- noVNC's own web client (app/ except the bell sounds, vnc.html,
vnc_lite.html, defaults.json, mandatory.json): the console imports
only noVNC's core, and novncd serves no web pages. AUTHORS, LICENSE.txt
and package.json (the version) stay.
- 24 cached icons no {% bs_icon %} asks for; the icon cache test now
also fails on an icon nothing uses.
- Ace's ext-textarea.js, which nothing loads.
- instances/fixtures/initial_data.json, for an app ("create") that no
longer exists; migration 0006 seeds the flavors.
- webvirtcloud/asgi.py: gunicorn runs the WSGI application only.
- instances/templatetags/tags_active.py: a copy of common_tags'
class_active that no template loads.
- .github/linters/.hadolint.yaml, from super-linter, which no workflow
runs anymore.
Each was checked with git grep across every tracked file (templates, JS,
shell, unit files and the extensionless console daemons) and for
dynamic use (URL names, template names, registries):
- vrtManager: host_is_up, is_kvm_supported, get_emulators,
get_file_extensions, both get_network_forward, get_snapshots,
get_storages_images, get_os_type, get_host_arch, the get_pretty_* trio
and, in util, is_kvm_available, randomMAC, get_max_vcpus, compareMAC,
pretty_mem, pretty_bytes and validate_uuid; with them the port
constants only host_is_up read. Some were reached only by their tests,
which go too.
- The flavor edit page: nothing linked to it; flavors are created and
deleted on the Flavors page and edited through the API.
- computes.validate_name, UserForm.identity_has_errors, the has_perm
template tag, the ALLOW_EMPTY_PASSWORD setting nothing reads,
hidePleaseWaitDialog, default_app_config (ignored since Django 4.1)
and the Python < 3.6 lines of secret_generator.py.
js-cookie served only table_filter.js, which kept a list's search in a
cookie for a day; the cookie went to the server with every request.
The search is now kept in the tab's sessionStorage: it stays across
reloads and pages in that tab, a new tab starts empty, and the server
never sees it. The library goes.
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.
The VM's XML editor takes most of the window's height and is framed like
a form field. The review dialog shows removed and added lines on a red and
green tint, and each part of the diff starts with its line number instead
of the unified diff's @@ header.
A checkbox marked a device as booting and also chose what Up and Down
moved, which moved every checked device at once: to move one device the
others had to be unchecked and checked again. The buttons sat apart
from the rows, and a VM booting by device type got a note that did not
say what to do.
Now the devices the VM tries are a numbered chain, each with its own
up, down and Remove, and the others are listed below it with Add; the
posted order is unchanged. Devices read by kind first (CD-ROM sda,
Disk vda) with their file or network below; a VM booting by device
type says so and how to choose an order. Autostart and the boot menu
sit below, lighter. Focus stays on the device that moved, and on a
narrow screen a device's buttons wrap below its name.
The Turkish catalog says "Ön yükleme" and "sanal makine" throughout,
also in the Power tab texts.
The host pages lose their last inline scripts: the overview's charts
(host_graphs.js), the New pool, New network and New interface dialogs
(pool_dialog.js, network_dialog.js, interface_dialog.js), a network's
and a network filter's XML editors and dialogs (network_page.js,
nwfilter_page.js, nwfilters_page.js), the secrets page's labels
(secrets_page.js, its texts from the view as usage_texts) and a pool's
page with the ISO upload (storage_page.js). Their URLs and messages are
data attributes of the elements they belong to; the upload reads its
token and address from its form. No template has an inline script or
an inline event handler any more.
The VM lists lose their inline scripts and handlers: host_groups.js
collapses a host's VMs in the grouped list, new_vm_dialog.js reads the
new-VM dialog's CPU bars and capacity lines, and console_window.js
(loaded by every page) opens a console button's window, on the lists and
on the VM page alike. A list row's Start no longer calls the please-wait
dialog, which the list pages do not have (the call only raised an
error). The VM page's URL placeholders take the __name__ form the other
pages use.
