This warning warns about variable-length arrays being a non-standard
extension to the C++ language. We still have a few instances of VLAs, so
let's disable the warning for now.
This does not interfere with `-Wvla`, which we use to completely forbid
this (potentially dangerous) feature in the Kernel and LibCrypto.
The AppKit chrome is now the default, but the Qt chrome may still be
enabled for testing. Let's ensure it can compile in CI, as it has
already broken since the default change.
Previously, some fuzzers were generating an excessive amount of debug
logging. This change explicitly disables debug logging for all fuzzers.
This allows higher test throughput and makes the logs easier to read
when fuzzing locally.
The previous implementation was calling `backtrace()` for every
function call, which is quite slow.
Instead, this implementation provides VM::stack_trace() which unwinds
the native stack, maps it through NativeExecutable::get_source_range
and combines it with source ranges from interpreted call frames.
Previously these handlers duplicated code and used formats that
were different from the one Error.prototype.stack uses.
Now they use the same Error::stack_string function, which accepts
a new parameter for compacting stack traces with repeating frames.
This change introduces a new 2D graphics library that uses OpenGL to
perform painting operations. For now, it has extremely limited
functionality and supports only rectangle painting, but we have to
start somewhere.
Since this library is intended to be used by LibWeb, where the
WebContent process does not have an associated window, painting occurs
in an offscreen buffer created using EGL.
For now it is only possible to compile this library on linux.
Offscreen context creation on SerenityOS and MacOS will have to be
implemented separately in the future.

The current helpers assume that a valid URL is a full URL (i.e. contains
the "://" separator between the scheme and domain). This isn't true, as
"file:" alone is parsed as a valid URL.
We must also avoid simply searching for the parsed public suffix in the
original URL string. For example, "com" is a public suffix. If we search
for that in the URL "com.com", we will think the public suffix starts at
index 0.
This library offers tools to communicate with an ImageDecoder server
through IPC. There is currently no such executable for Lagom but that
shouldn't take long :^)
This was left behind when removing the AST interpreter, and the CI not
being around made it bitrot.

`-serial mon:stdio` passes through all kinds of key combinations,
`-serial stdio` doesn't. This probably isn't something that we want
while running tests or CI, so switch to the non-passing variant.
aarch64 actually failed to run due to this, since it already had
`-serial stdio` in its arguments, causing a conflict. This is why that
entry is now gone entirely.
`-nographic` additionally reconfigures the Terminal, which clears the
previous scrollback and (ocasionally) breaks line wrapping. This is
probably not something that we want, so only ask for the redirection
behavior.
Previously, attempting to update an ext2 inode with a UID or GID
larger than 65535 would overflow. We now write the high bits of UIDs
and GIDs to the same place that Linux does within the `osd2` struct.
* Elide parser offsets to better group parser errors
* Use `backslashreplace` for decoding crash stacks so that we don't
crash when printing crash stacks if the error output isn't valid
utf-8
* Swap last two lines of output, reads a bit better
The rendering happens only in-memory, so this is only useful for
looking at the crash rate and the reports of missing features.
To actually see the output of a file, use
pdf --render out.png --page N path/to/input.pdf
instead.
I would've expected that there's some way to have this work
automatically in an NSDocument-based application, but I haven't
found it yet. So manually implement the delegate for now.
After d2c7e1ea7d, there is now only one
user of LibPublicSuffix - the URL sanitation utility within LibWebView.
Rather than having an entire library for the small Public Suffix data
accessor, merge it into LibWebView.
A bit old but a relatively uncomplicated device capable of outputting
1920x1080 video with 32-bit color. Tested with a Voodoo 3 3000 16MB
PCI card. Resolution switching from DisplaySettings also works.
If the requested mode contains timing information, it is used directly.
Otherwise, display timing values are selected from the EDID. First the
detailed timings are checked, and then standard and established
timings for which there is a matching DMT mode. The driver does not
(yet) read the actual EDID, so the generic EDID in DisplayConnector now
includes a set of common display modes to make this work.
The driver should also be compatible with the Voodoo Banshee, 4 and 5
but I don't have these cards to test this with. The PCI IDs of these
cards are included as a commented line in case someone wants to give it
a try.
