test**: Adding missing tests or correcting existing tests
##### Scope
The scope should be the name of the npm package affected (as perceived by the person reading the changelog generated from commit messages).
The following is the list of supported scopes:
* `animations`
* `bazel`
* `benchpress`
* `common`
* `compiler`
* `compiler-cli`
* `core`
* `elements`
* `forms`
* `http`
* `language-service`
* `localize`
* `platform-browser`
* `platform-browser-dynamic`
* `platform-server`
* `platform-webworker`
* `platform-webworker-dynamic`
* `router`
* `service-worker`
* `upgrade`
* `zone.js`
There are currently a few exceptions to the "use package name" rule:
* `packaging`: used for changes that change the npm package layout in all of our packages, e.g. public path changes, package.json changes done to all packages, d.ts file/format changes, changes to bundles, etc.
* `changelog`: used for updating the release notes in CHANGELOG.md
* `dev-infra`: used for dev-infra related changes within the directories /scripts, /tools and /dev-infra
* `docs-infra`: used for docs-app (angular.io) related changes within the /aio directory of the repo
* `migrations`: used for changes to the `ng update` migrations.
* `ngcc`: used for changes to the [Angular Compatibility Compiler](./packages/compiler-cli/ngcc/README.md)
* `ve`: used for changes specific to ViewEngine (legacy compiler/renderer).
* none/empty string: useful for `style`, `test` and `refactor` changes that are done across all packages (e.g. `style: add missing semicolons`) and for docs changes that are not related to a specific package (e.g. `docs: fix typo in tutorial`).
##### Summary
Use the summary field to provide a succinct description of the change:
* use the imperative, present tense: "change" not "changed" nor "changes"
* don't capitalize the first letter
* no dot (.) at the end
#### Commit Message Body
Just as in the summary, use the imperative, present tense: "fix" not "fixed" nor "fixes".
Explain the motivation for the change in the commit message body. This commit message should explain _why_ you are making the change.
You can include a comparison of the previous behavior with the new behavior in order to illustrate the impact of the change.
#### Commit Message Footer
The footer can contain information about breaking changes and is also the place to reference GitHub issues, Jira tickets, and other PRs that this commit closes or is related to.
```
BREAKING CHANGE: <breakingchangesummary>
<BLANKLINE>
<breakingchangedescription+migrationinstructions>
<BLANKLINE>
<BLANKLINE>
Fixes #<issuenumber>
```
Breaking Change section should start with the phrase "BREAKING CHANGE: " followed by a summary of the breaking change, a blank line, and a detailed description of the breaking change that also includes migration instructions.
### Revert commits
If the commit reverts a previous commit, it should begin with `revert: `, followed by the header of the reverted commit.
The content of the commit message body should contain:
- information about the SHA of the commit being reverted in the following format: `This reverts commit <SHA>`,
- a clear description of the reason for reverting the commit message.

¡Nos encantaría que contribuyeras a Angular y que ayudaras a hacerlo aún mejor de lo que es hoy!
Como colaborador, estos son los lineamientos que nos gustaría que siguieras:
We would love for you to contribute to Angular and help make it even better than it is
today! As a contributor, here are the guidelines we would like you to follow:

## <aname="coc"></a> Code of Conduct
Help us keep Angular open and inclusive. Please read and follow our [Code of Conduct][coc].
## <aname="question"></a> Got a Question or Problem?
Do not open issues for general support questions as we want to keep GitHub issues for bug reports and feature requests. You've got much better chances of getting your question answered on [Stack Overflow](https://stackoverflow.com/questions/tagged/angular) where the questions should be tagged with tag `angular`.
Stack Overflow is a much better place to ask questions since:
- there are thousands of people willing to help on Stack Overflow
- questions and answers stay available for public viewing so your question / answer might help someone else
- Stack Overflow's voting system assures that the best answers are prominently visible.
To save your and our time, we will systematically close all issues that are requests for general support and redirect people to Stack Overflow.
If you would like to chat about the question in real-time, you can reach out via [our gitter channel][gitter].
## <aname="issue"></a> Found a Bug?
If you find a bug in the source code, you can help us by
[submitting an issue](#submit-issue) to our [GitHub Repository][github]. Even better, you can
[submit a Pull Request](#submit-pr) with a fix.
## <aname="feature"></a> Missing a Feature?
You can *request* a new feature by [submitting an issue](#submit-issue) to our GitHub
Repository. If you would like to *implement* a new feature, please submit an issue with
a proposal for your work first, to be sure that we can use it.
Please consider what kind of change it is:
* For a **Major Feature**, first open an issue and outline your proposal so that it can be
discussed. This will also allow us to better coordinate our efforts, prevent duplication of work,
and help you to craft the change so that it is successfully accepted into the project.
* **Small Features** can be crafted and directly [submitted as a Pull Request](#submit-pr).
