# Objective
- Contributes to #15460
## Solution
- Added the following features:
- `std` (default)
- `async_executor` (default)
- `edge_executor`
- `critical-section`
- `portable-atomic`
- Added [`edge-executor`](https://crates.io/crates/edge-executor) as a
`no_std` alternative to `async-executor`.
- Updated the `single_threaded_task_pool` to work in `no_std`
environments by gating its reliance on `thread_local`.
## Testing
- Added to `compile-check-no-std` CI command
## Notes
- In previous iterations of this PR, a custom `async-executor`
alternative was vendored in. This raised concerns around maintenance and
testing. In this iteration, an existing version of that same vendoring
is now used, but _only_ in `no_std` contexts. For existing `std`
contexts, the original `async-executor` is used.
- Due to the way statics work, certain `TaskPool` operations have added
restrictions around `Send`/`Sync` in `no_std`. This is because there
isn't a straightforward way to create a thread-local in `no_std`. If
these added constraints pose an issue we can revisit this at a later
date.
- If a user enables both the `async_executor` and `edge_executor`
features, we will default to using `async-executor`. Since enabling
`async_executor` requires `std`, we can safely assume we are in an `std`
context and use the original library.

# Objective
- Contributes to #15460
## Solution
- Added the following new features:
- `std` (default)
- `alloc`
- `encase` (default)
- `libm`
## Testing
- Added to `compile-check-no-std` CI command
## Notes
- `ColorCurve` requires `alloc` due to how the underlying `EvenCore`
type works.
- `Srgba::to_hex` requires `alloc` to return a `String`.
- This was otherwise a _very_ simple change
# Objective
- Contributes to #15460
## Solution
- Added `std` feature (enabled by default)
## Testing
- CI
- `cargo check -p bevy_reflect --no-default-features --target
"x86_64-unknown-none"`
- UEFI demo application runs with this branch of `bevy_reflect`,
allowing `derive(Reflect)`
## Notes
- The [`spin`](https://crates.io/crates/spin) crate has been included to
provide `RwLock` and `Once` (as an alternative to `OnceLock`) when the
`std` feature is not enabled. Another alternative may be more desirable,
please provide feedback if you have a strong opinion here!
- Certain items (`Box`, `String`, `ToString`) provided by `alloc` have
been added to `__macro_exports` as a way to avoid `alloc` vs `std`
namespacing. I'm personally quite annoyed that we can't rely on `alloc`
as a crate name in `std` environments within macros. I'd love an
alternative to my approach here, but I suspect it's the least-bad
option.
- I would've liked to have an `alloc` feature (for allocation-free
`bevy_reflect`), unfortunately, `erased_serde` unconditionally requires
access to `Box`. Maybe one day we could design around this, but for now
it just means `bevy_reflect` requires `alloc`.

# Objective
- Contributes to #15460
## Solution
- Added two new features, `std` (default) and `alloc`, gating `std` and
`alloc` behind them respectively.
- Added missing `f32` functions to `std_ops` as required. These `f32`
methods have been added to the `clippy.toml` deny list to aid in
`no_std` development.
## Testing
- CI
- `cargo clippy -p bevy_math --no-default-features --features libm
--target "x86_64-unknown-none"`
- `cargo test -p bevy_math --no-default-features --features libm`
- `cargo test -p bevy_math --no-default-features --features "libm,
alloc"`
- `cargo test -p bevy_math --no-default-features --features "libm,
alloc, std"`
- `cargo test -p bevy_math --no-default-features --features "std"`
## Notes
The following items require the `alloc` feature to be enabled:
- `CubicBSpline`
- `CubicBezier`
- `CubicCardinalSpline`
- `CubicCurve`
- `CubicGenerator`
- `CubicHermite`
- `CubicNurbs`
- `CyclicCubicGenerator`
- `RationalCurve`
- `RationalGenerator`
- `BoxedPolygon`
- `BoxedPolyline2d`
- `BoxedPolyline3d`
- `SampleCurve`
- `SampleAutoCurve`
- `UnevenSampleCurve`
- `UnevenSampleAutoCurve`
- `EvenCore`
- `UnevenCore`
- `ChunkedUnevenCore`
This requirement could be relaxed in certain cases, but I had erred on
the side of gating rather than modifying. Since `no_std` is a new set of
platforms we are adding support to, and the `alloc` feature is enabled
by default, this is not a breaking change.

