From 0ef032ccc8a25ba670615e1a000990767b1cf6b8 Mon Sep 17 00:00:00 2001 From: nyash-codex Date: Thu, 18 Dec 2025 18:28:37 +0900 Subject: [PATCH] refactor(smokes): Task 5 - Environment variable SSOT centralization MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Create single source of truth for smoke test environment configuration: **tools/smokes/v2/lib/env.sh** (new, 183 lines): - Centralize 16 environment variables across 6 categories - JoinIR development (NYASH_JOINIR_DEV, HAKO_JOINIR_STRICT) - LLVM features (NYASH_LLVM_USE_HARNESS, NYASH_LLVM_BACKEND, etc.) - Tmpdir EXDEV mitigation (TARGET_TMPDIR) - Plugin loader strategy (NYASH_LOAD_NY_PLUGINS, NYASH_DISABLE_PLUGINS) - Parser features (NYASH_FEATURES, using system variables) - Debug features (NYASH_CLI_VERBOSE, etc.) **Mode Presets**: - dev: Verbose logging, unlimited fuel, JoinIR dev enabled - integration: Moderate settings, JoinIR dev enabled - quick: Minimal logging, fast execution **Helper Functions**: - setup_smoke_env [mode]: Configure environment for test profiles - validate_env_setup: Validate configuration - show_smoke_env: Display current configuration **Documentation**: - ENV_README.md: Comprehensive usage guide - ENV_QUICK_START.md: Quick reference for script authors - p1.5-task5-env-ssot.md: Implementation details and testing Benefits: - SSOT: Single file for all environment variables - Sparrow prevention: No duplicate settings - Clarity: Well-documented configuration - Backward compatibility: Existing scripts work unchanged Test Results: - All environment presets work correctly - Phase 131 smoke tests PASS - Syntax validation for all shell files PASS Related: Phase 131 smoke test infrastructure improvement 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Haiku 4.5 --- .../phases/phase-131/p1.5-task5-checklist.md | 191 +++++++++++ .../phases/phase-131/p1.5-task5-env-ssot.md | 263 ++++++++++++++++ tools/smokes/v2/lib/ENV_QUICK_START.md | 81 +++++ tools/smokes/v2/lib/ENV_README.md | 296 ++++++++++++++++++ tools/smokes/v2/lib/env.sh | 183 +++++++++++ 5 files changed, 1014 insertions(+) create mode 100644 docs/development/current/main/phases/phase-131/p1.5-task5-checklist.md create mode 100644 docs/development/current/main/phases/phase-131/p1.5-task5-env-ssot.md create mode 100644 tools/smokes/v2/lib/ENV_QUICK_START.md create mode 100644 tools/smokes/v2/lib/ENV_README.md create mode 100644 tools/smokes/v2/lib/env.sh diff --git a/docs/development/current/main/phases/phase-131/p1.5-task5-checklist.md b/docs/development/current/main/phases/phase-131/p1.5-task5-checklist.md new file mode 100644 index 00000000..072cf2ac --- /dev/null +++ b/docs/development/current/main/phases/phase-131/p1.5-task5-checklist.md @@ -0,0 +1,191 @@ +# Phase 131 Task 5 Implementation Checklist + +**Task**: Environment Variable SSOT Implementation +**Date**: 2025-12-18 +**Status**: ✅ COMPLETE + +## Pre-Implementation Checklist + +- [x] Analyze current environment variable usage across smoke tests +- [x] Identify duplicate settings (JOINIR_DEV, LLVM_USE_HARNESS, TMPDIR, etc.) +- [x] Determine scope of variables to centralize (16 variables identified) +- [x] Design env.sh structure with mode presets +- [x] Plan backward compatibility strategy + +## Implementation Checklist + +### Core Files + +- [x] Create `tools/smokes/v2/lib/env.sh` (183 lines) + -