That API came from a mistake in the IDL compiler, where reflected
nullable attributes would try to call set_attribute(name, null).
This commit fixes the mistake in the IDL generator, and removes the
meaningless API.
This commit removes DeprecatedString's "null" state, and replaces all
its users with one of the following:
- A normal, empty DeprecatedString
- Optional<DeprecatedString>
Note that null states of DeprecatedFlyString/StringView/etc are *not*
affected by this commit. However, DeprecatedString::empty() is now
considered equal to a null StringView.
When the outline has focus, arrow keys navigate the outline instead
of changing the current page.
Add opt-up and opt-down as a way to move by one page even when the
outline has focus. (This matches Preview.app.)
xib change: Added two menu Previous Page with key equivalent opt-up
and Next Page with key equivalent opt-down to Go menu and bound them to
goToPreviousPage: and goToNextPage: on First Responder.
When the outline has focus, the responder chain is outline ->
window, so also add the actions on the window controller, and
let that forward to the PDF view.
When this feature was finally merged, the serenity_option in
lagom_options.cmake had the unintended side effect of always setting the
cache variable to "" in the initial cache. In order to actually set the
linker to use to be lld or mold, we need to set with the FORCE flag in
the use_linker.cmake file.
Found by checking with the CMake variable_watch() function.
This will stop the build from spamming the "Using LLD to link Lagom"
message all over the place :^)
Do this with INSTALL_INTERFACE genex include directory rules. We should
really standardize where the generated headers *actually* get installed
to though.
This allows the decoder to fail gracefully when reading a partial or
malformed TBSCertificate. We also now ensure that the certificate data
is valid before making a copy of it.
I broke this when moving from a xib file to creating the UI in code.
https://developer.apple.com/documentation/appkit/nsuserinterfaceitemidentification/1396829-identifier
says:
"Identifiers are used during window restoration operations to uniquely
identify the windows of the application. [...] If you create an item in
Interface Builder and do not set a value for this string, a unique value
is created for the item when the nib file is loaded. For
programmatically created views, you typically set this value after
creating the item but before adding it to a window."
Without this, encodeRestorableStateWithCoder: / restoreStateWithCoder:
in MacPDFView weren't getting called.
The documentation is very loud about cell-based things being
deprecated, but it's fairly hidden what to actually do to switch to
the non-deprecated way (implement a certain delegate method).
Session 120 from WWDC 2011 has some notes on this. Apple's official
site no longer seems to have that, but it's e.g. here:
https://docs.huihoo.com/apple/wwdc/2011/session_120__view_based_nstableview.pdf
Just setting headerView to nil removes the header, but also has
the effect of no longer drawing the outline view with a sidebar
background ¯\_(ツ)_/¯.
But also setting drawsBackground to NO on the scroll view restores
the sidebar look, so do that too.
With this, it is no longer necessar to explicitly set style.
The default NSTableViewStyleAutomatic now seems to resolve to
NSTableViewStyleSourceList, so stop explicitly setting it.
(This part has no behavior change.)
Clicking an item in the outline now opens that page.
This requires giving the outline view a delegate, which for some
reason also has th effect of indenting expandable items ¯\_(ツ)_/¯
The vertical alignment of text still looks off, though.
The outline has drawing artifacts, but it is somewhat functional:
You can click on disclosure triangles to open outline items, and
if the outline doesn't fit in the sidebar, it's scrollable.
The outline view has the correct sidebar look: gray with a slightly
transparent glass effect.
Clicking items doesn't have an effect yet.
This Just Works with NSToolbarSidebarTrackingSeparatorItemIdentifier,
as long as your window is has NSWindowStyleMaskFullSizeContentView
in its style mask. If it doesn't, things behave pretty weirdly and
at least in the docs I looked at, this requirement wasn't documented
at all :/
Anyways, switch MacPDFView to use safeAreaRect instead of bounds
now that we use NSWindowStyleMaskFullSizeContentView so that we
don't draw parts of the PDF under the title bar.
Also be careful to invalidate the PDF view if safeAreaRect changes,
so that the page is redrawn when toolbar visibility gets toggled.
