[Bug 1188850] Re: cgrulesengd cannot process symlinked executables
Hello ojab, or anyone else affected, Accepted libcgroup into precise-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/libcgroup/0.37.1-1ubuntu10.1 in a few hours, and then in the -proposed repository. Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .

Thanks, ojab - tried out your testcase, worked like a charm. (For manual reproduction, I'd recommend sleeping 20 rather than 2) ** Description changed: Oh hai!

[Bug 1188850] Re: cgrulesengd cannot process symlinked executables
Sorry for delay, simple testcase:
sudo cgcreate -g memory:/
sudo cgcreate -g memory:/test
echo `whoami`:python2.7 memory test/ | sudo tee -a /etc/cgrules.conf
/usr/bin/env python -c import time; time.sleep(2)
export PID=$!
sudo cgclassify $PID
grep $PID /sys/fs/cgroup/memory/{,*/}cgroup.procs
In case of fixed libcgroup output will be something like
/sys/fs/cgroup/memory/test/cgroup.procs:5778
Right now it is
Error in determining process name of pid 2042
/sys/fs/cgroup/memory/sysdefault/cgroup.procs:2042

[Bug 1188850] Re: cgrulesengd cannot process symlinked executables
Thanks for reporting this bug and pointing to the nice simple fix. Ill work on SRUing this. Would you mind adding a detailed test case to the description? (The symlinking part is fine, but the configuration file plus a neat way to determine that the task failed to be reclassified.) ** Changed in: libcgroup (Ubuntu) Status: Confirmed = Fix Released ** Changed in: libcgroup (Ubuntu) Importance: Wishlist = High -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to libcgroup in Ubuntu. https://bugs.launchpad.net/bugs/1188850 Title: cgrulesengd cannot process symlinked executables To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libcgroup/+bug/1188850/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
