The former automatically adapts the prefix to binary and octal
output, and is what we already use in the majority of cases.

I ran it 4 times (until it stopped changing things) since each
invocation only converted one instance per line.
No behavior change.
Height definiteness is now preserved as intended by CSS-SIZING-3
(assuming I've understood it correctly) and not implicitly granted by
layout algorithms when they assign height.
For the specific special/magical cases where some sizes become definite
during layout, the preceding commits have made them explicit in code.
This fixes a number of flex layout issues where we were previously
resolving percentage values against post-layout flex container heights,
but other browsers don't.
Fixing this function will be quite an undertaking since a *lot* of code
relies on set_content_width() implicitly flipping the definiteness of
the width. It is wrong though, so we do need to fix it eventually.
In particular, these two interesting cases:
- The containing block of an abspos box is always definite from the
perspective of the abspos box.
- When resolving abspos box sizes from two opposing fixed insets,
we now mark those sizes as definite (since no layout was required
to resolve them).
The whole way we lay out SVG content is ad-hoc, so this doesn't follow
any particular spec. However, our viewport transform logic depends on
having definite sizes, so let's just mark them as such for now.
This will be required for percentages to resolve against it correctly
after we make set_content_height() not automatically mark heights as
definite sizes.
The CSS-FLEXBOX-1 spec has a bunch of special cases where sizes are
considered definite after reaching a specific point of the layout
algorithm.
Before this change, we were relying on set_content_width/height also
implicitly marking those content sizes as definite.
To prepare for that implicit behavior going away, this patch makes
the special cases explicit.
Before this change, we were always assigning the calculated height to
each block container after laying it out in BFC.
This should really only happen during intrinsic sizing, since that is
how measurements are communicated to the client there.
QUrl::toString reverses the Unicode->ASCII conversion that already
occurred here. The text of m_location_edit is already in the format we
expect, so let's just convert QString->AK::URL directly, instead of
taking the detour QString->QUrl->AK::URL
We should still add an informational message about when this happens
before we even get here - but we still shouldn't be able to locate a
place to apply a hunk as it ends up producing unexpected results where
the patch is prepended to the existing file.
It's not always important to verify what the contents of stdout are when
adding a patch test - especially if it's not exactly what we want it to
be, so make this optional when running patch for a test.
Check if we have a cmap before dereferencing it again.
Fixes a crash on page 8 of 0000188.pdf now that the font no
longer fails to load to due to a missing name table.
Looks like this is a Type2 truetype font, where we don't provide
an external cmap. How this font is supposed to work without a cmap
I don't know -- but for now, we no longer crash on it, and draw
some of the text with the previous font (which happens to work
fine in this particular case).
Kind of reverts #21675, but #21744 made that better
4 of my 1000 test PDFs complained "Invalid table offset or length in
font" before.
For example, in 0000203.pdf, these tags had length 0: 'cvt ', 'fpgm',
'prep', 'name', 'OS/2'. (Generally it's tables that aren't needed
for rendering PDFs, and the PDF writer figured it's easier to zero
out these tables instead of omitting them altogether for some reason.)
Increases number of PDFs that render without diagnostics from
765 to 767.
It is sometimes truncated in fonts embedded in PDFs, and the data
is not needed to render PDFs. 2 of my 1000 test PDFs used to
complain "Could not load OS2 v1: Not enough data" and 1
"Could not load OS2 v2: Not enough data" before.
Increases number of PDFs that render without diagnostics from
764 to 765 (and decreases the number of distinct error messages
from 27 to 25).
It is sometimes truncated in fonts embedded in PDFs, and the data
is not needed to render PDFs. 26 of my 1000 test files complained
"Could not load Hmtx: Not enough data" before.
Increases number of PDFs that render without diagnostics from
743 to 764.
It is often missing in fonts embedded in PDFs. 75 of my 1000 test
files complained "Font is missing Name" when trying to read fonts
before.
Increases number of PDFs that render without diagnostics from
682 to 743.
Before, we used to reject profiles where the creation datetime was
invalid per spec. But invalid dates happen in practice (most commonly,
all fields set to 0). They don't affect profile conversion at all,
so be lenient about this, in exchange for slightly more wordy code
in the places that want to show the creation datetime.

We only need to know that the Global Object of the environment is an
event target in order to dispatch an event on it. This resolves a FIXME
where we assumed that the only type of Global in LibWeb is HTML::Window.
The default canvas size is 300x150 pixels. If the element or document
we are trying to screenshot for the WebDriver is not at least that size,
then we will create a canvas that is wider or taller than the actual
element we are painting, resulting in a bunch of transparent pixels
falling off the end.
This fixes 14 WPT css/CSS2/floats tests that we run in CI, and
presumably a ton of other reftests in the WPT test suite.
With this change "max-width: max-content" is treated as "none" when
the available width is also "max-content". This fix prevents a stack
overflow in the grid track size maximization algorithm by avoiding
recursive calls to calculate_max_width() when determining the maximum
grid container size.
Exif metadata have two tags to store the pixel density along each axis.
If both values are different and no action is taken, the resulting image
will appear deformed. This commit scales the displayed bitmap
accordingly to these tags in order to show the image in its intended
shape. This unfortunately includes a lot of plumbing to get this
information through IPC.
We have a 5 second timeout between a user-activated event occurring and
an activation-gated API being invoked in order for that API to succeed.
This is quite fine in normal circumstances, but the machines used in CI
often exceed that limit (we see upwards of 10 seconds passing between
generating the user-activated event and the API call running).
So instead of generating a user-activated event, add a hook to allow
tests to bypass the very next activation check.
Instead of having Call refer to a range of VM registers, it now has
a trailing list of argument operands as part of the instruction.
This means we no longer have to shuffle every argument value into
a register before making a call, making bytecode smaller & faster. :^)
By handling common cases like Int32 arithmetic directly in the
instruction handler, we can avoid the cost of calling the generic helper
functions in Value.cpp.
Instead of splitting the postfix variants into ToNumeric + Inc/Dec,
we now have dedicated PostfixIncrement and PostfixDecrement instructions
that handle both outputs in one go.
