Makes the Audio applet, Taskbar clock, CommandPalette, EmojiPicker,
and Assistant work as Popup windows. Popups are frameless, unmovable,
and unresizable by default, in addition to their preemptive function.
Also sets Assistant not to obey widget min size so its search result
area resizes correctly
and the CaptureInput mode. They are a source of unneeded complexity
in WindowServer and have proven prone to regressions, so this patch
replaces them with a simple input preemption scheme using Popups.
Popup windows now have ergonomics similar to menus: When open,
a popup preempts all mouse and key events for the entire window
stack; however, they are fragile and will close after WindowServer
swallows the first event outside them. This is similar to how combo
box windows and popups work in the classic Windows DE and has the
added benefit of letting the user click anywhere to dismiss a popup
without having to worry about unwanted interactions with other
widgets.
with WindowInput{Preempted,Restored} Events and allow Widgets to save
the state of their focus preemption. As of now, only Popups will
preempt input and trigger these events.
For flate and lzw filters, the data can be transformed by this
predictor function to make it compress better. For us this means that
we have to undo this step in order to get the right result.
Although this feature is meant for images, I found at least a few
documents that use it all over the place, making this step very
important.
We previously compared two unrelated values to determine if we parsed
the xref table to completion. We now check if we added every subsection
instead, and double check to make sure we never read past the end.
This filter basically tells us that we are dealing with a JPEG.
Note that by serializing the resulting image we assume that this filter
is the last one in the chain, everything else would be highly unlikely.
We currently don't support ICC color spaces and fall back to a "simple"
one instead.
If no alternative is specified however, we are allowed to pick the
closest match based on the number of color components.
This fixes an issue where we would show an error message on every
subsequent paint event, making it impossible to close or use the
application further.
Some more architectural work is needed if we want to invalidate the
sidebar entries as well.
And TRY early during initialization in FontEditor to leave the app
in a valid state on error. Fixes OOM crashes when cloning the original
font for highlight modifications.
Like other apps, FontEditor now organizes widget visibility toggles
under a View->Layout submenu. The main toolbar and the status bar
can now be turned on and off.
Each GenericInterruptHandler now tracks the number of calls that each
CPU has serviced.
This takes care of a FIXME in the /sys/kernel/interrupts generator.
Also, the lsirq command line tool now displays per-CPU call counts.
These lambdas were marked mutable as they captured a Ptr wrapper
class by value, which then only returned const-qualified references
to the value they point from the previous const pointer operators.
Nothing is actually mutating in the lambdas state here, and now
that the Ptr operators don't add extra const qualifiers these
can be removed.
Even if the pointer value is const, the value they point to is not
necessarily const, so these functions should not add the qualifier.
This also removes the redundant non-const implementations of these
operators.
These functions are now implemented in terms of getpwent_r() which
allows us to remove two FIXMEs about global variable shenanigans.
I'm also adding tests for both APIs. :^)
This gives much better visual results than painting the path directly.
It also has the nice side effect that Type 1 fonts will now look much
more similar to TrueType fonts, which use the same class :^)
In addition, we can now cache glyph bitmaps for repeated use.
The custom TTF path rasterizer is actually generic enough for it to be
used for other fonts. To make this more clear, it now lives on its own
in the "Font" directory.
Registers the PreviewWidget for addition directly into GML. Fixes
its previous double Frame borders. Also standardizes the Apply and
Reset buttons as DialogButtons and spaces them consistently with
other apps. Gives the TabWidget some tasteful container margins.
Right now only the accessibility menu is shared across apps but
it's a good bit of boilerplate that can be consolidated and will
make adding ColorBlindnessFilters to other widgets trivial.
Still some TODOs here:
* We don't handle all capabilities (e.g. proxy)
* We don't match the capabilities against the running browser
But this will parse the capabilities JSON object received from the
WebDriver client.
The spec's text is pretty awkward here, but the way we've currently
transcribed it to C++ means we reject valid script timeouts. This meant
the following would fail:
TimeoutsConfiguration config {}; // Default values.
auto json = timeouts_object(config);
config = TRY(json_deserialize_as_a_timeouts_configuration(json));
Since ff2f31b LibWeb has segfaulted when clicking on links, as the
browsing context (a GCPtr) in the lambda was captured by reference
and was out of scope by the time the callback fired.
