The SVGContext is a leftover from when SVG properties were more ad-hoc.
All properties are now (for better or worse) treated as CSS properties
(or handled elsewhere). This makes the SVGContext's fill/stroke
inheritance handling unnecessary.
This is a preparation before we can create a usable mechanism to use
filesystem-specific mount flags.
To keep some compatibility with userland code, LibC and LibCore mount
functions are kept being usable, but now instead of doing an "atomic"
syscall, they do multiple syscalls to perform the complete procedure of
mounting a filesystem.
The FileBackedFileSystem IntrusiveList in the VFS code is now changed to
be protected by a Mutex, because when we mount a new filesystem, we need
to check if a filesystem is already created for a given source_fd so we
do a scan for that OpenFileDescription in that list. If we fail to find
an already-created filesystem we create a new one and register it in the
list if we successfully mounted it. We use a Mutex because we might need
to initiate disk access during the filesystem creation, which will take
other mutexes in other parts of the kernel, therefore making it not
possible to take a spinlock while doing this.
This change was a long time in the making ever since we obtained sample
rate awareness in the system. Now, each client has its own sample rate,
accessible via new IPC APIs, and the device sample rate is only
accessible via the management interface. AudioServer takes care of
resampling client streams into the device sample rate. Therefore, the
main improvement introduced with this commit is full responsiveness to
sample rate changes; all open audio programs will continue to play at
correct speed with the audio resampled to the new device rate.
The immediate benefits are manifold:
- Gets rid of the legacy hardware sample rate IPC message in the
non-managing client
- Removes duplicate resampling and sample index rescaling code
everywhere
- Avoids potential sample index scaling bugs in SoundPlayer (which have
happened many times before) and fixes a sample index scaling bug in
aplay
- Removes several FIXMEs
- Reduces amount of sample copying in all applications (especially
Piano, where this is critical), improving performance
- Reduces number of resampling users, making future API changes (which
will need to happen for correct resampling to be implemented) easier
I also threw in a simple race condition fix for Piano's audio player
loop.
Assertion fails if the point is outside of the rect. This was introduced
in introduced in #18970 and causes serenity to crash when changing to 2x
resolution for a monitor, if the cursor after resizing is outside of
the new screen.
Added test to reproduce.
This turns all errors into either "OOM" or a proper shell error (if
propagation is impossible or meaningless).
Fixes `echo -en '\xfe\x4a' | $SHELL` crashing.
Before this change, we only blurred the shadows which would've been
generated without blur. This meant that we didn't generate a shadow when
the offset was zero, even with blur. However, other browsers generate a
shadow when blur is set.
Instead, always generate a rectangular contour of sufficient thickness,
blur it if needed and blit it into the right position at the very end.
Thanks to the blur radius, we'll have a shadow even when the offset is
zero.
This is a similar strategy to what v8 does. Use the ASAN API function
__asan_addr_is_in_fake_stack to check any fake stack frames associated
with each stack address we scan. This fully allows running test-js -g
with the option detect_stack_use_after_return turned on.
Instead of checking the address of a temporary, grab the address of the
current frame pointer to determine how much memory is left on the stack.
This better communicates to the compiler what we're trying to do, and
resolves some crashes with ASAN in test-js while the option
detect_stack_use_after_return is turned on.
The valid range for temporal values (`nsMinInstant`/`nsMaxInstant`)
means performing nanosecond-valued integers could lead to an overflow.
NB: Only the `roundingMode: "day"` case was affected, as all others were
already performing the division on floating-point `fractional_second`
values. I'm adding `.0` suffixes everywhere to make this fact clearer.
This adds a few local tests as well, as those are tested with sanitizers
enabled by default, unlike test262.
Otherwise, reading will sometimes fail on the Raspberry Pi.
This is mostly a hack, the spec has some info about how the correct
divisor should be calculated and how we can recover from timeouts.
Namely, we previously forgot to configure the SD Host Controller for
4-bit mode after issuing ACMD6, which caused data transfers to fail on
bare metal.
`parse_a_calc_function_node()` only detects math functions, but
regularly encounters unrelated functions like `rgba()`. Since we now
support all the math functions, this message is just misleading spam.
In the merging of an extremely large navigables PR, a task queue source
was added after the unique task source start value that was supposed to
remain last in the enum.
This was missed in 02b74e5a70
We need to disable consteval in AK::String as well as AK::StringView,
and we need to disable it when building both the tools build and the
fuzzer build.
Computing the table width algorithm bifurcates based on whether
table-root width is auto. We only adjust the used table width based on
cell percentage widths on the auto branch, thus the same check is needed
when we initialize cell widths.
This makes them trivially copyable, which is an assumption multiple
optimizations use when rebuilding the instruction stream.
This fixes most optimized crashes in the test262 suite.

After this refactoring, we now correctly handle non-function /
non-undefined objects being passed multiple times: instead of skipping
assignment to promiseCapability altogether and failing with a
NotAFunction error in the end; on the second time the executor closure
is called, we return GetCapabilitiesExecutorCalledMultipleTimes.
This fixes the 7 `capability-executor-called-twice.js` test262 tests.
These recursive templates have a measurable impact on the compile speed
of Variant-heavy code like LibWeb. Using these builtins leads to a 2.5%
speedup for the measured compilation units.
