Disable Qt quit-on-last-window behavior on macOS and install an
application-level menu so useful commands remain available after the
last browser window closes.
Reuse shared application actions and menus for Settings, Bookmarks,
History, Help, and global appearance controls. Centralize window-aware
commands such as New Tab, New Window, Open File, Open Location, and
Reopen Recently Closed so the browser window and windowless app menu
use the same behavior. Keep the location editor focused for new blank
windows after the native window has been activated.
The Storage panel expects storesUpdate messages after watched storage
changes. Summarize committed IndexedDB mutation logs into DevTools paths
and forward them through WebContent so Firefox can refresh database,
object-store, and record rows without polling.
Firefox's behaviour is less than ideal here. A lot of things don't
update automatically even inspecting a page in Firefox. Some
things (like new databases) won't show up until you fully refresh the
page. So that makes it a bit hard to know that we're doing things
correctly. As far as I can tell, we are at least behaving as well as
Firefox requires.
We do have one workaround: Firefox doesn't display record updates
without a manual refresh, and in fact any change messages for them show
up as rows in the host's database table. So for now, we filter them out
to avoid visual weirdness in the inspector.
Firefox asks the storage watcher for an indexed-db resource before it
shows IndexedDB entries in the Storage panel. Add an IndexedDB actor and
serialize the live LibWeb database registry on demand, so WebContent can
return the host tree and table rows without duplicating database state.
Use the LibWeb inspection helpers to read IndexedDB internals, and keep
the Firefox protocol shape in LibDevTools. WebContent only forwards the
serialized response over the existing DevTools IPC path.
Previously, the "View History" action always opened a new tab. We now
switch to an existing `about:history` tab when one exists in the active
window and fall back to opening a new tab otherwise.
Apply helper process sandboxing by default and replace the old
--enable-sandbox switch with --disable-sandbox. Propagate the opt-out
from Ladybird, test-web, and WebDriver to WebContent, WebWorker,
RequestServer, ImageDecoder, and Compositor.
Apply pinch zoom deltas to the compositor's visual viewport transform
so the currently presented display list can respond without waiting for
the WebContent main thread. Keep the normal WebContent pinch event path
so the real VisualViewport state and DOM-visible events catch up after.
Only take the compositor path when async scrolling is enabled and there
are no blocking wheel listeners, since pinch zoom dispatches a synthetic
wheel event that script may cancel. Coalesce queued pinch events in
WebContent so main-thread catch-up can adopt multiple gesture deltas
together.
Use the compositor visual viewport transform for wheel hit testing and
consume wheel deltas as visual viewport pan while zoomed. Scale the
handoff to layout viewport scrolling by the inverse visual viewport
scale, so touchpad momentum does not jump when the visual viewport hits
an edge.
Use the LibWebView history mirror to preserve traversable session
history across WebContent process swaps. WebContent reports snapshots to
the UI process, and new renderers can be seeded from the mirror.
Browser back and forward now resolve through the UI-owned used history
steps. WebContent still runs the spec traversal path when the current
renderer has enough matching state to do so.
Handle canceled and no-op UI navigations without leaving speculative
history entries or pending WebDriver waits behind. Preserve traversal
precheck state across synchronous IPC shutdown, and avoid overwriting a
restored target entry's persisted scroll state before the document has
adopted that entry.
Firefox sends the same storage actor mutation requests for Web Storage
that it uses for cookies. Handle addItem, editItem, removeItem, and
removeAll for localStorage and sessionStorage actors.
Apply the changes through the browser-process storage jar and emit the
matching store update packets so the Storage panel stays current after a
DevTools-initiated edit.
Firefox keeps the Storage panel current by sending store update packets
when localStorage or sessionStorage changes. Forward successful Web
Storage mutations to the storage actors and emit the matching update or
clear packet.
Use listener IDs for storage updates so the local and session storage
actors can subscribe independently.
Firefox exposes localStorage and sessionStorage through the same
storage actor protocol used by cookies. Add matching resources for the
current tab so the Storage panel can list key/value pairs.
Read the values through WebContent rather than directly from the
browser process. Session storage lives in LibWeb, and using the same
path for both stores keeps the actor independent of the backing store.
