These tags are either part of the baseline specification or included by
default by GIMP when exporting TIFF files. Note that we don't add
support for them in the decoder yet. This commit only allows us to parse
the metadata and display it gracefully.
It is implemented in the way identical to how it works in CPU painter:
1. SampleUnderCorners command saves pixels within corners into a
texture.
2. BlitCornerClipping command uses the texture prepared earlier to
restore pixels within corners.
The styling of elements using the `use_pseudo_element()` was only
applied on layout. When an element style was recomputed later that
styling was not overruled with the pseudo element selector styles.
This moves the styling override from `TreeBuilder.cpp` to
`StyleComputer.cpp`. Now the styles are always correctly applied.
I also removed the method `property_id_by_index()` because it was
not needed anymore.
Als some calls to `invalidate_layout()` in the Meter, Progress and
Select elements where not needed anymore because the style values
are update on the changing of the style attribute.
This fixes issue #22278.
Previously, `replace` used `find_all` to find all of the positions to
replace. But `find_all` finds all the *overlapping* instances of the
needle, while `replace` assumed that the next position was always at
least `needle.length()` away from the last one. This led to crashes like
https://github.com/SerenityOS/jakt/issues/1159.
This commit un-deprecates DeprecatedString, and repurposes it as a byte
string.
As the null state has already been removed, there are no other
particularly hairy blockers in repurposing this type as a byte string
(what it _really_ is).
This commit is auto-generated:

This makes using the line editor much nicer when multi-code-point
graphemes are present in the input (e.g. flag emojis, or some cjk
glyphs), and avoids messing up the buffer when deleting text, or
cursoring around.
This commit fixes the odd state after pasting some text containing
multibyte code points.
This also increases the input buffer size, as reading 16 bytes at a time
felt slightly laggy when pasting a large number of emojis :^)
We were doing this synchronously, which was unsafe in that caused us to
re-enter the module map entry setting code while iterating over the
map's entries.
The fix is simply to do what the spec says and queue up a task. This way
the processing gets deferred to a later time.
To avoid stepping into this problem again, I've also added a reentrancy
check in ModuleMap.
This fixes a sporadic crash in HTML::ModuleMap::add() caught by ASAN.
In particular, this was happening regularly on https://shopify.com/
Let's not assume there is one global OpenGL context because it might
change once we will start creating >1 page inside single WebContent
process or contexts for WebGL.
The signal handling code (and possibly other code as well) expects this
struct to have an alignment of 16 bytes, as it pushes this struct on the
stack.
This is similar to "unique" shapes, which were removed in commit
3d92c26445.
The key difference is that dictionary shapes don't have a serial number,
but instead have a "cacheable" flag.
Shapes become dictionaries after 64 transitions have occurred, at which
point no further transitions occur.
As long as properties are only added to a dictionary shape, it remains
cacheable. (Since if we've cached the shape pointer in an IC somewhere,
we know the IC is still valid.)
Deleting a property from a dictionary shape causes it to become an
uncacheable dictionary.
Note that deleting a property from a non-dictionary shape still performs
a delete transition.
This fixes an issue on Discord where Object.freeze() would eventually
OOM us, since they add more than 16000 properties to a single object
before freezing it.
It also yields a 15% speedup on Octane/pdfjs.js :^)
MasterPTY::read called DoubleBuffer::read which takes a mutex (which
may block) while holding m_slave's spinlock. If it did block, and was
later rescheduled on a different physical CPU, we would deadlock on
re-locking m_slave inside the unblock callback. (Since our recursive
spinlock implementation is processor based and not process based)
MasterPTY's double buffer unblock callback would take m_slave's
spinlock and then call evaluate_block_conditions() which would take
BlockerSet's spinlock, while on the other hand, BlockerSet's
add_blocker would take BlockerSet's spinlock, and then call
should_add_blocker, which would call unblock_if_conditions_are_met,
which would then call should_unblock, which will finally call
MasterPTY::can_read() which will take m_slave's spinlock.
Resolve this by moving the call to evaluate_block_conditions() out of
the scope of m_slave's spinlock, as there's no need to hold the lock
while calling it anyways.
With this change, Document now always has a Web::Page. This means we no
longer rely on the breakable link between Document and BrowsingContext
to find a relevant Web::Page.
Fixes#22290
If there's no loadable segments then there can't be any code to execute
either. This resolves a crash these kinds of ELF files would cause from
the directly following VERIFY statement.
Previously we would unintentionally leave them zero-initialized,
resulting in any threads created post fork (but without execve) having
invalid thread local storage pointers stored in their FS register.
Previously, we stored two representations of the same string in
`CompletionSuggestion` object: one for the bytes and the other for the
code points corresponding to those bytes. To minimize duplication, this
patch combine both representations into a single UTF-8 string, which is
already supported by our new String class.
Following this update, we successfully reduce the size of each object
from 376 bytes to 256 bytes
Prior to this commit, it was possible to get a socket stuck in a state
with enqueued entries, waiting for a nonexistent request to finish.
This state could be entered by issuing a request immediately after the
completion of another one, and before deferred_invoke execution in the
event loop.
This commit closes this hole by making sure the socket is never in a
state where it can queue requests without an active job.
A Python script is much easier to maintain than the organically grown
variable mess that was run.sh.
For now, the script inherits most environment variable modifiability
from the shell script, but this is not a requirement.
While porting this script, a couple of improvements have been made:
- Spaces (especially in paths) cannot break most arguments anymore.
Exceptions are environment variables specifying multiple arguments on
purpose, these should be replaced in the future anyways.
- Force control over virtualization is now possible with
SERENITY_VIRTUALIZATION_SUPPORT. If set to 0, this variable was
sometimes ignored before.
- Handling Windows native QEMU is much more robust. Multiple incorrect
checks for WSL, but not Windows native QEMU, were used before. This
would also allow disabling native Windows QEMU much more easily in the
future, which is necessary for GDB.
- Various machine types had wrong or outdated arguments, such as qn.

This patch adds the new DynamicWidgetContainer for the right panel
elements. This allows the user to collapse, expand or even detach
widgets to a separate window. The collapsed or expanded state is
persisted so that they are restored after application startup.
With this change it is possible to shrink the size of widgets to a
minimum in order to give more space to other currently important
widgets.
Add a new widget "DynamicWidgetContainer" that is used to group it's
child widgets within an collapsable and detachable container. The
DynmnicWidgetContainer is able to persist it's view state if a config
domain has been provided. Having that set will allow the widget to
restore it's view state automatically.