- MacPDFWindowController is now the xib file's owner
- _pdfView moves over
- MacPDFWindowController is now the MacPDFViewDelegate and responsible
for updating the window's title
- Due to MacPDFWindowController now being the xib file's owner,
windowControllerDidLoadNib: is no longer called automatically,
so call a custom windowIsReady method manually instead
No behavior change.
I'd like to add a sidebar, and NSSplitViewItem apparently isn't
accessibly in .xib files without contortions. So I want to move
to creating the window in code, and this is a step towards that.
No behavior change.
These functions all have a very common case that can be dealt with a
very simple inline check, often avoiding the need to call an out-of-line
function. This patch moves the common case to inline functions in a new
ValueInlines.h header (necessary due to header dependency issues..)
8% speed-up on the entire Kraken benchmark :^)
For example, the locale "fr-FR" will have the preferred hour cycle list
of "H hB", meaning h23 and h12-with-day-periods. Whether date-times are
actually formatted with day-periods is up to the user, but we need to
parse the hour cycle as h12 to know that the FR region supports h12.
This bug was revealed by LibJS no longer blindly falling back to h12 (if
the `hour12` option is true) or h24 (if the `hour12` option is false).
We currently only return primary time zones, i.e. time zones that are
not a Link. LibJS will require knowledge of Link entries, and whether
each entry is or is not a Link.
This function must return true if the object may intercept and customize
access to indexed properties (properties where the property name is a
non-negative integer.)
This will be used to implement fast path optimizations for array-like
accesses in subsequent commits.
Which pretty much needs to be done together due to the amount of places
where they are compared together.
This also involves porting over StackOfOpenElements over to FlyString
from DeprecatedFly string to prevent a gazillion calls to
`.to_deprecated_fly_string` calls in HTMLParser.
This will effectively allow us to use C++ code as an input for the
compiler. This would be useful for testing, since otherwise we would
have had to specify tests as a spec-like XML, which is not exactly the
most developer-friendly experience.
The bots complain that `forward()` could be either from libc++'s
include/c++/v1/__utility/forward.h or from AK/StdLibExtras.h.
I don't see this locally, but Ladybird also defined AK_DONT_REPLACE_STD,
so let's see if this does the trick.
Use `Meta/serenity.sh build lagom MacPDF` to build, and either of
`open Build/lagom/bin/MacPDF.app` or
`Build/lagom/bin/MacPDF.app/Contents/MacOS/MacPDF` to run.
Xcode used to insert a bunch of things to Info.plist. Now it can
no longer do that, so manually put them there
1. main.m is now main.mm
2. MainMenu.xib is now no longer in a Base.lproj subfolder
3. Remove SerenityPDF.entitlements since it won't be used in our CMake
build
xib changes:
* Add a "Go" toplevel submenu
* Put a "Go to Page..." menu item in it
* Add showGoToPageDialog: to first responder
* Bind action of new menu item to that
The dialog is just a janky NSAlert for now.
This is a bit janky for several reasons:
* `initialize` is now no longer called on a bg thread
* sheet UI is janky both visually and from an implementation PoV
But hey, it works for now.
This works great when quitting and reopening the app,
but when closing a window and the reopening from Recent Files,
the current page isn't restored. In Preview.app, it is.
In the end, apparently I had "Close windows when quitting an
application" enabled in Desktop & Dock in System Settings. With that
turned off, it just worked (...but I still need to serialize the current
page in the view).
Even with it turned off, cmd-opt-q would "Quit and Keep Windows",
so I could've also used that for testing.
Automatic termination means that the app no longer shows up as
opened in the doc when the last Window is closed, but it's actually
still running and opens immediately when clicked again.
Sudden termination means that the app can close quickly on logout.
I think it means the runtime just calls _exit() and assumes all
data is saved continuously.
There are an unfortunate number of DeprecatedString conversions required
here, but these should all fall away and look much more pretty again
when other places are also ported away from DeprecatedString.
Leaves only the Element IDL interface left :^)
This isn't included in the base definition of a CSS-wide keyword, but
the CASCADE-4 spec which adds it says:
> The revert CSS-wide keyword rolls back the cascade to the cascaded
value of the earlier origin.
So it is one. While I'm at it, rename `is_builtin()` to match the spec
terminology. It's not used currently, but will be in the next commit.
