<html><body><p>I've never seen this test fail before. We haven't changed the kqueue git submodule version since July 20. It looks like the next 20 runs of this CI build didn't hit this test failure either. <br><br>I took a quick scan of the kqueue tests and like some of the other libdispatch test cases, the kqueue test is not bulletproof if the system on which it is run is under very unusual load. For example, there are tests of timer events and if the expected timers are more than a second late, the testcase is marked as a failure. Fairly reasonable for a testcase run on a development machine before committing code. Not great for running hundreds of times in a less controlled environment. We will get occasional spurious failures. <br><br>As part of getting the dispatch tests running in the CI environment, we've turned off about 20% of the test cases because they were having non-reproducible occasional failures on the CI machines. This probably ties back to the discussion a few days ago on this list about the lldb tests. What's the best way for us to structure testcases that test end-to-end properties or timeliness expectations for highly concurrent code that won't cause unacceptable levels of spurious failures in the CI environment?<br><br>--dave<br><br><img width="16" height="16" src="cid:1__=0ABB0A89DFD7659C8f9e8a93df938690918c0AB@" border="0" alt="Inactive hide details for "Daniel A.
