…agnostic-handler-refactor, r=davidtwco Move and rename `SessionDiagnostic` & `SessionSubdiagnostic` traits and macros After PR rust-lang#101434, we want to: - [x] Move `SessionDiagnostic` to `rustc_errors`. - [x] Add `emit_` methods that accept `impl SessionDiagnostic` to `Handler`. - [x] _(optional)_ Rename trait `SessionDiagnostic` to `DiagnosticHandler`. - [x] _(optional)_ Rename macro `SessionDiagnostic` to `DiagnosticHandler`. - [x] Update Rustc Dev Guide and Docs to reflect these changes. rust-lang/rustc-dev-guide#1460 Now I am having build issues getting the compiler to build when trying to rename the macro. <details> <summary>See diagnostics errors and context when building.</summary> ``` error: diagnostics should only be created in `SessionDiagnostic`/`AddSubdiagnostic` impls --> compiler/rustc_attr/src/session_diagnostics.rs:13:10 | 13 | #[derive(DiagnosticHandler)] | ^^^^^^^^^^^^^^^^^ in this derive macro expansion | ::: /Users/jhonny/.cargo/registry/src/github.51.al-1ecc6299db9ec823/synstructure-0.12.6/src/macros.rs:94:9 | 94 | / pub fn $derives( 95 | | i: $crate::macros::TokenStream 96 | | ) -> $crate::macros::TokenStream { | |________________________________________- in this expansion of `#[derive(DiagnosticHandler)]` | note: the lint level is defined here --> compiler/rustc_attr/src/lib.rs:10:9 | 10 | #![deny(rustc::diagnostic_outside_of_impl)] | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ``` And also this one: ``` error: diagnostics should only be created in `SessionDiagnostic`/`AddSubdiagnostic` impls --> compiler/rustc_attr/src/session_diagnostics.rs:213:32 | 213 | let mut diag = handler.struct_span_err_with_code( | ^^^^^^^^^^^^^^^^^^^^^^^^^ ``` > **Note** > Can't find where this message is coming from, because you can see in [this experimental branch](https://github.com/JhonnyBillM/rust/tree/experimental/trying-to-rename-session-diagnostic-macro) that I updated all errors and diags to say: > error: diagnostics should only be created in **`DiagnosticHandler`**/`AddSubdiagnostic` impls > and not: > error: diagnostics should only be created in **`SessionDiagnostic`**/`AddSubdiagnostic` impls </details> I tried building the compiler in different ways (playing with the stages etc), but nothing worked. ## Question **Do we need to build or do something different when renaming a macro and identifiers?** For context, see experimental commit JhonnyBillM@f2193a9 where the macro and symbols are renamed, but it doesn't compile.
