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

问题描述

一次 git commit 可能会更改一些工作空间规则、一些源文件、.bazelrc 等。如何让所有 Bazel 目标受到影响，因此需要在更改后重新构建和测试？

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

解决方案

见这里：

# 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。
