Aims to be a Reproducible Minecraft Workspace Manager. https://git.hydroroll.team/DropOut/atom?h=dropout-v0.2.0-alpha.1 2026-01-18T06:27:45Z 2026-01-18T06:27:45Z HsiangNianian i@jyunko.cn 2026-01-18T06:27:45Z urn:sha1:6fdb730c323bcb1b052a2f9b13034603cbaf1e4d - Sync instance.version_id after start_game, install_fabric, install_forge - Add jvm_args_override and memory_override to Instance struct - Add file management commands: list_instance_directory, delete_instance_file, open_file_explorer - Support per-instance settings overrides (Java args, memory) 2026-01-18T05:43:12Z HsiangNianian i@jyunko.cn 2026-01-18T05:43:12Z urn:sha1:17e8dd78ca5b7aae9baa4f86d38fa755c8af21c5 - Add migrate_to_shared_caches() with hard link preference - SHA1-based deduplication across all instances - Copy fallback for cross-filesystem scenarios - Auto-enable use_shared_caches after successful migration - UI shows statistics: moved files, hardlinks/copies, MB saved 2026-01-18T05:34:52Z HsiangNianian i@jyunko.cn 2026-01-18T05:34:52Z urn:sha1:02520ca62ac5e508e8748b2445171be64f459b6c - Add pass_filenames: false to fmt hook - Add -- separator for cargo fmt args - Manually format code with cargo fmt 2026-01-18T04:58:22Z HsiangNianian i@jyunko.cn 2026-01-18T04:58:22Z urn:sha1:5e9850881d35d3af9ae8a2f99402e02300f77835 ## Overview Fixed critical multi-instance isolation bugs where versions, mod loaders, and instance state were not properly isolated between instances. These changes ensure full data isolation and consistent instance metadata. ## Bug Fixes - P0 (Critical Isolation Issues) ### 1. Backend: get_versions() command isolation - Problem: Used global app_data_dir instead of instance-specific game_dir - Fix: Added instance_id parameter, now queries instance.game_dir - Impact: Versions are now properly isolated per instance ### 2. Frontend: delete_version missing instanceId - Problem: Frontend passed only versionId, not instanceId - Fix: Updated VersionsView.svelte to pass instanceId parameter - Impact: Version deletion now targets correct instance ### 3. Frontend: get_version_metadata missing instanceId - Problem: Metadata queries didn't specify which instance to check - Fix: Updated VersionsView.svelte to pass instanceId parameter - Impact: Version info displayed per-instance correctly ### 4. Frontend: Instance switching doesn't refresh versions - Problem: Switching instances didn't reload version list - Fix: Added $effect hook in GameState to watch activeInstanceId changes - Impact: Version list auto-refreshes on instance switch ## Bug Fixes - P1 (State Synchronization) ### 5. Backend: install_fabric doesn't update Instance.mod_loader - Problem: Instance.mod_loader field wasn't updated after installation - Fix: Added instance_state.update_instance() call - Impact: Instance metadata stays in sync ### 6. Backend: install_forge doesn't update Instance.mod_loader - Problem: Instance.mod_loader field wasn't updated after installation - Fix: Added instance_state.update_instance() call - Impact: Instance metadata stays in sync ### 7. Backend: delete_version doesn't clean up Instance state - Problem: Deleting version didn't clear Instance.version_id or .mod_loader - Fix: Added cleanup logic to clear stale references - Impact: Instance state remains valid after deletion ## Testing - Added comprehensive integration tests in instance_isolation_tests.rs - Tests document 10 key scenarios for multi-instance isolation - All code compiles cleanly with no errors 2026-01-18T04:20:42Z HsiangNianian i@jyunko.cn 2026-01-18T04:20:42Z urn:sha1:373fb81604451f085bf9fbccf9251acb17e400a9 Update parse_java_version() to properly handle: - Build metadata (strip '+' and everything after) - Trailing garbage (strip '-' and everything after, e.g. -Ubuntu) - Underscore version separators (1.8.0_411 -> 1.8.0.411) This ensures Java versions are correctly parsed on all platforms: - Old format: 1.8.0_411 (Java 8 update 411) - New format: 21.0.3+13-Ubuntu (Java 21 with build metadata) - Short format: 17.0.1 (Java 17 update 1). 2026-01-18T04:19:43Z HsiangNianian i@jyunko.cn 2026-01-18T04:19:43Z urn:sha1:76086e65a7caf1bb8aa54a9404c70a714bc00da8 Add find_root_version() function to walk the inheritance chain and find the root vanilla Minecraft version from a modded version (Fabric/Forge). This is useful for determining which vanilla version's client.jar should be used when launching modded versions, as modded versions inherit from vanilla versions but don't contain their own client.jar. The function follows the inheritsFrom field recursively until reaching a version without a parent (the root vanilla version). 2026-01-18T04:19:00Z HsiangNianian i@jyunko.cn 2026-01-18T04:19:00Z urn:sha1:af7f8aec576b34d11bf136a75542822a74d7f335 Complete the rule_matches function to properly evaluate: - OS name (already working: osx/macos, linux, windows) - Architecture (arch field): match against env::consts::ARCH - OS version (version field): accept all versions for now (conservative) This ensures that architecture-specific libraries (e.g. natives-arm64) are correctly filtered based on the current platform. 2026-01-18T04:17:56Z HsiangNianian i@jyunko.cn 2026-01-18T04:17:56Z urn:sha1:e7d683d79bec482a13c821f8c1da3c8c1d719d1b Replace Ordering::Relaxed with appropriate synchronization: - Ordering::AcqRel for fetch_add operations that modify shared state - Ordering::Acquire for loads that depend on other thread's writes - Ordering::Release for stores that other threads may read This ensures visibility of downloaded bytes and completed files across concurrent download tasks without data races. 2026-01-18T04:16:55Z HsiangNianian i@jyunko.cn 2026-01-18T04:16:55Z urn:sha1:1021c921c5690ceb800c03140de0723f3338e121 Check if the Microsoft account token is expired before attempting to launch the game. If expired, attempt to refresh using the refresh_token. If refresh fails, return an error instructing the user to login again. Also removed #[allow(dead_code)] from is_token_expired since it's now actively used. 2026-01-18T04:16:05Z HsiangNianian i@jyunko.cn 2026-01-18T04:16:05Z urn:sha1:079ee0a6611499db68d1eb4894fab64739d5d2e7 Prevent race condition in duplicate_instance by copying the source game directory BEFORE creating and saving the new instance metadata. This ensures that if the copy fails, no orphaned metadata is created. Also copy the icon_path from source instance to maintain visual consistency.