## <aname="submit"></a> Submission Guidelines
### <aname="submit-issue"></a> Submitting an Issue
Before you submit an issue, please search the issue tracker, maybe an issue for your problem already exists and the discussion might inform you of workarounds readily available.
We want to fix all the issues as soon as possible, but before fixing a bug we need to reproduce and confirm it. In order to reproduce bugs, we will systematically ask you to provide a minimal reproduction. Having a minimal reproducible scenario gives us a wealth of important information without going back & forth to you with additional questions.
A minimal reproduction allows us to quickly confirm a bug (or point out a coding problem) as well as confirm that we are fixing the right problem.
We will be insisting on a minimal reproduction scenario in order to save maintainers time and ultimately be able to fix more bugs. Interestingly, from our experience, users often find coding problems themselves while preparing a minimal reproduction. We understand that sometimes it might be hard to extract essential bits of code from a larger codebase but we really need to isolate the problem before we can fix it.
Unfortunately, we are not able to investigate / fix bugs without a minimal reproduction, so if we don't hear back from you, we are going to close an issue that doesn't have enough info to be reproduced.
You can file new issues by selecting from our [new issue templates](https://github.com/angular/angular/issues/new/choose) and filling out the issue template.
## <aname="coc"></a> Código de conducta
### <aname="submit-pr"></a> Submitting a Pull Request (PR)
Before you submit your Pull Request (PR) consider the following guidelines:
Ayúdanos a mantener Angular abierto e inclusivo.
Por favor lee y sigue nuestro [Código de conducta][coc].
## <aname="question"></a> ¿Tienes alguna pregunta o problema?
No abras *issues* para preguntas de soporte general ya que queremos mantener los *issues* de GitHub para reporte de *bugs* y solicitud de funcionalidades.
En su lugar, recomendamos utilizar [Stack Overflow](https://stackoverflow.com/questions/tagged/angular) para hacer preguntas relacionadas con soporte. Al crear una nueva pregunta en Stack Overflow, asegúrate de agregar el etiqueta (tag) de `angular`.
Stack Overflow es mucho mejor para hacer preguntas ya que:
- Hay miles de personas dispuestas a ayudar en preguntas y respuestas de Stack Overflow
que permanecen disponibles para el público, por lo que tu pregunta o respuesta podría ayudar a otra persona.
- El sistema de votación de Stack Overflow asegura que las mejores respuestas sobresalgan y sean visibles.
Para ahorrar tu tiempo y el nuestro, cerraremos sistemáticamente todos los *issues* que sean solicitudes de soporte general y redirigiremos a las personas a Stack Overflow.
Si deseas chatear sobre alguna pregunta en tiempo real, puedes hacerlo a través de nuestro [canal de Gitter][gitter].
## <aname="issue"></a> ¿Encontraste un Bug?
Si encontraste un error en el código fuente, puedes ayudarnos [creando un *issue*](#submit-issue) en nuestro [repositorio de GitHub][github].
O incluso mejor, puedes [crear un *Pull Request*](#submit-pr) con la solución.
Puedes solicitar una nueva funcionalidad [creando un *issue*](#submit-issue) en nuestro repositorio de GitHub.
Si deseas implementar una nueva funcionalidad, por favor considera el tamaño del cambio para determinar los pasos correctos para continuar:
* Para un **cambio significativo**, primero abre un *issue* y describe tu propuesta para que pueda ser discutida.
Este proceso nos permite coordinar mejor nuestros esfuerzos, evitar trabajo duplicado y ayudarte a diseñar el cambio para que sea aceptado con éxito en el proyecto.
**Nota**: Agregar un nuevo tema a la documentación o reescribir significativamente un tema, también cuenta como *cambio significativo*.
* **Cambios pequeños** pueden ser elaborados y directamente [creados como un _pull request_](#submit-pr).
## <aname="submit"></a> Guía para la creación de issues y PRs
### <aname="submit-issue"></a> Creación de _issues_
Antes de crear un *issue*, por favor busca en el el *issue tracker*, quizá un *issue* para tu problema ya existe y la discusión puede informarte sobre soluciones alternativas disponibles.
Queremos solucionar todos los problemas lo antes posible, pero antes de corregir un bug necesitamos reproducirlo y confirmarlo.
Para reproducir errores, requerimos que proporciones una reproducción mínima.
Tener un escenario reproducible mínimo nos brinda una gran cantidad de información importante sin tener que ir y venir con preguntas adicionales.
Una reproducción mínima nos permite confirmar rápidamente un bug (o señalar un problema de código), así también confirmar que estamos solucionando el problema correcto.
Requerimos una reproducción mínima para ahorrar tiempo a los encargados del mantenimiento y en última instancia, poder corregir más bugs.
A menudo los desarrolladores encuentran problemas de código mientras preparan una reproducción mínima.
