Valgrind

Valgrind

Valgrind is useful for performing dynamic analysis. Valgrind tools can automatically detect many memory management and threading bugs, and profile Peloton in detail.

Memory Leaks

Here's the command for using memcheck for detecting common memory errors.

valgrind --trace-children=yes --track-origins=yes peloton -D ./data

valgrind --trace-children=yes --track-origins=yes ./test/catalog_test

Profiling

Here's the command for using callgrind for profiling Peloton.

    valgrind --tool=callgrind --trace-children=yes ./src/peloton -D data &> /dev/null &

    pg_ctl -D ./data stop

You can use kcachegrind for viewing the collected profile files (i.e. the callgrind.out.* files).
