There's currently a small paint glitch for vertical toolbars due to the
way StylePainter::paint_surface() draws a MidGray line at the bottom of
whatever a "surface" is supposed to be.
I'll be reconstructing parts of the VisualBuilder application here and
then we can retire VisualBuilder entirely once all the functionality
is available in HackStudio.
Now the userspace page allocator will search through physical regions,
and stop the search as it finds an available page.
Also remove an "address of" sign since we don't need that when
counting size of physical regions
You can now press Ctrl+Shift+Up/Down in a GTextEditor and the currently
selected line(s) will all move together one step up/down.
If there is no selection, we move the line with the cursor on it. :^)
Since on_change handlers can alter the text document we're working on,
we have to make sure they've been run before we try looking at spans.
This fixes some flakiness when a paint happened before HackStudio had
a chance to re-highlight some C++ while editing it.
The design where clients of GTextEditor perform syntax highlighting in
the "arbitrary code execution" on_change callback is not very good.
We should find a way to move highlighting closer to the editor.
This was too noisy and important-sounding, when it doesn't really
matter that much. It's not the end of the world if symbolication fails
for one reason or another.
Since NonnullRefPtr and NonnullOwnPtr cannot be null, it is pointless
to convert them to a bool, since it would always be true.
This patch makes it an error to null-check one of these pointers.
It should be possible for the CSS parser to fail, and we'll know it
failed if it returns nullptr. Returning RefPtr's makes it actually
possible to return nullptr. :^)
This simple helper escapes '<', '>' and '&' so they can be used in HTML
text without interfering with the parser.
Use this in IRCClient to prevent incoming messages from messing with
the DOM :^)
This function parses a partial DOM and returns it wrapped in a document
fragment node (DocumentFragment.)
There are now two entrances into the HTML parser, one for parsing full
documents, and one for parsing fragments. Internally the both wrap the
same parsing function.
It's not safe to use a raw pointer for Process::m_tty. A pseudoterminal
pair will disappear when file descriptors are closed, and we'd end up
looking dangly. Just use a RefPtr.
Scheduling priority is now set at the thread level instead of at the
process level.
This is a step towards allowing processes to set different priorities
for threads. There's no userspace API for that yet, since only the main
thread's priority is affected by sched_setparam().
