Copying over every texel (4x`f32x4`) for every texture unit is
relatively expensive. By checking if we even need to remember these
texel values, we reduce the time spent in `rasterize_triangle` by
around 2% as measured in Quake III.
We need a `wxallowed` bind mount for the `ioquake3` binary to be able to
compile and run its executable scripts in memory. Instead of instructing
the user how to do so in `/etc/fstab`, we can now use the fancy
`/etc/fstab.d` facility :^)
Previously, we would precalculate "alpha blend factors" on every
configuration update and then calculate the source and destination
blending factors in one go using all these factors. The idea here was
probably that we would get better performance by avoiding branching.
However, by measuring blending performance in Quake III, it seems that
this simpler version that only calculates the required factors reduces
the CPU time spent in `rasterize_triangle` by 3%.
As a bonus, `GL_SRC_ALPHA_SATURATE` is now also implemented.
When a file cannot be accessed, we currently send errno as the error
code. However, there are system calls which occur (by way of dbgln)
between the failed file access and accessing errno. This prevents the
client-side detection of ENOENT from working.
Instead, send over the error we already have stored in the ErrorOr
object.
This allows the WebDriver to take advantage of the common helper process
spawning code when launching ladybird, and to not assume a particular
directory layout.
Use a list of executables to make sure that we don't miss any of the
applications used by Ladybird and its friends like WebDriver, and make
sure to install include all executables and their runtime dependencies.
Use the new get_paths_for_helper_process method in Ladybird to query
Qt for the runtime path of the current executable as well as the build
directory paths.
Instead of overriding AbstractTableView::row_height() and returning a
hard-coded height for some reason, just remove the override.
This makes tree view row heights honor the current font size.
Previously when there was a very long url that spanned outside of the
address bar, the text shown would be the one starting from the very end
of the url instead of from the beginning, so you would be seeing the
query parameters for example, instead of the domain.
This patch adds a ComboBox to `FilePicker` where the user can select
which file types to show, all files that doesn't have an
extension that's in the selected file type will be hidden.
When creating a FilePicker with `FilePicker::construct` or
`FilePicker::get_open_filepath`, allowed file types can be
specified as the last argument.
If no file types are provided then there will be no visual change in the
GUI.
'All Files' and 'Image Files' have shorthands with
`GUI::FileTypeFilter::all_files()` and
`GUI::FileTypeFilter::image_files()`, respectively.
This allows FileSystemModel to take an optional list of allowed file
extensions which it will use to filter out all files that don't end
with that file extension.
The file extensions are set via `set_allowed_file_extensions` which has
a coresponding `get_allowed_file_extensions`.
Splitting the I2C-related code lets the DisplayConnector code to utilize
I2C operations without caring about the specific details of the hardware
and allow future expansion of the driver to other newer generations
sharing the same GMBus code.
We should require a timeout for GMBus operations always, because faulty
hardware could let us just spin forever. Also, if nothing is listening
to the bus (which should result in a NAK), we could also spin forever.
Thanks to Andrew Kaster, which gave a review back in October, about a
big PR I opened (#15502), I managed to figure out why we always had a
problem with the first byte being read into the EDID buffer with the
GMBus code. It turns out that this simple invalid cast was making the
entire problem and using the correct AK::Array::data() method fixed this
notorious long standing problem for good.
This patch removes the x86 mechanism for calling syscalls, favoring
the more modern syscall instruction. It also moves architecture
dependent code from functions that are meant to be architecture
agnostic therefore paving the way for adding more architectures.
The function signal_trampoline_dummy was using int 0x82 to call
SC_sigreturn. Since x86 is no longer supported, the correct way
to call a syscall is using the syscall instruction.
This paves the way to remove the syscall trap handling mechanism.
These changes will prevent duplication of code later when there will
also be the possibility to navigate to the homepage url as defined in
the settings on startup.
This patch also includes some changes in the way that the environment
and arguments are passed to `exec`. It was needed to fit the signature
of `Core::System::exec`. That's beneficial though, as we are now doing
`String` manipulation in a fallible environment, so we can propagate
more errors.
icc-v4.jpg is Meta/Websites/serenityos.org/happy/3rd/bgianf.jpg.
There are a whole bunch of jpgs with v4 color profiles and I just picked
one fairly arbitrarily. It looks like a fairly standard v4 matrix
profile that in this form is also present in many jpgs taken by mobile
phone cameras. It uses parametric curves.
icc-v2.png is based on ./Documentation/WebServer_localhost.jpg since
that is the only image in the repo with a v2 color profile. It also has
all kinds of interesting and somewhat exotic tags, such as an 'dscm' (an
Apple extension to have a description of type 'mluc', since normal
'desc' is required ot have type 'desc' in v2 files -- in v4, 'desc' has
type 'mluc') tag of type 'mluc' that actually contains data in several
languages and that exercises the non-BMP UTF-16BE decoder. It's however
still also a fairly standard v2 matrix profile, which uses 'curv'
instead of 'para' for its curves ('para' is v4-only).
I converted that jpeg file to png, and cropped most of the image
data to save on file size by running:
sips -s format png --cropToHeightWidth 21 42 in.jpg --out out.png
ICC::Profile deletes these objects via base class pointers, so this
is needed that destructors in the subclasses get called.
(Found by asan on CI when adding test coverage.)
Some tests, such as those under LibGL, try to load shared libraries at
runtime which are stored in Build/lagom. Because all tests' working
directory is that of their CMakeLists.txt file, they fail to find those
shared libraries at runtime.
Set LD_LIBRARY_PATH to Build/lagom so the tests may find the shared
libraries. This fixes, for example, both of these commands:
./Meta/serenity.sh test lagom TestAPI
./Meta/serenity.sh run lagom TestAPI
When we call add_test() from each test's CMakeLists.txt, we specify the
working directory to be that of the CMakeList.txt file itself. Create a
property to store that directory and reference it when run-lagom-target
is invoked by serenity.sh.
Note that for non-test Lagom targets which do not set this property, the
working directory will be Build/lagom (because the property will be the
empty string, which CMake resolves relative to the current build path).
