321d998615 Add convenience methods for checking a set of inputs (#2760)
# Objective

Make it easier to check if some set of inputs matches a key, such as if you want to allow all of space or up or w for jumping.

Currently, this requires:
```rust
if keyboard.pressed(KeyCode::Space)
            || keyboard.pressed(KeyCode::Up)
            || keyboard.pressed(KeyCode::W) {
    // ...
```

## Solution

Add an implementation of the helper methods, which very simply iterate through the items, used as:
```rust
if keyboard.any_pressed([KeyCode::Space, KeyCode::Up, KeyCode::W]) {
```

af20cad830 Add error messages for the spooky insertions (#2581)
# Objective

Sometimes, the unwraps in `entity_mut` could fail here, if the entity was despawned *before* this command was applied.

The simplest case involves two command buffers:
```rust
use bevy::prelude::*;
fn b(mut commands1: Commands, mut commands2: Commands) {
    let id = commands2.spawn().insert_bundle(()).id();
    commands1.entity(id).despawn();
}
fn main() {
    App::build().add_system(b.system()).run();
}
```

However, a more complicated version arises in the case of ambiguity:

```rust
use std::time::Duration;

use bevy::{app::ScheduleRunnerPlugin, prelude::*};
use rand::Rng;

fn cleanup(mut e: ResMut<Option<Entity>>) {
    *e = None;
}

fn sleep_randomly() {
    let mut rng = rand::thread_rng();
    std:🧵:sleep(Duration::from_millis(rng.gen_range(0..50)));
}

fn spawn(mut commands: Commands, mut e: ResMut<Option<Entity>>) {
    *e = Some(commands.spawn().insert_bundle(()).id());
}

fn despawn(mut commands: Commands, e: Res<Option<Entity>>) {
    let mut rng = rand::thread_rng();
    std:🧵:sleep(Duration::from_millis(rng.gen_range(0..50)));
    if let Some(e) = *e {
        commands.entity(e).despawn();
    }
}

fn main() {
    App::build()
        .add_system(cleanup.system().label("cleanup"))
        .add_system(sleep_randomly.system().label("before_despawn"))
        .add_system(despawn.system().after("cleanup").after("before_despawn"))
        .add_system(sleep_randomly.system().label("before_spawn"))
        .add_system(spawn.system().after("cleanup").after("before_spawn"))
        .insert_resource(None::<Entity>)
        .add_plugin(ScheduleRunnerPlugin::default())
        .run();
}
```

In the cases where this example crashes, it's because `despawn` was ordered before `spawn` in the topological ordering of systems (which determines when buffers are applied). However, `despawn` actually ran *after* `spawn`, because these systems are ambiguous, so the jiggles in the sleeping time triggered a case where this works.

## Solution

- Give a better error message

dea292d199 Derive thiserror::Error for HexColorError (#2740)
# Objective

- Make it easy to use HexColorError with `thiserror`, i.e. converting it into other error types.

Makes this possible:

```rust
#[derive(Debug, thiserror::Error)]
pub enum LdtkError {
    #[error("An error occured while deserializing")]
    Json(#[from] serde_json::Error),
    #[error("An error occured while parsing a color")]
    HexColor(#[from] bevy::render::color::HexColorError),
}
```

## Solution

- Derive thiserror::Error the same way we do elsewhere (see query.rs for instance)

d4a552a31a Add aarch64-apple-darwin to the config_fast_builds for Apple Silicon (#2739)
# Objective

M1 Macs / Apple Silicon / simply aarch64 needs to be specified for it to compile with zld, so users might be surprised to find that they aren't getting the benefits and see the fast compiles they might be seeing on other platforms.

## Solution

- Add it? :)

b47217bfab Spawn specific entities: spawn or insert operations, refactor spawn internals, world clearing (#2673)
This upstreams the code changes used by the new renderer to enable cross-app Entity reuse:

* Spawning at specific entities
* get_or_spawn: spawns an entity if it doesn't already exist and returns an EntityMut
* insert_or_spawn_batch: the batched equivalent to `world.get_or_spawn(entity).insert_bundle(bundle)`
* Clearing entities and storages
* Allocating Entities with "invalid" archetypes. These entities cannot be queried / are treated as "non existent". They serve as "reserved" entities that won't show up when calling `spawn()`. They must be "specifically spawned at" using apis like `get_or_spawn(entity)`.

