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.

URL had properly named replacements for protocol(), set_protocol() and
create_with_file_protocol() already. This patch removes these function
and updates all call sites to use the functions named according to the
specification.

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.
JS::Value stores 48 bit pointers to separately allocated objects in its
payload. On x86-64, canonical addresses have their top 16 bits set to
the same value as bit 47, effectively meaning that the value has to be
sign-extended to get the pointer. AArch64, however, expects the topmost
bits to be all zeros.
This commit gates sign extension behind `#if ARCH(X86_64)`, and adds an
`#error` for unsupported architectures, so that we do not forget to
think about pointer handling when porting to a new architecture.

We were dropping the base URL path components in the resulting URL due
to mistakenly determining the input URL to start with a Windows drive
letter. Fix this, add a spec link, and a test.
A StringView is sufficient here. This also removes the declaration of
fuzzy_match_recursive from the header, as it's only needed from within
the implementation file.
LLVM 15 switched around what it's basing its `nullptr_t` definitions on,
it's now defining `std::nullptr_t` using `::nullptr_t` instead of the
other way around.
Work around any errors that result from that by just defining it both in
the global namespace as well as in `std` ourselves.
I was very confused why I was getting "no key named `foo`" errors, so
hopefully this will save someone that confusion in the future. :^)
(It'll probably be me again...)
This was present in Vector already. Clang-format fixed some const
positions automatically too.
Also removed a now-ambiguous and unnecessary constructor from Shell.
This is a set of functions that allow you to convert between arbitrary
IEEE 754 floating point types, as long as they can be represented
within 64 bits. Conversion methods between floats and doubles are
provided, as well as a generic `float_to_float()`.
Example usage:
#include <AK/FloatingPoint.h>
double val = 1.234;
auto weird_f16 =
convert_from_native_double<FloatingPointBits<0, 6, 10>>(val);
Signed and unsigned floats are supported, and both NaN and +/-Inf are
handled correctly. Values that do not fit in the target floating point
type are clamped.
Until now, our kernel has reimplemented a number of AK classes to
provide automatic internal locking:
- RefPtr
- NonnullRefPtr
- WeakPtr
- Weakable
This patch renames the Kernel classes so that they can coexist with
the original AK classes:
- RefPtr => LockRefPtr
- NonnullRefPtr => NonnullLockRefPtr
- WeakPtr => LockWeakPtr
- Weakable => LockWeakable
The goal here is to eventually get rid of the Lock* classes in favor of
using external locking.
Instead of having two separate implementations of AK::RefCounted, one
for userspace and one for kernelspace, there is now RefCounted and
AtomicRefCounted.
The commit that introduced BuiltinWrappers (548529a) accidentally used
`val` instead of `value` in the non `__GNUC__` and `__clang__` versions
of the functions.
That this did not already happen took me by surprise, as for
most other similar containers/types in AK (e.g. Span) the index
will be checked. This check not happening could easily let
off-by-one indexing errors slip through the cracks.
This can almost be identical to the Linux version, except that the
`pthread_attr_t` object is populated using a call to
`pthread_attr_get_np` instead of `pthread_getattr_np`.
FreeBSD also needs `pthread_atttr_t` to be initialized using
`pthread_attr_init` instead of zero-initialization, but it's the
technically correct thing to do on Linux as well.
This constructor relied on running strlen implicitly on its argument,
thereby potentially causing out-of-bound reads (some of which were
caught a few days ago). The removal of this constructor ensures that the
caller must explicitly pass the size of the string by either:
1) Using operator""sv on literal strings; or
2) Calling strlen explicitly, making it clear that the size of the view
is being calculated at runtime.
During the removal of StringView(char const*), all users of these
functions were removed, and they are of dubious value (relying on
implicit StringView conversion).
This prevents us from needing a sv suffix, and potentially reduces the
need to run generic code for a single character (as contains,
starts_with, ends_with etc. for a char will be just a length and
equality check).
No functional changes.
Each of these strings would previously rely on StringView's char const*
constructor overload, which would call __builtin_strlen on the string.
Since we now have operator ""sv, we can replace these with much simpler
versions. This opens the door to being able to remove
StringView(char const*).
No functional changes.
Error::from_string_literal now takes direct char const*s, while
Error::from_string_view does what Error::from_string_literal used to do:
taking StringViews. This change will remove the need to insert `sv`
after error strings when returning string literal errors once
StringView(char const*) is removed.
No functional changes.
This commit moves the length calculations out to be directly on the
StringView users. This is an important step towards the goal of removing
StringView(char const*), as it moves the responsibility of calculating
the size of the string to the user of the StringView (which will prevent
naive uses causing OOB access).