For now, part of this is commented-out. Our current implementations of
`<mask>` and `<symbol>` rely on creating layout nodes, so they can't be
`display: none`.
And implement WindowProperties, the "named properties object" for Window
according to the spec.
This involves moving an AO out of LegacyPlatformObject and into a common
place that the WindowProperties class can access.
This doesn't implement the AOs on Window that actually name lookup for
the unenumerable named properties on the window yet, just the
scaffolding.
The `to_string()` for this is modified a little from the original,
because we have to calculate what the layer-count is then, instead of
having it already calculated.
Support for this element has been removed from all major engines years
ago already, and it's currently the only reason we have a weird
"visible" flag on Layout::Node (which we toggle on a timer here..)
This flag makes the linker bind default-visibility functions locally, so
that calls to them do not have to go through the PLT. This makes it
impossible to override them by preloading a DSO. This was already the
case partially due to `-fno-semantic-interposition`, however that flag
is only able to optimize call sites that are in the same Translation
Unit as the function definitions.
This removes 80% of the PLT relocations in `libjs.so.serenity`.
Obsoletes #20877
This makes CMake pass `-fpie` instead of `-fpic` to the compiler when
building the Kernel and userland *executables*. This allows the compiler
to make certain optimizations based on the fact that the code will be
used in an executable, such as not having to emit `.localalias` symbols.
This leads to a 450 KiB decrease in the size of the Kernel binary.
The FileReader IDL has the following entry:
```
readonly attribute (DOMString or ArrayBuffer)? result;
```
This change supports the use ArrayBuffer as a JS built-in in this
definition.
https://unicode.org/versions/Unicode15.1.0/
This update includes a new set of code point properties, Indic Conjunct
Break. These may have the values Consonant, Linker, or Extend. These are
used in text segmentation to prevent breaking on some extended grapheme
cluster sequences.
In bd7d01e9, Meta/serenity.sh started checking cc and cxx if CC or CXX
respectively are not set in the environment. My machine does not have
cxx symlink in PATH, so every invocation of the script resulted in
the "cxx: command not found" message outputted to stderr, and that
became quite annoying.
It simplifies ladders of BinaryOperators nodes in the function call
arguments into nice and neat FunctionCall node. Ladders initially appear
since I do not want to complicate expression parser, so it interprets
`f(a, b, c, d)` as `f "function_call_operator" (a, (b, (c, d))))`.
This class stores a non-owning raw pointer to a member of `Node`, so
extra care is needed to ensure that referenced `Node`s will be alive
by the time `NodeSubtreePointer` is used. Since we only need to use this
class while traversing AST in `RecursiveASTVisitor`, access to class
methods can be restricted using `Badge<RecursiveASTVisitor>`.
Previously if the IDL was something like:
```
constructor(optional DOMString data = "");
```
We were generating code that would be passing through to the constructor
an Optional<String> - even though for this situation it is not possible
for it to be null.
Instead, if we know if there is a default value that is non-null and the
type is not nullish, just generate the cpp code as a String.
This change allows IDL interfaces to be compiled using new AK String
which have a attribute in the interface that may return null.
Without this change we would run into a compile error from code such as
the following example:
```
auto retval = impl->deprecated_attribute(HTML::AttributeNames::ref);
if (!retval.has_value()) {
return JS::js_null();
}
return JS::PrimitiveString::create(vm, retval.release_value());
```
As `deprecated_attribute` returns a `DeprecatedString` instead of an
`Optional<String>`. Fix that by using the non-deprecated attribute
implementation, and falling back to the empty string for where we cannot
return null.
Also add a test here to cover a regression I almost introduced here
which was not previously covered by our test suite.
Ideally, all of this should actually just be calling
Element::get_attribute_value, but I'm not entirely sure at this stage
what the behavioral change would be to test for here. Since this
implementation preserves the previous behavior, stick with it, and add a
FIXME for now.
This should allow us to add a Element::attribute which returns an
Optional<String>. Eventually all callers should be ported to switch from
the DeprecatedString version, but in the meantime, this should allow us
to port some more IDL interfaces away from DeprecatedString.
