Fix missing semi-colon and new line
Handle KDE with specific arg/desktop file
core-admin-client side had less strict rules for hostname than core-admin,
leading to unexpected empty qubesd response. Fixed by copying the logic from core-admin.
Qubes().domains.refresh_cache() tries to preserve cached VM objects if
the class matches - this way if an application keeps reference to any,
it will still be the same as freshly obtained from the collection, and
also it will receive cache updates/invalidates based on events.
The check for class change was invalid - on core-admin-client side we
have just one QubesVM class with 'klass' attribute. This leads to VM
objects being disconnected from VMCollection and stale properties cache
there (because they no longer receive events).
Fix the check.
And also add a test if indeed the same object is returned.
Allow configuring options per VM or globally per GuiVM. The
qvm-start-daemon program reads the options from VM features, and
generates a configuration file for qubes-guid.
Requires QubesOS/qubes-gui-daemon#47 (customizing the configuration
file).
Do not require permission to list sys-gui itself just to get keyboard
layout. Listing itself is not sensitive (sys-gui knows it exists), but
it will make other tools request its properties, which may not be
desirable.
Application that runs EventsDispatcher can safely use also cache , which
greatly improve performance. This is because cache then is properly
updated/invalidated when needed.
Instead of modifying each application to explicitly enable cache based
on this simple rule, make it implicit when EventsDispatcher is created.
Do not enable caching when EventsDispatcher is created only temporarily
in wait_for_domain_shutdown.
QubesOS/qubes-issues#3293
Both tools issue a large number of Admin API calls and greatly benefit
from a cache filled with a single per-vm Admin API call
(admin.vm.property.GetAll). In case of qvm-ls, this also saves multiple
admin.vm.CurrentState calls (power state is given in the admin.vm.List
response too).
QubesOS/qubes-issues#3293
Power state changes are signaled with events too, so it is possible to
cache it and update/invalidate cache with events.
Additionally, admin.vm.List returns a power state, so the cache can be
populated early. This in particular greatly improves qvm-ls performance -
eliminate admin.vm.CurrentState call at all.
QubesOS/qubes-issues#3293
Qrexec itself does not support loopback calls. Since a call into dom0
is a common case for GUIVM (which may be dom0) to do, add a convenient
handling inside vm.run_service() function.
FixesQubesOS/qubes-issues#5140
When caching is enabled, reduce number of calls by getting all the
properties at once. If the call is not available (for example because of
the policy), fallback to getting individual values.
QubesOS/qubes-issues#5415
Reduce Admin API calls by caching returned values. The cache is not
enabled by default, because it could result in stale values being
returned. It can be enabled by setting 'cache_enabled' to True on
Qubes() object. This is safe in two cases:
- the application don't care about changed values - like a short-lived
process that retrieve values once (for example qvm-ls)
- the application listen for events and invalidate cache when property
is changed
For the second case, invalidating the cache on appropriate event
(property-set:*, property-reset:*) is done before calling other event
handlers. This is because the event may try to access the property value
(not necessary from the event arguments), so we need to be sure it will
see the new value.
FixesQubesOS/qubes-issues#5415
When qubesd returns an name of VM or other object, as part of another
call (reading a property, listing devices etc), it's safe to assume that
object exists. Do not try to list it, which could be prevented by qrexec
policy. This means a VM object would be returned (for example in
vm.netvm property), which potentially could not be listed through
app.domains collection. This may lead to some corner cases, but
generally should ease handling of restricted policy.
This does not affect practical information the management VM have access
too, as those names are already returned. It's just client side python
wrapper that didn't allowed to access them.

The code assumes that QubesVMInUseError is thrown for a failed
dependency check, but there are also other reasons. We need to
handle the case when dependency list is empty, and also display
the original message.
See also QubesOS/qubes-core-admin#308 for which this was needed.

Add missing docstrings
Add a test for vm.get_mem()
Update tests to mock admin.vm.CurrentState
qvm-ls: display memory as integer number
Use admin.vm.CurrentState method for power state and memory
FixesQubesOS/qubes-issues#5166
qvm-shutdown with the --wait option checks if the machine
state is 'Halted', but a disposable VM is usually deleted by
the time of the final check, resulting in a non-zero exit code.
This change handles properly disposable VMs, and makes sure
we always output an error message when finishing with a non-zero
exit code.
FixesQubesOS/qubes-issues#5245.
Depends on the method introduced in QubesOS/qubes-core-admin#307.
Adding the get_mem() method using the same CurrentState admin
method also fixes the bug with qvm-ls not showing memory, see
QubesOS/qubes-issues#5166.
Due to strangeness of KeyError (it overrrides str method) in some
cases exceptions received superflous quotation marks when inheriting
from it.

* origin/pr/111:
Add tests for --tree option of qvm-ls
Sort domains in network tree list
network tree manpage entry added
added feature to list domains as network tree
This change introduces a complete rewrite of the argument parser for the `qvm-pool` tool.
As suggested by @marmarek in qubes-issues#5407, the goal is to be consistent with other tools such as `qvm-device`, `qvm-volume` etc.
(resolvesQubesOS/qubes-issues#5407)
If the VM is powered off shortly after startup, it may happen that
qubes.SetMonitorLayout would start it again. Avoid this by using
autostart=False argument to run_service() function.
Note that there is a vm.is_running() check at the beginning of the
function already, but if it happens while the VM is cleaned up, it may
still report that it's running, but at the time of run_service() call it
is not.
This allows to run a service but do not cause a qube to be started it
isn't already running. This is especially useful for background /
internal calls designed to service a running target VM - if VM is not
running, those do not make sense to be called in the first place.
Specifically, this will allow qvm-start-gui to avoid re-starting a
domain while calling qubes.NotifyMonitorLayout, when a VM is shutdown
shortly after its startup.
Previous commit introduced protection against uncommon (potentially
malicious) compression filters. This breaks restoring backups made with
a custom compression filter. Add an option to override this check, by
naming compression filter to use explicitly.
Compression filter named in a backup header is executed in restore
environment (commonly dom0). While this field is properly authenticated,
there may be cases where backup archive comes from less
trusted source, like migrating from potentially compromised
system.
Modify backup header parsing code to add field specific validators.
Whitelist only know crypto, hmac and compression algorithms.
