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
Implement for CreatePerIterationEnvironment for 'for' loops per the Ecma
Standard. This ensures each iteration of a 'for' loop has its own
lexical environment so that variables declared in the loop are scoped to
the current iteration.
This change updates the Meta/check-debug-flags.sh script to avoid an
apparent Bach 3.2 parser bug. Specifically, it takes a comment and some
code of a process substitution and moves it into a separate function.
Otherwise, without this change, trying to run the check-debug-flags.sh
script with Bash 3.2 fails with the following error:
line 39: bad substitution: no closing `)' in <(
...apparently because Bash 3.2 chokes on the comment (and doesn’t choke
if the comment is completely removed).
Relates to https://github.com/LadybirdBrowser/ladybird/issues/283
This change makes all the pre-commit CI scripts runnable under Bash 3.2,
by replacing “mapfile” invocations in them code that first explicitly
creates an array, and then uses a while loop to populate the array.
Otherwise, without this change, the scripts all fail to run under Bash
3.2 — due to lack of support for “mapfile”.
Fixes https://github.com/LadybirdBrowser/ladybird/issues/283
This also drops bash from the list of homebrew dependencies in the build
instructions — because with this change, homebrew bash (v4) is no longer
needed; things will now work with the Apple-provided bash (v3.2)
Couple fixes found by reading the spec:
- Repeating should also happen in negative direction, so the whole
[0, 1] is covered.
- Leftmost and rightmost stops should be clamped to [0, 1] range if
needed, because Skia ignores everything outside of this range.
We currently have 2 base64 coders: one in AK, another in LibWeb for a
"forgiving" implementation. ECMA-262 has an upcoming proposal which will
require a third implementation.
Instead, let's use the base64 implementation that is used by Node.js and
recommended by the upcoming proposal. It handles forgiving decoding as
well.
Our users of AK's implementation should be fine with the forgiving
implementation. The AK impl originally had naive forgiving behavior, but
that was removed solely for performance reasons.
Using http://mattmahoney.net/dc/enwik8.zip (100MB unzipped) as a test,
performance of our old home-grown implementations vs. the simdutf
implementation (on Linux x64):
Encode Decode
AK base64 0.226s 0.169s
LibWeb base64 N/A 1.244s
simdutf 0.161s 0.047s
We no longer have multiple locations including AK (e.g. LibC). So let's
avoid awkwardly defining the AK library across multiple CMake files.
This is to allow more easily adding third-party dependencies to AK in
the future.
When traversing the layout tree to find an appropriate box child to
derive the baseline from. Only the child's margin and offset was being
applied. Now we sum each offset on the recursive call.
