If a receiver is given, e.g. via Reflect.get/set(), forward it to the
target object's get()/put() or use it as last argument of the trap
function. The default value is the Proxy object itself.
Previously GUI::Actions which were constructed without initializing
m_shortcut could be activated via an invalid GUI::Shortcut.
Steps to reproduce:
It was possible to enable TextEditor's markdown preview by pressing
Ctrl or Alt (Cmd/Ctrl) keys, which should not happen, as this Action
did not specify a shortcut.
This fix should apply to all other cases where actions where declared
without specifying a shortcut.
It is now possible to use the special IPC::File type in message arguments. In
C++, the type is nothing more than a wrapper over a file descriptor. But when
serializing/deserializing IPC::File arguments, LibIPC will use the sendfd/recvfd
kernel APIs instead of sending the integer inline.
This makes it quite convenient to pass files over IPC, and will allow us to
significantly tighten sandboxes in the future :^)
Closes https://github.com/SerenityOS/serenity/issues/3643
Passing in a plain Value and expecting it to be a native property is
error prone, let's use a more narrow type and pass a NativeProperty
reference directly.
Specification: https://dom.spec.whatwg.org/#concept-event-dispatch
This also introduces shadow roots due to it being a requirement of
the event dispatcher.
However, it does not introduce the full shadow DOM, that can be
left for future work.
This changes some event dispatches which require certain attributes
to be initialised to a value.
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!)
This is a first (huge) step towards modernizing the layout architecture
and bringing it closer to spec language.
Layout is now performed by a stack of formatting contexts, operating on
the box tree (or layout tree, if you will.)
There are currently three types of formatting context:
- BlockFormattingContext (BFC)
- InlineFormattingContext (IFC)
- TableFormattingContext (TFC)
Document::layout() creates the initial BlockFormattingContext (BFC)
which lays out the initial containing block (ICB), and then we recurse
through the tree, creating BFC, IFC or TFC as appropriate and handing
over control at the context boundaries.
The majority of this patch is just refactoring the old logic spread out
in LayoutBlock and LayoutTableRowGroup, and turning into these context
classes instead. A lot more cleanup will be needed.
There are many architectural wins here, the main one being that layout
is no longer performed by boxes themselves, which gives us much greater
flexibility in the outer/inner layout of a given box.
When clicking empty space (beneath any used lines) in the TextEditor,
the cursor would jump to the start of the last line, rather than the
correct column, or the end of the line where appropriate. This was
because in the for_each_visual_line callback would return
IterationDecision::Continue if the clicked point wasn't in the line's
rect. Thus the callback would continue on each iteration and at the
end, would set the cursor to the default column of 0. To fix this I
added a bool to the callback's signature which tells the callback if
the for_each_visual_line method is on the last visual line. The
callback now does not return IterationDecision:Continue if
for_each_visual_line method is on the last line and the correct column
is then calculated with the line passed.
This work is already done (and more correctly) by the parent class
(AbstractView) if we just let it take care of the event instead.
Fixes the root cause of #4096.
Switch over to gamma-aware interpolation. This causes color gradients
to not look so dark in the middle. SIMD optimized code is provided for
sse1 enabled builds.
Fixes#1342.
This doesn't fix all the issues found by the fuzzer, but it fixes
many of them. When running this
Meta/Lagom/Fuzzers/FuzzJPGLoader -jobs=24 -workers=24 \
../Base/res/html/misc/jpgsuite_files/
for 10 minutes on my machine, the fuzzer foudn 2 crashers, but after
this change it finds just ... 2. But with different stacks!
This just fixes ASSERT()s, so it's not security critical, but
ASSERT()s still crash the programs decoding JPGs, and crashing
less is nice even if it's not a security concern.
This patch shrinks X86::Instruction from 56 to 28 bytes by packing data
members more tightly and removing some entirely.
There is still some data duplication between Instruction and the
corresponding InstructionDescriptor but it will be a bit tricky to get
much more out of it.
This looks like a 1-2% improvement on general emulation speed. :^)
This adds a few macros used to determine the category of a floating
point number. This fixes a build error with the jq port due to the
previously missing isnormal() macro.

This moves file extension to icon mappings from compile time macros to an
INI config file (/etc/FileIconProvider.ini), so file icons can easily be
customized and extended :^)
I also switched the format from a static file extension (".foo") to
glob-like patterns ("*.foo", using StringUtils::matches()), which allows
us to assign icons to specific exactly matching file names, like many
IDEs do - e.g. "CMakeLists.txt" or ".prettierrc".
When we hit the last token, make the saved pointer point to the null
terminator instead of to the next token. This ensures that the next
call to strtok_r() returns null as expected.
Found by running GCC in UE. :^)
