ruby -v: ruby 2.7.0p0 (2019-12-25 revision 647ee6f091) [s390x-linux]
Since the default timeout is 10s, I tried to increase the timeout to 30s via simple sed -i '/assert_in_out_err/ s/)/, timeout: 30)/' test/-ext-/bug_reporter/test_bug_reporter.rb and this seems to help to avoid this issue.
However, I am not really sure why s390x is so slow handling this test case :/

Updated by jaruga (Jun Aruga) almost 5 years ago
Note seeing Travis's latest 5 s390x jobs, the s390x jobs have done successfully.
This error does not happen on Travis s390x case.
https://travis-ci.org/ruby/ruby/branches
Could you attach the reported error log's build.log file?
In this case, the possible steps to debug I think is
- Run only "TestBugReporter#test_bug_reporter_add" case, then check if the error still happens.
- For "1.", the error still happens, use
stracefor the command running only the "TestBugReporter#test_bug_reporter_add" case, and compare the outputted logs between s390x and other architectures. Check if some system calls returns error. - Check the source code with the clues of "2.".

I meant that people might want to compare the build environment between Fedora project's build system and Travis, such as gcc version, the compiler flags, make command options, and etc.
Updated by vo.x (Vit Ondruch) over 4 years ago
- Subject changed from TestBugReporter#test_bug_reporter_add test failures on s390x to TestBugReporter#test_bug_reporter_add test failures
Digging a bit into this issue, I was wrong that this is just s390x.

I also triggered this on i686 after 607 iterations. So can somebody please help to address this?
Updated by vo.x (Vit Ondruch) over 4 years ago
So I did quite a lot of testing focusing especially on internals of EnvUtils.invoke_ruby and I am not sure if there is a fix. It seems that especially the s390x build cluster is sometimes under heavy load. I extended the timeout and so far the test was executed in the more then 56 seconds for the worst case. I am afraid that even 60 seconds timeout would not be enough in some case.
Therefore I wonder if there is any other possible solution?
For example I have tried for the process to exit prior waiting for the threads to join, but I don't think I see any difference.
Now I am going to test with the disabled timeout error, because it seems to me that the output consumed from the stdout/stderr contains the expected content, just the threads/process does not exit in time.
Last option could be to repeat the test several times until it succeeds. It does not look that the worst cases happens one after another, although there might be periods of time when the situation is worse.

I took a look at the code.
RUBY_TEST_TIMEOUT_SCALE=5 \
make runruby TESTRUN_SCRIPT="-Itool/lib test/-ext-/bug_reporter/test_bug_reporter.rb -v"
test/-ext-/bug_reporter/test_bug_reporter.rb calling
tool/lib/test/unit/core_assertions.rb#assert_in_out_err calling
tool/lib/envutil.rb#invoke_ruby.
https://github.com/ruby/ruby/blob/098e8c2873ed7cfa276aa87967ce28ac711cbb30/tool/lib/envutil.rb#L166
def invoke_ruby(args, stdin_data = "", capture_stdout = false, capture_stderr = false,
encoding: nil, timeout: 10, reprieve: 1, timeout_error: Timeout::Error,
stdout_filter: nil, stderr_filter: nil,
signal: :TERM,
rubybin: EnvUtil.rubybin, precommand: nil,
**opt)
timeout = apply_timeout_scale(timeout)
...
if (!th_stdout || th_stdout.join(timeout)) && (!th_stderr || th_stderr.join(timeout))
timeout_error = nil
else
# <= If the error will happen, above `th_stdout.join(timeout)` or `th_stderr.join(timeout)` returning `nil`, entering this line.
status = terminate(pid, signal, opt[:pgroup], reprieve)
terminated = Time.now
end
...
if timeout_error
# <= The error will happen when entering this line.
bt = caller_locations
msg = "execution of #{bt.shift.label} expired timeout (#{timeout} sec)"
msg = failure_description(status, terminated, msg, [stdout, stderr].join("\n"))
raise timeout_error, msg, bt.map(&:to_s)
end
...
So, I could reproduce this error always on my local by setting small value to the scale like 0.01.
$ RUBY_TEST_TIMEOUT_SCALE=0.01 make runruby TESTRUN_SCRIPT="-Itool/lib test/-ext-/bug_reporter/test_bug_reporter.rb -v"
I extended the timeout and so far the test was executed in the more then 56 seconds for the worst case. I am afraid that even 60 seconds timeout would not be enough in some case.
I would like to find the way to rescue the long running case improving the logic in the invoke_ruby.

