Rename `wasm32-wasi` target to `wasm32-wasi-preview1` #607

yoshuawuyts · 2023-04-03T14:14:36Z

Proposal

This is a sibling MCP to: "New tier-2 target for wasm32-wasi-preview2" MCP. During the conversation on Zulip it came up that if we're going to be introducing wasm32-wasi-preview2, we should probably also rename the existing wasm32-wasi target to wasm32-wasi-preview1 in order to accurately set expectations. This is because eventually we'll want to deprecate the preview1 target, so it's probably best if we start communicating that in the name. Additionally we would also rename the wasm32-wasi-threads target to wasm32-wasi-preview1-threads.

Because we are not (yet) removing a target but only renaming it, we should be able to do this over a regular Rust release. This means we are not going to have a period where thewasm32-wasi and wasm32-wasi-preview1 targets are both available in the toolchain. In order to facilitate a smoother transition however, we may want to look into teaching the toolchain manager about "deprecated targets", so a better error can be issued for people looking to upgrade to a new Rust version where a target has been renamed or removed.

Process

The main points of the Major Change Process are as follows:

File an issue describing the proposal.
A compiler team member or contributor who is knowledgeable in the area can second by writing @rustbot second.
- Finding a "second" suffices for internal changes. If however, you are proposing a new public-facing feature, such as a -C flag, then full team check-off is required.
- Compiler team members can initiate a check-off via @rfcbot fcp merge on either the MCP or the PR.
Once an MCP is seconded, the Final Comment Period begins. If no objections are raised after 10 days, the MCP is considered approved.

Rename `wasm32-wasi` to `wasm32-wasi-preview1` Implements rust-lang/compiler-team#607

This commit adds a new target called `wasm32-wasip1` to rustc. This new target is explained in these two MCPs: * rust-lang/compiler-team#607 * rust-lang/compiler-team#695 In short, the previous `wasm32-wasi` target is going to be renamed to `wasm32-wasip1` to better live alongside the [new `wasm32-wasip2` target](rust-lang#119616). This new target is added alongside the `wasm32-wasi` target and has the exact same definition as the previous target. This PR is effectively a rename of `wasm32-wasi` to `wasm32-wasip1`. Note, however, that as explained in rust-lang/compiler-team#695 the previous `wasm32-wasi` target is not being removed at this time. This change will reach stable Rust before even a warning about the rename will be printed. At this time this change is just the start where a new target is introduced and users can start migrating if they support only Nightly for example.

This commit is a continuation of the work originally proposed in rust-lang/compiler-team#607 and later amended in rust-lang/compiler-team#695. The end goal is to rename `wasm32-wasi` to `wasm32-wasip1` to reflect WASI's development and distinguish the preexisting target from the `wasm32-wasip2` target that WASI is now developing. Work for this transition began in rust-lang#120468 which landed in Rust 1.78 which became stable on 2024-05-02. This implements the next phase of the transition plan to warn on usage of `wasm32-wasi`. This is intended to help alert users that a removal is pending and all release channels have the replacement available as well. This will reach stable on 2024-09-05. The next stage of the plan is to remove the `wasm32-wasi` target some time in October 2024 which means that the removal will reach stable on 2025-01-09. For reference a full schedule of this transition is listed [here]. Currently this implementation is a simple unconditional warning whenever `rustc --target wasm32-wasi` is invoked. As-implemented there's no way to turn off the warning other than to switch to the `wasm32-wasip1` target. [here]: rust-lang#120468 (comment)

This commit is the final step in the journey of renaming the historical `wasm32-wasi` target in the Rust compiler to `wasm32-wasip1`. Various steps in this journey so far have been: * 2023-04-03: rust-lang/compiler-team#607 - initial proposal for this rename * 2024-11-27: rust-lang/compiler-team#695 - amended schedule/procedure for rename * 2024-01-29: rust-lang#120468 - initial introduction of `wasm32-wasip1` * 2024-06-18: rust-lang#126662 - warn on usage of `wasm32-wasi` * 2024-11-08: this PR - remove the `wasm32-wasi` target The full transition schedule is in [this comment][comment] and is summarized with: * 2024-05-02: Rust 1.78 released with `wasm32-wasip1` target * 2024-09-05: Rust 1.81 released warning on usage of `wasm32-wasi` * 2025-01-09: Rust 1.84 to be released without the `wasm32-wasi` target This means that support on stable for the replacement target of `wasm32-wasip1` has currently been available for 6 months. Users have already seen warnings on stable for 2 months about usage of `wasm32-wasi` and stable users have another 2 months of warnings before the target is removed from stable. This commit is intended to be the final step in this transition so the source tree should no longer mention `wasm32-wasi` except in historical reference to the older name of the `wasm32-wasip1` target.