DevTools needs to edit and delete cookies from the browser process. Add
a small mutation surface to CookieJar and expose it through the DevTools
delegate while preserving the existing cookie notification path.
Firefox keeps the Storage table current through storesUpdate messages
from the storage actor. Forward browser cookie change notifications to
the cookies actor and classify visible rows against a fresh cookie
snapshot.
The existing cookie-change notifications report cookies that are
relevant to a specific page, whereas DevTools wants all cookies
relevant for a host, so we end up having to provide two different sets
of cookies to `notify_cookies_changed()`.
Firefox asks the cookies actor for rows after selecting a Storage host.
Read the browser cookie jar through the DevTools delegate and serialize
matching cookies with the fields Firefox expects.
This keeps mutation support disabled, but makes existing cookies visible
in the Storage panel.
This currently just contains a menu item to open about:history. But in
the future, we can add a list of recently closed / recently visited
pages as well.
Add --enable-sandbox to Ladybird and test-web, pass it through to
ImageDecoder, and make ImageDecoder install its Linux sandbox only when
the option is present.
The Linux implementation enables no_new_privs, configures glibc malloc
to avoid late CPU-count probes in helper threads, applies an empty
Landlock ruleset when available, and installs a seccomp filter for the
helper IPC, shared memory, threading, and decoding syscalls.
Deny plain read-only filesystem probes without granting file access, so
common runtime feature checks can observe the sandbox instead of
terminating the helper during normal decoding.
Add an explicit initializer for process-lifetime event loops and use it
for browser, helper service, and utility main loops. This preserves weak
event loop references for cross-thread users while making main thread
loop lifetime independent of normal program teardown.
Extend the existing DOM node inspection request with an options payload
and carry it through the browser process, WebView, IPC, and WebContent.
This lets later DevTools requests forward Firefox's top-level flags
without changing any inspected-node behavior yet.
We currently use LibWebView's Application as the entry point to learn
about the bookmarks bar being shown/hidden, and propagate that through
virtual methods. At the time this was added, AppKit's Tab window and
Qt's BrowserWindow did not have a settings observer. They do now, so
let's skip a couple of middle-men.
For AppKit, we change the settings observer to just (weakly) store the
Tab instance so that we don't have to add callback functions for each
setting.
We currently just log an "open" failure from LibMain with no extra info.
Even once the source is discovered, the user then has no way to fix the
issue other than to manually find and edit the settings JSON. Let's log
the error and move on.
Firefox's remote toolbox exposes an editable URL field for tab
descriptors. Submitting that field sends navigateTo to the tab
descriptor rather than the frame target.
Handle the request in the tab actor, route it through the DevTools
delegate, and reuse WebView's URL sanitizing and load path. Add protocol
coverage so the toolbar navigation request stays wired up.
Firefox's inspector toolbar sends goBack and goForward requests to the
tab descriptor when the descriptor advertises navigation support. Thread
those requests through the DevTools delegate and reuse the existing
WebView session-history traversal path.
Keep the legacy frame-target requests working too, matching Firefox's
window-global target compatibility surface. Add protocol coverage for
both entry points so the advertised trait and deltas stay locked down.
Firefox reloads remote targets through the tab descriptor's
reloadDescriptor request. We advertised support for that request, but
left it unhandled, so Firefox could clear inspector state without
causing Ladybird to reload the page.
Route reloadDescriptor, and the legacy frame target reload request,
through the DevTools delegate to WebView's reload path. This lets the
existing navigation notifications publish the replacement inspector root
after the reload completes.
This adds a setting to enable vertical tabs and to expand/collapse them
if enabled. This setting is hidden for UIs that do not support them
(which is every UI as of this commit).
Compositor recovery recreated contexts and replayed viewport sizes,
but it left the restarted helper with the default display metadata. A
recovered context could fall back to a 60 Hz timer instead of the
window's current display id and refresh rate until the frontend later
observed a screen change.
Store the display id in the shared view state, alongside the existing
maximum frame rate, and replay both values while restoring view state
after reconnect.
Page-presenting compositor contexts still carried a separate tagged ID
namespace and Browser-side page/context maps even though page IDs are
now allocated globally by the UI process. That made context
registration keep two ways to describe the same relationship and
forced compositor IPC to pass an extra presentation bit.
