Red Hat Bugzilla – Bug 834257
sym comand should print '0x' prefix before printing the actual value
Last modified: 2013-03-03 20:35:17 EST
Description of problem: sym command should print 0x prefix before the hex address, so the output could be directly passed to px command if neccessary. Version-Release number of selected component (if applicable): # rpm -qf /usr/bin/crash crash-5.1.8-1.el6.x86_64 megatron$ rpm -qf `which crash` crash-6.0.5-0.x86_64 How reproducible: Always Steps to Reproduce: 1. sym schedule 2. 3. Actual results: crash> sym schedule ffffffff800623d0 (T) schedule ../debug/kernel-2.6.18/linux-2.6.18-308.el5.x86_64/kernel/sched.c: 3520 Expected results: crash> sym schedule 0xffffffff800623d0 (T) schedule ../debug/kernel-2.6.18/linux-2.6.18-308.el5.x86_64/kernel/sched.c: 3520 Additional info:
Sorry, no, that's not going to happen. A foundational tenet of the crash utility is the avoidance of the 0x whenever possible, both for user input and command output. Now, I would consider adding an option to the "sym" command that would pre-pend the 0x.

There's no "crash utility team" -- there's me, plus an active community that I lead on the crash-utility@redhat.com mailing list. Patches are posted there regularly and other discussions held, but I am the gate-keeper since I wrote the thing from scratch many years ago. I typically release a new upstream version once-a-month. I do have some architecture sub-maintainers for ARM, S390X and PPC64, who handle some of the more machine-specific stuff.
