Every VM list load reconciles each compute with libvirt. Even when nothing
had changed, that took the compute's claims and a transaction with
SELECT FOR UPDATE (and the ownership advisory lock on PostgreSQL): about
11 queries a compute, 4 of them writes. On SQLite each load queued behind
every other write of the app.
The reconcile now first compares libvirt's VM list with the database,
without a claim or a transaction, and stops when they match and no
removed record has expired. Otherwise it runs as before, reading libvirt
again under its claims, so two reconciles still cannot commit in reverse
order. With two matching hosts a list load goes from 38 queries (8
writes) to 18 (none).
test_default_storage and test_default_storage_volumes opened a pool
named default, which a compute need not have (an openEuler host had
none, and the two tests failed there). They now use the wvc-test pool
the live suite creates and removes, and run only on a named test host.
- The host graphs and the machine/bus lists connect inside their libvirt
error handling, so a down host gives empty answers instead of a 500 page
the polling script drops.
- The Secrets page lists vTPM secrets instead of failing on them, and a
secret without usage data shows an empty cell instead of "None".
- A TCP/TLS host takes a SASL password longer than 14 characters and a
login up to the Linux limit of 32.
- The compute edit page says "Edit Compute"; a host without VMs no longer
closes an extra page element; the memory graph is labelled MiB.
No page or script called it, and it answered with the disk device
types for both videos and buses. The create view keeps reading the
domain capabilities through wvmConnect.

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.
131 test modules sat next to the code they test; instances alone had
51 of them beside views.py and utils.py. They move into a
tests/ package per app, and the JavaScript checks into
webvirtcloud/tests/js. Each non-empty tests.py becomes tests/test_views.py;
the empty generated stubs are removed.
Imports of the app's own modules become absolute, paths built from
__file__ go one level up, the live helper is instances.tests.livetest,
and coverage omits */tests/*. The suite discovers the same 960 tests as
before.
