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).
When compiling with Lagom, we give both LibWebSocket and the WebSocket
IPC service the Lagom:: prefix as an alias, but strip the Lib from all
library target names before applying the prefix. This creates a conflict
when external projects used the aliased name between the server and the
library. Give WebSocket a name that deconflicts it, but keep the binary
name the same, /bin/WebSocket.
Add overrides for serenity_bin and serenity_lib to allow the actual
CMakeLists.txt from Userland to be used to build as many services as
possible without adding more clutter to Meta/Lagom/CMakeLists.txt
At least macOS has a non-standard sin_len field at the front of
the struct that Linux and Serenity do not. On BSDs, the
sin_len field must be initialized to the size of the structure.

This commit has no behavior changes.
In particular, this does not fix any of the wrong uses of the previous
default parameter (which used to be 'false', meaning "only replace the
first occurence in the string"). It simply replaces the default uses by
String::replace(..., ReplaceMode::FirstOnly), leaving them incorrect.
This makes the page automatically update to reflect the system theme
when in "Color Scheme > Follow System Theme" mode without having to
manually cause a style update.
I already fixed the crash from this in #14470, but didn't fully fix
the issue. Currently the browser just avoids sending the
inspect_dom_node() IPC call for non-visible nodes.
The main problem with this is it means the browser keeps displaying
the overlay for the previously selected node. This commit fixes
the crash in the WebContent side, so the IPC call can still be made
and the selection correctly updated.
These functions were changed to synchronous in #13870 but
the async_ versions were still being called. This led to
frequent crashes when loading local files in Browser.
To achieve this goal:
- The Browser unveils "/tmp/portal/filesystemaccess"
- Pass the page through LoadRequest => ResourceLoader
- ResourceLoader requests a file to the FileSystemAccessServer via IPC
- OutOfProcessWebView handles it and sends a file descriptor back to
the Page.
This allows us to make sure that those operations are performed
in the right order. Affected functions are:
- add_window_stealing_for_client
- set_window_parent_from_client
- remove_window_stealing_for_client
- remove_window_stealing
Before this patch, when you called FileSystemAccessServer::Client::try_*
twice, the second call used the same variable to store the promise. This
"race condition" is now solved using a HashMap, to store multiple
parallel requests.
