From 4a9303124e6ab992d4c455e65da7052f70758e05 Mon Sep 17 00:00:00 2001 From: Jose Celano Date: Wed, 12 Nov 2025 08:50:44 +0000 Subject: [PATCH 1/5] feat: [#164] implement ReentrantMutex> pattern Replace Arc> with Arc>> throughout codebase to resolve same-thread reentrancy deadlock. Key changes: - Add parking_lot dependency for ReentrantMutex support - Update Container, ExecutionContext, and all controllers - Convert ProgressReporter to use ReentrantMutex pattern - Fix test infrastructure compatibility with parking_lot - Add comprehensive reentrancy verification tests - Update error handling to use ReentrantMutex pattern - Add architectural decision record for pattern choice All core functionality maintained while eliminating deadlock risk. Tests verify same-thread multiple lock acquisitions work correctly. --- Cargo.toml | 1 + docs/decisions/README.md | 35 +-- .../reentrant-mutex-useroutput-pattern.md | 224 +++++++++++++++++ docs/decisions/user-output-mutex-removal.md | 38 +-- project-words.txt | 1 + src/bootstrap/container.rs | 23 +- .../create/subcommands/environment/errors.rs | 4 -
