If QEMU has the qemu_vdagent chardev (should be present in QEMU 6.1)
then we use that as the SPICE client.
If qemu_vdagent is not present, no SPICE client will be launched by
default because it makes the display a bit choppy.
Set SERENITY_SPICE to override the default behavior and use your default
SPICE client.
Let's remove the qcmd and q35_cmd options and instead have a simple
"q35" run option. Specifiying the kernel command line was a neat trick
I personally used for many debug sessions, but it seems better to stick
to setting it internally in the kernel or modifying the shell
SERENITY_KERNEL_CMDLINE environment variable to do this.
With this change, we use 6 PCIe root ports in the Q35 machine, and plug
the bochs-display device into one of those PCIe ports.
We plug the bochs-display as function 0 of that device, because
otherwise SeaBIOS and also the kernel will not detect its presence.
Unfortunately we can't just use --chown everywhere because only rsync
version 3.1 and newer support it and the default rsync on macOS is
2.6.9.
Fixes#8711.
SDL brings with it an annoying issue whereby trying to resize the window
before Serenity starts up prevents it from automatically resizing to fit
the screen.
This patch makes the previous behavior (i.e using the GTK backend) the
default unless SERENITY_SCREENS is greater than 1.
This patch introduces the SQLServer system server. This service is
supposed to be the only process/application talking to database storage.
This makes things like locking and caching more reliable, easier to
implement, and more efficient.
In LibSQL we added a client component that does the ugly IPC nitty-
gritty for you. All that's needed is setting a number of event handler
lambdas and you can connect to databases and execute statements on them.
Applications that wish to use this SQLClient class obviously need to
link LibSQL and LibIPC.
This adds a utility program which is essentially a command generator for
CMake. It reads the 'components.ini' file generated by CMake in the
build directory, prompts the user to select a build type and optionally
customize it, generates and runs a CMake command as well as 'ninja
clean' and 'rm -rf Root', which are needed to properly remove system
components.
The program uses whiptail(1) for user interaction.
These are usually incorrect, and people sometimes forget to add the
correct values as a result of them being optional, so they should just
be specified explicitly.
This removes all usages of the non-standard define_property helper
method and replaces all it's usages with the specification required
alternative or with define_direct_property where appropriate.
I didn't add any debug logging to the object rewrite, so this is now
unused. It's much more correct though, so we can get away with adding
ad-hoc logging, should that ever be necessary :^)
Side note: this should have a prefix, i.e. JS_OBJECT_DEBUG. The previous
name is too generic.
All GUI applications currently load all TTF fonts on startup
(to populate the Gfx::FontDatabase. This could probably be smarter.)
Before this patch, everyone would open the files and read them into
heap-allocated storage. Now we simply mmap() them instead. :^)
This reverts commit a808fff2ec.
I highly suspect the reason it was not working before was fixed in
017c5fc7d9, so the SB16 DMA can work even
if we initialize another E1000 network adapter.
QEMU appears to always relay absolute mouse coordinates relative to the
screen that the mouse is pointed to, without any way for us to know
what screen it was. So, when dealing with multiple displays force using
relative coordinates only.
This allows specifying how many screens we should use. This also then
only enables virtio-gpu if more than one display is requested.
This also adds an environment variable SERENITY_QEMU_DISPLAY_BACKEND
which allows overriding the default qemu display backend, as it may
not be available.
Multiboot only supports ELF32 executables. This changes the build
process to build an ELF32 executable which has a 32-bit entry point,
but consists of mostly 64-bit code.
`wasm-as` will do some semantic analysis on the modules, which is not
something we're looking for here.
Instead, use `wat2wasm` to generate the exact module.
Components are a group of build targets that can be built and installed
separately. Whether a component should be built can be configured with
CMake arguments: -DBUILD_<NAME>=ON|OFF, where <NAME> is the name of the
component (in all caps).
Components can be marked as REQUIRED if they're necessary for a
minimally functional base system or they can be marked as RECOMMENDED
if they're not strictly necessary but are useful for most users.
A component can have an optional description which isn't used by the
build system but may be useful for a configuration UI.
