This syscall allows a parent process to disown a child process, setting
its parent PID to 0.
Unparented processes are automatically reaped by the kernel upon exit,
and no sys$waitid() is required. This will make it much nicer to do
spawn-and-forget which is common in the GUI environment.
Change #2811 made window title stripes and window title shadow themable,
but it used the same stripe and shadow color for all window modes.
This is fine for the new 'basalt' theme which uses the same color
in all four window modes, but it changed the default theme so that
background windows had brown stripes and a brown shadow.
Instead, make the title stripe and title shadow themable per window mode,
and change the default theme to restore the colors it had before
change #2811: The title stripe color is the same as Border1 for all
window modes, and the title shadow is the same as the title stripe
darkened by 0.6.
Adds a classic volume slider to the AudioApplet. Percent text
and mute state can now be toggled via checkboxes. Left click opens,
right click mutes. Updates existing icons and adds unique icons for
muted vs zero volume states.
This allows you to not have to write a separate test file
for the same thing but in a different situation.
This doesn't handle when you change the page with location.href
however.
Changes the name of the page load handlers to prevent confusion
with this.
Accentuated letters and other characters from the Unicode Block
"Latin-1 Supplement" were added; they weren't supported in the past.
Regarding the numpad: there was a `"", ` too much in the keymap, which
was shifting the keys when pressed (e.g. I would get a '9' instead of a '+')
LibWeb currently has no test suite or program. Let's change that :^)
test-web is mostly a copy of test-js, but modified for LibWeb.
test-web imports both LibJS/Tests/test-common.js and
LibWeb/Test/test-common.js
LibWeb's suite provides the ability to specify the page to load,
what to do before the page is loaded, and what to do after it's
loaded.
This also provides a test of document.doctype and its close sibling
document.compatMode.
Currently, this isn't added to Lagom because of CodeGenerators.
The Audio applet now dislays the main mix volume next to the speaker
icon. A click on the applet still mutes the global mixer. By scrolling
the mouse wheel while on the applet, you can decrease/increase the mixer
volume. Different icons will be painted depending on the volume and the
mute state.
Happy listening :^)
The theming system can now control title bar height, title button
size, title stripe color and the title text shadow color.
The implemented theme metrics system could be later extended to LibGUI
to allow themes to change widget padding, border width, etc.
'W' doesn't have to go up to the edges which makes 'WWW'
look better, and it imho looks fine in other contexts too.
Update 'w' to match.
Don't change Katica since it has enough room for the current W.
In all default fonts, make the lower bar of the F one pixel shorter to
match the middle bare of the E.
Make the W in CsillaThin a bit shorter on the sides and make it
go less high in the middle. This makes it look more like the W in
CsillaBold, makes the middle high spot in W match the height of
the same spot in X Y E F H. Making it shorter on the side makes
the letter look better when its next ot other full-width letters,
e.g. in "WWW".
Make the w in Katica10 match new new W in CsillaThin. The bold
letters already match, and in general it looks like Csilla is
a monospace version of Katica.
This introduces a new X86 CPU emulator for running SerenityOS userspace
programs in a virtualized interpreter environment.
The main goal is to be able to instrument memory accesses and catch
interesting bugs that are very hard to find otherwise. But before we
can do fancy things like that, we have to build a competent emulator
able to actually run programs.
This initial version is able to run a very small program that makes
some tiny syscalls, but nothing more.
This adds a new 32x32 Help application icon, a new open book icon,
copies the current book icon as Help's 16x16 icon, and updates
the Help application file to reflect these changes.
Now that we have a standalone test-js program, the "-t" test mode of the
js REPL is unused and can simply be removed. Required functionality has
been duplicated in test-js (isStrictMode function, loading of testing
utilities).
Also remove outdated information about tests from the js(1) man page.
Everyone who connects to ProtocolServer now gets his own instance.
This means that different users can no longer talk to the same exact
ProtocolServer process, enhanching security and stability.
This patch adds support for JPEG decoding. The JPEG decoder is capable
of handling standard 2x1 horizontal, 2x1 vertical and quartered chroma
subsampling. The implemented Inverse DCT performs with a decent speed.
As of interchange formats, since we tend to ignore the metadata in APPn
markers, the decoder can handle any format compatible with JFIF, which
includes EXIFs and sometimes WebMs too. The decoder does not support
progressive JPEGs yet.
The new ImageDecoder service (available for members of "image" via
/tmp/portal/image) allows you to decode images in a separate process.
This will allow programs to confidently load untrusted images, since
the bulk of the security concerns are sandboxed to a separate process.
The only API right now is a synchronous IPC DecodeImage() call that
takes a shbuf with encoded image data and returns a shared buffer and
metadata for the decoded image.
It also comes with a very simple library for interfacing with the
ImageDecoder service: LibImageDecoderClient. The name is a bit of a
mouthful but I guess we can rename it later if we think of something
nicer to call it.
