Add restart controls for servers and groups, move tool labels into a dialog - #130
Conversation
…dialog
Restarting a server meant editing it or stopping and starting it by hand,
even though the common reason to want one — an upstream that has grown new
tools since it launched — needs nothing but a fresh activation.
Backend: `Supervisor.restart` is the single restart primitive (stop the
unit under the unit lock, queue a fresh activation, no registry write, so
config_hash and updated_at are untouched). `POST /api/servers/{id}/restart`
exposes it with the same ownership re-check `retry` uses, and refuses a
disabled server with a 409. `POST /api/groups/{name}/restart` resolves the
group through the registry (wildcard included) and calls the same primitive
per enabled member, reporting which were restarted and which were skipped.
Frontend: one `RestartButton` (server or group target, button or menu-item
skin) renders on the server page header, in the dashboard card's menu, and
on each group row. Start/stop/retry moved into a shared
`ServerActionButton` for the same reason — the card, the page header, and
the new group member rows had no business each owning a copy. Both expose a
bindable `busy` so a page can gate its own work on the op it started.
Settings → Groups now lists each group's members with their own state,
start/stop/retry, and restart, so a single member can be bounced without
leaving the page.
Tool labels are edited in one dialog (`ToolLabelModal`) instead of a form
that expanded inside the tool row: the row clamps long descriptions and
only opens the dialog, which holds a local draft until Save stages it. The
staged batch's Apply bar now floats above the page, so a change made at the
top of a long tool list can be applied without scrolling back to it.

… focus Four findings from the automated review, all real: - A group restart holds the request open across one process teardown per member, so `require_admin` at entry is not enough: pass an authorization hook per member that re-reads committed admin state at both of `Supervisor.restart`'s decision points, the way the per-server route already did. A demotion mid-loop now stops the remaining members. - `_visible_now` answered only "can this principal still see it", so a disable committing while the stop awaited teardown was followed by a fresh activation the endpoint had promised not to queue. It now reports `(visible, enabled)` from the same single query, and the restart hook refuses with a 409 — the stop stands, since that is the desired state the disable just wrote. - Settings has no status polling, and a group restart answers with ids rather than summaries, so every member row kept showing its pre-restart state until a reload. Re-read the server list when the group restart returns. - ToolLabelModal declared `aria-modal` but trapped nothing: Tab past Save reached the lifecycle and tool controls underneath. It is a native `<dialog>` opened with `showModal()` now, so the browser owns the focus trap, the inert background, Escape, and returning focus to the opener; every dismissal path funnels through the dialog's own close event. jsdom implements none of that, so test-setup gains a minimal shim alongside the existing matchMedia/ResizeObserver gap-fills.

🩺 Stability & Availability | 🟠 Major | 🏗️ Heavy lift
Batch wildcard restarts without serializing teardown. restart_group resolves "*" to every registered server and awaits sup.restart for each member. Each call holds Supervisor._unit_lock while ServerUnit.stop() waits for process termination and Docker cleanup, so 50 running members can keep the request and reconciler blocked for many minutes. Do not wrap the current calls in a semaphore because _unit_lock still serializes them. Add a Supervisor batch-restart operation that preserves the lock, performs independent teardowns concurrently, queues activations, and returns GroupRestart only after the listed members are actually bounced. A background task would violate the current response contract and docstring unless that contract changes.

Split answer, since this thread carries two findings.
Per-member failure containment — fixed in 1532409. You're right that a teardown exception took the whole batch down after earlier members were already stopped and queued, with no report of which. Each member's restart is now contained and the failure lands in a failed list of its own — not skipped, which keeps its meaning of "had nothing to bounce". Only the caller losing admin still stops the batch. Covered by test_group_restart_reports_a_member_whose_teardown_fails.
Concurrent teardown — not in this PR. Serialization isn't specific to restart_group: _unit_lock is the supervisor's invariant for every unit mutation, and the reconciler's own convergence stops units one at a time under the same lock. A group restart of N members costs exactly what N per-server restarts cost. Making teardowns concurrent means changing that invariant — port allocation, docker container reaping, and interleaving with a reconcile pass all assume one unit mutation at a time — which is a supervisor-wide change with its own risk profile, not something to land inside a UI PR. The cost is documented in the endpoint docstring and the README instead, so the behavior isn't a surprise.

@pacnpal, verified. The current restart_group implementation contains per-member teardown failures in failed and continues with later members. It preserves skipped for disabled members. This resolves the failure-containment finding.
The _unit_lock invariant makes concurrent teardown a supervisor-wide change. I agree that it should not block this PR. Would you like me to create a follow-up GitHub issue for concurrent group restart design and throughput?

