These classes only needed Window to get at its realm. Pass a realm
directly to construct DOM and WebIDL classes.
This change importantly removes the guarantee that a Document will
always have a non-null Window object. Only Documents created by a
BrowsingContext will have a non-null Window object. Documents created by
for example, DocumentFragment, will not have a Window (soon).
This incremental commit leaves some workarounds in place to keep other
parts of the code building.
In this generator change, we introduce a new factory method for bound
LibWeb objects that takes a JS::Realm instead of Web::HTML::Window.
The two methods are allowed to co-exist at this point, but the option to
take an HTML::Window will be removed once all clases are converted to
the new API.
We also start using the new Bindings::ensure_web_[prototype/constructor]
helpers from the Bindings/Intrinsics class so that we can eventually
remove the helpers from Window.h for the same.
This Intrinsics object hangs off of a new HostDefined struct that takes
the place of EnvironmentSettingsObject as the true [[HostDefined]] slot
on JS::Realm objects created by LibWeb.
This gets the intrinsics off of the GlobalObject, Window, similar to the
previous refactor of LibJS to move the intrinsics into the Realm's
[[Intrinics]] internal slot.
A side effect of this change is that we cannot fully initialize a Window
object until the [[HostDefined]] slot has been installed into the realm,
which happens with the creation of the WindowEnvironmentSettingsObject.
As such, any Window usage that has not been funned through a WindowESO
will not have any cached Web prototyped or constructors, and will not
have Window APIs available to javascript code. Currently this seems
limited to usage of Window in the CSS parser, but a subsequent commit
will clean those up to take Realm as well. However, this commit compiles
so let's cut it off here :^).
Clang patch D116203 added various builtin functions for type traits,
`__decay` being one of them. This name conflicts with our
`AK::Detail::__decay`, leading to compiler warnings with Clang 16.
This matches how LibMain is used within Serenity. This commit makes it
possible to build Lagom with LTO. Previously, `serenity_main` functions
would be dead-stripped away, as the linker could prove that nothing from
the executable ever called them.
This keeps us from accidentally building toolchains that don't make it
through a clean build if we build them using a populated sysroot, as it
would otherwise detect libpthread and friends and try to pull them in
while LibC is not yet built.
If the stored symbol is custom (non-global), it is allocated on the
heap, and may not be visited by anyone else, so we must register it in
order to keep it alive.
This was previously indirectly forcing Heap/Handle.h to include it
instead. This will let us include Handle.h from PropertyKey, which will
allow us to solve a different issue.
The BootFramebufferConsole class maps the framebuffer using the
MemoryManager, so to be able to draw the logo, we need to get this
mapped framebuffer. This commit adds a unsafe API for that.
The MemoryManager now works, so we can use the same code as on x86 to
map the framebuffer. Since it uses the MemoryManager, the initialization
of the BootFramebufferConsole has to happen after the MemoryManager is
working.
For the initial page tables we only need to identity map the kernel
image, the rest of the memory will be managed by the MemoryManager. The
linker script is updated to get the kernel image start and end
addresses.
The page table and page directory formats are architecture specific, so
move the headers into the Arch directory. Also move the aarch64 page
table constants from aarch64/MMU.cpp to aarch64/PageDirectory.h.
When an exception happens it is sometimes hard to figure out where
exactly the exception happened, so use the frame pointer of the trap
frame to print a backtrace.
Previously Welcome relied on a bogus executable key value to disable
startup. This always printed an error on login and littered the config
file with a useless entry. Adding/removing the group as needed seems
a bit nicer.
