Add GitHub Actions CI workflow for unit tests (#379)
* Add unit test for psync_task_free refcount fix (#377) Adds tests/unit-tests/test_ptask_free.c to verify all code paths of the psync_task_free fix from #377: single-owner free, last-ref destroy, non-last-ref decrement, READY task signaling, and lock-before-refcnt ordering. All 5 tests pass. Also adds compiled binary to .gitignore. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * Add GitHub Actions CI workflow for unit tests Triggers on push/PR to automated-testing branch. Installs cmake and build-essential, builds all test targets via cmake, and runs ctest --output-on-failure. Fails workflow on any test failure. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * Replace cmake CI with make tests/check targets Adds tests and check targets to Makefile — no cmake required. Each test binary is built with the correct flags (pthread, -lrt, --wrap linker flags for prun/ptools_errptr). CI workflow installs only build-essential, runs make tests then make check; exits non-zero on any failure. All 8 test suites pass locally. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * Fix CI: install libfuse3-dev so Makefile parses on Ubuntu detect_fuse.sh runs at Makefile parse time; without fuse headers the $(error) fires before any target runs. Adding libfuse3-dev unblocks make tests (test binaries themselves don't link fuse). Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix makefile * Add automated testing infrastructure - Update CI workflow to run unit tests and build verification - Add Makefile targets for test compilation and execution - Implement unit tests for pdbg_path, prun, and read_response - Add test stubs for pCloud API mocking - Add test binaries for pfs_lock_ordering and signal_safety verification * Add missing dependencies to CI workflow Install libfuse-dev and libssl-dev required for build * Add test job to c-cpp.yml workflow Include unit test execution in C/C++ workflow * Add missing stubs to test_stubs.c Complete stub implementations for all required pCloud API functions * Fix stub signatures to match headers Correct function signatures for pCloud API stubs * Fix psql_* stub signatures Correct all psql function signatures to match headers * Fix stub implementations and Makefile Update stub functions and build configuration * Link real utility files instead of stubbing Update Makefile to use actual implementation files for utilities * Complete test framework with all 41 tests passing - Makefile: Add test rules with real dependencies - tests/stubs/test_stubs.c: Minimal stubs for external APIs - tests/stubs/test_stubs_cpp.c: Stubs for C++ test - pclsync/putil.c: Add null check in putil_strdup - pclsync/pdbg.c: Add recursion guard in pdbg_printf * Remove duplicate ci.yml workflow Consolidate CI configuration into c-cpp.yml * Remove compiled test binaries from git - Remove test_pfs_lock_ordering and test_signal_safety binaries - Add tests/test_* to .gitignore to prevent future commits --------- Co-authored-by: Levi Neely <lkn@darkstar.example.net> Co-authored-by: Claude Sonnet 4.6 <noreply@anthropic.com>

|

* The mutex is held during the refcnt check in all paths — the core fix.
