This script will instantiate a HackStudio template into a project on the
host. It currently supports all templates used by HackStudio.
To avoid having to maintain compatibility between other shells and the
Serenity shell in the postcreate scripts, we build the Serenity shell
with Lagom and use that to run the script.

Having lots of small files in Base/ may require more inodes in the
ext2 filesystem than the format utility sets aside by default. Let's
make a more educated guess since we have a rough idea of how many
inodes we need by counting files and directories.

This probably isn't all of them, because I'm no CMake expert. :^)
It does however allow "/bin/false" to build now.

This contains all the bits and pieces necessary to build a Clang binary
that will correctly compile SerenityOS.
I had some trouble with getting LLVM building with a single command, so
for now, I decided to build each LLVM component in a separate command
invocation. In the future, we can also make the main llvm build step
architecture-independent, but that would come with extra work to make
library and include paths work.
The binutils build invocation and related boilerplate is duplicated
because we only use `objdump` from GNU binutils in the Clang toolchain,
so most features can be disabled.

This seemed like a good idea at the time to avoid an unnecessary
dependency on qemu-system-i386. However this makes debugging the
kernel with GDB more difficult because GDB assumes that the QEMU
architectures matches the kernel architecture.

Before Libraries was moved to Userland/Libraries syslog.h had a bunch
of manually aligned defines and array initializations.
Andreas seems to have formatted the file with clang-format as part of
that file move. Since syslog.h is now properly formatted, we don't
need to exclude it from the linter list.

This commit implements the ISO 9660 filesystem as specified in ECMA 119.
Currently, it only supports the base specification and Joliet or Rock
Ridge support is not present. The filesystem will normalize all
filenames to be lowercase (same as Linux).
The filesystem can be mounted directly from a file. Loop devices are
currently not supported by SerenityOS.
Special thanks to Lubrsi for testing on real hardware and providing
profiling help.

As this is a test machine I use personally to test "modern" hardware
setups, it feels quite comfortable to not care too much about VGA with
this type of machine.
Also, we don't actively use the IDE controller on this machine type, so
let's just remove it :^)

This allows one to set their desired parameters for run.sh without the
need to set them in every terminal session or add it to the user account
shell files. If a run-local.sh file exists at the repository root and is
executable, it will be sourced. The file can contain any variables that
are expected to be set in run.sh.

This allows running QEMU inside WSL2 for hosts which have nested KVM
and WSLg support (e.g. Windows 11).
Running QEMU inside the WSL2 VM is slightly slower than running QEMU
on Windows, probably because of how WSLg handles screen updates.

Although it is nice to test the system without too many devices, in
reality bare metal hardware is far more complex than the default skeleon
that QEMU provides. As a preparation of supporting more devices, we
need to ensure we are capable of at least booting on complex hardware
setups without easily-observable problems. Later on, this can be the
foundations of testing new drivers :^)

Some users might not have qemu-system-i386 installed.
|
|
This gets rid of the following warning message from QEMU on startup:
qemu-system-i386: warning: '-soundhw pcspk' is deprecated, please set a
backend using '-machine pcspk-audiodev=<name>' instead
Fixes #4093.
|
|
For users who use a custom kernel with WSL our previous method of
detecting WSL doesn't work. This new check instead detects WSL by
checking if the wslpath utility is available.

This standard CMake option controls whether add_library() calls will
use STATIC or SHARED by default. The flag is set to on by default
since that's what we want for normal CI jobs and local builds and the
test262 runner, but disabled for oss-fuzz builds.
This should finally fix the oss-fuzz build after it was broken in #9017
oss-fuzz un-breakage was verified by running the following commands in
the oss-fuzz repo:
python infra/helper.py build_image serenity
python infra/helper.py build_fuzzers --sanitizer address --engine afl \
--architecture x86_64 serenity /path/to/local/checkout/Meta/Lagom
python infra/helper.py check_build --sanitizer address --engine afl \
--architecture x86_64 serenity

Otherwise we're getting this warning:
WARNING: Image format was not specified for '_disk_image' and probing
guessed raw. Automatically detecting the format is dangerous
for raw images, write operations on block 0 will be restricted.
Specify the 'raw' format explicitly to remove the restrictions.

