…argets Run `cargo fix --workspace --all-targets` now that the workspace test targets compile again, so test-only imports are seen instead of pruned. Clears 87 warnings: 74 unused_imports, 11 function_casts_as_integer (new in rustc 1.95 — casting a function item straight to an integer), plus one each of unused_mut and unused_variables. Two things the tool could not do on its own: - optimized_libs/tests.rs reached build_missing_prebuilt_ext_lib through `super::*`, so cargo fix pruned the re-export it needed. The test now imports the function from no_auto directly. - 49 of the pruned imports were duplicate preambles introduced when commands/compile.rs was split into submodules after #6639.
rustc reports these as `unused_unsafe`: the block wraps code that needs no unsafe context, so the marker hides the sites that do. rustc gives no machine-applicable fix, so this was scripted off the diagnostic byte spans. Where the block only held expressions or statements, the block goes with the keyword. Where it held a top-level `let`, `use`, or item, only the keyword goes and the braces stay — splicing those into the enclosing scope would widen the binding and could silently re-resolve a later name. 106 blocks removed, 44 kept as plain scoping blocks.
handle_dispatch.rs declares `js_node_http_res_write` and `js_node_http_res_end` in an `extern "C"` block, but perry-ext-http-server defines both itself (response.rs:1136 and response.rs:1393). Nothing calls the declarations, so rustc reports them as dead functions. Both signatures matched their definitions, so the deletion is a no-op at link time. The other ~62 declarations in that block are used and stay for now; they carry the same hazard — a local declaration of a symbol you also define is never checked against the definition, which is how #6646 shipped an ABI mismatch on `len: i64` vs `u32`. Tracked separately.
Deletes refactor leftovers — helpers, thunks, fields and constants nothing calls any more. Keeps, with a justified `#[allow(dead_code)]`, the GC verifiers, the `#[cfg(test)]`-only helpers and the FFI keepalives that exist to be reachable from generated code rather than from Rust. No `#[no_mangle]` function is deleted, so no symbol the compiler emits calls to can go missing at link time. The 11 deleted `extern "C"` items are Rust-internal closure thunks addressed by function pointer, which rustc tracks precisely. Rebased from the triage done on 2026-07-18, so three sites needed fixing against current main: - `path::resolve_win32_str` is no longer dead — url/node_compat.rs calls it. Restored. - `class_field_inline_guard_enabled` and `test_reset_class_field_inline_guard` arrived after that triage (#6802). Kept. - The CGContext* declarations in widgets/chart.rs were already removed by #6646. Kept removed.
…arnings Four triaged families, rebased onto current main: - non_snake_case: the generated `thunk_<module>_<jsName>` wrappers keep the JS spelling on purpose, so the allow sits on the three thunk macros and the node_submodule thunks rather than on each site. Real Rust names renamed. - private_interfaces / private_bounds: widen the leaked types to `pub(crate)` so the signature matches what callers can already reach. - unreachable_patterns: 32 duplicate match arms. Each was checked against the arm that shadows it — all are literal repeats, none had a different body that the first arm was swallowing. - unreachable_code: two `return js_throw(..)` where `js_throw` returns `!`. - sqlite `Connection::set_limit` returned a discarded `Result`: propagated with `?` in connection.rs, and `let _` in dispatch.rs where the limit id is already validated. - unused_doc_comments: 8 `///` comments on statements, which rustdoc drops. - Four dead bindings whose right-hand side is pure, so the binding goes instead of getting an underscore. Conflicts against main resolved in favour of main: perry-hir switched to `crate::types::Type`, and object/mod.rs moved the transition cache into `RuntimeState`.
