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.
This allows us to load modules from scripts.
This can be dangerous as it can load arbitrary files. Because of that it
fails and throws by default. Currently, only js and JavaScriptTestRunner
enable the default hook.
This also adds tests to test-js which test module code. Because we
form a spec perspective can't "enter" a module this is the easiest way
to run tests without having to modify test-js to have special cases for
modules.
To specify modules in test-js we use the extension '.mjs' this is to
ensure the files are not executed. We do still want to lint these files
so the prettier scripts have changed to look for '.mjs' files as well.
This also refactors interpreter creation to follow
InitializeHostDefinedRealm, but I couldn't fit it in the title :^)
This allows us to follow the spec much more closely rather than being
completely ad-hoc with just the parse node instead of having all the
surrounding data such as the realm of the parse node.
The interpreter creation refactor creates the global execution context
once and doesn't take it off the stack. This allows LibWeb to take the
global execution context and manually handle it, following the HTML
spec. The HTML spec calls this the "realm execution context" of the
environment settings object.
It also allows us to specify the globalThis type, as it can be
different from the global object type. For example, on the web, Window
global objects use a WindowProxy global this value to enforce the same
origin policy on operations like [[GetOwnProperty]].
Finally, it allows us to directly call Program::execute in perform_eval
and perform_shadow_realm_eval as this moves
global_declaration_instantiation into Interpreter::run
(ScriptEvaluation) as per the spec.
Note that this doesn't evalulate Source Text Modules yet or refactor
the bytecode interpreter, that's work for future us :^)
This patch was originally build by Luke for the environment settings
object change but was also needed for modules. So I (davidot) have
modified it with the new completion changes and setup for that.

Length and Percentage are different types, and sometimes only one or the
other is allowed in a given CSS property. This is a first step towards
separating them.
Each ZONE entry contains a RULES segment with one of the following:
* A DST rule name, which links the ZONE to a RULE entry holding the
DST rules to apply.
* A static offset to be applied to the STDOFF offset. This implicitly
means that the time zone is in DST during that time frame.
* A "-" string, meaning no offset is applied to the STDOFF offset, and
the time zone is in standard time during that time frame.
Previously all the added icons weren't available in the online version
of the man pages. This patch adds functionality to copy all the used
icons over when assembling the HTML version.
The way that lint-ports.py obtains the ports properties is unfortunately
very process intensive. You have to execute `./package.sh showproperty`
once for each property, for each port. Resulting in hundreds of
executions.
We were doing this work twice in both `check_package_files()` and in
`read_port_dirs()`. This resulted in a runtime of around ~10 seconds on
my machine. Removing the duplicate work and allowing the other code path
to utilize the to use the cached properties brought the runtime down to
~5 seconds on my machine.
Shellcheck barfs on many of the patterns we use in port scripts, the
check is already disabled when we run the script in CI, so we might as
well disable the check for pre-commit as well.
This adds a list of ports without descriptions to filter out the
existing ports with unexplained ports, this list should *not* be
appended to!
It also adds a (for now) disabled check that ensures all ports have
patches made with (or compatible with) git.
Since the build now happens in Build/$SERENITY_ARCH/ and not in Build/,
this updates check-symbols.sh to use the correct directory to check the
LibC symbols in. For some reason, the constant failures did not show
up as errors in CI.
This change unfortunately cannot be atomically made without a single
commit changing everything.
Most of the important changes are in LibIPC/Connection.cpp,
LibIPC/ServerConnection.cpp and LibCore/LocalServer.cpp.
The notable changes are:
- IPCCompiler now generates the decode and decode_message functions such
that they take a Core::Stream::LocalSocket instead of the socket fd.
- IPC::Decoder now uses the receive_fd method of LocalSocket instead of
doing system calls directly on the fd.
- IPC::ConnectionBase and related classes now use the Stream API
functions.
- IPC::ServerConnection no longer constructs the socket itself; instead,
a convenience macro, IPC_CLIENT_CONNECTION, is used in place of
C_OBJECT and will generate a static try_create factory function for
the ServerConnection subclass. The subclass is now responsible for
passing the socket constructed in this function to its
ServerConnection base; the socket is passed as the first argument to
the constructor (as a NonnullOwnPtr<Core::Stream::LocalServer>) before
any other arguments.
- The functionality regarding taking over sockets from SystemServer has
been moved to LibIPC/SystemServerTakeover.cpp. The Core::LocalSocket
implementation of this functionality hasn't been deleted due to my
intention of removing this class in the near future and to reduce
noise on this (already quite noisy) PR.
Currently, the UnicodeLocale generator collects a list of known locales
from the CLDR before processing language display names. For each locale,
the identifier is broken into language, script, and region subtags, and
we create a list of seen languages. When processing display names, we
skip languages we hadn't seen in that first step.
This is insufficient for language display names like "en-GB", which do
not have an locale entry in the CLDR, and thus are skipped. So instead,
create the list of known languages by actually reading through the list
of languages which have a display name.
These patterns indicate how to display locale strings when that locale
contains multiple subtags. For example, "en-US" would be displayed as
"English (United States)".
Note there's a bit of an unfortunate duplication in the calendar enum
generated by UnicodeLocale and the existing enum generated by
UnicodeDateTimeFormat. The former contains every calendar known to the
CLDR, whereas the latter contains the calendars we've actually parsed
for DateTimeFormat (currently only Gregorian). The new enum generated
here can be removed once DateTimeFormat knows about all calendars.
The fuse2fs tool that is part of e2fsprogs-1.46 has a 'fakeroot'
mount option. This allows a non-root users to modify file ownership
and permissions without actually being root. This package is
available in Debian bullseye and buster-backports.
If available, the script assumes the user wants to use it.
Otherwise, it falls back to the usual root requirements.
Now that root is not required, the root check in
build-root-filesystem.sh is not necessary. Since
build-root-filesystem.sh has 'set -e' enabled, removing this check
will not cause a change in functionality.
Our generator is currently preferring the DST variant of the time zone
display names over the non-DST variant. LibTimeZone currently does not
have DST support, and operates in a mode that basically assumes DST does
not exist. Swap the display names for now just to be consistent until we
have DST support.
Note we will need to generate both of these variants and select the
appropriate one at runtime once we have DST support.
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.
Now that number systems are generated as an enum, we can generated the
number system data in the order of that enum. This lets us perform
lookups of that data by index instead of a loop of string comparisons.
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.
