The Settings page was one tall column of cards, a label column beside
every field and True/False chosen from a select. Now an index of the
groups stays beside the cards on a wide screen and wraps above them on
a phone; each group lays its fields out in two columns with the label
above; a True/False setting is a switch; each Save names its group.
A switch posts nothing when off, so a hidden False of the same name
comes first and a checked switch's True, posted last, wins: the view
and its was-KEY check stay as they are.
- A group sent all its fields, and the ones left as they were undid
what another administrator had saved meanwhile. Each field now sends
the value the page showed, and only a field edited since is saved.
- A database error partway left the group half saved. The group is now
saved in one transaction, written as one audit row: "Settings: change
Console Scale to True, Console Clip Viewport to True".
The page listed 37 settings by name, each its own form saved as soon as
its list or field changed, with the description only in a tooltip. It
now shows them in groups (New VM defaults, Disks, Clones, Console, VM
access and owners, Snapshots and jobs, Login, Lists and pages) with each
description under its field and the label tied to it. A group's Save
button saves its changed settings, or none when one is refused, and
says which were saved; number settings are number fields with their
range. Language and theme are under Appearance with their own buttons.
A setting in no group shows under Other.
The Settings page saved whatever was posted, and some lists offered
values the panel cannot use:
- Quota Debug could not be turned off: "False" is a non-empty text and
counted as on.
- VM Clone Name Prefix showed as a True/False list, so no prefix could
be typed, and touching it set the prefix to True.
- Disk SCSI Controller listed " lsilogic" with a space, never shown as
chosen, and virtio-blk, which is no SCSI controller.
- VM Machine Type listed x86_64, an architecture; VM CD-ROM Device
listed virtio, a bus a CD-ROM cannot use.
- Logs per Page and Disk Owner UID/GID are read with int(): a letter
broke the logs page and VM create.
A migration fixes the lists and moves a value they no longer offer to
the default (the clone prefix keeps its text). A listed setting now
takes one of its choices, and every number setting a whole number in
its range, checked before it is saved.
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.
A theme change compiled Bootswatch with libsass (34 MB, upstream
deprecated) into two tracked files, which updates, rollbacks and new
Docker containers then reset. The 27 themes now ship as
static/css/themes/<theme>.min.css, built by "manage.py build_themes";
the Settings page only saves the theme name and every page links that
file (zephyr when no settings are in context, as on the 500 page).
libsass moves to dev/requirements.txt; a test checks that each shipped
file is its theme compiled from dev/scss. The "Theme SASS Path" setting
is removed, and the theme default "flaty", a typo that never applied,
becomes zephyr, the theme those installs showed. The update and
rollback steps restore an older version's rewritten theme files only
where they are modified.
