Deprecate dynamic plugins (#13080)
# Objective

- The current implementation for dynamic plugins is unsound. Please see
#11969 for background and justification.
- Closes #11969 and closes #13073.

## Solution

- Deprecate all dynamic plugin items for Bevy 0.14, with plans to remove
them for Bevy 0.15.

## Discussion

One thing I want to make clear is that I'm not opposed to dynamic
plugins _in general_. I think they can be handy, especially for DLC and
modding, but I think the current system is the wrong approach. It's too
much of a footgun for the meager benefit is provides.

---

## Changelog

- Deprecated the current dynamic plugin system.
- Dynamic plugins will be removed in Bevy 0.15. For now you can continue
using them by marking your code with `#[allow(deprecated)]`.

## Migration Guide

If possible, remove all usage of dynamic plugins.

```rust
// Old
#[derive(DynamicPlugin)]
pub struct MyPlugin;

App::new()
    .load_plugin("path/to/plugin")
    .run();

// New
pub struct MyPlugin;

App::new()
    .add_plugins(MyPlugin)
    .run();
```

If you are unable to do that, you may temporarily silence the
deprecation warnings.

```rust
#[allow(deprecated)]
```

Please note that the current dynamic plugin system will be removed by
the next major Bevy release, so you will have to migrate eventually. You

Move compile fail tests (#13196)
# 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.

Add README.md to all crates (#13184)
# Objective

- `README.md` is a common file that usually gives an overview of the
folder it is in.
- When on <https://crates.io>, `README.md` is rendered as the main
description.
- Many crates in this repository are lacking `README.md` files, which
makes it more difficult to understand their purpose.

<img width="1552" alt="image"
src="https://github.com/bevyengine/bevy/assets/59022059/78ebf91d-b0c4-4b18-9874-365d6310640f">

- There are also a few inconsistencies with `README.md` files that this
PR and its follow-ups intend to fix.

## Solution

- Create a `README.md` file for all crates that do not have one.
- This file only contains the title of the crate (underscores removed,
proper capitalization, acronyms expanded) and the <https://shields.io>
badges.
- Remove the `readme` field in `Cargo.toml` for `bevy` and
`bevy_reflect`.
- This field is redundant because [Cargo automatically detects
`README.md`
files](https://doc.rust-lang.org/cargo/reference/manifest.html#the-readme-field).
The field is only there if you name it something else, like `INFO.md`.
- Fix capitalization of `bevy_utils`'s `README.md`.
- It was originally `Readme.md`, which is inconsistent with the rest of
the project.
- I created two commits renaming it to `README.md`, because Git appears
to be case-insensitive.
- Expand acronyms in title of `bevy_ptr` and `bevy_utils`.
- In the commit where I created all the new `README.md` files, I
preferred using expanded acronyms in the titles. (E.g. "Bevy Developer
Tools" instead of "Bevy Dev Tools".)
- This commit changes the title of existing `README.md` files to follow
the same scheme.
- I do not feel strongly about this change, please comment if you
disagree and I can revert it.
- Add <https://shields.io> badges to `bevy_time` and `bevy_transform`,
which are the only crates currently lacking them.

---

## Changelog

- Added `README.md` files to all crates missing it.

Forbid unsafe in most crates in the engine (#12684)
# Objective
Resolves #3824. `unsafe` code should be the exception, not the norm in
Rust. It's obviously needed for various use cases as it's interfacing
with platforms and essentially running the borrow checker at runtime in
the ECS, but the touted benefits of Bevy is that we are able to heavily
leverage Rust's safety, and we should be holding ourselves accountable
to that by minimizing our unsafe footprint.

## Solution
Deny `unsafe_code` workspace wide. Add explicit exceptions for the
following crates, and forbid it in almost all of the others.

* bevy_ecs - Obvious given how much unsafe is needed to achieve
performant results
* bevy_ptr - Works with raw pointers, even more low level than bevy_ecs.
 * bevy_render - due to needing to integrate with wgpu
 * bevy_window - due to needing to integrate with raw_window_handle
* bevy_utils - Several unsafe utilities used by bevy_ecs. Ideally moved
into bevy_ecs instead of made publicly usable.
 * bevy_reflect - Required for the unsafe type casting it's doing.
 * bevy_transform - for the parallel transform propagation
 * bevy_gizmos  - For the SystemParam impls it has.
* bevy_assets - To support reflection. Might not be required, not 100%
sure yet.
* bevy_mikktspace - due to being a conversion from a C library. Pending
safe rewrite.
* bevy_dynamic_plugin - Inherently unsafe due to the dynamic loading
nature.