- objc2 deprecations: 17 `msg_send!` invocations were missing the comma between arguments, plus one `Retained::cast` swapped for the `cast_unchecked` the sibling widgets already use. - Vacuous glob re-exports: `pub use child::*` where every item in the child is `pub(super)` re-exports nothing, which is what rustc was reporting. Narrowed each to the visibility it actually has — two to `pub(crate)`, six to a plain `use` — instead of silencing the lint. - `native_proof_*` integration tests share one HIR builder toolkit and each file drives a subset, so the allow sits on the file with that reason. - issue_4914_cluster_port_sharing.rs: its only test is gated to non-macOS unix; the helpers and imports now carry the same gate. - `duplex_allow_half_open_defaults_true_and_honors_false_option` had no `#[test]`, so it had never run. Added. - `test_seed_class_parent_closure_root` existed twice, both writing the same `CLASS_PARENT_CLOSURES` static. Deleted the unreachable copy. - `WIDE_KEY_INDEX_CAPACITY` is a leftover of the 4-entry LRU that #6759 C1 replaced with shape records. - crash_log.rs took a shared reference to a `static mut` inside a signal handler; now `&raw const`. - Two dead stores removed (`idx`, `adjusted_args_storage`). The third, `done` in publish, is kept with a comment: rustc is right that the store is never read, and that means the reconnect guard it feeds can never fire — a protocol question, not a lint one. - Four test names de-camel-cased, one duplicated `#[test]` removed. `cargo check --workspace --all-targets` now reports zero warnings for the host-compatible scope. The cross-host UI crates (ios/tvos/watchos/visionos/ android/windows/gtk4) cannot be checked from macOS and are untouched.
`perry` depends on perry-runtime with `default-features = false`, so `cargo clippy -p perry --bins` — the product leg in CI — compiles a runtime where regex-engine, diagnostics and temporal are off. Eleven items are live under the workspace feature set and dead under that one, and the workspace check never saw them. Each is now gated at the item rather than silenced: - `array_named_props_install_fresh` and `regex::utf16::utf16_index_to_byte` are called only from regex-engine modules; both, and the array re-export, carry that feature (the cross-gate shape regex/utf16.rs already documents). - Four `fs::dir_glob_watch::glob` imports serve regex-engine-gated code and now match the `PathBuf` import next to them. - The two `AllocatorMaintenance*` enums and `TemporalLocaleCtx` are built from `diagnostics` and `temporal` code respectively, so the allow applies only when that feature is off. - publish's `done` allow moved to the function: a statement-level attribute does not affect `unused_assignments`. Four scopes now report zero warnings: `--workspace --all-targets`, `-p perry --bins`, `-p perry-runtime --no-default-features`, and `-p perry-runtime -p perry-stdlib -p perry-runtime-static -p perry-stdlib-static`.
Nothing stopped a PR from adding a warning: `lint` runs only `cargo fmt --check`, and `clippy` exits non-zero only on the deny-level lints in `[workspace.lints]`. The 96 unused imports this branch removed include 49 that reappeared within four days of #6639, from a file split that copied whole import preambles into each new submodule — the gate is what stops that. Two legs, because they compile different code. `perry` depends on perry-runtime with `default-features = false`, so the product leg sees a runtime with regex-engine, diagnostics and temporal off. The workspace leg passes `--all-targets` so test and bench targets count. Separate from the clippy job on purpose: clippy's warn-level lints stay informational, rustc's do not. perry-ui-macos sits in the excluded scope (this runs on ubuntu), so its warnings are not gated here.

