When a mallocation is shrunk/grown without moving, UE needs to update
its precise metadata about the mallocation, since it tracks *exactly*
how many bytes were allocated, not just the malloc chunk size.
This is necessary because cache reusability will be determined by Github Actions.
Note that we only cache if explicitly asked to do so,
which only happens on Github Actions.
Form submissions to file:// URLs are now permitted only if the
submitting document is also a file:// URL and the form method is "get".
Form submissions to URLs with a http(s):// URL protocol are permitted.
Form submissions for all other URL protocols are rejected.
When computing the list of blocks to deallocate when freeing an inode,
we would stop collecting blocks after reaching the inode's block count.
Since we're getting rid of the inode, we need to also include the meta
blocks used by the on-disk block list itself.
Keeping the VM call frames in a Vector could cause them to move around
underneath us due to Vector resizing. Avoid this issue by allocating
CallFrame objects on the stack and having the VM simply keep a list
of pointers to each CallFrame, instead of the CallFrames themselves.

As the global object is constructed and initialized in a different way
than most other objects we were not setting its prototype! This made
things like "globalThis.toString()" fail unexpectedly.
If value.to_string() throws an exception and returns a null string we
must create an invalid StringOrSymbol, not one from the null string
(which ASSERT()s).
* Change the register structures to use the volatile keyword explicitly
on the register values. This avoids accidentally omitting it as any
access will be guaranteed volatile.
* Don't assume we can read/write 64 bit value to the main counter and
the comparator. Not all HPET implementations may support this. So,
just use 32 bit words to access the registers. This ultimately works
around a bug in Bochs 2.6.11 that loses 32 bits of a 64 bit write to
a timer's comparator register (it internally writes one half and
clears the Tn_VAL_SET_CNF bit, and then because it's cleared it
fails to write the second half).
* Properly calculate the tick duration in calculate_ticks_in_nanoseconds
* As per specification, changing the frequency of one periodic timer
requires a restart of all periodic timers as it requires the main
counter to be reset.
Some things, like (the non-generic version of) Array.prototype.pop(),
check is_empty() to determine whether an action, like removing elements,
can be performed. We need to know the array-like size for that, not the
size of the underlying storage, which can be different - and is not
something IndexedProperties should expose so I removed its size().
Fixes#3948.
- We have to check if the property name is a string before calling
as_string() on it
- We can't as_number() the same property name but have to use the parsed
index number
Fixes#3950.
We had competing inline definitions of the placement operators new.
Avoid this by having <AK/kmalloc.h> pull in <new> from the compiler
and always using their definitions instead.
I feel like there must be an elegant solution to this whole situation
with the operators, but I'm not sure what it is.
We can't assume that property names can be converted to strings anymore,
as we have symbols. Use name.to_value() instead.
This makes something like this possible:
new Proxy(Object, { get(t, p) { return t[p] } })[Symbol.hasInstance]
This was probably a result of search & replace, it's quite ridiculous in
some places. Let use the existing pattern of getting a reference to the
VM once at each function start consistently.
This allows issuing asynchronous requests for devices and waiting
on the completion of the request. The requests can cascade into
multiple sub-requests.
Since IRQs may complete at any time, if the current process is no
longer the same that started the process, we need to swich the
paging context before accessing user buffers.
Change the PATA driver to use this model.
