fix(ui): preserve reorders across in-flight polls by snowyukitty · Pull Request #683 · wainmann/agent-manager

snowyukitty · 2026-10-02T01:16:41Z

What changed

Keep local session and group reorders visible while an older store listing is in flight. Reconcile only locally swapped siblings, preserve fresh row fields and unrelated managers' ordering, and retire the reorder mark when a fresh listing arrives. Older listings still deliver notification focus, queued messages and pane data.

Closes #444. A stale poll could repaint the pre-swap list after a successful Shift+Down, so the next move chose the former neighbor and swapped backward.

Scope

The existing UI already uses listedAt to reconcile launches and removals. This applies that boundary to session and group ordering and guards listing-derived state against out-of-order delivery. It adds no action, setting, provider-specific rule or platform branch.

This follow-up incorporates main through 154b074 and keeps group bases inside the fresh-listing guard. The upstream archive/kill-after-turn handling stays outside that guard, alongside per-pass data, so an older listing can deliver a completed turn without replacing fresh rows or ordering. A real managed-session regression verifies this integration; removing the after-turn call makes that regression fail.

Validation

Fresh isolated Linux checks used Go 1.27.1 and tmux 3.3a, a throwaway HOME and short dedicated socket directory, with TMUX unset:

Focused reorder and stale-listing tests with go test -race -count=3 ./internal/ui: passed.
Full go test -race -p 1 -timeout 20m ./...: passed across all packages at b3a9087. After the theme-only upstream advance to 154b074, the four PR files and cumulative patch remain byte-identical. On 154b074, the full systheme race suite and focused UI races were rerun with -count=3, along with vet/build/format, live TUI and the regression failure control. The whole-repository suite was not rerun at 154b074. The first full run hit the default ten-minute UI-package limit; the successful run uses one package at a time and an explicit twenty-minute limit without excluding tests.
go vet ./..., go build ./..., and gofmt -l on the four changed Go files: passed.
Built and ran the merged TUI with three real managed bash terminal sessions. Two consecutive Shift+Down moves changed the painted order from [alpha bravo charlie] to [bravo alpha charlie] to [bravo charlie alpha]; it retained that order after a later poll. Frames were captured from the dedicated tmux socket.
git diff --check: passed.

The original stale-order and consumed-notification regressions were previously demonstrated failing on their corresponding unpatched heads. Current full native checks replace the earlier environment-limited suite evidence; they do not establish a full platform/provider matrix.

Provider agent CLIs, mouse drag, macOS, native Windows and SSH sessions were not exercised in this follow-up. Earlier live keyboard validation under WSL2 remains historical evidence. Completing the remaining matrix requires those real CLI, input and platform sessions; generic ordering is covered by the native race regressions above.

Summary by CodeRabbit

Bug Fixes
- Session and group ordering now remains consistent when background refreshes overlap with manual reordering.
- Older refresh results no longer overwrite newer session or group lists.
- Refreshes still deliver current notifications, focus information, and pane updates even when their session or group data is outdated.
- Newly arrived rows and refreshed session details are preserved while existing rows are reconciled.

📝 Walkthrough

Walkthrough

The UI tracks local session and group reorders across refreshes. Older listings do not replace session or group data or trigger focus-exit checks. Other refresh metadata continues to update for older listings.

Changes

Session and group order reconciliation

Layer / File(s)	Summary
Record local reorder state `internal/ui/keys.go`, `internal/ui/model.go`, `internal/ui/reorder_refresh.go`	The model stores pending reorder marks. Row swaps record the affected rows and their local order within a sibling set.
Reconcile incoming listings `internal/ui/model.go`, `internal/ui/reorder_refresh.go`, `internal/ui/reorder_refresh_test.go`	Refresh handling skips session and group updates for older listings. For accepted listings, it reconciles pending order while retaining incoming row data. Tests cover stale and fresh listings, new rows, refreshed values, and other refresh updates.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Bug fix · Severity of issue fixed: Medium

Merge Risk: ⚪ Minimal · up to 37e61

This change keeps local session and group reorders visible while an older listing is in flight, and it still delivers the other refresh updates. No actionable merge-blocking risk remains in the supplied evidence.

Security Architecture Review

Security architecture risk: ⚪ Minimal · up to 37e61

The change preserves local ordering without adding access, privileges, or production entrypoints. The inspected paths retain store-backed ownership and lifecycle checks, and no material security risk was identified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

inferred — The newly introduced mechanism changes the current manager's ordering and listing acceptance. Its local ordering authority is restricted to affected sibling identities; persistent reordering continues through the existing store operations, without a new privilege-bearing interface.

Trust Boundaries and Controls

observed — Manager ownership is determined in the poller through the store claim and session socket checks. The UI's socket and leading-manager fields produce an ownership label, not that claim. Their acceptance from older deliveries existed before this PR and is not a newly introduced authorization bypass.

Resilience and Maintainability Implications

observed — The freshness guard preserves current rows and group bases without dropping notification focus or terminal after-turn completion. Focus delivery checks for an available row and leaves an existing focused pane when switching sessions, avoiding disagreement between the selected row and keyboard target.

Full details: Visual Evidence

Explanation

The reorder change has a meaningful visual state: the session order shown in the UI. The PR description reports that tmux frames were captured and lists the order changes in text, but it does not include before/after screenshots or a recording. The changed code confirms that the PR updates and rebuilds the displayed row order.

Full details: No Speculative Fallbacks

Explanation

The new zero-timestamp exception is an unjustified fallback. poller.refreshOnce sets listedAt with time.Now() before listing sessions (internal/ui/poller.go:441), and it is the only non-test constructor of refreshMsg. The new logic in internal/ui/model.go:1570-1571 treats a zero listedAt as non-stale and accepts its row data even after a newer listing. Test-only direct refreshMsg literals do use zero timestamps, but they do not establish a production refresh shape. This fallback can silently bypass the stale-listing protection if an internal producer omits the required timestamp.

Resolution

Remove the zero-timestamp exception. Require every production refresh message to carry its listing timestamp, and reject or report a missing timestamp rather than treating that refresh as fresh. Keep the stale comparison and lastListedAt update based on valid timestamps.

Thanks @snowyukitty, nice fix! I tried it with a long list of sessions. On main, pressing J twice fast sometimes left the row where it started. On your branch it landed right every time, with every agent CLI we support. Tests pass here too.

Not blocking. A parent group that only exists because of a nested one (like work when you only made work/api) can still jump back on its first move, but only in a tiny timing window. Fine to leave for later.

Merged, thanks @snowyukitty! This goes out in the next release.

Brings the 45 upstream commits since dc471a9 into the proposal's owners instead of the files upstream changed: - Model/effort/profile choices (wainmann#672 and the catalog work) persist through the settings cache and a choice-save effect, not store calls on Update. - Keys and editor in Settings (wainmann#688) save through store.SetKeys on the effect lane; the background, fetch-on-spawn and editor rows join the settings read-back. - Group worktree bases (wainmann#680) travel in spawn, group, rename and rail-move requests; fork and spawn launch on the captured choice. - After-turn archive/kill (wainmann#703) runs Lifecycle.EndAfterTurn on the lane. - Upstream reorder marks (wainmann#683) are covered by the effect fence plus the listing timestamp; status, notify, tmux, CLI and Oh My Pi changes land in their concern files. The E2E settings scenarios step past the new background row. Co-Authored-By: Claude Opus 5.5 <[email protected]>
