If problems still persist, please make note of it in this bug report. |
Description of problem: This should be easy to implement, and hopefully not controversial. I will solicit feedback from others on the lists. Request that when running retrace-server-interact <taskid> crash, it would change CWD to a 'scratch' area, then when exiting, return CWD to the current directory where it was invoked. Why? It's very common in the course of core analysis to create temporary files which are output of commands run during the analysis, or supporting files to the analysis (such as small scripts). It would be good if once you run 'retrace-server-interact <task> crash' it would change the directory to a scratch area for that core (for now, we can use the 'misc' subdirectory off of the task directory). It should facilitate sharing of information about the vmcore analysis and keep all the files in one place associated with the vmcore. When the task is later removed, all these files can be cleaned up as well. Version-Release number of selected component (if applicable): retrace-server-1.9-6.el6.noarch How reproducible: Every time. Steps to Reproduce: $ retrace-server-interact 404564956 crash crash> ^Z [1]+ Stopped retrace-server-interact 404564956 crash [dwysocha@optimus ~]$ pwd /home/rdu/dwysocha Ideally CWD would be here: [dwysocha@optimus ~]$ cd /cores/retrace/tasks/404564956/misc [dwysocha@optimus misc]$ pwd /cores/retrace/tasks/404564956/misc Here's an example of a command we might want to run. Note I have to put the full path in there, or remember the 'cd /cores/retrace/tasks/404564956/misc' before issuing retrace-server-interact. Otherwise, I have to do this inside crash: crash> ps | grep \> | awk '{ print "bt "$2 }' > /cores/retrace/tasks/404564956/misc/bt-running.crash crash> < /cores/retrace/tasks/404564956/misc/bt-running.crash > /cores/retrace/tasks/404564956/misc/bt-running.txt I'd like to be able to do crash> ps | grep \> | awk '{ print "bt "$2 }' > ./bt-running.crash crash> < ./bt-running.crash > ./bt-running.txt Actual results: Running retrace-server-interact does not change CWD but the location of the scratch area may be a long path. Expected results: retrace-server-interact should change CWD to a scratch area so writing temporary files is easier. Additional info: I tried to think of downsides of changing the directory but did not come up with much. It may not be expected to people that running the command would change CWD into a 'scratch' area for the vmcore, but I'm not sure how much people would care.
