- Add pytest-xdist to the CI Dockerfile (image -> v10).
- Worker-isolate TEST_DATA_DIR (PYTEST_XDIST_WORKER) so concurrent xdist
workers never collide on shared-filesystem fixtures.
- Register a 'ci' marker and tag a fast representative subset of integration
tests (basic TCP, incremental, compression, delete, basis, append).
- ci.yaml: lint + build + unit + the marked subset (-n4) on every PR; the
full integration suite plus sanitizer/fuzz/coverage/valgrind run only on
push to dev/main.
- Integration step runtime drops from ~860s (serial) to ~230s (-n4); the PR
gate lands well under ~3 minutes.
- Build and push fastsync-ci:v8 with lcov, valgrind, clang baked in
- Remove all apt-get install steps from CI (v8 has them pre-installed)
- Fix chunk.c use_metadata=true OOB: add remaining_size guard before
metadata_from_buf reads past the buffer. The bug allowed network-facing
chunk_deserialize to heap-buffer-overflow on crafted inputs.
- Also guard against unsigned underflow on remaining_size - sizeof(int)
Add Tier 1 review automation to catch issues before human review:
- Add cppcheck and clang-format to CI lint job
- Add sanitizer matrix (ASan + TSan) CI job
- Enable -Wextra -Wpedantic -Werror in CI build
- Add SANITIZER and STRICT_WARNINGS CMake options
- Add .clang-format for consistent code style
- Update Dockerfile with cppcheck and clang-format
- Fix sign-compare and unused-parameter warnings for -Werror
