Public bug reported:
When using adt-virt-qemu to run a script that is larger than ~4215 bytes on a qemu image, the script fails to start execution and a timeout occurs. This behaviour was observed when attempting to unpack a large list of deb files when running the qemu with ro-apt setup-command. A full test log is shown at [1]. For smaller scripts it works fine. But when the script size is about 4215 bytes or more it will start to timeout and fail. I've tried bulking out a smaller script with comment lines to confirm the problem is related to the size of the script, rather than the commands in the script. I've also checked that the number of bytes returned by the socket.send() at [2] is correct to confirm it is sending the whole script. Simple steps to reproduce: $ python -c 'print "echo " * 1000' > /tmp/scr $ autopkgtest -d --setup-commands /tmp/scr tests/testpkg-simple/ -- qemu /srv/vm/autopkgtest-zesty-amd64.img [1] http://pastebin.ubuntu.com/23529002/ [2] https://anonscm.debian.org/git/autopkgtest/autopkgtest.git/tree/virt/autopkgtest-virt-qemu#n384 ** Affects: autopkgtest (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1646042 Title: Timeout running long script using adt-virt-qemu To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/autopkgtest/+bug/1646042/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
