The supervisor stops — and clears every MachineLink with it — as soon as no open workspace is on a remote machine, which closing the last remote window does. The connection itself stays: a closed window is a detach, so HostLinks keeps the socket for whatever opens next. Reopening that workspace then found a live connection with no link behind it. `reopen_remote_at_startup` read the surviving HostLinks entry as "another window got there first" and returned before starting the pump, so nothing ever put a MachineLink back and `status_of` answered Disconnected for good: a "Not connected to <machine>" strip and a dead keyboard over panes that were visibly still running on the far side. An existing HostLinks entry is not a reason to skip the supervisor. It answers "is there a socket"; what the window renders from is `machines`. Both now go through RemoteLinks::supervise, which is a no-op for a local workspace and an unconditional ensure_running for a remote one — idempotent, so a machine already supervised costs a flag check, and the first tick over a live socket marks it Attached without opening a second SSH session. Fixes the same hole on the switcher's path, which never told the supervisor anything at all: picking a remote workspace from it goes through `switch_workspace`, not the launch path.
tty7
A terminal workbench: shells, sessions, SSH, coding agents.
Pure Rust · GPU rendering on Zed's gpui · VT core from Alacritty
English · 简体中文
Why
- Fast — ~2× the throughput of Alacritty, Ghostty, or Kitty (benchmarks)
- Sessions persist — quit or reboot; your shells keep running, no tmux
- Editor-grade input — completion, syntax highlighting, history search built in; zero config for zsh, bash, fish, PowerShell
- Agent-aware — recognizes Claude Code & co. in a pane: status, notifications, session resume
