Interesting, Origin had Dwarf at one point and I don't recall anyone removing it. This turned out to be a rpmbuild problem, and if being fixed by this pull request. https://github.com/openshift/origin/pull/6545 Basically we are just adding %global __os_install_post %{_rpmconfigdir}/brp-compress Before it put's everything in it's proper rpm, rpmbuild tries to make things as small as possible. We were already skipping the part where it pulls out the debuginfo (which breaks go packages), but there is another step called brp-strip-static-archive. According to rpmbuild, go binaries are static-archive's, and so it was stripping the debug stuff out of them. Why did origin have dwarf debugging and then it didn't? Origin has always been compiled with the DWARF debugging on. We originally were not packaging origin into rpms. They were either in tarballs, images, or compiled locally. When we started putting it into rpm's was when we started looking the debuginfo. NOTE: How to tell if the binary has dwarf debug in it or not. 1 - Run something that will take some time /usr/bin/oc status # On a non-setup machine, this takes a while to timeout 2 - Find out the process id ps ax | grep status | grep oc 3 - gdb attach to that process and look if it was able to load debuginfo for that process. 3a - No DWARF debugging gdb attach 4237 <snip> Attaching to process 4237 Reading symbols from /usr/bin/oc...(no debugging symbols found)...done. <snip> 3b - DWARF debugging in binary gdb attach 8138 <snip> Attaching to process 8138 Reading symbols from /usr/bin/oc...done. <snip> Verified with atomic-openshift-3.1.1.1-1.git.0.dba03a7.el7aosAttaching to Attaching to process 30758 Reading symbols from /usr/bin/oc...done. I can reproduce this issue with AEP container install RH7.2 env with below version: openshift v3.1.1.3 kubernetes v1.1.0-origin-1107-g4c8e6f4 etcd 2.1.2 Here is the result, so will re-open this bug now: Attaching to process 6456 Reading symbols from /usr/bin/bash...Reading symbols from /usr/bin/bash...(no debugging symbols found)...done. This ticket isn't about /usr/bin/bash, it is about /usr/bin/oc, or any of the binaries that come from openshift. Please re-test against /usr/bin/oc, or /usr/bin/openshift. Thanks, it works now: For container env, oc/openshift binary should be copied out from atomic-openshift-master container: 1. docker cp atomic-openshift-master:/usr/bin/oc ./ 2. ./oc get pods --watch 3. ps-ef | grep oc 4. gdb attach <oc_process_id> Attaching to process 12699 Reading symbols from /root/oc...done.
