This command copies the project's source tree to
/home/anon/Source/serenity in the built disk image.
This will be useful for working on serenity inside serenity :^)
|
|
The on-target pipelines have a timeout of 6 hours to allow time for a
clean toolchain + Serenity build. Tests should time out much sooner than
that though.

Caches on Azure are immutable - so if a cache changes, but its key does
not, then the cache is not updated. Include a timestamp in the ccache
key so that we always push an updated cache from the master branch. Then
use a subkey without the timestamp to pull the cache.
We use a similar trick on GitHub Actions.

Previously debug-kernel.sh wouldn't detect source if you launched the
script from the wrong path. By explicitly setting the name, source will
be loaded by gdb in all situations.

We want to use use the 'du' option '--apparent-size' which is a
GNU coreutils extension. GNU coreutils is a build dependency so
we know it is available. With this commit we first try to pick up
du as 'gdu', and if that fails, try 'du' instead.

There was previously a case where the build-image-qemu.sh script
decided to mount an existing disk image, but without creating the
memory disk device and recording its /dev file name.
After this commit, We create the memory disk device just before
it is used to mount the disk image.
|
|
We were over-hashing for the GNU build on GitHub Actions by including
the LLVM patch as well. The GNU Toolchain doesn't care about our LLVM
patches.
For Azure, fix the inversion of the condition for which jobs check which
Build*.sh script, and add the Toolchain patch files to the cache
hash calculation.

Adds a compiler cache and a cache for the UCD files.
|
|
The top-level CMakeLists.txt already automatically detects ccache, but
CI will invoke CMake with Lagom's CMakeLists.txt. Add an option to Lagom
to do the same detection.

The function arguments almost always optimized away, so you never get
much value out of showing these in the default back trace view, it just
adds a bunch of extra stuff that you need to visual wade through.
So lets disable showing them.

Similarly to the LibCpp parser regression tests, these tests run the
preprocessor on the .cpp test files under
Userland/LibCpp/Tests/preprocessor, and compare the output with existing
.txt ground truth files.

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.