Several uses of unsafe were rewritten, as they did not need to be using
them:

* bevy_text - a case of `Option::unchecked` could be rewritten as a
normal for loop and match instead of an iterator.
* bevy_color - the Pod/Zeroable implementations were replaceable with
bytemuck's derive macros.

Set the logo and favicon for all of Bevy's published crates (#12696)
# Objective
Currently the built docs only shows the logo and favicon for the top
level `bevy` crate. This makes views like
https://docs.rs/bevy_ecs/latest/bevy_ecs/ look potentially unrelated to
the project at first glance.

## Solution
Reproduce the docs attributes for every crate that Bevy publishes.

Ideally this would be done with some workspace level Cargo.toml control,
but AFAICT, such support does not exist.

Make feature(doc_auto_cfg) work (#12642)
# Objective

- In #12366 `![cfg_attr(docsrs, feature(doc_auto_cfg))] `was added. But
to apply it it needs `--cfg=docsrs` in rustdoc-args.


## Solution

- Apply `--cfg=docsrs` to all crates and CI.

I also added `[package.metadata.docs.rs]` to all crates to avoid adding
code behind a feature and forget adding the metadata.

Inverse missing_docs logic (#11676)
# Objective

Currently the `missing_docs` lint is allowed-by-default and enabled at
crate level when their documentations is complete (see #3492).
This PR proposes to inverse this logic by making `missing_docs`
warn-by-default and mark crates with imcomplete docs allowed.

## Solution

Makes `missing_docs` warn at workspace level and allowed at crate level
when the docs is imcomplete.

Replace all labels with interned labels (#7762)
# Objective

First of all, this PR took heavy inspiration from #7760 and #5715. It
intends to also fix #5569, but with a slightly different approach.


This also fixes #9335 by reexporting `DynEq`.

## Solution

The advantage of this API is that we can intern a value without
allocating for zero-sized-types and for enum variants that have no
fields. This PR does this automatically in the `SystemSet` and
`ScheduleLabel` derive macros for unit structs and fieldless enum
variants. So this should cover many internal and external use cases of
`SystemSet` and `ScheduleLabel`. In these optimal use cases, no memory
will be allocated.

- The interning returns a `Interned<dyn SystemSet>`, which is just a
wrapper around a `&'static dyn SystemSet`.
- `Hash` and `Eq` are implemented in terms of the pointer value of the
reference, similar to my first approach of anonymous system sets in
#7676.
- Therefore, `Interned<T>` does not implement `Borrow<T>`, only `Deref`.
- The debug output of `Interned<T>` is the same as the interned value.

Edit: 
- `AppLabel` is now also interned and the old
`derive_label`/`define_label` macros were replaced with the new
interning implementation.
- Anonymous set ids are reused for different `Schedule`s, reducing the
amount of leaked memory.

### Pros
- `InternedSystemSet` and `InternedScheduleLabel` behave very similar to
the current `BoxedSystemSet` and `BoxedScheduleLabel`, but can be copied
without an allocation.
- Many use cases don't allocate at all.
- Very fast lookups and comparisons when using `InternedSystemSet` and
`InternedScheduleLabel`.
- The `intern` module might be usable in other areas.
- `Interned{ScheduleLabel, SystemSet, AppLabel}` does implement
`{ScheduleLabel, SystemSet, AppLabel}`, increasing ergonomics.

### Cons
- Implementors of `SystemSet` and `ScheduleLabel` still need to
implement `Hash` and `Eq` (and `Clone`) for it to work.

## Changelog

### Added

- Added `intern` module to `bevy_utils`.
- Added reexports of `DynEq` to `bevy_ecs` and `bevy_app`.

### Changed

- Replaced `BoxedSystemSet` and `BoxedScheduleLabel` with
`InternedSystemSet` and `InternedScheduleLabel`.
- Replaced `impl AsRef<dyn ScheduleLabel>` with `impl ScheduleLabel`.
- Replaced `AppLabelId` with `InternedAppLabel`.
- Changed `AppLabel` to use `Debug` for error messages.
- Changed `AppLabel` to use interning.
- Changed `define_label`/`derive_label` to use interning. 
- Replaced `define_boxed_label`/`derive_boxed_label` with
`define_label`/`derive_label`.
- Changed anonymous set ids to be only unique inside a schedule, not
globally.
- Made interned label types implement their label trait. 

