We don't need to check if a function parameter is already declared
while creating bindings for them because we deduplicate their names by
storing them in a hash table in one of the previous steps.
This change makes React-Redux-TodoMVC test in Speedometer run 2%
faster.
The existing implementation has some pre-existing issues where it is
incorrectly assumes that byte offsets are given through the IDL instead
of UTF-16 code units. While making these changes, leave some FIXMEs for
that.
This is required in porting over CharacterData from DeprecatedString to
String.
Unfortunately, as with ParentNode, we cannot yet remove the
DeprecatedString variants of these functions as the Element interface
includes ChildNode and has not yet been ported over from
DeprecatedString.
This allows applying SVG <mask>s to elements. It is only implemented for
the simplest (and default) case:
- mask-type = luminance
- maskContentUnits = maskContentUnits
- maskUnits = objectBoundingBox
- Default masking area
It should be possible to extend to cover more cases. Though the layout
for maskContentUnits = objectBoundingBox will be tricky to figure out.
This allows SVG mask elements to have layout computed, but not connected
to the main paint tree. They should only be reachable if (and painted)
if referenced by the "mask" attribute of another element.
This is controlled by the forms_unconnected_subtree() function on the
paintable, which (if it returns true) prevents the paintable from being
added as a child to what would be its parent.
A Paintable is not created for an SVG <defs> element (nor should it),
but it can contain SVG <mask> elements that need a paintable.
This change forces those paintables to be created (without a parent).
The masks are then only painted by being referenced from another
element.
This change moves steps that can be executed only once and then reused
in subsequent function instantiations from
`function_declaration_instantiation` to the ECMAScriptFunctionObject:
- Determine if there are any parameters with duplicate names.
- Determine if there are any parameters with expressions.
- Determine if an arguments object needs to be created.
- Create a list of distinct function names for which bindings need to
be created.
- Create a list of distinct variable names for which bindings need to
be created.
This change makes React-Redux-TodoMVC test in Speedometer
run 10% faster :)
Unless a new toolchain update has been merged, users should not need to
rebuild their toolchain. Yet, the first thing they see in the build
documentation is to run `Meta/serenity.sh rebuild-toolchain`, which
might incorrectly lead them to use it whenever they encounter an error.
This is a waste of time and causes frustration.
Move any mentions of this option to `Troubleshooting.md` and add a note
to `BuildInstructions.md` about the toolchain build being a one-time
endeavor.
This is in the spirit of commit a4692a6c978a6e66d171e003063449790a6c5879
(and the history behind that commit).
We will need to perform lookups from an integral node ID to the JSON for
that node frequently in the Inspector. We will also need to traverse the
DOM tree from a node, through its ancestors, to the root node. These are
essentially the same maps stored by the Qt Inspector widget.
This commit includes only fetching the DOM tree from the WebContent
process and displaying it in an NSOutlineView. The displayed tree
includes some basic styling (e.g. colors).
When a device is plugged into the machine (and hence, when
`Device::try_create()` is called), then we attempt to load a driver by
calling that driver's probe function.
At any one given time, there can be an abitrary number of USB drivers in
the system. The way driver mapping works (i.e, a device is inserted, and
a potentially matching driver is probed) requires us to have
instantiated driver objects _before_ a device is inserted. This leaves
us with a slight "chicken and egg" problem. We cannot call the probe
function before the driver is initialised, but we need to know _what_
driver to initialise.
This section is designed to store pointers to functions that are called
during the last stage of the early `_init` sequence in the Kernel. The
accompanying macro in `USBDriver` emits a symbol, based on the driver
name, into this table that is then automatically called.
This way, we enforce a "common" driver model; driver developers are not
only required to write their driver and inherit from `USB::Driver`, but
are also required to have a free floating init function that registers
their driver with the USB Core.
We were parsing these all right, but ignoring them in StyleComputer.
No test unfortunately, since we don't currently have a way to delay
the load event until a @font-face has been fully loaded. (Any test
of this right now would be flaky.)
This fixes an issue where the value would be out of sync with reality
in anonymous wrapper block boxes, since we forgot to compute m_visible
after assigning the computed values to them.
Fixes#21106
Support for this element has been removed from all major engines years
ago already, and it's currently the only reason we have a weird
"visible" flag on Layout::Node (which we toggle on a timer here..)
This flag makes the linker bind default-visibility functions locally, so
that calls to them do not have to go through the PLT. This makes it
impossible to override them by preloading a DSO. This was already the
case partially due to `-fno-semantic-interposition`, however that flag
is only able to optimize call sites that are in the same Translation
Unit as the function definitions.
This removes 80% of the PLT relocations in `libjs.so.serenity`.
Obsoletes #20877
This makes CMake pass `-fpie` instead of `-fpic` to the compiler when
building the Kernel and userland *executables*. This allows the compiler
to make certain optimizations based on the fact that the code will be
used in an executable, such as not having to emit `.localalias` symbols.
This leads to a 450 KiB decrease in the size of the Kernel binary.
