(I had to first solve a problem with "dubious file ownership" error that
was happening inside the grpc_repo_archive action when using the
concurrent wrapper).
Example:
```
tools/docker_runners/examples/concurrent_bazel.sh --bazelrc=tools/remote_build/linux.bazelrc test --genrule_strategy=remote,local --workspace_status_command=tools/bazelify_tests/workspace_status_cmd.sh //tools/bazelify_tests/test:runtests_csharp_linux_dbg
```
Foundation for being able to bazelify the build artifact -> build
package -> distribtest workflow tests.
Main ideas:
- "build artifact" and "build packages" will be represented by a custom
genrule (that runs the build on RBE under a docker container).
- since genrule doesn't support displaying logs for each target as a
separate "target log" (in the same way that bazel tests do), and we
generally want readable per-target logs for the bazelified test, a pair
of targets will be created for each "build artifact task":
- a genrule that actually performs the build, creates an archive with
artifacts and stores the exitcode and build log as rule outputs
- a corresponding "build_test" sh_test that simply looks at the result
of the genrule and presents the build log and build result a "target
log" for this test.
Bumping gcc 7 to 8 to workaround the ongoing gcc segfault problem when
building Protobuf C++. Currently Foundational C++ requires gcc 7 so this
is a temporary measure to make the test green. We need to either make a
decision to change the minimum version of gcc in the Foundational C++ or
find a way to support gcc 7 without gcc segfault soon.
Support Python 3.12.
### Testing
* Passed all Distribution Tests.
* Also tested locally by installing 3.12 artifact.

Bazelify tests from "linux/grpc_bazel_build" kokoro job by creating 3
bazelified tests - "build with strict warning", "build with no_xds=True"
and "build with no_xds=True negative test".
- also make the original "linux/grpc_bazel_build" kokoro job a no-op
(since bazelified tests now provide the same coverage).
- make C-core basictests use `--build_only` when running as bazelified
tests. This is because the volume of C core tests is expected to grow
very significantly after https://github.com/grpc/grpc/pull/34419 and
currently the non-bazelified counterpart of the tests (the presubmit
grpc_basictests_c_cpp_build_only job) is also "build only".
- make the linux presubmit job `grpc_basictests_c_cpp_build_only` a
noop, since the bazelified tests already give the same coverage on
presubmit.
1. Switch to CMake 1.18.
2. Make ergonomic change to push_testing_images.sh to allow building
just a single image.
3. Update packages to reduce a number of vulnerabilities reported.
Basically run each of the subtests (buildtest, distribtest_cpp,
distribtest_python) as a separate bazel target.
- currently the bazel distribtest are the slowest targets in
grpc_bazel_rbe_nonbazel
- the shards are basically independent tests anyway
- when split into multiple targets, they each get a separate target log
so it's easier debug issues since there isn't multiple bazel invocations
in each log.
- Upgrade bazel
- Reduce the number of places where bazel version needs to be upgraded
in future.
- also make sure the list of bazel versions to test by bazelified tests
is loaded from supported_versions.txt (it was hardcoded before).
- ~~Try upgrading windows RBE build to bazel 6.3.2 as well.~~
The core idea:
- the source of truth for supported bazel versions is in
`bazel/supported_versions.txt`
- the first version listed in `bazel/supported_versions.txt` is
considered to be the "primary" bazel version and is going to be used in
most places thoroughout the repo.
- use templates to include the primary bazel version in testing
dockerfiles and in a newly introduced `.bazelversion` files (which gets
loaded by our existing `tools/bazel` wrapper).
~~Supersedes https://github.com/grpc/grpc/pull/33880~~
Needs https://github.com/grpc/grpc/pull/34035 to be merged first. With
newer ccache in available in the gcc12 test image, the build is now
faster so we can reenable the test.
Based on https://github.com/grpc/grpc/pull/34033
Bunch of cleanup and rebuilding many docker images from scratch
- consolidate the workaround for "dubious ownership" issue reported by
git. Other team members have run into this recently and used similar but
not identical workarounds so some cleanup is due.
- rebuilding many images increases the chance that we fix the "dubious
ownership" git issue early on rather than later on in the one-at-a-time
fashion in the future (and the former will prevent many teammembers from
wasting time on this weird issue).
- Newer version of ccache is needed for some portability tests to be
able to benefit from caching (e.g. the GCC 12 portability test to get
benefits of local disk caching) - this is a prerequisite for reenabling
the bazelified gcc12 portability test.
- upgrade node interop images to debian:11 (since debian jessie is long
past EOL).
Reintroduce https://github.com/grpc/grpc/pull/33959.
I added a fix for the python arm64 build (which is the reason why the
change has been reverted earlier).
- some cleanup
- add bazel distribtests (to run the existing
test_single_bazel_version.sh locally under a docker container created by
RBE).
- add c++ distribtests
- rename `grpc_run_tests_py_test` macro to `grpc_run_tests_harness_test`
- as requested previously to avoid confusion with `*_py_test` rules
Add "bazelified" non-bazel tests. See tools/bazelify_tests/README.md for
the core idea.
- add a bunch of test targets that run under docker and execute tests
that correspond to `run_tests.py -l LANG ...`
- many more tests can be added in the future
- to enable running some of the C/C++ portability tests easily, added
support for `--cmake_extra_configure_args` in run_tests.py (the change
is fairly small).