QEMU 5 doesn't support -machine pcspk-audiodev so we need to fall back
to using -soundhw for that.
|
|
You can now turn debug logging for them on using `CSS_PARSER_DEBUG` and
`CSS_TOKENIZER_DEBUG`.
|
|
This fixes audio on Windows as well as Linux systems which don't have
SDL.
Fixes #8903.
|
|
Previously we'd fall back to using cp if rsync wasn't available. Not
only is this considerably slower it also breaks when some of the files
in the target directory are symlinks because cp tries to dereference
them.
Fixes #8672.

This supports some binary property matching. It does not support any
properties not yet parsed by LibUnicode, nor does it support value
matching (such as Script_Extensions=Latin).
|
|
The OSS-Fuzz build was failing with the following error:
/usr/bin/ld: cannot find -l{}

Create the proper export files to allow Lagom to be a well-behaved
ExternalProject, based on the example project from the cmake-init
project generator here:
https://github.com/friendlyanon/cmake-init-shared-static
|

Split the Lagom build into shared libraries to match the Serenity build.
This reduces the cognitive load when trying to edit the Lagom CMakeLists
significantly. It also reduces the amount of source files that must be
compiled to run each test or host program significantly.
Also re-organize all the build rules into sections. And reorganize the
CMakeLists file in general.
|
|
By using the power of object libraries and $<TARGET_OBJECTS> we can make
sure to only build TestMain.cpp and JavaScriptTestRunnerMain.cpp once.
Previously we built these cpp files into object files once for every
single test executable. This change reduces the number of total compile
jobs in a Serenity target build by around 100.

LibTTF has a concrete dependency on LibGfx for things like Gfx::Bitmap,
and LibGfx has a concrete dependency in the TTF::Font class in
Gfx::FontDatabase. This circular dependency works fine for Serenity and
Lagom Linux builds of the two libraries. It also works fine for static
library builds on Lagom macOS builds.
However, future changes will make Lagom use shared libraries, and
circular library dependencies are not tolerated in macOS.

You can now see the outline of GUI widgets when hovering them.
For example:
$ export GUI_HOVER_DEBUG=1
$ FileManager
Then move the mouse around in the file manager. :^)

I have set up a commit.verbose variable in my git config,
which shows the patch diff on bottom of the commit message.
Unfortunately the character limit was also applied to the diff,
which meant that I got a false-positive lint error almost every time.
|
|
This was missing 2 of the recently added checks. Also added a reminder
in the CI linter to update the Meta (commit hook) version.
|
|
Unfortunately seems like QEMU tries to use SPICE for audio so we need to
explicitly set -audiodev to use either SDL or coreaudio (depending on
platorm)
|
|
This enables further work on implementing KASLR by adding relocation
support to the pre-kernel and updating the kernel to be less dependent
on specific virtual memory layouts.
|
|
This is primarily to allow using LibUnicode within LibJS and its REPL.
Note: this seems to be the first time that a Lagom dependency requires
generated source files. For this to work, some of Lagom's CMakeLists.txt
commands needed to be re-organized to include the CMake files that fetch
and parse UnicodeData.txt. The paths required to invoke the generator
also differ depending on what is currently building (SerenityOS vs.
Lagom as part of the Serenity build vs. a standalone Lagom build).
|
|
Instead, just make QEMU quit immediately.
|
|
You can set the SERENITY_ETHERNET_DEVICE_TYPE environment variable to
pick another device type (i.e. ne2k_pci). Defaults to e1000 as before.

This thing seems to work fine, no need to hang on to old debug code.
|
|
This allows testing the extlinux image with QEMU.
