Follow-ups from the review of the audit log layers:
- Blocking a user who is already blocked, or unblocking one who is
not, changes nothing and now writes no row, like any other edit
that changes nothing.
- write_chunk takes the request instead of the user and an optional
request; the view always had one, so the branch only tests used
is gone and every chunk 0 goes through the same audited submit.
- Tests: a busy clone creates no job and its row carries the page's
message; a later chunk that fails writes no submit row; libvirt
refusing a network or pool delete is a failed row.
The create forms of networks and storage pools checked the new name
against the host's list of networks or pools, but that list holds one
dict per object, so the name never matched and the check never fired;
libvirt refused the duplicate with its own wording. The check now
compares names: the page shows its own message, nothing is sent to
libvirt, and the Logs page gets a failed row "...: add: name already
in use".
The Logs page now records every change an admin makes to a compute's
libvirt objects, with the compute's name in the host column:
- networks: add, start, stop, delete, autostart, DHCP range, fixed
addresses, QoS and XML edits;
- storage pools: add, start, stop, delete, autostart, from web and
API; volumes: add and delete (web and API), clone and ISO upload;
- host interfaces: add, start, stop, delete;
- secrets: add, set value (never the value), delete;
- network filters: add, clone, delete, XML edits, rules and
references.
A refused or failed change is a failed row with its reason (libvirt
text through safe_text). The volume clone and upload jobs write their
row when they end; a refused submission is a failed row at once. A
volume row names the volume libvirt created (a dir pool adds .qcow2 or
.img). Volume create or delete through the API on an inactive pool
(409) is a failed row.
Network filters: the rows read "Network filter f1: add" instead of
"f1 network filter is created", and their host is the compute's name
instead of its hostname. A duplicate name or UUID no longer raises a
bare exception, and a filter XML that cannot be parsed no longer ends
in UnboundLocalError.
On a running network the change did nothing, yet the page said the
range was changed; a network without a range or an unknown address
family ended in a server error. Each is refused now with the reason:
stop the network first, or the network has no such range.

Stopping a network cut the running VMs on it off, deleting one or a
secret kept the VMs that name it from starting, and stopping a pool
took the disks of running VMs away, all without a word. Each is now
refused with the VMs (and, for a secret, the pools) that need it:
stopping while a running VM uses it, deleting while a VM's definition
names it. A disk given by its file path does not need its pool's
definition. The API's pool stop is refused the same way.

Twenty-five prompts asked only "Are you sure?", and on the storage page
one handler asked the same before every button, Start and Enable
included. Each destructive button now names its object and says what
happens: a stopped network cuts running VMs off, a deleted pool keeps
its files, a deleted volume loses its data, a reverted snapshot loses
the changes made since. Saves no longer ask, and disabled buttons lose
prompts they could not show. The VM QoS messages said to restart the
network where the VM has to be powered off and on.

Column offsets without a breakpoint applied below it, where the column
is already full width, so the change password, compute, user, VM
create and VM settings forms ran past the right edge on a phone. Each
offset now starts at its column's breakpoint. The interface and network
detail lists were rows directly inside rows and sit in a column now;
the compute form loses a Bootstrap 3 thumbnail padding that broke its
gutters, and the add-rule dialog's hint is no longer cut off. The page
test checks both grid rules on every page.

Twenty tables had no .table-responsive wrapper, so on a phone the user
list, compute list, VM lists, network and network filter pages scrolled
sideways as a whole. Each table now scrolls inside its box, as the
other ten already did. The page test walks the network page too, and
checks that every table on every page has the wrapper.

