Just have all the timing functions return 0 for now.
We can now run the Shynet JS on https://linus.dev/ although the XHR
is rejected by our same-origin policy.
Since Web::Bindings::WindowObject inherits from JS::GlobalObject, it
cannot also inherit from Web::Bindings::EventTargetWrapper.
However, that's not actually necessary. Instead, we simply set the
Window object's prototype to the EventTargetPrototype, and add a little
extra branch in the impl_from() function that turns the JS "this" value
into a DOM::EventTarget*.
With this, you can now call window.addEventListener()! Very cool :^)
Fixes#4758.
Instead of each IDL interface wrapper having its own set of all the
attributes and functions, they are moved to the prototype. This matches
what we already do in LibJS.
Also, this should be spec compliant with the web as well, though there
may be *some* content out there that expects some things to be directly
on the wrapper since that's how things used to work in major browsers
a long time ago. But let's just not worry about that for now.
More work towards #4789
We now instantiate all the generated web API constructors and expose
them on the window object. We also set the generated prototypes on
instantiated wrappers.
Also, we should obviously find a way to generate this code. :^)
This patch adds a FooPrototype and FooConstructor class for each IDL
interface we generate JS bindings for.
These classes are very primitive and don't do everything they should
yet, but we have to start somewhere. :^)
Work towards #4789
This file was useful for debugging a long time ago, but has bitrotted
at this point. Instead of updating it, let's just remove it since
nothing is using it.
This adds support for FUTEX_WAKE_OP, FUTEX_WAIT_BITSET, FUTEX_WAKE_BITSET,
FUTEX_REQUEUE, and FUTEX_CMP_REQUEUE, as well well as global and private
futex and absolute/relative timeouts against the appropriate clock. This
also changes the implementation so that kernel resources are only used when
a thread is blocked on a futex.
Global futexes are implemented as offsets in VMObjects, so that different
processes can share a futex against the same VMObject despite potentially
being mapped at different virtual addresses.
This sort-of matches what some other systems do and seems like a
generally sane thing to do instead of allowing programs to spawn a
child with a nearly full stack.
When freeing an inode, we were checking if it's a directory *after*
wiping the inode metadata. This caused us to forget updating the block
group descriptor with the new directory count.
We forgot to remove the automatic SMAP disablers after fixing up all
this code to not access userspace memory directly. Let's lock things
down at last. :^)
The generic is<T>() uses dynamic_cast which is fine in the majority
of cases, but when one of them shows up in profiles, we can make it
faster by answering the is-a question manually.
All users of this mechanism have been switched to anonymous files and
passing file descriptors with sendfd()/recvfd().
Shbufs got us where we are today, but it's time we say good-bye to them
and welcome a much more idiomatic replacement. :^)
Let's keep things consistent, .diff is the name we use pretty much
everywhere. Also tweak the glob in .port_includes.sh to be
'patches/*.patch' rather than just 'patches/*'.
decode_png_chunks() is not handling "critical" chunks, unlike
decode_png_size() for example. When we encounter a chunk decoding
failure, e.g. because not enough bytes were left to read, just continue
with decoding the bitmap - which will fail on its own, if we're missing
some required chunk(s).
Fixes#4984.
These are 2x the smallest 4 resolutions. When picking one of these
in 1x and then half the size in 2x, the window server adjust the
ui scale factor, but the actual framebuffer size doesn't change.
2560x1440 also happens to be 5k resolution and monitors with that
resolution do exist -- so that seems like a good upper limit :)
For now, only support 1x and 2x scale.
I tried doing something "smarter" first where the UI would try
to keep the physical resolution constant when toggling between
1x and 2x, but many of the smaller 1x resolutions map to 2x
logical resolutions that Compositor rejects (e.g. 1024x768 becomes
512x384, which is less than the minimum 640x480 that Compositor
wants) and it felt complicated and overly magical.
So this instead just gives you a 1x/2x toggle and a dropdown
with logical (!) resolutions. That is, 800x600 @ 2x gives you
a physical resolution of 1600x1200.
If we don't like this after trying it for a while, we can change
the UI then.
To support this, the GUI process and the WebContent service will now
coordinate their backing store bitmaps. Each backing store can be
referred to by a serial ID, and we don't need to keep resending it
as a file descriptor.
We should probably do something similar in WindowServer. :^)
