#You Only Leak Once

# Install valgrind using one of the following
brew install valgrind
sudo apt-get install vagrind

# make sure valgrind is enabled in your ruby build
CONFIGURE_OPTS="--with-valgrind" rbenv install 2.0.0-p0

# control test (should not show any memory leaks)
valgrind --leak-check=full -v ruby -e "puts 'yolo'"

# one of our unit tests (takes a lot longer than running the test normally)
valgrind --trace-children=yes --leak-check=full -v ruby -Ilib:test test/unit/publisher_test.rb
