The fact that the 389-ds code works on other architectures does not allow us to draw any conclusions at this point. It really needs to go through a root cause analysis to determine exactly why it is not working correctly. That will in turn tell us if it's the 389-ds code or something in the compiler (or elsewhere) that is the problem.

THe current thinking is there are serious concurrency concerns in the freeipa code which are leading to the failures they were seeing on 32 bit platforms (i686 in particular). To be clear there are concerns in 389-ds code that lead to data corruptions on i686. They aren't seen on other 32-bit platforms Fedora supports according to 389-ds developers. FreeIPA has no choice as 389-ds-base was moved to exclude i686 architecture according to the process defined in Fedora. -- / Alexander Bokovoy ___ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org

389-ds-base and freeipa on 32 bit arches
Greetings gcc maintainers! A FESCo issue[0] has been filed due to the dropping of 389-ds-base and freeipa on 32 bit arches for Fedora 28. This was done without a change request being filed, so FESCo is trying to decide how best to handle it. It seems there are some concerns about whether the C tooling correctly handles some cases for 32-bit arches that led to the decision by the IPA maintainers to drop support for 32-bit. FESCo would like to ask for the GCC maintainers' input on the issue. Thanks in advance for your feedback!
