This commit updates the release process of `wasi-sdk` to remove most
of the manual interaction and steps done. Instead now draft releases are
automatically created for tags made. This means that there's only two
steps necessary: (1) pushing a tag and (2) hitting publish on the
generated release. This commit also removes a number of the CI scripts
previously used to manage releases.
* Rewrite the build system with CMake
This commit is an attempt to provide a concrete path forward on
WebAssembly/wasi-sdk#425. I personally think it's pretty important to
get the ability to have more architectures here but at the same time I
also think it's important to to take this as an opportunity to refactor
and improve the build system of this repository. To that end this
represents my attempt to improve the status quo.
This removes the old `Makefile` and replaces it with a CMake-based
system to build all these projects. Overall this is intended to be a "no
functional change" intended sort of refactoring. Changing build systems
inevitably causes issues, however, so this change additionally has a
very high likelihood of needing follow-up fixes. At a high enough level
this commit introduces two major changes to how this repository is
built:
1. The `make`-based system (the root `Makefile`) is replaced with CMake.
This additionally updates tests to use CMake.
2. A single "build" is split into either building a toolchain or
building a sysroot. This enables builds to only build one or the
other as necessary.
The first change, using CMake, is due to the fact that using `make` on
Windows basically is not pleasant coupled with the fact that more
advanced logic, such as changing flags, compilers, etc, is much easier
with a CMake-based system. The second change is intended to cover the
use case of #425 in addition to refactoring the current build.
Throughout this change I have intentionally not tried to keep a 1:1
correspondance with behaviors in the old `Makefile` because much of this
PR is intended to address shortcomings in the old build system. A list
of changes, improvements, etc, made here are:
* CMake provides a much nicer portability story to Windows than `make`.
This is moving towards the direction of not needing `bash`, for
example, to build an SDK. Currently `wasi-libc` still requires this,
but that's now the only "hard" dependency.
* The set of targets built can now be configured for smaller builds
and/or debugging just a single target. All WASI targets are still
built by default but it's much easier to add/remove them.
* Different targets are now able to be built in parallel as opposed to
the unconditional serial-nature of the `Makefile`.
* Use of `ninja` is no longer required and separate build systems can be
used if desired.
* The sysroot and the toolchain can now be built with different CMake
build profiles. For example the `Makefile` hardcoded `MinSizeRel` and
`RelWithDebInfo` and this can now be much more easily customized by
the SDK builder.
* Tarballs are now more consistently produced and named. For a tarball
of the name `foo.tar.gz` it's guaranteed that there's a single folder
`foo` created when unpacking the tarball.
* The macOS binaries are no longer hybrid x64/arm64 binaries which
greatly inflates the size of the SDK. There's now a separate build for
each architecture.
* CI now produces arm64-linux binaries. The sysroot is not built on the
arm64-linux builder and the sysroot from the x86_64-linux builder is
used instead.
* Tests are almost ready to execute on Windows, there's just a few minor
issues related to exit statuses and probably line endings which need
to be worked out. Will require someone with a Windows checkout, however.
* Tests are now integrated into CMake. This means that the wasm binaries
are able to be built in parallel and the tests are additionally
executed in parallel with `ctest`. It is possible to build/run a
single test. Tests no longer place all of their output in the source
tree.
* Out-of-tree builds are now possible and the build/installation
directories can both be customized.
* CI configuration of Windows/macOS/Linux is much more uniform by having
everything in one build matrix instead of separate matrices.
* Linux builds are exclusively done in docker containers in CI now. CI
no longer produces two Linux builds only for one to be discarded when
artifacts are published.
* Windows 32-bit builds are no longer produced in CI since it's expected
that everyone actually wants the 64-bit ones instead.
* Use of `ccache` is now automatically enabled if it's detected on the
system.
* Many preexisting shell scripts are now translated to CMake one way or
another.
* There's no longer a separate build script for how to build wasi-sdk in
docker and outside of docker which needs to be kept in sync,
everything funnels through the same script.
* The `docker/Dockerfile` build of wasi-sdk now uses the actual
toolchain built from CI and additionally doesn't duplicate various
CMake-based configuration files.
Overall one thing I want to additionally point out is that I'm not CMake
expert. I suspect there's lots of little stylistic and such improvements
that can be made.
* Fix skipping tests on windows
* Fetch a full depth in the finalize workflow too
* Fix multi-arch docker build
* Fix assembling of sysroot
* Fix script syntax
* Clean up the merge script slightly
* Remove Pat's email
* Move configuration of CMAKE_EXECUTABLE_SUFFIX
* Remove redundant sysroot option
* Fix comment in testcase.sh
* Update new p2 cmake files
* Remove now-duplicate wasi-sdk-p2.cmake
This helps ensure the identically-named 32-bit tarfile doesn't overwrite the
64-bit one when we extract everything into a single directory.
I'll follow this up by making an updated wasi-sdk-22.0.m-mingw.tar.gz and adding
it to the wasi-sdk-22 release.
Fixes#326

When testing out these scripts on a fork, I realized that it was more
convenient to use a single environment variable (e.g.,
`GITHUB_API_URL=... ci/draft-release.sh`) to change some of the script's
input parameters.
This change refactors the script logic that checks if a workflow in fact
built the commit matching our release tag out into a separate script.
This is mainly an improvement in clarity.
Previously, the release process for wasi-sdk was undocumented and
manual. The `RELEASING.md` document in this commit describes the steps
necessary to publish a new version of `wasi-sdk` as a GitHub release and
provides helpful scripts to automate some of the steps.
With this in place, a future change could add a workflow trigger that
allows running the steps automatically in GitHub actions. Keeping the
steps as scripts in the repository, however, allows developers to re-run
steps themselves in the (likely) case that something goes awry.