How about just running the tests with large timeout number? For example when setting RUBY_TEST_TIMEOUT_SCALE=100, the actual timeout is 1000 (10 * 100) seconds. It's good enough for the "more then 56 seconds", right?
RUBY_TEST_TIMEOUT_SCALE=100 \
make runruby TESTRUN_SCRIPT="-Itool/lib test/-ext-/bug_reporter/test_bug_reporter.rb -v"
def invoke_ruby(args, stdin_data = "", capture_stdout = false, capture_stderr = false,
encoding: nil, timeout: 10, reprieve: 1, timeout_error: Timeout::Error,
stdout_filter: nil, stderr_filter: nil,
signal: :TERM,
rubybin: EnvUtil.rubybin, precommand: nil,
**opt)
# timeout => 10 seconds
timeout = apply_timeout_scale(timeout)
# timeout => 1000 seconds

Therefore I wonder if there is any other possible solution?
Another option might be using --retry with jobs.
https://github.com/ruby/ruby/blob/098e8c2873ed7cfa276aa87967ce28ac711cbb30/tool/lib/test/unit.rb#L194
But it seems it does not retry the test when having a error in it. Maybe it reties only when having a failure.
$ make test-all TESTOPTS="-n test_bug_reporter_add --timeout-scale=0.01 --retry --jobs=3"

After a lot of testing, I think that the test should not fail with the timeout, because the input for the asserts is collected quite early and the system just does not have time to finish the threads and the child process. Since we don't want to test the system, but only the Ruby, I think the timeout should be just ignored. Please see the attached patch.
And just for illustration, even though the threads are timeouted, it still can take long seconds to finish the test case, because the test waits for the process exit status status ||= Process.wait2(pid)[1] and it might take a while. Attaching graph of the 10000 iterations of the test and the time it takes to finish the test despite the timeout is ignored.

Can anybody please take a look. I think this patch works just fine on Fedora.

Note I am planing to check this ticket after reviving Travis s390x (#17818).
Updated by jaruga (Jun Aruga) over 3 years ago
I would just share my update for this ticket. I wanted to check this ticket after fixing another issue #18002 that is needed to print the result of the Ubuntu s390x on rubyci.org. However I may check it in parallel.

Perhaps this issue is relevant with #17052 .
Updated by xtkoba (Tee KOBAYASHI) about 3 years ago
What I noticed in the description is that "C level backtrace information" is not shown, which suggests that the functions in addr2line.c are never called from rb_vm_bugreport (or its offspring). Thus I suppose #17052 is irrelevant to this.
There is another issue as to why C backtrace does not appear. It is true that we can configure so that it does not, but by default it should on GNU/Linux using glibc.

- Status changed from Open to Closed
I checked all recent ruby-master failures in the RHEL 7.1 s390 CI (http://rubyci.s3.amazonaws.com/rhel_zlinux/ruby-master/recent.html), and none show this issue. Considering this error was occuring in 90% of cases, since it hasn't happened recently, I assume this has been fixed. If you are still seeing this error with current Ruby, please reply and we can reopen.

I'm going to drop the patch testing with Ruby 3.3. Just briefly looking at the changes of the test case, I can imagine this one git|308fe1eb858fd8029f67510a18 could have positive influence. But not sure, because I'd say this must have been issue also for Ruby 3.2. I'll see and will be back if I observe some issues.
