This is an updated version of #1434 PR. I've encountered this macro problem while trying to use @woubuc's bevy-event-set crate.
Co-authored-by: Piotr Balcer <piotr@balcer.eu>
I didn't know about MinimalPlugins for way too long. This should increase visibility for others.
# Objective
Improve visibility and discover in the docs for Default and Minimal Plugins.
## Solution
Links the two Docs pages.
Co-authored-by: Mirko Rainer <52899592+mirkoRainer@users.noreply.github.com>
# 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.
## Objective
This code would result in a crash:
```rust
use bevy::prelude::*;
fn main() {
let mut world = World::new();
let child = world.spawn().id();
world.spawn().push_children(&[child]);
}
```
## Solution
Update the `EntityMut`'s location after inserting a component on the children entities, as it may have changed.
# Objective
- #2551 revamped our CI setup which included running clippy and rustfmt in another Job.
- This new Job wasn't added to the bors.toml, which means that PRs would be accepted that didn't run them.
## Solution
- Add the "ci" job to the bors.toml
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)
# 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.
# 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
# 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...
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.

This logic was in both `remove_bundle` and ` remove_bundle_intersection` but only differed by whether we call `.._forget_missing_..` or `.._drop_missing_..`
# 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

# 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...
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.