There's obviously a bit of overhead to spawning a separate process
for every image decode, so this is mostly only appropriate for
untrusted images (e.g stuff downloaded from the web) and not necessary
for trusted local images (e.g stuff in /res)
Port the WebContent service to the new MultiInstance mechanism that
Sergey added. This means that every new WebContentView gets its very
own segregated WebContent process.
The "WebContent" service provides a very restricted instance of LibWeb
running as an unprivileged user account. This will be used to implement
process separation in Browser, among other things.
This first cut of the service only spawns a single WebContent process
when someone connects to /tmp/portal/webcontent. We will soon switch
this over to spawning a new process for each connection.
Since this feature is very immature, we'll be bringing it up inside of
Demos/WebView as a separate demo program. Eventually this will become
a reusable widget that anyone can embed and easily get out-of-process
web content in their GUI.
This is pretty, pretty cool! :^)
We were getting a little overly memey in some places, so let's scale
things back to business-casual.
Informal language is fine in comments, commits and debug logs,
but let's keep the runtime nice and presentable. :^)
I booted the system on a much better screen than the one I normally use
and the variance in contrast between different icons bothered me.
Here's an attempt to fix that, while also redoing some icons that I've
wanted to redo for a while. :^)
Absolutely positioned blocks now register themselves with their
containing block (and note that the containing block of an absolutely
positioned box is the nearest non-statically positioned block ancestor
or the ICB as fallback.)
Containing blocks then drive the layout of their tracked absolutely
positioned descendants as a separate layout pass.
This is very far from perfect but the general direction seems good.
This patch introduces a bunch of things:
- Subframes (Web::Frame::create_subframe())
- HTMLIFrameElement (loads and owns the hosted Web::Frame)
- LayoutFrame (layout and rendering of the hosted frame)
There's still a huge number of things missing, like scrolling, overflow
handling, event handling, scripting, etc. But we can make a little
iframe in a document and it actually renders another document there.
I think that's pretty cool! :^)
This patch adds ImageResource as a subclass of Resource. This new class
also keeps a Gfx::ImageDecoder so that we can share decoded bitmaps
between all clients of an image resource inside LibWeb.
With this, we now share both encoded and decoded data for images. :^)
I had to change how the purgeable-volatile flag is updated to keep the
volatile-images-outside-the-visible-viewport optimization working.
HTMLImageElement now inherits from ImageResourceClient (a subclass of
ResourceClient with additional image-specific stuff) and informs its
ImageResource about whether it's inside the viewport or outside.
This is pretty awesome! :^)
This patch adds a context menu to variables in the debugger variable
tree view that has an option to set the value of a variable. An input
box will pop up asking for the new value of the variable, which
is then parsed and used to set the actual variable.
Now that we have SystemServer that can (re)spawn the Shell, we don't need a
separate server just for that.
The two shells (on tty0 and tty1) are configured to only be started when booting
in text mode. This means you can now simply say boot_mode=text on the kernel
command line, and SystemServer will set up the system and spawn a comfy root
shell for you :^)
We can now parse a little DOM like this:
<!DOCTYPE html>
<html>
<head></head>
<body>
<div></div>
</body>
</html>
This is pretty slow work, but the incremental progress is satisfying!
When hit testing encountered a block with inline children, we assumed
that the inline children are nothing but text boxes. An inline-block
box is actually a block child of a block with inline children, so we
have to handle that scenario as well. :^)
Fixes#2353.
In order to actually view the web as it is, we're gonna need a proper
HTML parser. So let's build one!
This patch introduces the Web::HTMLTokenizer class, which currently
operates on a StringView input stream where it fetches (ASCII only atm)
codepoints and tokenizes acccording to the HTML spec tokenization algo.
The tokenizer state machine looks a bit weird but is written in a way
that tries to mimic the spec as closely as possible, in order to make
development easier and bugs less likely.
This initial version is far from finished, but it can parse a trivial
document with a DOCTYPE and open/close tags. :^)
Adds metadata about apps for what file types and protocols they can
handle, then consumes that in the LaunchServer. The LaunchServer can
then use that to offer multiple options for what apps can open a given
URL. Callers can then pass back the handler name to the LaunchServer to
use an alternate app :)
This is not simply an inversion of the Slightly Smiling Face emoji.
The facial features were flipped vertically but the underlying "face"
was kept the same, because for both emojis the top is lighter than the
bottom.
It will listen for clipboard content changes in the backgroud. Once you click
on its icon, it will pop up a window listing all recorded clipboard contents.
You can then double-click on an item to copy it again.
This commit moves the clipboard from WindowServer into a new Clipboard
service program. Clipboard runs as the unprivileged "clipboard" user
and with a much tighter pledge than WindowServer.
To keep things working as before, all GUI::Application users now make
a connection to Clipboard after making the connection to WindowServer.
It could be interesting to connect to Clipboard on demand, but right
now that would necessitate expanding every GUI app's pledge to include
"unix" and also unveiling the clipboard portal, which I prefer not to.
Many properties can now have percentage values that get resolved in
layout. The reference value (what is this a percentage *of*?) differs
per property, so I've added a helper where you provide a reference
value as an added parameter to the existing length_or_fallback().
