This was meant to be a temporary unit testuntil we could run test-js
in bytecode mode. This has been possible for a long time now, so let's
remove the unnecessary extra program.
GCC's build fails in `libisl`'s configure step if `CC` is set to
Homebrew Clang with the message "Link Time Optimisation is not
supported". This is likely due to the fact that it tries to use ranlib
from Xcode, which is not compatible with the newer LLVM version's
bitcode format.
The toolchain build runs after `pick_host_compiler` is called, which
selects Homebrew Clang if the installed Xcode version is too old. We
need to unset `CC` and `CXX` for the toolchain build to sidestep the
issue.
This reduced the runtime of `lint-ports` from 72s down to 0.5s on
my computer (a reduction of ~99.2%)! While it may not be as
accurate as running `package.sh showproperty` it makes using
`precommit` while editing ports much nicer!
Don't try to implement this AO in bytecode. Instead, the bytecode
Interpreter class now has a run() API with the same inputs as the AST
interpreter. It sets up the necessary environments etc, including
invoking the GlobalDeclarationInstantiation AO.
This creates (and installs upon WebContent startup) a platform plugin to
play audio data.
On Serenity, we use AudioServer to play audio over IPC. Unfortunately,
AudioServer is currently coupled with Serenity's audio devices, and thus
cannot be used in Ladybird on Lagom. Instead, we use a Qt audio device
to play the audio, which requires the Qt multimedia package.
While we use Qt to play the audio, note that we can still use LibAudio
to decode the audio data and retrieve samples - we simply send Qt the
raw PCM signals.
This does a few things:
- The decoder uses a 32- or 64-bit integer as a reservoir of the data
being decoded, rather than one single byte as it was previously.
- `read_bool()` only refills the reservoir (value) when the size drops
below one byte. Previously, it would read out a bit-sized range from
the data to completely refill the 8-bit value, doing much more work
than necessary for each individual read.
- VP9-specific code for reading the marker bit was moved to its own
function in Context.h.
- A debug flag `VPX_DEBUG` was added to optionally enable checking of
the final bits in a VPX ranged arithmetic decode and ensure that it
contains all zeroes. These zeroes are a bitstream requirement for
VP9, and are also present for all our lossy WebP test inputs
currently. This can be useful to test whether all the data present in
the range has been consumed.
A lot of the size of this diff comes from the removal of error handling
from all the range decoder reads in LibVideo/VP9 and LibGfx/WebP (VP8),
since it is now checked only at the end of the range.
In a benchmark decoding `Tests/LibGfx/test-inputs/4.webp`, decode times
are improved by about 22.8%, reducing average runtime from 35.5ms±1.1ms
down to 27.4±1.1ms.
This should cause no behavioral changes.
On macOS, CMake incorrectly tries to add and/or remove rpaths from files
that it has already processed when it performs installation. Setting the
rpaths during the build process ensures that they are only set once, and
as a bonus, makes installation slightly more performant.
Fixes#10055.
This broke in c2e24a2fa1 where the boot
drive was removed from `SERENITY_MACHINE`. We now add the boot drive to
the common Qemu arguments, so it gets included in the aarch64 run
configuration as well.
The PNP IDs data file was recently updated with an accidental duplicate
entry (HONOR Device Co., Ltd.). Rather than breaking everyone's build,
let's just ignore duplicates.
Generated iterator prototypes already have the IteratorPrototype as
their prototype, but we were incorrectly hijacking them and rerouting
to ObjectPrototype.
Regressed in cfe663435e.
If a local include does not point to a file in the repository, it should
be a system include instead. This is now checked on every commit.
While this does introduce significant overhead in terms of percentage,
I think that an additional 10ms on huge commits (or less on smaller
commits) are acceptable:

Previously this was compiled to require an object despite the IDL file
specifying 'optional'.
This commit makes IDLGenerator respect this modifier, and fixes the only
affected instance.
This partially implements CSS-Animations-1 (though there are references
to CSS-Animations-2).
Current limitations:
- Multi-selector keyframes are not supported.
- Most animation properties are ignored.
- Timing functions are not applied.
- Non-absolute values are not interpolated unless the target is also of
the same non-absolute type (e.g. 10% -> 25%, but not 10% -> 20px).
- The JavaScript interface is left as an exercise for the next poor soul
looking at this code.
With those said, this commit implements:
- Interpolation for most common types
- Proper keyframe resolution (including the synthetic from-keyframe
containing the initial state)
- Properly driven animations, and proper style invalidation

This will make it a lot easier to understand what went wrong, especially
when the failure occurs on CI but not at home.