Entendemos que a veces puede ser difícil extraer porciones esenciales de código de un código más grande, pero realmente necesitamos aislar el problema antes de poder solucionarlo.
Desafortunadamente no podemos investigar/corregir errores sin una reproducción mínima, por lo que si no tenemos tu retroalimentación del bug, vamos a cerrar el *issue* ya que no tiene suficiente información para reproducirse.
Puedes presentar nuevos *issues* seleccionando nuestra [plantilla de _issues_](https://github.com/angular/angular/issues/new/choose) y complentando la plantilla.
### <aname="submit-pr"></a> Creación de un Pull Requests (PR)
Antes de crear tu Pull Request (PR) considera los siguientes lineamientos:
1. Busca en [GitHub](https://github.com/angular/angular/pulls) PRs que estén abiertos o cerrados y que estén relacionados con el que vas a crear.
No deseas duplicar los esfuerzos existentes.
2. Asegúrate de que el PR describa el problema que estás solucionando o que documente el diseño de la funcionalidad que deseas agregar.
Discutir el diseño por adelantado ayuda a garantizar que estemos listos para aceptar tu trabajo.
3. Por favor firma nuestro [Acuerdo de Licencia de Colaborador (CLA)](#cla) antes de crear PRs.
No podemos aceptar el código sin el Acuerdo de Licencia de Colaborador (CLA) firmado.
Asegúrate de crear todas las contribuciones de Git con la dirección de correo electrónico asociada con tu firma del Acuerdo de Licencia de Colaborador (CLA).
4. Haz *fork* del repositorio angular/angular.
5. Haz tus cambios en una nueva rama de Git:
1. Search [GitHub](https://github.com/angular/angular/pulls) for an open or closed PR
that relates to your submission. You don't want to duplicate effort.
1. Be sure that an issue describes the problem you're fixing, or documents the design for the feature you'd like to add.
Discussing the design up front helps to ensure that we're ready to accept your work.
We cannot accept code without this. Make sure you sign with the primary email address of the Git identity that has been granted access to the Angular repository.
1. Fork the angular/angular repo.
1. Make your changes in a new git branch:
```shell
git checkout -b my-fix-branch master
```
6. Crea tu correción, **incluyendo casos de prueba apropiados**.
7. Sigue nuestras [Reglas de código](#rules).
8. Ejecuta todo el conjunto de pruebas de Angular, tal como está descrito en la [documentación del desarrollador][dev-doc], y asegúrate de que todas las pruebas pasen.
9. Crea un commit de tus cambios utilizando un mensaje de commit descriptivo que siga nuestra [convención para el mensaje de los commits](#commit).
Es necesario cumplir con estas convenciones porque las notas de las versiones se generan automáticamente a partir de estos mensajes.
1. Create your patch, **including appropriate test cases**.
1. Follow our [Coding Rules](#rules).
1. Run the full Angular test suite, as described in the [developer documentation][dev-doc],
and ensure that all tests pass.
1. Commit your changes using a descriptive commit message that follows our
[commit message conventions](#commit). Adherence to these conventions
is necessary because release notes are automatically generated from these messages.
```shell
git commit -a
```
Nota: la opción de la línea de comandos de Git `-a` automaticamente hará "add" y "rm" a los archivos editados.
Note: the optional commit `-a` command line option will automatically "add" and "rm" edited files.
10. Haz push de tu rama a GitHub:
1. Push your branch to GitHub:
```shell
git push origin my-fix-branch
```
11. En GitHub, crea un pull request a `angular:master`.
1. In GitHub, send a pull request to `angular:master`.
* If we suggest changes then:
* Make the required updates.
* Re-run the Angular test suites to ensure tests are still passing.
* Rebase your branch and force push to your GitHub repository (this will update your Pull Request):
Si solicitamos cambios a través de revisiones de código, sigue las siguientes indicaciones:
```shell
git rebase master -i
git push -f
```
* Haz los cambios requeridos.
* Ejecuta nuevamente el conjunto de pruebas de Angular para asegurar que todas las pruebas aún están pasando.
* Haz rebase de tu rama a la rama master y haz push con la opción `-f` a tu repositorio de Github (esto actualizará tu Pull Request):
That's it! Thank you for your contribution!
```shell
git rebase master -i
git push -f
```
#### After your pull request is merged
¡Es todo! ¡Muchas gracias por tu contribución!