In combination, these changes enable the "render world" to clear entities / storages each frame and reserve all "app world entities". These can then be spawned during the "render extract step".

This refactors "spawn" and "insert" code in a way that I think is a massive improvement to legibility and re-usability. It also yields marginal performance wins by reducing some duplicate lookups (less than a percentage point improvement on insertion benchmarks). There is also some potential for future unsafe reduction (by making BatchSpawner and BatchInserter generic). But for now I want to cut down generic usage to a minimum to encourage smaller binaries and faster compiles.

This is currently a draft because it needs more tests (although this code has already had some real-world testing on my custom-shaders branch). 

I also fixed the benchmarks (which currently don't compile!) / added new ones to illustrate batching wins.

After these changes, Bevy ECS is basically ready to accommodate the new renderer. I think the biggest missing piece at this point is "sub apps".

481fa3c7a0 derive Debug, Clone for FixedState (StableAHash) (#2694)
This matches `ahash::RandomState`, which provides both `Debug` and `Clone`.

Notably, implementing `Clone` allows the `StableHashMap`/`Set` to also implement `Clone`.

# Objective

- Allow `bevy_utils::StableHashMap` to be cloned.

## Solution

- Derive `Clone` for `bevy_utils::FixedState`.
- Also derive `Debug`, since we're touching it anyway, and this aligns `FixedState` with `ahash::RandomState`.

98a08cf495 feat: remove_component for ReflectComponent (#2682)
# Objective

While implementing a plugin for my rollback networking library, I needed to load/save parts of the world. For this, I made a WorldSnapshot that works quite like the current DynamicScene. Using a TypeRegistry to register component types I want to save/load and then using ReflectComponents methods to add or apply components of the given types. 

However, I noticed there is no method to remove components from entities through the ReflectComponent.

## Solution

I added a `remove_component` field to the `ReflectComponent` struct, as well as a `pub fn remove_component(&self, world: &mut World, entity: Entity)` to call that function in `remove_component`. This follows exactly the same pattern all other methods/fields in this struct look like.

This is an example how it could be used (at least how I would use it):

9d453530fa System Param Lifetime Split (#2605)
# Objective

Enable using exact World lifetimes during read-only access . This is motivated by the new renderer's need to allow read-only world-only queries to outlive the query itself (but still be constrained by the world lifetime).

For example:
115b170d1f/pipelined/bevy_pbr2/src/render/mod.rs (L774)

## Solution

Split out SystemParam state and world lifetimes and pipe those lifetimes up to read-only Query ops (and add into_inner for Res). According to every safety test I've run so far (except one), this is safe (see the temporary safety test commit). Note that changing the mutable variants to the new lifetimes would allow aliased mutable pointers (try doing that to see how it affects the temporary safety tests).

The new state lifetime on SystemParam does make `#[derive(SystemParam)]` more cumbersome (the current impl requires PhantomData if you don't use both lifetimes). We can make this better by detecting whether or not a lifetime is used in the derive and adjusting accordingly, but that should probably be done in its own pr.  

## Why is this a draft?

The new lifetimes break QuerySet safety in one very specific case (see the query_set system in system_safety_test). We need to solve this before we can use the lifetimes given.

This is due to the fact that QuerySet is just a wrapper over Query, which now relies on world lifetimes instead of `&self` lifetimes to prevent aliasing (but in systems, each Query has its own implied lifetime, not a centralized world lifetime).  I believe the fix is to rewrite QuerySet to have its own World lifetime (and own the internal reference). This will complicate the impl a bit, but I think it is doable. I'm curious if anyone else has better ideas.

Personally, I think these new lifetimes need to happen. We've gotta have a way to directly tie read-only World queries to the World lifetime. The new renderer is the first place this has come up, but I doubt it will be the last. Worst case scenario we can come up with a second `WorldLifetimeQuery<Q, F = ()>` parameter to enable these read-only scenarios, but I'd rather not add another type to the type zoo.

d59fc076e8 Comprehensive CONTRIBUTING.md (#2040)
[**RENDERED**](https://github.com/alice-i-cecile/bevy/blob/better-contributing/CONTRIBUTING.md)

Improves #910. As discussed in #1309, we'll need to synchronize content between this and the Bevy website in some way (and clean up the .github file perhaps?).