# Objective
- Fix bug where `cargo run -p ci` fails due to differing implementations
for default values between `Default` trait and `argh`
- Automatically install target via `rustup` to make first-run simpler.
## Solution
The command will now attempt to install the target via `rustup` by
default, which will provide a cleaner error message if a malformed
target is passed. It will also avoid confusion when people attempt to
use this tool for the first time without the target already installed.
I've added a flag, --skip-install, to disable the attempted installation
just-in-case. (e.g., maybe rustup isn't in their path but cargo is?).
Also fixed a bug where the default value for `target` was different
between the `Default` trait and `argh`, causing `cargo run -p ci` to
fail.
## Testing
- CI
- Subcommand ran directly
## Notes
This issue was originally discovered by @targrub (on Discord):
> Unfortunately, running `cargo run -p ci` still gives that same error
as I initially reported (though `cargo run -p ci --
compile-check-no-std` succeeds). This is after having run `rustup target
add x86_64-unknown-none`.
# Objective
- Fixes#15840
## Solution
Added a new subcommand to the CI tool, `compile-check-no-std`, which
will attempt to compile each `no_std` crate in Bevy with the appropriate
features (no-defaults, `libm`, etc.) for `x86_64-unknown-none`. The
exact target chosen could be changed to any reasonable platform which
does not include the `std` library.
The currently tested crates are:
- `bevy_ptr`
- `bevy_utils`
- `bevy_mikktspace`
As more crates have `no_std` support added, they _should_ be added to
this CI command. Once Bevy itself can be `no_std`, the individual checks
can be replaced with just checking Bevy, since it will transiently check
all other crates as appropriate.
## Testing
- Ran CI. From a clean target directory (`cargo clean`), these new
checks take approximately 10 seconds total.

# Objective
- Bevy currently has lot of invalid intra-doc links, let's fix them!
- Also make CI test them, to avoid future regressions.
- Helps with #1983 (but doesn't fix it, as there could still be explicit
links to docs.rs that are broken)
## Solution
- Make `cargo r -p ci -- doc-check` check fail on warnings (could also
be changed to just some specific lints)
- Manually fix all the warnings (note that in some cases it was unclear
to me what the fix should have been, I'll try to highlight them in a
self-review)
# Objective
- Follow-up of #13184 :)
- We use `ui_test` to test compiler errors for our custom macros.
- There are four crates related to compile fail tests
- `bevy_ecs_compile_fail_tests`, `bevy_macros_compile_fail_tests`, and
`bevy_reflect_compile_fail_tests`, which actually test the macros.
-
[`bevy_compile_test_utils`](64c1c65783/crates/bevy_compile_test_utils),
which provides helpers and common patterns for these tests.
- All of these crates reside within the `crates` directory.
- This can be confusing, especially for newcomers. All of the other
folders in `crates` are actual published libraries, except for these 4.
## Solution
- Move all compile fail tests to a `compile_fail` folder under their
corresponding crate.
- E.g. `crates/bevy_ecs_compile_fail_tests` would be moved to
`crates/bevy_ecs/compile_fail`.
- Move `bevy_compile_test_utils` to `tools/compile_fail_utils`.
There are a few benefits to this approach:
1. An internal testing detail is less intrusive (and confusing) for
those who just want to browse the public Bevy interface.
2. Follows a pre-existing approach of organizing related crates inside a
larger crate's folder.
- See `bevy_gizmos/macros` for an example.
4. Makes consistent the terms `compile_test`, `compile_fail`, and
`compile_fail_test` in code. It's all just `compile_fail` now, because
we are specifically testing the error messages on compiler failures.
- To be clear it can still be referred to by these terms in comments and
speech, just the names of the crates and the CI command are now
consistent.
## Testing
Run the compile fail CI command:
```shell
cargo run -p ci -- compile-fail
```
If it still passes, then my refactor was successful.
# Objective
- Many of the items in the `ci` tool use `pub(crate)`, which is
functionally equivalent to `pub` when the crate is not a library.