And of course, use LibDiff to generate the diff! :^)
It does not make sense to test known-working code that is deprecated and
in the process of being removed. Also, this test becomes too cumbersome
to write without using read_all or line iteration in some form, and
migrating the test is just silly.
That's what this class really is; in fact that's what the first line of
the comment says it is.
This commit does not rename the main files, since those will contain
other time-related classes in a little bit.
There have been multiple reports of Xcode 14.0 (based on upstream LLVM
14) segfaulting when compiling `LibCore/Process.cpp`. Let's require
Xcode 14.3, which is a known good version based on LLVM 15.
Note that Xcode 14.3 requires macOS Ventura, so users of Monterey or
older are expected to get Homebrew Clang instead.
Homebrew Clang 13 also suffers from the same crash. Although I have not
tested on Linux, the backtrace points to the middle-end, so x86_64 is
also likely to be affected. LLVM 14 was released 14 months ago, so it's
not an unreasonable requirement.
It's not safe to allocate from the GC heap while in the constructor of a
GC heap cell. (Because if this ends up triggering a collection, we may
end up trying to call through an uninitialized vtable).
This was already done safely in the initialize() virtual in much of
LibJS and LibWeb. This patch moves the logic for prototypes, mixins,
and CSSStyleDeclaration as well.
Fixes a long-standing GC crash that was pretty easy to reproduce by
refreshing https://vercel.com/
This completion only works if you have lagom already built in some
capacity, since it scans the build directory tree for binaries, removing
known false positives. However, that is both more accurate than asking
ninja for the targets and filtering those, and it also makes it
independent of the build system used.
This is very convenient for anyone like me who regularly runs the Clang
toolchain. The toolchain is not completed for Lagom and the
toolchain-independent help command.
This in turn enables `./Meta/serenity.sh test aarch64` and the CI
scripts to work with the AArch64 port.
As the RPi doesn't have a debugcon-like device, we create two serial
devices. The system console, UART0 is redirected to `debug.log`, while
UART1 is made available to the userspace and is used as the stdout for
the test runner script.
We are not yet able to run the full test suite, as the kernel panics due
to some unimplemented features.
Note that Qemu `master` or our patched Qemu build is required for
`SystemServer` to recognize the `system_mode=self-test` parameter.
Newer versions of QEMU prevent the user from running a GL-rendered
display while a SPICE display is active due to incompatibilities.
Since there is no way to disable QEMUs (apparently implicit) SPICE
display, make sure that we only enable SPICE support if the user
requested running with SPICE specifically. In this case, QEMU picks the
default SPICE client instead of rendering a display using whatever our
default on that platform would be.
We already install C++ source files to allow debugging applications
in HackStudio.
Installing GML files can make editing application widgets a bit faster
and easier, as you no longer need to copy files to the system. :^)
This little program allows us to take the NetworkSettings app away
from being an elevated GUI app.
It receives a JsonObject on STDIN and writes it to the global
Network configuration file.
If the write was successfull it will apply the changes.
We now load SVG icons (via the Qt resource system) and render them into
a QIcon (with normal and disabled variants) using system colors.
We also re-render them if the system color theme changes.
This instantly makes Ladybird look less foreign on my Linux box.
I drew the icons myself, and they could definitely be more optimized,
but this was my first time using Inkscape. :^)
GCC 13 was released on 2023-04-26. This commit fixes Lagom build errors
when using an updated host toolchain:
- Adds a workaround for a bug in constraint handling, which made LibJS
fail to compile: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=109683
- Silences the new `-Wdangling-reference` diagnostic globally. It
produces multiple false positives with no clear way to silence them
without `#pragmas`.
- Silences `-Wself-move` in `RefPtr` tests as GCC 13 adds this
previously Clang-exclusive warning.
This ensures that all visit_edges implementations include a call to
Base::visit_edges. In particular, this gives three nice benefits:
- The call can't be forgotten (the main benefit, of course).
- All of the calls look the same. In other words, always use "Base"
instead of the actual concrete class.
- Ensure the object has a call to JS_CELL or JS_OBJECT in the
definition. Otherwise, Base will not be defined and the call will
not compile.
Some hardware/software configurations crash KVM as soon as we try to
start Serenity. The exact cause is currently unknown, so just fully
revert it for now.
This reverts commit 897c4e5145.
The new baked image is a Prekernel and a Kernel baked together now, so
essentially we no longer need to pass the Prekernel as -kernel and the
actual kernel image as -initrd to QEMU, leaving the option to pass an
actual initrd or initramfs module later on with multiboot.
