This commit adds tooling to measure how many branches the random simulation
reaches during execution, which helps understand code coverage and identify
untested code paths.
Changes:
- Add coverage build target to Makefile with --coverage flags
- Create measure_coverage.sh script to build, run, and report branch coverage
- Add signal handlers (SIGINT/SIGTERM) to main_test.c for clean shutdown
- Update clean target to remove coverage files (*.gcda, *.gcno)
The script runs the simulation for a specified duration (default 5 seconds),
then uses gcov to analyze which branches were executed. In a 3-second run,
the simulation reaches approximately 32% of all branches (781/2431).
Usage:
./measure_coverage.sh [duration_in_seconds]
Example output shows per-file and total branch coverage statistics.
- Add CLIENT_CFILES and CLIENT_OFILES variables to Makefile
- Add rules to build object files and create static library
- Include libmousefs_client.a in the 'all' target
- Update clean target to remove library and object files
- Update .gitignore to ignore *.o and *.a build artifacts
The library includes: client.c, basic.c, tcp.c, message.c
