Eventually we should not need the layout tree for anything when painting
and this code will only look at the paint tree. For now, this is just
another step in that direction.
I'm about to make StackingContext traverse the paintable tree instead of
actually traversing the layout tree, and it turns out we were not
creating paintables for these SVG elements.
Also switch them to Layout::Box instead of the default InlineNode to
make the trees look a bit less weird. Ultimately, we should do something
specialized for these subtrees, but for now this'll do.
This patch just adds the new root paintable and updates the tests
expectations. The next patch will move painting logic from the layout
viewport to the paint viewport.
Until now, paint trees have been piggybacking on the layout tree for
traversal, and paintables didn't actually have their own parent/child
pointers.
This patch changes that by making Paintable inherit from TreeNode, and
adding a new pass to LayoutState::commit() where we recursively build
the new paint tree.
This makes it possible to specify (instead of is_debug) a more
specialized is_debug_lldb or is_debug_gdb, so that clang outputs the
proper symbols. (For lldb this fixes issues with formatting by
setting -fstandalone-debug)
Instead of assuming that the WebDriver binary is in PATH or the two
most common build directories for our scripts, add a command line
argument to the script to pass a WebDriver binary.
By running ctest -C Integration -R WPT, you can run WPT. Adding just
-C Integration will run all other tests *and* the WPT test.
Also add support for ./Meta/serenity.sh test lagom WPT to serenity.sh
We should be documenting required pacakges elsewhere and installing them
in the setup step of CI.
This also fixes a problem where the run script would fail if you already
had a cloned wpt directory.
Using `Core::Timer` that doesn't implicitly convert callback to
`JS::SafeFunction` fixes the bug when `BrowsingContext` is never
destroyed because of cyclic dependency between callback and
`BrowsingContext`.
Callbacks registered within the SharedImageRequest can be removed after
the request has been completed. This resolves the GC memory leak issue
that occurs due to a cyclic dependency, where the callback captures the
image request while being owned by the image request at the same time.
The proper syntax for defining user-defined literals does not require a
space between the `operator""` token and the operator name:
> error: identifier 'sv' preceded by whitespace in a literal operator
> declaration is deprecated
In FetchAlgorithms, it is common for callbacks to capture realms. This
can indirectly keep objects alive that hold FetchController with these
callbacks. This creates a cyclic dependency. However, when
JS::HeapFunction is used, this is not a problem, as captured by
callbacks values do not create new roots.
This change introduces HeapFunction, which is intended to be used as a
replacement for SafeFunction. The new type behaves like a regular
GC-allocated object, which means it needs to be visited from
visit_edges, and unlike SafeFunction, it does not create new roots for
captured parameters.
