As of Angular Package Format v10, we no longer ship a `fesm5` and
`fesm5` output in packages. We made this change to the `ng_package`
rule but intentionally did not clean up related build actions.
This follow-up commit cleans this up by:
* No longer building fesm5 bundles, or providing esm2015 output.
* No longer requesting and building a third flavor for ESM5. We can
use TSC to downlevel ES2015 sources/prodmode output similarly to how it
is done in `ng-packagr`.
The third output flavor (ESM5) resulted in a build slow-down as we
required a full recompilation of sources. Now, we only have a single
compilation for prodmode output, and then downlevel it on-demand
to ES5 for the UMD bundles. Here is timing for building the release
packages in `angular/angular` before this change, and afterwards:
* Before: 462.157s = ~7.7min
* After: 339.703s = ~5.6min
This signifies a time reduction by 27% when running
`./scripts/build/build-packages-dist.sh`.

Cleans up the dependencies used in the shared dev-infra package
configuration. With the recent benchmarking utilities that have
been added, a lot of peer dependencies have been added.
We decided that we don't want to list every used dependencies as
peer dependency as that could result in unnecessary churn/noise
for consumers of the dev-infra package. Additionally, not all parts
of the dev-infra package are necessarily used.
Due to this, we want to apply the following rules for the package
dependencies:
1. If a dependency is only used in a shipped Bazel macro/rule that can be
optionally consumed, omit it from `package.json`. Bazel reports the
missing dependency on its own, so we want to avoid adding it to the
package json file.
2. Otherwise, if the dependency is large and commonly used (like
buildifier), add it to the `peerDependencies`. If not, add it
to the dependencies that are always brought in. We consider it
as acceptable to bring in a few small dependencies that might not
be used or not. Making all of those option would complicate the
use of the dev-infra package.

The `ng_module` rule supports the generation of flat module bundles. In
View Engine, information about this flat module bundle is exposed
as a Bazel provider. This is helpful as other rules like `ng_package`
could rely on this information to determine entry-points for the APF.
With Ivy this currently does not work because the flat module
information is not exposed in the provider. The reason for this is
unclear. We should also provide this information in Ivy so that rules
like `ng_package` can also determine the correct entry-points when a
package is built specifically with `--config=ivy`.

Previously, this would only work if the ServiceWorker's [scope][2] was

request to `/some/path/ngsw/state` as matching `ngsw/state` and would
not serve it with the debugging information.

One of the ivy acceptance tests currently fails in IE10. This
is because we recently added a new test that asserts that injecting
`ViewRef` results in a `NullInjectorError`.
Due to limitations in TypeScript and in polyfills for `setPrototypeOf`,
the error cannot be thrown as `ViewRef` is always considered injectable.
In reality, `ViewRef` should not be injectable, as explicitly noted
in c00f4ab2ae.
There seems no way to simulate the proper prototype chain in such
browsers that do not natively support `__proto__`, so TypeScript
and `core-js` polyfills simply break the prototype chain and
assign inherited properties directly on `ViewRef`. i.e. so that
`ViewRef.__NG_ELEMENT_ID__` exists and DI picks it up.
There is a way for TypeScript to theoretically generate proper
prototype chain in ES5 output, but they intend to only bother
about the proper prototype chain in ES6 where `setPrototypeOf`
etc. are offically standarized. See the response:

The motivation behind this change is to improve the productivity in the angular/angular repo
without sacrificing the original goal of having better understanding of changes within
the repo.
When the minBodyLength limit was originally introduced the goal was simple: force
committers to provide more contextual information for each change coming into the
repo. Too often we found ourselves in a situation where nobody understood what
motivated some of the changes and we needed more contextual info to know if the
change was correct, desirable, and still relevant (at a later point in time).
When the limit was introduced, we needed to pick a minimum body length - given no
data, and frustration with even big changes being committed with just a words in
the subject (along the lines of "fix(core): fixing a bug"), we overcompensated
and started off with a really high bar of minBodyLength set to 100 chars.
This turned out to be impractical and created a big friction point in making valid
changes in the angular/angular repo, and in fact caused some of the refactorings
and smaller changes to be either skipped or combined into other commits which
increased the burden for code reviewers.
The evidence in the friction points can be seen in the number of PRs that fail to pass
the current lint check on the first try, but more importantly also in the "creative"
writing that some of the committers are forced to resort to in order to satisfy the
current checks. Examples:
- 286fbf42c6
- b2816a1536
Given that we primarily care to document the motivation behind each change
(the answer to the ultimate question: WHY?), I've collected several *common* &
*valid* commit messages that are minimalistic and capture the WHY sufficiently:
```
Refactoring for readability. => 28 chars
Improving variable naming. => 26 chars
Additional test coverage. => 25 chars
Cleaning up the code. => 21 chars
Simplified the code. => 20 chars
```
These commit message bodies in addition to the commit message subject should
sufficiently satisfy the need to capture the context and motivation behind each
change without creating an undue burden on committers.
Example minimalistic commit message:
------
refactor(core): cleanup the expression parser
Simplifying the code.
----
Given this research, I'm decreasing the minBodyLenth in angular/angular to 20 chars.
The commit message quality can be additionally improved by implementing a commit message
template via `.gitmessage` that will guide the committers in following our commit message
guidelines via instructions provided in the form of in-the-flow help rather than as an after
the fact lint check.
More info: https://thoughtbot.com/blog/better-commit-messages-with-a-gitmessage-template
I'm intentionally deferring such change for a separate PR as not to complicate or delay the
minBodyLength limit decrease.

