The seek table must locate the first MP3 frame in the file, so it makes
sense to locate the samples for the sample table first, then that
information to seek to the first frame.
Previously, we would just start from byte 0 and check individual bytes
of the file until we find two bytes starting with `FF F`, and then
assume that that was the MP3 frame sync code. However, some ID3v2 tags
do not have to be what is referred to as "unsynchronized", meaning that
they can contain that `FF F` sequence and cause our decoder to think it
has found a frame.
To avoid this happening, we can read a minimal amount of the ID3 header
to determine how many bytes to skip before attempting to find the MP3
frames.
This allows the recent podcast with Andreas to play here:

Seek points were being created after adding to the sample count in
`build_seek_table()`, meaning that they would be offset forward by
`MP3::frame_size` samples.
This also allows us to remove the hardcoded sample 0 seek point that
was previously added, since a seek point at sample 0 will now be added
by the loop.
This is intended to annotate conversions from unknown floating-point
values to CSSPixels, and make it more obvious the fp value will be
rounded to the nearest fixed-point value.
In general it is not safe to convert any arbitrary floating-point value
to CSSPixels. CSSPixels has a resolution of 0.015625, which for small
values (e.g. scale factors between 0 and 1), can produce bad results
if converted to CSSPixels then scaled back up. In the worst case values
can underflow to zero and produce incorrect results.
Move the methods to set the native/user style sheets to the base
ViewImplementation class. We must also generate the native style sheet
explicitly for now, as LibWebView on Lagom isn't able to include the
main LibWebView CMakeLists.txt file yet.
This means StyleComputer::resolve_unresolved_style_value() always
returns a value, so we can change its return type.
However, it does still return an UnresolvedStyleValue sometimes, so we
can't remove those checks from the user code.
These options are not relevant and are actually meaningless on pure TTY
devices, as they are meant to be effective only for the VirtualConsole
devices.
This also removes the virtual marking from two methods because they're
no longer declared in the TTY class as well.
There is a bug in the "search by typing" feature of
AbstractView, where the highlighted text shown in items' title won't
match the search query if the search query contains whitespace.
This commit fixes that bug.
The bug is caused by a bad assumption made in
AbstractView::draw_item_text about the Painter::draw_text API.
Specifically that the function passed to it will be called for each
code point of the string instead of for each drawable glyph.
This is fixed by not relying on looking at the length of the highlight
string, but instead looking at its content.
This function returns the first element which matches both the filter
for the LiveNodeList collection itself, and a further filter that is
supplied as an argument to this function.
- Ambiguous `raw_value()` method is replaced with `line_number()` and
`span()`.
- `line_name()` that before returned either line name or area name is
replaced with `line_name()` and `area_name()`.
- `Position` type is replaced with `Line` and `Area` type so we don't
have to guess while doing layout.
Affected test expectations:
- `template-lines-and-areas` - improvement over what we had before.
- `named-tracks` - rebaseline a giant test. will have to split it into
smaller tests in the future.
The invariants for these property getters are supposed to be checked by
the has_entries_and_events_disabled AO, but we don't have all the
plumbing hooked up between Navigables and Navigation yet.
Add a test to make sure that these methods don't assert when calling
them on a fresh page.
The spec allows for these either to be based on the OS, or to be defined
by the browser. Looking at the other browser engines, there's a mix of
the two options. Since we've had issues with using OS colors as
defaults, let's use hard-coded colors for now. Some of these are based
on the definitions in
https://html.spec.whatwg.org/multipage/rendering.html
Reuse the check from IdentifierStyleValue in the CSS Parser, instead of
duplicating it. This might not be the ideal place to put it, but it
works for now.
The resolution is simply 1dppx * device pixel ratio.
This makes high resolution images show up on https://apple.com/
when running on a high-DPI display. :^)
The implementation is incomplete, because our Navigable::navigate
implementation is missing the navigationAPIState parameter. We also
don't have Navigables hooked up completely enough to guarantee that a
fully active document that is not being unloaded always has a Navigable.
This is used by both Navigable and Navigation, so let's put it in
Navigable. Also add a missing AK/String include to make clangd happier
with the Navigable file.
Every property in an IDL dictionary is implied to be optional, unless it
is marked as required. If a dictionary is passed to a method with
optional, but it has at least one required or defaulted member, the
bindings will skip the optionality of the parameter and always pass a
struct with the required parameters filled in.
Without setting the --resources flag, headless-browser defaults to /res
for all resources it tries to find, including the theme. It will not
find this path on Lagom, so our attempt to load the default theme does
not accomplish anything.
This patch introduces a new function "Layer::editin_mask_bounding_rect"
that is used within the LevelsDialog, Luminosity and Colormasking to
process only the area where a mask was applied. Therefore we can
greatly reduce the amount of processed pixels if only a small portion
of the image was masked.
With this patch the histogram and vectorscope data for the image is
only computed when the widgets are visible to the user and therefore
saves some processing time when this information is not required
to be computed.
These syscalls are not necessary on their own, and they give the false
impression that a caller could set or get the thread name of any process
in the system, which is not true.
Therefore, move the functionality of these syscalls to be options in the
prctl syscall, which makes it abundantly clear that these operations
could only occur from a running thread in a process that sees other
threads in that process only.
This new Kernel StdLib function will be used to copy contents of a
FixedStringBuffer with a null character to a user process.
The first user of this new function is the prctl option of
PR_GET_PROCESS_NAME which would copy a process name including a null
character to a user provided buffer.
When doing PR_{SET,GET}_PROCESS_NAME, it's not expected to pass a signed
integer for the buffer size (in arg2). Therefore, cast it immediately to
a size_t integer type, and let the FixedStringBuffer StdLib memory copy
functions in such cases to worry about possible overflows.
Note that we don't load the local font as specified, but at least we no
longer reject such src properties in the CSS parser.
This makes the custom fonts used on http://apple.com/ actually load. :^)
