This fixes `combine_hangul_code_points` which would try to combine
a LVT syllable with a trailing consonant, resulting in a wrong
character.
Also added a test for this specific case.

`mkstemps` generates a unique temporary file name from a pattern like
`prefixXXXXXXsuffix` where `prefix` and `suffix` can be any string with
only characters that are valid in a filename. The second parameter is
the length of the suffix.
`mkstemp` is `mkstemps` with suffix length 0, so to avoid code
duplication it calls `mkstemps`. It is unlikely this has any
significant performance impact on SerenityOS.
`generate_unique_filename` now takes the suffix length as a `size_t`.
The original behavior of this function is preserved when specifying a
suffix length of 0. All original uses of this function have been
adapted.
`mkstemps()` was added because it is required by version 4.6.3 of the
ccache port.

Doesn't use them in libc headers so that those don't have to pull in
AK/Platform.h.
AK_COMPILER_GCC is set _only_ for gcc, not for clang too. (__GNUC__ is
defined in clang builds as well.) Using AK_COMPILER_GCC simplifies
things some.
AK_COMPILER_CLANG isn't as much of a win, other than that it's
consistent with AK_COMPILER_GCC.

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.

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.
Fixes #15290
Fixes SerenityOS/ladybird#56

x86 IO space is not relevant for non-x86 builds so it doesn't make sense
to include it in such build as it will not compile anyway.

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.
|
|
The test-case is heavily inspired by:
https://github.com/google/brotli/blob/master/tests/testdata/x.compressed.01
Or in words: A metadata meta-block containing `Y` (which should be
ignored), and then the actual data (a single `Z`). The bug used to skip
one metadata byte too few, and thus read garbage.

Propagate errors in places that are already set up to handle them, like
WebGLRenderingContext and the Tubes demo, and convert other callers
to using MUST.

This caused the m_allocation_enabled_previously member to be technically
uninitialized when the compiler emits the implicit destructor call for
stack allocated classes.
This was pointed out by gcc on lagom builds, no clue how this was flying
under the radar for so long and is not triggering CI.
|
|
Spelling fixes found by `codespell`.

...`__attribute__((__noreturn__))`
This is more inline with the definition in glibc's version of the file,
and stops clang from complaining about it originally not being declared
as `[[no_return]]`.

Each texture unit now has its own texture transformation matrix stack.
Introduce a new texture unit configuration that is synced when changed.
Because we're no longer passing a silly `Vector` when drawing each
primitive, this results in a slightly improved frames per second :^)

This allows running of test262 (like) tests with any runner. And thus
allows running the full test262 suite on Serenity itself.
The functionality of test-test262 is intentionally limited at first.
It does support:
- Progress updates including the special serenity terminal commands
- Outputting a per-file, to compare against other runs
- Passing any number of parameters to the runner
- Setting the batch size of the amount of tests per runner process
- Outputting a summary of the test results
|
|
If a test is supposed to fail during parse or early phase we can stop
after parsing. Because phases in modules are not as clear we don't skip
the other parts for modules.
|
|
Since this application is now supposed to be used from within Serenity
we should make sure to warn the actual user.
|
|
When running a larger set of tests in Serenity the runner would
otherwise trigger a lot of crash reporters. This would then in turn lead
to memory starvation causes more crashes.
|
|
This makes it easier to use the runner directly.
|
|
We also protect against recursive assert failures, for example due to
being out of memory.
With this change the runner now compiles and runs on Serenity :^).
|
|
This was shadowing a name in LibC triggering warnings.
|
|
Since setitimer is not implemented in Serenity we use alarm which
triggers SIGALRM after the timeout. We also don't use a signal handler
as we are doing things that serenity doesn't like/doesn't allow.
Linux dealt with allocating and writing in a signal handler but it is
undefined, so instead we just let the process die by SIGALRM.
This means we instead of reading the output can detect timeouts by
checking how the process died.
|
|
For now this is a lagom only application as it is not compatible with
serenity in its current state.
The only change is that it is released under a different license with
permission from all the authors.
|
|
Also ensure that all a nullptr input gives null object and you don't
accidentally dereference a nullptr.
|
|
We were consuming all whitespace from the format, but not the input
lexer - that was left to the actual format parsing code. It so happened
that we did not account for whitespace with the conversion specifier
'[', causing whitespace to end up in the output variables.
Fix this by always consuming all whitespace and removing the whitespace
logic from the conversion code.

