Though table wrappers are anonymous block containers (because
TableWrapper is inherited from BlockContainer) with no lines they
should not be skipped in block auto height calculation.
This is a first pass at implementing CRC2D.createPattern() and the
associated CanvasPattern object. This implementation only works for a
few of the required image sources [like CRC2D.drawImage()], and does
not yet support transforms. Other than that it supports everything
else (which is mainly the various repeat modes).
The shadowRoot property getter that will be added in subsequent commits
has an additional check that checks whether the shadow root is opened.
I didn't update the function logic to match with the IDL interface,
because it's very likely we don't want that check in the existing code,
so that for example closed shadow root elements can still be updated.
This adds support for WebSocket subprotocols to WebSocket DOM
objects, with some necessary plumbing to LibWebSocket and its
clients.
See the associated pull request for how this was tested.
There is currently a memory leak with these file request objects due to
the callback on_file_request_finish referencing itself in its capture
list. This object does not need to be reference counted or allocated on
the heap. It is only ever stored in a HashMap until a response is
received from the browser, and it is not shared.
`Stream` will be qualified as `AK::Stream` until we remove the
`Core::Stream` namespace. `IODevice` now reuses the `SeekMode` that is
defined by `SeekableStream`, since defining its own would require us to
qualify it with `AK::SeekMode` everywhere.
ARIA roles no longer use DeprecatedFlyString, replace them with the
forwarding header, and StringView.h in one case, for other things from
AK used in those headers.
ARIA has its own spec and is not part of the DOM spec, which is what the
Web::DOM namespace is for (https://www.w3.org/TR/wai-aria-1.2/).
This allows us to stay closer to the spec with function names and don't
have to add the word "ARIA" to identifiers constantly - the namespace
now provides that clarity.
Note that as of this commit, there aren't any such throwers, and the
call site in Heap::allocate will drop exceptions on the floor. This
commit only serves to change the declaration of the overrides, make sure
they return an empty value, and to propagate OOM errors frm their base
initialize invocations.
The goal here is to allow Cell::initialize to return a ThrowCompletion,
to handle OOM for example. Cell.h will then need to include Completion.h
which must include Value.h. This currently can't happen because Value.h
includes BigInt.h, which in turn includes Cell.h. So we would have an
include cycle.
This removes BigInt.h from Value.h, as it is forward-declarable (it is
only referred to with a reference or pointer). Then the Value overload
for Cell::Visitor::visit is moved to Cell.h, and missing BigInt.h
includes as peppered as needed.
This replaces the FlyStrings for ARIA roles that were constructed in
a [[gnu::constructor]] with a single enum. I came across this as the
DOM inspector was crashing due to a null FlyString for an ARIA role.
After fixing that, I was confused as to why these roles were not an
enum. Looking at the spec there's a fixed list of roles and switching
from references to static strings to an enum was pretty much an
exercise in find and replace :).
No functional changes (outside of fixing the mentioned crash).
Having an alias function that only wraps another one is silly, and
keeping the more obvious name should flush out more uses of deprecated
strings.
No behavior change.
We were incorrectly using the inner main size of the flex container
instead of the avilable space in some parts of the remaining space
calculation. This meant that the algorithm only worked correctly
for definite available space in the main axis.
If we've already established the used width for a flex item, we need
to take it into account when calculating the min-content and max-content
heights for that item.
We were already doing this when calculating cross sizes. This patch adds
the same consideration for main sizes.
Previously block auto height calculation was changed to skip boxes with
collapsed margins and then condition to skip anonymous boxes with no
lines was also removed in 6c5ba10bb0 to
avoid skipping anonymous wrappers of tables.
Skipping boxes with collapsed margins (currently it's check that
height is 0) is wrong because it makes empty boxes with clearance to
be skipped which is not correct while anonymous boxes with no lines
should be skipped and it's no longer causes problems with tables
(fixed in 87f0e835eb)
Commit 7dc0edcb86 was supposed to prevent
floats from being placed higher than preceding boxes but the change
turned out to be completely wrong and caused regressions because:
1. Call to `clear()` in `layout_block_level_children` would reset
floating boxes only after layout of box with _not_ inline children
although the same should happen after layout of IFC.
2. `clear()` causes offset y of floats to be reset but it also clears
all currently enocuntered floating boxes which means the next box
that has actual clearance will get wrong y position.
There is a problem with current approach where overflow clip rectange is
calculated by aggregating intersection of absolute padding boxes of
boxes in containing block chain that resulting rectangle doesn't
respect transform properties.
To solve this problem `PaintableBox` is changed to store clip rectangle
saved from painter because it does respect transform properties of all
previously applied clip rectangles.
Here .to_string() was being called, which gives an ErrorOr<String>,
then .value() was called on that without any checks. Cases like this
should at least be .release_value_but_fixme_should_propagate_errors()
which makes it clear the error is ignored, but here it's easy to
propagate.
