Areas are disassembled into boundary lines on `build_grid_areas()` step,
so we can always use them to find grid item's position during placement.
This way we support both ways to define area: `grid-template-areas` and
implicitly using `-start` and `-end` boundary line names.
Before this change, we were passing them as Gfx::ShareableBitmap. The
problem is that shareable bitmaps keep their underlying file descriptor
open, so that they can be shared again with someone else.
When a Gfx::Bitmap is decoded from an IPC message, the file descriptor
is closed and recovered immediately.
This fixes an issue where we'd accumulate one file descriptor for every
image decoded. This eventually led to descriptor starvation after enough
images were loaded and still referenced at the same time.
- `-fstack-protection-strong` enables stack canaries for functions where
addresses of local variables are taken or arrays/structures
containing arrays are allocated on the stack.
- `-fstrict-flex-arrays=2` causes the compiler to only treat arrays with
unknown bounds (`[]`) or zero-length-arrays (`[0]`) as *flexible array
members*, allowing the sanitizers to emit bounds checks for structs
with proper arrays as their last member.
More rigorous options (such as AArch64 pointer authentication, Control
Flow Integrity, _FORTIFY_SOURCE) should be investigated in the future,
however this is a good baseline.
If no header includes the prototype of a function, then it cannot be
used from outside the translation unit it was defined in. In that case,
it should be marked as `static`, in order to avoid possible ODR
problems, unnecessary exported symbols, and allow the compiler to better
optimize those.
If this warning triggers in a function defined in a header, `inline`
needs to be added, otherwise if the header is included in more than one
TU, it will fail to link with a duplicate definition error.
The reason this diff got so big is that Lagom-only code wasn't built
with this flag even in Serenity times.
These used to be enabled in `serenity_compile_options.cmake` for
Serenity builds and were removed in 9b05fb98. This is a slightly more
conservative subset of those, with ones that are enabled by default
omitted.
This should prevent our code quality regressing in the long run.
This matches libwebp (see ZeroFillCanvas() call in
libwebp/src/demux/anim_decode.c:355 and ZeroFillFrameRect() call
in line 435, but in WebPAnimDecoderGetNext()) and makes files
written e.g. by asesprite look correct -- even though the old
behavior is also spec-compliant and arguably makes more sense.
Now nothing looks at the background color stored in the file.
See PR for an example image where it makes a visible difference.

- Change min track sizing function to be "auto" when flex size is
specified.
- Never check if min track sizing funciton is flexible, because only
max is allowed to be flexible.
- Address FIXME in automatic_minimum_size to avoid regressions after
making two fixes mentioned above.
The JS::Error types all store their exception messages as a String. So
by using ByteString, we hit the StringView constructor, and end up
allocating the same string twice.
Otherwise we'd hit a VERIFY in AK::SIMD::shuffle() when that operand
contains an out-of-range value, the spec tests indicate that a swizzle
with an out-of-range index should return 0.

This necessitates marking bit_cast as ALWAYS_INLINE since emitting it as
a function call there will create an unnecessary potential SSE
registers -> plain registers/memory round-trip.
The change causes Tests/LibWeb/WPT/run.sh to run an arbitrary subset of
tests you give it as arguments. If you don’t specify any arguments, it
has the same behavior as it does without this patch: It just runs an
explicit subset of test names hardcoded into the script.
Otherwise without this change, Tests/LibWeb/WPT/run.sh doesn’t have the
ability to run any tests other than the explicit subset of test names
hardcoded into the script
Enforce the use of the CPU backend in test mode to ensure that ref-tests
produce consistent results across different computers, as this
consistency cannot be achieved with the GPU backend.
We already have a FlyString of its value from parsing, and most users
also want a FlyString from it, so let's use that instead of converting
backwards and forwards.
The two users that did want a String are:
- Quotes, which make sense as FlyString instead, so I've converted that.
- Animation names, which should probably be FlyString too, but the code
currently also allows for other kinds of StyleValue, and I don't want
to dive into this right now to figure out if that's needed or not.
Each item in clip_paths represents a glyph run, and applying them as a
clip in intersection mode one by one results in an empty clip. Instead,
now all clip paths are joined and applied as a clip together.
This change fixes rendering of "background-clip: text" when an element
has more than one glyph run.
Fixed ref-test: Tests/LibWeb/Ref/css-background-clip-text.html
