Four small, high-delight features that turn passive capture into glanceable signals.
- Sync chip on project cards: ahead/behind vs upstream + last-commit time, folded
into the existing concurrent per-repo metadata pass (git rev-list --count
--left-right @{u}...HEAD + git log -1 --format=%ct; no upstream → undefined, no route).
- Cost budget guard: COST_BUDGET_USD env (0 = off); a per-session one-shot latch
(Session.budgetNotified, cost is monotonic so never re-armed) fires a single push
on threshold crossing in manager.handleStatusLine; the already-broadcast telemetry
frame carries the warn (tg-cost-warn styling derived from costUsd>=budget via
/config/ui — no new ServerMessage). web-push title added to sw-push.js.
- "While you were away" digest: GET /digest?since= → {finished, needsInput, stuck,
totalCostUsd, sessions[]} aggregate over manager.list(); FE banner on reconnect.
- Recent commits per project: src/http/git-log.ts (NUL-delimited git log → CommitInfo[]),
GET /projects/log?path= (isValidGitDir), textContent-inert render in project detail.
All git via execFile (no shell) + validated cwd; new routes read-only; commit
messages rendered via textContent. Verified: typecheck + build:web clean, 1904 pass
at --test-timeout=30000 (two default-5s failures are slow-sandbox real-subprocess
timeout flakes — the known ring-buffer test + a new real-git-clone sync test — not
logic regressions).
A shared PTY can only be one size; min-sizing clamped the shared session to the
SMALLEST viewer, so a wide desktop got letterboxed when an iPad was also attached
(iPad looked full-screen, desktop did not).
Switch to latest-writer-wins: the device that most recently fit/focused drives the
PTY size, so whichever device you're actively using is full-screen.
- session.ts: setClientDims resizes the PTY directly (drop min across clients);
attach/detach/blur never resize (the active device keeps its size)
- frontend: TerminalSession.refit() force-resends dims; window 'focus' /
visibilitychange re-assert the active tab's size, so switching devices reclaims
full-screen
- tests updated for latest-wins (incl. join/hidden/blur don't resize)
Verified (two ws clients): 200x50 → iPad 100x40 → desktop refit 200x50 → iPad blur
keeps 200x50. 225 tests green.
The mirror looked broken because a backgrounded tab on one device still pinned
the shared PTY to its (default 80x24) size — so the device actively viewing got
a cramped terminal.
Fix: only an ACTIVELY-VIEWING client votes on PTY size.
- attachWs no longer seeds a default size vote (a join may be a hidden mirror)
- new 'blur' client message + clearClientDims(): a tab going hidden withdraws its
size vote (still mirrors output); show() re-casts it
- PTY size = min cols/rows across clients that have actually reported dims
- session/protocol tests cover hidden-mirror-doesn't-clamp + blur
Session manager (separate page, for the 'too many sessions' problem):
- GET stays; add DELETE /live-sessions/:id and DELETE /live-sessions[?detached=1]
- manager.killById(); LiveSessionInfo gains cols/rows
- public/manage.html + manage.ts: list/open/kill sessions, kill-all / kill-detached,
auto-refresh; 🗂 toolbar button; bundled as a 2nd esbuild entry
Verified: two concurrent clients mirror output + shared input; manage page
lists/kills (3→2→0). 225 tests green, tsc clean.
Relax the one-WS-per-session invariant (#5) so multiple devices mirror the
same live terminal (everyone sees output, anyone can type — tmux-style).
- types.ts: Session.attachedWs → clients Set + clientDims Map; add cwd;
SessionManager.list() + LiveSessionInfo
- session.ts: broadcast() output/exit to all clients; attachWs JOINS (no kick,
takes dims); detachWs removes one client, stamps detachedAt only when the last
leaves; setClientDims resizes PTY to the MIN cols/rows across clients
- manager.ts: join instead of kick; broadcast status; onExit drops only when a
client was attached; list() for discovery
- server.ts: GET /live-sessions; resize → per-client setClientDims; close →
detach one client; permission gate uses clients.size
- tests: rewrote session/manager tests for multi-client (join/broadcast/min-dims/
last-detach) + list(); 222 pass, tsc clean
- src/session/tmux.ts: sync tmux CLI wrappers (available/has/kill), best-effort
- config: useTmux from USE_TMUX env (1/0/auto→detect tmux on PATH)
- session: when useTmux, spawn 'tmux new-session -A -s web_<id> <shell>' (the
node-pty proc is a tmux CLIENT); createSession takes an optional id for
re-attach; Session.tmuxName; kill() runs tmux kill-session
- manager: handleAttach re-attaches to a surviving 'web_<id>' tmux session after
a restart (Case 3.5); shutdown kills only the client pty for tmux sessions so
the shell keeps running
- tests: USE_TMUX:0 in shared integration cfg (no tmux leakage); unit CFGs
useTmux:false; integration 'H1' (real tmux): set var → restart server →
re-attach → var survived. 208 tests green.
