This file will be the basis for abstracting away the out-of-thread or
later out-of-process decoding from applications displaying videos. For
now, the demuxer is hardcoded to be MatroskaParser, since that is all
we support so far. The demuxer should later be selected based on the
file header.
The playback and decoding are currently all done on one thread using
timers. The design of the code is such that adding threading should
be trivial, at least based on an earlier version of the code. For now,
though, it's better that this runs in one thread, as the multithreaded
approach causes the Video Player to lock up permanently after a few
frames are decoded.

The class is virtual and has one subclass, SubsampledYUVFrame, which
is used by the VP9 decoder to return a single frame. The
output_to_bitmap(Bitmap&) function can be used to set pixels on an
existing bitmap of the correct size to the RGB values that
should be displayed. The to_bitmap() function will allocate a new bitmap
and fill it using output_to_bitmap.
This new class also implements bilinear scaling of the subsampled U and
V planes so that subsampled videos' colors will appear smoother.

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.

So far we've gotten away with using GCC 11 for Lagom and to compile the
toolchain, but via #15795 we discovered a compiler bug that has been
fixed in the latest version but would error the build with CI's GCC 11.
Time for an upgrade :^)
We already use ubuntu-22.04 images in most places, so this is pretty
straightforward. The only exception is Idan's self-hosted runner, which
uses Ubuntu Focal. LibJS should build fine with GCC 11, still.

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.

We don't yet have anything else than SDL, and certainly not GTK.

This ensures that the toolchain building scripts will use the host
toolchain that has been found manually, and that they won't fall back to
`cc` (which in the worst case may not even be installed).

Homebrew does not add upstream LLVM's install location to $PATH so as
not to conflict with XCode tools, so we need to run `brew --prefix llvm`
to figure out its install path.

This is a manual revert of commit: 7831e62
Let's revert this until we got nested union support in our IDL
generator/parser.
|
|
This case requires some special handling, since there's no direct C++
inheritance relationship between HTML::WindowProxy and DOM::EventTarget.
|
|
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.

This allows a developer who only wants to look at Lagom to have their
IDE find source files and headers properly.
|

We have logic for serenity_generated_sources which works well for source
files that are specified in GENERATED_SOURCES prior to calling
serenity_lib or serenity_bin. However, code generated with
invoke_generator, and the LibWeb generators do not always follow the
pattern of the IDL and GML files.
For the LibWeb generators, we can just add_dependencies to LibWeb at the
time we declare the generate_Foo custom target. However for LibLocale,
LibTimeZone, and LibUnicode, we don't have the name of the target
available, so export the name in a variable to set into
GENERATED_SOURCES.
To make this work for Lagom, we need to make sure that lagom_lib and
serenity_bin in Lagom/CMakeLists.txt call serenity_generated_sources on
the target.
This enables the Xcode generator on macOS hosts, at least for Lagom.
|
|
This matches serenity_lib, and consolidates the logic to strip Lib from
the front of the library name for the Lagom export name into one place
at the top of lagom_lib.

Back when adding support for `pls` as a `sudo` replacement,
`build-image-qemu` dynamically set the `SUDO` variable depending on what
system it was running on and used the contents of that variable to call
the correct elevation utility.
During recent changes to the elevation error message, that usage of the
variable was replicated across all of our scripts, but without also
replicating the logic to set that variable in the first place.
Add back the variable setting logic to all the other scripts to keep
them from running into unset variables.

This became unused after 1ae0cfd.

We needed this back when we included Lagom into the main serenity build,
but it has been unecessary since the superbuild.
|
|
Also do this for Shell.
This greatly simplifies the CMakeLists in Lagom, replacing many glob
patterns with a big list of libraries. There are still a few special
libraries that need some help to conform to the pattern, like LibELF and
LibWebView.
It also lets us remove essentially all of the Serenity or Lagom binary
directory detection logic from code generators, as now both projects
directories enter the generator logic from the same place.
|
|
This lets us eliminate the "meta prefix" for the LibTimeZone generators.
|
|
By deferring to the CMakeLists in each of these libraries' directories,
we can get rid of a lot of curious GLOB patterns and list removals in
the Lagom CMakeLists.
|
|
This patch adds support for posting a DOM::Document using XHR::send().
|
|
Previously we'd add [component_name-NOTFOUND] sections to the
components.ini file for targets which weren't part of a component.
|
|
This commit adds read-only support for the FAT32 filesystem. It also
includes support for long file names.
|
|
Before, and that was the cause of many confusion in #build-problems
on Discord, the Meta/build-image-*.sh scripts would error out with
the message "this script needs to run as root" while the actual error
was unrelated.
|
|
All actual plugins follow the same logic to initialize their stream,
this commit factorizes all of this to their base class: `LoaderPlugin`.

There are no more users of this legacy version API. :yakgone:

WebDriver aims to implement the WebDriver specification found at
https://w3c.github.io/webdriver/webdriver-spec.html . It's an HTTP
server that can create Browser sessions and control them.

This file implements the POSIX APIs from <regex.h>, and is not suitable
for inclusion in a Lagom build. If we do include it, it will override
the host's regex functions and wreak havoc if it's resolved before the
host's implementation.

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.
