Note that this does not change cycle-detection.
This is also was an unnecessary copy, since there is an easier, less
memory-intense way to do cycle detection than copying the entire
visited_set all the time.
This is technically "undefined behavior" per CSS 2.2, but it seems
sensible to mirror the behavior of max-height in the same situation.
It also appears to match how other engines behave.
Fixes#19242
Specifically, this is to make it easier to save and restore this state
to a config file. I had hoped to use the column names instead of their
IDs, but some columns have an empty string as their name so we wouldn't
be able to distinguish between those.
As it turns out, making everyone piggyback on HTML::ImageRequest had
some major flaws, as HTMLImageElement may decide to abort an ongoing
fetch or wipe out image data, even when someone else is using the same
image request.
To avoid this issue, this patch introduces SharedImageRequest, and then
implements ImageRequest on top of that.
Other clients of the ImageRequest API are moved to SharedImageRequest
as well, and ImageRequest is now only used by HTMLImageElement.
This fixes an issue with image data disappearing and leading to asserts
and/or visually absent images.
The margin from the containing blocks shouldn't be included in the
amount by which we increment x after a float was places. That coordinate
should be relative to the containing block.
Fixes the comments layout on https://lobste.rs.
Methods defined in header files should generally be `inline`,
not `static`.
`static` means that each translation unit will have its own local copy
of the function when the function isn't inlined and it's up to the
linker's identical code folding to hopefully merge the potentially many
copies in the program. `inline` means that the linker can put the
identical copies in a comdat and merge them by name, without having to
compare contents.
No behavior change.
This AO will be used in the Web::FileAPI::Blob::get_stream()
implementation to enqueue all data in the blob to the stream.
There are still plenty of cases to handle, but this appears to be enough
for the basic case of reading all chunks from a readable stream until it
is done.
Both `Database` and `Heap` were allowed to be opened twice. Prevent
this, and change SQLServer to only open databases that are not already
opened.
This fixes a Ladybird crash where opening the application twice would
erroneously duplicate free heap block indices.
The spec says the result of this algorithm is undefined in such cases,
and it appears that other engines yield a zero size.
More importantly, this prevents us from leaking a non-finite value into
the layout tree.
Previously, all StackingContexts which were scaled using CSS transforms
were hard-coded to use BilinearBlend. This fix maps specified
image-rendering properties to reasonable ScalingModes for painting.
