The Qt docs are not that clear, but to get the number of steps the
wheel was scrolled you divide by 120 (which when multiplied by
wheelScrollLines() gives the scroll offset).
This is only possible if listing an entire directory, because the LibC
readdir function will return the raw inode number in each struct dirent,
therefore allowing to print it as well.
Previously we could get a raw pointer to a Mount object which might be
invalid when actually dereferencing it.
To ensure this could not happen, we should just use a callback that will
be used immediately after finding the appropriate Mount entry, while
holding the mount table lock.
We don't really need this method anymore, because we could just try to
find the mount entry based on the given mount point host custody.
This also allows us to remove the is_vfs_root and root_inode_id methods
from the VirtualFileSystem class.
We could easily encounter a case where we do the following:
```
mkdir -p /tmp2
mount /dev/hda /tmp2
```
would produce a bug that doing `ls /tmp2/tmp2` will give the contents
on `/dev/hda` ext2 root directory and also on `/tmp2/tmp2/tmp2` and so
on.
To prevent this, we must compare the current custody against each mount
entry's custody to ensure their paths match.
This is not useful, as we have literally zero knowledge about where this
inode is actually located at with respect to the entire global path tree
so we could easily encounter a case where we do the following:
```
mkdir -p /tmp2
mount /dev/hda /tmp2
```
and when traversing the /tmp2 directory entries, we will see the root
inode of /dev/hda on "/tmp2/tmp2", even if it was not mounted.
Therefore, we should just plainly give the raw directory entries as they
are written "on the disk". Anything else that needs to exactly know if
there's an underlying mounted filesystem, can just use the stat syscall
instead.
This ensures that the host mount point custody path is not the same like
the new to-be-mounted custody.
A scenario that could happen before adding this check is:
```
mkdir -p /tmp2
mount /dev/hda /tmp2/
mount /dev/hda /tmp2/
mount /dev/hda /tmp2/ # this will fail here
```
and after adding this check, the following scenario is now this:
```
mkdir -p /tmp2
mount /dev/hda /tmp2/
mount /dev/hda /tmp2/ # this will fail here
mount /dev/hda /tmp2/ # this will fail here too
```
Add the CanvasTextDrawingStyles mixin with the textAlign and
textBaseline attributes. Update fill_text in CanvasRenderingContext2D
to move the text rect by the text align and text baseline attributes.
Wrote a simple HTML example to showcase the new features.
We were already parsing non-function-syntax :host, so let's also do
the :host(...) variant. Note that we don't have matching for these yet.
This fixes many issues on sites generated by Wix, as they often have
selector lists that include some :host() selector, and we'd reject the
entire rule after failing to parse it.
Documentation says that pixelDelta() is not reliable across platforms
so always using angleDelta() should produce more predictable scrolling
behaviour.
Reactive images that had an image source selected based on viewport
size would only update when the images were first fetched, meaning the
last valid image source would become stuck in an image element. By
implementing the last step for reacting to environment changes, we can
run the proper updates even when the image does not need to be fetched.
This means we no longer show any characters the user types while top
is running.
Disabling line buffering has the same effect as enabling
non-blocking I/O, but it doesn't crash the terminal when we exit the
program without restoring stdin to its original state. This would
previously happen when a SIGKILL signal was received, for example.
This stuff is pretty hairy since the specifications don't give any
guidance on which widths to use when calculating the intrinsic height of
flex items in a column layout.
However, our old behavior of "treat anything indefinite as fit-content"
was definitely not good enough, so this patch improves the situation by
considering values like `min-content`, `max-content` and `fit-content`
separately from `auto`, and making the whole flex layout pipeline aware
of them (in the cross axis context).
`vim` does not use a mechanism like `config.sub` for determining the
canonical system name from the `--target` triple passed to `configure`.
Instead, it directly executes the `uname` executable on the host. This
leads to it trying to build macOS-specific files on Mac hosts even if we
are compiling for a different platform. To make cross-compilation
possible, developers added a way to override `uname`'s output with
environment variables. Let's set these.

Use the max-width of percentage cells instead of min-width as the
reference to be used to compute the total table width. The specification
only suggests that the UA should try to satisfy percentage constraints
and this behavior is more consistent with other browsers.
