Some Bazel projects started failing

[DavidKorczynski]

I was looking at why fuzztest-raksha is failing to build and I think it's a bazel issue. The samme issue happens in tcmalloc

Example log:

Please use constraints from @platforms repository embedded in Bazel, or preferably declare dependency on https://github.com/bazelbuild/platforms. See https://github.com/bazelbuild/bazel/issues/8622 for details.

It seems to be this issue bazelbuild/bazel#8622 and probably not something we should fix, but rather the projects themselves should fix. Other projects started observing this issue as well (e.g. google/googletest#4096). Am not entirely sure if we can do something but leaving this open for tracking.

The issue seems to be a bit project specific -- for projects that rely on rules_fuzzing (which will be at least all projects that use bazel_build_fuzz_tests) should downgrade to bazel 5.4.0 or wait until bazel-contrib/rules_fuzzing#222 is fixed. See an example for this in the following PR for tcmalloc: #9304

The issue may happen in other projects that use bazel. Downgrading to 5.4.0 is still an option there but may not be possible -- e.g. was the case in Raksha #9297

for projects that rely on rules_fuzzing (which will be at least all projects that use bazel_build_fuzz_tests)

Going over the list of projects using rules_fuzzing I found that only one project (tcmalloc) failed, the rest was working or failing due to other reasons (now fixed in #9305).

Can this be closed then? :-)

Yeah, I think so, thanks!
