From 89734a879bb2b00995cea99951b3f593e57e98c8 Mon Sep 17 00:00:00 2001 From: Adam Eivy Date: Thu, 3 Sep 2026 02:27:31 +0000 Subject: [PATCH 1/2] refactor: give the autofixer one shared module for PM2 execution, data paths and app loading (#5732) autofixer/server.js (the repair loop) and autofixer/ui.js (the dashboard) carried byte-identical copies of their shared plumbing: PM2_BIN resolution, the execPm2 promise wrapper, the DATA_DIR/APPS_FILE/AUTOFIXER_DIR/INDEX_FILE constants and loadApps(). The Windows rationale for resolving PM2's JS entry point instead of pm2.cmd was documented twice and would have had to be fixed twice. Both processes now import autofixer/shared.js, which resolves the data directory from its own location so the two PM2 processes can never disagree about which data/ they are reading. server.js keeps its own PROVIDERS_FILE, SETTINGS_FILE, SESSIONS_DIR and WORKTREES_DIR. Behavior is unchanged. The new suite pins that PM2_BIN still points at an existing bin/pm2 (a PM2 layout change would otherwise surface only at runtime, on the next repair), that every path anchors to the package-sibling data/ directory, and that loadApps() falls back to [] instead of throwing. It self-skips where the root node_modules is absent, since CI installs only server/node_modules.
