modules/protoc_gen_clojure/0.2.0/presubmit.yml

# Platforms are constrained by what the released binaries can actually run on, not
# by what BCR offers.
#
# The test module executes the prebuilt plugin, and the Linux binaries are
# dynamically linked. Their floor is measured rather than assumed: the release
# workflow prints it, and v0.1.0-rc1 reported GLIBC_2.34 on both x86_64 and
# aarch64 — lower than the ubuntu-24.04 runner's own 2.39, because GraalVM links
# against older symbol versions than the build host provides.
#
# ubuntu2204 (glibc 2.35) therefore belongs here: it clears 2.34, and is the oldest
# image BCR offers that does. debian11 (2.31) does not, and would fail with
# "GLIBC_2.34 not found" — a pull request failing its own presubmit. Static linking
# (issue #17) is what would reach back that far.
#
# arm64 is included deliberately: it is the only place the linux_aarch64 and
# darwin_arm64 release assets, and the toolchain's platform selection between them,
# get exercised at all.
#
# bazel is 9.x only. The module has never been built with Bazel 8, and claiming
# support that fails here would block publication rather than merely disappoint.

# The real test: a module that depends on this one, registers the toolchain, and
# generates Clojure from a .proto with no Clojure, JVM or GraalVM of its own. That
# claim is untestable anywhere else, because the toolchain downloads a binary from a
# published release.
