`WebIDL::invoke_callback()` now takes an `exception_behavior`
parameter, which can be set to `report` to report an exception before
returning. Setting `exception_behavior` to `rethrow` retains the
previous behavior.
This way we could be sure that context object won't be deallocated
before any of the objects that belong to it.
Having a context pointer is also going to be used in upcoming changes
to generate an INVALID_OPERATION error if an object does not belong to
the context it's being used in.
Make sure that `HashAlgorithmIdentifier` is passed through
`normalize_an_algorithm` to verify that the hash is valid and supported.
This is required by the spec, but we are not following it very strictly
in `normalize_an_algorithm` because it is pretty convoluted.
Fixes ~60 tests.
CSS filters work similarly to canvas filters, so it makes sense to have
Gfx::Filter that can be used by both libraries in an analogous way
as Gfx::Color.
Without this, a crashing ref test is able to take down the entire
process because of the `VERIFY(!m_pending_screenshot);` in
`take_screenshot()`. The dialog/prompt fields were not causing crashes
but clearing them feels more hygienic.
Add a formatter output to the flake (`nix fmt`), along with moving +
renaming the devshell so it will work by running `nix-shell` in the root
of the project.
Previously we created a tree of CalculationNodes with dummy
UnparsedCalculationNode children, and then swapped those with the real
children. This matched the spec closely but had the unfortunate
downside that CalculationNodes couldn't be immutable, and couldn't know
their properties at construct-time. UnparsedCalculationNode is also a
footgun, as if it gets left in the tree accidentally we would VERIFY().
So instead, let's parse the calc() tree into an intermediate format, and
then convert each node in that tree, depth-first, into its
corresponding CalculationNode. This means each CalculationNode knows
what its children are when it is constructed, and they never change.
Apart from deleting UnparsedCalculationNode, we can also get rid of the
for_each_child_node() method that was only used by this "replace the
children" code.
Fixes multiple slightly wrong behaviours of the `deriveBits` method
across various algorithms. Some of them might be due to a spec update.
Add tests related to fixes.
Apart from the fact that this workflow is failing every time, we don't
need to check the branch we're on since it's only invoked for the
default branch of the repository. We can also remove the `always()`
since there are no job dependencies nor do we want this to be
uncancelable.
