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.
This adds an API to use LibTimeZone to convert a time zone such as
"America/New_York" to a GMT offset string like "GMT-5" (short form) or
"GMT-05:00" (long form).
This is a rather naive implementation, but serves as a first pass at
determining the GMT offset for a time zone at a particular point in
time. This implementation ignores DST (because we are not parsing any
RULE entries yet), and ignores any offset patterns of the form "Mon>4"
or "lastSun".
For example, generate "Etc/GMT+12" as "Etc_GMT_Ahead_12" (instead of as
"Etc_GMT_P12"). A little clearer what the name means without having to
know off-hand what "P" was representing.
The generate_mapping helper generates a series of structs like:
Array<SomeType, 1> s_mapping_key_0 {};
Array<SomeType, 2> s_mapping_key_1 {};
Array<SomeType, 3> s_mapping_key_2 {};
Array<Span<SomeType const>> s_mapping { {
s_mapping_key_0.span(),
s_mapping_key_1.span(),
s_mapping_key_2.span(),
} };
Where the names of the struct were generated by the format_mapping_name
lambda inside the helper. Rather than this lambda making assumptions on
how each generator wants to name its structs, add a parameter for the
caller to provide a naming formatter.
This is because the TimeZoneData generator will want pretty specific
identifier formatting rules.
The special URL links (help://man) and the application opening links now
work on the man page website. While the page links are translated
correctly, the application launch can't be implemented. For this reason,
an explanatory error page is shown instead.
When compiled using clang, an ambiguity error is detected between
`class AK::Time` aliased to `::Time` and the `struct ::Time` provided
in `GenerateTimeZoneData.cpp`. Solve this by moving most of the code in
an anonymous namespace.
In the last few commits, a second patch was added to the LLVM toolchain,
and it no longer uses our binutils patch. This commit changes the CI
cache keys accordingly, in order to prevent unnecessary rebuilds of both
toolchains when only one is changed.
The Clang toolchain's cache now only takes into account patches that
begin with `llvm`, and the GNU toolchain excludes those from the hash
calculation. We now also hash the two CMake cache files that we use for
building LLVM and its runtime libraries.
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.
