This fixes a few issues I noticed when playing around with radio
buttons. Previously radio buttons would uncheck checkboxes with
the same "name" attribute, uncheck inputs across different forms,
and treated no name attribute as a group.
This now implements the radio button group check from the HTML spec.
In the case where an error is created from an errno, calling
string_literal() will print nothing. Using Error's formatter
instead gives a more descriptive error message.
Previously, the position of the mask used to calculate the new
selection did not match the position of the active layer. The program
would crash when trying to set a mask pixel outside the bounds of the
active layer.
If the font dictionary didn't specify custom glyph widths, we would fall
back to the specified "missing width" (or 0 in most cases!), which meant
that we would draw glyphs on top of each other in a lot of cases, namely
for TrueTypeFonts or standard Type1Fonts with an OpenType fallback.
What we actually want to do in this case is ask the OpenType font for
the correct width.
A limit of 1024 subroutines seemed like a sensible choice, but some
fonts actually do exceed it. We will now only assert that the specified
amount is positive.
Previously, get_inheritable_object would always try to find the object
and throw an error if it couldn't. The spec tells us that some page
attributes, like CropBox, are optional but also inheritable. Others,
like the media box and resources, are technically required by the spec,
but omitted by some documents.
In both cases, we are now able to search for inheritable objects and
find a suitable replacement if there wasn't one.
This makes it easy to compare the performance of Serenity's
deflate implementation to the host system implementation.
On my M1 Max MBP:
% time gunzip -c \
/Users/thakis/Downloads/trace_bug.json.gz > /dev/null
takes between 0.064s and 0.082s.
% time Build/lagom/gunzip -c \
/Users/thakis/Downloads/trace_bug.json.gz > /dev/null
on the other hand takes 4 seconds.
(That .gz file is a 5.8M file -- the largest .gz file that happend to be
in my Downloads folder.)
Since ef7d9c0, shortcut propagation was blocked for blocking modals and
popups. This however is an issue as some blocking modals (like
FilePicker) use shortcuts. This patch allows propagation of shortcuts
but only until the current window.
First, this patch renames the function
`propagate_shortcuts_up_to_application` to `propagate_shortcuts`.
Handling those levels, will allow us to differentiate shortcuts at
`Window` level and `Application` level. Which will be convenient to
handle dialog-specific shortcuts.
Add a list of system and general keyboard shortcuts as well as a list
of tips and tricks to man7 (Miscellanea). Add links to these in the
Help-index to aid discoverability for new users.
Introduced in 2c98eff, support for non-interleaved scans was not working
for frames with a number of MCU per line or column that is odd. Indeed,
the decoder assumed that they have scans that include a fabricated MCU
like scans with multiple components.
This patch makes the decoder handle images with a number of MCU per line
or column that is odd. To do so, as in the current decoder state we do
not know if components are interleaved at allocation time, we skip over
falsely-created macroblocks when filling them. As stated in 2c98eff,
this is probably not a good solution and a whole refactor will be
welcome.
It also comes with a test that open a square image with a side of 600px,
meaning 75 MCUs.
This is an implementation that tries to follow the spec as closely as
possible, and works with Qemu's Intel HDA and some bare metal HDA
controllers out there. Compiling with `INTEL_HDA_DEBUG=on` will provide
a lot of detailed information that could help us getting this to work
on more bare metal controllers as well :^)
Output format is limited to `i16` samples for now.
Negative width/height sizes are not allowed in CSS, so if our layout
algorithm resolves something to a negative size, we have boogs.
Instead of crashing or rendering something very wrong, we now clamp the
values to 0 and whine on the debug log so that someone can go and figure
out how we got the negative values in the first place. :^)
If the previous sibling of an out-of-flow box has been wrapped in an
anonymous block, we now stuff the out-of-flow box into the anonymous
block as well.