After your pull request is merged, you can safely delete your branch and pull the changes
from the main (upstream) repository:
#### Después del merge de tu pull request
Después de que se hizo merge de tu pull request, puedes eliminar de forma segura tu rama y hacer pull de los cambios del repositorio principal (upstream):
* Elimina la rama remota en GitHub a través de la interfaz de usuario web de GitHub o en tu línea de comandos de la siguiente manera:
* Delete the remote branch on GitHub either through the GitHub web UI or your local shell as follows:
```shell
git push origin --delete my-fix-branch
```
* Muévete a la rama master:
* Check out the master branch:
```shell
git checkout master -f
```
* Elimina tu rama local:
* Delete the local branch:
```shell
git branch -D my-fix-branch
```
* Actualiza tu rama master con la última versión del fork (upstream):
* Update your master with the latest upstream version:
```shell
git pull --ff upstream master
```
## <aname="rules"></a> Coding Rules
To ensure consistency throughout the source code, keep these rules in mind as you are working:
## <aname="rules"></a> Reglas del código
Para garantizar la coherencia en todo el código fuente, ten en cuenta estas reglas mientras trabajas:
* All features or bug fixes **must be tested** by one or more specs (unit-tests).
* All public API methods **must be documented**. (Details TBC).
* We follow [Google's JavaScript Style Guide][js-style-guide], but wrap all code at
**100 characters**. An automated formatter is available, see
[DEVELOPER.md](docs/DEVELOPER.md#clang-format).
* Todas las funcionalidades o solución de bugs **deben ser probadas** por una o más pruebas (pruebas unitarias).
* Todos los métodos públicos del API **deben ser documentados**.
* Seguimos la [guía de estilo JavaScript de Google][js-style-guide], pero cada línea no debe exceder **100 caracteres**.
## <aname="commit"></a> Commit Message Guidelines
Un formateador automatizado está disponible, revisar [DEVELOPER.md](docs/DEVELOPER.md#clang-format).
## <aname="commit"></a> Formato para el mensaje de los commits
*Esta especificación está inspirada y reemplaza el [Formato de mensaje de commits de AngularJS][commit-message-format].*
Tenemos reglas muy precisas sobre cómo deben formatearse nuestros mensajes de los commits de Git.
Este formato permite tener **un historial de commits más facil de leer**.
Cada mensaje de un commit consta del **header**, el **body**, y el **footer**.
We have very precise rules over how our git commit messages can be formatted. This leads to **more
readable messages** that are easy to follow when looking through the **project history**. But also,
we use the git commit messages to **generate the Angular change log**.
### Commit Message Format
Each commit message consists of a **header**, a **body** and a **footer**. The header has a special
format that includes a **type**, a **scope** and a **subject**:
```
<header>
<LINEA VACIA>
<type>(<scope>): <subject>
<BLANKLINE>
<body>
<LINEA VACIA>
<BLANK LINE>
<footer>
```
El `header` es obligatorio y debe ajustarse al formato del [mensaje del header del commit](#commit-header).
The **header** is mandatory and the **scope** of the header is optional.
El `body` es obligatorio para todos los commits excepto los que tenga scope "docs".
Cuando el body es requerido debe tener al menos 20 caracteres.
Any line of the commit message cannot be longer than 100 characters! This allows the message to be easier
to read on GitHub as well as in various git tools.
El `footer` es opcional.
The footer should contain a [closing reference to an issue](https://help.github.com/articles/closing-issues-via-commit-messages/) if any.
Cualquier línea del mensaje del commit no puede tener más de 100 caracteres.
#### <ahref="commit-header"></a>Mensaje del header del commit
Samples: (even more [samples](https://github.com/angular/angular/commits/master))
```
<tipo>(<alcance>): <resumen>
│ │ │
│ │ └─⫸ Resumen corto escrito en modo imperativo, tiempo presente. Sin mayúsculas. Sin punto final.
│ │
│ └─⫸ Alcance del commit: animations|bazel|benchpress|common|compiler|compiler-cli|core|
└─⫸ Tipo de commit: build|ci|docs|feat|fix|perf|refactor|style|test
docs(changelog): update changelog to beta.5
```
```
fix(release): need to depend on latest rxjs and zone.js
The version in our package.json gets copied to the one we publish, and users need the latest of these.
```
El `<tipo>` y `<resumen>` son obligatorios, el `(<alcance>)` es opcional.
### Revert
If the commit reverts a previous commit, it should begin with `revert: `, followed by the header of the reverted commit. In the body it should say: `This reverts commit <hash>.`, where the hash is the SHA of the commit being reverted.
### Type
Must be one of the following:
##### Tipo
* **build**: Changes that affect the build system or external dependencies (example scopes: gulp, broccoli, npm)
* **ci**: Changes to our CI configuration files and scripts (example scopes: Circle, BrowserStack, SauceLabs)
* **docs**: Documentation only changes
* **feat**: A new feature
* **fix**: A bug fix
* **perf**: A code change that improves performance
* **refactor**: A code change that neither fixes a bug nor adds a feature
* **style**: Changes that do not affect the meaning of the code (white-space, formatting, missing semi-colons, etc)
* **test**: Adding missing tests or correcting existing tests
El tipo debe ser uno de los siguientes:
### Scope
The scope should be the name of the npm package affected (as perceived by the person reading the changelog generated from commit messages).
