The bus list of a disk on the VM create page came from the host's disk
device types: choosing "disk" for an added image offered cdrom, disk and
lun as its buses. The disk branch of get_disk_buses now returns the
host's disk bus types, the list the page starts each disk with.
Each poll of a host's overview graph held a worker for one second between
two CPU samples. The answer now carries its sample, signed with the time
and the compute; the next poll sends it back and the usage is taken since
then, so a point is the average since the previous one (normally 5 s, at
most 15 s). Without a sample, or with one that is altered, older or from
another host, or when the host restarted, it is measured over one second
as before.
A sample is one reading; the busy share was mixed from separate readings,
counted guest time twice (it is part of user) and added half a percent.
A host that cannot be read leaves a gap in both graphs instead of a zero
CPU point and a broken memory axis.
The overview page decided whether the host is up with a TCP probe of
the compute's hostname. For an ssh compute named by an ssh_config alias
or reached through ProxyJump, that name and port cannot be reached from
WebVirtCloud directly, so the probe failed while the connection worked:
the page showed the host details and never started the CPU and memory
graphs. The overview now uses Compute.status, the connection
WebVirtCloud uses for everything else.
The compute list shows why a host is not connected (Compute.connection_error)
under "Not Connected", for example a host key verification failure.
Checked against the ssh compute of the test setup through an
ssh_config alias: the previous code renders the overview with the
graphs off, the new one with them on. Both new tests fail on the
previous code.
computes.views.get_compute_video_models had no URL and no caller, and
ComputeManager.get_video_models was used only by it. The video models
of the create page and the VM settings come from wvmConnect directly.
Super-linter ran from the unpinned :latest image and, because of
branches-ignore: [master], never on pull requests to master. Ruff now
checks syntax errors and pyflakes rules (E9, F) on every push and PR.
Fixes the existing findings: unused imports and variables, an unused
duplicate import in instances/tests.py, and the star import in
accounts/views.py. settings-dev.py keeps its star import of the base
settings.
compute_graph (text/javascript) and the machine type, disk bus, video
model and domain capability views (text/html) return JSON; send it as
application/json. create_instance_w1.html builds the chipset <option>
elements with .val().text() instead of string concatenation.
