The nightly channel has been frozen since 06:32 on 2026-08-10: every run dies in bundle-macos.sh with "hdiutil: create failed - No space left on device", on macos-15-intel, after the build, the signing and the notarization have all succeeded. The host disk was never full. #476 read that message as the runner running out of room and freed space for it; the `df -h` it added to prove the point disproved it instead — 105 GiB available, and the run failed anyway. The path in the error is under /Volumes/tty7, which is the image being created, not the runner: the volume ran out, not the disk. `hdiutil create -srcfolder` sizes the image from the bytes it is about to copy and does not cover what the filesystem spends carrying them, so a bundle that fits by measurement still runs the volume dry partway through the copy. It is a threshold rather than a cliff, which is why this began without anyone touching packaging: the binaries grew over edfadb7..fafcaa0, the x86_64 pair is the larger one and crossed it first, and arm64 kept building fine just underneath. Ask for the room explicitly — twice the content plus 64 MiB. The image is compressed on the way out, so the slack is nearly free: on a stage of this shape, 127 MiB of empty volume cost 672 KiB in the published DMG. Also drop #476's deletion of the build tree. It was paying for a problem that did not exist, and the bill was rust-cache finding nothing to save and every macOS build recompiling the dependency graph. The `mv` from that commit stays: a second full copy of the bundle is genuinely redundant, and nothing reads dist/tty7.app after this point. Verified locally against a staged bundle of the real shape (73 MiB, 101 files): the image is created, mounts with every file present, and detaches clean. The remaining unknown is only whether CI agrees, which the next nightly answers. 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