The create wizard's two pages lose their inline scripts and handlers:
create_machine.js (machine types of the chosen architecture, Next, the
XML editor) and create_instance.js (volume and network pickers, disk
source, presets and flavors, row lists, a refused form restored). Their
URLs and messages are data attributes of #select_chipset, #next and
#create-vm-form; URL parts use __name__ placeholders, so the volume list
URL is now the routed one with its trailing slash. The XML form shows
the please-wait dialog through data-please-wait. The page script tests
read the static files.
The VM page's thirteen inline script blocks and its inline handlers move
to static files: instance_page.js (tabs, OS details, clone names and
MACs, Add disk dialog, boot order, host devices, migrate plan, console
window, switches that send their form), instance_stats.js (charts and
the Logs view) and instance_status.js (the reload when the VM's state
changes). Their values and messages come as data attributes of the
elements they belong to, page-wide ones on #vm-summary; a form marked
data-please-wait shows the please-wait dialog. Three blocks that did
nothing are dropped: popovers (the page has none), the video model
preselection (the server selects it) and the delete form's poll stop
(that form is on the destroy page). The HTML sink inventory now also
reads the app's own scripts.
A step towards a Content-Security-Policy without inline scripts. The
scripts every page or many pages share now load from static files: the
error focus of base.html, the please-wait dialog, the sign-in forms'
password toggle and busy button, the jobs pages' reload while a job
runs, and the start of the job panel and of the VM list's state poll,
whose values come as json_script data. Cancel links go back through a
data-history-back attribute instead of a javascript: URL. The IE8
html5shiv/respond.js block, X-UA-Compatible and shrink-to-fit are gone:
no supported browser reads them.
A VM list showed what it read when it was loaded: a VM stopped from
inside its guest or with virsh, or made or removed elsewhere, showed only
after a reload, unlike the VM page, which reloads when its VM's state
changes. The lists of all VMs and of one host's VMs now poll the states
of their VMs, at once and then every 5 s as the VM page does, and reload
when an answer differs from the one before. The states come from one
libvirt call per host; a user who does not see hosts gets only their own
VMs. The page in use (a dialog, a field, an unsaved XML edit, a job
outcome shown) holds the reload until it is free; that check is shared
with the job panel.
Deleting or detaching a disk, deleting a network card, forcing a VM off,
reverting or deleting a snapshot, stopping or deleting a pool, a
network, an interface, a filter or a secret, and the other actions that
ask first opened the browser's yes/no box (confirm()), and the ISO
upload told its mistakes in the browser's alert().
One dialog in the base page now asks for all of them: its title and
confirming button carry the button's own words, its body the button's
question, the confirming button red for a destructive action. Confirmed,
the button is clicked again, so its form sends what it did before. A
button inside another dialog (the flavors) hides that one while asking
and shows it again after; Cancel gives the focus back, and the
confirming button acts once. The ISO upload's mistakes show in its
dialog's error box, announced.
Settings > Users was a bold title, an unlabelled "+" and a table of
names with a trash icon. The owner chose this layout from three
rendered options: one list of owners, each with what it may do
(change settings, delete the VM, change console settings, or power and
console only), Edit rights and Remove, an empty state, and a labelled
"Add owner".
- Remove and Edit rights come back to the VM's Users tab: the return
address carried #users unencoded, so it was lost, and Edit rights
went to the user's account page. Both accounts views now go to a
?next page of this site.
- The add-owner list offers only users who are not owners yet and not
administrators, who can use every VM anyway; a superuser owner also
took the only place when a VM may have one owner.
- The unused del_owner view and URL are removed: the list uses the
accounts page, which asks before removing an owner.
XML:
- An XML edit not saved yet is kept: the page no longer reloads itself
when the VM's state changes, and the browser asks before leaving it.
A state change lost the edit.
- The button that opens the review dialog reads "Review changes"; it
did not save, as "Change" suggested. Closing the dialog gives focus
back to the editor.
The top of a VM's page was one line of values between pipes, an icon for
the guest agent and a hidden snapshot count, then a row of big action
icons; the host links sat in a bar fixed to the bottom of the window,
over the content.
