* fix(daemon): respawn on PTY write dropped to a dead daemon socket (STA-2373) DaemonPtyAdapter.write() sends keystrokes via fire-and-forget client.notify(). When the daemon dies (retirement, crash, kill), the socket disconnects and the notify is silently dropped — no rejection reaches withDaemonRetry, so the dead-endpoint respawn never fires and the attached pane freezes. Only a request/reply RPC (e.g. createOrAttach from opening a new terminal) detected the death and forked a replacement. DaemonClient.notify() now reports delivery; a dropped write to a still-active session drives the shared respawn coalescer directly (reconnecting the permanent client before releasing the temporary adoption lease, mirroring withDaemonRetry's ordering), so the pane self-heals like the createOrAttach path. Cross-platform + SSH-safe: no platform assumptions, pure adapter logic. Complements (does not duplicate) #8426, which fixes the adjacent in-daemon bug where a thrown node-pty write no longer marks the handle dead. That is daemon-side; this is the app-side dropped-notify that never triggered respawn. * fix(daemon): restore adapter state after dropped-write respawn * fix(daemon): recover writes after endpoint respawn * fix(terminal): remount panes after daemon death * fix(daemon): recover sibling panes after daemon death, not just the written one When a daemon dies, its dropped-write respawn only remounted the pane whose write detected the dead endpoint. Sibling panes (alive at death but not typed into) were left frozen: stale prompt pixels, silently-dropped input, no live child, and no recovery even on later keystrokes — the exact STA-2373 frozen-typing symptom on non-triggering panes. DaemonPtyAdapter now fans a write-unavailable signal out to every active session when it recovers from a dead endpoint, emitted while the sessions are still in activeSessionIds so the renderer's liveness gate still reads them live. pty.ts forwards each to the existing pty:writeUnavailable channel, so all panes remount + re-attach through the same path the written pane already used. Adds a revert-sensitive regression test: with two sessions and only one written after the daemon dies, the sibling must also be signaled to recover. * revert(format): drop repo-wide oxfmt churn unrelated to STA-2373 A review pass ran `oxfmt --write .` across the tree, pulling seven files with no bearing on the dead-daemon respawn fix into the PR diff. Restored to origin/main byte-for-byte so the diff carries only the respawn change. * fix(daemon): snapshot active sessions before the write-unavailable fan-out A listener that kills a pane mutates activeSessionIds mid-iteration, which can skip the very sibling the fan-out exists to reach. Matches the snapshot fanoutSyntheticExits already takes. * fix(daemon): re-arm dead-endpoint recovery on every daemon death The respawn-storm latch was only released once every awaiting session rebound. Background sessions have no mounted pane, so nothing ever calls createOrAttach for them and they hold the awaiting set non-empty forever — latching the fan-out off after the first death and silently making the whole fix one-shot. Re-arm on the disconnect event instead, which fires once per established connection, so the storm guard still holds within a single incident. * fix(daemon): route the write-unavailable fan-out through the pty router Main subscribes on the routed provider, and DaemonPtyRouter is the live localProvider whenever a legacy daemon socket exists — the common case when an in-place update bumps PROTOCOL_VERSION with terminals running. It forwarded write but not onWriteUnavailable, so the fan-out reached no listener and only the written pane recovered: STA-2373 unfixed, silently. Also stop rejecting writes on adapters that cannot respawn. Legacy adapters have no respawn, so the remount reattaches to nothing and rebuilds the pane empty, losing scrollback the user could still read — worse than the pre-existing silent drop. And guard the renderer's write-unavailable handler on ptyId like its sibling data/replay handlers, so a transport that rebinds without detaching cannot remount a healthy pane. * fix(daemon): route the write-unavailable fan-out through the degraded provider DegradedDaemonPtyProvider is the live localProvider in degraded launch mode and main subscribes on it, but it forwarded onData/onExit/onReplay/ onBackgroundStreamEvent and not onWriteUnavailable — so the fan-out reached no listener and siblings stayed frozen. Same defect as the router, one provider over. The file sat at its max-lines ceiling, so make room by reusing one combineUnsubscribes helper across the three places that already repeated that loop rather than bumping the limit. Forward to the daemon adapters only: the local fallback has no dead-socket problem. * refactor(daemon): share the listener-fanout unsubscribe combination Adding onWriteUnavailable to both provider wrappers left each file at exactly 300/300 lines, so the next line anyone added would have broken max-lines with no sanctioned escape hatch. Both already repeated the same combine-unsubscribes loop, so lift it into one module: duplication drops and each file gets its headroom back. * fix(test): stop the fake emitter colliding with the private adapter emitter DaemonPtyAdapter.emitWriteUnavailable is private, so declaring a public member of the same name on a mock intersected with DaemonPtyAdapter collapsed the whole type to never — one collision produced 54 typecheck errors, taking out pre-existing assertions in both files too. Rename the fake to triggerWriteUnavailable and declare onWriteUnavailable on ProviderMock, which IPtyProvider does not carry on this branch. vitest does not typecheck, which is why a red build sat behind a green suite. |