That pattern seems to show up a lot in code written by people that
aren't intimately familiar with the lifetime model of Error and Strings.
This commit makes the compiler detect it and present a more helpful
diagnostic than "garbage string at runtime".
This class can be used to run a task in another thread, and allows the
caller to wait for the task to complete to retrieve any error that may
have occurred.
Currently, it doesn't support functions returning a value on success,
but with some template magic that should be possible. :^)
For the most part no behavior change, except that we now pass
-Wno-implicit-const-int-float-conversion and -Wno-literal-suffix
only to clang and gcc each in both lagom and serenity builds,
while we previously passed them to both in lagom builds (and
passed them to one each in serenity builds). The former is
a clang flag, the latter a gcc flag, but since we also use
-Wno-unknown-warning-option it doesn't really matter.
In CLDR 42 and earlier, we were able to assume all cldr-localename files
existed for every locale. They now do not exist for locales that don't
provide any localized data. Namely, this is the "und" locale (which is
an alias for the root locale, i.e. the locale we fall back to when a
user provides an unknown locale).
Further, we were previously able to assume that each currencies.json in
cldr-numbers contained all currencies. This file now excludes currencies
whose localized names are the same as the currency key. Therefore, we
now preprocess currencies.json to discover all currencies ahead of time,
much like we already do for languages.json.
Some of these are allocated upon initialization of the intrinsics, and
some lazily, but in neither case the getters actually return a nullptr.
This saves us a whole bunch of pointer dereferences (as NonnullGCPtr has
an `operator T&()`), and also has the interesting side effect of forcing
us to explicitly use the FunctionObject& overload of call(), as passing
a NonnullGCPtr is ambigous - it could implicitly be turned into a Value
_or_ a FunctionObject& (so we have to dereference manually).
Previously, the condition was reversed, so we would stop immediately on
a file that has at least one working chunk, and we would infinitely loop
on a file with no chunks.
Target GDB is only used for debugging the kernel, which is not relevant
to most people. Starting with 924758c6f8, GDB would always be built
as part of the toolchain if the user didn't have it installed. This is
unnecessary.
This commit adds a separate script for building GDB, which the user
needs to explicitly invoke. A message is added to Meta/debug-kernel.sh
which alerts the user to this fact.
When we had 32 bit support in the OS kernel and userland, the very bare
minimum CPU we supported was Pentium 3, but now the CPU is just required
to support x86-64 long mode to be supported, so the exact model is not
very important.
I chose the QEMU64 virtual CPU model, because the whole concept of the
QEMU ISA-PC machine is that it checks how the kernel handles arbitrarily
old hardware setup.
Loads of changes that are tightly connected... :/
* Change lambdas to static functions
* Add spec docs to those functions
* Keep the current scope around as a parameter
* Add wrapping classes for some Certificate members
* Parse ec and ecdsa data from certificates
Previously, we would unconditionally build GDB from source for the
AArch64 toolchain. This commit makes it possible to use the system's
`gdb` binary if it supports the architecture, or `aarch64-elf-gdb` if
such a package is installed.
An `aarch64-elf-gdb` package will be available through Homebrew once
this PR is merged: https://github.com/Homebrew/homebrew-core/pull/127323
This solves the longhands must be initialized before shorthands
problem by just initializing the value when it is first requested.
This will be needed for background-position-x/y which is a longhand
of a longhand, which otherwise breaks the longhands before shorthands
rule.
This makes it easy to compare the performance of Serenity's
deflate implementation to the host system implementation.
On my M1 Max MBP:
% time gunzip -c \
/Users/thakis/Downloads/trace_bug.json.gz > /dev/null
takes between 0.064s and 0.082s.
% time Build/lagom/gunzip -c \
/Users/thakis/Downloads/trace_bug.json.gz > /dev/null
on the other hand takes 4 seconds.
(That .gz file is a 5.8M file -- the largest .gz file that happend to be
in my Downloads folder.)
This is an implementation that tries to follow the spec as closely as
possible, and works with Qemu's Intel HDA and some bare metal HDA
controllers out there. Compiling with `INTEL_HDA_DEBUG=on` will provide
a lot of detailed information that could help us getting this to work
on more bare metal controllers as well :^)
Output format is limited to `i16` samples for now.
`SERENITYOS` is also set when compiling Lagom on SerenityOS, so we can't
just check it and expect `CMAKE_STAGING_PREFIX` to be set.
Instead, check `CMAKE_STAGING_PREFIX` directly and use that as an
indicator for whether we can install a file there.