One card now holds it all (design chosen by the owner from four):
- the name with the state badge, the title under it, and where the VM
is: its host and the host's VM list for administrators, the VM list
for owners;
- OS details (with a connected guest agent) and Refresh;
- the guest agent's state in words and the snapshot count;
- CPU, memory, each disk with its device name and size, and the IPv4
addresses, labelled;
- the page's sections as small labelled pills in the card's footer: one
row from 992 px, wrapping below.
The page has no other heading: base.html's heading area is a block it
leaves out.
Each section below it (Power, Access, Resize, Snapshot, Settings, Stats,
Destroy) is a card of the same kind, so the page reads as one design
(owner's choice of two): its sub-tabs as a small underlined nav in the
card's header, its panes in the card's body without their own borders.
Buttons are of normal size in the theme's primary colour, and those that
cannot be undone (Power Cycle, Force Off, Destroy) in the danger colour.
The Stats charts lose their coloured borders. instance_tabs.js finds the
Settings tabs by their tablist role.
The bottom bar and its setting (VIEW_INSTANCE_DETAIL_BOTTOM_BAR) are
removed, and with it the CSS that kept the old Settings tabs on one line.
As the storage and network pages; plan reviewed with Codex.
- The list is grouped by type (bridges, bonds, VLANs, ethernet; a type
the host has none of is left out), three cards a row, with a search
of their names, MACs and networks (table_filter.js, which now takes
any element with data-search as a row); a card per interface: its link
as the kernel reports it (up green, down grey, another state or
unknown told as such, no red card for a link that is merely down),
MAC, MTU, speed when known, the members it reports and the libvirt
networks that use it, linked.
- An interface's page: an Interface card (type, libvirt's own state
where it manages interfaces, link, start mode, MAC, MTU, speed, STP,
networks using it); on a host whose libvirt changes interfaces, a
card per family with how it is addressed and its addresses; the
members of a bridge, bond or VLAN with their link and speed, or that
none is reported; for a bridge, the running VMs' cards on it,
directly or through a network using it, with their tap and MAC,
linked (wvmInterface.get_vms: one domain listing). Not the bridge's
delay: netcf tells it in seconds, the udev backend in hundredths.
Start or Stop in its heading, Delete in its menu, disabled while it
runs, on hosts that can change interfaces only.
- A host whose libvirt only reads interfaces says so once, with that
it does not tell their addresses, instead of "None" on every page.
- The New interface dialog is one form, as the New pool and New
network ones (choice_dialog.js, radio_card.html): Bridge or
Ethernet, a bridge's member from the devices it can take, an
ethernet interface's device from the ones the host does not define
yet, a static address's fields with its choice; a refused interface,
or one libvirt refuses, opens it again with what was entered; a made
one opens its page.
- networks_by_device maps the libvirt networks to their bridges or
interfaces on the page's own connection.
As the storage pages; reviewed with Codex.
- The list is a card per network: its name with Active or Stopped and
Autostart badges, its type (network_mode: Isolated, NAT, Routed,
Open, Bridge, Macvtap, SR-IOV), its device, and each address with
its DHCP range; a bridge or macvtap network's addresses come from
the outside network.
- A network's page: its heading starts or stops it, the menu sets
autostart and deletes a stopped one. A Network card tells its state,
type, bridge or interface, MAC and what the type does; a card per
address (every <ip>, each with its DHCP range dialog, which libvirt
takes on a stopped network); its fixed addresses of every subnet in
one table, searched, each with Edit and Delete, one dialog adding
and editing them; the VMs whose definition names it, connected or
configured, linked (wvmNetwork.get_vms, one domain listing, a VM
undefined meanwhile left out); its
bandwidth limits where libvirt sets them (not on macvtap or SR-IOV
networks), in KiB/s, from the saved definition with a note that a
running network takes them when restarted; its XML in an accordion.
The page reads the running and the saved definition once each, and
only to render itself: its actions, which all redirect, read nothing
of it first.
