Short summary: have "-debug" terminating your branch name. See: https://github.com/ceph/ceph-build/pull/2167 and the integration branch helper script change: https://github.com/ceph/ceph/pull/53855 The benefit for doing this is that mutex debugging will be enabled, many compiler checks are enabled, and some optimizations will be disabled (potentially making some debugging easier). One known drawback will be that execution may be slower. See also: https://github.com/ceph/ceph-build/pull/2167#issuecomment-1751033910 There are build failures for CentOS 8 for which I will make tickets soon. See also: https://shaman.ceph.com/builds/ceph/wip-batrick-testing-20231006.014828-deb… If this is shown to not create a lot of fallout in the QA suite testing, this may be turned on by default without the "-debug" suffix on branch names. I encourage QA testers to give this a try so any issues can be shaken out. -- Patrick Donnelly, Ph.D. He / Him / His Red Hat Partner Engineer IBM, Inc. GPG: 19F28A586F808C2402351B93C3301A3E258DD79D
