[Bug 1720541] Re: flock does not lock dpkg lock file properly
lockfile from the procmail package will do it. ** Changed in: util-linux (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1720541 Title: flock does not lock dpkg lock file properly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/util-linux/+bug/1720541/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1720541] Re: flock does not lock dpkg lock file properly
flock is used for managing locks from shell script. dpkg uses lock file /var/lib/dpkg/lock, but I can not manage it by flock. What is right tool for the job I want to do then? ** Changed in: util-linux (Ubuntu) Status: Invalid => New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1720541 Title: flock does not lock dpkg lock file properly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/util-linux/+bug/1720541/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

No; what you want to do and what flock is intended to do are different things. You're complaining that you can't use a hammer to screw in a screw. You're using the wrong tool for the job. ** Changed in: util-linux (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1720541 Title: flock does not lock dpkg lock file properly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/util-linux/+bug/1720541/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1720541] Re: flock does not lock dpkg lock file properly
Phillip Susi, I never claimed it did. But I may want to lock the /var/lib/dpkg/lock beforehand, so that system is guaranteed to be unchanged before I launch apt-get in a script. So I think the status change you made, and the justification you gave is invalid. ** Changed in: util-linux (Ubuntu) Status: Invalid => New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1720541 Title: flock does not lock dpkg lock file properly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/util-linux/+bug/1720541/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

dpkg does not use flock(); it uses the lock file /var/lib/dpkg/lock. ** Changed in: util-linux (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1720541 Title: flock does not lock dpkg lock file properly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/util-linux/+bug/1720541/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
