This is so they can find their associated resources and it's
the same behavior as in Lagom.
This also required changing some tests so that they could
write their resources in a writable location.
If we consumed whitespace and/or comments after a RegexLiteral token,
the following token must not be RegexFlags - no whitespace or comments
are allowed between the closing / and the flag characters.
Fixes#8201.
This fixes#8133.
Ext2FSInode::remove_child() searches the lookup cache, so if it's not
initialized, removing the child fails. If the child was a directory,
this led to it being corrupted and having 0 children.
I also added populate_lookup_cache to add_child. I hadn't seen any
bugs there, but if the cache wasn't populated before, adding that
one entry would make it think it was populated, so that would cause
bugs later.
This replaces the naive copy algorithm that only supported rectangular
and 100% opaque selections with a more general approach that supports
any shape and alpha value.
Note that we now make a brand new bitmap with a hardcoded format instead
of just cropping the layer's existing bitmap. This is done to ensure
that the final clipboard image will have an alpha channel.
A "feather" value sets by how much the borders of the selection will be
smoothed, and a "mode" value sets how the newly selected region will
interact with an existing image selection (if any).
The Mask class represents an opacity mask over a rectangular section
of an image, linking every pixel to an alpha value ranging from 0 (not
selected) to 255 (fully selected). "Partially selected" pixels can be
used to simulate anti-aliased curves.
This class will be used as the basis for the new non-rectangular
selection feature.
My previous PR had a small error in rebasing and removed a line in
open_file_url. This caused opening text files from the terminal to
always open with an empty TextEditor.
This commit fixes that problem!
This patch makes the following renames:
- get_from_scope() => get_from_environment_record()
- put_to_scope() => put_into_environment_record()
- delete_from_scope() => delete_from_environment_record()
This patch makes the following name changes:
- ScopeObject => EnvironmentRecord
- LexicalEnvironment => DeclarativeEnvironmentRecord
- WithScope => ObjectEnvironmentRecord
Color palettes can now be stored in and read from files. The default
palette will be read from `/res/color-palettes/default.palette`
instead of being hard-coded in PaletteWidget.
The file format is one color per line, in any format that can be
understood by `Gfx::Color::from_string`.
This commit gets rid of hard coded file handlers in Launcher.cpp in
favor of using values in the LaunchServer.ini config file.
The previous commit adds checks for the existence of handler programs
while registering handlers. This commit takes advantage of that and
ensures that LaunchServer will not attempt to open a file with a
nonexistent program and can properly report failure before spawning a
new child process.
Resolves#8120
This adds checks in load_handlers() and load_config() to see if the
programs specified in the config files exist before registering them as
handlers.
Resolves#8121
`wasm-as` will do some semantic analysis on the modules, which is not
something we're looking for here.
Instead, use `wat2wasm` to generate the exact module.
The `File::can_write` mechanism lets us check that writes won't block,
meaning some bytes can be immediately written to the underlying device.
This means calling `File::write` in a situation where no data could be
written is a logic error, which we `VERIFY()` in `Process::do_write()`.
TTY, in particular, processes the write in 256-byte buffered chunks.
Previously, we would assert that none of these sub-writes returned zero.
This was a logic error, as this rejected some successful writes. For
example, if there was exactly enough free space in `SlavePty`'s internal
buffer for the previous sub-write to complete fully. This made it
impossible to perform writes larger than `SlavePty`'s internal buffer.
Note that it's not an issue if `on_tty_write` returns zero, as partial
writes are handled correctly by the `buffer.read_buffered` helper. We
won't spin in a loop trying to write to a full buffer.
Fixes#8090
Previously, copying a file to a directory, like this:
```cp README.md Desktop```
correctly copied it to Desktop/README.md, but would fail if the
source was also a directory, for example:
```cp -R Documents Desktop```
Now, that correctly copies it to Desktop/Documents, as you would
expect. :^)
If a window which has an active modal window is focused, the modal
window starts blinking. In this case, the window (and modal) should
still be focused. For this, the order of the checks in
process_mouse_event_for_window has to be changed.
This fixes#8183.
This commit addresses two issues:
1. If you play a 96 KHz Wave file, the slider position is incorrect,
because it is assumed all files are 44.1 KHz.
2. For high-bitrate files, there are audio dropouts due to not
buffering enough audio data.
Issue 1 is addressed by scaling the number of played samples by the
ratio between the source and destination sample rates.
Issue 2 is addressed by buffering a certain number of milliseconds
worth of audio data (instead of a fixed number of bytes).
This makes the the buffer size independent of the source sample rate.
Some of the code is redesigned to be simpler. The code that did the
book-keeping of which buffers need to be loaded and which have been
already played has been removed. Instead, we enqueue a new buffer based
on a low watermark of samples remaining in the audio server queue.
Other small fixes include:
1. Disable the stop button when playback is finished.
2. Remove hard-coded instances of 44100.
3. Update the GUI every 50 ms (was 100), which improves visualizations.
When using `aplay` to play audio files with a sample rate of 96000,
there were occasional one-second gaps in playback. This is
because the Audio::ClientConnection sleeps for a full second when
the audio buffer is full.
One second is too long to sleep, especially for high-bitrate files.
Changing the sleep to a more reasonable value like 100 ms ensures
we attempt to enqueue again before the audio buffer runs empty.
Prior code in `WavLoader::get_more_samples()` would attempt to
read the requested number of samples without actually checking
whether that many samples were remaining in the stream.
This was the cause of an audible pop at the end of a track, due
to reading non-audio data that is sometimes at the end of a Wave file.
Now we only attempt to read up to the end of sample data, but no
further.
Also, added comments to clarify the meaning of "sample", and how it
should be independent of the number of channels.
