RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Edjunior Barbosa Machado 2019-01-08 16:23:08 UTC 
Description of problem:
Several debuginfo-both testcases from rust-1.31.0-5.module+el8+2556+ac3e4365 internal testsuite are failing on RHEL-8 x86_64 and aarch64. Most of these tests are either running successfully or being ignored on ppc64le and s390x. The total of failures on debuginfo-both testcases by arch are:

aarch64: 91
x86_64: 93
ppc64le: 7
s390x: 8

This is the list of failures on x86_64:

These are all new testcases that were not included in previous rust-1.29.2-1.module+el8+2183+c73ca3a4.

Version-Release number of selected component (if applicable):

Steps to Reproduce:

2. rpmbuild --recompile ./rust-1.31.0-5.module+el8+2556+ac3e4365.src.rpm
Comment 2 Edjunior Barbosa Machado 2019-01-08 16:28:20 UTC 
Most of the failures seem to be related to this python error when trying to import thread module (deprecated on python3):

And the reason they are not failing in s390x and ppc64le might be because these arches currently do not support lldb.
Comment 3 Josh Stone 2019-01-08 21:28:00 UTC 
I've sent a PR to use _thread as a fallback: https://github.com/rust-lang/rust/pull/57453

I don't think this is critical for GA.  In the meantime, if you can run the testsuite on a machine *without* LLDB installed, you should at least be able to get GDB results.

Without lldb installed on these arches, the number of failures on debuginfo-both testcases was strongly reduced:

aarch64: 8

Comment 5 Josh Stone 2019-01-15 17:23:27 UTC 
Thanks. And the upstream patch was merged to fix rust-lldb for python3.

I think the enum failures are just small differences in the way they are printed by different versions of GDB.

This is a recurrence of bug 1611597, llvm bug 1625768. That patch didn't make it into the LLVM 7 release, and was forgotten to backport in the RHEL8 package. It's just a debuginfo issue though, not affecting program execution, so I don't think it's critical.
Comment 9 Alexandra Petlanová Hájková 2019-07-16 11:32:21 UTC 
According to the testsuite results this bug does not seem to be fixed, the full results: http://plat-qe-04.lab.eng.rdu2.redhat.com/output.html

Comment 11 Josh Stone 2019-07-16 20:02:51 UTC 
Hmm, strange, it's a different error, but for some reason the testsuite is trying to use python2.7.

error: Error while running LLDB

The compiletest command for this section has "--lldb-python" "/usr/bin/python2.7" ... "--lldb-python-dir" "/usr/lib64/python3.6/site-packages". It's not going to work to mix python versions, of course.

The brew build used platform-python here, for a consistent python3 experience. But lldb wasn't installed either, so it only actually ran gdb tests.

Maybe it will work as expected if python2.7 is not installed on your test machine? But there may be some configuration flag I can set to make sure the desired python is used everywhere, not left to some fickle detection.

So yes, I found this in src/bootstrap/sanity.rs:

    build.config.python = build.config.python.take().map(|p| cmd_finder.must_have(p))
        .or_else(|| cmd_finder.maybe_have("python2.7"))
        .or_else(|| cmd_finder.maybe_have("python2"))
        .or_else(|| env::var_os("BOOTSTRAP_PYTHON").map(PathBuf::from)) // set by bootstrap.py
        .or_else(|| Some(cmd_finder.must_have("python")));

That is, use the "./configure --python" value if given, otherwise try python2.7, python2, BOOTSTRAP_PYTHON (the one running the build script), or just python. I wasn't setting the configure option before, and in brew I didn't have any python2 installed, so it used BOOTSTRAP_PYTHON. But I guess your system did have python2.7, so that was chosen.

I will set "./configure --python" in the next build.