Everything is now setup to create the LibLocale library and link it
where needed.
|
|
|
|
These are still included in LibUnicode, but this updates their location
and the include paths of other files which include them.
|
|
|
|
Currently, LibUnicodeData contains the generated UCD and CLDR data. Move
the UCD data to the main LibUnicode library, and rename LibUnicodeData
to LibLocaleData. This is another prepatory change to migrate to
LibLocale.

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:
|
|
This is required for ECMA-404 compliance, but probably not for serenity
itself.

Previously, for a regex such as /[a-sy-z]/i, we would incorrectly think
the character "u" fell into the range "a-s" because neither of the
conditions "u > s && U > s" or "u < a && U < a" would be true, resulting
in the lookup falling back to assuming the character is in the range.
Instead, first explicitly check if the character falls into the range,
rather than checking if it falls outside the range. If the explicit
checks fail, then we know the character is outside the range.

Intrinsics, i.e. mostly constructor and prototype objects, but also
things like empty and new object shape now live on a new heap-allocated
JS::Intrinsics object, thus completing the long journey of taking all
the magic away from the global object.
This represents the Realm's [[Intrinsics]] slot in the spec and matches
its existing [[GlobalObject]] / [[GlobalEnv]] slots in terms of
architecture.
In the majority of cases it should now be possibly to fully allocate a
regular object without the global object existing, and in fact that's
what we do now - the realm is allocated before the global object, and
the intrinsics between both :^)

In OpenGL this is called the (base) internal format which is an
expectation expressed by the client for the minimum supported texel
storage format in the GPU for textures.
Since we store everything as RGBA in a `FloatVector4`, the only thing
we do in this patch is remember the expected internal format, and when
we write new texels we fixate the value for the alpha channel to 1 for
two formats that require it.
`PixelConverter` has learned how to transform pixels during transfer to
support this.
|
|
A GPU (driver) is now responsible for reading and writing pixels from
and to user data. The client (LibGL) is responsible for specifying how
the user data must be interpreted or written to.
This allows us to centralize all pixel format conversion in one class,
`LibSoftGPU::PixelConverter`. For both the input and output image, it
takes a specification containing the image dimensions, the pixel type
and the selection (basically a clipping rect), and converts the pixels
from the input image to the output image.
Effectively this means we now support almost all OpenGL 1.5 formats,
and all custom logic has disappeared from:
- `glDrawPixels`
- `glReadPixels`
- `glTexImage2D`
- `glTexSubImage2D`
The new logic is still unoptimized, but on my machine I experienced no
noticeable slowdown. :^)

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.
|
|
Instead we just use a specific constructor. With this set of
constructors using curly braces for constructing is highly recommended.
As then it will not do too many implicit conversions which could lead to
unexpected loss of data or calling the much slower double constructor.
Also to ensure we don't feed (Un)SignedBigInteger infinities we throw
RangeError earlier for Durations.
|
|
For now this will assume that the double given is exactly representable
as an integer, so no NaN, infinity or rounding.
|
|
This means it can take any (un)signed word of size at most Word.
This means the constructor can be disambiguated if we were to add a
double constructor :^).
This requires a change in just one test.
|
|
This allows using different options for rounding, like IEEE
roundTiesToEven, which is the mode that JS requires.
Also fix that the last word read from the bigint for the mantissa could
be shifted incorrectly leading to incorrect results.
