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.

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.
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.
