Using calloc() instead of malloc() as preventive measure, so there never can be any hidden bugs or leaks due uninitialized memory. The extra cost of using this compiler intrinsic should be practically impossible to measure - in many cases a good compiler can even deduce if certain areas really don't need to be zero'd (because they're written to right after allocation) and create more efficient machine code. The code pathes in question are pretty cold anyways, so it's probably not worth even thinking about potential extra runtime costs. Signed-off-by: Enrico Weigelt, metux IT consult <info@metux.net>
X server test suite This suite contains a set of tests to verify the behaviour of functions used internally to the server. = How it works = Through some automake abuse, we link the test programs with the same static libraries as the Xorg binary. The test suites can then call various functions and verify their behaviour - without the need to start the server or connect clients. This testing only works for functions that do not rely on a particular state of the X server. Unless the test suite replicates the expected state, which may be difficult. = How to run the tests = Run "make check" in the test directory. This will compile the tests and execute them in the order specified in the TESTS variable in test/Makefile.am. Each set of tests related to a subsystem are available as a binary that can be executed directly. For example, run "xkb" to perform some xkb-related tests. == Adding a new test == When adding a new test, ensure that you add a short description of what the test does and what the expected outcome is.