* **build**: cambios que afectan el sistema de compilación o dependencias externas (ejemplos de scopes: gulp, broccoli, npm)
* **ci**: cambios en nuestros archivos y scripts de configuración de CI (ejemplos de scopes: Circle, BrowserStack, SauceLabs)
* **docs**: cambios en la documentación
* **feat**: una nueva funcionalidad
* **fix**: una solución de un bug
* **perf**: un cambio de código que mejora el rendimiento.
* **refactor**: un cambio de código que no corrige ningún error ni agrega ninguna funcionalidad
* **style**: cambios que no afectan el significado del código (espacios en blanco, formato, falta de punto y coma, etc.)
* **test**: se agregan pruebas faltantes o se corrigen pruebas existentes
The following is the list of supported scopes:
* **animations**
* **bazel**
* **benchpress**
* **common**
* **compiler**
* **compiler-cli**
* **core**
* **elements**
* **forms**
* **http**
* **language-service**
* **localize**
* **platform-browser**
* **platform-browser-dynamic**
* **platform-server**
* **platform-webworker**
* **platform-webworker-dynamic**
* **router**
* **service-worker**
* **upgrade**
* **zone.js**
##### Alcance
El alcance debe ser el nombre del paquete npm afectado (tal como lo percibe la persona que lee el registro de cambios generado a partir de los mensajes de commit).
There are currently a few exceptions to the "use package name" rule:
La siguiente es la lista de alcances permitidos:
* **packaging**: used for changes that change the npm package layout in all of our packages, e.g.
public path changes, package.json changes done to all packages, d.ts file/format changes, changes
to bundles, etc.
* **changelog**: used for updating the release notes in CHANGELOG.md
* **docs-infra**: used for docs-app (angular.io) related changes within the /aio directory of the
repo
* **dev-infra**: used for dev-infra related changes within the directories /scripts, /tools and /dev-infra
* **ngcc**: used for changes to the [Angular Compatibility Compiler](./packages/compiler-cli/ngcc/README.md)
* **ve**: used for changes specific to ViewEngine (legacy compiler/renderer).
* none/empty string: useful for `style`, `test` and `refactor` changes that are done across all
packages (e.g. `style: add missing semicolons`) and for docs changes that are not related to a
specific package (e.g. `docs: fix typo in tutorial`).
* `animations`
* `bazel`
* `benchpress`
* `common`
* `compiler`
* `compiler-cli`
* `core`
* `elements`
* `forms`
* `http`
* `language-service`
* `localize`
* `platform-browser`
* `platform-browser-dynamic`
* `platform-server`
* `platform-webworker`
* `platform-webworker-dynamic`
* `router`
* `service-worker`
* `upgrade`
* `zone.js`
### Subject
The subject contains a succinct description of the change:
Actualmente hay algunas excepciones a la regla "usar el nombre de paquete":
* use the imperative, present tense: "change" not "changed" nor "changes"
* don't capitalize the first letter
* no dot (.) at the end
* `packaging`: usado para cambios que cambian el diseño de los paquetes de npm en todos nuestros paquetes. Ejemplos: cambios de la ruta públic, package.json cambios hechos a todos los paquetes, cambios a archivos o formatos d.ts, cambios a bundles, etc.
### Body
Just as in the **subject**, use the imperative, present tense: "change" not "changed" nor "changes".
The body should include the motivation for the change and contrast this with previous behavior.
* `changelog`: utilizado para actualizar las notas de la versión en CHANGELOG.md
### Footer
The footer should contain any information about **Breaking Changes** and is also the place to
reference GitHub issues that this commit **Closes**.
* `dev-infra`: utilizado para cambios relacionados con dev-infra dentro de los directorios /scripts, /tools y /dev-infra
**Breaking Changes** should start with the word `BREAKING CHANGE:` with a space or two newlines. The rest of the commit message is then used for this.
* `docs-infra`: utilizado para cambios relacionados con la documentación (angular.io) dentro del directorio /aio del repositorio
A detailed explanation can be found in this [document][commit-message-format].
* `migrations`: utilizado para los cambios en las migraciones `ng update`.
## <aname="cla"></a> Signing the CLA
* `ngcc`: usado para los cambios del [Compilador de compatibilidad de Angular](./packages/compiler-cli/ngcc/README.md)
Please sign our Contributor License Agreement (CLA) before sending pull requests. For any code
changes to be accepted, the CLA must be signed. It's a quick process, we promise!
* `ve`: utilizado para cambios específicos de ViewEngine (legacy compiler/renderer).
* For individuals, we have a [simple click-through form][individual-cla].
* For corporations, we'll need you to
[print, sign and one of scan+email, fax or mail the form][corporate-cla].
* alcance vacío: útil para cambios de `style`, `test` y `refactor` que se realizan en todos los paquetes (ejemplo: `style: add missing semicolons`) y para cambios de la documentación que no están relacionados a un paquete en específico(ejemplo: `docs: corrige error gramatical en el tutorial`).
