These are aliases to `setjmp()` and `longjmp()` on our system,
as our implementations don't modify the signal mask.
This is required for the syzkaller executor process.
Unfortunately, most of the users are inside constructors, (and two
others are inside callback lambdas) so the error can't propagate, but
that can be improved later.
This adds a method `info()` to SoftGPU that returns the name of the
hardware vendor and device name, as well as the number of texture untis.
LibGL uses the returned texture unit count to initialize its internal
texture unit array.
Replaces the GLenum used in RasterizerConfig to select the draw buffer
with a simple boolean that disabled color output when the draw buffer
is set to GL_NONE on the OpenGL side.
We now sample textures from the device owned image samplers.
Passing of enabled texture units has been simplified by only passing a
list of texture unit indices.
This adds two methods, write_texels and read_texels, to the Image class.
Conversion between image formats happens automatically. The layout of
the client image data is passed in via ImageDataLayout struct.
This serves as the storage for all image types. 1D, 2D, 3D, Cube and
image arrays.
Upon construction a full mipmap chain is generated and the image is
immutable afterwards with respect to its layout.
This introduces a new library, LibSoftGPU, that incorporates all
rendering related features that formerly resided within LibGL itself.
Going forward we will make both libraries completely independent from
each other allowing LibGL to load different, possibly accelerated,
rendering backends.
This shortcut let us mute/unmute the player, but it still doesn't update
the volume slider because the actual volume widget can't display a muted
state.
When computing the 'output mix', the Mixer iterates over all client
audio streams and computes a 'mixed sample' taking into account mainly
the client's volume.
This new member and methods will allow us to ignore a muted client
when computing that mix.
The 'muted' methods referred to the 'main mix muted' but it wasn't
really clear from the name. This change will be useful because in the
next commit, a 'self muted' state will be added to each audio client
connection.
The `m_remaining_samples` attribute was underflowing at the end of an
audio stream. This fix guards against the underflow by only decrementing
the attribute when it is greater than zero.
I found this bug because the SoundPlayer userland application was not
correctly detecting when an audio stream was completed. This was
happening because the remaining samples being returned from the client
audio connection was an underflowed 16 bit integer instead of zero.
This fix syncs up the AudioPlayer's internal state for showing
playlist information with the AudioPlayer's GUI. Before, if the
AudioPlayer was opened with a playlist file (.m3u or .m3u8) it would
automatically show the playlist information in the GUI and set the
loop mode to playlist, but the menu options would be unchecked. In
order to hide the playlist information, the menu option would then
have to be toggled twice -- once on and again off.
When a file is opened and scrolled to some position and the user opens
another file, the current scroll position stays the same. That's
disorienting. Therefore, when opening another file, scroll back to the
top.
To support editing of large files it is an advantage to not load the
entire file into memory but only load whatever is needed for display at
the moment. To make it work, file access is abstracted into a socalled
HexDocument, of which there two: a memory based and a file based one.
The former can be used for newly created documents, the latter for file
based editing.
Hex documents now do track changes instead of the HexEditor. HexEditor
only sets new values. This frees HexEditor of some responsibility.
