This is needed so we can receive file descriptors from ProtocolServer.
Fixes #4660.
|
|
This patchset makes ProtocolServer stream the downloads to its client
(LibProtocol), and as such changes the download API; a possible
download lifecycle could be as such:
notation = client->server:'>', server->client:'<', pipe activity:'*'
```
> StartDownload(GET, url, headers, {})
< Response(0, fd 8)
* {data, 1024b}
< HeadersBecameAvailable(0, response_headers, 200)
< DownloadProgress(0, 4K, 1024)
* {data, 1024b}
* {data, 1024b}
< DownloadProgress(0, 4K, 2048)
* {data, 1024b}
< DownloadProgress(0, 4K, 1024)
< DownloadFinished(0, true, 4K)
```
Since managing the received file descriptor is a pain, LibProtocol
implements `Download::stream_into(OutputStream)`, which can be used to
stream the download into any given output stream (be it a file, or
memory, or writing stuff with a delay, etc.).
Also, as some of the users of this API require all the downloaded data
upfront, LibProtocol also implements `set_should_buffer_all_input()`,
which causes the download instance to buffer all the data until the
download is complete, and to call the `on_buffered_download_finish`
hook.

These include the mouse acceleration factor and the scroll length
step size.
|

The settings are also saved to the config file to survive reboots.

This patch removes size policies and preferred sizes, and replaces them
with min-size and max-size for each widget.
Box layout now works in 3 passes:
1) Set all items (widgets/spacers) to their min-size
2) Distribute remaining space evenly, respecting max-size
3) Place widgets one after the other, adding spacing in between
I've also added convenience helpers for setting a fixed size (which is
the same as setting min-size and max-size to the same value.)
This significantly reduces the verbosity of widget layout and makes GML
a bit more pleasant to write, too. :^)

This makes them shrink when the taskbar fills with too many buttons.
It doesn't scale to infinity open windows, but it's better than them
escaping off screen after 6 open windows. :^)
|
|
This tells you where the mouse cursor is in screen coordinates.

The compose() function is supposed to be fast since it can execute
60 times per second. Let's not do obviously avoidable things like
configuration value lookups in there. :^)
|
|
This way we can use it instead of icon_for_path() in a bunch of places
and avoid loading the full FileIconProvider configuration.
|
|
This reduces naming confusion when the icons are used for other
use cases that require a triangle shape
|
|
Draw it in a threed style with a little shadow under it.
|
|
This was mentioned in #4574, and the more I think about it the more it
feels just right - let's move it there! :^)
Having to link LaunchServer against LibGUI explicitly should've been
telling enough...

The DevFS along with DevPtsFS give a complete solution for populating
device nodes in /dev. The main purpose of DevFS is to eliminate the
need of device nodes generation when building the system.
Later on, DevFS will assist with exposing disk partition nodes.

clang trunk with -std=c++20 doesn't seem to properly look for an
aggregate initializer here when the type being constructed is a simple
aggregate (e.g. `struct Thing { int a; int b; };`). This template fails
to compile in a usage added 12/16/2020 in `AK/Trie.h`.
Both forms of initialization are supposed to call the
aggregate-initializers but direct-list-initialization delegating to
aggregate initializers is a new addition in c++20 that might not be
implemented yet.

Move the shadow 1 more pixel away from the unhovered icon location,
making a total 2 pixel distance between the icon and the shadow.
Also tweak the shadow color to be a darkened variant of the base color
underneath the icon.

We now have a handy Core::Account class that we can use instead of iterating
over the passwd database ourselves.

"Foo=" should be treated the same as "Foo" being missing.

Browser supports very few protocols (http, https, gemini, file) at the
moment, so there's no point in using it as a catch-all and default
protocol handler. I added an explicit association for gemini to
/bin/Browser instead.
This stops Desktop::Launcher::open() from reporting success for any URL,
which really isn't the case (Browser shows an error page...).

POSIX allows the default streams (stdin, stdout and stderr) to be
macros, which means that on such systems (musl libc is one) building
Lagom will fail due to the File::std*() names.
Also fix any files that use these identifiers.

Problem:
- `(void)` simply casts the expression to void. This is understood to
indicate that it is ignored, but this is really a compiler trick to
get the compiler to not generate a warning.
Solution:
- Use the `[[maybe_unused]]` attribute to indicate the value is unused.
Note:
- Functions taking a `(void)` argument list have also been changed to
`()` because this is not needed and shows up in the same grep
command.

This allows us to get rid of some ByteBuffer::wrap() usage.

This adds the ability to specify cursor attributes as part of their
file names, which allows us to remove hard coded values like the hot
spot from the code. The attributes can be specified between the last
two dots of the file name. Each attribute begins with a character,
followed by one or more digits that specify a uint value.
Supported attributes:
x: The x-coordinate of the cursor hotspot
y: The y-coordinate of the cursor hotspot
f: The number of animated frames horizontally in the image
t: The number of milliseconds per frame
For example, the filename wait.f14t100.png specifies that the image
contains 14 frames that should be cycled through at a rate of 100ms.
The hotspot is not specified, so it defaults to the center.

|
There is now only Document::update_layout().
|
|
Almost everyone using this API actually wanted String instead of a
ByteBuffer anyway, and there were a bunch of slightly different ways
clients would convert to String.
Let's just cut out all the confusion and make it return String. :^)

This isn't entirely symmetrical with on_load_start as it will also fire
on reloads and back/forward navigations. However, it's good enough for
some basic use cases, and we can do more sophisticated notifications
later on when we need them.

This used to crash 'pape -c' on a fresh image. Note that the special value
is '', the empty string, and *not* NULL, i.e. an unset string. An empty
string implies that the wallpaper is not an image, but rather a solid color.
|
|
There isn't always a hovered item, so let's not assume things.
|

The desktop can now be split up into halves (both vertical and
horizontal) and quarters by dragging a window into the corresponding
edge or corner.
This makes tiling behave more like you would expect from similiar
window managers.

Previously, the Mixer class would only check for an added BufferQueue
if the list of active queues was empty. If more than one client
connected to AudioServer, its queue would never be added to the list of
active queues.
This fix adds a flag that, when set, will cause the sound thread to wait
for a new BufferQueue.

Layout was using an outdated viewport rect that we set *after* doing
a layout due to resize. That meant that layout-in-response-to-resize
was always lagging behind the current size of the view.
The root of this problem was how Frame kept both a viewport rect
(with both scroll offset and size) and a frame size. To fix this,
only store the viewport scroll offset, and always use the frame size.
This way they can't get out of sync and the problem goes away. :^)
Fixes #4250.

We need to call waitpid until no more waitable children are available.
This is necessary because SIGCHLD signals may coalesce into one when
multiple children terminate almost simultaneously.
Also, switch to EventLoop's asynchronous signal handling mechanism,
which allows more complex operations in the signal handler.

Bring the names of various boxes closer to spec language. This should
hopefully make things easier to understand and hack on. :^)
Some notable changes:
- LayoutNode -> Layout::Node
- LayoutBox -> Layout::Box
- LayoutBlock -> Layout::BlockBox
- LayoutReplaced -> Layout::ReplacedBox
- LayoutDocument -> Layout::InitialContainingBlockBox
- LayoutText -> Layout::TextNode
- LayoutInline -> Layout::InlineNode
Note that this is not strictly a "box tree" as we also hang inline/text
nodes in the same tree, and they don't generate boxes. (Instead, they
contribute line box fragments to their containing block!)