<hr>
##### Resumen
Usa el campo resumen para proporcionar una descripción breve del cambio:
* usa el modo imperativo, tiempo presente: "cambia" no "cambió" o "cambios"
* no debe de contener ninguna letra mayúscula
* no debe de conter punto (.) al final
#### Mensaje del cuerpo del commit
Tal como en el resumen, usa el modo imperativo, tiempo presente: "cambia" no "cambió" o "cambios".
Explica la razón del cambio en el el mensaje del cuerpo del commit. Este mensaje de confirmación debe explicar _por qué_ está realizando el cambio.
Puedes incluir una comparación del comportamiento anterior con el nuevo comportamiento para ilustrar el impacto del cambio.
#### Mensaje del footer del commit
El footer puede contener información sobre cambios significativos y también es el lugar para hacer referencia a issues de GitHub, tickets de Jira y otros PRs que están relacionados con el commit.
La sección de cambios significativos debería comenzar con la frase "CAMBIO SIGNIFICATIVO: " seguido de un resumen del cambio significativo, una línea en blanco y una descripción detallada del cambio significativo que también incluya instrucciones de migración.
### Revirtiendo commits
Si el commit revierte un commit previo, el commit debería comenzar con `revert: `, seguido por el header del commit revertido.
El contenido del mensaje del commit debería contener:
- Información sobre el SHA del commit que se revierte en el siguiente formato: `Esto revierte el commit <SHA>`,
- Una descripción clara de la razón para revertir el mensaje del _commit_.
## <aname="cla"></a> Firma del Acuerdo de Licencia de Colaborador (CLA)
Por favor firma nuestro Acuerdo de Licencia de Colaborador (CLA) cuando creas tu primer pull request. Para que cualquier cambio de código sea aceptado, el Acuerdo de Licencia de Colaborador (CLA) debe ser firmado. Es un proceso rápido con nuestro CLA assistant que está integrado con nuestro CI.
Los siguientes documentos pueden ayudarte a resolver problemas con cuentas de GitHub y múltiples direcciones de correo electrónico:
If you have more than one Git identity, you must make sure that you sign the CLA using the primary email address associated with the ID that has been granted access to the Angular repository. Git identities can be associated with more than one email address, and only one is primary. Here are some links to help you sort out multiple Git identities and email addresses:
Note that if you have more than one Git identity, it is important to verify that you are logged in with the same ID with which you signed the CLA, before you commit changes. If not, your PR will fail the CLA check.

## Tareas de desarrollador
## Developer tasks
Nosotros usamos [Yarn](https://yarnpkg.com) para gestionar las dependencias y crear tareas de compilación.
Debes ejecutar todas estas tareas desde la carpeta `angular/aio`.
Aquí están las tareas más importantes que podrías necesitar usar:
We use [Yarn](https://yarnpkg.com) to manage the dependencies and to run build tasks.
You should run all these tasks from the `angular/aio` folder.
Here are the most important tasks you might need to use:
* `yarn` - instalar todas las dependencias.
* `yarn setup` - instalar todas las dependencias, boilerplate, stackblitz, zips y ejecuta dgeni en los documentos.
* `yarn setup-local` - igual que `setup`, pero crea los paquetes de Angular a partir del código y usa estas versiones construidas localmente (en lugar de las recuperadas desde npm) para aio y ejemplos de documentos boilerplate.
* `yarn` - install all the dependencies.
* `yarn setup` - install all the dependencies, boilerplate, stackblitz, zips and run dgeni on the docs.
* `yarn setup-local` - same as `setup`, but build the Angular packages from the source code and use these locally built versions (instead of the ones fetched from npm) for aio and docs examples boilerplate.
* `yarn build` - crear una compilación de producción de la aplicación (después de instalar dependencias, boilerplate, etc).
* `yarn build-local` - igual que `build`, pero usa `setup-local` en lugar de`setup`.
* `yarn build-local-with-viewengine` - igual que `build-local`, pero además también enciende el modo `ViewEngine` (pre-Ivy) en aio.
(Nota: Encender el modo `ViewEngine` en ejemplos de documentos, ver `yarn boilerplate:add:viewengine` abajo.)
* `yarn build` - create a production build of the application (after installing dependencies, boilerplate, etc).
* `yarn build-local` - same as `build`, but use `setup-local` instead of`setup`.
* `yarn build-local-with-viewengine` - same as `build-local`, but in addition also turns on `ViewEngine` (pre-Ivy) mode in aio.
(Note: To turn on `ViewEngine` mode in docs examples, see `yarn boilerplate:add:viewengine` below.)
* `yarn start` - ejecutar un servidor web de desarrollo que observa los archivos; luego crea el doc-viewer y vuelve a cargar la página, según sea necesario.
