Previously submenus would pop-up on their immediate open ancestors in
cases of limited screen real estate. If the submenu was sufficiently
large, this could make it difficult to navigate back down the menu
stack. Now submenus display on either side of their ancestors, making
it easy to zig-zag up and down menu stacks. This is similar to how
menus operate in many other DEs.
And invalidate the cursor before creating a new drag-and-drop
overlay. Fixes dnd overlay bitmaps failing to draw at the correct
location immedately after changing cursors.
Adds a member to record the last processed mouse buttons. If they
do not include MouseButton::Primary, return early before creating
a new drag and drop client. This fixes race conditions in which
MouseUp events canceling or completing a drop could be swallowed
by Overlay creation or postponed by an executing DragOperation,
leaving the operation in limbo.
Now uses the Selection ColorRole for the active desktop and a
slightly darkened Window for inactive ones. Several themes use
the same color for thread highlighting and inactive windows which
was causing frames to draw without the correct perception of depth.
Other programs use Core::Account::login(), notably su(1), which stopped
working due to a missing "cpath" pledge promise.
This patch moves the /tmp/user/ creation logic to a separate function
that LoginServer can call.
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.
Menu and Window animations can now be disabled and the geometry
overlay made conditional. Shadow options are dependent on the
current theme actually supplying bitmaps, but they provide a fast
way to toggle those that do without having to edit theme files.
SystemEffects are sent to the WindowManager through
set_system_effects() and broadcast to Desktop clients with
update_system_effects(). WindowManager is reponsible for saving,
loading and rebroadcasting effects from WindowServer.ini on
config changes.
Previously we would wait for a separate message confirming that a
wallpaper got set instead of just calling a synchronous api.
I'm guessing that this was a limitation of the IPC system when
WindowServer got ported to using it.
This patch removes the SetWallpaperFinished message and updates the
set_wallpaper api to synchronously return a success boolean.
Before, programs using open_file_url (such as Terminal) would
fail to open any file if its extension (or mime type) wasn't
specified in LaunchServer.ini. This patch now permits it.
Previously, windows without a defined minimum size (or one produced from
the minimum sizes of their contents) would be shrunk down to 0 x 0,
which makes the title buttons stick out the side and become impossible
to interact with.
This patch uses the theme metrics to calculate a minimum size that is as
small as possible while still keeping the title buttons and app icon
usable. This is combined with the minimum size requested by the app
itself.
Switching themes automatically updates the calculated minimum sizes for
all existing windows. As noted, if the new theme has narrower title
buttons then the old minimum is kept, but this shouldn't be noticeable
unless you're looking for it.
Now that the infrastructure of the Graphics subsystem is quite stable,
it is time to try to fix a long-standing problem, which is the lack of
locking on display connector devices. Reading and writing from multiple
processes to a framebuffer controlled by the display connector is not a
huge problem - it could be solved with POSIX locking.
The real problem is some program that will try to do ioctl operations on
a display connector without the WindowServer being aware of that which
can lead to very bad situations, for example - assuming a framebuffer is
encoded at a known resolution and certain display timings, but another
process changed the ModeSetting of the display connector, leading to
inconsistency on the properties of the current ModeSetting.
To solve this, there's a new "master" ioctl to take "ownership" and
another one to release that ownership of a display connector device. To
ensure we will not hold a Process object forever just because it has an
ownership over a display connector, we hold it with a weak reference,
and if the process is gone, someone else can take an ownership.
This header file represents the entire interface between the kernel and
userland, and as such, no longer should be called FB.h but something
that represents the whole graphics subsystem.
Various changes are needed to support this:
- The directory is created by Core::Account on login (and located in
/tmp).
- Service's sockets are now deleted on exit (to allow re-creation)
- SystemServer needs to handle SIGTERM to correctly destroy services.
We now remove default route and set IP address to 0.0.0.0 (Kernel
interprets this as "link down") for all disabled interfaces, so that
a reboot is no longer needed.
Currently in case of multiple notifications, the notifications are
drawn on top of each other when expanded.
The change moves the notificaiton below other notifications
This prevents us from needing a sv suffix, and potentially reduces the
need to run generic code for a single character (as contains,
starts_with, ends_with etc. for a char will be just a length and
equality check).
No functional changes.
Each of these strings would previously rely on StringView's char const*
constructor overload, which would call __builtin_strlen on the string.
Since we now have operator ""sv, we can replace these with much simpler
versions. This opens the door to being able to remove
StringView(char const*).
No functional changes.
Error::from_string_literal now takes direct char const*s, while
Error::from_string_view does what Error::from_string_literal used to do:
taking StringViews. This change will remove the need to insert `sv`
after error strings when returning string literal errors once
StringView(char const*) is removed.
No functional changes.
This commit moves the length calculations out to be directly on the
StringView users. This is an important step towards the goal of removing
StringView(char const*), as it moves the responsibility of calculating
the size of the string to the user of the StringView (which will prevent
naive uses causing OOB access).
