---------------------------------------
Summary: Segfault shadows failures in unit tests
Key: CASSANDRA-12957
URL: https://issues.apache.org/jira/browse/CASSANDRA-12957
Project: Cassandra
Issue Type: Bug
Components: Testing
Reporter: Alex Petrov
It looks like a segfaulting VM will shadow the CI results, for example
[here|https://cassci.datastax.com/view/Dev/view/ifesdjeen/job/ifesdjeen-12651-segfault-testall/1/],
I added a test that segfaults.
Some times the tests with
{code}
Forked Java VM exited abnormally. Please note the time in the report does not
reflect the time until the VM exit.
{code}
error messages are disregarded or skipped due to the lack of information.
Although if you look closer in the [full
log|https://cassci.datastax.com/view/Dev/view/ifesdjeen/job/ifesdjeen-12651-segfault-testall/1/consoleFull]
you will see the actual segfault:
{code}
12:51:30 [junit] # A fatal error has been detected by the Java Runtime
Environment:
12:51:30 [junit] #
12:51:30 [junit] # SIGSEGV (0xb) at pc=0x00007f7dac4b9900, pid=12587,
tid=140177756509952
{code}
Test result is {{1 failure}} (which is kind of expected), but this failure
resulted into skip of all the other tests.
Can we track the tests that were skipped not by test runner (reported by
{{Failed: x, Skipped: y}} in test results), but without "intention" (test
runner crash, segfault etc) and maybe add more infos on segfaults (possibly
whole trace)? Might be there are unnoticed segfaults?