This loosens the connection to the AST interpreter and will allow us to
generate SourceRanges for the Bytecode interpreter in the future as well
Moves UnrealizedSourceRanges from TracebackFrame to the JS namespace for

This predictor is much more complicated than the others. Indeed, to be
computed, it needs its own value but for other pixels. As you can guess,
implementing it involved the introduction of a structure to hold that
data.
Fundamentally, this predictor uses the value of the error between the
predicted value and the true value (aka decoded value) of pixels around.
One of this computed error (namely max_error) is used as a property, so
this patch also solves a FIXME in `get_properties`.
To ease the access to value that are close in the channel and moving
their values around, this patch adds a `Neighborhood` struct which holds
this data. It has been used in `prediction()` and it allowed to simplify
the signature and to remove the explicit retrieval of the underlying
data.
All this work allows us to decode the default image that appears when
loading `https://jxl-art.surma.technology`. However, we still render it
incorrectly due to the lack of support for orientation values different
from 1.
Rather than directing mouse wheel events to the QAbstractScrollArea,
send them to the WebContent process, allowing it to determine if they
should be consumed by the element or used for page scrolling.
The `gettext` port comprises of multiple libraries, however `libintl.so`
is the one most commonly used in external executables/libraries, so
porting the patches to this one is enough.
Instead, pass our system name to its (non-autotools) configure script.
Tell it to include a SONAME to avoid breaking dependent ports when
updating zlib.
The pretty-print gdb helpers were not updated since the
DeprecatedString change. This commit introduces a new printer for String
and renames the old one to DeprecatedString.
And don't try to do it every time the Help button is clicked.
This fixes a crash when clicking the Help button twice (setting window
mode on an already visible window is not supported).
This also fixes a situation where when opening the Help window with an
action, we didn't set its mode to "Modeless".
Before, if a bareword wasn't a runnable program's filename it got
colored red and white otherwise. Now, additionally it will be checked if
it is a "prefix" of a possible command and colored yellow if it is and
red if not.
Coloring this way provides another "feedback" to the user: If while
typing out a command name the color changes from yellow to red then a
typo occurred :^)
To check if a bareword is a prefix the `Shell::complete_program_name()`
function is utilized (if pressing tab gives you some suggestions then it
is a prefix).
The implementation of this plugin is meant to eventually replace all
current audio plugins in Ladybird. The benefits over the current Qt-
based audio playback plugin in Ladybird are:
- Low latency: With direct access to PulseAudio, we can ask for a
specific latency to output to allow minimal delay when pausing or
seeking a stream.
- Accurate timestamps: The Qt audio playback API does not expose audio
time properly. When we have access directly to PulseAudio APIs, we can
enable their timing interpolation to get an accurate monotonically-
increasing timestamp of the playing audio.
- Resiliency: With more control over how the underlying audio API is
called, we have the power to fix most bugs we might encounter. The
PulseAudio wrappers already avoid some bugs that occur with QAudioSink
when running through WSLg.
This adds an abstract `Audio::PlaybackStream` class to allow cross-
platform audio playback to be done in an opaque manner by applications
in both Serenity and Lagom.
Currently, the only supported audio API is PulseAudio, but a Serenity
implementation should be added shortly as well.
Since the existing Promise class is designed with deferred tasks on the
main thread only, we need a new class that will ensure we can handle
promises that are resolved/rejected off the main thread.
This new class ensures that the callbacks are only called on the same
thread that the promise is fulfilled from. If the callbacks are not set
before the thread tries to fulfill the promise, it will spin until they
are so that they will run on that thread.
Previously, a QTimer was used to start processing of our event queue in
the main Qt event loop. Unfortunately, QTimers are not thread-safe, and
disallow starting of a timer from a different thread than it was
created in.
Instead, use a dummy QObject to post a custom QEvent to the main loop
from whatever thread we like, and process our event queue when it is
received by our dummy object.
The logic for `EventLoopImplementationQt::pump()` caused calls to
`EventLoop::pump(PumpMode::DontWaitForEvents)` to not consume events
posted to the Qt event queue. This caused the window to be unresponsive
even when polling the event loop, if waiting was not desired.
