At the point at which we try to map the Region it was already added to
the Process region tree, so we have to make sure to remove it before
freeing it in the mapping failure path, otherwise the tree will contain
a dangling pointer to the free'd instance.
This fixes an issue where failing the fork due to OOM or other error,
we'd end up destroying the Process too early. By the time we got to
WaitBlockerSet::finalize(), it was long gone.
Until now, our only backup plan when running out of physical pages
was to try and purge volatile memory. If that didn't work out, we just
hung userspace out to dry with an ENOMEM.
This patch improves the situation by also considering clean, file-backed
pages (that we could page back in from disk).
This could be better in many ways, but it already allows us to boot to
WindowServer with 256 MiB of RAM. :^)
This fixes an issue where the window resize overlay would display
inaccurate "columns x rows" after a font change. This happened because
we kept using size increments derived from the original font.
This patch allows to insert "%uid" in `IPC_CLIENT_CONNECTION`
declaration and in SystemServer's ini files. This pattern is replaced
then replaced by the UID of the owner of the service. It opens a path
for seamlessly managed, per-user portal.
The `/tmp/user` directory is owned by root, this solution prevents
malicious users to interfere with other users' portals.
This commit also moves `launch`'s portal in the user directory.
The median filter replaces a pixel with the median of all pixels
(usually grey value is used) in a square neighborhood. This is a
standard image processing filter used for denoising, as despite its
simplicity it can e.g. retain edges quite well.
The first implementation is quite inefficient mostly to environmental
constraints. Due to how images are passed to the processing function,
two unnecessary copies happen. And because there's no fast sorting
algorithm for small arrays (insertion sort) yet, quick sort needs to be
used which is quite slow on this scale.
This makes modifications in FontEditor more visible, both so you know
what you've changed, and for taking a handy "here's what's changed"
screenshot for a font PR. :^)
The background color for new glyphs is green, modified glyphs is blue,
and deleted glyphs is red. The changes persist until you load a new
font file, so you can continue saving your work as you go and still be
able to take a convenient screenshot at the end.
I didn't feel like this one use was enough to add 3 new color roles to
themes, so to make this look decent on dark themes, it detects if the
theme is marked as dark, and uses darker colors for the highlights
which look nice with a light text color.