### Removed

- Removed `define_boxed_label` and `derive_boxed_label`. 

## Migration guide

- Replace `BoxedScheduleLabel` and `Box<dyn ScheduleLabel>` with
`InternedScheduleLabel` or `Interned<dyn ScheduleLabel>`.
- Replace `BoxedSystemSet` and `Box<dyn SystemSet>` with
`InternedSystemSet` or `Interned<dyn SystemSet>`.
- Replace `AppLabelId` with `InternedAppLabel` or `Interned<dyn
AppLabel>`.
- Types manually implementing `ScheduleLabel`, `AppLabel` or `SystemSet`
need to implement:
  - `dyn_hash` directly instead of implementing `DynHash`
  - `as_dyn_eq`
- Pass labels to `World::try_schedule_scope`, `World::schedule_scope`,
`World::try_run_schedule`. `World::run_schedule`, `Schedules::remove`,
`Schedules::remove_entry`, `Schedules::contains`, `Schedules::get` and
`Schedules::get_mut` by value instead of by reference.

bevy_derive: Fix #[deref] breaking other attributes (#9551)
# Objective

Fixes #9550

## Solution

Removes a check that asserts that _all_ attribute metas are path-only,
rather than just the `#[deref]` attribute itself.

---

## Changelog

- Fixes an issue where deriving `Deref` with `#[deref]` on a field
causes other attributes to sometimes result in a compile error

bevy_derive: Add #[deref] attribute (#8552)
# Objective

Bevy code tends to make heavy use of the [newtype](
https://doc.rust-lang.org/rust-by-example/generics/new_types.html)
pattern, which is why we have a dedicated derive for
[`Deref`](https://doc.rust-lang.org/std/ops/trait.Deref.html) and
[`DerefMut`](https://doc.rust-lang.org/std/ops/trait.DerefMut.html).
This derive works for any struct with a single field:

```rust
#[derive(Component, Deref, DerefMut)]
struct MyNewtype(usize);
```

One reason for the single-field limitation is to prevent confusion and
footguns related that would arise from allowing multi-field structs:

<table align="center">
<tr>
<th colspan="2">
Similar structs, different derefs
</th>
</tr>
<tr>
<td>

```rust
#[derive(Deref, DerefMut)]
struct MyStruct {
  foo: usize, // <- Derefs usize
  bar: String,
}
```

</td>
<td>

```rust
#[derive(Deref, DerefMut)]
struct MyStruct {
  bar: String, // <- Derefs String
  foo: usize,
}
```

</td>
</tr>
<tr>
<th colspan="2">
Why `.1`?
</th>
</tr>
<tr>
<td colspan="2">

```rust
#[derive(Deref, DerefMut)]
struct MyStruct(Vec<usize>, Vec<f32>);

let mut foo = MyStruct(vec![123], vec![1.23]);

// Why can we skip the `.0` here?
foo.push(456);
// But not here?
foo.1.push(4.56);
```

</td>
</tr>
</table>

However, there are certainly cases where it's useful to allow for
structs with multiple fields. Such as for structs with one "real" field
and one `PhantomData` to allow for generics:

```rust
#[derive(Deref, DerefMut)]
struct MyStruct<T>(
  // We want use this field for the `Deref`/`DerefMut` impls
  String,
  // But we need this field so that we can make this struct generic
  PhantomData<T>
);

// ERROR: Deref can only be derived for structs with a single field
// ERROR: DerefMut can only be derived for structs with a single field
```

Additionally, the possible confusion and footguns are mainly an issue
for newer Rust/Bevy users. Those familiar with `Deref` and `DerefMut`
understand what adding the derive really means and can anticipate its
behavior.

## Solution

Allow users to opt into multi-field `Deref`/`DerefMut` derives using a
`#[deref]` attribute:

```rust
#[derive(Deref, DerefMut)]
struct MyStruct<T>(
  // Use this field for the `Deref`/`DerefMut` impls
  #[deref] String,
  // We can freely include any other field without a compile error
  PhantomData<T>
);
```

This prevents the footgun pointed out in the first issue described in
the previous section, but it still leaves the possible confusion
surrounding `.0`-vs-`.#`. However, the idea is that by making this
behavior explicit with an attribute, users will be more aware of it and
can adapt appropriately.

