* fix(remote): stop the server on machines that have no /proc, and show the install on the strip Restarting the remote server timed out after ten seconds on every Mac and BSD, with the old daemon still running and the new binary already sitting next to it, unlaunched. Both the probe that finds the running `tty7-server-*` and the command that terminates it walked `/proc/[0-9]*` and read each `exe` symlink. There is no `/proc` there. Two things then went wrong at once. zsh is the login shell on macOS, and it aborts the whole command line when a glob matches nothing, so even the trailing `true` never ran; and `cycle_daemon` discards the result of the terminate, so a command that killed nothing was indistinguishable from one that worked. `daemon_is_serving` then answered yes until the deadline. Guard the glob behind `[ -d /proc ]` — unreached, it is never expanded, so zsh has nothing to abort on — and fall back to `ps`, whose `comm` is the full path on the BSDs. It cannot be the only branch: Linux truncates `comm` to 15 characters, one short of `tty7-server-c7p5`, which is why `/proc` stays the first choice where it exists. `check_running_build` reads the same probe and was equally blind on those machines; it can see now. Separately, the install progress bar only ever existed inside the switcher. Pressing Update Server from a parked workspace with no switcher open froze the window for the length of the download and then produced a modal, with nothing in between. The strip draws it too now — caption and bar from the same source the switcher uses, and no button while an install is in flight, since pressing it again would start a second one on top of the first. * fix(remote): say why a stop failed, and stop a leaked install from eating the strip's button Three things the no-/proc fix left standing. `cycle_daemon` still discarded the terminate's result, which is the other half of why a Mac cost a bug report: the command ends in `true`, so anything short of success means the far end never reached the kill at all, and that is exactly what a zsh abort looks like. It is now logged, and named in the timeout error — "the running remote daemon did not stop within 10s" on its own blames a daemon for ignoring a request nobody managed to send it. The strip hides its Update Server button whenever an install is in flight, which is right, but it reads the progress registry with no link state to temper it — unlike the switcher. `finish_connect` bows out before clearing that entry whenever `connect` has moved on in the meantime, and a switcher disconnect or a move to another workspace both do that mid-install. The leftover froze a progress bar on every window pointed at the machine and took away the one button that could have fixed it. Cleared where the attempt actually ends instead, however it ended. The switcher kept its own copy of the progress bar after the caption was shared; it draws the shared one now. Tests: the probe runs for real in every shell on the machine rather than only parsing under `sh -n` — the glob that started this was valid syntax and only fell over when zsh ran it, which no `-n` can see. `ps` is checked on its own where the fallback would actually be taken, since that arm eats its own stderr and a rejected flag would otherwise cost nothing visible. And a stop that fails is asserted to reach the error. `with_shutdown_timeout` exists so that last test does not sit out ten seconds. --------- Co-authored-by: l0ng-ai <24760907+l0ng-ai@users.noreply.github.com>
tty7
A terminal workbench: persistent sessions, remote work, agents.
Pure Rust · GPU rendering on Zed's gpui · VT core from Alacritty
English · 简体中文
Why
- Performance — ~2× the throughput of Alacritty, Ghostty, or Kitty (benchmarks)
- Persistent sessions — quit or reboot; your shells and supported agent sessions keep running, no tmux
- Editor-grade input — suggestions, completion, highlighting, history search
- Remote development — files, repos, panes, and git data stay on the remote machine
- Native SSH — profiles, SFTP, port forwarding, and jump hosts
- Agent-aware — Claude Code, Codex & co.: status, notifications, git context
- CLI + Skills — agents create panes, run commands, and inspect output