It appears that QEMU on macOS doesn't have the VirtIO GPU variants that
support VGA functionality. Those variants are not especially important
to us, because we don't use any kind of VGA functionality in our kernel
anyway.
Therefore, for macOS, we could decide to use virtio-gpu-gl-pci and
virtio-gpu-pci devices instead.
Required by code that brand checks native constructors.
For example, Wistia brand checks XMLHttpRequest by doing:
```
XMLHttpRequest.prototype.constructor.toString()
```
It then checks if it matches either one of:
```
function XMLHttpRequest() { [native code] }
```
```
[object XMLHttpRequestConstructor]
```
If neither matches, it disables HLS playback and prints:
"The XMLHttpRequest constructor has been tampered with. Because this
affects CORS/Range XHR requests, HLS playback has been disabled.
To enable HLS playback and other important features, please remove code
that changes the definition of window.XMLHttpRequest."
We hit this path due to not giving generated constructors a name, as
we would provide `function () { [native code] }`.
This patch parses enough of GPOS tables to be able to support the
kerning information embedded in Inter.
Since that specific font only applies positioning offsets to the first
glyph in each pair, I was able to get away with not changing our API.
Once we start adding support for more sophisticated positioning, we'll
need to be able to communicate more than a simple "kerning offset" to
the clients of this code.
Currently, the WebAssemblyObject implements a visitor to keep its static
objects alive. This custom attribute will be used to hook the generated
namespace object's visitor to one that we define in non-generated code.
Interfaces with a LegacyNamespace extended attribute should have their
constructors defined on the namespace identified by the LegacyNamespace
attribute value.
This is used by WebAssembly IDL files. For now, we mostly use this for
error messages and cache keys (to ensure compatibility with existing
code as WebAssembly is ported to IDL).
For example, consider the attribute:
interface Element {
[PutForwards=value] readonly attribute DOMTokenList classList;
}
When `classList` is set, we should instead set the attribute `value` on
the `classList` attribute of the Element interface.
Don't try to reserve capacity for a variadic arguments list unless we
actually have enough arguments to fill it with anything. Otherwise we
may overflow to an extremely large size if, e.g., the argument count
is 0 and the start of the variadic arguments is index 1.
We can always read the basic format information (sample rate, bit depth,
etc.), but we will also print artist, album, and title if available in
the metadata.
Similar to POSIX read, the basic read and write functions of AK::Stream
do not have a lower limit of how much data they read or write (apart
from "none at all").
Rename the functions to "read some [data]" and "write some [data]" (with
"data" being omitted, since everything here is reading and writing data)
to make them sufficiently distinct from the functions that ensure to
use the entire buffer (which should be the go-to function for most
usages).
No functional changes, just a lot of new FIXMEs.
Before, some loader plugins implemented their own buffering (FLAC&MP3),
some didn't require any (WAV), and some didn't buffer at all (QOA). This
meant that in practice, while you could load arbitrary amounts of
samples from some loader plugins, you couldn't do that with some others.
Also, it was ill-defined how many samples you would actually get back
from a get_more_samples call.
This commit fixes that by introducing a layer of abstraction between the
loader and its plugins (because that's the whole point of having the
extra class!). The plugins now only implement a load_chunks() function,
which is much simpler to implement and allows plugins to play fast and
loose with what they actually return. Basically, they can return many
chunks of samples, where one chunk is simply a convenient block of
samples to load. In fact, some loaders such as FLAC and QOA have
separate internal functions for loading exactly one chunk. The loaders
*should* load as many chunks as necessary for the sample count to be
reached or surpassed (the latter simplifies loading loops in the
implementations, since you don't need to know how large your next chunk
is going to be; a problem for e.g. FLAC). If a plugin has no problems
returning data of arbitrary size (currently WAV), it can return a single
chunk that exactly (or roughly) matches the requested sample count. If a
plugin is at the stream end, it can also return less samples than was
requested! The loader can handle all of these cases and may call into
load_chunk multiple times. If the plugin returns an empty chunk list (or
only empty chunks; again, they can play fast and loose), the loader
takes that as a stream end signal. Otherwise, the loader will always
return exactly as many samples as the user requested. Buffering is
handled by the loader, allowing any underlying plugin to deal with any
weird sample count requirement the user throws at it (looking at you,
SoundPlayer!).
This (not accidentally!) makes QOA work in SoundPlayer.
headless-browser currently uses its own PageClient to load web pages
in-process. Due to this, it also needs to set up a whole bunch of other
objects needed to run LibWeb, e.g. image decoders, request servers, etc.