* `yarn serve-and-sync` - ejecutar ambos, el `docs-watch` y `start` en la misma consola.
* `yarn lint` - comprobar que el código del doc-viewer sigue nuestras reglas de estilo.
* `yarn test` - observar todos los archivos de origen, para el doc-viewer, y ejecuta todas las pruebas unitarias cuando haya algún cambio.
* `yarn test --watch=false` -ejecutar todas las pruebas unitarias una sola vez.
* `yarn e2e` - ejecutar todas las pruebas de e2e para el doc-viewer.
* `yarn start` - run a development web server that watches the files; then builds the doc-viewer and reloads the page, as necessary.
* `yarn serve-and-sync` - run both the `docs-watch` and `start` in the same console.
* `yarn lint` - check that the doc-viewer code follows our style rules.
* `yarn test` - watch all the source files, for the doc-viewer, and run all the unit tests when any change.
* `yarn test --watch=false` - run all the unit tests once.

## Usando ServiceWorker localmente
## Using ServiceWorker locally
Ejecutando `yarn start` (incluso cuando se apunta explícitamente al modo de producción) no configura el
ServiceWorker. Si quieres probar el ServiceWorker localmente, puedes usar `yarn build` y luego
ejecutar los archivos en `dist/` con`yarn http-server dist -p 4200`.
Running `yarn start` (even when explicitly targeting production mode) does not set up the
ServiceWorker. If you want to test the ServiceWorker locally, you can use `yarn build` and then
serve the files in `dist/` with`yarn http-server dist -p 4200`.
## Guía de autoría
Existen dos tipos de contenido en la documentación:
## Guide to authoring
* **Documentación de API**: descripciones de los módulos, clases, interfaces, decoradores, etc que son parte de la plataforma Angular.
La documentacion de API está generada directamente desde el código fuente.
El código fuente está contenido en archivos TypeScript , almacenados en la carpeta `angular/packages`.
Cada elemento de la API puede tener un comentario anterior, el cual contiene etiquetas y contenido de estilos JSDoc.
El contenido está escrito en markdown.
There are two types of content in the documentation:
* **Otro contenido**: guias, tutoriales, y otro material de marketing.
Todos los demás contenidos se escriben utilizando markdown en archivos de texto, ubicados en la carpeta `angular/aio/content`.
Más específicamente, hay subcarpetas que contienen tipos particulares de contenido: guías, tutoriales y marketing.
* **API docs**: descriptions of the modules, classes, interfaces, decorators, etc that make up the Angular platform.
API docs are generated directly from the source code.
The source code is contained in TypeScript files, located in the `angular/packages` folder.
Each API item may have a preceding comment, which contains JSDoc style tags and content.
The content is written in markdown.
* **Ejempos de código**: los ejemplos de código deben ser comprobables para garantizar su precisión.
Además, nuestros ejemplos tienen un aspecto específico y permiten al usuario copiar el código fuente. Para mayor
ejemplos se representan en una interfaz con pestañas (e.g. template, HTML, y TypeScript en pestañas separadas). Adicionalmente, algunos son ejemplos en acción, que proporcionan enlaces donde se puede editar el código, ejecutar, y/o descargar. Para obtener más detalles sobre cómo trabajar con ejemplos de código, lea los [fragmentos de código](https://docs.angular.lat/guide/docs-style-guide#code-snippets), [código fuente de marcado ](https://docs.angular.lat/guide/docs-style-guide#source-code-markup), y [ ejemplos en acción ](https://docs.angular.lat/guide/docs-style-guide#live-examples) paginas de los [ autores de guías de estilo ](https://docs.angular.lat/guide/docs-style-guide).
* **Other content**: guides, tutorials, and other marketing material.
All other content is written using markdown in text files, located in the `angular/aio/content` folder.
More specifically, there are sub-folders that contain particular types of content: guides, tutorial and marketing.
Usamos la herramienta [dgeni](https://github.com/angular/dgeni) para convertir estos archivos en docs que se pueden ver en el doc-viewer.
Las [guías de estilo para Autores](https://docs.angular.lat/guide/docs-style-guide) prescriben pautas para
escribir páginas de guía, explica cómo usar la documentación de clases y componentes, y cómo marcar el código fuente para producir fragmentos de código.
* **Code examples**: code examples need to be testable to ensure their accuracy.
Also, our examples have a specific look and feel and allow the user to copy the source code. For larger
examples they are rendered in a tabbed interface (e.g. template, HTML, and TypeScript on separate
tabs). Additionally, some are live examples, which provide links where the code can be edited, executed, and/or downloaded. For details on working with code examples, please read the [Code snippets](https://angular.io/guide/docs-style-guide#code-snippets), [Source code markup](https://angular.io/guide/docs-style-guide#source-code-markup), and [Live examples](https://angular.io/guide/docs-style-guide#live-examples) pages of the [Authors Style Guide](https://angular.io/guide/docs-style-guide).
