The last commit passed CI, so this final bump is just to allow for
deviation caused by different loads on the runner machines. With this
change, I don't expect any current unit test to ever time out, even when
CI is under extreme load.
Because we don't pass -fqemu and -fwasmtime on aarch64-linux, we're just
spending a bunch of time compiling all these module tests only to not even run
them. x86_64-linux already covers both compiling and running them.
Reduced number of runners from 9 to 6.
This number is the total physical memory (251G) divided by the number of
runners we have active (6).
see previous commit 5b9e528bc550e7ea9e286fdd2324316f9895d5da
We already do these on the x86_64-linux machines. They're fairly costly, and it
seems very unlikely to me that they'll uncover issues that wouldn't be uncovered
on x86_64-linux.
Otherwise the disk just keeps getting filled up.
Also remove some pointless cleanup commands since the actions/checkout workflow
step already cleans the repository by default.
There was already `zig build test-fmt` but now `zig build test` depends
on that one.
The CI scripts no longer need explicit logic since they already do
`zig build test`.
This introduces the new test step `test-c-import`, and removes the
ability of the behavior tests to `@cImport` paths relative to `test`.
This allows the behavior tests to be run without translate c.
For computing the zig version number, pass --abbrev=9 rather than
requiring the user to set their git configuration in order to make zig
versions match the standard.
This reverts commit 4d1432299fe5dccef1e8254800e365c4d6c0d435.
Please don't hard-code unrelated concerns this way. build.zig should not
have awareness of the naming conventions for cmake build directories.
We already have a zig build step for this: test-fmt.
* Rename the test-fmt step to check-fmt.
test-fmt sounds like it runs tests for `zig fmt` itself (lib/std/zig/render.zig).
* Use it instead of `zig fmt --check` in the CI scripts.
* Also use it in CI scripts that didn't have this check before.
* build.zig: introduce `-Dflat` option which makes the installation
match what we want to ship for our download tarballs. This allows
deleting a bunch of shell script logic from the CI.
- for example it puts the executable directly in prefix/zig rather
than prefix/bin/zig and it additionally includes prefix/LICENSE.
* build.zig: by default also install std lib documentation to doc/std/
- this can be disabled by `-Dno-autodocs` similar to how there is
already `-Dno-langref`.
* build.zig: add `std-docs` and `langref` steps which build and install
the std lib autodocs and langref to prefix/doc/std and
prefix/doc/langref.html, respectively.
* std.Build: implement proper handling of `-femit-docs` using the
LazyPath system. This is a breaking change.
- this is a partial implementation of #16351
* frontend: fixed the handling of Autodocs with regards to caching and
putting the artifacts in the proper location to integrate with the
build system.
- closes#15864
* CI: delete the logic for autodocs since it is now handled by build.zig
and is enabled by default.
- in the future we should strive to have nearly all the CI shell
script logic deleted in favor of `zig build` commands.
* CI: pass `-DZIG_NO_LIB=ON`/`-Dno-lib` except for the one command where
we want to actually generate the langref and autodocs. Generating the
langref takes 14 minutes right now (why?!) so we don't want to do that
more times than necessary.
* Autodoc: fixed use of a global variable. It works fine as a local
variable instead.
- note that in the future we will want to make Autodoc run
simultaneously using the job system, but for now the principle of
YAGNI dictates that we don't have an init()/deinit() API and instead
simply call the function that does the things.
* Autodoc: only do it when there are no compile errors
to avoid getting OOM killed. We need to have a high number of GitHub
Actions runners simultaneously active, otherwise the hardware ends up
underutilized. But with zig build running in parallel now, this
sometimes results in memory usage spikes that have been causing the
runner to get killed.
This number is the total physical memory (251G) divided by the number of
runners we have active (11).
See related commit 2d41dac57d3afdd5fe3d03be08ff0a24833f61dd which did
the same but for our x86_64-linux machines.
Zig's build script has several race conditions preventing proper
concurrent builds from working. By using -j1 for now, finishing this
branch (concurrent zig builds) is untangled from the separate problem of
correcting concurrency issues with zig's own build script.
In other words, let's solve one problem at a time.
In particular, these two changes are relevant:
* zig cc: support -stack in addition to --stack for linker arg
- Fixes stack overflow when running zig2 on aarch64-macos.
* compiler_rt: avoid using weak aliases
- Fixes duplicate symbol when linking zig2 on aarch64-linux.
