This change adds a `--use-lagom-networking` flag to the WebWorker
process. Qt networking is used if this flag isn't passed. The flag is
passed the UI launches the WebWorker process unless the Qt chrome is
being run with the `--enable-qt-networking` flag.
GPU painter that uses AccelGfx is slower and way less complete compared
to both default Gfx::Painter and Skia painter. It does not make much
sense to keep it, considering Skia painter already uses Metal backend on
macOS by default and there is an option to enable GPU-accelerated
backend on linux.
This call is used to inform the chrome that it should display a tooltip
now and avoid any hovering timers. This is used by <video> tags to
display the volume percentage when it is changed.
Now instead of sending the position in which the user entered the
tooltip area, send just the text, and let the chrome figure out how to
display it.
In the case of Qt, wait for 600 milliseconds of no mouse movement, then
display it under the mouse cursor.
By Setting setBordered propperty on header buttons to `Yes` this
path makes the whole button clickable. Previously the only the
icon was clickable, now it's easy to click.
This large commit also refactors LibWebView's process handling to use
a top-level Application class that uses a new WebView::Process class to
encapsulate the IPC-centric nature of each helper process.
In the upcoming changes, Skia painter will be switched to Metal backend,
so we can no longer assume `pitch = width * 4` while reading Gfx::Bitmap
that wraps IOSurface populated by writing into MTLTexture that has
padded scanlines.
This is the same behavior as RequestServer, with the added benefit that
we know how to gracefully reconnect ImageDecoder to all WebContent
processes on restart.
Using mmap-allocated memory for backing stores does not allow us to
benefit from using GPU-accelerated painting, because all the performance
increase we get is mostly negated by reading the GPU-allocated texture
back into RAM, so it can be shared with the browser process.
With IOSurface, we get a framebuffer that is both shareable between
processes and can be used as underlying memory for an OpenGL/Metal
texture.
This change does not yet benefit from using IOSurface and merely wraps
them into Gfx::Bitmap to be used by the CPU painter.
This patch adds a simple in-memory HTTP cache to each WebContent
process.
It's currently off by default (turn it on with --enable-http-cache)
since the validation logic is lacking and incomplete.
This adds a motion preference to the browser UI similar to the existing
ones for color scheme and contrast.
Both AppKit UI and Qt UI has this new preference.
The auto value is currently the same as NoPreference, follow-ups can
address wiring that up to the actual preference for the OS.
This makes WebView::Database wrap around sqlite3 instead of LibSQL. The
effect on outside callers is pretty minimal. The main consequences are:
1. We must ensure the Cookie table exists before preparing any SQL
statements involving that table.
2. We can use an INSERT OR REPLACE statement instead of separate INSERT
and UPDATE statements.
The main intention of this change is to have a consistent look and
behavior across all scrollbars, including elements with
`overflow: scroll` and `overflow: auto`, iframes, and a page.
Before:
- Page's scrollbar is painted by Browser (Qt/AppKit) using the
corresponding UI framework style,
- Both WebContent and Browser know the scroll position offset.
- WebContent uses did_request_scroll_to() IPC call to send updates.
- Browser uses set_viewport_rect() to send updates.
After:
- Page's scrollbar is painted on WebContent side using the same style as
currently used for elements with `overflow: scroll` and
`overflow: auto`. A nice side effects: scrollbars are now painted for
iframes, and page's scrollbar respects scrollbar-width CSS property.
- Only WebContent knows scroll position offset.
- did_request_scroll_to() is no longer used.
- set_viewport_rect() is changed to set_viewport_size().
This was no longer doing anything. We'll eventually want a way to pass
system default fonts to each WebContent process, but we don't need to
squeeze everything through this API that was really meant for Serenity's
very idiosyncratic font system.
This is to avoid including any LibProtocol header in Objective-C source
files, which will cause a conflict between the Protocol namespace and a
@Protocol interface.
See Ladybird/AppKit/Application/ApplicationBridge.cpp for why this
conflict unfortunately cannot be worked around.
Now that the chrome process is a singleton on all platforms, we can
safely add a cache to the CookieJar to greatly speed up access. The way
this works is we read all cookies upfront from the database. As cookies
are updated by the web, we store a list of "dirty" cookies that need to
be flushed to the database. We do that synchronization every 30 seconds
and at shutdown.
There's plenty of room for improvement here, some of which is marked
with FIXMEs in the CookieJar.
Before these changes, in a SQL database populated with 300 cookies,
browsing to https://twinings.co.uk/ WebContent spent:
19,806ms waiting for a get-cookie response
505ms waiting for a set-cookie response
With these changes, it spends:
24ms waiting for a get-cookie response
15ms waiting for a set-cookie response
This actually actives the underlying tab if needed. This wasn't an issue
previously, as new tabs were always created in already active windows.
