The expression evaluator is dead code that does nothing but crash on
all paths, as no opcodes are implemented.
Stubbing out the LocListX form fixes a crash while reading DWARF 5
debug data that contains location lists. These are just a new way
to store location expressions, and since we never implemented
expressions, we can just ignore these too.
As far as I can tell this is enough for DWARF 5 to work for us (since
we mainly just use the line tables).

Unwind contexts now remember the lexical and variable environments in
effect when they were created. If an exception is caught, we revert
to those environments in the running execution context.
|
|
For `try` statements with a `catch` clause, we were generating *two*
"next" blocks. This meant that not throwing an exception would cause
execution to stop.
Fix this by using the "next" block pointer for the try "entry" and
"handler" blocks.

This change brings calculate_minimum_contribution() for grid items and
supporting functions.
|
|
This fixes an issue where object environments (from `with` statement)
were bypassed by statements like `var x = 1` (for objects with an `x`
property).
Fixes 25 tests in test262. :^)

This will be used by performance.measure to read the value of a given
entry in the NavigationTiming interface.

|
This implements the substeps which concern HTMLMediaElement parents.
|
|
Rather than setting the src attribute on the HTMLMediaElement, websites
may append a list of HTMLSourceElement nodes to the media element. There
is a series of "try the next source" steps to attempt to fetch/load each
source until we find one that works.

There's no need for this to require a DeprecatedString - the method it
wraps around already only expects a StringView. This allows passing a
String instance without any conversion.

And only paint GlyphMapWidget's frame if disabled
|
|
|
|
FontEditor will need to clear references to its mutable font in
the future while CharacterMap has no use for the highlights clone,
so let's convert GlyphMapWidget's set_font wrapper into a separate
initialize function for the editor and stop hiding the base function
for others. Setting font null in either ultimately points the map to
the system's default font.
|
|
This will let us neatly ensure capacities, do unchecked appends, and
iterate by size() on FontEditor's models.
|
|
|
|
Fixes seek actions not activating by keyboard shortcut when
GlyphMapWidget has focus.

automatic_content_width() should return grid container width that is
supposed to be set by determine_intrinsic_size_of_grid_container().
|
|
When a width/height constraint is applied to GFC it should set its own
width/height to the sum of track sizes according to the spec.
Changes in layout tests are improvement over what we had before.
|
|
This solves the issue when track with "fixed" min sizing function were
treated like "auto" during sizing.
|
|
|
|
We achieve this by adding a new Layout::ImageProvider class and having
both HTMLImageElement and HTMLObjectElement inherit from it.
The HTML spec is vague on how object image loading should work, which
is why this first pass is focusing on image elements.
|
|
This first pass is enough to get us:
- Image loading via fetch
- Source selection via srcset and sizes attributes
|
|
Also comes with a little extra CSS parser helper for parsing "sizes"
attributes in images.
|
|
|
|
This patch adds HTML::ImageRequest and HTML::DecodedImageData.
The latter had to use a different name than "ImageData", as there is
already an IDL-exposed ImageData class in HTML.

Found while playing Fixme-Roulette.

It looks like this migration it taking a while, so let's make sure noone
accidentally introduces new usages of this currently-unused API.

This makes hovering around on GitHub fast again, as it no longer
believes that the grid-template-areas property keeps changing
when it didn't :^)
Also made to_string() work for calc() values as well, since I stumbled
upon that while debugging this.
|
|
|
|
This change brings more spec compliant implementation of functions to
calculate min/max contributions of grid items in containing block size.
|
|
This results in a new OOM prevention. Hooray!
|
|
This prevents callers from accidentally discarding the result of
initialize(), which was the root cause of this OSS Fuzz bug:

Note that this unfortunately requires the same workaround as <link>
elements to handle CORS cross-origin responses.
|
|
The UTF-8 decoder will currently crash if it is provided invalid UTF-8
input. Instead, change its behavior to match that of all other decoders
to replace invalid code points with U+FFFD. This is required by the web.
|
|
This will make it more convenient in places where the Variant would need
to be re-typed outside of this class.
|
|
The completion callback currently only accepts a JavaScriptModuleScript.
The same callback will need to be used for ClassicScript scripts as well
so allow the callback to accept any Script type. The single existing
outside caller already stores the result as a Script.

If this value somehow becomes nan/inf the painter will keep splitting
the path till the process OOMs, a simple crash would be preferable.
|
|
If just .to_px() is used the height can end up as the float `inf` or
`nan`. This caused an OOM when loading Polygon as this `inf` would
become a `nan` and propagate to the SVG painting, which then attempts
to draw a path with nan control points, which would make the
Gfx::Painter infinitely split the path till it OOM'd.

Previously, the width and height of grid items were set to match the
size of the grid area they belonged to. With this change, if a grid
item has preferred width or height specified to not "auto" value it
will be resolved using grid area as containing block and used instead.
|
|
Adds missing part of grid size parsing function to handle calc().
|
|
Using LengthPercentage instead of Length and Percentage separately
is going to allow GridSize to store calc() values. It also allows
to simplify some parts of layout code.
|
|
We were resolving percentage values against the containing block size in
the wrong axis.
|
|
While it's possible to getComputedStyle() on an unconnected element,
the resulting object is not supposed to have any values, since we can't
resolve style without a document root anyway.
This fixes a crash on https://bandcamp.com