Use each page ID directly as its page-presenting compositor context ID
and allocate non-page compositor contexts from the same Browser-owned
counter. The registration path now sends only the optional page ID, and
Compositor infers client presentation from that page ID.
Page IDs were allocated independently by each WebContent PageHost,
starting at zero for every process. That made them unsuitable as a
global identity for page-presenting compositor contexts, because the
same numeric page ID could exist in multiple WebContent processes.
Move page ID allocation to WebView::Application and initialize each
WebContent process with its browser-assigned first page ID over IPC.
New view requests now get a browser-assigned page ID before
WebContent creates the PageClient, and PageHost no longer owns a
local page counter.
This gives page-presenting compositor contexts a stable global page
identity, which will allow their context IDs to be derived from page
IDs and simplify compositor context allocation in a follow-up.
Add a debug-menu toggle for caret hit testing at the mouse position.
Paint the insertion rect and log the result so selection bugs can be
inspected without temporary probes.
Request frames and repaint invalidation when the overlay state changes.
Also repaint when the caret rect moves within the same text node.
When an HTTPS response carries a Strict-Transport-Security header, the
received policy is now respected. Subsequent HTTP requests to a known
HSTS host are upgraded to HTTPS before the fetch algorithm makes
further decisions such as CORS and mixed content.
Fixes tpexpress.co.uk, where an XHR redirects HTTPS -> HTTP -> HTTPS,
relying on a HSTS policy received on the document response to avoid the
CORS failure.
LibWebView owns the active page connection and bridges the DevTools
delegate to WebContent. Track picker state there, translate UI hover,
preview, pick, and cancel requests into hit-test IPC, and forward the
resulting node ids back through the DevTools callback.
Keeping the request bookkeeping in LibWebView also lets the platform UI
frontends share the same picker behavior.
As we approach an alpha release, it will generally make less sense to
show all of the debug options in the application menu. Add a persistent
setting to show this menu, disabled by default.
The browser process forwards the maximum frame rate to WebContent, but
the compositor process had no copy of that display timing metadata or
the display identity needed by compositor-local vsync.
Add one compositor control IPC message carrying the optional display ID
and refresh rate together, and store both values on each compositor
context.
CompositorState treats presence in m_contexts as the lifetime state
for a compositor context. create_context() creates the entry and
destroy_context() removes it, so ContextState::is_registered duplicated
the map membership invariant.
The top-level-traversable bit was also duplicate information. The
only compositor use was backing-store padding while a window resize is
in progress, and page-presenting contexts are already identified by
PagePresentationRegistration::Yes. Normalize resize-in-progress to No
for non-page-presenting contexts, then remove the flag from
CompositorState, the backing-store API, and the compositor IPC boundary.
Commit 218d82cb65 added support for
pasting text with the middle mouse button. But primary pasting is
actually meant to interact with the "selection" clipboard, not the
text clipboard.
Add IPC structures and requests for inspecting grid layout data from
WebContent.
WebView forwards the async replies to LibDevTools and exposes the grid
highlighter hooks used by the protocol layer.
Parse Firefox grid highlighter options in WebContent and store them with
the active grid highlight.
Browser UI input can race with compositor context teardown during tab
close. The control connection may ask the compositor to handle, scroll,
or forward a mouse event after WebContent has already destroyed the
context. Treating that as an invariant crashes the compositor even
though the event is stale.
Make the UI-facing mouse handling and async scroll entry points return
false when the context is gone. Mouse forwarding now reports whether it
actually dispatched the event, letting LibWebView fall back to direct
WebContent IPC and preserve the normal input-event acknowledgement flow.
Remove the command-line option that allowed Browser to start
WebContent with the in-process compositor thread instead of the
Compositor helper process. The compositor process is now the default
path, so the opt-out flag and the matching WebContent selector only kept
the old thread mode reachable.
With that option gone, simplify Browser and WebContent startup to wire
each WebContent process to the Compositor process directly. The old
local Browser-to-WebContent compositor IPC setup and its fallback input
and ready-to-paint branches are no longer needed.
