Increase the step timeouts on Linux from 50 to 75 milliseconds, since
we're seeing the occasional timeout on CI. For macOS, we should probably
be able to execute the tests a bit quicker than 500ms per step.
This reverts commit a73cd88f0c.
Emitting SaveLayer for each paintable made rasterization a lot slower
on every website because now Skia has to allocate enormous amounts of
temporary surfaces. Let's revert it for now and figure how to implement
it with less aggressive SaveLayer usage.
PrimitiveString is now internally either UTF-8, UTF-16, or both.
We no longer convert them to/from ByteString anywhere, nor does VM have
a ByteString cache.
When we build internal pages (e.g. about:settings), there is currently
quite a lot of boilerplate needed to communicate between the browser and
the page. This includes creating IDL for the page and the IPC for every
message sent between the processes.
These internal pages are also special in that they have privileged
access to and control over the browser process.
The framework introduced here serves to ease the setup of new internal
pages and to reduce the access that WebContent processes have to the
browser process. WebUI pages can send requests to the browser process
via a `ladybird.sendMessage` API. Responses from the browser are passed
through a WebUIMessage event. So, for example, an internal page may:
ladybird.sendMessage("getDataFor", { id: 123 });
document.addEventListener("WebUIMessage", event => {
if (event.name === "gotData") {
console.assert(event.data.id === 123);
}
});
To handle these messages, we set up a new IPC connection between the
browser and WebContent processes. This connection is torn down when
the user navigates away from the internal page.
This adds a command for saving the current layer of the canvas.
This is useful for painting content onto a blank background in
isolation and later compositing it onto the canvas.
This makes them accessible outside of PropertyParsing.cpp (which will be
useful if/when descriptors can include them). I've also renamed them to
use the correct term: "arbitrary substitution function".
It might be useful to have these artifacts, even for older commits. As
an added bonus, this causes the JS benchmarks to run as well giving us
more datapoints.
This fixes the frame-ancestors WPT tests from crashing when an iframe
is blocked from loading. This is because it would get an undefined
location.href from the cross-origin iframe, which causes a crash as it
expects it to be there.
If we don't have parameter expressions, we don't need to collect
metadata about whether instantiated var names collide with parameter
names or function names, as these flags are only used in the parameter
code path.
This avoids going through all the shape transitions when setting up the
most common form of ESFO.
This is extremely hot on Uber Eats, and this provides some relief.
With search enabled:
- For a single word that does not look like a url: search (a
reported bug).
- If no suffix or a suffix that is not recognized: search.
In general:
- Respect the user's choice if they specified a scheme.
- Respect localhost and registered TLDs.
- As before, add file:// to filesystem files that exist.
We can use the index's invalid state to signal an empty optional.
This makes Optional<IdentifierTableIndex> 4 bytes instead of 8,
shrinking every bytecode instruction that uses these.
Whenever we generate line boxes, we might end up with a residual
vertical float clearance by way of having a `<br>` with `clear: ..` set.
Set the Y offset of the next block level box to place by this vertical
clearance.
Relates to #4058.
This involves yeeting the 'invalid' union member as it was not really
checked against properly anyway; now the 'invalid' state is simply
StringData*{nullptr}, which was assumed to not exist previously.
Note that this is still accessing inactive union members, but is
promising to the compiler that they're fine where they are (the provided
debug macro AK_STRINGBASE_VERIFY_LAUNDER_DEBUG makes the
would-be-UB-if-not-for-launder ops verify that the operation is correct)
Should fix the GCC build.