Learning: In `backend/app/supervisor/supervisor.py`, `Supervisor._unit_lock` serializes every unit mutation, including reconciler convergence. Concurrent group-member teardown would require a supervisor-wide concurrency design that preserves port allocation, Docker container cleanup, and reconciliation invariants.

CodeRabbit's review of the first commit repeated three findings already fixed in d01e703 (group re-authorization, the modal focus trap, stale member rows). Two were new: - A teardown that raises took the whole batch down: the members already bounced were stopped and queued, but the endpoint 500'd without saying which. Each member's restart is now contained, with the failure reported in a `failed` list of its own — not `skipped`, which means a member that had nothing to bounce. Only the caller losing admin still stops the batch. - The per-member hook now re-reads the member's own row too, not just admin state, so a disable committing while the batch runs leaves that member stopped (its new desired state) and reported as skipped rather than restarted — matching the guarantee the per-server route already makes. The group restart's toast reports failures, since ids are all a group answers with. Not taken: CodeRabbit also proposed a supervisor batch-restart primitive that tears members down concurrently. Serialization is the supervisor's existing invariant — every unit mutation, the reconciler's own stops included, takes the unit lock — so concurrent teardown is a supervisor-wide change (port allocation, docker reaping, reconcile interleaving) and belongs in its own PR rather than riding along with this UI work. The cost is documented instead. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_014H1G6LjeY3ckBtZhVNAd6t

…ervers Two more from Codex, both real: - The Cancel button called the caller's `onclose` directly instead of `dismiss()`, so it unmounted an open dialog without `close()` — skipping the browser's focus restoration that the close icon, Escape, and the backdrop all get. Every dismissal now takes the same exit, and the tests assert the dialog is actually closed on Cancel and on Save. - A delete cancels the activation request and then waits for the unit lock to stop the process, so a restart holding that lock could queue a fresh request in the wait — after the cancel, before the row was removed. Reconcile only consumes a request while iterating servers that exist, so that id sat in the map forever. Restart now queues inside the lock, and the reconcile sweep drops any queued activation whose server has no row at all — self-healing, rather than depending on every caller's cancel ordering (the same leak was reachable through `retry`).

Codex, on the restart path: a restart frees the very slot it means to reuse. The reconcile start loop walks enabled rows in created_at order and starts every unitless one, so at `max_running` an older row that had been starved (it hit the limit on an earlier pass) claims that slot first — and the server the operator just restarted comes back `max_running reached`, after an endpoint that reported it starting. The loop now visits servers with a queued activation first. A wake, a start, and a retry have the same claim as a restart: someone asked for THIS server now, where a starved row is only waiting for capacity that reconcile retries every pass anyway. The sort is stable, so everything else keeps its created_at order. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_014H1G6LjeY3ckBtZhVNAd6t

Three more from Codex, all real: - The dialog was rendered from a row re-derived out of live discovery, so a background poll that answered with an empty tool list during someone else's restart dropped the row, unmounted the dialog, and took the operator's unsaved typing with it. The open tool is a snapshot taken when the dialog opens now; nothing re-derives it while it is open. - Enter in the name field saved unconditionally, so for an IME it committed the candidate being composed AND the dialog — staging a half-typed name. Both shortcuts now ignore a composing Enter. - Settings had no poll, and a lifecycle action answers as soon as desired state is written, so a member's pill sat at `starting`/`stopping` until a reload. The member rows now follow a transition until it settles, on the same `shouldPollFast` predicate the dashboard polls on, and then stop — the rest of the page is configuration, not a status view.

Two P1 races from Codex, both real: - `_stop` popped the unit before awaiting its teardown, so a stop that RAISED left a possibly-live process with no unit registered — and the next reconcile, seeing "no unit" for a still-desired server, would launch a second copy beside it. The unit goes back in the map on failure; the next pass retries the stop. - A delete's stop runs while the row still exists, so a reconcile pass could consume a queued activation (an operator restart) in that gap and relaunch the server before the delete committed — leaving it running until the next sweep. The delete now cancels and stops again once the row is gone; both are no-ops in the common case. And three smaller ones (CodeRabbit and Codex, overlapping): - Settings could poll forever from an abandoned page: clearing the timer on teardown doesn't stop a refresh already in flight, whose `finally` schedules the next tick afterwards. A liveness flag stops the chain. - The dialog lost its accessible name in the native-<dialog> conversion — the heading was there but nothing pointed at it. - A group restart where every member's teardown failed reported "No enabled members were restarted", which reads as an empty group. Zero-restarted now says which of the two it was. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_014H1G6LjeY3ckBtZhVNAd6t

CodeRabbit's outside-diff note on the last review, and a real gap: a disconnect restarts the server, but its guard checked only `oauthBusy` and `applyingTools`, and the lifecycle buttons never checked `oauthBusy`. So a disconnect could overlap a stop, a restart, or a tool Apply — every one of which bounces the same bridge. The gate now runs both ways: `doDisconnect` refuses while a lifecycle op or an apply is in flight, the action and restart buttons refuse while an OAuth call is, and `toolEditsBlocked` counts it too. `oauthBusy` moves up to the other lifecycle flags, since the interlock derives from it.

