This commit teaches BindingsGenerator to generate depfiles, which can be
used by CMake to ensure that bindings are properly regenerated when
imported IDL files change.
Two new options, `--depfile` and `--depfile-target` are added.
- `--depfile` sets the path for the dependency file.
- `--depfile-target` lets us set a target name different than the output
file in the depfile. This option is needed because generated files are
first written to a temporary file, but depfiles have to refer to the
final location.
These are analogous to GCC's `-MF` and `-MT` options respectively. The
depfile's syntax matches the ones generated by GCC.
Note: This changes the minimal required CMake version to 3.20 if the
Make generator is used, and to 3.21 for the Xcode generator. Ninja is
not affected.
This generally seems like a better name, especially if we somehow also
need a better name for "read the entire buffer, but not the entire file"
somewhere down the line.
For example, Document.getSelection returns Selection, which is in the
Selection namespace.
Namespaces.h has Linus' copyright since he changed the "is_one_of" list
to an Array.
`Core::Stream::File` shouldn't hold any utility methods that are
unrelated to constructing a `Core::Stream`, so let's just replace the
existing `Core::File::exists` with the nicer looking implementation.
Note that js_rope_string() has been folded into this, the old name was
misleading - it would not always create a rope string, only if both
sides are not empty strings. Use a three-argument create() overload
instead.
Gfx::Color is always 4 bytes (it's just a wrapper over u32) it's less
work just to pass the color directly.
This also updates IPCCompiler to prevent from generating
Gfx::Color const &, which makes replacement easier.
This will make it easier to support both string types at the same time
while we convert code, and tracking down remaining uses.
One big exception is Value::to_string() in LibJS, where the name is
dictated by the ToString AO.
We have a new, improved string type coming up in AK (OOM aware, no null
state), and while it's going to use UTF-8, the name UTF8String is a
mouthful - so let's free up the String name by renaming the existing
class.
Making the old one have an annoying name will hopefully also help with
quick adoption :^)
This was forgotten to be added in the LibWeb GC conversion.
This caused some brand checks to fail in skribbl.io's JavaScript and
thus caused unexpected exceptions.
Hand-picking the smallest index type that fits a particular generated
array started with commit 3ad159537e. This
was to reduce the size of the generated library.
Since then, the number of types using UniqueStorage has grown a ton,
creating a long list of types for which index types are manually picked.
When a new UCD/CLDR/TZDB is released, and the current index type no
longer fits the generated data, we fail to generate. Tracking down which
index caused the failure is a pretty annoying process.
Instead, we can just use size_t while in the generators themselves, then
automatically pick the size needed for the generated code.
When an IPC message returns a single value, we generate a class with a
constructor that is something like:
class MessageResponse {
MessageResponse(SingleReturnType value)
: m_value(move(value))
{
}
};
If that IPC message wants to return a value that SingleReturnType is
constructible from, you have to wrap that return call with braces:
return { value_that_could_construct_single_return_type };
That isn't really an issue except for when we want to mix TRY semantics
with the return type. If SingleReturnType is constructible from an Error
type (i.e. something similar to ErrorOr), the following doesn't work:
TRY(fallible_function());
Because MessageResponse would not be constructible from Error. Instead,
we must do some workaround with a custom TRY macro, as in 31bb792.
This patch generates a constructor that makes TRY usable as-is without
any custom macros. We perform a very similar trick in ThrowCompletionOr
inside LibJS. This constructor will allow you to create MessageResponse
from any type that SingleReturnType is constructible from.
Previously each emoji had its own symbol in the library which was then
referred to by another symbol. This caused thousands of avoidable data
relocations at load time.
This saves about 122kB RAM for each process which uses LibUnicode.
Previously the s_decomposition_mappings variable would refer to other
data in s_decomposition_mappings_data. This would cause thousands of
avoidable relocations at load time.
This saves about 128kB RAM for each process which uses LibUnicode.
We currently have two build-time parsers for the UCD's emoji-test.txt
file. To prepare for future changes, this removes the Bash parser and
moves its functionality to the newer C++ parser.
There were some notable changes to the CLDR JSON format and data in this
release.
The patterns for a date at a specific time, i.e. "{date} at {time}", now
appear under the "atTime" attribute of the "dateTimeFormats" object.
Locale specific changes that affected test-js:
All locales:
* In many patterns, the code points U+00A0 (NO-BREAK SPACE) and U+202F
(NARROW NO-BREAK SPACE) are now used in place of an ASCII space. For
example, before the "dayPeriod" fields AM and PM.
* Separators such as U+2013 (EN DASH) are now surrounded by U+2009 (THIN
SPACE) in place of an ASCII space character.
Locale "en":
* Narrow localizations of time formats are even more narrow. For
example, the abbreviation "wk." for "week" is now just "wk".
Locale "ar":
* The code point U+060C (ARABIC COMMA) is now used in place of an ASCII
comma.
* The code point U+200F (RIGHT-TO-LEFT MARK) now appears at the
beginning of many localizations.
* When the "latn" numbering system is used for currency formatting, the
currency symbol more consistently is placed at the end of the pattern.
Locale "he":
* The "many" plural rules category has been removed.
Locales "zh" and "es-419":
* Several display-name localizations were changed.
Due to the way we lazily construct prototypes and constructors for web
platform interfaces, it's possible for nested GC allocation to occur
while GC objects have been allocated but not fully constructed.
If the garbage collector ends up running in this state, it may attempt
to call JS::Cell::visit_edges() on an object whose vtable pointer hasn't
been set up yet.
This patch works around the issue by deferring GC while intrinsics are
being brought up. Furthermore, we also create a dummy global object for
the internal realm, and populate it with intrinsics. This works around
the same issue happening when allocating something (like the default UA
stylesheets) in the internal realm.
These solutions are pretty hacky and sad, so I've left FIXMEs about
finding a nicer way.
Get rid of the bespoke NavigatorObject class and use the modern IDL
strategies for creating platform objects to re-implement Navigator and
its associcated mixin interfaces. While we're here, implement it in a
way that brings WorkerNavigator up to spec :^)
This new code generator takes all the .idl files in LibWeb, looks for
each top level interface in there with an [Exposed=Foo] attribute, and
adds code to add the constructor and prototype for each of those exposed
interfaces to the realm of the relevant global object we're initialzing.
It will soon replace WindowObjectHelper as the way that web interfaces
are added to the Window object, and will be used in the future for
creating proper WorkerGlobalScope objects for dedicated and shared
workers.
Instead, create a tree of Parsers all pointing to a top-level Parser.
All module imports and interfaces are stored at the top level, instead
of in a static map. This allows creating multiple IDL::Parsers in the
same process without them stepping on each others toes.
An "inherit attribute" calls an ancestor's getter with the same name,
but defines its own setter. Since a parent class's public methods are
exposed to child classes, we don't have to do any special handling here
to call the parent's methods, it just works. :^)
The mappings are exposed via `Unicode::code_point_decomposition(u32)`
and `Unicode::code_point_decompositions()`, the latter being useful for
reverse searching a code point from its decomposition.
The normalization code does not make use of `Quick_Check` props (https://www.unicode.org/reports/tr44/#Decompositions_and_Normalization),
meaning no quick check optimizations.
