This brings the SVG API closer to the rest of LibWeb
|
|
This will be used to transmit any svg-relevant data between svg nodes.
This is prep for moving a lot of the SVG logic into Layout nodes.
|
|
This allows layout nodes to do some setup before their children paint,
and cleanup after their children paint. This will be used for SVG
components, where their attributes (like stroke width, fill color, etc)
need to be correctly propogated to layout nodes down the line.

This is a hack to stop chewing CPU on sites that use a font we don't
have and have a lot of text or changes text often.
Examples are the Serenity 2nd birthday page and the JS specification.
|
|
When changing the attributes of an existing property of an object with
unique shape we must not change the PropertyMetadata offset.
Doing so without resizing the underlying storage vector caused an OOB
write crash.
Fixes #3735.

We were forgetting to account for the padding-bottom of the previous
relevant sibling when placing blocks vertically.

We are adding the process name as prefix and a newline as suffix to any
message written to debug. Thus, the following doesn't make any sense:
for (u8 byte : bytes)
dbg("{:02x} ", byte);
dbgln();
Which function call would put the prefix? This doesn't make any sense,
thus these functions must go.
The example above could be converted to:
StringBuilder builder;
for (u8 byte : bytes)
builder.appendff("{:02x} ", byte);
dbgln("{}", builder.build());

No behavior change.

Problem:
- Constructors and conversion operators are not `constexpr`,
but they can be.
- `constexpr` is needed here so that other classes can add `constexpr`
evaluation.
Solution:
- Add the `constexpr` keyword to the constructors and
conversion operators.
- Add `static_assert` tests which ensure the capability works.

Previously, when a loop detected an unwind of type ScopeType::Function
(which means a return statement was executed inside of the loop), it
would just return undefined. This set the VM's last_value to undefined,
when it should have been the returned value. This patch makes all loop
statements return the appropriate value in the above case.
|
|
For some reason, this was never added. So something like "while (true)
{ return }" would loop infinitely.
|
|
This matches behavior on Linux, macOS, Windows, and it makes it possible
to hit ctrl-L arrow-right ctrl-backspace to edit the last component of
an URL in browser, or of the current path in File Manager.
Also make it so that ctrl-left/right does a word movement that starts
at the edge of the selection. This matches Linux and macOS, but not
Windows (which instead does a word movement relative to the cursor,
not the selection edge).

Previously we'd only pick up background-image when it was part of the
background shorthand.
CSS property application remains hackish, lots of room for improvement
in this area. :^)
|
|
Widgets should respect the background/foreground roles in a way that
makes sense for the widget.

This is cheating a little bit as we don't set the document to a nullptr
as in InProcessWebView, but the observable outcome is the same. :^)
|
|
|
|
|
|
This makes it possible for the WebView to resolve relative paths in
documents loaded from a file.
|
|
|
|
|
|
|
|
|
|
This moves responsibility for parsing and loading the document
from InProcessWebView to FrameLoader, so can be re-used easily.
|
|
'continue' is no longer allowed outside of a loop, and an unlabeled
'break' is not longer allowed outside of a loop or switch statement.
Labeled 'break' statements are still allowed everywhere, even if the
label does not exist.
|
|
To avoid including paths from the build environment in the binaries.
A step towards having reproducible builds.

MemberExpression::computed_property_name()
No need for duplicating this logic.
|
|
It was converting *any* number to an i32 index, which obviously is not
correct for negative ints, doubles, infinity and nan.
Fixes #3712.

Problem: Defining the destructor violates the "rule of 0" and prevents
the copy/move constructor/assignment operators from being provided by
the compiler.
Solution: Change the constructor and destructor to be the default
compiler-provided definition.

In case we want to rely more on TSC in time keeping in the future, idk
This adds:
- RDTSCP, for when the RDTSCP instruction is available
- CONSTANT_TSC, for when the TSC has a constant frequency, invariant
under things like the CPU boosting its frequency.
- NONSTOP_TSC, for when the TSC doesn't pause when the CPU enters
sleep states.
AMD cpus and newer intel cpus set the INVSTC bit (bit 8 in edx of
extended cpuid 0x8000000008), which implies both CONSTANT_TSC and
NONSTOP_TSC. Some older intel processors have CONSTANT_TSC but not
NONSTOP_TSC; this is set based on cpu model checks.
There isn't a ton of documentation on this, so this follows Linux
terminology and http://blog.tinola.com/?e=54
CONSTANT_TSC:
https://github.com/torvalds/linux/commit/39b3a7910556005a7a0d042ecb7ff98bfa84ea57
NONSTOP_TSC:
https://github.com/torvalds/linux/commit/40fb17152c50a69dc304dd632131c2f41281ce44
qemu disables invtsc (bit 8 in edx of extended cpuid 0x8000000008)
by default even if the host cpu supports it. It can be enabled by
running with `SERENITY_QEMU_CPU=host,migratable=off` set.

Why does this class exist anyways? What is wrong with using
StringBuilder?
