Since Core::Object properties are really only used by GML now that the
Inspector is long gone, there's no need for these to pollute
Core::Object.
This patch adds a new GUI::Object class to hold properties, and makes
it the new base class of GUI::Window, GUI::Widget and GUI::Layout.
The "instantiate an object by name" mechanism that GML uses is also
hoisted into GUI::Object as well.
We got some errors while loading https://twinings.co.uk/ about this
interface missing, and it looked fairly simple so I sketched it out.
Note that I did leave some FIXMEs where it's not clear exactly which
metrics we should be returning.
This object is available as `window.internals` (or just `internals`) and
is only accessible while running in "test mode".
This first version only has one API: gc(), which triggers a garbage
collection immediately.
In the future, we can add more APIs here to help us test parts of the
engine that are hard or impossible to reach via public web APIs.
This could happen if a sequence of '0' parts was followed by a longer
sequence of '0' parts at the end of the host. The first sequence was
being used for the compress, and not the second.
For example, [1:1:0:0:1:0:0:0] was being serialized as: [1:1::1:0:0:0]
instead of [1:1:0:0:1::].
Fix this by checking at the end of the loop if we are in the middle of a
sequence of '0' parts that is longer than the current longest.
This changes the default behavior, so that, by default, color codes,
hyperlinks and additional spacing are only emitted when standard
output is connected to a terminal.
The default coloring behavior can be overridden with the `--color`
option. Valid arguments for this option are: 'always', 'never' and
'auto' (default).
Everywhere only ever expects percent encoding to occur, so let's just
remove this flag altogether. At the same time, replace some
DeprecatedString with StringView.
Doing this means we no longer need to maintain our own Doom fork and
we get the newest features of the upstream repository, such as sound
effects and music.
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).
