This switches tracking CPU usage to more accurately measure time in
user and kernel land using either the TSC or another time source.
This will also come in handy when implementing a tickless kernel mode.
As threads come and go, we can't simply account for how many time
slices the threads at any given point may have been using. We need to
also account for threads that have since disappeared. This means we
also need to track how many time slices we have expired globally.
However, because this doesn't account for context switches outside of
the system timer tick values may still be under-reported. To solve this
we will need to track more accurate time information on each context
switch.
This also fixes top's cpu usage calculation which was still based on
the number of context switches.
Fixes#6473
This transitions from synchronous IPC calls to asynchronous IPC calls
provided through a synchronous interface in LibFileSystemAccessClient
which allows the parent Application to stay responsive.
It achieves this with Promise which is pumping the Application event
loop while waiting for the Dialog to respond with the user's action.
LibFileSystemAccessClient provides a lazy singleton which also ensures
that FileSystemAccessServer is running in the event of a crash.
This also transitions TextEditor into using LibFileSystemAccessClient.
File Manager and Spreadsheet had an inconsistent order relative
to other apps (they had a copy-cut-paste order, where every other app
had a cut-copy-paste order).
Pressing tab would focus on the demo widgets instead of switching
between the combo box and color input field. Instead set the focus
policy to NoFocus for all the widgets.
In the Spreadsheet app, selecting a cell and typing something (like
"1") would create an empty editing delegate, set "1" as its value and
immediately select the entire contents of the text box. If your goal
was to type "123", that "1" was selected and will be replaced by "23".
This changes the behavior of TableView to not select the editing
delegate's contents if its creation was a result of a keydown event.
This was required for correctly parsing more than one frame's
height/width data properly. Additionally, start handling failure
a little more gracefully. Since we don't fully parse a tile before
starting to parse the next tile, we will now no longer make it past
the first tile mark, meaning we should not handle that scenario well.
The class that was previously named Decoder handled section 6.X.X of
the spec, which actually deals with parsing out the syntax of the data,
not the actual decoding logic which is specified in section 8.X.X.
The new Decoder class will be in charge of owning and running the
Parser, as well as implementing all of the decoding behavior.
Previously m_constrain_angle could end up not being reset if the
keyup-event was lost, for example when opening a dialog. Instead check
the modifiers in on_mousemove().
Making use of the new FileSystemAccessServer we are able to use
unveil without restricting our ability to open and save files.
A file argument will be unveiled automatically however all other files
require user action via the FileSystemAccessServer to gain access.
This makes sure that scroll_into_view is not called when not necessary,
or when m_layers is empty, which previously caused a crash upon
removing the last layer.
By using the real path for the image, ImageViewer can iterate over the
images in the same directory. Before, this was not possible when
ImageViewer opened from Terminal with a path argument.
