This change removes wrappers inherited from Gfx::Typeface for WOFF and
WOFF2 fonts. The only purpose they served is owning of ttf ByteBuffer
produced by decoding a WOFF/WOFF2 font. Now new FontData class is
responsible for holding ByteBuffer when a font is constructed from
non-externally owned memory.
Override the vcpkg/scripts/detect_compiler behavior of always pulling
$CC and $CXX at the time that vcpkg install is determined to need called
by forcing $ENV{CXX} and $ENV{CC} to our CMake-determined compiler.
This prevents strange behavior such as running the following:
./Meta/ladybird.sh run
make changes...
ninja -C Build/ladybird
Where the second build step would be run without CC or CXX set in the
environment, causing a total cache miss from vcpkg and a full rebuild.
It also helps prevent full rebuilds when an IDE passes a slightly
different compiler to the build step than ladybird.sh.
AK will depend on some vcpkg dependencies, so the Lagom tools build will
need to know how to use vcpkg. We can do this by sym-linking vcpkg.json
to Meta/Lagom (as vcpkg.json has to be in the CMake source directory).
We also need a CMakePresets.json in the source directory, which can just
include the root file. The root CMakePresets then needs to define paths
relative to ${fileDir} rather than ${sourceDir}.
- `-fstack-protection-strong` enables stack canaries for functions where
addresses of local variables are taken or arrays/structures
containing arrays are allocated on the stack.
- `-fstrict-flex-arrays=2` causes the compiler to only treat arrays with
unknown bounds (`[]`) or zero-length-arrays (`[0]`) as *flexible array
members*, allowing the sanitizers to emit bounds checks for structs
with proper arrays as their last member.
More rigorous options (such as AArch64 pointer authentication, Control
Flow Integrity, _FORTIFY_SOURCE) should be investigated in the future,
however this is a good baseline.
If no header includes the prototype of a function, then it cannot be
used from outside the translation unit it was defined in. In that case,
it should be marked as `static`, in order to avoid possible ODR
problems, unnecessary exported symbols, and allow the compiler to better
optimize those.
If this warning triggers in a function defined in a header, `inline`
needs to be added, otherwise if the header is included in more than one
TU, it will fail to link with a duplicate definition error.
The reason this diff got so big is that Lagom-only code wasn't built
with this flag even in Serenity times.
These used to be enabled in `serenity_compile_options.cmake` for
Serenity builds and were removed in 9b05fb98. This is a slightly more
conservative subset of those, with ones that are enabled by default
omitted.
This should prevent our code quality regressing in the long run.
This change updates the Meta/check-debug-flags.sh script to avoid an
apparent Bach 3.2 parser bug. Specifically, it takes a comment and some
code of a process substitution and moves it into a separate function.
Otherwise, without this change, trying to run the check-debug-flags.sh
script with Bash 3.2 fails with the following error:
line 39: bad substitution: no closing `)' in <(
...apparently because Bash 3.2 chokes on the comment (and doesn’t choke
if the comment is completely removed).

This change makes all the pre-commit CI scripts runnable under Bash 3.2,
by replacing “mapfile” invocations in them code that first explicitly
creates an array, and then uses a while loop to populate the array.
Otherwise, without this change, the scripts all fail to run under Bash
3.2 — due to lack of support for “mapfile”.
Fixes https://github.com/LadybirdBrowser/ladybird/issues/283
This also drops bash from the list of homebrew dependencies in the build
instructions — because with this change, homebrew bash (v4) is no longer
needed; things will now work with the Apple-provided bash (v3.2)
We no longer have multiple locations including AK (e.g. LibC). So let's
avoid awkwardly defining the AK library across multiple CMake files.
This is to allow more easily adding third-party dependencies to AK in
the future.
Since we support the multi-memory proposal, we should skip tests that
validate that we have only one memory. Once multi-memory gets included
in the main WebAssembly specification (and the testsuite is updated), we
can revert this commit.
Because `nan:arithmetic` and `nan:canonical` aren't bound to a single
bit pattern, we cannot check against a float-containing SIMD vector
against a single value in the tests. Now, we represent `v128`s as
`TypedArray`s in `testjs` (as opposed to using `BigInt`s), allowing us
to properly check `NaN` bit patterns.
Some spec-tests check the bit pattern of a returned `NaN` (i.e.
`nan:canonical`, `nan:arithmetic`, or something like `nan:0x200000`).
Previously, we just accepted any `NaN`.
`linking.wast` has an unusual pattern for invoke commands, which is now
accounted-for. Also, special unicode characters are now properly
serialized in JavaScript as string literals (this is only relevant for
`names.wast`).
Trying to build VulkanLoader from source is a giant headache of
unnecessary packages. Every modern distro has vulkan packages, let's
depend on those instead of trying to build something for both wayland
and X11.
We need to avoid using vcpkg's pkg-config on non-x86_64 platforms,
because they do very strange things to the default paths.
On Asahi Linux and other 16 KiB page distros, the user must also provide
a properly compiled version of GN.
This commit replaces all TLS connection code with wolfssl.
The certificate parsing code has to remain for now, as wolfssl does not
seem to have any exposed API for that.
