Title:
Does not reply on dbus when busy (e.g. downloading)
Status in Ubuntu system image (server/client/updater):
Triaged
Bug description:
We ran into the issue that system-image-dbus would sometimes not reply
on snappy. After long debugging and deep dive into the go-dbus code it
seems that system-image-dbus simply does not reply when its busy, at
least in the snappy branch.
This may well be fixed in the 3.0 branch so here is a test and it
would be great to know if that works with the curl backend and the 3.0
branch:
Ensure there is something for s-i-dbus to do (e.g. download new image):
$ rm -f /writable/cache/*.tar.xz
$ dbus-send --system --dest=com.canonical.SystemImage
--type=method_call --print-reply /Service
com.canonical.SystemImage.CheckForUpdate && sleep 1 && dbus-send
--system --dest=com.canonical.SystemImage --type=method_call --print-
reply /Service com.canonical.SystemImage.DownloadUpdate && sleep 1 &&
dbus-send --system --dest=com.canonical.SystemImage --type=method_call
--reply-timeout=5000 --print-reply /Service
com.canonical.SystemImage.Information
Running the above gives me:
"""
method return sender=:1.54 -> dest=:1.53 reply_serial=2
method return sender=:1.54 -> dest=:1.55 reply_serial=2
Error org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible
causes include: the remote application did not send a reply, the message bus
security policy blocked the reply, the reply timeout expired, or the network
connection was broken.
"""
So it appears the curl backend is not quite there for snappy yet.
