[Bug 1446982] Re: Wrong kill mode on shutdown
This does seem to be a systemd problem that is affecting a lot of different applications -- basically any application that would like a SIGTERM on reboot/shutdown so that it can save or clean up resources gracefully. See https://bugzilla.redhat.com/show_bug.cgi?id=1141137 (upstream systemd issue) https://bugzilla.redhat.com/show_bug.cgi?id=1170765 (systemd issue affecting bash's attempt to save history) https://github.com/cockpit-project/cockpit/issues/1155 (systemd issue affecting cockpit) http://lists.freedesktop.org/archives/systemd- devel/2014-October/024452.html (discussion) My suggestion would be that you open a new bug report against systemd in Ubuntu 15.04 and mention that it is affecting bash and mosh (and probably every other application that would like to clean up gracefully on shutdown or reboot). ** Bug watch added: Red Hat Bugzilla #1141137 https://bugzilla.redhat.com/show_bug.cgi?id=1141137 ** Bug watch added: Red Hat Bugzilla #1170765 https://bugzilla.redhat.com/show_bug.cgi?id=1170765 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1446982 Title: Wrong kill mode on shutdown To manage notifications about this bug go to: https://bugs.launchpad.net/mosh/+bug/1446982/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1446982] Re: Wrong kill mode on shutdown
Unfortunately strace didn't reveal much. However, I created a small program to show the signal. Using test.c I can see that when testing with Ubuntu 14.10 the program always creates the "testing.txt" file on restart. However, if I test with Ubuntu 15.04, that file is never created in the same use case. Contrary to my previous claim, it behaves the same way in reboot & shutdown: Mosh gets the error on reconnect and "test.c" never creates the testing.txt file. SIGTERM is never received. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1446982 Title: Wrong kill mode on shutdown To manage notifications about this bug go to: https://bugs.launchpad.net/mosh/+bug/1446982/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Olli, Mosh is in the universe repository, so that responsibility falls to the community. In practice, the set of people working on Mosh in Ubuntu consists of Keith, who is both the upstream maintainer and the maintainer of the Debian package that Ubuntu automatically imports. He knows what he’s talking about, and you should pay attention to his comments. The process of getting volunteers interested in spending their spare time to fix your bug is not always easy, but Keith has suggested a clear path forward, and the ball is in your court now. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1446982 Title: Wrong kill mode on shutdown To manage notifications about this bug go to: https://bugs.launchpad.net/mosh/+bug/1446982/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1446982] Re: Wrong kill mode on shutdown
I'm trying to help you out here, but you are making things more confusing than necessary. If you can document clearly that Ubuntu 15.04 behaves differently from 14.10 in the shutdown sequence (e.g., perhaps Ubuntu 14.10's shutdown sequence sent a SIGTERM *before* cutting off the network, and Ubuntu 15.04 cuts off the network first), you might be able to get the systemd people interested again. But you have to document it very clearly and change only one thing at a time. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1446982 Title: Wrong kill mode on shutdown To manage notifications about this bug go to: https://bugs.launchpad.net/mosh/+bug/1446982/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

(1) I am connecting from a machine running Ubuntu release 15.04 (mosh version 1.2.4a) to one Raspberry Pi machine running Raspbian Wheezy release (mosh version 1.2.3). After shutdown and restart of the machine running Ubuntu release 15.04 (mosh version 1.2.4a) I get this error from the Raspberry Pi machine after a reconnect with mosh from the same 15.04 machine (mosh version 1.2.4a). After restart I do *not* get the this error from the Raspbian machine (mosh version 1.2.3) when doing a reconnect with mosh (version 1.2.4a).

[Bug 1446982] Re: Wrong kill mode on shutdown
Can you be a lot more explicit? To make sure I understand you correctly, you are saying that: (1) With a client running Ubuntu 15.04, shutting down the system does not cleanly close your Mosh connections (it leaves a mosh-server running), but rebooting the system *does* cleanly close your Mosh connections. (2) With a client running Ubuntu 14.10 but nothing else changed, BOTH shutting down AND rebooting the client cleanly close your Mosh connections.

[Bug 1446982] Re: Wrong kill mode on shutdown
My "kill -9" was a description of similar end result as to what happens on shutdown. Mosh behaves the same way. I'm not normally using "kill" directly, I just wish it behaves the same way on reboot and shutdown (i.e. normal kill). I don't even know is there "kill" (SIGTERM) done to mosh on shutdown. This was just a guess. Another option is that it's missing. I read somewhere that at least BSD /sbin/shutdown tries to first kill with SIGTERM and after that with SIGKILL. I don't actually know what the behavior should be on Ubuntu 15.04. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1446982 Title: Wrong kill mode on shutdown To manage notifications about this bug go to: https://bugs.launchpad.net/mosh/+bug/1446982/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1446982] Re: Wrong kill mode on shutdown
Hello, I think this is working as intended. When you "kill -9", that is sending the SIGKILL signal -- you are asking the program to shut down *uncleanly* and immediately. The mosh-client dies immediately, and it doesn't have a chance to let the server know that it won't be coming back. The server has no way to distinguish this from a case where the client simply lost its network connection (but might regain it later). Please use a nicer signal to kill the mosh-client. (E.g. the default for "kill", or just exit from within the client.) Then it will have a chance to shut down the connection cleanly. (You might still have the problem if you exit the client while it doesn't have a network connection -- then it again doesn't have a chance to let the server know that it's quitting. But that is a different problem that is hard to escape given mosh's design of everlasting, roamable connections.) ** Changed in: mosh (Ubuntu) Assignee: (unassigned) => Keith Winstein (keithw) ** Also affects: mosh Importance: Undecided Status: New ** Changed in: mosh Assignee: (unassigned) => Keith Winstein (keithw) ** Changed in: mosh (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/1446982 Title: Wrong kill mode on shutdown To manage notifications about this bug go to: https://bugs.launchpad.net/mosh/+bug/1446982/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