### Generando documentos completos
We use the [dgeni](https://github.com/angular/dgeni) tool to convert these files into docs that can be viewed in the doc-viewer.
La principal tarea para generar los documentos es `yarn docs`. Esto procesará todos los archivos fuente (API y otros), extrayendo la documentación y generando archivos JSON que pueden ser consumidos por el doc-viewer.
The [Authors Style Guide](https://angular.io/guide/docs-style-guide) prescribes guidelines for
writing guide pages, explains how to use the documentation classes and components, and how to markup sample source code to produce code snippets.
### Generación parcial de doc para editores
### Generating the complete docs
La generación completa de documentos puede llevar hasta un minuto. Eso es demasiado lento para la creación y edición eficiente de documentos.
The main task for generating the docs is `yarn docs`. This will process all the source files (API and other),
extracting the documentation and generating JSON files that can be consumed by the doc-viewer.
Puedes ealizar pequeños cambios en un editor inteligente que muestre un markdown con formato:
>En VS Code, _Cmd-K, V_ abre la vista previa de markdown en el panel lateral; _Cmd-B_ alterna la barra izquierda
### Partial doc generation for editors
Puedes también mirar los cambios que se muestran correctamente en el doc-viewer
con un tiempo de ciclo rápido de edición / visualización.
Full doc generation can take up to one minute. That's too slow for efficient document creation and editing.
Para este propósito, usa la tarea `yarn docs-watch`, que observa los cambios en los archivos de origen y solo vuelve a procesar los archivos necesarios para generar los documentos relacionados con el archivo que ha cambiado.
Dado que esta tarea tiene accesos directos, es mucho más rápido (a menudo menos de 1 segundo) pero no producirá contenido de fidelidad completa. Por ejemplo, los enlaces a otros documentoss y ejemplos de código pueden no mostrarse correctamente. Esto se nota especialmente en los enlaces a otros documentos y en los ejemplos incrustados, que no siempre se representan correctamente.
You can make small changes in a smart editor that displays formatted markdown:
>In VS Code, _Cmd-K, V_ opens markdown preview in side pane; _Cmd-B_ toggles left sidebar
La configuración general es la siguiente:
You also want to see those changes displayed properly in the doc viewer
with a quick, edit/view cycle time.
* Abrir una terminal, estar seguro que las dependencias están instaladas; ejecutar una generación inicial del doc; luego iniciar el doc-viewer:
For this purpose, use the `yarn docs-watch` task, which watches for changes to source files and only
re-processes the files necessary to generate the docs that are related to the file that has changed.
Since this task takes shortcuts, it is much faster (often less than 1 second) but it won't produce full
fidelity content. For example, links to other docs and code examples may not render correctly. This is
most particularly noticed in links to other docs and in the embedded examples, which may not always render
correctly.
The general setup is as follows:
* Open a terminal, ensure the dependencies are installed; run an initial doc generation; then start the doc-viewer:
```bash
yarn setup
yarn start
```
* Abrir una segunda terminal e iniciar el observador de documentos.
* Open a second terminal and start watching the docs
```bash
yarn docs-watch
```
>Alternativamente, prueba el comando fusionado `serve-and-sync` que crea, observa y ejecuta en la misma ventana de la terminal
>Alternatively, try the consolidated `serve-and-sync` command that builds, watches and serves in the same terminal window
```bash
yarn serve-and-sync
```
* Abre un navegador con la siguiente dirección https://localhost:4200/ y navega hasta el documento en el que quieras trabajar.
Puedes automáticamente abrir el navegador utilizando `yarn start -o` en la primera terminal.
* Open a browser at https://localhost:4200/ and navigate to the document on which you want to work.
You can automatically open the browser by using `yarn start -o` in the first terminal.
* Realiza cambios en la página de documentación asociada o en los archivos de ejemplo. Cada vez que un archivo es guardado, la documentación se regenerará, la aplicación se reconstruirá y la página se volverá a cargar.
* Make changes to the page's associated doc or example files. Every time a file is saved, the doc will
be regenerated, the app will rebuild and the page will reload.
*Si recibes un error de compilación acerca de los ejemplos o cualquier otro error, asegúrate de consultar las
[guías de estilo para Autores](https://angular.io/guide/docs-style-guide) para más información.
* If you get a build error complaining about examples or any other odd behavior, be sure to consult
the [Authors Style Guide](https://angular.io/guide/docs-style-guide).

The [ng generate](cli/generate) and [ng add](cli/add) commands take as an argument the artifact or library to be generated or added to the current project.
In addition to any general options, each artifact or library defines its own options in a *schematic*.
Schematic options are supplied to the command in the same format as immediate command options.
### Building with Bazel
Optionally, you can configure the Angular CLI to use [Bazel](https://docs.bazel.build) as the build tool. For more information, see [Building with Bazel](guide/bazel).
