It is supported only from dom0, but it's still useful to have, to save
on simultaneous vchan connections (only waiting for MSG_DATA_EXIT_CODE).
This is especially important for Windows VMs, as qrexec-agent there have
pretty low limit on simultaneous connections (about 20).
Make qvm-run use it.
Since we use qubes.VMShell service now and send requested command on its
stdin, we need to terminate that shell after requested command -
otherwise the service will not terminate automatically waiting for
further input (next commands).
qubesd_call expect "bytes" type. Additionally serialize false value as
empty string (which is treated by python as false value), because
otherwise would be serialized to (non-empty) string, which is true value
in python.
Do not color qvm-run diagnostic messages, but also avoid ANSI control
sequences in logs. While at it, do not print 'Running ...' message when
--pass-io is used.
Most of them are moved from core-admin repository, even if tool is not
implemented yet. Some are generated using skel-manpage.py script.
This way we have complete man pages list, and sphinx will properly
warn/error about inconsistencies.
Allow use StdoutBuffer context manager inside another similar context
manager. This allows running the tests by a test runner which collect
the output using similar trick.
Lets also test basic communication primitives. `mock` python module
makes it _much_ easier, so lets use it also on python2 - requiring
backported version installed.
This differ from main core-admin API, because Admin API do not expose
separate `create_on_disk()`/`clone_disk_files()` functions. When this is
a single operation, `add_new_vm()` cannot be repurposed to clone VM.
For positional arguments default is sent to __call__ even when not
provided on command line. Exclude it in SinglePropertyAction, since
"default" value is really meant for 'properties' attribute, not
individual property.
self.default={} is mutable, so instead of modifying value derived from
that default, retrieve value, copy it and store again. Otherwise tests
(where the same parser is used multiple times) fails badly.
The same approach is used in argparse._AppendAction.
Start it using XDG Autostart feature, but exclude starting in
qubes-session - so even if package is installed in a VM, it wont be
started simultaneusly with GUI agent.
On the other hand, if some other DE session is running there (which will
be the case for GUI domain), gui-daemons will be started accordingly.
