The workbook kept every cell as an object: a 100 000-row Logs download
took some 400 MB in a web worker. openpyxl's write-only mode writes the
rows as they come (85 MB for the same file, measured), and the Logs rows
are read as tuples, not model objects. The bold, frozen, filtered header,
the column widths and the text cells stay as they were.
The page where a user changes their own password and the one where an
administrator sets a user's password shared an old card: a horizontal
form, a blue Cancel and a green Change. The administrator's had Django's
"Password-based authentication: Enabled/Disabled" with a paragraph about
other backends, and its password fields stayed while Disabled was chosen.
Both pages now have the user and group forms' layout, each its own
template. The administrator chooses how the user signs in, With a
password or Without a password (such as LDAP), and the password fields
and "must change it" show only with a password; Cancel goes back to the
user. A user's own page says that their other sessions end, or, when
they must change it, that they choose one before going on, without a
Cancel. A refused password is said at its field only, without the
general "Wrong Data Provided". The section styles of these forms move
into webvirtcloud.css.
The group form put every user as a checkbox in one unsorted list, the
members among them, with no way to find one: past a few dozen users a
wall of names. Its name field ran the width of the page.
It now has the user form's sections (Group, Permissions, Members), each
with what it is for beside its fields. Members come first, then everyone
else, each by username with their full name; a search box filters them
by username, name or e-mail (table_filter.js). A form's search, marked
data-forget, starts empty: the list pages remember theirs per page title,
which here is the same for every group. Hidden users stay in the form,
so saving while filtered keeps them. The button says Create group or
Save changes.
The create and edit pages of a user had one form for both, ordered for
editing: permissions first, the name and password folded below them and
the quota folded and closed at the end; a new user's name came last.
Both pages now go Account (name, password, may sign in), Role, Quota,
then Groups and permissions, each section with what it is for beside its
fields. Template editor and Superuser become one Role choice with User:
choosing Superuser hides the quota and permissions, which a superuser
does not need (no quota check applies, every permission is theirs); it
keeps the is_staff it had. The quota is always open: each limit takes a
number from 0, or No limit, which is kept as -1 as before; memory is
entered in GiB and kept in MiB, shown exactly so saving a user again
changes nothing. The button says Create user or Save changes.
Each row of the Users page asked has_perm whether its user may clone:
two queries a user (the user's permissions and the groups'). The list's
query now annotates it with one Exists over the clone permission, given
to the user or to a group of the user; a blocked user is shown without
it, as has_perm did. The page's query count no longer grows with the
users.
The Users, Groups and Removed VMs pages were bare tables: rows of
coloured icon buttons without words, five columns of small checks for
a user's role and permissions, dates broken over three lines and a
lone "+" for a new entry. The owner chose a directory layout from three
rendered options; it follows the host pages' cards:
- Each list is a card with its count and search in the header and one
list-group item per entry, which stacks on a phone without scrolling.
- A user shows their role as a badge (Superuser, Template editor) or
"User", Blocked as a red badge, their groups, a granted clone
permission and live API tokens, and the last login on one line;
role and status are searchable. Edit is the visible action, the menu
holds View profile, Block or Unblock and Delete; Block and Delete
are disabled on one's own account, which the server refuses anyway.
- A group shows its member and permission counts; its name opens it.
The page's title said "Users".
- A removed VM shows its UUID, the host it left, its owners and when
the record was made and expires.
- Logs keep their table in a card, the server search in its header,
the count of matching rows, Done and Failed as badges, and a message
column wide enough to read on a phone.
The user form was one long column of horizontal fields. The owner
rejected three boxed layouts and chose one led by what the user may
do: the Active switch, Template editor and Superuser as two cards,
groups as chips, the user's own permissions as switches each saying
what it allows, then the name and password and the quota folded into
details whose summaries tell their values (-1 as "any"); they open on
a new user and on an error inside them. A refused group or permission
is said beside its field. The group form follows it: the name, what
its members may do, its members as chips. Cancel goes back to the
list instead of the browser history.
A tombstone kept the VM's name and UUID but not its compute, so the page
could not say where the VM had been. It now stores the compute's name (as
text: the compute may be the one deleted) and the list shows it; records
made before this have no host. Deleting a record says so, and the admin
tables use scope="col" instead of the invalid span="col".
Closes#217
NEW_USER_DEFAULT_INSTANCES names VMs, and a name may repeat across hosts.