- A few items are missing documentation.
## Solution
- Make all `pub(crate)` items just `pub`.
- `pub` is easier to type and less obscure, and there's not harm from
this change.
- Add / modify documentation on `CI`, `Prepare`, and `PreparedCommand`.
# Objective
- Currently all `ci` commands are in the `subcommands` module. This is
problematic when you want to implement actually subcommands (such as
`cargo r -p ci -- doc check`).
- All command modules include the `_command` suffix, which is redundant.
## Solution
- Move `commands` modules into root crate folder.
- Merge contents of `commands/mod.rs` into `main.rs`.
- Move `commands::subcommands` module into `commands` module.
- Remove the `_command` suffix from all `commands::subcommands` modules.
# Objective
The CI tool currently parses input manually. This has worked fine, but
makes it just a bit more difficult to maintain and extend. Additionally,
it provides no usage help for devs wanting to run the tool locally.
It would be better if parsing was handled by a dedicated CLI library
like [`clap`](https://github.com/clap-rs/clap) or
[`argh`](https://github.com/google/argh).
## Solution
Use `argh` to parse command line input for CI.
`argh` was chosen over `clap` and other tools due to being more
lightweight and already existing in our dependency tree.
Using `argh`, the usage notes are generated automatically:
```
$ cargo run -p ci --quiet -- --help
Usage: ci [--keep-going] [<command>] [<args>]
The CI command line tool for Bevy.
Options:
--keep-going continue running commands even if one fails
--help display usage information
Commands:
lints Alias for running the `format` and `clippy` subcommands.
doc Alias for running the `doc-test` and `doc-check`
subcommands.
compile Alias for running the `compile-fail`, `bench-check`,
`example-check`, `compile-check`, and `test-check`
subcommands.
format Check code formatting.
clippy Check for clippy warnings and errors.
test Runs all tests (except for doc tests).
test-check Checks that all tests compile.
doc-check Checks that all docs compile.
doc-test Runs all doc tests.
compile-check Checks that the project compiles.
cfg-check Checks that the project compiles using the nightly compiler
with cfg checks enabled.
compile-fail Runs the compile-fail tests.
bench-check Checks that the benches compile.
example-check Checks that the examples compile.
```
This PR makes each subcommand more modular, allowing them to be called
from other subcommands. This also makes it much easier to extract them
out of `main.rs` and into their own dedicated modules.
Additionally, this PR improves failure output:
```
$ cargo run -p ci -- lints
...
One or more CI commands failed:
format: Please run 'cargo fmt --all' to format your code.
```
Including when run with the `--keep-going` flag:
```
$ cargo run -p ci -- --keep-going lints
...
One or more CI commands failed:
- format: Please run 'cargo fmt --all' to format your code.
- clippy: Please fix clippy errors in output above.
```
### Future Work
There are a lot of other things we could possibly clean up. I chose to
try and keep the API surface as unchanged as I could (for this PR at
least).
For example, now that each subcommand is an actual command, we can
specify custom arguments for each.
The `format` subcommand could include a `--check` (making the default
fun `cargo fmt` as normal). Or the `compile-fail` subcommand could
include `--ecs`, `--reflect`, and `--macros` flags for specifying which
set of compile fail tests to run.
The `--keep-going` flag could be split so that it doesn't do double-duty
where it also enables `--no-fail-fast` for certain commands. Or at least
make it more explicit via renaming or using alternative flags.
---
## Changelog
- Improved the CI CLI tool
- Now includes usage info with the `--help` option!
- [Internal] Cleaned up and refactored the `tools/ci` crate using the
`argh` crate
## Migration Guide
The CI tool no longer supports running multiple subcommands in a single
call. Users who are currently doing so will need to split them across
multiple commands:
```bash
# BEFORE
cargo run -p ci -- lints doc compile
# AFTER
cargo run -p ci -- lints && cargo run -p ci -- doc && cargo run -p ci -- compile
# or
cargo run -p ci -- lints; cargo run -p ci -- doc; cargo run -p ci -- compile
# or
cargo run -p ci -- lints
cargo run -p ci -- doc
cargo run -p ci -- compile
```
