From d4f8f890167bad3f56fe5438741fb3cec3761889 Mon Sep 17 00:00:00 2001 From: Jeroen Schweitzer Date: Sun, 17 May 2026 22:11:23 +0200 Subject: [PATCH] code-quality batch (T-112) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Seven small consultant findings, one commit: 1. TreeSitterLib stores last dlopen error + path in static fields instead of swallowing them. Callers that observe a null instance can now read the diagnostic. 2. Drop the Cmsghdr alias in libc.dart — back-compat shim with no callers; CLAUDE.md forbids those in a solo repo. 3. Drop EditorController._events field + the unused_field suppression. The constructor still subscribes via `events.on<...>` for _eventSub; the field itself was speculative retention. 4. Replace inline hex / errno literals in native_pty.dart with PosixErrno.{eintr,ebadf,epipe} and new libc.{pollin, pollAnyErr, sighup, sigkill, sigwinch}. PosixErrno gains eintr. 5. ExtensionManager records activate/deactivate exceptions in a `_failed` map exposed as `failedExtensions` + `didFail(id)`. Listeners are notified on entry/exit; cleared on a clean activate. UI surfaces the degraded state instead of pretending everything is fine. 6. file_tree_view imports FileEntry via the clide.dart barrel instead of `package:clide/src/files/listing.dart` directly — the leak the consultant flagged (barrel already re-exports it). 7. test_app branch in main.dart wrapped in `if (kDebugMode)` so release tree-shaker elides the test harness from shipping binaries. Source import stays; tree-shake handles the rest.