## Changelog

- Added `#[deref]` attribute to `Deref` and `DerefMut` derives

Suppress the clippy::type_complexity lint (#8313)
# Objective

The clippy lint `type_complexity` is known not to play well with bevy.
It frequently triggers when writing complex queries, and taking the
lint's advice of using a type alias almost always just obfuscates the
code with no benefit. Because of this, this lint is currently ignored in
CI, but unfortunately it still shows up when viewing bevy code in an
IDE.

As someone who's made a fair amount of pull requests to this repo, I
will say that this issue has been a consistent thorn in my side. Since
bevy code is filled with spurious, ignorable warnings, it can be very
difficult to spot the *real* warnings that must be fixed -- most of the
time I just ignore all warnings, only to later find out that one of them
was real after I'm done when CI runs.

## Solution

Suppress this lint in all bevy crates. This was previously attempted in
#7050, but the review process ended up making it more complicated than
it needs to be and landed on a subpar solution.

The discussion in https://github.com/rust-lang/rust-clippy/pull/10571
explores some better long-term solutions to this problem. Since there is
no timeline on when these solutions may land, we should resolve this
issue in the meantime by locally suppressing these lints.

### Unresolved issues

Currently, these lints are not suppressed in our examples, since that
would require suppressing the lint in every single source file. They are
still ignored in CI.

44e9cd4bfc Add attribute to ignore fields of derived labels (#5366)
# Objective

Fixes #5362 

## Solution

Add the attribute `#[label(ignore_fields)]` for `*Label` types.

```rust
#[derive(SystemLabel)]
pub enum MyLabel {
    One,

    // Previously this was not allowed since labels cannot contain data.
    #[system_label(ignore_fields)]
    Two(PhantomData<usize>),
}
```

## Notes

This label makes it possible for equality to behave differently depending on whether or not you are treating the type as a label. For example:

```rust
#[derive(SystemLabel, PartialEq, Eq)]
#[system_label(ignore_fields)]
pub struct Foo(usize);
```

If you compare it as a label, it will ignore the wrapped fields as the user requested. But if you compare it as a `Foo`, the derive will incorrectly compare the inner fields. I see a few solutions

1. Do nothing. This is technically intended behavior, but I think we should do our best to prevent footguns.
2. Generate impls of `PartialEq` and `Eq` along with the `#[derive(Label)]` macros. This is a breaking change as it requires all users to remove these derives from their types.
3. Only allow `PhantomData` to be used with `ignore_fields` -- seems needlessly prescriptive.

---

## Changelog

* Added the `ignore_fields` attribute to the derive macros for `*Label` types.
* Added an example showing off different forms of the derive macro.

## Migration Guide

> This section is optional. If there are no breaking changes, you can delete this section.

- If this PR is a breaking change (relative to the last release of Bevy), describe how a user might need to migrate their code to support these changes
- Simply adding new functionality is not a breaking change.
- Fixing behavior that was definitely a bug, rather than a questionable design choice is not a breaking change.

d4e4a92982 android - fix issues other than the rendering (#5130)
# Objective

- Make Bevy work on android

## Solution

- Update android metadata and add a few more
- Set the target sdk to 31 as it will soon (in august) be the minimum sdk level for play store
- Remove the custom code to create an activity and use ndk-glue macro instead
- Delay window creation event on android
- Set the example with compatibility settings for wgpu. Those are needed for Bevy to work on my 2019 android tablet
- Add a few details on how to debug in case of failures
- Fix running the example on emulator. This was failing because of the name of the example

Bevy still doesn't work on android with this, audio features need to be disabled because of an ndk-glue version mismatch: rodio depends on 0.6.2, winit on 0.5.2. You can test with:
```
cargo apk run --release --example android_example --no-default-features --features "bevy_winit,render"
```

ddce22b614 Decouple some dependencies (#3886)
# Objective

Reduce from scratch build time.

## Solution

Reduce the size of the critical path by removing dependencies between crates where not necessary. For `cargo check --no-default-features` this reduced build time from ~51s to ~45s. For some commits I am not completely sure if the tradeoff between build time reduction and convenience caused by the commit is acceptable. If not, I can drop them.

f16768d868 bevy_derive: Add derives for Deref and DerefMut (#4328)
# Objective

A common pattern in Rust is the [newtype](https://doc.rust-lang.org/rust-by-example/generics/new_types.html). This is an especially useful pattern in Bevy as it allows us to give common/foreign types different semantics (such as allowing it to implement `Component` or `FromWorld`) or to simply treat them as a "new type" (clever). For example, it allows us to wrap a common `Vec<String>` and do things like:

```rust
#[derive(Component)]
struct Items(Vec<String>);

fn give_sword(query: Query<&mut Items>) { 
  query.single_mut().0.push(String::from("Flaming Poisoning Raging Sword of Doom"));
}
```

> We could then define another struct that wraps `Vec<String>` without anything clashing in the query.

