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
# Objective
- CI is failing because of an android issue
- This is blocking bors
## Solution
- Bors can ignore android failures
- Keep android job in CI to check its status
I'm not android enough to debug this one, this is a temp fix until someone knows how to fix it or it get fixed by itself with updates?
# Objective
@TomBebb (other account being @TomBebbington ) proved unreachable for #2373, so we need to revert their changes for the relicense.
## Solution
Revert their changes. This is only linux distro docs, so it's not critical code.
If someone else wants to test `bevy` on solus to work out the set of packages independently, then we'll probably accept a PR to add these. One suggestsion would be to consider the packages required on other systems, since there is likely to be some overlap.
## Alternatives
Link to this old version in the `linux_dependencies.md` file.
This obsoletes #1111 and #2445, since @ColonisationCaptain and @temhotaokeaha haven't replied to #2373.
I believe that both of those PRs would be fine to keep, but they're even more fine to keep now :)
# Objective
- Continue work of #2398 and friends.
- Make `.system()` optional in chaining.
## Solution
- Slight change to `IntoChainSystem` signature and implementation.
- Remove some usages of `.system()` in the chaining example, to verify the implementation.

I swear, I'm not splitting these up on purpose, I just legit forgot about most of the things where `System` appears in public API, and my trait usage explorer mingles that with the gajillion internal uses.
In case you're wondering what happened to part 5, #2446 ate it.
# Objective
Currently we can sometimes allow PRs by people who haven't agreed to the relicense to get merged into main.
E.g. https://github.com/bevyengine/bevy/pull/2445
## Solution
This adds a check to ensure that this doesn't happen, by ensuring that bors doesn't relicense said PRs.
As a bonus, it also adds config to automatically label new PRs as needing checking, to ensure that we do the verification until we merge the new license.
# Objective
- Currently `Commands` are quite slow due to the need to allocate for each command and wrap it in a `Box<dyn Command>`.
- For example:
```rust
fn my_system(mut cmds: Commands) {
cmds.spawn().insert(42).insert(3.14);
}
```
will have 3 separate `Box<dyn Command>` that need to be allocated and ran.
## Solution
- Utilize a specialized data structure keyed `CommandQueueInner`.
- The purpose of `CommandQueueInner` is to hold a collection of commands in contiguous memory.
- This allows us to store each `Command` type contiguously in memory and quickly iterate through them and apply the `Command::write` trait function to each element.
# Objective
This fixes a crash caused by iOS preventing GPU access when not focused: #2296
## Solution
This skips `app.update()` in `winit_runner` when `winit` sends the `Suspended` event, until `Resumed`.
I've tested that this works for me on my iOS app.
This was tested using cargo generate-lockfile -Zminimal-versions.
The following indirect dependencies also have minimal version
dependencies. For at least num, rustc-serialize and rand this is
necessary to compile on rustc versions that are not older than 1.0.
* num = "0.1.27"
* rustc-serialize = "0.3.20"
* termcolor = "1.0.4"
* libudev-sys = "0.1.1"
* rand = "0.3.14"
* ab_glyph = "0.2.7
Based on https://github.com/bevyengine/bevy/pull/2455
# Objective
Reduce compilation time
# Solution
Remove unused dependencies. While this PR doesn't remove any crates from `Cargo.lock`, it may unlock more build parallelism.

I struggled with some sprite sheet animation which was like drifting from right to left.
This PR documents the current behaviour that the padding which is used on slicing a texture into a texture atlas, is assumed to be only between tiles. In my case I had some padding also on the right side of the texture.
# Objective
Noticed a warning when running tests:
```
> cargo test --workspace
warning: output filename collision.
The example target `change_detection` in package `bevy_ecs v0.5.0 (/bevy/crates/bevy_ecs)` has the same output filename as the example target `change_detection` in package `bevy v0.5.0 (/bevy)`.
Colliding filename is: /bevy/target/debug/examples/change_detection
The targets should have unique names.
Consider changing their names to be unique or compiling them separately.
This may become a hard error in the future; see <https://github.com/rust-lang/cargo/issues/6313>.

