From 349bf05b962a8d3f4f84bfdc5dfc3c330418f00a Mon Sep 17 00:00:00 2001 From: Sergio Sisternes Date: Fri, 24 Apr 2026 19:57:17 +0100 Subject: [PATCH 01/12] refactor: complexity audit -- eliminate god-method forks, O(n^2) loops, redundant I/O Phase 0: Cache early lockfile on InstallContext (2x reads -> 1x); extract _parse_dependency_dict() classmethod in APMPackage. Phase 1: Thread-safety gate -- console singleton with double-checked locking; marketplace registry cache lock. Phase 2: Uninstall engine reverse-dep index O(n^2) -> O(n) via _build_children_index() helper. Phase 3: NullCommandLogger null-object pattern eliminates 32 conditional logger forks in MCPIntegrator (net -91 production lines). Phase 6: Primitive discovery -- replace 9+ glob.glob() calls with single os.walk + fnmatch pass. Registry: Pre-load installed IDs per runtime, reducing config reads from O(servers x runtimes) to O(runtimes). 54 new tests added (40 characterisation + 14 unit). 5,415 tests pass (baseline 5,361 + 54 new).
