The vcpkg install is handled through an action to run vcpkg install with
the private --x-install-root flag that their CMake toolchain file uses
to install dependencies into a build-time directory.
We now use the "report an exception" AO when a script has an execution
error. This has mostly replaced the older "report the exception" AO in
various specifications. Using this newer AO ensures that
`window.onerror` is invoked when a script has an execution error.
Rather than checking the avcodec version in CMake, check it using the
avcodec version macros in the only source file that needs to know about
the AVFrame API/ABI change in version 59.24.100. This is friendlier to
other build systems that would rather avoid configure time checks.
We are currently returning a JSON object of the form:
{
"name": "element-6066-11e4-a52e-4f735466cecf",
"value": "foo"
}
Instead, we are expected to return an object of the form:
{
"element-6066-11e4-a52e-4f735466cecf": "foo"
}
Very similar to commit e5877cda61.
By sending as much data as we can in a single write, we see a massive
performance improvement on WPT tests that hammer WebDriver with errors.
On my Linux machine, this reduces the runtime of:
/webdriver/tests/classic/perform_actions/invalid.py
from 45-60s down to 3-4s.
We must send a Cache-Control header, which then also requires that we
respond with an HTTP/1.1 response (the Pragma cache option is HTTP/1.0).
We should also send the Content-Type header using the same casing as is
written in the WebDriver spec (lowercase).
Both of these are explicitly tested by WPT.
First, this isn't actually helpful, as we no longer store 32-bit values
in JsonValue. They are stored as 64-bit values anyways.
But more imporatantly, there was a bug here when trying to coerce an i64
to an i32. All negative values were cast to an i32, without checking if
the value is below NumericLimits<i32>::min.
Instead of creating a unique new prototype shape every time a function
object is instantiated, we now keep one cached with the intrinsics.
This avoids a whole lot of shape allocations, reducing GC pressure.
Instead of converting images to alpha masks on the CPU, we now delegate
that work to the GPU if possible, by way of SkSL shaders.
This noticeably speeds up https://vercel.com/ which has a ton of SVG
masking going on. The old implementation used 15% of CPU time when
loading the page, this one uses basically none.
I originally believed that this could never receive a null URL and the
spec was inaccurate, but it seems like it can indeed.
I don't have a distilled test, but this makes logging in with GitHub
work on https://v0.dev/
The spec allows us to either treat them as part of the UA origin, or as
its own origin before author styles. This second behaviour turns out to
be what we are currently doing, which is nice!
Funnily enough this was clarified in the spec barely a month after this
original comment was written. :^)
`revert` is supposed to revert to the previous cascade origin, but we
previously had it reverting to the previous layer. To support both,
track them separately during the cascade.
As part of this, we make `set_property_expanding_shorthands()` fall back
to `initial` if it can't find a previous value to revert to. Previously
we would just shrug and do nothing if that happened, which only works
if the value you want to revert to is whatever is currently in `style`.
That's no longer the case, because `revert` should skip over any layer
styles that have been applied since the previous origin.
The build assumed QT or AppKit are the only build UI frameworks. This
extends the default assumption away from that to start experimenting
with building on other platforms.
The `gn` build did not generate the CMake configuration file for the
backtrace module. Update the rules to configure the generated macros
mirroring the CMake build.
It's difficult to know what we need to implement if we silently ignore
these endpoints. Let's log the endpoints and their parameters, and clean
up the wall of FIXME comments to be easier to grok.
The file is not committed to disk until the close which occurs at the
termination of the scope. Extract the `rename` to outside the scope
allowing this to work on Windows. The `download_file` utility downloads
a file in the `gn` build.
WPT uses Python's http.client.HTTPConnection to send/receive WebDriver
messages. For some reason, on Linux, we see an ~0.04s delay between the
WPT server receiving the WebDriver response headers and its body. There
are tests which make north of 1100 of these requests, which adds up to
~44s.
These connections are almost always going to be over localhost and able
the be sent in a single write. So let's send the response all at once.
On my Linux machine, this reduces the runtime of /cookies/name/name.html
from 45-60s down to 3-4s.
If we don't recognize a given transition-property value as a known CSS
property (one that we know about, not necessarily an invalid one),
we should not extrapolate the other transition-foo values for it.
Fixes#1480
https://github.com/whatwg/console/pull/240 is an editorial change to use
the term "implementation-defined" more consistently. This seems to be
the only instance in the spec text which we quote verbatim.
On macOS, it's a bit trickier to not install them, as we're using the
MACOSX_PACKAGE_LOCATION file property to get them into the build
directory and install tree in the same way.
This mainly uses forward declarations as appropriate for input element
related files. This reduces the number of targets being built when we
change HTMLInputElement.h from 430 to 44.
Previously, using `ladybird.sh run` with any target that was part of the
MacOS app bundle would try to run the given executable from the wrong
directory.
This confirmed works on Xcode 16, and Xcode 16.1 Beta 2, with CMake 3.28
or higher.
On linux, the 6.0.0 release from swiftly is still missing my libstdc++
workaround, so it needs a snapshot to work.
When the detected SDK for CMAKE_OSX_SYSROOT and friends has the same
version as your current macOS system version, CMake helpfully doesn't
set CMAKE_OSX_DEPLOYMENT_TARGET. Unfortunately, in this case, swiftc
will default to macOS 10.4, which is absolutely ancient. Grab the target
triple from the -print-target-info JSON when CMAKE_OSX_DEPLOYMENT_TARGET
is not provided at configure time.
Previously, we would crash when attempting to establish a web socket
connection from inside a worker, as we were assuming that the ESO's
global object was a `Window`.
Previously, some otherwise unimplemented WebDriver endpoints were
indicating that they had executed successful, this was causing a large
number of Web Platform Tests to time out when they should have failed.
