This matches how LibMain is used within Serenity. This commit makes it
possible to build Lagom with LTO. Previously, `serenity_main` functions
would be dead-stripped away, as the linker could prove that nothing from
the executable ever called them.
This is the initial port of Lagom to win32. This will enable developers
to use Lagom as an alternative to vanilla STL/StandardC++Library - which
gives a much richer environment (think QtCore - but modern).
My main incentive - is to have a native Windows Ladybird working.
I am starting with AK, which does not yet fully compile (on mingw). When
AK is compiling (currently fails building StringBuffer.cpp) - I will
continue to LibCore and then the rest of the user space libraries
(excluding the GUI, which will be another different effort).
Most of the code is happily stollen from Andrew Kaster's fork - he
deserves the credit.

Some time zones, like "Asia/Shanghai", use a set of DST rules that end
before present day. In these cases, we should fall back to last possible
RULE entry from the TZDB. The time zone compiler published by IANA (zic)
performs the same fallback starting with version 2 of the time zone file
format.
IDL dictionary members are nullable by default (unless marked as
`required`) and should not get any value assigned unless one was
provided by the userland code that isn't undefined, or if the member has
a default value.
This is so that we can use Optional<T> in the internal representation
and check for "is present" via Optional::has_value().
The SourceGenerator's @else@ mapping is only set in the second iteration
of the loop, causing the generated return for unrecognized values to not
be guarded by an else statement.
We can simply use a hardcoded 'else' here, @else@ is only to create the
first comparison as a plain 'if' and subsequent ones as 'else if'.
Without this, the generated DOMExceptionConstructor does not refer to
the WebIDL::DOMException with its fully qualified name. This caused an
ambiguity error on my machine.
Let's stop putting generic types and AOs from the Web IDL spec into
the Bindings namespace and directory in LibWeb, and instead follow our
usual naming rules of 'directory = namespace = spec name'. The IDL
namespace is already used by LibIDL, so Web::WebIDL seems like a good
choice.
SafeFunction automatically registers its closure memory area in a place
where the JS garbage collector can find it.
This means that you can capture JS::Value and arbitrary pointers into
the GC heap in closures, as long as you're using a SafeFunction, and the
GC will not zap those values!
There's probably some performance impact from this, and there's a lot of
things that could be nicer/smarter about it, but let's build something
that ensures safety first, and we can worry about performance later. :^)
We won't be able to use local servers on Android without some serious
Android work to create background tasks, so just disable this for now,
as it currently relies on Core::Account to take over from SystemServer.
Some systems don't have /usr/bin/time available, and during most runs
of lint-ci we don't actually care that much about the exact timing.
Therefore, let's just remove it. It's easy enough to add back in, if
someone wants to investigate an issue.
This code generator no longer creates JS wrappers for platform objects
in the old sense, instead they're JS objects internally themselves.
Most of what we generate now are prototypes - which can be seen as
bindings for the internal C++ methods implementing getters, setters, and
methods - as well as object constructors, i.e. bindings for the internal
create_with_global_object() method.
Also tweak the naming of various CMake glue code existing around this.
This name more accurately reflects what we are checking. Also add an
explanatory note that only a hand-curated subset of platform object
types is checked in the absence of a full generated list.
With this device being added, we can now boot into graphics mode on
these platforms too. For ISA-PC machine this is basically the only
viable option to use, but in the future, we should remove this device
for the microvm machine type as it should allow us to determine better
options and detect them by using a given device tree blob.
I totally overlooked that /usr/bin/time is not universal, which broke
some systems. This commit instead calls 'time', allowing either a shell
built-in to kick in, or a (potentially different) binary be found
anywhere in the PATH.
This speeds up the script from about 90ms down to about 10ms, for
reasonably common changesets.
80ms may not feel like much, but it adds up quickly, especially since
we run a dozen scripts during pre-commit.
This speeds up the script from about 140ms down to <10ms, even for
changesets that touch a handful of different GML files.
130ms may not feel like much, but it adds up quickly, especially since
we run a dozen scripts during pre-commit.
This speeds up the script from about 120ms down to about 20ms for
reasonably common changesets.
100ms may not feel like much, but it adds up quickly, especially since
we run a dozen scripts during pre-commit.
This speeds up the script from about 170ms down to about 80ms for
changes in Debug.h.in or similarly "DEBUG"-rich files, down to <10ms for
more common changesets.
160ms may not feel like much, but it adds up quickly, especially since
we run a dozen scripts during pre-commit.
This fixes an issue on Twitter where they were instantiating an
IntersectionObserver with a null root. The root IDL type is
`(Element or Document)?` so null needs to be allowed.
Rather than invoking AK::Time::from_timestamp at runtime, we can do so
at compile time. This reduces invoking TimeZone::get_time_zone_offset
100,000 times in a loop from about 7 seconds to 30 milliseconds.
