When multiple images are dragged and dropped onto the image widget,
QuickShow will use LibDesktop::Launcher to launch a new instance
of QuickShow for each item, rather than spawn a child QuickShow
process for each item with posix_spawn.
This allows `proc` and `exec` pledges to be removed :^)
Prevents discrete values from being skipped when using the mouse
wheel on SpinBoxes and proportional Sliders. Wheel delta can be
accelerated by holding Ctrl.
- Fix headings
- Consistent & more accurate code block language specifiers
- Add some newlines where appropriate
- Remove the strange "run ninja but actually you don't have to run ninja
as ninja install takes care of that" part
- Don't repeat specific build commands in "Ports" section
- Reword "Keymap" section to more generic "Customize disk image"
The system is extremely sensitive to heap allocations during heap
expansion. This was causing frequent OOM panics under various loads.
Work around the issue for now by putting the logging behind
KMALLOC_DEBUG. Ideally dmesgln() & friends would not reqiure any
heap allocations, but we're not there right now.
Fixes#5724.
Otherwise `reposition_cursor()` will move the cursor one character too
far to the right, and since we don't redraw the entire buffer when
the character is inserted at the end, the mistake won't be immediately
fixed by a complete redraw.
Fixes#5722
The previous architecture had a huge flaw: the pointer to the protected
data was itself unprotected, allowing you to overwrite it at any time.
This patch reorganizes the protected data so it's part of the Process
class itself. (Actually, it's a new ProcessBase helper class.)
We use the first 4 KB of Process objects themselves as the new storage
location for protected data. Then we make Process objects page-aligned
using MAKE_ALIGNED_ALLOCATED.
This allows us to easily turn on/off write-protection for everything in
the ProcessBase portion of Process. :^)
Thanks to @bugaevc for pointing out the flaw! This is still not perfect
but it's an improvement.