A name with no VM, or with one on two hosts, made creating any user a 500.
The create form now looks the names up and says which one is not exactly
one VM; the user and its default VMs are saved together.
- A failed login writes the name it was tried with, as typed: a control
character in it made every download holding that row fail, as the
workbook cannot hold one. Workbooks now write it as \x01; the VM
report shares the code.
- A download held every matching row in memory: it now takes the newest
100000, and its About sheet says when the search should be narrowed.
- The administrator's password form took "password-based
authentication: Disabled" with "must change it at the next login":
the change form asks for the old password, which the user then never
had, so they could not get past it. That combination is refused, and
an administrator cannot disable their own password.
- A user who must change the password could still use the API with
their tokens. A token is now refused until they change it, as the
pages are.
The search box filtered only the 100 rows on screen, in the browser: an
older row seemed not to exist. The page now searches on the server, in
every row's user, host, VM, VM UUID, message and IP, as plain text, and
can show the failed rows only; its pages keep the search.
Failed rows are marked red, dates carry the year and the time zone, and
a VM's rows link to the VM while it is in the panel. Excel downloads the
rows the search chooses, all pages of them, with the VM report's
workbook (text stays text).
The administrator's password form has "The user must change it at their
next login". With it, the user is sent to the change form until they
choose their own, as the generated admin password already does.
- An administrator could block, delete or demote (unset Active or
Superuser on) their own account, and with it the last one, leaving the
panel without anyone to undo it. These are now refused.
- The user form showed "No password set." for users who have one: its
password field never read the user's password. Its "Set password"
link went to ../password/, a page this panel does not have. The form
now says whether a password is set and links the page that sets it.
- "Staff status" said "can log into this admin site"; here it lets a
user change and delete the template VMs given to them, and is now
called Template editor.
- A quota of 0 counted as no limit, like -1, so a user's quota could not
be taken away. Now -1 has no limit and 0 allows none; the help says
so, and the labels give the units: memory in MiB, disk in GiB.
- A user's page for a user that does not exist answered with a server
error instead of not found.
- The user list said "None" for a user who never logged in; it says
"never", and dates fit their column.
- The password form's labels no longer break mid-word.
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 Logs page now records the panel's own records too: users (add,
change with the changed fields, delete, block, unblock, an admin's
password set, a user's own password change including the first-login
one, own profile edits), groups with their members and permissions,
VM owners from the accounts pages and from the VM page, OTP QR code
mails, flavors from web and API, app settings and the theme,
removed-VM records and SSH keys. No row carries a password or a key.
- A user is created in one transaction: when a VM named in
NEW_USER_DEFAULT_INSTANCES is missing, no half-made user stays.
- The OTP mail checks the email address before it creates a device;
without one it writes a failed row and makes no device.
- The VM page's owner rows read "VM web-1 owner bob: add" and
"...: remove" instead of "Add owner: bob" and "Delete owner: 17"; a
second owner refused by the single-owner setting is a failed row.
Owner rows keep the VM's host and name, so the VM's log tab shows
them.
- A setting or theme posted with its current value is no change and
writes no row; the old free-text setting rows are gone.
Host-side objects (networks, storage, interfaces, secrets, filters)
follow in the next layer.
The Logs page shows who added, changed or deleted a compute, from web
or API, and every login, failed login, lockout and logout, with the
client address and a Result column (Done, Failed, Unknown for older
rows). A failed change is recorded with its reason and the error still
reaches the user; a refused one is recorded too.
- logs.audit.write saves each row in its own savepoint and never
raises, so a log write cannot break or undo the action it records.
The audit() context manager writes one row when the change ends.
- Logs gains success and ip; user, host and instance are wider and
date is indexed. The page orders by date then id.
- A compute edit names the changed fields; an edit that changes
nothing writes no row, and an empty password field is no change.
- A compute's VMs leaving the panel get a system row each: owners
kept on the Removed VMs page, moved to another compute, restored,
left without owners, or the removed record expired.
- Job rows carry the result. A job's log entry that cannot be
computed is logged and skipped instead of rolling back the finish
(test_service.py changes this on purpose).
- Logins are recorded by signal receivers; CustomLoginView is removed
and the plain LoginView is used. A wrong OTP code is a failed login,
counted by django-axes toward the lockout.
Panel records and host-side objects follow in the next layers.
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.
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.
