The way we read/write directories is very inefficient, and this doesn't
solve any of that. It does however reduce memory usage of directory
entry vectors by 25% which has nice immediate benefits.
CLion doesn't understand that we switch compilers mid-build (which I
can understand since it's a bit unusual.) Defining __serenity__ makes
the majority of IDE features work correctly in the kernel context.
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.
I honestly don't know the internals of all this and what exactly is
going on, but this fixes compositing of the fullscreen window. By trial
and error I found that specifically m_invalidated_all needs to be set to
false, so it's probably different behaviour in prepare_dirty_rects(),
which depends on that...
Either way, the code composing all windows in non-fullscreen mode calls
Window::clear_dirty_rects() for each, so not doing that for the fullscreen
window as well seems like an oversight.
Fixes#4810.
We only cleared the area not covered by the backing bitmap if a
rendering rectangle intersected with the backing bitmap. But because
we are potentially calling the render function many times we need
to always clear the area not covered by the backing bitmap, whether
it intersects or not.
Fixes#5291
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.
Merely moving a window shouldn't require re-rendering the window
frame anymore now that we cache the rendered frame in bitmaps. This
reduces CPU usage significantly when moving windows.
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.
