As s_lock_test, the already existing test for spinlocks, isn't run in an automated fashion (and doesn't test a normal backend environment), adding tests that are run as part of a normal regression run is a good idea. Particularly in light of several recent and upcoming spinlock related fixes. Currently the new tests are run as part of the pre-existing test_atomic_ops() test. That perhaps can be quibbled about, but for now seems ok. The only operations that s_lock_test tests but the new tests don't are the detection of a stuck spinlock and S_LOCK_FREE (which is otherwise unused, not implemented on all platforms, and will be removed). This currently contains a test for more than INT_MAX spinlocks (only run with --disable-spinlocks), to ensure the recent commit fixing a bug with more than INT_MAX spinlock initializations is correct. That test is somewhat slow, so we might want to disable it after a few days. It might be worth retiring s_lock_test after this. The added coverage of a stuck spinlock probably isn't worth the added complexity? Author: Andres Freund Discussion: https://postgr.es/m/20200606023103.avzrctgv7476xj7i@alap3.anarazel.de |

PostgreSQL tests ================ This directory contains a variety of test infrastructure as well as some of the tests in PostgreSQL. Not all tests are here -- in particular, there are more in individual contrib/ modules and in src/bin. Not all these tests get run by "make check".
