# Objective Make `bevy_error_panic_hook` threadsafe. As it relies on a global variable, it fails when multiple threads panic. ## Solution Switch from a global variable for storing whether an error message was printed to a thread-local one. `thread_local` is in `std`; the `backtrace` already relies on `std` APIs. It didn't depend on the `std` feature though, so I've added that. I've also put `bevy_error_panic_hook` behind the `backtrace` feature, since it relies on the thread local variable, which fixes #18231. ## Testing The following now loops instead of crashing: ```rust std:🧵:scope(|s| { use bevy_ecs::error::*; #[derive(Debug)] struct E; impl std::fmt::Display for E { fn fmt(&self, _: &mut std::fmt::Formatter<'_>) -> std::fmt::Result { todo!() } } impl std::error::Error for E {} std::panic::set_hook(Box::new(bevy_error_panic_hook(|_| { unreachable!(); }))); for _ in 0..2 { s.spawn(|| { loop { let _ = std::panic::catch_unwind(|| { panic!("{:?}", BevyError::from(E)); }); } }); } }); ```

# Functionality
|
|
|
|
## Enables multithreading support. Schedules will attempt to run systems on
|
|
## multiple threads whenever possible.
|
|

## Adds serialization support through `serde`.

|
## Adds runtime reflection support using `bevy_reflect`.
|
|

|
|
|
## Extends reflection support to functions.
|
|

|
## Use the configurable global error handler as the default error handler
|
|

# Debugging Features

|
## Enables `tracing` integration, allowing spans and other metrics to be reported
|
|
## through that framework.
|

trace = ["std", "dep:tracing"]
|
|
|
|
## Enables a more detailed set of traces which may be noisy if left on by default.
|
|

## Provides system stepping support, allowing them to be paused, stepped, and
|
|
## other debug operations which can help with diagnosing certain behaviors.

# Executor Backend

# Platform Compatibility

|
## on `no_std` targets, but provides access to certain additional features on

|
## supported platforms.