- The New network dialog is one form, as the New pool one: the type
as radio cards (the radio_card.html include, now shared by both),
the chosen type's fields only, IPv6 with its box, a bridge or
interface suggested from the host's (get_host_interfaces, not the
bridges libvirt made for its own networks); a refused network or
one libvirt refuses opens the dialog again with what was entered,
the reasons beside the fields and focus on the first.
- What the New pool and New network dialogs share is one script,
static/js/choice_dialog.js: the radio cards show their fieldsets
(data-kinds) and a refused form opens again focused on its first
refused field; each dialog keeps only its own changes.
- The fixed-address dialogs per family go to the page's own dialog.
- The state filter is a row of pills, All and each state, counting the
VMs the search finds (the chosen state aside); a state without any is
hidden unless chosen (All never), and a status line tells screen
readers how many VMs match. Every state keeps its pill.
- A labelled "New VM" button replaces the bare green plus; "Find IP"
says "Find IP / MAC", which it finds.
- States are badges; a shut-off VM is grey, not red: it is not a fault.
- A VM's cell holds its name, its title, and for those who see owners
its first owner as a badge, "+N" for the others (named for screen
readers and on hover); the separate user column goes.
- Each row has the same button group for a superuser or the VM's
owners, from the actions the user may use (states.allowed_actions),
all of it disabled on a VM an administrator paused; view-only users
get none. It holds Console, the power action
the state calls for (Start, Resume, Shut down, or Clone for a
template) and a menu of the others (Suspend, Force off, Power cycle),
what does not apply now disabled. The power button is an icon,
named on hover and for screen readers, so every group is as wide and
they line up from row to row; the power cut confirmations stay. On a
phone Console shows its icon only too.
- A grouped host's row has its name, a Connected or Not connected
badge, its VM count and a labelled host memory bar; an unreachable
host's row is table-warning. Its collapse control and the one for
all hosts are buttons, with aria-expanded kept.
- vCPUs and memory hide on a phone in both layouts, and table cells
keep Bootstrap's own padding there: Zephyr doubles it and a list's
last column no longer fit the screen.
- The search read a row's whole text, so a word on a button or in a
state label matched every row. VM rows now carry data-search (the
name, title and owners, and the host in the flat list), and
table_filter.js searches that text when a row has it; the state has
its own filter.
- Nothing matching left an empty table. table_filter.js shows the
page's #no-match while no row does; the VM list's says so and offers
"Clear the filters". A user with no VMs at all is told so instead of
an empty table.
- The grouped list's "#" toggled each host on its own: a host
collapsed by hand opened while the others closed. It now collapses
every host, or opens them all once all are collapsed.
- One alert names every host the panel cannot reach, with why, in
place of one dismissible alert per host; users who see no hosts keep
their own message.
- A host's VM list showed a VM's maximum memory, the Instances page
its current memory: both show the current memory now.
- The owners' users are prefetched with the VMs; the flat list's
Bootstrap 4 font-italic is fst-italic.
A key held from the menu (Hold Ctrl, Alt or Windows) is the same key as
the keyboard's left Ctrl, Alt or Windows key. Pressing and releasing
that key on the screen let the VM's key go, while the menu still showed
it held. And when the key went down outside the screen (in the
Clipboard dialog) and came up on it, noVNC sent no release, as it had
not seen the key go down.
The release of that key where noVNC takes keys (the screen, the touch
keyboard) now lets a held key go itself, and clears the menu's mark. A
release elsewhere reaches no VM and changes nothing.
"Type it" sent each character's keysym and let QEMU pick the key from
its own US map, with Shift added for the US shifted characters. A VM
on another layout got other characters: on Turkish Q, '"' typed 'İ',
'@' typed "'", and ğ, ü, ş, ı, ö, ç typed nothing.
The Clipboard dialog now asks for the VM's keyboard layout and
remembers it per browser. Each character is typed as the key that makes
it on that layout (its scancode), with Shift, AltGr or both (AltGr
first: pressed after Shift, the right Alt is Alt on the Linux console),
so the VM's own layout makes the character. The layout is fixed when
typing starts. Text with a character no key types on the layout is not
typed at all, and the dialog lists those characters: a password or a
command with a character left out would be a wrong one.
