All the fails are common and have the following structure:
-- enabling the error injection
errinj.set("ERRINJ_VY_RUN_WRITE", true);
num_rows = num_rows + range();
-- fails due to error injection
box.snapshot();
-- disabling the error injection
errinj.set("ERRINJ_VY_RUN_WRITE", false);
fiber.sleep(0.06);
num_rows = num_rows + range();
-- FAILS HERE: still fails at the error injection, but in real should pass
box.snapshot();
Steps to reproduce:
l=0 ; while time ./test-run.py -j15 `for r in {1..15} ; do echo vinyl ; done` 2>/dev/null ; do l=$(($l+1)) ; echo ======== $l ============= ; done
l=0 ; while time ./test-run.py -j10 `for r in {1..150} ; do echo vinyl/errinj.test.lua ; done` 2>/dev/null ; do l=$(($l+1)) ; echo ======== $l ============= ; done
Optional (but very desirable):
- coredump
- backtrace
- netstat
