Object.defineProperty() can now change the attributes of a property
already on the object. Internally this becomes a shape transition with
the TransitionType::Configure. Such transitions don't expand the
property storage capacity, but rather simply keep attributes up to date
when generating a property table.
We now care (a little bit) about the "configurable" and "writable"
property attributes.
Property attributes are stored together with the property name in
the Shape object. Forward transitions are not attribute-savvy and will
cause poor Shape reuse in the case of multiple same-name properties
with different attributes.
Oh, and this patch also adds Object.getOwnPropertyDescriptor() :^)
There was a frequently occurring pattern of "map this physical address
into kernel VM, then read from it, then unmap it again".
This new typed_map() encapsulates that logic by giving you back a
typed pointer to the kind of structure you're interested in accessing.
It returns a TypedMapping<T> that can be used mostly like a pointer.
When destroyed, the TypedMapping object will unmap the memory. :^)
If we don't support ACPI, just don't instantiate an ACPI parser.
This is way less confusing than having a special parser class whose
only purpose is to do nothing.
We now search for the RSDP in ACPI::initialize() instead of letting
the parser constructor do it. This allows us to defer the decision
to create a parser until we're sure we can make a useful one.
We already have "global" as a way to access the global object in js(1)
(both REPL and script mode). This replaces it with "globalThis", which
is available in all environments, not just js.
This is a stop-gap patch solution for the annoying problem of models
being bad at updating. At least the process table will retain your
selection in SystemMonitor now.
In order to complete a relative URL, we need a Document. Fix this by
giving XMLHttpRequest a pointer to its window object. Then we can go
from the window to the document, and then we're home free. :^)
This patch adds very basic XMLHttpRequest support to LibWeb. Here's an
example that currently works:
var callback = function() { alert(this.responseText); }
var xhr = new XMLHttpRequest();
xhr.addEventListener("load", callback);
xhr.open("GET", "http://serenityos.org/~kling/test/example.txt");
xhr.send();
There are many limitations and bugs, but it's pretty dang awesome that
we have XHR. :^)
`IRCChannelMemberListModel->nick_at` returns the nick name of a channel
member at the specified index.
`IRCClient->nick_without_prefix` returns a formatted nick name without
privilege prefix.
- Get rid of the PCI::Initializer object which was not serving any real
purpose or holding any data members.
- Move command line parsing from init to PCI::initialize().
Instead of nesting a bunch of heap allocations, just store them in
a simple HashMap<u16, MMIOSegment>.
Also fix a bunch of double hash lookups like this:
ASSERT(map.contains(key));
auto thing = map.get(key).value();
They now look like this instead:
auto thing = map.get(key);
ASSERT(thing.has_value());
- Make things const when they don't need to be non-const.
- Don't return AK::String when it's always a string literal anyway.
- Remove excessive get_ prefixes per coding style.
