This is a hack needed to preserve current behaviour after making set
viewport_rect() being not async in upcoming changes.
For example both handle_mousedown and handle_mouseup should use the same
viewport scroll offset even though handle_mousedown runs focusing steps
that might cause scrolling to focused element:
- handle_mousedown({ 0, 0 })
- run_focusing_steps()
- set_focused_element()
- scroll_into_viewport() changes viewport scroll offset
- handle_mouseup({ 0, 0 })
The DocumentTimeline constructor used the current millisecond time to
initialize its currentTime, but that means that a newly created timeline
would always have a different time value than other timelines that have
been through the update_animations_and_send_events function.
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.
Although refreshing is cheap, it was performed before each hit-testing
and was 2-4% in profiles on Discord and Twitter.
Now clip and scroll states are refreshed only if scroll offset has
changed.
EventSource allows opening a persistent HTTP connection to a server over
which events are continuously streamed.
Unfortunately, our test infrastructure does not allow for automating any
tests of this feature yet. It only works with HTTP connections.
The if statement in the dispatch implies we are in the idle state, so of
course the active time will always be undefined. If this was cancelled
via a call to cancel(), we can save the time at that point. Otherwise,
just send 0.
I saw a null pointer dereference here on GitHub once, but don't know how
to reproduce, or how we'd get here. Nevertheless, null-checking the
navigable is reasonable so let's do it.
This patch fixes two issues:
- Animation events that should go to the target element now do
(some were previously being dispatched on the animation itself.)
- We update the "previous phase" and "previous iteration" fields of
animation effects, so that we can actually detect phase changes.
This means we stop thinking animations always just started,
something that caused each animation to send 60 animationstart
events every second (to the wrong target!)
This returns the secondary target of a mouse event. For `onmouseenter`
and `onmouseover` events, this is the EventTarget the mouse exited
from. For `onmouseleave` and `onmouseout` events, this is the
EventTarget the mouse entered to.
Implement this function to the spec, and use the full blown URL parser
that handles blob URLs, instead of the basic-url-parser.
Also clean up a FIXME that does not seem relevant any more.
Previously, we would apply any adopted style sheet to the document if
its alternate flag was not set. This meant that all adopted style
sheets would be applied, since constructed style sheets never have this
flag set.
This was resulting in a whole lot of rebuilding whenever a new IDL
interface was added.
Instead, just directly include the prototype in every C++ file which
needs it. While we only really need a forward declaration in each cpp
file; including the full prototype header (which itself only includes
LibJS/Object.h, which is already transitively brought in by
PlatformObject) - it seems like a small price to pay compared to what
feels like a full rebuild of LibWeb whenever a new IDL file is added.
Given all of these includes are only needed for the ::initialize
method, there is probably a smart way of avoiding this problem
altogether. I've considered both using some macro trickery or generating
these functions somehow instead.
The following command was used to clang-format these files:
clang-format-18 -i $(find . \
-not \( -path "./\.*" -prune \) \
-not \( -path "./Base/*" -prune \) \
-not \( -path "./Build/*" -prune \) \
-not \( -path "./Toolchain/*" -prune \) \
-not \( -path "./Ports/*" -prune \) \
-type f -name "*.cpp" -o -name "*.mm" -o -name "*.h")
There are a couple of weird cases where clang-format now thinks that a
pointer access in an initializer list, e.g. `m_member(ptr->foo)`, is a
lambda return statement, and it puts spaces around the `->`.
The only subclass was already GC-allocated, so let's hoist the JS::Cell
inheritance up one level. This ends up simplifying a bit of rather
dubious looking code where we were previously slicing ESOs.
Seems like a specification bug, but other browsers update url before
popstate event is fired and so should we.
Fixes back/forward navigation on GitHub.
We were inadvertently keeping all documents alive by installing a
console client for them. This patch fixes the issue by adding a
finalizer to Document, and having that be the way we detach console
clients. This breaks the cycle.
With this change, we can spam set .innerHTML in a loop and memory
usage remains stable.
Fixes#14612
Changes the signature of queue_global_task() from AK:Function to
JS::HeapFunction to be more clear to the user of the function that this
is what it uses internally.
There were two things going wrong here:
- Transformed text (via CSS text-transform) was not invalidated after a
`@media` rule changed state.
- Removing the `style` attribute from an element didn't trigger a style
update.
This fixes the regression in subtest 46 of Acid3.
Fixes#21777
This change adds the `clear()`, `captureEvents()` and `releaseEvents()`
methods to the document object. These methods are obsolete, but are
still included in the HTML specification, which says they must do
nothing.
Before this change JS console was initialise from
activate_history_entry() which is too late for about:blank documents
that are ready to run scripts immediately after creation.
If initial src of an iframe is "about:blank", it does synchronous
navigation that is not supposed to be interleaved by other navigation
or usage of Document.open().

A bunch of this is leftover from pre porting over to new AK::String.
For example, for functions which previously took a ByteString const&
now accepting a StringView.
