This PR makes building CMake based packages easier.
- Introduce a custom toolchain file for Pyodide. It inherits most of settings from the original Emscripten toolchain file with some modifications. Packages built by pyodide-build will automatically use that toolchain file.
- Proxy cmake in pywasmcross.py, in order to proxy other compiler toolchains.
This PR adds the Robot Raconteur Pyodide package, which is a modified version
of Robot Raconteur designed to run in the Pyodide environment, using WebSockets
for communication. See robotraconteur/robotraconteur for the full version of the
package. Robot Raconteur is used to communicate with robots and other automation
components, and has a large library of drivers and packages: robotraconteur/robotraconteur-directory.
It is used as the bases for PyRI, a robotics programming environment:
https://github.com/pyri-project/pyri-core/blob/master/README.md. Using a bridge, this package can
also be used to communicate with ROS2 networks: robotraconteur-contrib/robotraconteur_ros2_bridge
This drops the Rust patch and "Throw away errors in minify wasm_js" which
I suspect was fixed by an emscripten update (I'm not sure how long ago). It
replaces the two remaining emscripten patches with new versions that match
the versions I am upstreaming.
This enables WASM_BIGINT while maintaining (hypothetical) Safari 14 support
by shimming BigInt64Array and BigUint64Array if they are missing. I think the
last time we tried to enable WASM_BIGINT was before #2019 so our chances
are significantly better this time.
This will fix dynamic linking bugs and yields a minor reduction in code size.
The goal of this commit is to add the capability of skipping specific tests by
glob pattern. Many core test sets have just one test that uses subprocess or
threads. Others have a few tests that are failing due to upstream problems in
emscripten. I went through and switched to skipping specific tests in as many
cases as I could. In modules where most or all tests use threading or
subprocess, I gave up and put a comment saying something like 35/50 tests fork
and I didn't want to bother to salvage the remaining ones.
In order to accommodate using patterns to skip specific tests (and also extra
comments) I switched the format of python_tests to a yaml file. This gives us
significantly more flexibility in the structure of the file and allows us to use
ruamel.yaml to update it. We gain a lot flexibility while reducing the length of
make_test_lists.py modestly from 108 to 78 loc.
In the future, hopefully we should be able to make fixes by deleting one skip
pattern and looking into why that particular test fails.
Having to add `emsdk/upstream/emscripten` to all the emscripten patches is a
nuisance. If at some point we want to patch a file in a different folder, we can
separate the patches into multiple folders. In particular this should make it
easy to migrate patches using `git am`, `git rebase`, and `git format-patch`.
Binaryen now invokes cc instead of gcc, and the cc symlink isn't in
/usr/lib/ccache. This replaces the implementation in #1014.
This has the disadvantage that build is now broken if ccache is not
available.
