@claude[agent] fix oxc upgrade compile errors

Fixed the oxc 0.125.0 compilation errors in commits 2e444d1 and ac26587.

Changes made:

Fixed import paths: CompactStr, Ident, and Str moved from oxc::span to new locations
CompactStr and Ident now come from the oxc_str crate
Str moved to oxc::ast::ast
Added oxc_str dependency to workspace and affected crates
Fixed TypeScriptOptions: added missing optimize_enums field
Fixed TreeShakeOptions: added missing property_write_side_effects field (now a bool)
Updated Ident constant creation to use static_ident! macro instead of Ident::new_const()
Updated test_this_expression test for oxc 0.125.0 behavior change (now considers this to have side effects)
Ran codegen to update generated files with new version

All compilation errors are resolved. The changes are ready for review.

@claude[agent] commit the new generated packages/rolldown/src/binding.d.cts diff too by running just build-rolldown

Done! Regenerated packages/rolldown/src/binding.d.cts by running just build-rolldown and committed the changes in 0be967f.

The generated file now includes the new propertyWriteSideEffects field in the TreeShakeOptions interface.

@claude[agent] fix ci

@claude[agent] fix ci

Fixed the CI failures in commit 805e530:

Removed unused span import in crates/rolldown/src/ast_scanner/dynamic_import.rs
Added missing propertyWriteSideEffects field to CompressTreeshakeOptionsSchema in packages/rolldown/src/utils/validator.ts

The CI should pass now.

Dunqing

I've reviewed propertyWriteSideEffects and enum related changes and all look good to me.

- Fix import paths: CompactStr, Ident, and Str moved from oxc::span - CompactStr and Ident now come from oxc_str crate - Str moved to oxc::ast::ast - Add oxc_str dependency to workspace and affected crates - Fix TypeScriptOptions: add optimize_enums field - Fix TreeShakeOptions: add property_write_side_effects field (bool) - Update Ident constant creation to use static_ident! macro - Run codegen to update generated files with new version Agent-Logs-Url: https://github.com/rolldown/rolldown/sessions/02210b8f-d3a1-4d4d-a6fb-9bdaf9d6d6b1 Co-authored-by: Brooooooklyn <3468483+Brooooooklyn@users.noreply.github.com>

In oxc 0.125.0, `this` is now considered to potentially have side effects because it may be used in contexts where accessing `this` could throw.

-counter.value++;
-(class {
-	static {
-		++counter.count;
-	}
-});
-counter.another++;
 console.log(counter);


I think we shouldn't remove these because counter is used.

@Dunqing cc

[counter.another++] = 123; // Should not be tree-shaken, since counter is used

Oxc doesn't seem to handle this correctly. We need to disable property_write_side_effects here until we fix it in Oxc.

I think both counter.value++ and ++counter.count should be kept as well, not only counter.another++. I think the comment for counter.value++ was not updated correctly in 4838d5f.
console.log(counter) is added in that commit so counter.value++ shouldn't be removed anymore.

you are right, all will affect reading

…ectful `obj.prop++` performs an implicit GetValue + ToNumeric + PutValue. The ToNumeric coercion alone can invoke `valueOf`/`Symbol.toPrimitive` on the old value, and the read/write may trigger getters, setters, or Proxy traps. Previously `UpdateExpression::may_have_side_effects` only checked `property_write_side_effects()` and treated the update as free when disabled — letting the minifier drop `counter.value++` even when `counter` is externally observable. Terser, esbuild, Rollup, and SWC all hardcode `++`/`--` as unconditionally side-effectful; match that (mirrors how compound assignments like `a.b += 1` are already handled one impl above). Reported via rolldown/rolldown#9094.

…ectful (#21456) ## Summary `obj.prop++` performs an implicit `GetValue` + `ToNumeric` + `PutValue`. The `ToNumeric` coercion alone can invoke `valueOf`/`Symbol.toPrimitive` on the old value, and the read/write may trigger getters, setters, or Proxy traps. Previously `UpdateExpression::may_have_side_effects` only checked `property_write_side_effects()` and treated the update as free when disabled — letting the minifier drop `counter.value++` even when `counter` is externally observable. ## Fix Return `true` unconditionally for `UpdateExpression`. Terser, esbuild, Rollup, and SWC all hardcode `++`/`--` as unconditionally side-effectful — this matches their behavior, and mirrors how compound assignments like `a.b += 1` are already handled one impl above (`AssignmentExpression`). ## Impact Under rolldown's tree-shake config (`propertyWriteSideEffects: false`), these are now correctly preserved instead of being dropped: ```js counter.value++; (class { static { ++counter.count; } }); class A { [counter.another++] = 123; } ``` ## Reported rolldown/rolldown#9094 ([comment](rolldown/rolldown#9094 (comment)))
