Resolves a performance regression from
8ba18dfd40, where moving paint scheduling
to `EventLoop::process()` led to unnecessary repaints.
This update introduces a flag to trigger repaints only when necessary,
addressing the issue where repaints previously occurred with each event
loop process, irrespective of actual changes.
Change `EventHandler::handle_keydown()` to no longer assume the cursor
position's node is always a `DOM::Text`. While this assumption holds
for `HTMLInputElement` that has a shadow DOM with a text node, an empty
`contenteditable` might not have any children. With this change,
`handle_keydown()` creates a new text node if the cursor position's
node is not a text node.
Fixes a crash that occurs when inputting into an empty contenteditable
element (`EditEventHandler::handle_delete()` assumes the cursor
position's node is always `DOM::Text`, which is not the case for an
empty `contenteditable`).
With this commit, we are finally running animations off of the web
animations spec! A lot of the work StyleComputer is doing is now done
elsewhere. For example, fill-forward animations are handled by
Animation::is_relevant() returning true in the after phase, meaning the
"active_state_if_fill_forward" map is no longer needed.
For `:#xx` in names, we now also handle lower-case hex digits.
The spec is silent on the case of these hex digits.
Our previous check (isxdigit(), and now is_ascii_hex_digit()) lets
through lower-case hex digits, so it seems better to handle them
rather than computing e.g. `'a' - 'A' + 10` (== 42 -- off by 32!).
I don't know if this has any visible effect on any files, but it's
more correct, and less code, and the code looks more like the code
in Filter::decode_ascii_hex().
When compiling code like this:
x = { foo: x }
We don't want to put a new JS::Object in `x` until *after* we've
evaluated `x` for the `foo` field.
This fixes an issue when loading https://puter.com/ :^)
`EventHandler::handle_keyup()` and `EventHandler::handle_keydown()`
return true if the event has been handled and false otherwise. This is
the opposite behavior to `EventHandler::fire_keyboard_event()`.
This change inverts the return value from `fire_keyboard_event` in
these methods, allowing shortcut keys to be propagated to the Serenity
Browser UI as expected.
Since it's possible to have the actual recently opened files <
max_recently_open_files(), which causes us to crash when we try to
access new_recent_files_list where index >= the list's size.
Ideal for applications such as PartitionEditor. Previously an error
about how it needs to run as root was displayed which differed from
the behaviour when clicking from the system menus.
Use the new AppFile::spawn_with_escalation to perform the escalation
The old implementation of PassMode has only been tested with a single
image, and let's say that it didn't survive long in the wild. A few
cases were not considered:
- We only supported VerticalMode right after PassMode.
- It can happen that token need to be used but not consumed from the
reference line.
With that fix, we are able to decode every single PDF file from the
1000-file zip "0000" (except 0000871.pdf, which uses byte alignment).
This is massive progress compared to the hundred of errors that we were
previously receiving.
This works very similarly to MarkedVector<T>, but instead of expecting
T to be Value or a GC-allocated pointer type, T can be anything.
Every pointer-sized value in the vector's storage will be checked during
conservative root scanning.
In other words, this allows you to put something like this in a
ConservativeVector<Foo> and it will be protected from GC:
struct Foo {
i64 number;
Value some_value;
GCPtr<Object> some_object;
};
Transforms are applied to both clip rectangle and position, so we need
to remove the transform from clip rectangle before checking if position
falls within the clip rectangle.
In this change, the removal of transform is moved into
`Paintable::clip_rect()` that is shared between hit-testing and
painting.
This change fixes hit-testing in Discord's multifactor authentication
form.
If the layout has been recalculated and the sizes of scrollable
overflow rectangles could have changed, we need to ensure that scroll
offsets remain within the valid range.
By moving scroll offset clamp from `PaintableBox::scroll_by()` to
`PaintableBox::set_scroll_offset()`, we ensure that updates from
`Element::set_scroll_top()` and `Element::set_scroll_left()` are
constrained to a valid range.
Both type 1 and type 2 spec tell us to do this.
I haven't observed a difference from this, but I noticed it in the
spec while I was touching this code. Probably good to do what the
spec tells us to do.
With this, a character can be defined that uses two existing glyphs.
This is useful for umlauts and the like, which then just need to
reference e.g. the glyphs named "a" and "dieresis" and provide a
translation.
Makes umlauts appear on some PDFs using CFF type2 data in Type 1
fonts.
This allows ports to access the OpenGL headers using `#include
<GL/gl.h>` and find the shared library at `/usr/lib/libGL.so` or
`/usr/lib/libGL.so.1`, removing the need for explicit include paths or
changed library names.
Before, TEST_MAIN used to return the return value of TestSuite::main()
function (which returns the number of test cases that did not pass, so
it can be >=256) directly.
The run-tests utility determines the success / failure of a test suite
binary by examining its (or i.e. TEST_MAIN's) exit status.
But as exit status values are supposed to be between 0 and 255, values
>=256 will get wrapped around (modulo 256), converting a return value of
256 to 0.
So, in a rare case where exactly 256 test cases are failing in your test
suite, run-tests utility will display that the test suite passed without
any failures.
Now, TEST_MAIN just returns 0 if all of the test cases pass and returns
1 otherwise.
Ceiling width or height of a chrome viewport (this function is only used
when a chrome notifies LibWeb about a new viewport size) is never
correct. If we do that, PageClient::page_did_layout will set content
size to be 1 larger than an actual physical width or height respectively
(it always ceils) and thus a spurious scrollbar will appear.
This prevents occasional scrollbar flickering in Ladybird/Qt on Wayland
with fractional scaling enabled on compositors supporting
wp-fractional-scale-v1.
