Implement bookmark import/export in about:bookmarks using Netscape
bookmark HTML in JavaScript.
Import parsed items into BookmarkStore under an "Imported Bookmarks"
folder, and treat internal WebUI about: pages as potentially
trustworthy so SecureContext APIs are available there.
Passing the browser command line and executable path to every WebContent
process just in case we load about:version always felt a bit weird. We
now use the WebUI framework to load this information on demand.
Synthesize an extra AutocompleteSuggestion at the top of the Search
Suggestions section whenever there is a configured search engine and
the typed query is not URL-shaped.
Use the query as the row's primary text, carry a "Search with <engine>"
subtitle, and render that subtitle in the AppKit and Qt popups so the
explicit search fallback stays visible and readable even when history
fills the list.
Some navigations report the same URL more than once through
WebContentClient::did_change_url(). Forwarding those duplicate updates
into the frontend turned an internal no-op into visible UI churn,
including location bar resets and AppKit focus stealing.
Treat repeated URL notifications as a no-op inside LibWebView so
frontends only react to real URL changes.
Route the existing Clear Browsing Data dialog through HistoryStore's
time-range deletion path as well. That makes the Settings action
remove visited pages from persisted history and from history-backed
address bar suggestions instead of only touching cache and site data.
Add a history checkbox to the dialog, thread its state through the
Settings WebUI message, and cover remove_entries_accessed_since() for
both transient and persisted stores in TestHistoryStore.
Replace the frontend-facing Vector<String> flow with structured
AutocompleteSuggestion objects carrying source, section, title,
and favicon metadata.
Build merged history and literal-URL rows in LibWebView, deduplicate
equivalent URL suggestions, move the autocomplete URL helpers out
of URL.h, and update the history and URL tests around the new model.
Record visits as soon as a page produces useful metadata such as a
title or favicon so pages that never finish loading still become
autocomplete candidates.
Store favicons in the history schema from the start instead of
introducing an upgrade path inside this series, and cover persisted
metadata behavior in TestHistoryStore.
Teach LibWebView autocomplete to query HistoryStore before falling back
to remote engines and move the wiring out of the AppKit frontend.
Refine matching so scheme and www. boilerplate do not dominate results,
short title and substring queries stay quiet, and history tracing can
explain what the ranking code is doing.
Add a HistoryStore abstraction with transient and persisted backends,
normalize recorded URLs, and skip non-browsable schemes.
Cover lookup and persistence in TestHistoryStore so history-driven
features can share one backend.
Route BroadcastChannel messages over IPC so matching channels can
receive them across WebContent and WebWorker processes, rather than only
within a single process.
Each channel now serializes its payload, sends it upward over IPC, and
receiving processes deliver it locally after matching by storage key and
channel name.
Now that we detect and handle child processes exiting, we should see
less "Trying to post_message during IPC shutdown" VERIFY failures that
crash the UI process.

There is no direct equivalent to SIGCHILD on Windows. The closest we
can get is monitoring a specific process, given a known pid. On Unix
there is no single solution to be able to do that in LibCore's
EventLoopImplementationUnix. For Linux there's a SYS_pidfd_open syscall
that can integrate into poll(), but on macOS a kqueue would be needed.
Given macOS uses EventLoopImplementationUnix for the headless view
implementation, we currently can't create a fully cross-platform
abstaction at the Event Loop level to match what Windows needs to do.
ProcessMonitor's purpose is to abstract away the Unix vs Windows
behaviour avoiding more inlined ifdef soup in ProcessManager.
Track the last modification time on every BookmarkItem. The timestamp
is updated when editing a bookmark or folder, moving an item, or
updating a favicon. This aligns with the Netscape bookmark HTML format
used by Chromium and Firefox for bookmark export/import
(LAST_MODIFIED attribute).
Store a creation timestamp on every BookmarkItem, for both bookmarks
and folders.
This aligns with the Netscape bookmark HTML format used by Chromium
and Firefox for bookmark export/import (ADD_DATE attribute).
Previously, `--headless=screenshot` always took a screenshot after 1
second. This option allows the user to specify the number of seconds to
wait before taking the screenshot.
This page renders the bookmarks as a tree and hook context menu events
up to the UI's bookmarks bar context menus to allow editing bookmarks.
Users can also drag-and-drop bookmark items around.
Generalize the backing store sharing abstraction into SharedImage, which
represents shared GPU memory independently of Skia and can be used to
share memory between different processes or different GPU contexts.
When a page opens a popup, the child tab shares the parent's
WebContent process via initialize_client_as_child(). Both tabs
register as views on the same WebContentClient.