A layout is one file in console/layouts/: its name and, for each key,
the characters it types plainly, with Shift, with AltGr and with
Shift+AltGr. The view offers every file, US first. dev/console_layout.py
writes a file from the system's XKB data as libxkbcommon computes it
(through ctypes, no new dependency), mapping keys to DOM codes with
noVNC's table from QEMU's keycodemapdb; it lists the dead keys it leaves
out, and drops the keys the keyboard model lacks (the key left of Z on
US pc104 keyboards). English (US) and Turkish Q come with it; the
README says how to add one.
The serial page had a white strip of inline styles with an untranslated
status and a browser-default button above the terminal, sent input while
disconnected, sized the terminal only on window load and resize, and left
the keyboard elsewhere after the key menu. When a superuser opened a
console open in another window, its user saw "[An administrator opened
this console]" and a plain "disconnected".
- console-xterm.html shares the VNC page's bar: status badge (Connecting,
Connected, Disconnected, the server's refusal), Disconnect, then
Reconnect (a new page for a new token). The script is
static/js/console_serial.js; the token reaches it as json_script data.
- The terminal takes the keyboard on connect and after the key menu; input
is sent only while connected; it fits its box on connect and whenever
the box changes size (ResizeObserver).
- A console that writes nothing yet gets a dim local hint: press Enter.
- socketiod sends the displaced client "taken_over" with the superuser's
username; the page shows "Taken over by <name>" in the bar and the
terminal. The superuser is not asked first (owner's decision).
- Fullscreen uses the shared console_keys.js handler (keyboard lock).
The VM page offered a lite and a full VNC console. Lite lacked a clipboard,
display settings and a way to reconnect; full put noVNC's own side bar under
the panel's bar, with a Fullscreen item that called a function noVNC does
not have, status messages hidden behind the bar, saved noVNC settings that
overrode the Access tab's, connection settings that cannot apply, and a
Connect button that reused the page's two-minute token and failed.
console-vnc.html and static/js/console_vnc.js replace both, on noVNC's RFB
with Bootstrap controls, and keep what the full view did:
- Status in the bar (Connecting, Connected, Disconnected, Connection lost,
Could not connect, Authentication failed with the server's reason on
hover); Disconnect, then Reconnect, which loads the page again for a new
token.
- The VNC password in a dialog (with a username when the server asks for
one), not a browser prompt; without passwordless console it is not in
the page.
- Send key(s) gains Hold Ctrl / Alt / Windows (noVNC's extra keys).
- Clipboard: what the VM copies, sending text to the VM's clipboard, and
typing it key by key (new: works in firmware, installers and login
prompts; Shift for the characters a US keyboard shifts, 25 ms a key as
firmware drops faster keys, verified in a UEFI shell).
- View: scaling (none, fit, resize the VM's screen), clip, drag a clipped
screen, view only, dot cursor, quality, compression; it starts as
Settings > Console says (a touch screen starts fitted).
- A Keyboard item on touch devices (noVNC's on-screen keyboard input,
key events and Android's text-only input), Fullscreen with keyboard
lock, the bell.
Dropped with the full view: noVNC's websocket host/port/path, repeater ID
and log level (the panel fixes them), automatic reconnect (the token is
single use in time), XVP power buttons (QEMU has no XVP) and shared-mode off.
The bar is compact (about 45 px in the 850x600 window). The Access tab has
one Console button instead of the Lite/Full split and four switches, and
it and the VM list open one window per VM (opening it again reloads it).
The lite and the full console page each carried the same 150 lines that
send key combinations (Ctrl+Alt+Del, Ctrl+Alt+F1..F12, Alt+Tab, ...). They
now import static/js/console_keys.js, which binds the menu to the page's
RFB connection.
The list pages' search (filter-table.js) read what was typed as a
regular expression: a "(" or "[" stopped it with an error. It also
needed jQuery, while the instance list had its own script for the same
search. Both are now static/js/table_filter.js: plain text in any case,
the instance list's state list and host groups where a page has them,
remembered for a day as before. A group's header row is marked as one
(data-group-header) instead of being any row without a state.
