By using separate struct we can avoid updating AST node and
ECMAScriptFunctionObject constructors every time there is a need to
add or remove some additional information colllected during parsing.
The logic in this script was *intended* to use the system's default
compiler if it was sufficiently new, and only start searching for the
latest installed if the default was not suitable.
However, the `cxx` program does not exist on Unixes, so the version
check always failed. We should be using the standard `c++` program name
instead.
After this change, the `CC` and `CXX` environment variables will have to
be used if someone wants to force a newer compiler version.
As it's not uncommon for users to drop the module instance on the floor
after having grabbed the few exports they need to hold on to.
Fixes a few UAFs that show up as "invalid" accesses to
memory/tables/etc.
Allowing an environment variable to enable/disable the build for clangd
and other toolchains will improve the developer-experience than
reconfiguring and building the toolchain manually.
Now you will have to call the command as following
$ CLANG_ENABLE_CLANGD=ON Toolchain/BuildClang.sh
Adds a TextEditor widget to the chess application to display move
history. It is updated whenever Board::apply_move is called to reflect
the current board state.
Now that the lambda capture plugin isn't full of false-positives, we can
make the jump and start halting builds for these errors. It also allows
these plugins to be useful in CI.
Instead of being opt-out with NOESCAPE, it is now opt-in with ESCAPING.
Opt-out is ideal, but unfortunately this was extremely noisy when
compiling the entire codebase. Escaping functions are rarer than non-
escaping ones, so let's just go with that for now.
This also allows us to gradually add heuristics for detecting missing
ESCAPING annotations and emitting them as errors. It also nicely matches
the spelling that Swift uses (@escaping), which is where this idea
originally came from.
We should build file natively as well so it can be used to compile the
target build (for serenity). The Makefile doesn't do this automatically
so to ensure it will not fail due to version mismatch between the host
version and target version, we ensure we always have a native binary at
hand.
I did a mistake and set the kernel_physical_base value to be just on
the actual linked kernel ELF start offset, while this value should
represent together with KERNEL_MAPPING_BASE the actual higher-half load
address.
By changing this value, we resolve a bug in which disabling KASLR
doesn't work and will cause the prekernel to hang on this statement:
```c++
VERIFY(kernel_load_base >= kernel_mapping_base + 0x200000);
```
Allows to skip function environment allocation for non-arrow functions
if the only reason it is needed is to hold `this` binding.
The parser is changed to do following:
- If a function is an arrow function and uses `this` then all functions
in a scope chain are marked to allocate function environment for
`this` binding.
- If a function uses `new.target` then all functions in a scope chain
are marked to allocate function environment.
`ordinary_call_bind_this()` is changed to put `this` value in execution
context when function environment allocation is skipped.

This reverts commit a362c37c8b.
The commit tried to add an unused function that continued our tradition
of not properly waiting for things but instead flooding event loop with
condition checks that delay firing of the event. I think this is a
fundamentally flawed approach. See also checks for
`fire_when_not_visible` in LibCore/EventLoopImplementationUnix.cpp.
This change adds the `width` and `height` properties to
`HTMLVideoElement` and `HTMLSourceElement`. These properties reflect
their respective content attribute values.
With this change, ".*make.*" function family now does error checking
earlier, which improves experience while using clangd. Note that the
change also make them instantiate classes a bit more eagerly, so in
LibVideo/PlaybackManager, we have to first define SeekingStateHandler
and only then make() it.

A connection's socket is allowed to be null if it's being recreated
after a failed connect(), this was handled correctly in
request_did_finish but not in recreate_socket_if_needed; this commit
fixes this oversight.
This allows us to skip allocating a function environment in cases where
it was previously impossible because the arguments object needed a
binding.
This change does not bring visible improvement in Kraken or Octane
benchmarks but seems useful to have anyway.
ReadLoopReadRequest::on_chunk expects an UInt8Array, so make sure we
convert the passed in ByteBuffer to an UInt8Array before passing it to
the AO writable_stream_default_writer_write.

This callback is meant to be triggered by streams, which does not always
provide a WebIDL::DOMException. Pass a plain value instead. Of all the
users of this callback, only one actually uses the value, and already
converts the DOMException to a plain value.