Often changelogs are generated from the patch branch and then
cherry-picked into the `CHANGELOG.md` file in `master` for
better access and readability. This is problematic though as
`conventional-changelog` (the tool we use for generating the
changelog), will duplicate commits when a future changelog
is generated from `master` then (i.e. for a new minor release).
This happens because conventional-changelog always generates the
changelog from the latest tag in a given branch to `HEAD`. The
tag in the patch branch does not correspond to any SHA in `master`
so the intersection of commits is not automatically omitted.
We work around this naively (until we have a better tool provided
by dev-infra), by deduping commits that are already part of the
changelog. This has proven to work as expected in the components
repo.

The merge script uses `git cherry-pick` for both the API merge strategy
and the autosquash strategy. It uses cherry-pick to push commits to
different target branches (e.g. into the `10.0.x` branch).
Those commits never point to the commits that landed in the primary
Github branch though. For the autosquash strategy the pull request number
is always included, so there is a way to go back to the source. On the other
hand though, for commits cherry-picked in the API merge strategy, the
pull request number might not always be included (due to Github's
implementation of the rebase merge method).
e.g.
27f52711c0
For those cases we'd want to link the cherry-picked commits to the
original commits so that the corresponding PR is easier to track
down. This is not needed for the autosquash strategy (as outlined
before), but it would have been good for consistency. Unfortunately
though this would rather complicate the strategy as the autosquash
strategy cherry-picks directly from the PR head, so the SHAs that
are used in the primary branch are not known.

As part of angular.io's responsive layout, the menu shown in the top-bar
is collapsed into the sidenav on narrow screens at the point where the
search-bar (on the right side of the top-bar) would overlap with the
menu's nav-items.
Previously, the value used as break-point would work on marketing pages,
where the hamburger button is not shown on wide screens. However, on
docs pages (where the hamburger button is always shown, pushing the menu
further to the right), the search-bar would still overlap the menu
nav-items on some resolutions.
This commit fixes it by raising the screen width threshold at a value
that ensures there is no overlap even on pages where the hamburger
button is visible alongside the top-bar menu.

Currently when the `plural` or `select` keywords in an ICU contain trailing spaces (e.g. `{count, select , ...}`), these spaces are also included into the key names in ICU vars (e.g. "VAR_SELECT ").

Incremental compilation allows for the output state of one compilation to be
reused as input to the next compilation. This involves retaining references
to instances from prior compilations, which must be done carefully to avoid
memory leaks.
This commit fixes such a leak with a complicated retention chain:
* `TrackedIncrementalBuildStrategy` unnecessarily hangs on to the previous
`IncrementalDriver` (state of the previous compilation) once the current
compilation completes.
In general this is unnecessary, but should be safe as long as the chain
only goes back one level - if the `IncrementalDriver` doesn't retain any
previous `TrackedIncrementalBuildStrategy` instances. However, this does
happen:
* `NgCompiler` indirectly causes retention of previous `NgCompiler`
instances (and thus previous `TrackedIncrementalBuildStrategy` instances)
through accidental capture of the `this` context in a closure created in
its constructor. This closure is wrapped in a `ts.ModuleResolutionCache`
used to create a `ModuleResolver` class, which is passed to the program's
`TraitCompiler` on construction.
* The `IncrementalDriver` retains a reference to the `TraitCompiler` of the
previous compilation, completing the reference chain.
The final retention chain thus looks like:
* `TrackedIncrementalBuildStrategy` of current program
* `.previous`: `IncrementalDriver` of previous program
* `.lastGood.traitCompiler`: `TraitCompiler`
* `.handlers[..].moduleResolver.moduleResolutionCache`: cache
* (via `getCanonicalFileName` closure): `NgCompiler`
* `.incrementalStrategy`: `TrackedIncrementalBuildStrategy` of previous
program.
The closure link is the "real" leak here. `NgCompiler` is creating a closure
for `getCanonicalFileName`, delegating to its
`this.adapter.getCanonicalFileName`, for the purposes of creating a
`ts.ModuleResolutionCache`. The fact that the closure references
`NgCompiler` thus eventually causes previous `NgCompiler` iterations to be
retained. This is also potentially problematic due to the shared nature of
`ts.ModuleResolutionCache`, which is potentially retained across multiple
compilations intentionally.
This commit fixes the first two links in the retention chain: the build
strategy is patched to not retain a `previous` pointer, and the `NgCompiler`
is patched to not create a closure in the first place, but instead pass a
bound function. This ensures that the `NgCompiler` does not retain previous
instances of itself in the first place, even if the build strategy does
end up retaining the previous incremental state unnecessarily.
The third link (`IncrementalDriver` unnecessarily retaining the whole
`TraitCompiler`) is not addressed in this commit as it's a more
architectural problem that will require some refactoring. However, the leak
potential of this retention is eliminated thanks to fixing the first two
issues.

When ngcc creates an entry-point program, the `allowJs` option is enabled
in order to operate on the JavaScript source files of the entry-point.
A side-effect of this approach is that external modules that don't ship
declaration files will also have their JavaScript source files loaded
into the program, as the `allowJs` flag allows for them to be imported.
This may pose an issue in certain edge cases, where ngcc would inadvertently
operate on these external modules. This can introduce all sorts of undesirable
behavior and incompatibilities, e.g. the reflection host that is selected for
the entry-point's format could be incompatible with that of the external
module's JavaScript bundles.
To avoid these kinds of issues, module resolution that would resolve to
a JavaScript file located outside of the package will instead be rejected,
as if the file would not exist. This would have been the behavior when
`allowJs` is set to false, which is the case in typical Angular compilations.
