This only sets the symbolizer for our more used targets; not sure if there's a great way to set it everywhere (I suppose I could try wrapping cc_binary etc rules if there's a strong preference). There is a downside here, symbolizing a fastbuild crash seems to take about 3s. Not sure if there's a good way to get a faster llvm-symbolizer execution...? I tried running with the new LLVM update without the LLVM_SYMBOLIZER_PATH, and it looks like that's insufficient. With the settings, I now get readable crashes: ``` #9 0x000055dc007d1724 void Carbon::Internal::CheckFail<Carbon::TemplateString<5>{"FATAL"}, Carbon::TemplateString<27>{"toolchain/driver/driver.cpp"}, 84, Carbon::TemplateString<0>{}, Carbon::TemplateString<3>{"err"}>() (/usr/local/google/home/jperkins/.cache/bazel/_bazel_jperkins/85deb7d9d96f7e0e80b42618a55969d7/sandbox/linux-sandbox/9383/execroot/_main/bazel-out/k8-fastbuild/bin/toolchain/testing/file_test.runfiles/_main/toolchain/testing/file_test+0x2894724) ``` Note the LLVM update is for https://github.com/llvm/llvm-project/pull/109021

"""Bazel modules.
|
|
|
|
`MODULE.bazel.lock` may change locally when `bazel` is executed. This means one
|
|
of:
|
|
|
|
1. `MODULE.bazel` is changing.
|
|
- Running `bazel mod deps` provides a canonical update to
|
|
`MODULE.bazel.lock`; include the changes.
|
|
- GitHub test actions may also identify platform-specific lockfile
|
|
updates.
|
|
2. The `bazel` version doesn't match the version used to generate the
|
|
`MODULE.bazel.lock`.
|
|
- Bazel releases can change the lock file contents.
|
|
- We use Bazelisk in order to keep everyone using the same version:
|
|
https://bazel.build/install/bazelisk
|
|
- Developers are encouraged to alias `bazel` to `bazelisk` for
|
|
ease-of-use; some setups, like Homebrew, will include that with a
|
|
`bazelisk` install.
|
|
- Contribution tools documentation includes `bazelisk` setup:
|
|
https://github.com/carbon-language/carbon-lang/blob/trunk/docs/project/contribution_tools.md
|
|
- Make sure `bazelisk --version` (or `bazel --version`) matches the
|
|
version in `.bazeliskrc`.
|
|
3. The host platform hasn't yet been added to the lock file.
|
|
- Platforms tested with GitHub actions are kept up-to-date. Other
|
|
platforms may fall out of sync due to `bazel` or dependency changes,
|
|
and should be updated with a PR the same way a platform is added.
|
|
- Running `bazel mod deps` provides a canonical update to
|
|
`MODULE.bazel.lock`; create a PR with those changes in order to include
|
|
the host platform.