Before this could give the `must be followed by in` error before the
undeclared private identifier error. Fixing the `in` error would not
have resolved the other error so this order makes the errors more
actionable.
If we don't check that a private identifier is valid this can break the
assumption that we have a private environment when evaluation the
private identifier. Also an unknown private identifier this should
be a SyntaxError.
This is only visible with something like `Object.getOwnPropertyNames` on
the global object. All other declaration instantiations put the
functions on an environment making the order invisible.
Note that spec order is not quite tree order as in non-strict mode
functions which get hoisted out of blocks appear before top level
functions.

Before putting `throw 1;` in a test file did not fail the file, and it
ignored the rest of the file. Now we check the resulting completion from
run and fail if that is an error.
The way in which dialogs should be handled is configurable by the driver
capabilities object, which we don't support yet. So this implements just
the default mode to dismiss the dialog and return an error if there is
one open.
In the OOPWV, this means we need to refer to the dialog after it has
been open, so we now hold a pointer to whatever dialog is open.
This will be needed for WebDriver, which will require constructing and
controlling dialogs manually. Currently, InputBox will only set its text
value when the OK button is pressed. This changes InputBox to update its
text when done(ExecResult::OK) is invoked in any way.
This also makes the text_value() method public, allows for setting the
text value, and allows for moving-in the initial text value.
Currently, the WebContent process is completely blocked while waiting
for a response to a dialog request. This patch allows the IPC event loop
to continue executing while only blocking the HTML event loop.
This will allow other processes like WebDriver to continue to operate on
the WebContent process while a dialog is open.
We now layout foreign objects as if they form a nested block formatting
context. This probably isn't the most correct way to do this, but it's
a start.
This fixes an error when using auto-fit with grid-gap, as previously
were not taking into account the fact that more columns had been added
to the grid yet the occupation grid had not grown.
Previously were incorrectly initializing the grid gap tracks as were
using the GridSize float constructor, which creates a flexible length.
What is actually wanted is a fixed-size track of a certain size,
indicated in pixels.
This patch optimizes the drawing of aa-lines by rotating the drawn
rectangle to the direction where the line points. That enables us to
draw non-straight lines with the proper width.
If a aa-line is drawn that is infact a straigt line we now dont plot
those lines with multipe rectangles across the line - insted we draw
straight lines in one go with just one rectangle of proper size.
Stroking of lines has been enhanced to take care of the edges between
two lines with drawing the stroke till the intersections of two
connected lines.
This patch changes the initialization of the fill_color of an SVGContext
to transparent instead of black to not draw a black filling if the
elements fill_color is defined as "none".
Since handling overflow: hidden in PaintableBox::before_children_paint
while following paint traversal order can't result in correctly computed
clip rectangle for elements that create their own stacking context
(because before_children_paint is called only for parent but overflow:
hidden can be set somewhere deeper but not in direct ancestor), here
introduced new function PaintableBox::clip_rect() that computes clip
rectangle by looking into containing block.
should_clip_overflow flag that disables clip for absolutely positioned
elements in before_children_paint and after_children_paint is removed
because after changing clip rectangle to be computed from not parent
but containing block it is not needed anymore (absolutely positioned
item is clipped if it's containing block has hidden overflow)
This implementation is some-what complete, with the most common missing
/broken feature being opening pages in new tabs using the "_blank"
target.
This is currently broken due to 2 reasons:
- We currently always claim the Window does not have transient
activation, as we do not track the transient activation timestamp
yet. This means that all such window.open calls are detected as
pop-ups, and as such they are blocked. This can be easily bypassed
by unchecking the 'Block Pop-ups' checkbox in the debug menu.
- There is currently no mechanism for the WebContent process to
request a new tab to be created by the Browser process, and as
such the call to BrowsingContext::choose_a_browsing_context does not
actually open another tab.
In order to avoid the base encode/decode methods from being used (and
failing a static assertion), we must be sure to declare/define the
custom type implementations as template specializations.
