run_stream polled pane.controls(epoch) every 200ms behind a read timeout, so every attached pane woke its thread five times a second just to notice a handover that may never come. The writer already learns of the handover the instant it happens — its channel closes — so it now shuts the connection's read side down on its way out, and the reader goes back to a plain blocking read. SshManager::routes() reported a link as disconnected whenever its slot's try_lock failed, which is precisely when the link is in use. The CLI's -m <machine> refuses to route over a link it is told is down, so an actively used connection would intermittently fail. Busy now reads as connected, matching how SshConnection::is_alive resolves the same contention. Also: the exit-code probe takes the child lock with try_lock, since Drop holds it across a blocking wait(), and its window drops from 2s to 500ms — it only needs to cover the race between pty EOF and the child becoming reapable, and everything past that is a pane that looks frozen to every client. Observer budget now covers status traffic and the initial replay, not just output. Uptime is anchored where the control listener opens so a GUI-hosted server does not report itself as freshly started.
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
