They are probably not terribly useful for us but let's see what happens.
Unfortunately cargo does not properly forward the combination of "RUSTFLAGS"
and "--target" that is currently required to build with ASan [1]. Hence doctests
will fail to link on ASan builds. Let's disable doctests when ASan is active.

Use Rust for executables
Drops the C++ entry points and restructures the Rust package into a
library and three binary crates.
Renames the fish-rust package to fish.
At least on Ubuntu, "fish_indent" is built before "fish".
Make sure export CURSES_LIBRARY_LIST to all binaries to make sure
that "cached-curses-libnames" is populated.
Closes#10198
This makes "ninja test" write only to the build directory, not to the source
tree. This enables our docker script which mounts the source as read-only.
GNUInstallDirs is what defines CMAKE_INSTALL_FULL_BINDIR and such, so
the setting in Rust.cmake didn't work.
This also makes build.rs error out if any of these aren't defined
Keep running tests serially to avoid breaking assumptions.
I think many of these tests can run in parallel and/or don't need test_init().
Use the safe variant everywhere, to get it done faster.
This will allow to use "cargo test" for unit tests that depend on our
curses.rs.
This means that Rust.cmake depends on ConfigureChecks, so move that one to
the front.
- Make CMake use the correct target-path
- Make build.rs use the correct target dir
Workspaces place it in the project root by default, the alternative to making
this change is to add a `.cargo/config.toml` file with
```toml
[build]
target-dir = "fish-rust/target"
```
Which I think is unnecessary, as we likely want to use the new location anyways.
Corrosion does not forward the `CMAKE_OSX_DEPLOYMENT_TARGET` to cargo.
As a result we end up building the Rust-libraries for the default target,
which is usually current macOS-version. But CMake links using the set
target, so we link for a version older than we built for.
To properly build for older macOS versions, the env variable
`MACOSX_DEPLOYMENT_TARGET` should instead be set, which cargo,
cmake and friends read by default. This can then lead to
warnings if you have libraries (e.g. PCRE2) built for newer
than our minimum version. Therefore we do not set a min-target
by default.
Remove the following C++ functions/methods, which have no callers:
fallback.cpp:
- wcstod_l
proc.cpp:
- job_t::get_processes
wutil.cpp:
- fish_wcstoll
- fish_wcstoull
Also drop unused configure checks/defines:
- HAVE_WCSTOD_L
- HAVE_USELOCALE
This is more complicated than it needs to be thanks to the presence of CMake and
the C++ ffi in the picture. rsconf can correctly detect the required libraries
and instruct rustc to link against them, but since we generate a static rust
library and have CMake link it against the C++ binaries, we are still at the
mercy of CMake picking up the symbols we want.
Unfortunately, we could detect the gettext symbols but discover at runtime that
they weren't linked in because CMake was compiled with `-DWITH_GETTEXT=0` or
similar (as the macOS CI runner does). This means we also need to pass state
between CMake and our build script to communicate which CMake options were
enabled.
The new asan exit handlers are called to get proper ASAN leak reports (as
calling _exit(0) skips the LSAN reporting stage and exits with success every
time).
They are no-ops when not compiled for ASAN.
Use a "cmake-vendored" directory if it exists, to avoid accessing the
network if it's available, and a target to create an appropriate tarball
to create that directory.
Rust has multiple sanitizers available (with llvm integration).
-Zsanitizer=address catches the most likely culprits but we may want to set up a
separate job w/ -Zsanitizer=memory to catch uninitialized reads.
It might be necessary to execute `cargo build` as `cargo build -Zbuild-std` to
get full coverage.
When we're linking against the hybrid C++ codebase, the sanitizer library is
injected into the binary by also include `-fsanitize=address` in CXXFLAGS - we
do *not* want to manually opt-into `-lasan`. We also need to manually specify
the desired target triple as a CMake variable and then explicitly pass it to all
`cargo` invocations if building with ASAN.
Corrosion has been patched to make sure it follows these rules.
The `cargo-test` target is failing to link under ASAN. For some reason it has
autocxx/ffi dependencies even though only rust-native, ffi-free code should be
tested (and one would think the situation wouldn't change depending on the
presence of the sanitizer flag). It's been disabled under ASAN for now.
The FISH_RUST_TARGET_DIR is not set for Tests.cmake, the target_dir will set to
$CARGO_MANIFEST_DIR/target. But if build.target-dir or CARGO_TARGET_DIR is set,
the real target_dir doesn't at the $CARGO_MANIFEST_DIR/target. It causes failure
in cargo test. Then, set --target-dir for cargo test.
Closes#9600
a lynx-internal hash of div.contents collided with em>a which caused
built-in styling to render much of entire pages as emphasized links.
Since switching from doxygen, we haven't had a <div class="contents">
so this workaround is no longer needed.
The previous check was including these as relative includes, meaning the actual
system header files weren't actually being explicitly included and the check
could spuriously fail.
CMAKE_EXTRA_INCLUDE_FILES doesn't seem to have a way to specify that the
includes should be treated as system/global includes and CHECK_TYPE_SIZE() isn't
documented as being affected by any other variables that do, so switch to
another method altogether.
This requires that `struct winsize` have a member `ws_row`, but as best as I can
tell that is always the case.
Closes#9279.
g++ 4.8 emits a bogus warning on code like foo{}. Add a compiler flag
-Wno-missing-field-initializers if that warning is detected, because it
is annoying.
GIT_WORK_TREE is an environment variable which tells git where the
worktree is. It may be set by the user or by git itself, e.g. when
running `git rebase -i --exec ...`. If it is set, it overrides the
working directory, causing the `git checkout` from FetchContent_Populate
to fail. Clear this variable.
Do the same for GIT_DIR for the same reason.
A way to reproduce the failure that this commit fixes is:
git rebase -i HEAD^^^ --exec 'ninja -C /path/to/build/dir fish'
prior to this commit, using the fetched PCRE2, this would fail in CMake.
