This proposal has been merged into the main ECMA-262 spec. See:
4a32716
Note this includes some editorial changes made when the proposal was
merged into the main spec, but are not in the proposal spec.
This was accidentally broken in
ac40197047, after which we started
installing headers into a `LibCrypt` subdirectory instead.
`serenity_install_headers("")` is really the only thing that we need
from `serenity_libc`, so just replicate that manually.
This fix addresses issue where, if request headers contain
"Connection: keep-alive", we keep socket open without letting client
know that we support keep-alive connections. This can result in a
large number of open and unused sockets.
Before this change `apply_clip_overflow_rect` might crash trying to
access `clip_rect` that does not have value because we currently
support calculation of visible rectangle when `overflow: hidden`
is applied for both axis.
This is a special case of the sample count field in the header which we
treated as a format error before. Now we just take care to check stream
EOF before reading chunks.
This makes the final FLAC spec test pass, making us one of the most
compliant loaders! :^)
We report a rounded up PCM sample format to the outside, but use the
exact bit depth as specified in header and frames.
This makes the three FLAC spec tests with a a bit depth of 20 pass.
As the user might want to have interactions with LibGUI while handling
errors, this code should be executed in the original `EventLoop`.
Similarly to what is done with the error-free path.
"Improve" is an understatement, since this commit makes all FLAC files
seek without errors, mostly with high accuracy, and partially even fast:
- A new generic seek table type is introduced, which keeps an
always-sorted list of seek points, which allows it to use binary
search and fast insertion.
- Automatic seek points are inserted according to two heuristics
(distance between seek points and minimum seek precision), which not
only builds a seek table for already-played sections of the file, but
improves seek precision even for files with an existing seek table.
- Manual seeking by skipping frames works properly now and is still used
as a last resort.
- We were using primitive versions of mkstemp and mkdtemp, they have
been converted to use LibCore::System.
- If an error occurred whilst creating a temporary directory or file, it
was thrown and the program would crash. Now, we use ErrorOr<T> so that
the caller can handle the error accordingly
- The `Type` enumeration has been made private, and `create_temp` has
been "split" (although rewritten) into create_temp_directory and
create_temp_file. The old pattern of TempFile::create_temp(Type::File)
felt a bit awkward, and TempFile::create_temp_file() feels a bit nicer
to use! :^)
Once the Core::Filesystem PR is merged (#17789), it would be better for
this helper to be merged in with that. But until then, this is a nice
improvement.
At the moment, we can't resolve CSS calc() values without having a
LayoutNode. The new StyleProperties::line_height() overload was trying
to do exactly that, which led to an assertion.
This patch makes `line-height: calc(...)` behave the same as
`line-height: normal` for now and adds a FIXME.
If the PaintableBox had children, but we didn't hit any of them, we
default to saying that you hit the PaintableBox itself.
However, if said PaintableBox has `pointer-events: none`, we should
say nothing was hit, so that the hit testing can continue.
This fixes an issue where Discord server icons were not clickable.
Previously, empty text boxes would fall back to the min-height: 16px
set on the <input> element. As soon as there is any content they
would usually gain height because the line height of that text is
more than 16px (depending on the font/font-size used).
Now they use height: 1lh for the inner div (which contains the
actual text), which matches the exact height of 1 line of content.
These are currently initialized in a [[gnu::constructor]], which has a
weird initialization order. These constructors are invoked before main()
and, incidentally, before any user-defined default constructors of the
static strings they are initializing.
This will become an issue when these strings are ported to FlyString,
which has a user-defined default constructor. In that scenario, when the
FlyString constructor is executed after the [[gnu::constructor]], the
strings will be "reset" to the empty string.
Instead of relying on a non-standard compiler extension here, let's just
initialize these strings explicitly during main-thread VM creation, as
this now happens in WebContent's main().
When CallbackType::callback was converted from Object& to NNGCP<Object>,
we started comparing the addresses of NNGCPs instead of the addresses of
Objects.
That broke the Discord login form, and this patch fixes it.
Regression from 7c0c1c8f49.
Explicitly check is_viewport() instead of looking at the corresponding
DOM node. (The viewport has the DOM document as its DOM node, but that's
not obvious from context here.)
Checkedness of an input element can influence sibling style, as well as
style of their children, when they use the `:checked` pseudo-class in
combination with a kind of sibling selector. That means its not
sufficient to just invalidate the input elements on style.
This is actually more commonly observable than one might expect, because
this pattern is often used as a JS-free toggle solution for things like
menus.
We don't support all parts of the font formats we assume as "supported"
in the CSS parser. For example, if an open type font has a CFF table, we
reject loading it. This meant that until now, when such an
unsupported-supported font url was first in the list of urls, we
couldn't load it at all, even when we would support a later url.
To resolve that, try loading all font urls one after each other, in case
we are not able to load the higher priority one.
This also resolves a FIXME related to spec compliant url prioritization.
Our CSS parser already filters and prioritizes font src urls in
compliance with the spec. However, we still had to resort to brittle
file extension matching, because some websites don't set the `format`
and if the first url in a src list happened to be one we don't support,
the font could not be loaded at all. This now is unnecessary because we
can try and discard the urls instead.
This fixes an issue where e.g `height: 100%` on a flex item whose
container has indefinite height was being resolved to 0. It now
correctly behaves the same as auto.
We were storing indices into OSC escape sequences as `u8`s, which
overflow at a length of just 256 characters. This caused a crash when
parsing OSC 8 hyperlinks pointing to long filenames.
We were missing some unwind related control flow paths, and followed
some in improper ways, leading us to access a dead unwind frame in some
cases, as well as generating a technically wrong CFG.
This reorders the ways EnterUnwindContext works and alleviates those
errors.
This patch parses enough of GPOS tables to be able to support the
kerning information embedded in Inter.
Since that specific font only applies positioning offsets to the first
glyph in each pair, I was able to get away with not changing our API.
Once we start adding support for more sophisticated positioning, we'll
need to be able to communicate more than a simple "kerning offset" to
the clients of this code.