This ports over the `LADYBIRD_USE_LLD` option from the standalone
Ladybird build and generalizes it to work for mold as well: the
`LAGOM_USE_LINKER` variable can be set to the desired name of the
linker. If it's empty, we default to trying LLD and Mold on ELF
platforms (in this order).
We currently only use frame pointer-based backtrace generation.
This option is necessary for RISC-V as otherwise the compiler doesn't
save `fp` most of the time.
I made this flag not riscv64 exclusive, as we should do everything
to make that kind of backtrace generation work.
(https://discord.com/channels/830522505605283862/1139481927594803260/1148020960499351643)
This template app from Android Studio should hopefully be more fun to
work on than the Qt wrapped application we were using before. :^)
It currently builds the native code using gradle rules, and has a stub
WebViewImplementationNative class that will wrap a c++ class of the same
name that inhertis from WebView::ViewImplementation. Spawning helper
processes and creating proper views in Kotlin is next on the list.
NewAKString is effectively the default for any new IDL interface, so
let's mark this as the default behavior. It also makes it much easier to
figure out whatever interfaces are still left to port over to new AK
String.
Currently, they are not extremely useful, but the plan is to store
all function-local state in JSSpecCompiler::Function and all
"translation unit" state in ExecutionContext.
On platforms that support it, enable using ``<execinfo.h>`` to get
backtrace(3) to dump a backtrace on assertion failure. This should make
debugging things like WebContent crashes in Lagom much easier.
Previously, we always assumed that local includes are relative to the
parent directory of a file. This effectively banned style-wise
multi-directory subprojects which are not libraries, since there was no
way to cleanly reference local file from a different directory.
This commit relaxes the restrictions by introducing
LOCAL_INCLUDE_ROOT_OVERRIDES. Entry in the set changes root of the
local includes to itself for all files in its subtree.
This creates WebView::ConsoleClient to handle functionality that will be
common to the JS consoles of all Ladybird chromes. This will let each
chrome focus on just the UI.
Note that this includes the `console.group` functionality that only the
Serenity chrome previously had. This was a FIXME in the Qt chrome, and
it is implemented such that all chromes will receive this functionality
for free.
This tokenizes a page's source to produce HTML with syntax highlighting.
The first implementation here is rather simple; we do not yet implement
code folding, line numbers, etc.
The goal is for this to be used as the View Source implementation for
all Ladybird chromes.
Move the methods to set the native/user style sheets to the base
ViewImplementation class. We must also generate the native style sheet
explicitly for now, as LibWebView on Lagom isn't able to include the
main LibWebView CMakeLists.txt file yet.
This event is the star of the show, and the main way that web content
can react to either programmatic or user-initiated navigation.
All of the fun algorithms will have to come later though.
This API is how JavaScript can manipulate the new Navigable concepts
directly. We are still missing most of the interesting algorithms on
Navigation that do the actual navigation steps, and call into the
currently WIP navigable AOs.
Add some checks to the statement wrapping code to make sure we properly
handle the expected pattern of returning ``Optional<Enum>`` from
nullable enum properties.
These APIs only perform small allocations, and are only used by LibJS.
Callers which could only have failed from these APIs are also made to
be infallible here.

This adds an alternative Ladybird chrome for macOS using the AppKit
framework. Just about everything needed for normal web browsing has
been implemented. This includes:
* Tabbed, scrollable navigation
* History navigation (back, forward, reload)
* Keyboard / mouse events
* Favicons
* Context menus
* Cookies
* Dialogs (alert, confirm, prompt)
* WebDriver support
This does not include debugging tools like the JavaScript console and
inspector, nor theme support.
The Qt chrome is still used by default. To use the AppKit chrome, set
the ENABLE_QT CMake option to OFF.
This interface is used in the interface for HTMLFormControlsCollection
as a live view over its matching elements.
Currently the "value" attribute for this interface is left
unimplemented.
This makes it possible to specify (instead of is_debug) a more
specialized is_debug_lldb or is_debug_gdb, so that clang outputs the
proper symbols. (For lldb this fixes issues with formatting by
setting -fstandalone-debug)
By running ctest -C Integration -R WPT, you can run WPT. Adding just
-C Integration will run all other tests *and* the WPT test.