The dialog filled its texts with String.replace, which reads $& and $'
in the replacement as patterns: a host named c$&1 showed as
c%(hosts)s1. The values now go in through a function, which inserts
them as they are.
The search's request was sent on to the login page, and the dialog said
"The search did not go through. Try again." The page now reloads, which
goes to the login form and back to the Instances page after signing in.
The "Find IP" dialog takes a MAC address (aa:bb:..., aa-bb-... or
aabb...) as well as an IP address or a network. A MAC finds the VMs with
a network card of that MAC, shut-off ones too (from their definitions),
with that card's addresses when the VM runs: for a MAC seen on a switch
port or in an external DHCP server's log. A MAC on more than one VM is
marked as a possible conflict. Only the VMs with that MAC are read, and
the card's link-local address, which comes from the MAC, is left out.
The Instances page's filters and the address search become one control:
the state list, the search box and a "Find IP" button. "Find IP" opens a
dialog (with the address typed in the search box, if any). An IP address
or a network (CIDR) finds the running VMs whose network cards use it,
read live from libvirt within 5 seconds: libvirt's DHCP leases, the host's
ARP table and the guest agent. Only addresses on the VM's own NICs count,
so interfaces inside the guest such as docker0 never match. Each match
shows the VM, its MAC, where the address came from, and a possible-
conflict mark when two VMs report one address. A coverage line says how
many running VMs were checked, how many had no connected guest agent (a
static address on them cannot be seen), which agents could not be read,
which hosts were not reached or not finished in time, and when it was
read.
The hosts are read in parallel: leases and ARP first, then each guest
agent on its own thread, so an agent that never answers holds back only
its own VM; libvirt waits for an agent without limit, so a search starts
only while its threads fit in 16 search threads in the worker.
Administrators search every compute, VMs the panel has not registered
yet included, and see the hosts; other users find only their own VMs and
see no hosts or host errors.
Found by review (Codex and agy) of the XML editor's dialog:
- A busy or moved VM made the page reload and the edit was lost. The
dialog's requests now get these answers as JSON (X-Requested-With, as the
create page's flavor forms) and show them; any other failure says the
edit is still in the editor.
- libvirt finds the VM to define by the XML's UUID: another VM's UUID
overwrote that VM past its lock, a new or missing one added a VM. The
XML must keep this VM's UUID; a malformed one is refused with the
parser's error, as on the create page.
- Save sends the XML whose diff the dialog shows, also when two previews
answer out of order; a failed save keeps the diff and Save.
- The edited XML is defined with the line breaks libvirt gave, not the
form's CRLF, and the VM's state is read before the definition, so a
failed read cannot turn a saved change into an error.
The XML editor of a running or paused VM only showed its XML. It now
shows the persistent definition, the one the VM starts with next (with
secrets, like the other edit forms), and Change saves it through the same
review dialog; the running VM keeps its live configuration until it
restarts. The tab and the saved message say so. The check against a
definition changed since the editor was opened covers this case too.
Change used to define the edited XML at once. It now opens a dialog with
the lines the edit changes in the VM's definition, and Save there defines
it. A definition libvirt refuses comes back to the dialog with the reason,
and the edit stays in the editor; before, the page reloaded with the
current XML and the edit was lost. A definition that changed since the
editor was opened (another tab, a disk added) is not overwritten: the
dialog asks to reload. An unchanged XML has nothing to save.
change_xml answers the dialog with JSON; the editor's script moves to
static/js/xml_editor.js.
sortable.js 0.8.0 (abandoned since 2014) sorted only a table's first
body: in the grouped VM list the first host's row moved among its VMs
and the other hosts never sorted, and memory sorted as text ("1024 MB"
before "512 MB"). tablesort 5.7.1 sorts each table body on its own and
keeps a row marked data-sort-method="none" in place, so hosts stay in
name order with their row on top and their VMs sort below it. Memory,
vCPUs and volume sizes sort by their numbers (data-sort). Headers are
reachable by keyboard and carry aria-sort.
base.html loads tablesort for every table marked data-sortable; the
per-page sortable includes and sortable-theme-bootstrap.css go, so these
tables take the theme's table style like the others. The grouped list's
row numbers go (meaningless once sorted). The VM owners and VM logs
tables were marked sortable but never loaded the script; they stay
unsorted.
