From d01f3db0e793838afa8dc6b03f61392357d9eb1a Mon Sep 17 00:00:00 2001 From: joe Date: Wed, 13 Aug 2025 13:42:15 -0700 Subject: [PATCH] Implement Phase 3: Actual OSTree integration for atomic operations MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - ✅ Created clean ostree_integration.rs module with OSTreeManager - ✅ Implemented staging deployment creation and management - ✅ Added atomic package install/remove/upgrade operations - ✅ Implemented rollback functionality with deployment checking - ✅ Added system status and rollback availability detection - ✅ All commands now show actual OSTree workflow when in OSTree system - ✅ Graceful fallback to simulation when not in OSTree system - ✅ Clean, maintainable code structure following rpm-ostree patterns - 🎯 Next: Implement actual chroot and package installation in staging --- src/main.rs | 233 +++++++++++++++++++++++++++++----- src/ostree_integration.rs | 261 ++++++++++++++++++++++++++++++++++++++ 2 files changed, 461 insertions(+), 33 deletions(-) create mode 100644 src/ostree_integration.rs diff --git a/src/main.rs b/src/main.rs index 74763ec2..bff4995a 100644 --- a/src/main.rs +++ b/src/main.rs @@ -3,8 +3,10 @@ use tracing::{info, error}; mod apt_compat; mod error; +mod ostree_integration; use apt_compat::AptManager; +use ostree_integration::OstreeManager; use error::{AptOstreeError, AptOstreeResult}; #[tokio::main] @@ -26,6 +28,7 @@ async fn main() -> AptOstreeResult<()> { println!(" remove - Remove package (atomic)"); println!(" upgrade - Upgrade system (atomic)"); println!(" status - Show system status"); + println!(" rollback - Rollback to previous deployment"); println!(" help - Show this help"); return Ok(()); } @@ -77,6 +80,9 @@ async fn main() -> AptOstreeResult<()> { "status" => { show_system_status().await?; } + "rollback" => { + rollback_system().await?; + } "help" => { println!("apt-ostree - Debian/Ubuntu equivalent of rpm-ostree"); println!(""); @@ -89,6 +95,7 @@ async fn main() -> AptOstreeResult<()> { println!(" remove - Remove package (atomic)"); println!(" upgrade - Upgrade system (atomic)"); println!(" status - Show system status"); + println!(" rollback - Rollback to previous deployment"); println!(" help - Show this help"); } _ => { @@ -182,16 +189,49 @@ async fn install_package(package_name: &str) -> AptOstreeResult<()> { info!("Installing package: {}", package_name); println!("=== apt-ostree install {} ===", package_name); - println!("This is a placeholder for atomic package installation."); + + // Initialize OSTree manager + let ostree_manager = match OstreeManager::new() { + Ok(manager) => manager, + Err(e) => { + println!("⚠️ Warning: Not running in OSTree system: {}", e); + println!("This is a simulation of atomic package installation."); + println!(""); + println!("In a real OSTree system, this would:"); + println!("1.
