create_task has the following note:
Important: Save a reference to the result of this function, to avoid a
task disappearing mid-execution.
Convert existing usage of create_task to run_bg_task, if that
create_task is not actually storing the result.
The network view code used to crawl all over the network model object,
which isn't really going to work with the upcoming client/server split.
So this adds a much better defined interface between the view and
controller.
* annotate a few missed string literals with _()
* try to consistently use named placeholders when formatting strings
for display (i.e. _("frob the {thing}") not _("frob the {}")
* run selector values, form captions and form help through _() before
display
* use ngettext in one place. not sure if there need to be more...
* reduce cuteness about how strings are constructed in a few places
Mark all devices with DHCP enabled as pending when the config is
applied, and mark them as timed out ten seconds later if they have not
received any addresses.
The visible impact of this is that the addresses for a NIC are now
displayed underneath its name and a long "info line" (i.e. mac / model /
vendor) for a nic no longer distorts its table.
This lays the groundwork for better handling of NICs that fail to dhcp
and things like that.
The main thrust of this is to not create virtual interfaces until
applying the config.
This meant that the network model has to change a bit to be able to
represent interfaces that do not yet exist on the system. I did this
by ripping out most of the existing network device code: now a
NetworkDev is really just a wrapper for the config for a device and (if
it exists) the netlink data too. A few places had to adjust to checking
if the netlink info is available before accessing it but all in all it
was not that painful.
There are a few other refactorings in this commit that perhaps should be
split out (how the bond parameters are handled, some stuff about
resizing the table rows when interfaces are edited) but it doesn't
really seem worth it.