But when new windows/tabs are requested from new Ladybird processes, we
need to actually activate those tabs.
For some reason, we occasionally receive a junk `info` pointer from the
CFSocketCallback we create for socket notifiers. Instead of capturing a
pointer to the local Core::Notifier for this `info` member, grab it from
the thread data instance based on the socket FD.
This was mostly seen when spamming new window requests to an existing
Ladybird process.
When we receive a LibCore event, we post an "application defined" Cocoa
event to the NSApp. However, we are currently only processing these from
`pump`, which is only invoked manually.
Instead, we should listen for the event that we've posted and process
the event queue at that time. This is much closer to how Qt's event loop
behaves as well with EventLoopImplementationQtEventTarget.
This really only affects headless-browser when it is linked with Qt. In
that case, it currently uses Qt networking by default and does not have
a flag to use RequestServer instead. Change the default to use RS so it
can undergo sanitized testing in CI.
It previously resided in LibWebView to hide the details of launching a
singleton process. That functionality now lives in LibCore. By moving
this to Ladybird, we will be able to register the process with the task
manager.
When running with --log-all-js-exceptions, we will print the message
and backtrace for every single JS exception that is thrown, not just
the ones nobody caught.
This can sometimes be very helpful in debugging sites that swallow
important exceptions.
The previous name was extremely misleading, because the call is used for
pushing or replacing new session history entry on chrome side instead of
only changing URL.
Currently the `<select>` dropdown IPC uses the option value attr to
find which option is selected. This won't work when options don't
have values or when multiple options have the same value. Also the
`SelectItem` contained so weird recursive structures that are
impossible to create with HTML. So I refactored `SelectItem` as a
variant, and gave the options a unique id. The id is send back to
`HTMLSelectElement` so it can find out exactly which option element
is selected.
We already display a speaker icon on tabs which are playing audio. This
allows the user to click that icon to mute the tab, at which point the
icon is replaced with a muted speaker icon.
We would previously hide the icon when audio stopped playing. We now do
this only if the tab isn't muted. If it is muted, the muted speaker icon
remains on the tab so that the page isn't stuck in a muted state.
When audio begins playing, add a button as an accessory view with a
speaker icon to indicate which tab is playing audio. This button is
currently disabled, but in the future may be used to mute the tab.
This URL library ends up being a relatively fundamental base library of
the system, as LibCore depends on LibURL.
This change has two main benefits:
* Moving AK back more towards being an agnostic library that can
be used between the kernel and userspace. URL has never really fit
that description - and is not used in the kernel.
* URL _should_ depend on LibUnicode, as it needs punnycode support.
However, it's not really possible to do this inside of AK as it can't
depend on any external library. This change brings us a little closer
to being able to do that, but unfortunately we aren't there quite
yet, as the code generators depend on LibCore.
The AppKit chrome currently handles all input events before selectively
forwarding those events to WebContent. This means that WebContent does
not see events like cmd+c.
Here, we make use of LibWebView's input handling and wait for LibWebView
to inform the chrome that it should handle the event itself.
The IPC layer between chromes and LibWeb now understands that multiple
top level traversables can live in each WebContent process.
This largely mechanical change adds a billion page_id/page_index
arguments to make sure that pages that end up opening new WebViews
through mechanisms like window.open() still work properly with those
extra windows.
Instead of spawning these processes from the WebContent process, we now
create them in the Browser chrome.
Part 1/N of "all processes are owned by the chrome".
These IPCs are different than other IPCs in that we can't just set up a
callback function to be invoked when WebContent sends us the screenshot
data. There are multiple places that would set that callback, and they
would step on each other's toes.
Instead, the screenshot APIs on ViewImplementation now return a Promise
which callers can interact with to receive the screenshot (or an error).
With this change, chrome no longer has to ask the WebContent process
to paint the next frame into a specified bitmap. Instead, it allocates
bitmaps and sends them to WebContent, which then lets chrome know when
the painting is done.
This work is a preparation to move the execution of painting commands
into a separate thread. Now, it is much easier to start working on the
next frame while the current one is still rendering. This is because
WebContent does not have to inform chrome that the current frame is
ready before it can request the next frame.
Additionally, as a side bonus, we can now eliminate the
did_invalidate_content_rect and did_change_selection IPC calls. These
were used solely for the purpose of informing chrome that it needed to
request a repaint.
This commit un-deprecates DeprecatedString, and repurposes it as a byte
string.
As the null state has already been removed, there are no other
particularly hairy blockers in repurposing this type as a byte string
(what it _really_ is).
This commit is auto-generated:

It was a bit short-sighted to combine the tag and attribute names into
one string when the Inspector requests a context menu. We will want both
values for some context menu actions. Send both names, as well as the
attribute value, when requesting the context menu.
