Warren	f90e4f496c	VFS/DataProvider/Config refactoring + SSH public key authentication ... Phase 1-6 of refactoring plan: - VFS abstraction (VfsBackend trait + LocalFs + OpenFlags builder) - DataProvider trait (SqliteProvider + PgProvider, SFTPGo-compatible) - Config refactoring (AppConfig unified sections, env overrides) - SSH handlers (sftp/scp/rsync) migrated to VFS + DataProvider - SSH public key authentication (Ed25519 signature verification) - SSH stderr → CHANNEL_EXTENDED_DATA support - Web auth uses DataProvider instead of direct SQL - User home directory from provider (per-user isolation) - PostgreSQL auth provider for SFTPGo compatibility	2026-06-18 23:35:18 +08:00
Warren	83fb0de78a	Fix 5MB SFTP download hang: batch process SFTP packets + WINDOW_ADJUST chaining ... Root cause: handle_channel_data processed only ONE SFTP packet per call, leaving remaining batched packets stuck in the buffer. Client waited for READ responses while server waited for more data — deadlock after ~3.1MB. Fix: - sftp_handler.rs: fix SSH_FXP_VERSION format (remove uint32 extension_count) - sftp_handler.rs: fix handle_open error mapping (.ok() → build_status_from_io_error) - channel.rs: batch-process ALL complete SFTP packets from buffer in loop - channel.rs: add pending_packets VecDeque for multi-response queuing - channel.rs: chain WINDOW_ADJUST + SFTP response when window is low - channel.rs: add adjust_remote_window() for client WINDOW_ADJUST - server.rs: drain pending_packets after each CHANNEL_DATA handler Verified: 5MB upload + download with matching MD5	2026-06-18 17:15:00 +08:00
Warren	5344a7c16e	Fix rsync: Use real rsync subprocess instead of in-process handler ... In-process RsyncHandler couldn't match openrsync protocol 29 flow after version exchange. Changed handle_rsync_exec() to use handle_interactive_exec() (spawning real rsync --server subprocess), same approach as SCP handler. All file sizes (5MB, 20MB, 50MB, 100MB) successfully transferred with MD5 verification passing. Transfer speed ~712 KB/s limited by AES-256-CTR encryption overhead.	2026-06-18 06:01:16 +08:00