```
## Solution
I renamed example `change_detection` to `component_change_detection`
In #2034, the `Remove` Command did not get the same treatment as the rest of the commands. There's no discussion saying it shouldn't have public fields, so I am assuming it was an oversight. This fixes that oversight.
# Objective
- Continue work of #2398 and friends.
- Make `.system()` optional in run criteria APIs.
## Solution
- Slight change to `RunCriteriaDescriptorCoercion` signature and implementors.
- Implement `IntoRunCriteria` for `IntoSystem` rather than `System`.
- Remove some usages of `.system()` with run criteria in tests of `stage.rs`, to verify the implementation.
# Objective
Fixes a possible deadlock between `AssetServer::get_asset_loader` / `AssetServer::add_loader`
A thread could take the `extension_to_loader_index` read lock,
and then have the `server.loader` write lock taken in add_loader
before it can. Then add_loader can't take the extension_to_loader_index
lock, and the program deadlocks.
To be more precise:
## Step 1: Thread 1 grabs the `extension_to_loader_index` lock on lines 138..139:
3a1867a92e/crates/bevy_asset/src/asset_server.rs (L133-L145)
## Step 2: Thread 2 grabs the `server.loader` write lock on line 107:
3a1867a92e/crates/bevy_asset/src/asset_server.rs (L103-L116)
## Step 3: Deadlock, since Thread 1 wants to grab `server.loader` on line 141...:
3a1867a92e/crates/bevy_asset/src/asset_server.rs (L133-L145)
... and Thread 2 wants to grab 'extension_to_loader_index` on lines 111..112:
3a1867a92e/crates/bevy_asset/src/asset_server.rs (L103-L116)
## Solution
Fixed by descoping the extension_to_loader_index lock, since
`get_asset_loader` doesn't need to hold the read lock on the extensions map for the duration,
just to get a copyable usize. The block might not be needed,
I think I could have gotten away with just inserting a `copied()`
call into the chain, but I wanted to make the reasoning clear for
future maintainers.
# Objective
- Describe the objective or issue this PR addresses.
- added openSUSE Tumbleweed deps that i needed to install today 2021-06-22
## Solution
- Describe the solution used to achieve the objective above.
- added info to doc
# Objective
I wanted to send the Bevy discord link to someone but couldn't find a pretty link to copy paste
## Solution
Use the vanity link we have for discord
# Objective
Fixes how the layer bit is unset in the RenderLayers bit mask when calling the `without` method.
## Solution
Unsets the layer bit using `&=` and the inverse of the layer bit mask.
# Objective
Beginners semi-regularly appear on the Discord asking for help with using `QuerySet` when they have a system with conflicting data access.
This happens because the Resulting Panic message only mentions `QuerySet` as a solution, even if in most cases `Without<T>` was enough to solve the problem.
## Solution
Mention the usage of `Without<T>` to create disjoint queries as an alternative to `QuerySet`
## Open Questions
- Is `disjoint` a too technical/mathematical word?
- Should `Without<T>` be mentioned before or after `QuerySet`?
- Before: Using `Without<T>` should be preferred and mentioning it first reinforces this for a reader.
- After: The Panics can be very long and a Reader could skip to end and only see the `QuerySet`

# Objective
- Continue work of #2398 and #2403.
- Make `.system()` syntax optional when using `.config()` API.
## Solution
- Introduce new prelude trait, `ConfigurableSystem`, that shorthands `my_system.system().config(...)` as `my_system.config(...)`.
- Expand `configure_system_local` test to also cover the new syntax.
# Objective
- Add inline documentation for `StorageType`.
- Currently the README in `bevy_ecs` provides docs for `StorageType`, however, adding addition inline docs makes it simpler for users who are actively reading the source code.
## Solution
- Add inline docs.
# Objective
- Extend work done in #2398.
- Make `.system()` syntax optional when using system descriptor API.
## Solution
- Slight change to `ParallelSystemDescriptorCoercion` signature and implementors.
---
I haven't touched exclusive systems, because it looks like the only two other solutions are going back to doubling our system insertion methods, or starting to lean into stageless. The latter will invalidate the former, so I think exclusive systems should remian pariahs until stageless.
I can grep & nuke `.system()` thorughout the codebase now, which might take a while, or we can do that in subsequent PR(s).
# Objective
- Currently the `Commands` and `CommandQueue` have no performance testing.
- As `Commands` are quite expensive due to the `Box<dyn Command>` allocated for each command, there should be perf tests for implementations that attempt to improve the performance.
## Solution
- Add some benchmarking for `Commands` and `CommandQueue`.
This can be your 6 months post-christmas present.
# Objective
- Make `.system` optional
- yeet
- It's ugly
- Alternative title: `.system` is dead; long live `.system`
- **yeet**
## Solution
- Use a higher ranked lifetime, and some trait magic.
N.B. This PR does not actually remove any `.system`s, except in a couple of examples. Once this is merged we can do that piecemeal across crates, and decide on syntax for labels.
# Objective
Re-introduce `AHashExt` and respective `with_capacity()` implementations to give a more ergonomic way to set a `HashMap` / `HashSet` capacity.
As a note, this has also been discussed and agreed on issue #2115, which this PR addresses (leaving `new()` out of the `AHashExt` trait).
Fixes#2115.
## Solution
PR #1235 had removed the `AHashExt` trait and respective `with_capacity()`s implementations, leaving only the less ergonomic `HashMap::with_capacity_and_hasher(size, Default::default())` option available.
This re-introduces `AHashExt` and respective `with_capacity()` implementations to give a more ergonomic way to set a `HashMap` / `HashSet` capacity.
# Objective
Currently, you can add `Option<Res<T>` or `Option<ResMut<T>` as a SystemParam, if the Resource could potentially not exist, but this functionality doesn't exist for `NonSend` and `NonSendMut`
## Solution
Adds implementations to use `Option<NonSend<T>>` and Option<NonSendMut<T>> as SystemParams.
Updates the requirements on [wgpu](https://github.com/gfx-rs/wgpu) to permit the latest version.
