Paul Gschwendtner 12443ea739 build: remove `skydoc` and `rules_sass` from repository (#42760)
Skydoc is no longer used as `@angular/bazel` is no longer a
public API. The Sass rules were only used in a single place
in the repo where Sass is not really needed and has just been
added by accident most likely. We want to remove the Sass dependency
in preparation for Rules NodeJS v4.x where the Sass rules currently
still use an older version of `@bazel/worker` that is incompatible.

How to run the benchmarks locally

Run in the browser

yarn bazel run modules/benchmarks/src/tree/{name}:devserver

# e.g. "ng2" tree benchmark:
yarn bazel run modules/benchmarks/src/tree/ng2:devserver

Run e2e tests

# Run e2e tests of individual applications:
yarn bazel test modules/benchmarks/src/tree/ng2/...

# Run all e2e tests:
yarn bazel test modules/benchmarks/...

Use of *_aot.ts files

The *_aot.ts files are used as entry-points within Google to run the benchmark tests. These are still built as part of the corresponding ng_module rule.

Specifying benchmark options

There are options that can be specified in order to control how a given benchmark target runs. The following options can be set through test environment variables:

  • PERF_SAMPLE_SIZE: Benchpress performs measurements until scriptTime predictively no longer decreases. It does this by using a simple linear regression with the amount of samples specified. Defaults to 20 samples.
  • PERF_FORCE_GC: If set to true, @angular/benchpress will run run the garbage collector before and after performing measurements. Benchpress will measure and report the garbage collection time.
  • PERF_DRYRUN: If set to true, no results are printed and stored in a json file. Also benchpress only performs a single measurement (unlike with the simple linear regression).

Here is an example command that sets the PERF_DRYRUN option:

yarn bazel test modules/benchmarks/src/tree/baseline:perf --test_env=PERF_DRYRUN=true
