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.
If a call to `document.write` inserts an incomplete HTML tag, e.g.:
document.write("<p");
we would previously continue parsing the document until we reached a
closing angle bracket. However, the spec states we should stop once we
reach the new insertion point.
We were previously embedding the original text to handle the special
case where the text is empty. We generate an extra span to hold the
string "#text" as a placeholder, so that we don't generate a 0px-wide,
unclickable (and therefore uneditable) node. Instead, we can just detect
when this is the case in the Inspector JS.
This further reduces the generated HTML for the Inspector on
https://github.com/SerenityOS/serenity from 1.9MB to 1.8MB (about 94KB,
or 4.7%).
Attribute values may contain HTML, and may contain invalid HTML at that.
If the latter occurs, let's not generate invalid Inspector HTML when we
embed the attribute values as data attributes. Instead, cache the values
in the InspectorClient, and embed just a lookup index into the HTML.
This also nicely reduces the size of the generated HTML. The Inspector
on https://github.com/SerenityOS/serenity reduces from 2.3MB to 1.9MB
(about 318KB, or 13.8%).
We currently support optional integral types, but not nullable types. So
if an IDL contains e.g. "long?", passing null will be coerced to 0.
This will be used by the Inspector, but will also eventually be used by
real IDL interfaces (e.g. HTMLInputElement's selectionStart).
This is required by the CFF spec, and is consistent with what we do for
the encoding 24 lines down.
As far as I can tell, nothing in `Type1FontProgram::rasterize_glyph()`
or in Type1Font.cpp implements the "If an encoding maps to a character
name that does not exist in the Type 1 font pro- gram, the .notdef glyph
is substituted." line from the PDF 1.7 spec (in 5.5.5 Character
Encoding, Encodings for Type 1 Fonts) yet, so this does yet have an
effect.
This adapts our implementation to the editorial change in the temporal
proposal: https://github.com/tc39/proposal-temporal/commit/737baf2d
The changes to CalendarMethodsRecordLookup had already been implemented,
but we had followed the typo in the spec for CalendarMethodsRecordCall.
The issue in CalendarMethodsRecordCall hasn't surfaced yet, as the AOs
using Calendar Methods Record are currently not passing through a String
to represent a Calendar builtin.
No change to test-262.
When a node is removed from the DOM tree, its paintable needs to be
removed to ensure that it is not used to obtain sizes that are no
longer valid.
This change enables the ResizeObserver to send a notification if a node
is removed, as it should, because a removed node now has a size of zero
It should be okay to nullify pointers without concerning
parent/sibling/child relationships because the layout and paintable
trees will be rebuilt following any DOM mutation anyway.
Extends event loop processing steps to include gathering and
broadcasting resize observations.
Moves layout updates from Navigable::paint() to event loop processing
steps. This ensures resize observation processing occurs between layout
updates and painting.
In this change, updating layout and painting are moved to the EventLoop
processing steps. This modification allows the addition of resize
observation dispatching that needs to happen in event loop processing
steps and must occur in the following order relative to layout and
painting:
1. Update layout.
2. Gather and broadcast resize observations.
3. Paint.
