The install() command used by 1e36d5449304226b097a4929a90f846c0ddf1d76
installs the provided file into the *directory* named by the DESTINATION
parameter. So if we ask it to install pci.ids to /res/pci.ids, the final
destination will be /res/pci.ids/pci.ids.
|
|
`file(COPY_FILE ...)` fails if the target directory does not already
exist, whereas `install(FILES ... DESTINATION ...)` happily creates all
the required directories.
|
|
This ensures we only need to download these files once for all build
configurations. We similarly download the UCD, CLDR, and TZDB to this
cache directory as well.

"image" was an alias for "qemu-image".
I want to add an `image` userland utility, which clashes with that
shortname.
So remove the existing "image" target. It was just an alias for
"qemu-image".
If you use serenity.sh to build, nothing changes. This only affects you
if you run ninja manually -- you now have to say `ninja qemu-image` to
build the disk image.

Clean up the Wasm spec tests CMake rules to extract and compile the wat
files into wasm files in the LibWasm binary directory instead of its
source directory. Also make the rules more robust to missing host tools,
and use more CMake install rules for the test files rather than relying
on build-root-filesystem.sh. Add some FIXMEs for later, we really
shouldn't be doing installation of test files into /home/anon at the
build-root-filesystem stage in $CURRENT_YEAR. Tests go in /usr/Tests

Tell CMake to not create a new policy scope for the
(lagom|serenity|common)_options.cmake helpers, and lets us set common
policies for both projects in common_options.cmake that actually apply
to the rest of the project, instead of just common_options.cmake itself.

The SerenityOS platform files we upstreamed were first released in
version 3.25.0

Surely this will just work once the kernel boots, right?
|
|
By default char and wchar_t are unsigned on AARCH64. This fixes a
bunch of related compiler errors.
|
|
Both USB_IDS_PATH and PCI_IDS_PATH are now unused so can be safely
removed.

Problem: cmake cannot handle gzip files (see
https://gitlab.kitware.com/cmake/cmake/-/issues/23054 for more
details).
Instead of downloading the compressed (*.gz) USB and PCI ids,
we not download the raw uncompressed files. The sizes we "loose"
due to downloading such files are meaningless.
This are the file sizes:
```
diego@debian:~/$ ls -lh pci.ids{,.gz} usb.ids{,.gz}
-rw-r--r-- 1 diego diego 1.3M Aug 7 04:15 pci.ids
-rw-r--r-- 1 diego diego 300K Aug 7 04:15 pci.ids.gz
-rw-r--r-- 1 diego diego 700K May 20 22:34 usb.ids
-rw-r--r-- 1 diego diego 245K May 20 22:34 usb.ids.gz
```

Newer cmake's have internal functions to un-compress files. These
functions will work on pure windows - as well as linux. This
eliminates the need to search for external tools (TAR,GZIP,ZIP) - and
helps fixing #9866.
In order to finally fix #9866 we need to decide to bump the cmake
version requirements and remove the checks. If we demand a newer cmake
version, we will loose Ubuntu 20.04 as a build target - as it ships
with CMake 3.16.
For now - we keep compatibility with CMake 3.16 - and only if CMake
3.18 as been found - we use its new functionality.

Remove the Corrosion dependency, and use the now-builtin
add_jakt_executable function from the Jakt install rules to build our
example application.
By using find_package(Jakt), we now have to set ENABLE_JAKT manually on
both serenity and Lagom at the same time, so the preferred method to do
this for now is:
cmake -B Build/superbuild<arch><toolchain> \
-S Meta/CMake/Superbuild \
-DENABLE_JAKT=ON \
-DJAKT_SOURCE_DIR=/path/to/jakt
Where omitting JAKT_SOURCE_DIR will still pull from the main branch of
SerenityOS/jakt. This can be done after runing Meta/serenity.sh run.

The FLAC "spec tests", or rather the test suite by xiph that exercises
weird FLAC features and edge cases, can be found at
https://github.com/ietf-wg-cellar/flac-test-files and is a good
challenge for our FLAC decoder to become more spec compliant. Running
these tests is similar to LibWasm spec tests, you need to pass
INCLUDE_FLAC_SPEC_TESTS to CMake.
As of integrating these tests, 23 out of 63 fail. :yakplus:

Building might fail if the cmake command path contains
whitespace. See https://stackoverflow.com/a/35853080.

The current emoji_txt.cmake does not handle download errors (which were
a common source of issues in the build problems channel) or Unicode
versioning. These are both handled by unicode_data.cmake. Move the
download to unicode_data.cmake so that we can more easily handle next
month's Unicode 15 release.
|
|
Instead of manually updating emoji.txt whenever new emoji are added,
we use Unicode's emoji-test.txt to generate emoji.txt on each build,
including only the emojis that Serenity supports at that time.
By using emoji-test.txt, we can also include all forms of each emoji
(fully-qualified, minimally-qualified, and unqualified) which can be
helpful when double-checking how certain forms are handled.
|
|
Not sure why that happens and how it worked until now, but we need to be
more precise about the location of PCI and USB IDs when decompressing
them while building the OS.

