I have received the following statement from the past contributors
Luis Holanda, Jeremy Volkman and Fabian Hahn:
I hereby confirm that I am the copyright holder or authorized by the
copyright holder of this contribution. As such I hereby confirm that
all contributions made to bazel-zig-cc by me or on behalf of me,
hereby is licensed under the Apache 2.0 License
[http://www.apache.org/licenses/LICENSE-2.0]. I am aware that my
previous contributions will still be available under the MIT license
as well. I confirm that I am aware of the bazel-zig-cc teams intention
to release bazel-zig-cc under the Apache 2.0 License from release
[1.0] and onwards, and that the bazel-zig-cc no longer will accept
contributions made under the MIT and that any future submissions from
myself will be considered to be licensed under Apache 2.0 unless I
expressly state otherwise.
Copyright and re-licensing for Google and Uber employees has been
resolved internally.
Since not all contributors took action to re-license the code yet,
portions of bazel-zig-cc remain licensed as MIT.
I have started this project during my personal time with my personal
resources. I am now handing over all copyrights to this code to Uber
Technologies, Inc.
Until now we needed to maintain two versions of the zig launcher: one
for Windows and one for everything else. This was problematic for two
reasons:
1. I do not know powershell and thus keep breaking the Windows wrapper
all the time (see git history of Fabian fixing stuff that I broke).
2. This makes bazel-zig-cc dependent on the system shell, making it not
really hermetic. So the recently added
`--experimental_use_hermetic_linux_sandbox` does not work with
bazel-zig-cc, unless we bind-mount a bunch of stuff: `/usr`, `/bin`,
`/lib`, `/usr/lib:/lib`, `/usr/lib64:/lib64` and `/proc`.
Switching to a Zig-based wrapper solves both issues, and we can do this:
bazel build "$@" \
--experimental_use_hermetic_linux_sandbox \
--sandbox_add_mount_pair=/proc \
<...>
Zig itself still depends on `/proc` for `/proc/self/exe`, so we need to
keep that. I will look into reducing even that dependency separately.
Not all is nice and shiny though: this commit replaces ~80 LOC worth of
shell scripts wrappers with a singe ~300 LOC zig program, which is
arguably harder to understand. However, it is easier to change, at least
for me, because it's a single file with unit tests! Most importantly,
the gnarly code (which resolves paths and sets environment variables) is
cross-platform.
Thanks to Fabian Hahn for testing this on Windows and pointing out
errors.
Cache reuse in zig is currently quite fragile (we are using a forked
version with github.com/ziglang/zig/issues/13051), so ensure that it
does not regress when zig SDK upgrades.
It would "fix" the files on CI and not fail. ci/lint should verify they
are OK first, and give guidance to fix them.
also, `shellcheck -x` is no longer necessary; we can use the plain one
now.
This patch continues the work to support NixOS and others non-FHS
distributions by replacing instances of `/bin/bash` with
`/usr/bin/env bash`, which works correctly in more systems than the
former.

This removes all other Bazel test commands, so all tests can be again
tested with `bazel test ...`.
Also, fixes linux-arm64 glibc tests. Until now they've worked only in
CI. Now they work everywhere I tried.
- add rules to run tests for a specific platform
- use downloaded buildifier
- move lint to a script
- rename ci tasks
- stop running under qemu-aarch64-static as it doesn't do anything
