# Basic isolation test for injection points. # # This checks the interactions between wakeup, wait and detach. # Feel free to use it as a template when implementing an isolation # test with injection points. setup { CREATE EXTENSION injection_points; } teardown { DROP EXTENSION injection_points; } # Wait happens in the first session, wakeup in the second session. session s1 setup { SELECT injection_points_set_local(); SELECT injection_points_attach('injection-points-wait', 'wait'); } step wait1 { SELECT injection_points_run('injection-points-wait'); } step noop1 { } session s2 step wakeup2 { SELECT injection_points_wakeup('injection-points-wait'); } step detach2 { SELECT injection_points_detach('injection-points-wait'); } # Detach after wait and wakeup. Note that the detach may finish before # the SQL function doing the wait returns its result. In order to avoid # any ordering issues, a no-op step is added after the wait, so as the # detach is not launched until the wait has completed. permutation wait1 wakeup2 noop1 detach2 # Detach before wakeup. s1 waits until wakeup, ignores the detach. permutation wait1 detach2 wakeup2 # Detach before wait does not cause a wait, wakeup produces an error. permutation detach2 wait1 wakeup2