The list gets a state selector beside the search box. The search now
matches plain text in any case (a '(' no longer breaks it), and in the
grouped list a host's name shows all of its VMs while a host row shows
only while one of its VMs does. The filter moves to
static/js/instance_filter.js with a Node test; the other lists keep
filter-table.js. Collapsing a host now sets a class on its table body
instead of each row's display, so a collapsed host and the filter no
longer undo each other.
@xterm/xterm 6.0.0 and @xterm/addon-fit 0.11.0 replace xterm 3.6.0; the page reads typed and pasted input with onData, and no longer writes every key and all terminal output to the browser console. The unused fullscreen addon goes.
The create wizard's image and network pickers use Tom Select 2.6.2 (its
Bootstrap 5 theme and checkbox list), which does not need jQuery;
bootstrap-multiselect calls $.isArray, which jQuery 4 removed. The
selected images and networks still fill the wizard's own lists.
Bootstrap SCSS, the JS bundle and the Bootswatch themes go from 5.3.3 to
5.3.8 (bug fixes only), and wvc-main.min.css is recompiled from zephyr.
Bootswatch now gives table text the body color, and Lux drops card and
modal header borders.
Tests compile every theme with the pinned libsass and check that the
shipped CSS is zephyr from these sources. The update and rollback steps
put back the two files a theme change rewrites, or git refuses to pull
over them.
Each stats answer carries a signed sample of the counters, bound to the VM,
its compute and UUID. The next poll sends it back and the rates are the
averages since then; a sample from another run of the VM (domain ID),
another host CPU count or device list, or older than 30 s falls back to
one second as before. Windows are measured on the monotonic clock.
Now that a poll is cheap, the Stats tab polls every 5 s like the host
graph, the first time as soon as it opens (pollWhileVisible takes the
delay of the first request).
A counter the host reports as unsupported (-1) or that went back gives no
value instead of 0 or a jump; a NIC without a target keeps its chart, a
pool volume disk is measured, and a disk or NIC attached after the page
loaded no longer stops the other charts. Disk rates are MB/s (they were
MiB/s labelled Mb/s), network Mbit/s; the CPU tooltip names the window.
Redirects to #access (root password, SSH key) and other top-level panes
opened nothing, and some sub-tab ids did not exist. static/js/instance_tabs.js
opens the pane and the tab that holds it from the page structure, and
opens Settings on its first section, without leaving the current tab;
guest OS info is loaded whenever it is the section opened. The bottom bar linked to
host pages, which only administrators may open, and showed host names to
everyone. A stray </li> is removed; the page's inline scripts and the tab
logic are checked with Node.
The VM page polls the VM state every 5 s and, while its Stats tab is
open, the statistics every 10 s; the compute overview polls the host
graph every 5 s. All used setInterval:
- A new request went out on schedule while the previous one was still
open. When a host goes silent, a stats request waits up to 30-45 s,
so each open page held several sync workers at once.
- Each time the Stats tab was shown, the page made new charts and a
new interval without stopping the old ones, and polling went on on
the other tabs of the page.
- Hidden pages kept polling at full rate.
Measured in a browser against a test server (old code / new): Stats tab
shown 4 times, 31 s on it: 12 / 2 requests; 31 s on another tab of the
page: 12 / 0; page hidden for 31 s: 15 / 0, and the new code asks once
right after the page is shown again; with 25 s answers, at most 15 / 1
requests open at once.
static/js/poll.js repeats a request while the page is visible: the
next one 5 or 10 s after the previous answer, none while hidden, one at
once when shown again. The Stats tab makes its charts once and polls
only while shown. The answer handler runs after the poller's own
bookkeeping, so an error in it (a chart for a disk added meanwhile)
does not stop the polling. A Node test of poll.js runs with the test
suite when node is installed.
