Here, `*_test.cpp` already removes the integration-test sources before `*/test/*` can match them, and `*/testing/*` removes the testing mocks before `*mock*` can match them. With a synthetic trace containing project sources, dependencies, unit/integration tests, helpers, and mocks, this exact command exits with code 25: `lcov: ERROR: 'exclude' pattern '*/test/*' is unused.` Because the script uses `set -e`, it stops before replacing `coverage.info` or generating HTML. Please make unused patterns nonfatal for this filtering step (for example, with `--ignore-errors unused` on LCOV 2.x). ########## test/generate_coverage.sh: ########## @@ -20,10 +20,25 @@ set -e cd $(dirname "$0")/../ mkdir -p build && cd build -cmake ../ -DCMAKE_BUILD_TYPE=Debug -DPAIMON_BUILD_TESTS=ON -DPAIMON_USE_ASAN=ON -DPAIMON_GENERATE_COVERAGE=ON -DCMAKE_EXPORT_COMPILE_COMMANDS=ON +cmake ../ -DCMAKE_BUILD_TYPE=Debug -DPAIMON_BUILD_TESTS=ON -DPAIMON_USE_ASAN=ON -DPAIMON_GENERATE_COVERAGE=ON -DCMAKE_EXPORT_COMPILE_COMMANDS=ON \ + -DPAIMON_ENABLE_AVRO=ON -DPAIMON_ENABLE_ORC=ON \ + -DPAIMON_ENABLE_MOSAIC=ON -DPAIMON_ENABLE_LANCE=ON -DPAIMON_ENABLE_VORTEX=ON make -j make test lcov --capture --directory src/paimon --directory test --output-file coverage.info +# Keep only project implementation code in the report: drop system headers, +# third-party dependencies from the build tree and third_party/, and test +# sources (*_test.cpp, test helpers, mocks). +lcov --remove coverage.info \ + '/usr/*' \ + '*/build*/*' \ Review Comment: **Anchor the build exclusion to the actual build directory**: This wildcard matches any ancestor directory beginning with `build`, including a checkout at `/builds/paimon-cpp` or `/home/builder/paimon-cpp`. Consequently, it also removes legitimate records such as `/builds/paimon-cpp/src/paimon/status.cpp` and `/builds/paimon-cpp/include/paimon/result.h`. I reproduced an empty-trace failure with the former layout, even after ignoring unused-pattern errors. Please scope this exclusion to the absolute build directory, or positively extract the absolute `src/paimon` and `include/paimon` roots before excluding test sources. -- This is an automated message from the Apache Git Service.
