The JS::Intl enum was added when implementing the PluralRules
constructor. Now that LibUnicode has a plural rules implementation,
replace the JS::Intl enum with the analagous Unicode enum.
Plural rules in the CLDR are of the form:
"cs": {
"pluralRule-count-one": "i = 1 and v = 0 @integer 1",
"pluralRule-count-few": "i = 2..4 and v = 0 @integer 2~4",
"pluralRule-count-many": "v != 0 @decimal 0.0~1.5, 10.0, 100.0 ...",
"pluralRule-count-other": "@integer 0, 5~19, 100, 1000, 10000 ..."
}
The syntax is described here:
https://unicode.org/reports/tr35/tr35-numbers.html#Plural_rules_syntax
There are up to 2 sets of rules for each locale, a cardinal set and an
ordinal set. The approach here is to generate a C++ function for each
set of rules. Each condition in the rules (e.g. "i = 1 and v = 0") is
transpiled to a C++ if-statement within its function. Then lookup tables
are generated to match locales to their generated functions.
NOTE: -Wno-parentheses-equality is added to the LibUnicodeData compile
flags because the generated plural rules have lots of extra parentheses
(because e.g. we need to selectively negate and combine rules). The code
to generate only exactly the right number of parentheses is quite hairy,
so this just tells the compiler to ignore the extras.
The initialize_hba method now calls the reset method to reset the HBA
and initialize each AHCIPort. Also, after full HBA reset we need to turn
on the AHCI functionality of the HBA and global interrupts since they
are cleared to 0 according to the specification in the GHC register.
Instead of doing this in a parent class like the AHCIController, let's
do that directly in the AHCIPort class as that class is the only user of
these sort of physical pages. While it seems like we waste an entire 4KB
of physical RAM for each allocation, this could serve us later on if we
want to fetch other types of logs from the ATA device.
The way AHCIPortHandler held AHCIPorts and even provided them with
physical pages for the ATA identify buffer just felt wrong.
To fix this, AHCIPortHandler is not a ref-counted object anymore. This
solves the big part of the problem, because AHCIPorts can't hold a
reference to this object anymore, only the AHCIController can do that.
Then, most of the responsibilities are shifted to the AHCIController,
making the AHCIPortHandler a handler of port interrupts only.
The AHCI code is not very good at OOM conditions, so this is a first
step towards OOM correctness. We should not allocate things inside C++
constructors because we can't catch OOM failures, so most allocation
code inside constructors is exported to a different function.
Also, don't use a HashMap for holding RefPtr of AHCIPort objects in
AHCIPortHandler because this structure is not very OOM-friendly. Instead
use a fixed Array of 32 RefPtrs, as at most we can have 32 AHCI ports
per AHCI controller.
When compiling with Lagom, we give both LibWebSocket and the WebSocket
IPC service the Lagom:: prefix as an alias, but strip the Lib from all
library target names before applying the prefix. This creates a conflict
when external projects used the aliased name between the server and the
library. Give WebSocket a name that deconflicts it, but keep the binary
name the same, /bin/WebSocket.
Anonymous wrappers get their non-inherited properties from the initial
state of a new CSS::ComputedValues object. Before this patch, all the
values in their margin and padding LengthBox would be "auto".
Instead of recomputing the "remaining free space" per flex line,
remember it after calculating it during the "resolve flexible lengths"
step so we can reuse it later.
When we're performing max-content layout (a separate throwaway layout
pass that only exists to discover the intrinsic max-content size of
a specific box), we act as if the containing block has infinite width.
This allows an infinite length to propagate into the layout system,
which is fine, but at some point it needs to be turned into a finite
number or some loop conditions will not make sense and we can hang
indefinitely (e.g in the flexible lengths resolution algorithm.)
We fix this by making Length::resolved() turn non-finite values into
an "auto" length.
This includes:
* The minimum number of days in a week for that week to count as the
first week of a new year.
* The day to be shown as the first day of the week in a calendar.
* The start/end days of the weekend.
Like the existing hour cycle data, week data is presented per-region in
the CLDR, rather than per-locale. The method to add likely subtags to a
locale to perform region lookups is the same.
The list of regions in the CLDR for hour cycle, minimum days, first day,
and weekend days are quite different. So rather than changing the
existing HourCycleRegion enum to a generic Region enum, we generate
separate enums for each of the week data fields. This allows each lookup
into these fields to remain simple array-based index access, without any
"jumps" for regions that don't have CLDR data for a field.
Currently contains just each locale's character order, but is set up to
easily add other text layout fields from the CLDR if ECMA-402 eventually
requires them.
The zone1970.tab file in the TZDB contains regional time zone data, some
of which we already parse for the system time zone settings map.
This parses the region names from that file and generates a list of time
zones which are used in each of those regions.
This is a manual but clean revert of all commits from #12595.
Adding a partial implementation of the resizable ArrayBuffer proposal
without implementing all the updates to TypedArray infrastructure that
is also covered by the spec introduced a bunch of crashes, so we
decided to revert it for now until a full implementation is completed.
This patch removes deprecated GML properties and manual sizing
calculations in favor of the new UIDimensions, and registers more
widgets in the FontEditor namespace to simplify widget setup.
Add overrides for serenity_bin and serenity_lib to allow the actual
CMakeLists.txt from Userland to be used to build as many services as
possible without adding more clutter to Meta/Lagom/CMakeLists.txt
This matches the target names for the main serenity build, and will make
simplifying the Lagom build much easier going forward.
The LagomFoo name came from a time when we had both library builds in
the same CMake generated project and needed to deconflict the names.
In preparation for future refactoring of Lagom, let's use the variables
from GNUInstallDirs as much as possible for the helper macros and other
scripts used by the main build already.
