This is work in progress. Several language features are still unimplemented or only partially implemented. Instructions for running the compiler and its output can be found in pkg/dart2wasm/dart2wasm.md. These procedures are preliminary and expected to change. The best version of d8 to use for this version of dart2wasm is 10.0.40, as explained here: https://dart-review.googlesource.com/c/sdk/+/232097 This commit also adds a dart2wasm-hostasserts-linux-x64-d8 testing configuration to run the compiler over the test suite. The history of the prototype that this is based on can be seen here: https://github.com/askeksa-google/sdk/tree/wasm_prototype Issue: https://github.com/dart-lang/sdk/issues/32894 Change-Id: I910b6ff239ef9c5f66863e4ca97b39b8202cce85 Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/175728 Reviewed-by: Joshua Litt <joshualitt@google.com> Commit-Queue: Aske Simon Christensen <askesc@google.com>
Package validation
The packages in pkg/ are automatically validated on the LUCI CI bots. The
validation is largely done by the tools/package_deps package; it can be tested
locally via:
dart tools/package_deps/bin/package_deps.dart
Packages which are published
There are several packages developed in pkg/ which are published to pub.
Validation of these packages is particularly important because the pub tools are
not used for these packages during development; we get our dependency versions
from the DEPS file. Its very easy for the dependencies specified in a package's
pubspec file to get out of date wrt the packages and versions actually used.
In order to better ensure we're publishing correct packages, we validate some properties of the pubspec files on our CI system. These validations include:
- that the dependencies listed in the pubspec are used in the package
- that all the packages used by the source are listed in the pubspec
- that we don't use relative path deps to pkg/ or third_party/ packages
Packages which are not published
For packages in pkg/ which we do not intend to be published, we put the following comment in the pubspec.yaml file:
# This package is not intended for consumption on pub.dev. DO NOT publish.
publish_to: none
These pubspecs are still validated by the package validation tool. The contents are more informational as the pubspecs for these packages are not consumed by the pub tool or ecosystem.
We validate:
- that the dependencies listed in the pubspec are used in the package
- that all the packages used by the source are listed in the pubspec
- that a reference to a pkg/ package is done via a relative path dependency
