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.
wchar.rs should not import let alone reexport FFI strings.
Stop re-exporting utf32str! because we use L! instead.
In wchar_ffi.rs, stop re-exporting cxx::CxxWString because that hasn't
seen adoption.
I think we should use re-exports only for aliases like "wstr" or for aliases
into internal modules.
So I'd probably remove `pub use wchar_ffi::wcharz_t = crate::ffi::wcharz_t`
as well.
bool_assert_comparison is stupid, the reason they give is "it's shorter". Well,
`assert!(!foo)` is nowhere near as readable as `assert_eq!(foo, false)` because
of the ! noise from the macro.
Uninlined format args is a stupid lint that Rust actually walked back when they
made it an official warning because you still have to use a mix of inlined and
un-inlined format args (the latter of which won't complain) since only idents
can be inlined.
This shows some of the ugliness of the rust borrow checker when it comes to
safely implementing any sort of recursive access and the need to be overly
explicit about which types are actually used across threads and which aren't.
We're forced to use an `Arc` for `ItemMaker` (née `item_maker_t`) because
there's no other way to make it clear that its lifetime will last longer than
the FdMonitor's. But once we've created an `Arc<T>` we can't call
`Arc::get_mut()` to get an `&mut T` once we've created even a single weak
reference to the Arc (because that weak ref could be upgraded to a strong ref at
any time). This means we need to finish configuring any non-atomic properties
(such as `ItemMaker::always_exit`) before we initialize the callback (which
needs an `Arc<ItemMaker>` to do its thing).
Because rust doesn't like self-referential types and because of the fact that we
now need to create both the `ItemMaker` and the `FdMonitorItem` separately
before we set the callback (at which point it becomes impossible to get a
mutable reference to the `ItemMaker`), `ItemMaker::item` is dropped from the
struct and we instead have the "constructor" for `ItemMaker` take a reference to
an `FdMonitor` instance and directly add itself to the monitor's set, meaning we
don't need to move the item out of the `ItemMaker` in order to add it to the
`FdMonitor` set later.
We were only using their ffi implementations which are automatically
exported/public, but the actual functions we would need if we were to use
FdMonitor and co. in native rust code were either private or missing convenient
wrappers.
The existing code is kept, but a rusty version of these functions is added for
code that needs them.
These should only be temporarily used when porting 1-to-1 from C++; we should
use the std library's `read()` and `write_all()` methods instead in the future.
By extracting the equivalent of i32::cmp() into its own const function,
it becomes a lot easier to see what is happening and the logic can be
more direct.
These will be used in the parser.
Maybe this type should be a struct with boolean fields. The current way has
the upside that the usage is exactly the same as in C++.
CXX does not allow generic types like maybe_t. When porting a C++ function
that returns maybe_t to Rust, we return std::unique_ptr instead. Let's make
the transition more seamless by allowing to convert back to maybe_t implicitly.
For some reason this error is triggered by tests after the Rust port of
ast.cpp. Might want to get to the bottom of this but moving it back
to match the original C++ logic fixes it.
This is one of the few warnings we disable due to false positives. Let's also
disable it in the preprocessing steps needed for the Rust build.
Other warnings we ignore are -Wno-address -Wunused-local-typedefs and
-Wunused-macros. I didn't add them here because I don't expect that they
will be triggered by the headers we give to cxx.
