Description

Building Ruby packages on Fedora, in 90% of cases, I observe the following error on s390:

  1) Error:
TestBugReporter#test_bug_reporter_add:
Timeout::Error: execution of assert_in_out_err expired timeout (10 sec)
pid 2061293 killed by SIGKILL (signal 9)

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 :/

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

  1. Run only "TestBugReporter#test_bug_reporter_add" case, then check if the error still happens.
  2. For "1.", the error still happens, use strace for 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.
  3. 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.
