`length` is only the (trimmed) size of the word vector, so we have to
multiply it with the size of each element to ensure all bytes are
compared.
Fixes#5335.
I noticed that programs running in the terminal had an open file
descriptor for the system theme buffer, inherited from the Terminal.
Let's be nice and always mark incoming fds with FD_CLOEXEC.
In some circumstances (like template selection dialogs,) displaying as much
item label as possible, on all items, may be desired.
The default setting is 'false', which matches the default behaviour from before;
only wrapping on hover or selection.
Allocate GC heap blocks with mmap(MAP_RANDOMIZED) for ASLR.
This may very well be too aggressive in terms of fragmentation, and we
can figure out ways to scale that back once it becomes a big problem.
For now, this makes the GC heap a lot less predictable for an attacker.
This replaces the manual watch_file and Notifier handling with the new
Core::FileWatcher wrapper, which reduces the manual handling and makes
the code easier to reason about :^)
This wrapper abstracts the watch_file setup and file handling, and
allows using the watch_file events as part of the event loop via the
Core::Notifier class.
Also renames the existing DirectoryWatcher class to BlockingFileWatcher,
and adds support for the Modified mode in this class.
We now also look at the available declarations from included header
files when autocompleting names.
Additionally, you can now request autocomplete on an empty token, which
brings up all available names, starting from the inner-most scope.
Text <input> fields will now generate a basic shadow DOM and attach it
to the input element.
The shadow DOM contains a <div> with some inline style, and an always-
editable text node inside it. Accessing the "value" attribute on such
an input element will get/set the value from that text node.
This is really cool, although not super stable since HTML editing is
not super stable. But it's a start! :^)
Elements with shadow roots will now recurse into those shadow trees
while building the layout tree.
This is the first step towards basic Shadow DOM support. :^)
The approach of attaching sub-widgets to the web view widget was only
ever going to work in single-process mode, and that's not what we're
about anymore, so let's just get rid of WidgetBox so we don't have the
dead-end architecture hanging over us.
The next step here is to re-implement <input type=text> using LibWeb
primitives.
We'll want to remove the LibGUI dependency from the WebContent process.
This is the first basic step of removing unnecessary LibGUI includes
and swapping out GUI::Painter for Gfx::Painter.
We weren't properly handling switching between having a shadow and
not having a shadow when switching themes. This allows an empty string
in the theme configuration for a shadow path, meaning no shadow should
be rendered.
The WebContent process was redoing page layout every time you scrolled
the page. This was a huge CPU hog for no reason. Fix this by only doing
a relayout when the viewport is resized, not when it moves around.
Also stop exposing the DOM cursor as a mutable reference on Frame,
since event handling code was using that to mess with the text offset
directly. Setting the cursor now always goes through the Frame where
we can reset the blink cycle appropriately.
This makes cursor movement look a lot more natural. :^)
This implements simple window shadows around most windows, including
tooltips. Because this method uses a bitmap for the shadow bits,
it is limited to rectangular window frames. For non-rectangular
window frames we'll need to implement a more sophisticated algorithm.