CI runs `dtolnay/rust-toolchain@stable`, which is 1.97.1 on the runners; the local default stable here is 1.97.1's predecessor, 1.95.0, which does not have this lint yet. `length(1.0)` in the TUI layout pass inferred `f32` by fallback rather than by the `From<f64>` bound, which rustc is phasing out (rust-lang/rust#154024). Spelling the literal `1.0_f32` says what was already meant. It was the only occurrence. All four scopes re-checked under 1.97.1 report zero warnings.
The macOS host cannot see these; the first CI run on this branch found them. `commands::sandbox_profile` is the #506 MVP, macOS-only by design — its only caller is inside `#[cfg(target_os = "macos")]`, so off macOS all three of its functions are unreachable. The module declaration now carries the same gate as its caller instead of compiling into a build that can never call it. Verified by flipping both cfgs to a target this host is not, and checking: no errors, no warnings. The Linux linker branch in `platform_cmd.rs` binds `let mut c`, but only the `#[cfg(not(target_os = "linux"))]` cross-compile block mutates it, so building on Linux the `mut` is dead. Scoped allow on the binding, which does apply to `unused_mut` — verified by flipping the target and watching the warning disappear.

Keep the HTTP/2 authority resolver crate-visible.
crates/perry-ext-http-server/src/http2_server/session.rs still depends on h2_listening_server_for_authority when resolving a client session’s local server handle. Restore this re-export, or update every caller to import the defining module directly.
Proposed fix

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Apple Foundation NSImage initWithCGImage:size: returns new object Retained object documentation
💡 Result:
The NSImage initializer initWithCGImage:size: creates a new NSImage object that references the provided CGImage [1]. Regarding memory management, when you use this initializer, the underlying CGImage is maintained by the NSImage for its use [1]. It is standard Cocoa convention that the caller is not responsible for releasing the CGImage after passing it to this initializer [1]. The CGImage remains valid for the life of the NSImage object or as otherwise required by the framework's internal management [1]. You do not need to manually retain or release the CGImage passed into this method, as the system handles the necessary reference counting [1]. Older methods related to data retention, such as setDataRetained: and isDataRetained, have been deprecated since Mac OS X 10.6, as modern NSImage implementations manage image data efficiently without requiring manual retention flags [2].

Adopt the +1 result from initWithCGImage:size: instead of retaining it again.
init-style Objective-C methods on the result of alloc return an already-owned (+1) object; using Retained::retain here increments ownership again. The current loop increments the returned object’s retain count once per QR image and leaves an extra retained object behind via mem::forget.
Proposed ownership fix
- let ns_image: Retained<NSImage> = Retained::retain(ns_image_raw as *mut NSImage)?;
- // Balance the retain (init already gives us +1)
- std::mem::forget(Retained::retain(ns_image_raw as *mut NSImage));
+ // SAFETY: initWithCGImage:size: returns an owned (+1) object.
+ let ns_image: Retained<NSImage> =
+ unsafe { Retained::from_raw(ns_image_raw as *mut NSImage)? };🤖 Prompt for AI Agents

Preserve the Windows backend_disabled_msg re-export.
crates/perry/src/commands/compile/run_pipeline.rs imports this module via use super::* and calls backend_disabled_msg(...) when backend-wasm is disabled. Removing the symbol from the Windows re-export makes that configuration fail to compile.
Restore the re-export or import the helper directly in run_pipeline.rs.

Windows re-export of backend_disabled_msg in the compile command module, or
import it directly in run_pipeline.rs so its existing use through use super::*
remains available when backend-wasm is disabled.
The import block read:
#[cfg(unix)]
use std::os::unix::fs::{MetadataExt, PermissionsExt};
#[cfg(unix)]
use std::os::unix::io::AsRawFd;
use std::path::Path;
`cargo fix` deleted the unused `AsRawFd` line and left its `#[cfg(unix)]`
behind, which then applied to the `Path` import below it. Every unix host still
compiled; Windows failed with four `cannot find type Path` errors.
Swept the whole diff for the same shape — an attribute that outlived the item
it was written for — and this was the only one. The other new cfg/import
adjacencies are deliberate.

unused_unsafe(150). rustc gives no machine-applicable fix, so this was scripted off the diagnostic byte spans. Where the block held only expressions or statements, the block went with the keyword (106). Where it held a top-levellet,use, or item, only the keyword went and the braces stayed (44) — splicing those into the enclosing scope widens the binding and can silently re-resolve a later name.dead_code(121). Rebased from the 2026-07-18 triage. No#[no_mangle]function is deleted, so nothing the compiler emits calls to can go missing at link time; the 11 deletedextern "C"items are Rust-internal closure thunks addressed by function pointer, which rustc tracks precisely. GC verifiers,#[cfg(test)]helpers and FFI keepalives are kept with a justified allow. Three sites needed fixing against current main:path::resolve_win32_stris called again byurl/node_compat.rs, and twoclass_field_inline_guardhelpers arrived after that triage (perf(runtime): #6759 C5a — per-key vetting for the class-field inline-guard disable #6802).pub use child::*where every item in the child ispub(super)re-exports nothing — narrowed each to the visibility it actually has (twopub(crate), six plainuse) rather than adding an allow.perrydepends on perry-runtime withdefault-features = false, socargo clippy -p perry --binscompiles a runtime with regex-engine, diagnostics and temporal off, where items the workspace check finds live are dead.