After this, LibIPC is no longer sensitive to include order.
For the most part, we try to provide specializations of these functions
in various headers by including "LibIPC/Forward.h" and then declaring
encode() and decode() specializations. However, without any forward
declaration of these types, we aren't actually specializing anything.
Rather, we are just declaring overloads, which trips up the base encode
and decode template definitions.
The result is that LibIPC is very sensitive to include order, and the
DependentFalse<> static assertion would fail if the includes weren't
perfectly ordered.
By properly forward declaring these templates, we can make sure the
specializations receive precedence over the base templates.
This has to get quite messy because we currently do evaluation to value
and reference separately meaning we have to deal with a lot of edge
cases here.
Before this change we would ignore that the second backslash is escaped
and template strings ending with ` \\` would be unterminated as the
second slash was used to escape the closing quote.
This moves Get Window Handle, Close Window, and Get Window Handles over
to WebContent so they may be implemented closer to the spec and be used
by Ladybird.
This hasn't been an issue on Serenity, but on Linux, if a program opens
a TCPServer on some port and then exits, that program can't be re-run
until the OS makes the port available again. This is usually ~2x the TCP
socket's maximum segment lifetime, upwards of a minute.
Add an option to TCPServer to allow re-using the port after the program
exits.
Prevent media query parser from falling back into
MediaQuery::create_not_all() for queries with unknown media type.
With this change following test works correctly:
http://wpt.live/css/css-conditional/at-media-001.html
Previously, all keydown KeyEvents were accepted, causing parent widgets
not to receive them. With the addition of shortcut handling to keydown,
shortcuts were not called when the ImageEditor was focused.
If an app file has RequiresRoot=true, launch the app with the requsite
setuid binary. For GUI apps, this is Escalator. For app files with
RunInTerminal=true, this is pls.
VideoPlayerWidget was keeping a reference to PlaybackManager when
changing files, so the old and new managers would both send frames to
be presented at the same time, causing it to flicker back and forth
between the two videos. However, PlaybackManager no longer relies on
event bubbling to pass events to its parent. By changing it to send
events directly to an Object, it can avoid being ref counted, so that
it will get destroyed with its containing object and stop sending
events.
When the visualization is set to "Album Cover", the player will now try
to load the embedded image. On failure, it defaults to a "Cover" image
file in the directory.
In Player::play_file_path, file_name_changed now needs to be executed
after that the loader have been set, to get the correct image.
This table seems to only exist for OpenType compatibility. There are
some font files, including most embedded fonts in PDF documents, that
don't include one.
For those cases, we now just zero-initialize one to the largest
supported size.
This patch will switch cursor to DragCopy when a user enters a widget
while dragging file(s), giving them a visual clue that it *might* be
dropped into this widget.
This is a rather naive approach, as the cursor icon will change for any
kind of file, as currently programs don't know the drag contents before
dropping it. But after all I think it's better than nothing. :^)
This fixes a scenario in which the active tool can get out of sync in
regards to what it believes it the current ImageEditor. In the case
where multiple images are open, switching between the editor tabs with a
tool selected can lead to this unsynchronized state due to a check that
the ImageEditor's active tool matches the current tool. If this is the
case the method returns early before we properly set the new editor
pointer on the active tool.
Therefore, we don't rely on LibDSP Processors to use allocation guards
themselves. It also demonstrates that nested allocation guards work
correctly :^)
Success responses are meant to be wrapped in a JSON object with a single
"value" key. Instead of doing this in both WebContent and WebDriver, do
it once in LibWeb.
This moves communication and route matching for WebDriver endpoints into
LibWeb. This is to reduce the amount of duplication required to create a
WebDriver implementation for Ladybird.
In doing so, this introduces some cleanup of WebDriver handling. Routes
are now a compile-time array, and matching a route is nearly free of
allocations (we still allocate a Vector for parsed parameters). This
implementation also makes heavier use of TRY semantics to propagate
errors into one handler.
We are expected to return the list of open handles after closing the
current handle. Also just return a WebDriver::Response instead of a
wrapped Error variant.
