Allows WebContentClient to get pid of WebContent process right after
creation, so there is no window between forking and
notify_process_information() IPC response, when client doesn't know the
pid.
In the upcoming changes, we are going to switch macOS to using an
IOSurface for the backing store. This change will simplify the process
of sharing an IOSurface between processes because we already have the
MachPortServer running in the browser, and WebContent knows how to
locate the corresponding server.
This change ensures that if a screenshot is requested between teardown
of paintable tree and relayout, we will wait for layout to complete
before taking a screenshot.
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.
Previously, the "Find Next Match" and "Find Previous Match" actions
simply updated the match index of the last query to be performed. This
led to incorrect results if the page had been modified after the last
query had been run.
`Page::find_in_page_next_match()` and
`Page::find_in_page_previous_match()` both now rerun the last query to
ensure the results are up to date before updating the match index.
The match index is also reset if the URL of the active document has
changed since the last query. The current match index is maintained if
only the URL fragment changes.
This change allows the results of a find in page query to be reported
back to the user interface. Currently, the number of results found and
the current match index are reported.
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 allows searching for text with case-insensitivity. As this is
probably what most users expect, the default behavior is changes to
perform case-insensitive lookups. Chromes may add UI to change the
behavior as they see fit.
This allows the browser to send a query to the WebContent process,
which will search the page for the given string and highlight any
occurrences of that string.
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.
On Serenity, it's not trivial to extract the peer pid from a socket that
is created by SystemServer and then passed to a forked service process.
This patch adds an API to let the WebContent process notify the UI
directly, which makes the WebContent process show up in the Serenity
port's TaskManagerWidget. It seems that we will need to do something of
this sort in order to properly gather metrics on macOS as well, due to
the way that self mach ports work.
This adds an IPC for chromes to mute a tab. When muted, we trigger an
internal volume change notification and indicate that the user agent has
overriden the media volume.
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.
Instead of wrapping every entry in Optional, use the null state of the
style pointer for the same purpose.
This shrinks StyleProperties by 1752 bytes per instance.
Normally, assigning to e.g document.body.onload will forward to
window.onload. However, in a detached DOM tree, there is no associated
window, so we have nowhere to forward to, making this a no-op.
The bulk of this change is making Document::window() return a nullable
pointer, as documents created by DOMParser or DOMImplementation do not
have an associated window object, and so must be able to return null
from here.
Now that all input events are handled by LibWebView, replace the IPCs
which send the fields of Web::KeyEvent / Web::MouseEvent individually
with one IPC per event type (key or mouse).
We can also replace the ad-hoc queued input structure with a smaller
struct that simply holds the tranferred Web::KeyEvent / Web::MouseEvent.
In the future, we can also adapt Web::EventHandler to use these structs.
All of this error propogation came from a single call to
HashMap::try_ensure_capacity! As part of the ongoing effort to ignore
small allocation failures, lets just assert this works. This has the
nice side-effect of propogating out to a few other classes.
We had previous implemented some plumbing for file input elements in
commit 636602a54e.
This implements the return path for chromes to inform WebContent of the
file(s) the user selected. This patch includes a dummy implementation
for headless-browser to enable testing.
When a tab or nested traversable navigable is closed, there might be
messages still in the pipe from the UI process that we need to
gracefully drop, rather than crash trying to access an invalid pointer.
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.
When the WebContent process has painted to its shared bitmaps, it sends
a synchronous IPC to the browser process to let the chrome paint. It is
synchronous to ensure the WC process doesn't paint onto the backing
bitmap again while it is being displayed.
However, this can cause a crash at exit if the browser process quits
while the WC process is waiting for a response to this IPC.
This patch makes the painting logic asynchronous by letting the browser
process broadcast when it has finished handling the paint IPC. The WC
process will not paint anything again until it receives that message. If
it had tried to repaint while waiting for that message, that paint will
be deferred until it arrives.
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).
All DOM node mutation IPCs now invoke an async completion IPC after the
DOM is mutated. This allows consolidating where the Inspector updates
its view and the selected DOM node.
This also allows improving the response to removing a DOM node. We would
previously just select the <body> tag after removing a DOM node because
the Inspector client had no idea what node preceded the removed node.
Now the WebContent process can just indicate what that node is. So now
after removing a DOM node, we inspect either its previous sibling (if it
had one) or its parent.
Rename them from "did_get_*" to "did_inspect_*", to correspond to the
request methods "inspect_dom_tree" and "inspect_accessibility_tree". No
functional change, but this makes it a bit easier to stare at IPC files
side-by-side and know which response method corresponds to a request
method at a quick glance.
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.
