git - 如何知道受 git commit 影响的所有 Bazel 目标？

Question

git commit 可能会改变一些 workspace rules ，一些源文件，.bazelrc 等。如何让所有 Bazel 目标受到影响，从而需要在此类更改后重建和测试？

在 Buck 中，我们可以运行 buck targets --show-rulekey //...查看两个 Git 修订版之间的所有规则键更改。 Bazel 中是否有任何等效的命令？

见 here :

# Under Apache 2.0 licence
COMMIT_RANGE=${COMMIT_RANGE:-$(git merge-base origin/master HEAD)".."}

# Go to the root of the repo
cd "$(git rev-parse --show-toplevel)"

# Get a list of the current files in package form by querying Bazel.
files=()
for file in $(git diff --name-only ${COMMIT_RANGE} ); do
  files+=($(bazel query $file))
  echo $(bazel query $file)
done

# Query for the associated buildables
buildables=$(bazel query \
    --keep_going \
    --noshow_progress \
    "kind(.*_binary, rdeps(//..., set(${files[*]})))")
# Run the tests if there were results
if [[ ! -z $buildables ]]; then
  echo "Building binaries"
  bazel build $buildables
fi

tests=$(bazel query \
    --keep_going \
    --noshow_progress \
    "kind(test, rdeps(//..., set(${files[*]}))) except attr('tags', 'manual', //...)")
# Run the tests if there were results
if [[ ! -z $tests ]]; then
  echo "Running tests"
  bazel test $tests
fi

也看看 bazel-diff .