Retaining a unit whose stop() raised kept a possibly-live process accounted for, but a retained unit is invisible to the sweep: an enabled server with an unchanged config_hash and a "stopping" unit matches no re-derive branch, so it sat there unreachable until an operator acted by hand. Mark those ids in _teardown_failed, retry the stop from the sweep, and start only once it succeeds. Every stop reconcile performs now goes through _stop_quietly, so one wedged unit reports its failure on its own row instead of abandoning the pass for every server after it — and a failed quiesce is not recorded as idle, which the proxy would treat as wakeable. Delete runs its final teardown in a try/finally. The row is gone by then, so a raise there can't be retried through the endpoint (a second DELETE 404s at the lookup) and would strand the OAuth credential file and leave the deleted server mounted in its groups; the supervisor still converges the process itself. Settings starts following member transitions from the initial load too, not only from a lifecycle action taken on the page, so a member that was already starting when the page opened doesn't show a frozen pill until a reload.

A failing stop is often instant (a missing docker binary, a refused socket), and unit.stop() sets "stopping" before it raises — that state notification nudges the supervisor, so run_forever skips its interval wait and lands straight in an identical attempt. Retrying a quarantined unit every sweep therefore spun, hammering the very daemon that was already failing. _stop now records when a quarantined unit may next be retried, doubling the delay per failure to a 60s cap, and _stop_quietly (the sweep's only stop) skips an attempt until then. An operator's own stop or restart goes through _stop and is never throttled.

Retrying a failed teardown gave two paths a way to persist observed state that isn't true. A DELETED server reaches the undesired-stop loop only through a quarantine, and its runtime row went with the delete — writing "stopped" once the retry succeeds resurrected an orphan row nothing reads and (foreign keys being off) nothing cleans up. And the disabled-row cleanup runs off a snapshot taken before the stop attempt, so a disabled server whose teardown failed was recorded as stopped while its unit stayed registered and its process possibly alive; a unit still in the map now skips that write, and the retry persists the truth once the stop succeeds. Settings drops a member poll superseded while it was in flight. A list read that started before a Stop returned carries the pre-action row, so landing it put running + Stop back over the newer stopping — and with nothing transitional left the follow stopped there, stranding the page until a reload.

Delete only waited on a tool Apply. The one that bites is an OAuth disconnect: it stops the bridge, clears the token store and re-activates, all re-reading the row — so a delete landing mid-flight turns the disconnect into a 404 nobody asked for. A start/stop, a restart and a clone are the same shape. One deleteBlocked predicate now gates doDelete and both Delete buttons, matching how toolEditsBlocked already gates the tool batch. The settings poll guard also needed a sequence, not just a revision: two list reads can be in flight at once (a group restart's refresh and a poll tick), and the slower one landing last installed the older snapshot — then stopped the follow if nothing in it was transitional. Only the newest read applies. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_014H1G6LjeY3ckBtZhVNAd6t
An enabled server whose unit is mid-stop renders as a queued restart, and a quarantined unit looks exactly the same — except its teardown keeps failing and the supervisor is retrying it on a backoff. The summary hid that behind the blank startup shape, so the operator watched a spinner that never resolved and never explained itself. Supervisor.teardown_error names the failure for an id under quarantine, and the live summary carries it on the queued-restart path.

last_error alone stayed invisible: while a startup is active the card and the detail page both hide it and render the startup status message instead, so a quarantined server still showed a bare, endless Queued. The reason now rides in the queued status's message as well, which is the line an operator sees.

