Instead of wrapping all non-movable members of TransportSocket in OwnPtr
to keep it movable, make TransportSocket itself non-movable and wrap it
in OwnPtr.
This is very clearly a very dangerous API to have, and was causing
a crash on Linux as a result of a stack use-after-free when visiting
https://www.index.hr/.
Fixes#3901
The display list is an immutable data structure, so once it's created,
rasterization can be moved to a separate thread. This allows more room
for performing other tasks between processing HTML rendering tasks.
This change makes PaintingSurface, ImmutableBitmap, and GlyphRun atomic
ref-counted, as they are shared between the main and rendering threads
by being included in the display list.
Exactly one place seems to define these at the moment: service worker
clients. Since we don't have a type for these and just use
EnvironmentSettingsObject, I've put it there.
This allows us to parse the Content-Security-Policy header and
Referrer-Policy header from navigation responses and actually allow
them to start having an effect.
This has been a longstanding ergonomic issue with our IPC compiler. Non-
trivial types were previously passed by const&. So if we wanted to avoid
expensive copies, we would have to const_cast and move the data.
We now pass ownership of all transferred data to the client subclasses.
This allows us to remove const_cast from these methods, and allows us to
avoid some trivial expensive copies that we didn't bother to const_cast.
This is required to store Content Security Policies, as their
Directives are implemented as subclasses with overridden virtual
functions. Thus, they cannot be stored as generic Directive classes, as
it'll lose the ability to call overridden functions when they are
copied.
Explicitly link final targets with OpenSSL to ensure that the vcpkg
version is loaded instead of the system one.
Before this change we would inherit `libcrypto.so` and `libssl.so` from
other dependencies, like Qt, that do not have their RPATH rewritten.
This would cause the loader to prefer the system libraries over the
vcpkg ones causing all sorts of version mismatch issues.
The effectiveness of this change can be verified with
`readelf -d ./bin/Ladybird` showing `libcrypto.so` and `libssl.so` as
direct dependencies, before they would not appear. Additionally, `ldd`
will show `libcrypto.so` and `libssl.so` pointing to the vcpkg builds.
Our existing coalescing mechanism for input events didn't prevent
multiple mousemove/mousewheel events from being processed between paint
cycles. Since handling these events can trigger style & layout updates
solely for hit-testing purposes, we might end up doing work that won't
be observable by a user and could be avoided by shceduling input events
processing to happen right before painting the next frame.
Resulting in a massive rename across almost everywhere! Alongside the
namespace change, we now have the following names:
* JS::NonnullGCPtr -> GC::Ref
* JS::GCPtr -> GC::Ptr
* JS::HeapFunction -> GC::Function
* JS::CellImpl -> GC::Cell
* JS::Handle -> GC::Root
Now that the heap has no knowledge about a JavaScript realm and is
purely for managing the memory of the heap, it does not make sense
to name this function to say that it is a non-realm variant.
The main motivation behind this is to remove JS specifics of the Realm
from the implementation of the Heap.
As a side effect of this change, this is a bit nicer to read than the
previous approach, and in my opinion, also makes it a little more clear
that this method is specific to a JavaScript Realm.
We currently compile the Qt event loop files multiple times, for every
target which wants to use them. This patch moves these to LibWebView as
a central location to avoid this.
