Everything but signal handlers has been changed to use `Signal` instead of
`c_int` or `i32` signal values.
Event handlers are using `usize` to match C++, at least for now.
Signal is a newtype around NonZeroI32. We could use NonZeroU8 since all signal
values comfortably fit, but using i32 lets us avoid a fallible attempt at
narrowing values returned from the system as integers to the narrower u8 type.
Known signals are explicitly defined as constants and can be matched against
with equality or with pattern matching in a `match` block. Unknown signal values
are passed-through without causing any issues.
We're using per-OS targeting to enable certain libc SIGXXX values - we could
change this to dynamically detecting what's available in build.rs but then it
might not match what libc exposes, still giving us build failures.
This should be used in lieu of manually targeting individual operating systems
when using features shared by all BSD families.
e.g. instead of
#[cfg(any(target_os = "freebsd", target_os = "dragonflybsd", ...))]
fn foo() { }
you would use
#[cfg(feature = "bsd")]
fn foo() { }
This feature is automatically detected at build-time (see build.rs changes) and
should *not* be enabled manually. Additionally, this feature may not be used to
conditionally require any other dependency, as that isn't supported for
auto-enabled features.
Another from the "why are we asserting instead of doing something
sensible" department.
The alternative is to make exit() and return() compute their own exit
code, but tbh I don't want any *other* builtin to hit this either?
Fixes#9659
Just address two clippy lints that are fallout from changing the signal type.
There's no longer any need to convert these (which gets rid of an unwrap).
Due to limitations imposed by the borrow checker, there are very few places
where we will be able to use the `ScopedPush` class ported over from the C++
codebase (once you capture the value w/ a `ScopedPush` you can't access the
value - or the mutable reference you used to reach it! - until the `ScopedPush`
object goes out of scope).
This alternative requires binding the previous values to a variable and manually
restoring them in the callback passed to the `ScopeGuard` constructor, but will
work with rust's borrow and `&mut` paradigm.
Currently the `autocxx` generated code does not produce any code intelligence
because `rust-analyzer` can't find the generated code since it's not in the
workspace. Here, we detect `rust-analyzer` by checking for a `RUSTC_WRAPPER`
environment variable containing `rust-analyzer` and changing (or avoid changing)
the output directory accordingly.
Closes#9654.
This was added to support signals; however we are unlikely to use this
for anything else. Remove it; just use a u64 to report signals that have
been set.
The test passes but only if executed on its own. It's not the most perfect test,
but I can basically never get `make test` to pass under WSL while that's not the
case on all my other machines.
This optimizes over both the rust rewrite and the original C++ code. The rust
rewrite saw `std::bitset` replaced with `[bool; 65]` which could result in a
lot of memory copy bandwidth each time we checked for and received no signals.
The original C++ code would iterate over all signal slots to see if any were
set. The code now returns a single u64 and only checks slots that are known to
have signals via an intelligent `Iterator` impl.
You can now use a reference to CxxWString or an allocated UniquePtr<CxxWString>
to get an &wstr temporary to use without having to allocate again (e.g. via
`from_ffi()`).

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.