With the addition of this struct, both the bool to determine if coefs
should be parsed and the token parse itself can take specific
parameters.
This is the last step in parameterizing all the tree parsing, so the
old functions in TreeParser are now unused. This patch is very
satisfying :^)
There's still more work to be done to clean up how the parameters are
passed from Parser, but that's work for another day.
Since these two types are often passed around as a pair, it's easier to
handle them with a simple pair struct, at least for now. Once things
are fully being passed around as parameters wherever possible, it may
be good to change this type for something more generalized.
This adds a tree-parsing function that can be called statically from
specific trees' implementations in TreeParser, of which Partition is
the first. This way, all calls to tree parses will take the context
they need to be able to select a tree and probabilities, which will
allow removal of the state dependence in TreeParser on fields from
itself and Parser.
The two different mode sets are stored in single fields, and the
underlying values didn't overlap, so there was no reason to keep them
separate.
The enum is now an enum class as well, to enforce that almost all uses
of the enum are named. The only case where underlying values are used
is in lookup tables, but it may be worth abstracting that as well to
make array bounds more clear.
Frames will now be queued for retrieval by the user of the decoder.
When the end of the current queue is reached, a DecoderError of
category NeedsMoreInput will be emitted, allowing the caller to react
by displaying what was previously retrieved for sending more samples.
This was changed with a recent move to MutexLocker, but the exact
previous behavior is safer as it holds the lock for the minimum amount
of time in both locations. We don't want to introduce these kinds of
subtle bugs.
If this is not done, the event loop pointer will be initialized to
exploded MALLOC_SCRUB_BYTEs and the null pointer check at destruction
time will fail, causing a crash any time an audio client without a
started enqueuer thread exits. With this change, we correctly skip
quitting the event loop both when it was never started (if the enqueuer
thread never ran) as well as if it already exited (if the enqueuer
thread exited fast enough) without additional logic for the two very
different cases.
The buffer provided to `OutputMemoryStream` was made a private class
member. This is because there is no reason to re-create it in every
iteration. Also, the logic becomes more symmetric with
`m_zero_filled_buffer` which is already a class member.
Initialize the `AudioServer::Mixer::m_zero_filled_buffer` to zero. The
garbage memory inside that buffer was causing a glitch sound when the
user was toggling the mute checkbox or was moving the volume slider on
and off zero. Glitching was more obvious if the toggling was happening
without any sound being played in parallel.
In addition to that, the `m_zero_filled_buffer` turned to `const` since
there is no intention to modify its content.
WebDriver now only has an IPC connection to WebContent. WebDriver still
launches the browser, but now when the session ends, we simply send a
SIGTERM signal to the browser.
There are a couple changes here from the existing Get All Cookies
implementation.
1. Previously, WebDriver actually returned *all* cookies in the cookie
jar. The spec dictates that we only return cookies that match the
document's URL. Specifically, it calls out that we must run just the
first step of RFC 6265 section 5.4 to perform domain matching.
This change adds a special mode to our implementation of that section
to skip the remaining steps.
2. We now fill in the SameSite cookie attribute when serializing the
cookie to JSON (this was a trival FIXME that didn't get picked up
when SameSite was implemented).
This means that rather than this:
```
AK_TYPEDEF_DISTINCT_NUMERIC_GENERAL(u64, true, true, false, false,
false, true, FunctionAddress);
```
We now have this:
```
AK_TYPEDEF_DISTINCT_NUMERIC_GENERAL(u64, FunctionAddress, Arithmetic,
Comparison, Increment);
```
Which is a lot more readable. :^)

This patch adds a special EnvironmentCoordinate::global_marker value
that signifies that a binding lookup ended up searching the global
environment. It doesn't matter if we find it there or not, the global
marker is always returned. This allows us to bypass other environments
on subsequent access, going directly to the global environment.
Instead of offsetting the screenshot by the position of the document
element, just take a screenshot of the entire content rect. After
looking at Acid3 a bit more, this more accurately represents what the
user actually sees on the webpage.
This will allow for implementing the screenshot action closer to the
spec, as we can now use HTMLCanvasElement to encode the bitmap, and
capture the screenshot on the animation frame loop.
