The majority of error strings are StringView literals, and it seems
silly to require heap-allocating strings for these.
This idea is stolen from a recent change in fd1fbad :^)
Since BodyInit and Headers are tightly coupled to both Request and
Response, I chose to do all of them at once instead of introducing a
bunch of temporary conversion glue code.
Seems nice to keep these in the same order as the input and have
deterministic codegen of interfaces in LibWeb (for the purpose of
diffing two build revisions, for example).
This API is used by LibWeb's text painter. Bring it up to date with the
glyph width computations performed in draw_text_line() used by other GUI
applications.
These are not yet actually parsed, but detecting them means we at least
don't fail to understand the *actual* format value, which was causing
some CFF fonts to fail to load.
Type1 imposes a stack limit of 24 elements, but Type2 has a limit of 48.
We are better off relaxing the limit of the former in favour of properly
supporting the latter.
There were two issues with how we counted hints with Type2 CharString
commands: the first was that we assumed a single hint per command, even
though there are commands that accept multiple hints thanks to taking a
variable number of operands; and secondly, the hintmask/ctrlmask
commands can also take operands (i.e., hints) themselves in certain
situations.
This commit fixes these two issues by correctly counting hints in both
cases. This in turn fixes cases when there were more than 8 hints in
total, therefore a hintmask/ctrlmask command needed to read more than
one byte past the operator itself.
The Filter class had a few TODO()s that resulted in crashes at runtime.
Since we now have a better way to report errors back to the user let's
use that instead.
This allows us to get rid of an include to LibC/sys/ttydefaults.h in the
Kernel TTY implementation.
Also, move ttydefchars static const struct to another file called
Kernel/API/ttydefaultschars.h, so it could be used too in the Kernel TTY
implementation without the need to include anything from LibC.
This reduces the size of WebIDL::ExceptionOr<T> as follows for a few
different Ts:
WebIDL::ExceptionOr<void>: 48 bytes to 40 bytes
WebIDL::ExceptionOr<JS::Value>: 48 bytes to 40 bytes
WebIDL::ExceptionOr<String>: 56 bytes to 40 bytes
Comes with the usual benefit of saving some space on the stack, as well
as making a situation where both or neither Optionals hold a value
impossible.
The various unwrapping additions are required as we can no longer
construct a ThrowCompletionOr<T> from an Optional<T> - rightfully so.
This would never return an empty optional or non-numeric value, and in
fact every caller as_double()'d the value right away.
Let's make the type match reality instead :^)
Similar to the FontDatabase, this will be needed for Ladybird to find
emoji images. We now generate just the file name of emoji image in
LibUnicode, and look for that file in the specified path (defaulting to
/res/emoji) at runtime.
Currently, if you use the left/right arrow keys to move over a multi-
code point glyph, we will move through that glyph one code point at a
time. This means you can "pause" your movement in the middle of a glyph
and delete a subsection of a grapheme cluster. This now moves the cursor
across the entire cluster.
u64 is not big enough to hold extremely large numbers, such as
4.192938423e+54. This would cause an integer underflow on the radix
index when performing something like `toString(36)` and thus cause an
OOB Array read.
This prevents us setting up the document of a removed browsing context
container (BCC, e.g. <iframe>), which will cause a crash if the
document contains a script that inserts another BCC as this will use
the stale browsing context it previously set up, even if it's
reinserted.
Required by Prebid.js, which does this by inserting an `<iframe>` into
a `<div>` in the active document via innerHTML, then transfers it to
the `<html>` element:
7b7389c5ab/src/utils.js (L597)
This is done in the spec by removing all tasks and aborting all fetches
when a document is destroyed:
https://html.spec.whatwg.org/multipage/document-lifecycle.html#destroy-a-document
See the code comments for a simplified example.
This is not guaranteed to always work correctly as ArgsParser deals in
StringViews and might have a non-properly-null-terminated string as a
value. As a bonus, using StringView (and DeprecatedString where
necessary) leads to nicer looking code too :^)
This feature allows any application to easily install an automatically
updating list of recently open files in a GUI::Menu.
There are three main pieces to this mechanism:
- GUI::Application::set_config_domain(domain): This must be called
before using the recent files feature. It informs the Application
object about which config domain to find the relevant RecentFiles
list under.
- GUI::Menu::add_recently_open_files(callback): This inserts the list
in a menu. A callback must be provided to handle actually opening
the recent file in some application-specific way.
- GUI::Application::set_most_recently_open_file(path): This updates
the list of recently open files, both in the configuration files,
and in the GUI menu.
This adds an option to only detect emoji that should always present as
emoji. For example, the copyright symbol (unless followed by an emoji
presentation selector) should render as text.
`consume_until(foo)` stops before foo, and so does
`ignore_until(Predicate)`, so let's make the other `ignore_until()`
overloads consistent with that so they're less confusing.
Each {} block is now treated as a folding region, so that they can be
collapsed and expanded in TextEditor, HackStudio, and anywhere else
that uses the syntax highlighter. :^)
