After dispatching a "change" event due to the checked state being
modified, we may have been removed from the layout tree.
Make LayoutCheckBox protect itself to prevent this from crashing.
Also, add a little test page for checkboxes. :^)
This is implemented entirely inside LibWeb, there is no GUI::CheckBox
widget instantiated, unlike other input types. All input types should
be moved to this new style of implementation.
To implement form controls internally in LibWeb (necessary for multi
process forms), we'll need the ability to handle events since we can't
rely on LibGUI widgets anymore.
A LayoutNode can now override wants_mouse_events() and if it returns
true, it will now receive mousedown, mousemove and mouseup events. :^)
We got ourselves into a mess by making widgets override the window
cursor whenever they wanted a custom cursor. This patch introduces a
better solution to that issue: per-widget override cursors.
Each widget now has an override cursor that overrides the window
cursor when that widget is hovered.
Since "rings" typically refer to code execution and user processes
can also execute in ring 0, rename these functions to more accurately
describe what they mean: kernel processes and user processes.
The ring is determined based on the CS register. This fixes crashes
being handled as ring 3 crashes even though EIP/CS clearly showed
that the crash happened in the kernel.
It has been possible for a signal to arrive in between us checking
g_interrupted and exiting - sucessfully, even though we were interrupted.
This way, if a signal arrives before we reset the disposition, we
will reliably check for it later; if it arrives afterwards, it'll
kill us automatically.
It wasn't actually possible to call
const LogStream& operator<<(const LogStream&, ReadonlyBytes);
because it was shadowed by
template<typename T>
const LogStream& operator<<(const LogStream& stream, Span<T> span);
not sure how I didn't find this when I added the overload.
It would be possible to use SFINAE to disable the other overload,
however, I think it is better to use a different method entirely because
the output can be very verbose:
void dump_bytes(ReadonlyBytes);
In addition to being the proper POSIX etiquette, it seems like a bad idea
for issues like the one seen in #3428 to result in a kernel crash. This patch
replaces the current behavior of failing on insufficient buffer size to truncating
SOCK_RAW messages to the buffer size. This will have to change if/when MSG_PEEK
is implemented, but for now this behavior is more compliant and logical than
just bailing.
This makes Terminal::scroll_up() O(1) instead of O(n) in the
size of the history. (It's still O(n) in the size of visible
lines.)
Reduces time to run `disasm /bin/id` with the default terminal
window size from 530ms to 409ms (min-of-5) on my system.
DC and AC table IDs read in the scan header segment weren't validated
against the IDs of Huffman tables read in the DHT segment. This caused
an OOB read when a Huffman table was accessed using the ID read in the
scan header segment. Furthermore, the decoder now replaces the old DC
or AC table if a redefinition has been found prior to the scan header.
Fixes#3439.
If a scrollbar doesn't have a scrubber (because the view it scrolls is
large enough to display all its contents without scrolling), then
it ignores all clicks. We shouldn't draw a hover highlight that suggests
clickability in that case.
This patchset adds the following to the manpage:
- Mention `if` expressions.
- Add section about subshells
- Mention that control structures can now be used as commands
- Update the grammar.
- Fix small header size mistake with "Example"'s being larger than their
containing sections.
