The old FIXME asserting that Core::AnonymousBuffer cannot be invalid
or zero-sized is no longer accurate. Add a default constructor for
Audio::Buffer that has all invalid state instead of going to the OS to
allocate a 1 sample buffer for the "no more samples" states in the WAV
and FLAC plugins.
While quantifying assertions is very much meaningless, the specification
allows them with annex B's extended grammar for browsers, so read and
apply the quantifiers.
Fixes#12373.
Although it is not said that some of the elements need to be italic,
*most* browsers mark them as such to distinguish them from the normal
text, so let's do that too!
The entry we get from the active formatting elements list during the
Rewind step of "reconstruct the active formatting elements" can be a
marker. Previously we assumed it was not a marker, which can trigger
an assertion failure with certain malformed HTML.
If the entry in this step is a marker, the spec simply ignores it.
This is step 6 of the algorithm.
This also makes the index unsigned, as this algorithm is a no-op if
the list is empty.
Additionally, this also adds spec comments to this algorithm.
Fixes#12668.
This patch adds a default padding around the contents of text <input>
elements. It adds these defaults to the existing style attribute in
'HTMLInputElement::create_shadow_tree_if_needed()'.
Use a default padding for text <input> elements:
- padding-top and padding-bottom: 1px
- padding-left and padding-right: 2px
These values seems to align with what other browsers do.
This also adds a variant of {add,remove}_event_listener called
{add,remove}_event_listener_with_options.
This is used internally to perform {add,remove}_event_listener with a
default constructed options struct. It was done like this because
default constructing the Variant with the options struct requires the
struct defintions to be present, which requires us to include
AbortSignal.h, which would cause a circular include as AbortSignal.h
includes EventTarget.h.
Some grayscale JPG images might have the horizontal and vertical sample
factor set to 2. However, the macroblocks in these images are not
interleaved as they would be in color images.
Previously it would accept any DOMString, as we didn't support enums at
the time. Now it will only accept what's specified in the
DOMParserSupportedType enum.
This also adds spec comments to DOMParser::parse_from_string.
We were previously manually initializing them instead of just calling
GlobalObject::initialize_constructor, which aside from duplicating code
also meant we didn't set the required name property.
Normally we don't layout position:absolute elements until after the
parent formatting context has assigned dimensions to the current
formatting context's root box.
However, some of our parent contexts (especially FFC) don't do this
reliably, which makes position:absolute children have 0x0 dimensions.
Hack this for now by making ~BFC() pretend that the parent assigned
dimensions if it hadn't done it already.
This returns a String with this format:
- LayoutNodeClassName<TAG_NAME>#id.class1.class2.class3
I've rewritten this function 10+ times at this point, so I'm just gonna
add it to the repository for future debugging needs. :^)
After style computation, every StyleProperties has a value for every
PropertyID. Given this, it's simpler, faster and less memory-heavy to
use an Array instead of a HashMap. :^)
This adds a small tooltip in the browser showing the size of the
element that currently selected in the inspector view. This allows
for easier debugging since you dont have to dump the layout tree :^).
Previously, we stored a RefPtr to the HackStudioWidget in the
global scope.
This led to a destruction-order related use-after-free bug, where the
global HackStudioWidget instance destructed after the static-local
GUI::Clipboard instance.
When HackStudioWidget destructs it attempts to use the global Clipboard
instance, which had already been freed.
This caused the Hack Studio process to spin endlessly on exit because
it attempted to access the HashTable of the freed Clipboard object.
We now store a global WeakPtr to the HackStudioWidget instead, and
limit the lifetime of the object to the main function scope.
Arguments larger than 32bit need to be passed as a pointer on a 32bit
architectures. sys$profiling_enable has u64 event_mask argument,
which means that it needs to be passed as an pointer. Previously upper
32bits were filled by garbage.