Components specify the TARGETS which should be built when the component
is enabled. They can also specify other components which they depend on
(with DEPENDS).
This also adds the BUILD_EVERYTHING CMake variable which lets the user
build all optional components. For now this defaults to ON to make the
transition to the components-based build system easier.
The list of components is exported as an INI file in the build directory
(e.g. Build/i686/components.ini).
Fixes#8048.
This commit adds a bunch of passes, the most interesting of which is a
pass that merges blocks together, and a pass that places blocks that
flow into each other next to each other, and a very simply pass that
removes duplicate basic blocks.
Note that this does not remove the jump at the end of each block in that
pass to avoid scope creep in the passes.
These are the actual structures that allow USB to work (i.e the ones
actually defined in the specification). This should provide us enough
of a baseline implementation that we can build on to support
different types of USB device.
These are pretty common on older LGA1366 & LGA1150 motherboards.
NOTE: Since the registers datasheets for all versions of the chip
besides versions 1 - 3 are still under NDAs i had to collect
several "magical vendor constants" from the *BSD driver and the
linux driver that i was not able to name verbosely, and as such
these are labeled with the comment "vendor magic values".
We call it E1000E, because the layout for these cards is somewhat not
the same like E1000 supported cards.
Also, this card supports advanced features that are not supported on
8254x cards.
This commit initializes the LibVideo library and implements parsing
basic Matroska container files. Currently, it will only parse audio
and video tracks.
Previously, AK::Function would accept _any_ callable type, and try to
call it when called, first with the given set of arguments, then with
zero arguments, and if all of those failed, it would simply not call the
function and **return a value-constructed Out type**.
This lead to many, many, many hard to debug situations when someone
forgot a `const` in their lambda argument types, and many cases of
people taking zero arguments in their lambdas to ignore them.
This commit reworks the Function interface to not include any such
surprising behaviour, if your function instance is not callable with
the declared argument set of the Function, it can simply not be
assigned to that Function instance, end of story.
This adds a new URL parser, which aims to be compliant with the URL
specification (https://url.spec.whatwg.org/). It also contains a
rudimentary data URL parser.
Since I introduced this functionality there has been a steady stream of
people building with `ALL_THE_DEBUG_MACROS` and trying to boot the
system, and immediately hitting this assert. I have no idea why people
try to build with all the debugging enabled, but I'm tired of seeing the
bug reports about asserts we know are going to happen at this point.
So I'm hiding this value under the new ENABLE_ALL_DEBUG_FACILITIES flag
instead. This is only set by CI, and hopefully no-one will try to build
with this thing (It's documented as not recommended).
Fixes: #7527
Previously ByteBuffer::grow() behaved like Vector<T>::resize().
However the function name was somewhat ambiguous - and so this patch
updates ByteBuffer to behave more like Vector<T> by replacing grow()
with resize() and adding an ensure_capacity() method.
This also lets the user change the buffer's capacity without affecting
the size which was not previously possible.
Additionally this patch makes the capacity() method public (again).
Since this program is setuid-root, it should be as simple as possible.
To that end, remove `/etc/plsusers` and use filesystem permissions to
achieve the same thing. `/bin/pls` is now only executable by `root` or
members of the `wheel` group.
Also remove all the logic that went to great lengths to `unveil()` a
minimal set of filesystem paths that may be used for the command.
The complexity-to-benefit ratio did not seem justified, and I think
we're better off keeping this simple.
Finally, remove pledge promises the moment they are no longer needed.
These dbgln's caused excessive load in the WebServer process,
accounting for ~67% of the processing time when serving a webpage
with a bunch of resources like serenityos.org/happy/2nd/.
With the increased volume of PRs being opened and merged lately,
multiple people have complained that the IRC is absolutely flooded with
SerenityBot posts. Remove the IRC notifications from the CI scripts, and
the Meta script that handles parsing the github actions context into
an IRC message.
It seems like overly-specific classes were written for no good reason.
Instead of making each adapter to have its own unique FramebufferDevice
class, let's generalize everything to keep implementation more
consistent.
