ICU 72 began using non-ASCII spaces in some formatted date-time strings.
Every major browser has found that this introduced major breakage in web
compatibility, as many sites and tools expect ASCII spaces. This patch
removes these non-ASCII spaces in the same manner as the major engines.
Such behavior is also tested by WPT.
This removes the --enable-callgrind-profiling flag, and replaces it with
a --profile-process=<process-name> flag. For example:
ladybird --profile-process=WebContent
ladybird --profile-process=RequestServer
This allows profiling any helper process with callgrind.
This removes the --debug-web-content flag, and replaces it with a
--debug-process=<process-name> flag. For example:
ladybird --debug-process=WebContent
ladybird --debug-process=RequestServer
This allows attaching gdb to any helper process.
Overflow clipping is currently implemented as:
1. Create clip frame for each box with hidden overflow
2. Calculate clip rect for each clip frame by intersecting padding boxes
of all boxes with hidden overflow in containing block chain
3. Assign enclosing clip frame (closest clip frame in containing block
chain) to each PaintableBox
4. Apply clip rect of enclosing clip frame in Paintable::before_paint()
It breaks when any CSS transform other than simple translation is lying
between box with hidden overflow and a clipped box, because clip
rectangle will be applied when transform has already changed.
The fix is implemented by relying on the following rule:
"For elements whose layout is governed by the CSS box model, any value
other than none for the transform also causes the element to establish
a containing block for all descendants."
It means everything nested into a stacking context with CSS transform
can't escape its clip, so it's safe to apply its clip for all children.
Adds missing clip of border-radius for clip frame. While we have already
accounted for the border-radius of containing blocks, the box itself was
not being clipped.
Remove `for_each_section_of_type` in favor of making the module's
sections defined as distinct fields. This means it is no longer possible
to have two of the same section (which is invalid in WebAssembly, for
anything other than custom sections).
Now that the implementation is in FormAssociatedElement, the
implementation in HTMLInputElement is effectively just a passthrough,
with some minor differences to handle small behavioural quirks between
the two (such as the difference in nullability of types).
The user is not required to keep the object alive, this commit makes it
so the lifetime of these functions is extended to match the Wasm module
it is imported into.
Fixes the crash in #907.
Currently, if we want to add a new e.g. WebContent command line option,
we have to add it to all of Qt, AppKit, and headless-browser. (Or worse,
we only add it to one of these, and we have feature disparity).
To prevent this, this moves command line flags to WebView::Application.
The flags are assigned to ChromeOptions and WebContentOptions structs.
Each chrome can still add its platform-specific options; for example,
the Qt chrome has a flag to enable Qt networking.
There should be no behavior change here, other than that AppKit will now
support command line flags that were previously only supported by Qt.
We don't want to set the intrinsic Console object's client to non-top-
level clients, created for e.g. subframes. We also want to make sure the
Console client is updated if the top-level document has changed.
We explicitly stopped visting the map of documents to console clients in
commit 44659f2f2a to avoid keeping the
document alive. However, if nothing else visits the console clients, we
may set the top-level console client to a client that has been garbage
collected.
So instead of storing this map, just store the console client on the
document itself. This will allow the document to visit its client.
Moves paint_table_borders() call into PaintableBox::paint() to make
scroll offset and clip rectangle of enclosing scrollable be applied
in ::before_paint().
Previously, pseudo-elements had their style computed while the layout
tree was being built. Instead, do so inside Element::recompute_style(),
using the same invalidation mechanism that the element itself uses.
This also has the effect of invalidating the layout much less often.
Pseudo-elements' style is only computed while building the layout tree.
This meant that previously, they would not have their style recomputed
in some cases. (Such as when :hover is applied to an ancestor.)
Now, when recomputing an element's style, we also return a full
invalidation if one or more pseudo-elements would exist either before or
after style recomputation.
This heuristic produces some false positives, but no false negatives.
Because pseudo-elements' style is computed during layout building, any
computation done here is then thrown away. So this approach minimises
the amount of wasted style computation. Plus it's simple, until we have
data on what approach would be faster.
This fixes the Acid2 nose becoming blue when the .nose div is hovered.
Contrary to LibGfx, where corner clipping was implemented by sampling
and blitting pixels under corners into a temporary bitmap, Skia allows
us to simply apply a mask. As a result, we no longer need the
BlitCornerClipping command, which has become a no-op.
- SampleUnderCorners is renamed to AddRoundedRectClip
- The optimization that skipped unnecessary blit and sample commands has
been removed. However, this should not result in a performance
regression because Skia seems to perform mask rasterization lazily.
In the HTML parser spec, there are 2 instances of the following text:
add the attribute and its corresponding value to that element
The "add the attribute" text does not have a corresponding spec link to
actually specify what to do. We currently use `set_attribute`, which can
throw an exception if the attribute name contains an invalid character
(such as '<'). Instead, switch to `append_attribute`, which allows such
attribute names. This behavior matches Firefox.
Note we cannot yet make the unclosed-html-element.html test match the
expectations of the unclosed-body-element.html due to another bug that
would prevent checking if the expected element has the right attribute.
That will be fixed in an upcoming commit.