If the child tab then does a cross-site navigation,
create_new_process_for_cross_site_navigation() would call
unregister_view() (correct) and then unconditionally send
CloseServer (wrong). This killed the WebContent process even
though the parent tab was still using it.
The unconditional async_close_server() predates the shared-process
popup model. It is no longer needed since unregister_view() already
sends CloseServer when the last view is removed.
Move MachPortServer from LibWebView into LibIPC as MachBootstrapListener
and move the Mach message structs from MachMessageTypes.h into LibIPC.
These types are IPC infrastructure, not UI or platform concerns.
Consolidating them in LibIPC keeps the Mach bootstrap handshake
self-contained in a single library and removes LibWebView's dependency
on LibThreading.
Previously, the bootstrap handshake used a two-state machine
(WaitingForPorts / WaitingForReplyPort) to handle a race: the parent
registering transport ports and the child sending a bootstrap request
could arrive in either order, so whichever came first stored its half
and the second completed the handshake.
Eliminate the race by holding a mutex across spawn() and
register_child_transport(). Since the child cannot send a bootstrap
request before it exists, and the lock isn't released until its
transport is registered, handle_bootstrap_request() is guaranteed to
find the entry. This reduces the pending map to a simple pid-to-ports
lookup and collapses the two-variant state into two straightforward
branches: known child, or on-demand (non-child) caller like WebDriver.
This patch adds BookmarkStore to manage bookmarks stored in a JSON file
in the application settings directory. It supports both folders and
bookmarks. It does not yet support arbitrary editing of bookmarks, other
than updating stored favicons.
Now that LibIPC uses Mach ports for transport on macOS, IOSurface port
rights can be sent as regular IPC message attachments instead of through
a separate ad-hoc Mach message side-channel. Introduce
Web::SharedBackingStore that wraps either a MachPort (macOS) or
ShareableBitmap (other platforms) with IPC encode/decode support,
unifying backing store allocation into the existing
did_allocate_backing_stores IPC message.
Registering multiple Mach port names with the bootstrap server at
runtime is not how macOS expects it to be used — the bootstrap server
is meant for static services, and the only reason we used it originally
was so child processes could reach back to the UI process.
Remove bootstrap_transport_over_socket(), which had both sides register
dynamic names with the bootstrap server and exchange them over a socket.
Instead, WebDriver and BrowserProcess connections now go through
MachPortServer instances directly. When a non-child process contacts a
MachPortServer, the server creates a port pair on demand (detected via
sysctl ppid check) and returns the local half immediately. This keeps
bootstrap server usage limited to the one original case: child processes
looking up their parent's MachPortServer.
WebDriver Session now runs its own MachPortServer per session.
--webdriver-content-path becomes --webdriver-mach-server-name on macOS.
Spare WebContent launches are skipped when a WebDriver session is active
to avoid bootstrap races.
On macOS, use Mach port messaging instead of Unix domain sockets for
all IPC transport. This makes the transport capable of carrying Mach
port rights as message attachments, which is a prerequisite for sending
IOSurface handles over the main IPC channel (currently sent via a
separate out-of-band path). It also avoids the need for the FD
acknowledgement protocol that TransportSocket requires, since Mach port
right transfers are atomic in the kernel.
Three connection establishment patterns:
- Spawned helper processes (WebContent, RequestServer, etc.) use the
existing MachPortServer: the child sends its task port with a reply
port, and the parent responds with a pre-created port pair.
- Socket-bootstrapped connections (WebDriver, BrowserProcess) exchange
Mach port names over the socket, then drop the socket.
- Pre-created pairs for IPC tests and in-message transport transfer.
Attachment on macOS now wraps a MachPort instead of a file descriptor,
converting between the two via fileport_makeport()/fileport_makefd().
The LibIPC socket transport tests are disabled on macOS since they are
socket-specific.
MultiServer was inherited from SerenityOS where it was used in many
places. Now that BrowserProcess is its only consumer, inline the
connection acceptance logic directly into BrowserProcess and remove
the abstraction.
Delete Lexer.cpp/h and Token.cpp, replacing all tokenization with a
new rust_tokenize() FFI function that calls back for each token.
Rewrite SyntaxHighlighter.cpp and js.cpp REPL to use the Rust
tokenizer. The token type and category enums in Token.h now mirror
the Rust definitions in token.rs.
Move is_syntax_character/is_whitespace/is_line_terminator helpers
into RegExpConstructor.cpp as static functions, since they were only
used there.
