From a82c81e8e3058ebe2cf3eaa698a50af2c6648e5e Mon Sep 17 00:00:00 2001 From: Christoffer Martinsson Date: Thu, 30 Oct 2025 11:00:36 +0100 Subject: [PATCH] Fix service control by adding .service suffix to systemctl commands Service stop/start operations were failing because systemctl commands were missing the .service suffix. This caused the new user-stopped tracking feature to mark services but not actually control them. Changes: - Add .service suffix to systemctl commands in service control handler - Matches pattern used throughout systemd collector - Fixes service start/stop functionality via dashboard Clean up legacy documentation: - Remove outdated TODO.md, AGENTS.md, and test files - Update CLAUDE.md with current architecture and rules only - Comprehensive README.md rewrite with technical documentation - Document user-stopped service tracking feature Bump version to v0.1.44 --- AGENTS.md | 3 - CLAUDE.md | 458 +++++++------------------------- README.md | 512 ++++++++++++++++-------------------- TODO.md | 63 ----- agent/Cargo.toml | 2 +- agent/src/agent.rs | 2 +- dashboard/Cargo.toml | 2 +- hardcoded_values_removed.md | 88 ------- shared/Cargo.toml | 2 +- test_intervals.sh | 42 --- test_tmux_check.rs | 32 --- test_tmux_simulation.sh | 53 ---- 12 files changed, 332 insertions(+), 927 deletions(-) delete mode 100644 AGENTS.md delete mode 100644 TODO.md delete mode 100644 hardcoded_values_removed.md delete mode 100755 test_intervals.sh delete mode 100644 test_tmux_check.rs delete mode 100644 test_tmux_simulation.sh diff --git a/AGENTS.md b/AGENTS.md deleted file mode 100644 index 111304b..0000000 --- a/AGENTS.md +++ /dev/null @@ -1,3 +0,0 @@ -# Agent Guide - -Agents working in this repo must follow the instructions in `CLAUDE.md`. diff --git a/CLAUDE.md b/CLAUDE.md index 3fc4866..0d44fa4 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -2,277 +2,57 @@ ## Overview -A high-performance Rust-based TUI dashboard for monitoring CMTEC infrastructure.
