This patch adds a new Editing-Mask type to layers. This kind of mask
is used to restrict changes on the content bitmap only to areas where
the mask is drawn. The intensity of a pixel change is controlled by the
alpha-value of the mask.
Furthermore a function to invert and clear masks has been introduced.
When a new mask is created for a layer the edit mode of the layer is
also changed to Mask so that the user can immediately start to draw the
mask.
This change was a long time in the making ever since we obtained sample
rate awareness in the system. Now, each client has its own sample rate,
accessible via new IPC APIs, and the device sample rate is only
accessible via the management interface. AudioServer takes care of
resampling client streams into the device sample rate. Therefore, the
main improvement introduced with this commit is full responsiveness to
sample rate changes; all open audio programs will continue to play at
correct speed with the audio resampled to the new device rate.
The immediate benefits are manifold:
- Gets rid of the legacy hardware sample rate IPC message in the
non-managing client
- Removes duplicate resampling and sample index rescaling code
everywhere
- Avoids potential sample index scaling bugs in SoundPlayer (which have
happened many times before) and fixes a sample index scaling bug in
aplay
- Removes several FIXMEs
- Reduces amount of sample copying in all applications (especially
Piano, where this is critical), improving performance
- Reduces number of resampling users, making future API changes (which
will need to happen for correct resampling to be implemented) easier
I also threw in a simple race condition fix for Piano's audio player
loop.
The immutability of the string is not relevant here, since the string
we're given was allocated in the IPC serialization layer and will be
destroyed shortly afterwards. Additionally, noone relies on
DeprecatedString-specific functionality. This will make it easier to
convert the IPC layer itself to String later on.
This commit changes the variables used to represent the size and
progress of downloads from u32 to u64. This allows `pro` and
`Browser` to report the total size and progress of a download
correctly for downloads larger than 4GiB.
The data we want to send out of the WebContent process is identical for
audio and video elements. Rather than just duplicating all of this for
audio, generalize the names used for this IPC for all media elements.
This also encapsulates that data into a struct. This makes adding new
fields to be sent much easier (such as an upcoming field for muting the
element).
Since these are stored as numbers, and "1,2,3,5,6" is a bit meaningless
to anyone who looks at this code, the default set of visible columns is
provided as it was before, by them all being visible except a couple
that are specifically hidden.
The callback is wrapped in a debounce() so that if set_visible_columns
() is called, we'll just save the value once instead of doing so for
each column changed.
We need to add another pair of parenthesizes when propagating an
initialization of ItemListModel, because a comma in a template argument
would work as a separator of macro arguments, leading to a compile
error.
The minimal build configuration doesn't include HackStudio and
SystemMonitor refused to run after trying to unveil a not exiting file.
This change will just ignore this specific error for this specific file
as if nothing really happened.
The ability to quickly debug a process in HackStudio is not the main
feature of the application and HackStudio itself is rather heavy to be
put in the minimal configuration.
Additionally, I find it unnecessary to disable/hide the 'Debug in
HackStudio' action because build configurations are mostly for testing
purposes anyway. You will get a 'No such file or directory' error in the
console after activating the action though. :^)
Note that this fixes contradictory default values for group
"Preferences", key "Home". This is exactly the kind of errors I want to
prevent with this new style.
The hope is that this can later be used to:
- verify that all accesses to the same key use the same default value,
- and extract the default values more easily.
The implemented cloning mechanism should be sound:
- If a PartitionTable is passed a File with
ShouldCloseFileDescriptor::Yes, then it will keep it alive until the
PartitionTable is destroyed.
- If a PartitionTable is passed a File with
ShouldCloseFileDescriptor::No, then the caller has to ensure that the
file descriptor remains alive.
If the caller is EBRPartitionTable, the same consideration holds.
If the caller is PartitionEditor::PartitionModel, this is satisfied by
keeping an OwnPtr<Core::File> around which is the originally opened
file.
Therefore, we never leak any fds, and never access a Core::File or fd
after destroying it.
The "Crop Image to Selection" action will now crop all layers within
the current selection.
Any layers outside of the current selection are deleted.
If there are no layers within the current selection, a new layer the
same size as the selection is created, which has the same name as the
current active layer.