I think doing it as a root-directory file is nicer for discovery, but that's a conversation I'm interested in having.

This document is intended to be helpful to beginners to open source and Bevy, and captures what I've learned about our informal practices and values.

Reviewers: I'm particularly interested in:
- opinions on the items **What we're trying to build**, where I discuss some of the project's high-level values and goals
- more relevant details on the `bevy` subcrates for **Getting oriented**
- useful tricks and best practices that I missed
- better guidance on how to contribute to the Bevy book from @cart <3

96f0e02728 Implement Clone for Fetches (#2641)
# Objective

This:

```rust
use bevy::prelude::*;

fn main() {
    App::new()
    .add_system(test)
    .run();
}

fn test(entities: Query<Entity>) {
    let mut combinations = entities.iter_combinations_mut();
    while let Some([e1, e2]) = combinations.fetch_next() {    
        dbg!(e1);
    }
}
```

fails with the message "the trait bound `bevy::ecs::query::EntityFetch: std::clone::Clone` is not satisfied". 


## Solution

It works after adding the naive clone implementation to EntityFetch. I'm not super familiar with ECS internals, so I'd appreciate input on this.

0c91317102 Change definition of ScheduleRunnerPlugin (#2606)
# Objective

- Allow `ScheduleRunnerPlugin` to be instantiated without curly braces. Other plugins in the library already use the semicolon syntax.
- Currently, you have to do the following:
```rust
App::build()
    .add_plugin(bevy::core::CorePlugin)
    .add_plugin(bevy::app::ScheduleRunnerPlugin {})
```
- With the proposed change you can do this:
```rust
App::build()
    .add_plugin(bevy::core::CorePlugin)
    .add_plugin(bevy::app::ScheduleRunnerPlugin)
```

## Solution

- Change the `ScheduleRunnerPlugin` definition to use a semicolon instead of curly braces.

43d99bb583 Remove bevy_dynamic_plugin as a default (#2578)
It doesn't compile on wasm, and it's full of footguns

# Objective

- If bevy is used with default features on wasm, there's more of a chance it will compile
- Note that I haven't done a full audit - it's possible that there are other problematic crates

## Solution

- `bevy_dynamic_plugin` is no longer a default plugin
- I've also done an accidental drive by reformatting of the root `Cargo.toml`, as I have [Even Better Toml](https://github.com/tamasfe/taplo) installed.
- (Please, rustfmt do this for us)

54ff7aaa1e Bump notify to 5.0.0-pre.11 (#2564)
# Objective

notify 5.0.0-pre.11 breaks the interface again, but apparently in a way that's similar to how it used to be

## Solution

Bump `bevy_asset` dependency on notify to `5.0.0-pre.11` and fix the errors that crop up.

It looks like `pre.11` was mentioned in #2528 by @mockersf but there's no mention of why `pre.10` was chosen ultimately.

86cc70b902 Refactor ECS to reduce the dependency on a 1-to-1 mapping between components and real rust types (#2490)
# Objective

There is currently a 1-to-1 mapping between components and real rust types. This means that it is impossible for multiple components to be represented by the same rust type or for a component to not have a rust type at all. This means that component types can't be defined in languages other than rust like necessary for scripting or sandboxed (wasm?) plugins.

## Solution

Refactor `ComponentDescriptor` and `Bundle` to remove `TypeInfo`. `Bundle` now uses `ComponentId` instead. `ComponentDescriptor` is now always created from a rust type instead of through the `TypeInfo` indirection. A future PR may make it possible to construct a `ComponentDescriptor` from it's fields without a rust type being involved.

# Objective

- Remove all the `.system()` possible.
- Check for remaining missing cases.

## Solution

- Remove all `.system()`, fix compile errors
- 32 calls to `.system()` remains, mostly internals, the few others should be removed after #2446

234b2efa71 Inline world get (#2520)
# Objective

While looking at the code of `World`, I noticed two basic functions (`get` and `get_mut`) that are probably called a lot and with simple code that are not `inline`

## Solution

- Add benchmark to check impact
- Add `#[inline]`

I didn't add benchmarks for the mutable path but I don't see how it could hurt to make it inline too...