This changes headless-browser to instead implement a WebView to launch
WebContent out-of-process. This implementation is almost entirely empty,
but can be filled in as-needed. For example, we may want to print
JavaScript console messages.
At the moment, all it can do is read all image formats that LibGfx can
read and save to any image format that LibGfx can write (currently bmp,
png, qoi).
Currently, it drops all image metadata (including color profiles).
Over time, this could learn tricks like keeping color profiles,
converting an image to a different color profile, cropping out a part of
an image, and so on.
"image" was an alias for "qemu-image".
I want to add an `image` userland utility, which clashes with that
shortname.
So remove the existing "image" target. It was just an alias for
"qemu-image".
If you use serenity.sh to build, nothing changes. This only affects you
if you run ninja manually -- you now have to say `ninja qemu-image` to
build the disk image.
Commit: 2c84466ad8 ("Kernel/Storage: Introduce new boot device
addressing modes") changed the way we pass the boot device parameter.
That commit missed updating boot parameter in the run.sh script for NVMe
boot devices.
We should be able to run this locally, as long as ENABLE_LAGOM_LADYBIRD
is true, or if building ladybird from the ladybird source directory.
This removes a special case from the Lagom CI yml file.
Add some prose to the introduction of Lagom about how we use it. Also,
move the section on including Lagom in other projects above the fuzzer
documentation.
Remove the explicit cmake commands from the Fuzzer documentation, as the
script should be the source of truth.
When an IDL file has #imports and the IDL interface exposes an iterator,
the bindings generator would generate #include statements missing the
class name of the iterator in the form 'LibWeb/{namespace}/Iterator'.
This change only generates the iterator #include statement for the top
interface that is the iterator.
These are treated differently as the interface members are placed on the
object itself, not its prototype.
As the object itself still needs to be hand-written code, and we can no
longer fully hide the gnarly generated code in the prototype object,
these now generate a 'mixin' class that is added to the actual object
through inheritance.
https://webidl.spec.whatwg.org/#Global
The Window object is massive, so let's do the conversion to IDL step
by step. First up: getting rid of the manual constructor and prototype
definitions, which can be generated from an empty `interface Window`.
This relied on pulling the current realm from the main thread VM, which
requires an execution context to be on the VM's stack. This heavily
relied on the dummy execution context that is always on the stack, for
example, when parsing the UA style sheets where no JavaScript is
running.
This class had slightly confusing semantics and the added weirdness
doesn't seem worth it just so we can say "." instead of "->" when
iterating over a vector of NNRPs.
This patch replaces NonnullRefPtrVector<T> with Vector<NNRP<T>>.
This is implemented as a Clang frontend tool, and currently does two
things:
- Ensure for all fields wrapped in {Nonnull,}GCPtr<T>, T inherits from
JS::Cell
- Ensure for all fields not wrapped in {Nonnull,}GCPtr, that the type
does not inherit from JS::Cell (otherwise it should be wrapped in a
Ptr class).
In the future, this tool could be extended further. For example, we may
consider validating all implementations of Cell::visit_impl.
This also removes DirIterator::error_string(), since the same strerror()
string will be included when you print the Error itself. Except in `ls`
which is still using fprintf() for now.
This sorts the array of generated emoji data by code point (first by
code point length, then by code point value). This lets us use a binary
search to find emoji data, rather than the current linear search.
In a profile of scrolling around /home/anon/Documents/emoji.txt, this
reduces the runtime of Gfx::Emoji::emoji_for_code_points from 69.03% to
28.42%. Within that, Unicode::find_emoji_for_code_points reduces from
28.42% to just 1.95%.
These symlinks' only purpose was to be copied into the rootfs along with
the rest of Base. Instead of storing symlinks to files that either
don't exist in the Base directory, or point to an absolute path outside
of the serenity folder, move these symlinks into the
build-root-filesystem.sh script.
Similar to the FontDatabase, this will be needed for Ladybird to find
emoji images. We now generate just the file name of emoji image in
LibUnicode, and look for that file in the specified path (defaulting to
/res/emoji) at runtime.
`consume_until(foo)` stops before foo, and so does
`ignore_until(Predicate)`, so let's make the other `ignore_until()`
overloads consistent with that so they're less confusing.
This commit moves the implementation of getopt into AK, and converts its
API to understand and use StringView instead of char*.
Everything else is caught in the crossfire of making
Option::accept_value() take a StringView instead of a char const*.
With this, we must now pass a Span<StringView> to ArgsParser::parse(),
applications using LibMain are unaffected, but anything not using that
or taking its own argc/argv has to construct a Vector<StringView> for
this method.
