ECMA-402 requires validating user input against the EBNF grammar for
Unicode locales described in TR-35: https://www.unicode.org/reports/tr35
This commit adds validators for that grammar, as well as other helper to
e.g. canonicalize a locale string.
The Unicode standard publishes a database known as the Common Locale
Data Repository (CLDR). This is a massive set of data from which anyone
implementing Unicode's Technical Standard #35 may generate their
implementation: https://www.unicode.org/reports/tr35/
This commit updates LibUnicode to download the compressed database and
extract a small subset. That subset is used to generate a list of
available locales and the territories (AKA regions) associated with each
locale.
This controls how fetched texels are combined with the color that was
produced by a preceding texture unit or with the vertex color if it is
the first texture unit.
Currently only a small subset of possible combine modes is implemented
as required by glquake.
This sets the length of a row for the image to be transferred. This
value is measured in pixels. When a rectangle with a width less than
this value is transferred the remaining pixels of this row are skipped.
Previously it was returning an "auto" length. This caused all the new
"initial" values to effectively turn into auto values long before layout
had a chance to resolve them.
This broke replaced elements with intrinsic size but no specified width
or height, and is the reason that Mr. ACID2 temporarily lost his eyes.
This API lets applications specify which configuration domains they
will be accessing throughout their lifetime. It works similarly in
spirit to the kernel's pledge().
You cannot pledge_domains() more than once, and once you have used it,
it's no longer possible to access any other configuration domain.
This is obviously just a first cut of this mechanism, and we may need
to tweak it further as we go.
It's not possible to connect to ConfigServer without having an event
loop available. This VERIFY makes it much easier to understand why
things are not working. :^)
This static bool getter can be used to VERIFY that an event loop exists,
in situations where one is expected.
This is helpful if the absence of an event loop would generate strange
and/or loud errors that don't immediately point to this as a cause.
ConfigServer is an IPC service that provides access to application
configuration and settings. The idea is to replace all uses of
Core::ConfigFile with IPC requests to ConfigServer.
This first cut of the API is pretty similar to Core::ConfigFile.
The old:
auto config = Core::ConfigFile::open_for_app("App");
auto value = config->read_entry("Group", "Key");
The new:
auto value = Config::read_string("App", "Group", "Key");
ConfigServer uses the ~/.config directory as its backing store
and all the files remain human-editable. :^)
Calling sigprocmask() through the PLT requires setting the ebx register
to the address of the global offset table, otherwise chaos ensues. Also
the value of the ecx register was assumed to be preserved across that
function call despite the fact that it is caller-saved in the x86
calling convention.
This isn't 100% spec complaint, as it should use glyph_height()
depending on what the value of the writing-mode is, but we haven't
implemented it yet, so I think it'll be good enough for now.
This can be tested in https://wpt.live/css/css-values/ch-unit-008.html
Other css-unit tests fail as:
- 001 shows an issue related to a renderer (looks to me like you can't
pass a width and height property to a span -- adding `display: block`
to it passes the test),
- 002-004 and 009-012 use mentioned writing-mode,
- 016-017 loads custom fonts, which we also don't support (yet).
When property() previously would have returned an InitialStyleValue, we
now look up what the initial value would be, and return that instead.
We also intercep 'inherit', but inheritance is not implemented yet so we
just return nothing.
This does cause a regression on Acid2: The eyes no longer appear, and I
am not sure why. :^(
Since we have initial-value data in Properties.json already, it makes
sense to use that instead of needing to duplicate the same information
in ComputedValues.h
However, converting a StyleValue to the kind of types used in
InitialValues is non-trivial. So this may or may not actually be useful.
This bug was discovered via OSS fuzz, it's possible to fall through
to this assert with a char_size == 1, so we need to account for that
in the VERIFY(..).
Repro test case can be found in the OSS fuzz bug:

This patch adds OutOfProcessWebView::run_javascript(StringView).
This can be used by the OOPWV embedder to execute arbitrary JavaScript
in the top-level browsing context on the WebContent process side.
Added a test to ensure the behavior stays the same.
We now throw on a direct usage of an escaped keywords with a specific
error to make it more clear to the user.
This iterates the fragments of the containing block, and paints their
outlines if they are descendants of the InlineNode.
If multiple fragments are adjacent, eg:
```html
<span><b>Well</b> hello <i>friends!</i></span>
```
...then we get a double-thick outline between "Well", " hello " and
"friends!", but we can come back to this after we implement
non-rectangular outlines for the `outline` CSS property.
These should all have a name with an empty string. Not only does test262
verify this, but it also verifies that (for the executor) the name
property is defined after the length property.
PerformPromiseAll, PerformPromiseAny, PerformPromiseAllSettled, etc, all
have very similar iteration loops. To avoid duplicating this rather
large block of code, extract the common functionality into a separate
method.
The element-resolving functions on the Promise constructor are all very
similar. To prepare for more of these functions to be implemented, break
out common parts into a base class.