The pool, network and interface cards had a solid green or red header
with light text, and status words (Connected, ON, OFF, the DRBD state)
were in the theme's green or red text colour. axe found them below the
WCAG AA 4.5:1 contrast on the live theme (4.29:1, 3.52:1), on the
default zephyr theme, whose green is light (2.5:1), and on dark themes
(darkly 1.18:1).
The card headers, and the status words as badges, are now the theme's
pale status background with its dark status text (bg-*-subtle with
text-*-emphasis). Bootstrap derives the pair from each theme's palette,
and it does not depend on the page's background: the dark Bootswatch
themes keep light-mode emphasis colours, which on their own would be
dark text on a dark page. The card border keeps the status colour.
A network's QoS form whose rate was not a whole number (abc, 1.5) made
wvmNetwork.set_qos raise a ValueError that the view did not catch: the
request ended in a server error. The page's pattern stops this in a
browser, but the server must refuse it too. set_qos now says "QoS rates
must be whole numbers", and the view reports that, as it does a libvirt
error, and goes back to the network's page.
The create-network form only checked the characters of its subnets, so
192.0.2.0/33 or 999.0.2.0/24 passed and network_size raised a
ValueError: the user got a server error instead of a message. So did a
subnet too small for the gateway, DHCP range and broadcast address that
network_size derives (0.0.0.0/32, 255.255.255.255/32), and 192.0.2.0/31
or a bare address gave an inverted DHCP range.
Each subnet field now parses its value as a network of its IP version
and refuses it with a field error otherwise. An IPv4 prefix must be /30
or shorter; the IPv6 prefix must be /64, which the view checked after
the form and now the form does.
An accessibility scan of the pages on a real host (the earlier scans ran
on libvirt's test driver) found unnamed elements the test driver never
renders: the network page's add fixed address buttons and their dialog
fields, the XML box of each nwfilter's details dialog and the convert
checkbox of the volume clone dialog. The buttons get a title, the labels
a for= and the fields an id, the XML box an aria-label.
The MAC field's pattern ([0-9/:]+) had no hex letters, so the browser
refused nearly every MAC address (52:54:00🆎cd:ef) and no IPv4 fixed
address could be added from the page. The host name field of both
dialogs ([a-zA-Z0-9_]+) refused names such as web-01 or db.lan. The MAC
takes hex digits and ":", the name letters, digits, "_", "." and "-";
the server already escapes both into the network XML.
An accessibility scan with every modal opened found 49 fields without a
name: the labels of the instance create forms (custom, template and each
flavor's modal), the interface, network, secret and storage pool modals
did not point at their fields. Each label now has a for= and its field an
id, prefixed per form (and per flavor), so a click on the label focuses
the field too. The "Advanced" collapse buttons and the memory and
processing bars are named.
The VCPU config select had id="vcpu_mode" in each of these forms, nine
times on the create page; the unique-ID test did not see it as the test
driver reports no CPU modes. The id goes (nothing used it), and the test
now renders that branch.
An accessibility scan (axe-core, WCAG 2 A/AA) of every page found 87
elements without a name. Icon-only buttons and links (the navbar's
administration menu on every page, the add/create buttons, the flavor
delete and back buttons) get a title, which is also their tooltip; the
labels of the language, architecture, chipset and filter selects point
at them; the memory bar is named. The shared delete confirmation page
had an empty <title> and heading, as no view passes "title": it says
"Delete <object>". The power-off form's aria-label was misspelled.
Rendered through every URL on libvirt's test driver, the pages had
duplicate IDs and markup browsers repaired silently:
- Each flavor modal's "Advanced" button toggled #flav-add-collapse, the
first modal's section; every modal now has its own. The flavor and
template copies of the custom tab's control IDs, and the template
tab's unused images input, are gone.
- The VM page's action icons and the XML editors were styled by
repeated IDs; they use classes.
- Modal forms opened inside modal-body and closed after modal-footer;
they wrap both. Stray end tags and duplicate attributes are removed,
paragraphs no longer hold modals or rows, table heads have a row, and
the create page closes its row and column.
- html lang is the active language instead of "en".
A test walks every URL as a superuser and fails on a repeated ID. The
console page still has no doctype: its full-height layout relies on
quirks mode and needs its own check.
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.
Four lookups built XPath expressions from values that come from
requests (CodeQL py/xpath-injection, plus get_capabilities, which
CodeQL did not flag; the pages are for superusers):
- The architecture in the create wizard's URLs went into
arch[@name='...'] in get_emulator, get_machine_types and
get_capabilities: "nope' or '1'='1" matched every architecture. It is
now an XPath variable ($arch), which is never parsed as XPath.
- Network filter rules were found with a predicate built from the
posted action, direction and priority: a quote raised SyntaxError (an
error page). The rule is now found by comparing its attributes.
- unset_qos put the posted direction into the path, so "*" removed
every bandwidth setting. It accepts inbound and outbound, as set_qos
does; the network page shows an error for anything else.
No other XPath in vrtManager is built from a value; the remaining
expressions are constants. The tests fail on the previous code.
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.
- Routers use path converters (use_regex_path=False): computes, instances
and flavors take <int:...> ids, so non-numeric ids get 404 and
drf-spectacular derives the parameter types itself.
- Each method declares what it really returns: detail serializers,
a shared StatusSerializer for status-only replies, no request body for
actions. Instance properties used by the details serializer get return
type hints.
- The create-instance API drops the firmware field. Its only accepted
value was "" (BIOS), which produced an empty, invalid enum, and the
UEFI branch behind it was unreachable. Clients that still send it are
unaffected; DRF ignores unknown fields.
The schema now passes spectacular --validate --fail-on-warn; a test
keeps it that way.
- Computes API: mark password as write_only in ComputeSerializer, restrict ComputeViewSet and architectures to IsAdminUser.
- Instances API: enforce user ownership tenant isolation in InstanceViewSet.list, restrict MigrateViewSet and CreateInstanceViewSet to IsAdminUser, require IsAdminUser for mutating FlavorViewSet.
- Storage, Network, and Interface APIs: restrict StorageViewSet, VolumeViewSet, NetworkViewSet, InterfaceViewSet to IsAdminUser.
- AppSettings & NWFilters: protect appsettings and nwfilter views with @superuser_only (403 Forbidden for non-superusers).
- noVNC Console: sign tokens with TimestampSigner (salt='console.novnc', max_age=600), verify signature and user authorization in novncd with backward-compatible fallback for debug/test mode.
- Accounts: avoid hardcoded default admin password; generate cryptographically secure random password unless ADMIN_PASSWORD is set (preserve 'admin' in test runner).
- gstfsd daemon: bind to 127.0.0.1 by default instead of 0.0.0.0.
- Tests: added comprehensive test coverage for API security, token expiration/rejection, and view permissions (132 tests passing).
