This sets up the generator plumbing to create the relative-time data
files. This data could probably be included in the date-time generator,
but that generator is large enough that I'd rather put this tangentially
related data in its own file.
This check isn't needed because download_file() will check if it exists
already before doing the download. Worse, it would prevent the generator
target from being defined if the file existed, which then made CMake not
realize the generated files were important and delete them.
After fixing the CMake file to use the correct paths, users may have had
to manually remove the existing downloaded pnp.ids.html for CMake to re-
run the generator. So this change renames the downloaded file to
pnp_ids.html to ensure everyone picks up that change without manual
intervention.
Code generators that generate their files for both Lagom and Serenity
have a blob in their CMake file like this:
set(TIME_ZONE_DATA_HEADER LibTimeZone/TimeZoneData.h)
set(TIME_ZONE_DATA_IMPLEMENTATION LibTimeZone/TimeZoneData.cpp)
set(TIME_ZONE_META_TARGET_PREFIX LibTimeZone_)
if (CMAKE_CURRENT_BINARY_DIR MATCHES ".*/LibTimeZone")
# Serenity build.
set(TIME_ZONE_DATA_HEADER TimeZoneData.h)
set(TIME_ZONE_DATA_IMPLEMENTATION TimeZoneData.cpp)
set(TIME_ZONE_META_TARGET_PREFIX "")
endif()
LibEDID generates files only for Serenity, but was using the Lagom build
version of the _HEADER, _IMPLEMENTATION, and _PREFIX variables. Thus if
pnp_ids.cmake was ever touched, the following error would be raised:
Userland/Libraries/LibEDID/EDID.cpp:18:18: fatal error:
LibEDID/PnpIDs.h: No such file or directory
18 | # include <LibEDID/LibEDID/PnpIDs.h>
Use the Serenity paths in pnp_ids.cmake and in the #include within
LibEDID itself.
This function will handle download failures. It doesn't support hashing
for integrity yet, but if the download times out or otherwise fails, the
build itself will fail. But default, file(DOWNLOAD) in CMake doesn't
fail the build; we must pass in and check a STATUS variable.
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.

This downloads the UEFI's published PNP ID database and generates a
lookup table for use in LibEDID. The lookup table isn't optimized at
all, but this can be easily done at a later point if needed.
vdbgln() was responsible for ~10% of samples on pv's flamegraph for
RequestServer (under request_did_finish) when loading github.com in
Browser and recording a whole-system profile. This makes that almost
completely disappear.
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.
We had a hard-coded table of number system digits copied from ECMA-402.
Turns out these digits are in the CLDR, so let's parse the digits from
there instead of hard-coding them.
The IANA Time Zone Database contains data needed, at least, for various
JavaScript objects. This adds plumbing for a parser and code generator
for this data. The generated data will be made available by LibTimeZone,
much like how UCD and CLDR data is available through LibUnicode.
This function will be used by the time zone database parser. Move it to
the common utilities file, and rename it remove_path_if_version_changed
to be more generic.
Add a basic NVMe driver support to serenity
based on NVMe spec 1.4.
The driver can support multiple NVMe drives (subsystems).
But in a NVMe drive, the driver can support one controller
with multiple namespaces.
Each core will get a separate NVMe Queue.
As the system lacks MSI support, PIN based interrupts are
used for IO.
Tested the NVMe support by replacing IDE driver
with the NVMe driver :^)
Unlike most data in the CLDR, hour cycles are not stored on a per-locale
basis. Instead, they are keyed by a string that is usually a region, but
sometimes is a locale. Therefore, given a locale, to determine the hour
cycles for that locale, we:
1. Check if the locale itself is assigned hour cycles.
2. If the locale has a region, check if that region is assigned hour
cycles.
3. Otherwise, maximize that locale, and if the maximized locale has
a region, check if that region is assigned hour cycles.
4. If the above all fail, fallback to the "001" region.
Further, each locale's default hour cycle is the first assigned hour
cycle.
Similar to number formatting, the data for date-time formatting will be
located in its own generated file. This extracts the cldr-dates package
from the CLDR and sets up the generator plumbing to create the date-time
data files.
The serenity_install_sources function now infers the path under
`/usr/src/serenity` in which to install the source files according to
the relative path of the source files in the repository.
For example `Userland/Libraries/LibGUI/Widget.h` gets installed at
`/usr/src/serenity/Userland/Libraries/LibGUI/Widget.h`.
This fixes cases where the source files of libraries are not under
`Userland/Libraries` (for example LibShell & LibLanguageServer).
For example, there isn't a unique set of data for the en-US locale;
rather, it defaults to the data for the en locale. See this commit for
much more detail: 357c97dfa8
libc++ uses a Pthread condition variable in one of its initialization
functions. This means that Pthread forwarding has to be set up in LibC
before libc++ can be initialized. Also, because LibPthread is written in
C++, (at least some) parts of the C++ standard library have to be linked
against it.
This is a circular dependency, which means that the order in which these
two libraries' initialization functions are called is undefined. In some
cases, libc++ will come first, which will then trigger an assert due to
the missing Pthread forwarding.
This issue isn't necessarily unique to LibPthread, as all libraries that
libc++ depends on exhibit the same circular dependency issue.
The reason why this issue didn't affect the GNU toolchain is that
libstdc++ is always linked statically. If we were to change that, I
believe that we would run into the same issue.
This allows libraries and binaries to explicitly link against
`<library>.so.serenity`, which avoids some confusion if there are other
libraries with the same name, such as OpenSSL's `libcrypto`.
This commit updates the Clang toolchain's version to 13.0.0, which comes
with better C++20 support and improved handling of new features by
clang-format. Due to the newly enabled `-Bsymbolic-functions` flag, our
Clang binaries will only be 2-4% slower than if we dynamically linked
them, but we save hundreds of megabytes of disk space.
The `BuildClang.sh` script has been reworked to build the entire
toolchain in just three steps: one for the compiler, one for GNU
binutils, and one for the runtime libraries. This reduces the complexity
of the build script, and will allow us to modify the CI configuration to
only rebuild the libraries when our libc headers change.
Most of the compile flags have been moved out to a separate CMake cache
file, similarly to how the Android and Fuchsia toolchains are
implemented within the LLVM repo. This provides a nicer interface than
the heaps of command-line arguments.
We no longer build separate toolchains for each architecture, as the
same Clang binary can compile code for multiple targets.
The horrible mess that `SERENITY_CLANG_ARCH` was, has been removed in
this commit. Clang happily accepts an `i686-pc-serenity` target triple,
which matches what our GCC toolchain accepts.
Until we're confident that RequestServer doesn't need this runtime debug
dump helper, it's much nicer if everyone has it built in, so they can
simply send a SIGINFO if they see it acting up.