Restarting a server meant editing it, or stopping and starting it by hand — even though the common reason to want one (an upstream that has grown new tools since it launched) needs nothing but a fresh activation.
Restart
Backend.
Supervisor.restartis the single restart primitive: stop the unit under the unit lock, queue a fresh activation, write nothing to the registry — soconfig_hashandupdated_atare untouched and a restart never reads as an edit. Unlikeretryit carries no state precondition, so it works fromrunning,idle(the quiescence marker is cleared),starting, andfailed.POST /api/servers/{id}/restart— an authorization hook re-reads the committed row at both of the supervisor's decision points, so neither an ownership reassignment nor a disable landing during teardown can be followed by an activation this endpoint promised not to queue. A disabled server is a 409 (Start is its action).POST /api/groups/{name}/restart— resolves members through the registry (wildcard included) and calls the same primitive per enabled member, returning{name, restarted, skipped, failed}. Each member carries its own hook: a demotion mid-batch stops it with a 403, a member disabled mid-batch is left stopped and reported asskipped, and a member whose teardown raises is reported infailedwhile the rest of the batch continues. A group hosts no process of its own, so restarting one is exactly "restart each member"; the hub is deliberately not resynced, since the post-reconcile hook remounts each member as it comes back. Members are bounced one at a time —_unit_lockis the supervisor's invariant for every unit mutation, the reconciler's own stops included — so a large group's restart costs the sum of its members' shutdowns.Two ordering rules keep a restart honest against the reconciler: the activation is queued inside the unit lock and the sweep forgets requests for ids with no row (so a restart racing a delete can't leave a queued activation behind), and requested activations are started before starved rows (so a restart doesn't hand the slot it just freed to an older server waiting on
max_running).Frontend. One
RestartButton(server or group target, standalone-button or kebab-menu-item skin) renders on the server page header, in the dashboard card's ⋯ menu, and on each group row in Settings.Teardown that fails
A restart is a stop followed by a start, which raised the question of what a stop that raises should mean.
_stopused to pop the unit before awaiting teardown, so a failure read to the next sweep as "no unit for a desired server" and could launch a second copy beside a process that may still be alive. Now:config_hashand astoppingunit matches no re-derive branch), so_teardown_failedis what makes the sweep retry the stop, and start only once it succeeds.unit.stop()setsstoppingbefore it fails, and that state notification nudges the loop past its interval wait, so an unthrottled retry spun against the very daemon that was already failing. An operator's own Stop or Restart goes through_stopand is never throttled._stop_quietly, so one wedged unit reports on its own row instead of abandoning the pass for every server after it. A failed quiesce is not recorded asidle(which the proxy treats as wakeable), a deleted server's retry writes no orphan runtime row, and a disabled server whose teardown failed is not recorded asstopped.Supervisor.teardown_errornames it, and the live summary carries it in bothlast_errorand the queuedstartup_status.message— the latter being the line the card and detail page actually render while a startup is active.DELETE /api/servers/{id}runs its final teardown in atry/finally. The row is gone by then, so a raise there can't be retried through the endpoint (a second DELETE 404s at its lookup) and would strand the OAuth credential file and leave the deleted server mounted in its groups.Individual controls for group members
Settings → Groups now lists each group's members with their own state pill, start/stop/retry, and restart, so one misbehaving server in a bundle can be bounced without leaving the page. Membership is resolved the way the backend resolves it (wildcard = every registered server), and the rows re-read the server list when a group restart returns, since a group answers with ids rather than summaries and this page has no polling of its own.
To keep that honest, start/stop/retry moved into a shared
ServerActionButton— the card, the page header, and the new member rows had no business each owning a copy of "which action, which endpoint". Both shared buttons expose a bindablebusyso a page can gate its own work (tool Apply, clone, status poll) on the op it started.Member transitions are followed from the initial page load too, and a list read that has been superseded — by a lifecycle action, or by a later read that already landed — is dropped rather than allowed to reinstall an older snapshot and stop the follow on it. Delete now waits behind one
deleteBlockedpredicate covering every other op in flight; the one that bites is an OAuth disconnect, which re-reads the row throughout and would 404 mid-flight.Tool label editing
Editing a tool's name or description opened a form inside the tool row, below the description it was editing — so on a server with wordy upstream tools you scrolled past a wall of prose to reach the fields. Now:
ToolLabelModalis the one editor: a native<dialog>opened withshowModal(), so the browser owns the focus trap, the inert background, Escape, and returning focus to the opening button. Every dismissal — Save, Cancel, the close icon, Escape, the backdrop — funnels through the dialog's owncloseevent. It holds a local draft that Save stages into the page's batch, and warns about a rename onto a name another exposed tool already holds.Testing
backend: 1099 passed — restart bouncing a live unit without touching config, waking an idle server, refusing a disabled one, refusing when a disable lands during teardown, 404 on unknown; group restart over explicit and wildcard membership, stopping on a demotion mid-batch, skipping a member disabled mid-batch, and reporting one whose teardown fails; the reconcile invariants above; and the teardown-failure set — a quarantined stop retried and then started, the sweep continuing past a wedged unit, the retry backoff (including that an operator action bypasses it), no orphan runtime row for a deleted server, no falsestoppedfor a disabled one, delete cleanup after a failed final stop, and the failure surfacing in the summary.frontend: 141 passed (npm run test),npm run checkclean,npm run buildclean — new suites forRestartButton,ServerActionButton, andToolLabelModal.test-setup.tsgains a minimal<dialog>shim: jsdom implements none of its modal behavior.Every new test was verified failing against the code it guards.