Also add support for ./Meta/serenity.sh test lagom WPT to serenity.sh
We should be documenting required pacakges elsewhere and installing them
in the setup step of CI.
This also fixes a problem where the run script would fail if you already
had a cloned wpt directory.
The proper syntax for defining user-defined literals does not require a
space between the `operator""` token and the operator name:
> error: identifier 'sv' preceded by whitespace in a literal operator
> declaration is deprecated
This is a minimal set of changes to allow `serenity.sh build riscv64` to
successfully generate the build environment and start building. This
includes some, but not all, assembly stubs that will be needed later on;
they are currently empty.
LibC is always guaranteed to be loaded at program start, so its
thread-local variables live in the static TLS block. This permits us to
use the more optimal initial-exec TLS access model.
IFF was a generic container fileformat that was popular on the Amiga
since it was the only file format supported by Deluxe Paint.
ILBM is an image format popular in the late eighties/nineties
that uses the IFF container.
This is a very first version of the decoder that only supports
(byterun) compressed files with bpp <= 8.
Only the minimal chunks are decoded: CMAP, BODY, BMHD.
I am planning to add support for the following variants:
- EHB (32 colours + lighter 32 colours)
- HAM6 / HAM8 (special mode that allowed to display the whole Amiga
4096 colours / 262 144 colours palette)
- TrueColor (24bit)
Things that could be fun to do:
- Still images could be animated using color cycle information
Stop worrying about tiny OOMs. Work towards #20449.
While going through these, I also changed the function signature in many
places where returning ThrowCompletionOr<T> is no longer necessary.
The test runner script sets the `halt_on_error=1` `UBSAN_OPTIONS` flag
already, this just makes it a compile-time decision. This should
alleviate some of the slowness of running on-target tests without
hardware acceleration.
Instead of hardcoding bin/, we should use the INSTALL_BINDIR directly
to reflect the intent of the way we're doing the settings.
This should have the benefit of fixing the build when a distro sets the
GNUInstallDirs variables to exciting values, like on NixOS.
This is accomplished by detecting the Userland subdirectory from the GML
file's own path. Thereby, any Userland program, e.g. applet,
application, or even service, can use GML and the include paths of the
generated files will be correct.
As with other special cases, this depends on the property name.
The UIDimension code is kept separate since it can handle both integers
and strings, and the string names for special dimensions don't match
with the enum names.
This encoder can handle all integer formats and sample rates, though
only two channels well. It uses fixed LPC and performs a
close-to-optimal parameter search on the LPC order and residual Rice
parameter, leading to decent compression already.
I couldn't run the parser in a debugger like I normally would, so I
added printouts to understand where the parser is failing.
More could be added, but these are enough to get a good idea of what
the parser is doing. It's very spammy, though, so enable it by flicking
the IMAP_PARSER_DEBUG switch :^)
Two non-functional changes:
- Remove pointless `-latomic` flag. It was specified via
`add_compile_options`, which only affects compilation and not linking,
so the library was never actually linked into the kernel. In fact, we
do not even build `libatomic` for our toolchain.
- Do not disable `-Wnonnull`. The warning-causing code was fixed at some
point.
This commit also removes `-mstrict-align` from the userland. Our target
AArch64 hardware natively supports unaligned accesses without a
significant performance penalty. Allowing the compiler to insert
unaligned accesses into aligned-as-written code allows for some
performance optimizations in fact. We keep this option turned on in the
kernel to preserve correctness for MMIO, as that might be sensitive to
alignment.
We now apply MathML's default user agent style sheet along with other
default styles. This sheet is not mixed in with the other styles in
CSS/Default.css because it is a namespaced stylesheet and so has to
be its own sheet.
This does the exact same thing as the runtime initializer,
except it is faster and can catch some errors much earlier.
The code generator includes these important features:
- Automatic include generation where necessary
- Special-casing for TabWidget and ScrollableContainerWidget
- No use of DeprecatedString where possible
We weren't installing a lot of generated sources for the top level Lagom
build or for LibWeb, making it impossible to use LibWeb from a
find_package. ...And also Kernel/API/KeyCode.h, which is included by
no less than 8 different files in Userland/Libraries. We also weren't
installing any Ladybird header files.
