Many other parsers call it with this name.
Also Type can be confusing in this context since the DeclarationType is
not the type (number, string, etc.) of the variables that are being
declared by the VariableDeclaration.
Some IRC clients use /hop to part and re-join a channel; however this
can be confused with granting half-op (+h) channel privileges to a user.
The general convention used by other IRC clients is /cycle.
Add an implementation of CanvasRenderingContext2DWrapper.strokeRect().
While implementing this I fixed fillRect() and the new strokeRect() to
honor the .scale() and .translate() values that had previously been plumbed.
Also enhance the canvas.html demo to utilize strokeRect(), scale(), and translate().
Note: clang only (see https://llvm.org/docs/LibFuzzer.html)
- add FuzzJs which will run the LibJS parser on random javascript inputs
- added a basic dictionary of javascript tokens
To use fuzzer:
CC=/usr/bin/clang CXX=/usr/bin/clang++ cmake -DENABLE_FUZZER_SANITIZER=1 ..
Fuzzers/FuzzJs -dict=../Fuzzers/FuzzJs.dict
Every Document now has an Origin, found via Document::origin().
It's based on the URL of the document.
This will be used to implement things like the same-origin policy.
Clang keeps whining that NonnullFooPtrs are in "unknown" state and I'm
not sure how to resolve that right now. Disable the checking until we
can figure it out.
To make repeated symbolication requests faster, we now cache the symbol
count on ELFLoader instead of looking it up in the image each time.
We also cache the demangled versions of names after looking them up the
first time. This is a huge speedup for ProfileViewer. :^)
Running event handlers in response to a mouse event may cause full
layout invalidation, so we can't expect the layout root to be present
right after returning from JS.
Fixes#1629.
The PropertyName class able to match a number or an array can only
accept positive numerical values. However, the computed_property_name
method sometimes returned negative values.
This commit also adds a basic object access test case.
This patch adds a new kind of JS::Value, the empty value.
It's what you get when you do JSValue() (or most commonly, {} in C++.)
An empty Value signifies the absence of a value, and should never be
visible to JavaScript itself. As of right now, it's used for array
holes and as a return value when an exception has been thrown and we
just want to unwind.
This patch is a bit of a mess as I had to fix a whole bunch of code
that was relying on JSValue() being undefined, etc.
Now that we have two separate storages for Object properties depending
on what kind of index they have, it's nice to have an abstraction that
still allows us to say "here's a property name".
We use PropertyName to always choose the optimal storage path directly
while interpreting the AST. :^)
Objects can have both named and indexed properties. Previously we kept
all property names as strings. This patch separates named and indexed
properties and splits them between Object::m_storage and m_elements.
This allows us to do much faster array-style access using numeric
indices. It also makes the Array class much less special, since all
Objects now have number-indexed storage. :^)
These functions are using a naive approach: casting double/float to int
and returning the result + 1. That increment by one must only happen for
positive input values though.
In contrast to the previous patchset that was reverted, this time we use
a "special" method to access a file with block size of 512 bytes (like
a harddrive essentially).