6d6bc2a8b4 Merge AppBuilder into App (#2531)
This is extracted out of eb8f973646476b4a4926ba644a77e2b3a5772159 and includes some additional changes to remove all references to AppBuilder and fix examples that still used App::build() instead of App::new(). In addition I didn't extract the sub app feature as it isn't ready yet.

You can use `git diff --diff-filter=M eb8f973646476b4a4926ba644a77e2b3a5772159` to find all differences in this PR. The `--diff-filtered=M` filters all files added in the original commit but not in this commit away.

d3ae816e3e Ci stability and speed improvements (#2551)
# Objective

- There are a few random failures in CI, mostly due to contacting crates.io or checking for deadlinks
- CI can take some time, more than 20 minutes for a full status
- A clippy/format issue stops running tests on other platforms


## Solution

- Use GitHub cache for cargo artefacts
  - This speeds up builds and reduce dependencies on outside world
- Reorder and add dependencies between short jobs. They are still setup to run even if one of the dependency failed
  - This reduce the number of parallel jobs that are running for one PR. On GitHub free tier, we're limited to 20.
- Split CI checks (format & clippy) in its own job
  - This speeds up test jobs, and allow us to not kill all platform tests for a format issue
- Retry in case of dead links check failure
  - Internet is just that kind of place where things may seem dead at some point but back alive 5 seconds later

5583f9a3bc Android uninstall 31 (#2533)
# Objective

- Related to #2514 - not sure if it's a proper fix long term
- CI was complaining Error: Path `"/usr/local/lib/android/sdk/ndk-bundle/toolchains/llvm/prebuilt/linux-x86_64/bin/aarch64-linux-android31-clang"` was not found
- A lot of questions started popping up 10 days ago about ["android build tools 31 corrupted"](https://www.google.com/search?q=android+build+tools+31+corrupted)
  - https://stackoverflow.com/questions/68387270/android-studio-error-installed-build-tools-revision-31-0-0-is-corrupted
- Uninstalling `"build-tools;31.0.0"` doesn't seem to work, as it removes other components even though `"build-tools;30.0.3"` are available


## Solution

- Uninstalling `"platforms;android-31"` seems to do the trick and `cargo-apk` stops trying to target `...31`

Android is not my thing, this solution was found with a lot of trials and errors. I am not sure how long term it is, I don't know the release schedule of android build tools, or if we need to target this 31 thing. I just wanted to stop all those failed ci everywhere...

e167a1d9cf Relicense Bevy under the dual MIT or Apache-2.0 license (#2509)
This relicenses Bevy under the dual MIT or Apache-2.0 license. For rationale, see #2373.

* Changes the LICENSE file to describe the dual license. Moved the MIT license to docs/LICENSE-MIT. Added the Apache-2.0 license to docs/LICENSE-APACHE. I opted for this approach over dumping both license files at the root (the more common approach) for a number of reasons:
  * Github links to the "first" license file (LICENSE-APACHE) in its license links (you can see this in the wgpu and rust-analyzer repos). People clicking these links might erroneously think that the apache license is the only option. Rust and Amethyst both use COPYRIGHT or COPYING files to solve this problem, but this creates more file noise (if you do everything at the root) and the naming feels way less intuitive. 
  * People have a reflex to look for a LICENSE file. By providing a single license file at the root, we make it easy for them to understand our licensing approach. 
  * I like keeping the root clean and noise free
  * There is precedent for putting the apache and mit license text in sub folders (amethyst) 
* Removed the `Copyright (c) 2020 Carter Anderson` copyright notice from the MIT license. I don't care about this attribution, it might make license compliance more difficult in some cases, and it didn't properly attribute other contributors. We shoudn't replace it with something like "Copyright (c) 2021 Bevy Contributors" because "Bevy Contributors" is not a legal entity. Instead, we just won't include the copyright line (which has precedent ... Rust also uses this approach).
* Updates crates to use the new "MIT OR Apache-2.0" license value
* Removes the old legion-transform license file from bevy_transform. bevy_transform has been its own, fully custom implementation for a long time and that license no longer applies.
* Added a License section to the main readme
* Updated our Bevy Plugin licensing guidelines.

As a follow-up we should update the website to properly describe the new license.

Closes #2373
