We don't actually have a non-trivial vfork implementation, so just
call fork(). As a bonus, vfork() is deprecated in XCode 13.1 when
targeting macOS Big Sur, so this removes a blocker from updating our
macOS CI version.
The evaluation order of method parameters is unspecified in C++, and
so we couldn't rely on parse_statement() being called before
parse_escape() when building a MatchExpression.
With this patch, we explicitly parse what we need in the right order,
before building the MatchExpression object.
This fixes a CI flake we've been seeing lately in TestLibCoreStream.
The solution itself is somewhat of a stop-gap as there are more thorough
event loop threading improvements in the works.
The generator parses metaZones.json to form a mapping of meta zones to
time zones (AKA "golden zone" in TR-35). This parser errantly assumed
this was a 1-to-1 mapping.
The rotate clockwise/rotate counterclockwise actions can be added to
CommonActions since they are repeated in FontEditor, ImageViewer and
PixelPaint. This keeps the shortcuts and icons consistent across
applications.
This snaps vertices to 1/32 of a pixel before rasterization resulting
in smoother movement and less floaty appearance of moving triangles.
This also reduces the severity of the artifacts in the glquake port.
5 bits should allow up to 1024x1024 render targets. Anything larger
needs a different implementation.
Makes CharacterMapFile::load_from_file and CharacterMap::load_from_file
return ErrorOr instead of Optional. This makes them a little nicer to
use and a little easier to read, as they seem to have been approximating
this.
When a user is navigating a table view with arrow keys and a row is
outside of the current view, then scroll_into_view is called, and the
position of the rectangle passed to this should take into account the
column headers.
This can be seen making more pleasant the navigation in the System
Monitor in the Processes view, for example.

This includes:
- Parsing proper LabelledStatements with try_parse_labelled_statement()
- Removing LabelableStatement
- Implementing the LoopEvaluation semantics via loop_evaluation() in
each IterationStatement subclass; and IterationStatement evaluation
via {For,ForIn,ForOf,ForAwaitOf,While,DoWhile}Statement::execute()
- Updating ReturnStatement, BreakStatement and ContinueStatement to
return the appropriate completion types
- Basically reimplementing TryStatement and SwitchStatement according to
the spec, using completions
- Honoring result completion types in AsyncBlockStart and
OrdinaryCallEvaluateBody
- Removing any uses of the VM unwind mechanism - most importantly,
VM::throw_exception() now exclusively sets an exception and no longer
triggers any unwinding mechanism.
However, we already did a good job updating all of LibWeb and userland
applications to not use it, and the few remaining uses elsewhere don't
rely on unwinding AFAICT.
Instead of slapping 0..N labels on a statement like the current
LabelableStatement does, we need the spec's LabelledStatement for a
proper implementation of control flow using only completions - it always
has one label and one labelled statement - what appears to be 'multiple
labels' on the same statement is actually nested LabelledStatements.
Note that this is unused yet and will fully replace LabelableStatement
in the next commit.
Sometimes, pumping the event loop will cause new events to be
generated. For example, an IPC message could be delivered which then
dispatches a new event to be handled by the GUI. To the invoker of
`EventLoop::pump()`, it is not obvious if any events were processed at
all.
Libraries like SDL2 might not have the opportunity to run the event
loop often enough that events can be processed swiftly, since it might
spend time doing other things. This can result in stuttering GUI
interactions.
This changes `EventLoop::pump()` to return the number of processed
events. This functionality will be used by our SDL2 port in another PR.
Previously, only terminal output aligned table column contents
correctly. Now, we apply a `text-align` to each cell. This does not
actually *work* however, since LibWeb's table layout code is not yet
fully functional.
This fixes all failing Date.UTC test262 tests, which failed due to not
handling invalid input and evaluating inputs out of order. But this also
avoids using timegm(), which doesn't work on macOS for years before 1900
(they simply return -1 for those years).
Partially addresses #4651. Date.parse.js still fails.
We currently use Core::DateTime create, which internally uses mktime().
This has the issues pointed out by the (now removed) FIXME, but also has
an issue on macOS where years before 1900 are not supported.
When searching for the locale-specific flexible day period for a given
hour, we were neglecting to handle cases where the period crosses 00:00.
For example, the en locale defines a day period range of [21:00, 06:00).
When given the hour of 05:00, we were checking if (21 <= 5 && 5 < 6),
thus not recognizing that the hour falls in that period.
This impacts text editors' ctrl+left, ctrl+shift+right, ctrl+backspace,
etc..
For example, consider the text "Hello world |", pressing
ctrl+backspace each time.
Before: "hello world |"
"hello world|"
"hello |"
"hello|"
"|"
After: "hello world |"
"hello|"
"|"
Note that this breaks a nice symmetry. Doing ctrl+left and then
ctrl+right doesn't necessarily get you to the same place like it use to.
Before: " hello |"
" hello| "
" hello |" // same as initial
After: " hello |"
"|hello "
" hello| " // different from initial
