Previously, the check for `.html` meant that `.svg` tests were excluded.
This led to a few `.svg` with missing or bit-rotted expectations, which
have now been added/updated.
Before this change, the rebaseline script would generate reference
based on 'about:blank' (at least running it on my macOS system).
This commit allows 'about:blank' through the assertion and only dumps
the layout tree when theloaded URL matches the one we are interested
in.
The IPC layer between chromes and LibWeb now understands that multiple
top level traversables can live in each WebContent process.
This largely mechanical change adds a billion page_id/page_index
arguments to make sure that pages that end up opening new WebViews
through mechanisms like window.open() still work properly with those
extra windows.
Instead of spawning these processes from the WebContent process, we now
create them in the Browser chrome.
Part 1/N of "all processes are owned by the chrome".
These IPCs are different than other IPCs in that we can't just set up a
callback function to be invoked when WebContent sends us the screenshot
data. There are multiple places that would set that callback, and they
would step on each other's toes.
Instead, the screenshot APIs on ViewImplementation now return a Promise
which callers can interact with to receive the screenshot (or an error).
While it would be more hygienic to get a fresh Navigable each time,
loading `about:blank` still means we discard the current Document.
This does noticeably increase the duration of running the LibWeb test
suite. On my machine, we go from ~5.5 seconds to ~7.7.
Before this change, it was possible for a text test to finish before
on_load_finish() was triggered, resulting in the subsequent test
receiving the load event from the previous test.
This commit un-deprecates DeprecatedString, and repurposes it as a byte
string.
As the null state has already been removed, there are no other
particularly hairy blockers in repurposing this type as a byte string
(what it _really_ is).

It is currently a bit messy to pass these options along from main() to
where WebContent is actually launched. If a new flag were to be added,
there are a couple dozen files that need to be updated to pass that flag
along. With this change, the flag can just be added to the struct, set
in main(), and handled in launch_web_content_process().
We're seeing timeouts for WebWorker based tests in some CI runs. It's
possible that these are legitimate timeouts, so bump the default timeout
to 30sec. When porting the test runner to run on CI, Andreas had to bump
the test timeout from 5 seconds to 10, to 15. It's likely that loading
our ASAN/UBSAN binaries on slow CI machines takes a significant amount
of time. Tests that use the new WebWorker process are spawning yet
another process that needs to load LibWeb and all its dependencies.
When the `--dump-failed-ref-tests` flag is provided, screenshots of the
actual and reference pages will be placed in
`Build/lagom/ladbybird/test-dumps`. This makes it a lot easier to spot
what's wrong with a failing test. :^)
Previously, we used `on_load_finish` to determine when the text test
was completed. This method did not allow testing of async functions
because there was no way to indicate that the runner should wait for
the async call to end.
This change introduces a function in the `internals` object that is
intended to be called when the text test execution is completed. The
text test runner will now ignore `on_load_finish` which means a test
will timeout if this new function is never called.
`test(f)` function in `include.js` has been modified to automatically
terminate a test once `load` event is fired on `window`.
new `asyncTest(f)` function has been introduces. `f` receives function
that will terminate a test as a first argument.
Every test is expected to call either `test()` or `asyncTest()` to
complete. If not, it will remain hanging until a timeout occurs.
Each ref test now links to its reference page with a link tag, in the
same format as WPT:
`<link rel="match" href="reference-page.html" />`
The reference pages have all been moved into a separate `reference/` dir
so that we can just treat every file in `ref/` as a test. There's no
filter to only look at .html files, because we also have a .svg file in
there, and there may be other formats we want to use too. But it's not
too hard to add one if we need it.
We can easily add hooks to notify the browsers of these events if any
implementation-specific handling is needed in the future, but for now,
these only repaint the client, which we can do in ViewImplementation.
Storing the backup bitmap is the same across Browser and Ladybird. Just
peform that work in LibWebView, and handle only the implementation-
specific nuances within the browsers.
This also sets the default callback to do what every non-Serenity
browser is doing, rather than copy-pasting this callback into every
implementation. The callback is still available for any platform which
might want to override the default behavior. For example, OOPWV now
overrides this callback to use FileSystemAccessClient.
The ref tests runner takes screenshots of both the input page and the
expected page, then compares them. Ref testing allows us to catch
painting bugs, which cannot be detected with the layout and text tests
we already have.
With ref tests, we'll likely want to reuse the same expectation page
for multiple inputs. Therefore, there's a `manifest.json` file that
describes the relationship between inputs and expected outputs.
This will help a lot with developing chromes for different UI frameworks
where we can see which helper classes and processes are really using Qt
vs just using it to get at helper data.
As a bonus, remove Qt dependency from WebDriver.
We were super inconsistent about this, with most "new" classes living in
the Ladybird namespace, while "old" ones were in the global namespace,
or even sitting in the Browser namespace.
LibTLS still can't access many parts of the web, so let's hide this
behind a flag (with all the plumbing that entails).
Hopefully this can encourage folks to improve LibTLS's algorithm support
:^).
Re-organize our helper files here a bit, to make a clearer distinction
between Qt-specific helpers and generic non-serenity helpers.
A future commit will move Lagom specific code from LibSQL to ladybird
as well, so that we can see about future generic apis for spawning
helper procesess.