In commit 02e8f2956014bd17c4e5a68757776fffc6d43c51 we started exporting
the `CMAKE_INSTALL_*DIR` variables without prefix in order to make
better use of the actual `PREFIX` settings.
However, commands like `file(MAKE_DIRECTORY ...)` don't understand the
GNUInstallDirs way of building paths, so we ended up creating
directories in our main project directory by accident.
Fix that by manually adding the correct prefix onto the path.
|
|
In preparation for future refactoring of Lagom, let's use the variables
from GNUInstallDirs as much as possible for the helper macros and other
scripts used by the main build already.
|
|
We can now use ENABLE_JAKT to pull jakt as a host tool and use it to
pre-process .jakt files into .cpp files for use in serenity applications
|
|
This way we can have all of them in a single place, similar to how we
structure options added via the serenity_option() macro.
|
|
This release brings support for various C++23 constructs like `if
consteval` and multidimensional subscript operators. Vectorization is
now enabled for O2 too, and `-ftrivial-auto-var-init` has been added
which can help us find and prevent security issues coming from
uninitialized variables.
Toolchain/Patches/gcc.patch is now significanly smaller as some unused,
autoconf-generated code has been removed.
|
|
Ports like SDL2 can depend on headers that try to include `Debug.h`.
|
|
Besides a version bump, the following changes have been made to our
toolchain infrastructure:
- LLVM/Clang is now built with -march=native if the host compiler
supports it. An exception to this is CI, as the toolchain cache is
shared among many different machines there.
- The LLVM tarball is not re-extracted if the hash of the applied
patches doesn't differ.
- The patches have been split up into atomic chunks.
- Port-specific patches have been integrated into the main patches,
which will aid in the work towards self-hosting.
- <sysroot>/usr/local/lib is now appended to the linker's search path by
default.
- --pack-dyn-relocs=relr is appended to the linker command line by
default, meaning ports take advantage of RELR relocations without any
patches or additional compiler flags.
The formatting of LLVM port's package.sh has been bothering me, so I
also indented the arguments to the CMake invocation.

We have seen some cases where the build fails for folks, and they are
missing unzip/tar/gzip etc. We can catch some of these in CMake itself,
so lets make sure to handle that uniformly across the build system.
The REQUIRED flag to `find_program` was only added on in CMake 3.18 and
above, so we can't rely on that to actually halt the program execution.

With regular builds, the generated IPC headers exist inside the Build
directory. The path Userland/Services under the build directory is
added to the include path.
For in-system builds the IPC headers are installed at /usr/include/.
To support this, we add /usr/include/Userland/Services to the build path
when building from Hack Studio.

This variable was originally called USE_MOLD_LINKER, but it was changed
to ENABLE_MOLD_LINKER during review to be consistent with other
configuration options. I branched off the commits that added RELR
support before this change, and I failed to update the variable name
there.

Also add a check to serenity.sh to ensure that the toolchain is new
enough for this feature to work.

While playing around with getting serenity to run on my main desktop
machine I wanted a way of easily updating my physical serenity
partition.
To use it you just need to:
- Create and format your local partition to ext4
- Set `SERENITY_TARGET_INSTALL_PARTITION` to the partition /dev path.
- Run the `install-native-partition` build target.
Example:
$ export SERENITY_TARGET_INSTALL_PARTITION=/dev/nvme1n1p3
$ cd serenity/Build/x86_64
$ ninja install-native-partition

This commit adds support for building the SerenityOS userland with the
new [mold linker].
This is not enabled by default yet; to link using mold, run the
`Toolchain/BuildMold.sh` script to build the latest release of mold, and
set the `ENABLE_MOLD_LINKER` CMake variable to ON. This option relies on
toolchain support that has been added just recently, so you might need
to rebuild your toolchain for mold to work.
[mold linker]: https://github.com/rui314/mold
|
|
If this option is set, we will not build all components.
Instead, we include an external CMake file passed in via a variable
named HACKSTUDIO_BUILD_CMAKE_FILE.
This will be used to build serenity components from Hack Studio.

The `--allow-shlib-undefined` option is a bit of a misnomer. It actually
controls whether we should be allowed to have undefined references after
symbols from all dependencies have been resolved, so it applies both to
shared libraries and executables.
LLD defaults to allowing undefined references in shared libraries, but
not in executables. Previously, we had to disable this check for
executables too, as it caused a build failure due to the
LibC-LibPthread-libc++ and the LibCore-LibCrypto circular dependencies.
Now that those have been resolved, we can enable this warning, in the
hopes that it will prevent us from introducing circular libraries and
missing dependencies that might cause unexpected breakage.

At some point we probably needed these, but no code complains about them
with the current state of the codebase.
|
|
These two helpers were the only unused functions clang could detect in
the entire codebase. Now that's commitment to no dead code :^)
|
|
These are almost always bugs, so enable globally.
Remove unused counter variables in SystemMonitor and disk_benchmark.
|
|
Stop comparing platform-specific sized integer types to max() values of
other interger types. Enable the warning everywhere.
|
|
There's only two places where we're using the C99 feature of array
designated initalizers. This feature seemingly wasn't included with
C++20 designated initalizers for classes and structs. The only two
places we were using this feature are suitably old and isolated that
it makes sense to just suppress the warning at the usage sites while
discouraging future array designated intializers in new code.
|
|
Enable the warning project-wide. It catches when a non-virtual method
creates an overload set with a virtual method. This might cause
surprising overload resolution depending on how the method is invoked.
|
|
The Clang implementation of this warning protects against some undefined
pre-processor behavior while ignoring function-like macros. The gcc
implementation also warns on function-like macros, and is therefore
noisy.
|
|
These were removed in the Superbuild conversion. Re-add the checks that
make sure that if there's a toolchain update, developers re-build their
toolchain.