However, one of the worst parts of this pattern is the ugly `.0` we have to write in order to access the type we actually care about. This is why people often implement `Deref` and `DerefMut` in order to get around this.

Since it's such a common pattern, especially for Bevy, it makes sense to add a derive macro to automatically add those implementations.


## Solution

Added a derive macro for `Deref` and another for `DerefMut` (both exported into the prelude). This works on all structs (including tuple structs) as long as they only contain a single field:

```rust
#[derive(Deref)]
struct Foo(String);

#[derive(Deref, DerefMut)]
struct Bar {
  name: String,
}
```

This allows us to then remove that pesky `.0`:

```rust
#[derive(Component, Deref, DerefMut)]
struct Items(Vec<String>);

fn give_sword(query: Query<&mut Items>) { 
  query.single_mut().push(String::from("Flaming Poisoning Raging Sword of Doom"));
}
```

### Alternatives

There are other alternatives to this such as by using the [`derive_more`](https://crates.io/crates/derive_more) crate. However, it doesn't seem like we need an entire crate just yet since we only need `Deref` and `DerefMut` (for now).

### Considerations

One thing to consider is that the Rust std library recommends _not_ using `Deref` and `DerefMut` for things like this: "`Deref` should only be implemented for smart pointers to avoid confusion" ([reference](https://doc.rust-lang.org/std/ops/trait.Deref.html)). Personally, I believe it makes sense to use it in the way described above, but others may disagree.

## Changelog

- Add `Deref` derive macro (exported to prelude)
- Add `DerefMut` derive macro (exported to prelude)
- Updated most newtypes in examples to use one or both derives

7ce3ae43e3 Bump Bevy to 0.7.0-dev (#4230)
# Objective

- The [dev docs](https://dev-docs.bevyengine.org/bevy/index.html#) show version 0.6.0, which is actively misleading.

[Image of the problem](https://cdn.discordapp.com/attachments/695741366520512563/953513612943704114/Screenshot_20220316-154100_Firefox-01.jpeg)

Noticed by @ickk, fix proposed by @mockersf.

## Solution

- Bump the version across all Bevy crates to 0.7.0 dev.
- Set a reminder in the Release Checklist to remember to do this each release.

d8974e7c3d small and mostly pointless refactoring (#2934)
What is says on the tin.

This has got more to do with making `clippy` slightly more *quiet* than it does with changing anything that might greatly impact readability or performance.

that said, deriving `Default` for a couple of structs is a nice easy win

8e1f660e1d Don't panic in macro shape validation (#3647)
# Objective
Emitting compile errors produces cleaner messages than panicking in a proc-macro.

## Solution
- Replace match-with-panic code with call to new `bevy_macro_utils::get_named_struct_fields` function
- Replace one use of match-with-panic for enums with inline match

_Aside:_ I'm also the maintainer of [`darling`](https://docs.rs/darling), a crate which provides a serde-like API for parsing macro inputs. I avoided using it here because it seemed like overkill, but if there are plans to add lots more attributes/macros then that might be a good way of offloading macro error handling.

dc8fefe27f Remove Bytes, FromBytes, Labels, EntityLabels. Document rest of bevy_core and enable warning on missing docs. (#3521)
This PR is part of the issue #3492.

# Objective

 - Clean up dead code in `bevy_core`.
 - Add and update the `bevy_core` documentation to achieve a 100% documentation coverage.
 - Add the #![warn(missing_docs)] lint to keep the documentation coverage for the future.

# Solution

 - Remove unused `Bytes`, `FromBytes`, `Labels`, and `EntityLabels` types and associated systems.
 - Made several types private that really only have use as internal types, mostly pertaining to fixed timestep execution.
 - Add and update the bevy_core documentation.
 - Add the #![warn(missing_docs)] lint.

# Open Questions

Should more of the internal states of `FixedTimestep` be public? Seems mostly to be an implementation detail unless someone really needs that fixed timestep state.

ffde86efa0 Update to edition 2021 on master (#3028)
Objective
During work on #3009 I've found that not all jobs use actions-rs, and therefore, an previous version of Rust is used for them. So while compilation and other stuff can pass, checking markup and Android build may fail with compilation errors.

Solution
This PR adds `action-rs` for any job running cargo, and updates the edition to 2021.
