Instead of making it a void function, checking for an exception, and
then receiving the relevant result via VM::last_value(), we can
consolidate all of this by using completions.
This allows us to remove more uses of VM::exception(), and all uses of
VM::last_value().
LibUnicode no longer needs to generate a list of time zone names that it
parsed from metaZones.json. We can defer to the TZDB for a golden list
of time zones.
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.
The toolchain is built in a previous stage, but once the Serenity stage
has begun, we have to re-pull the toolchain from the Azure cache. There
is a timing window where a cache-busting change can be commited between
these steps; to alleviate the affect this has, pull the toolchain ccache
so that the build only takes a few minutes instead of a couple hours.
The generator parses metaZones.json to form a mapping of meta zones to
time zones (AKA "golden zone" in TR-35). This parser errantly assumed
this was a 1-to-1 mapping.
In Unicode::get_time_zone_name(), we don't need to require that the time
zone is UTC for long- and short-style name lookups. This is required for
other styles, because they will depend on TZDB data - so move the VERIFY
to that scope.
When searching for the locale-specific flexible day period for a given
hour, we were neglecting to handle cases where the period crosses 00:00.
For example, the en locale defines a day period range of [21:00, 06:00).
When given the hour of 05:00, we were checking if (21 <= 5 && 5 < 6),
thus not recognizing that the hour falls in that period.
This is a temporary mechanism while LibUnicode is in an in-between state
where some symbols are weakly linked and others are dynamically loaded.
The latter require an asm() label to be loaded.
Currently, we load the generated Unicode symbols with dlopen at runtime.
This is unnecessary as of 565a880ce5.
Applications that want Unicode data now link directly against the shared
library holding that data. So the same functionality can be achieved
with weak symbols.
This requires an implementation of the "text preparation algorithm" as
specified here:
html.spec.whatwg.org/multipage/canvas.html#text-preparation-algorithm
However, we're missing a lot of things such as the
CanvasTextDrawingStyles interface, so most of the algorithm was not
implemented. Additionally, we also are not able to use a LineBox like
the algorithm suggests, because our layouting infra is not up to the
task yet. The prepare_text function does nothing other than figuring out
the width of the given text and return glyphs with offsets at the
moment.
ECMA-402 now supports short-offset, long-offset, short-generic, and
long-generic time zone name formatting. For example, in the en-US locale
the America/Eastern time zone would be formatted as:
short-offset: GMT-5
long-offset: GMT-05:00
short-generic: ET
long-generic: Eastern Time
We currently only support the UTC time zone, however. Therefore, this
very minimal implementation does not consider GMT offset or generic
display names. Instead, the CLDR defines specific strings for UTC.
Add an option to enable NVMe storage device as the boot
drive.
To enable NVMe support, run the following:
$ SERENITY_NVME_ENABLE=1 Meta/serenity.sh run i686 root=/dev/nvme0n1
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 :^)
egcc is the alias for the GCC compiler (since OpenBSD uses Clang by
default). Toolchain/BuildIt.sh has the necessary adjustments, but the
compiler check occurs before BuildIt.sh is called.
OpenBSD gzip does not have the -k flag to keep the original after
extraction. Work around this by copying the original gzip to the dest
and then extracting. A bit of a hack, but only needs to be done for the
first-time or rebuilds
OpenBSD provides crypt in libc, not libcrypt. Adjust if/else to check
for either and proceed accordingly
Remove outdated OpenBSD checks when building the toolchain
I've seen how @awesomekling changes the script to disable KVM, so
that's a useful thing to have.
An example how to use it:
SERENITY_KVM_SUPPORT='0' ./Meta/serenity.sh run x86_64
My first commit btw :^)
This introduces a new library, LibSoftGPU, that incorporates all
rendering related features that formerly resided within LibGL itself.
Going forward we will make both libraries completely independent from
each other allowing LibGL to load different, possibly accelerated,
rendering backends.
ISO C requires in section 7.2:
The assert macro is redefined according to the current state of NDEBUG
each time that <assert.h> is included.
Also add tests for `assert` multiple inclusion accordingly.
PVS Studio static analysis noticed we didn't initialize these in a
bunch of cases. This change fixes that so we will always initialize
these using universal initialization.
