A workspace created via the CLI on a remote host you own never appeared in the sidebar on another machine, even though the live workspace:changed feed already delivered it. usePlaceLocalWorktreesInSidebar filtered to workspace.hostId === machineId before ever considering placement, so an explicit worktree/session creation from a remote host or the CLI was silently dropped. v2Host.list is already scoped to hosts the signed-in user has access to, so widening this to every known host cannot leak another user's workspaces. isAutoIncludedLocalMainWorkspace (the ambient "main" workspace per project) stays local-only: it auto-adds a project's main workspace whenever that project is already in the sidebar, and broadening it would pull in a main workspace for every project on every known host, which is a bigger, more surprising behavior change than this bug calls for. Fixes superset-sh#5329

📝 WalkthroughWalkthroughThe desktop workspace flow now supports worktrees and sessions from all known hosts, persists workspace removal across live and fallback data, and skips unreachable-host subscriptions. Dialog cleanup releases stuck pointer-events locks. The event bus now reuses recently detached connections and stabilizes relay probe status updates. ChangesWorkspace lifecycle and sidebar behavior
Event-bus connection lifecycle
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟠 High · up to This PR expands remote-host workspace placement and changes deletion and connection cleanup behavior, but the desktop can still become permanently unclickable when dialog unmount timing races the lock cleanup, and stale responses can resurrect deleted workspaces. A briefly reused host connection could also carry the wrong authentication context when different identities share a URL. These current-head correctness, availability, and conditional security risks should be fixed or explicitly accepted before merging. Suggested reviewers: Sequence Diagram(s)sequenceDiagram

Converting to draft as I investigate a side-effect of the fix |
4 tasks
DashboardSidebarWorkspaceStatusProvider opened a live event-bus subscription and a terminal-agent-bindings query for every sidebar-visible workspace, gated only on whether its host was a sandbox. A host's self-reported `isOnline` flag stays true even when the relay tunnel in between is flaky, so a workspace on a host with a healthy host-service but a bad relay edge got a subscription that immediately failed and kept retrying — each reconnect/probe cycle invalidating bindings and diff-stats queries across every row on that host, compounding into a noticeably janky sidebar (reported as an apparent freeze after deleting a workspace on such a host, surfaced by superset-sh#6953 making remote-host workspaces sidebar-visible for the first time). Gate the fan-out on `hostReachable` (reflects the last live fetch's actual success, not the host's self-report) instead: a workspace on a currently unreachable host gets no subscription until the next successful poll re-admits it, rather than holding a socket open to a host failing every attempt.
…space Deleting a sidebar-visible workspace on a host behind a flaky relay could leave the whole app unresponsive to clicks until a reload. Confirmed live over CDP: document.body.style.pointerEvents stays "none" — Radix's DismissableLayer only restores it when the dialog layer unmounts through its exit transition, and closing the delete dialog while the cache update removes its sidebar row can unmount the layer before the transition completes, orphaning the lock (radix-ui/primitives#1859, superset-sh#2122). The destroy flow now releases a stuck lock once the dialog is done, guarded so it never touches a genuinely open dialog. Also fixes the reconnect storm that made the race so easy to lose against an unreachable host, at the shared event-bus layer: - Value-compare relay preflight probes: a fresh-but-identical 503 probe object per dial published a no-op status "transition" to every subscriber on every backoff attempt, driving React commits forever. - Linger 1s before closing a consumerless connection: effect churn (cleanup + re-run in one commit) used to destroy the socket and redial immediately with the backoff reset; a re-attaching consumer now reuses the live socket. - Persist optimistic workspace removal into the offline snapshot: with the host's deleted broadcast lost to the relay, the stale snapshot resurrected the deleted workspace on next launch, and the sidebar placement hook re-placed the ghost row.

Prevent pre-delete workspace.list responses from restoring the workspace.
A pending workspace.list query can resolve after removeWorkspace. The query function then persists stale rows and returns them to React Query, which can restore the deleted workspace in memory and after relaunch. Track a per-host removal generation or tombstone, and discard or filter stale responses before updating either store. Add a delayed-list regression test.

Move the entity-scoped snapshot to host-side SQLite.
Lines 417-421 persist a full HostWorkspaceRow[] list in renderer-side IndexedDB. This list is entity-scoped and unbounded. Move the snapshot path to an @superset/local-db schema through electronTrpc instead of extending this renderer persistence path.
As per coding guidelines, “Anything entity-scoped with unbounded cardinality, or payloads beyond a few KB, belongs in host-side SQLite (@superset/local-db schema, reached over electronTrpc).”

Run stale-lock cleanup after the close commit.
onOpenChange(false) schedules the controlled AlertDialog close, but DeleteWorkspaceMount stays mounted until onDeleted calls close(workspaceId). The asynchronous finally can run while the closing dialog still matches the selector, so releaseStuckBodyPointerEventsLock() returns. If unmount bypasses Radix cleanup, pointerEvents can remain "none" and block clicks. Run the check after React commits the close, and add a DOM regression test for this unmount path.

What this fixes
1. Sessions/workspaces created on a remote host now show up in the sidebar automatically (#5329).
usePlaceLocalWorktreesInSidebarfiltered toworkspace.hostId === machineIdbefore considering placement, so an explicit worktree/session created from another machine or the CLI was silently dropped even though the liveworkspace:changedfeed already delivered it. Placement now covers every known host;v2Host.listis already scoped to hosts the signed-in user can access, so nothing can leak. The ambient per-projectmainworkspace stays local-only.2. Deleting one of those workspaces no longer freezes the whole app.
Repro: a workspace on a remote host behind a flaky relay tunnel; delete it from the sidebar; the delete succeeds but shortly after the entire app stops responding to clicks until a reload. Confirmed live over CDP during a freeze:
document.body.style.pointerEventsis stuck at"none"while the main thread is idle — no hang, just an orphaned lock. Radix'sDismissableLayerlocks body pointer-events while a modal dialog is open and only restores it when the layer unmounts through its exit transition; closing the delete dialog while the cache update removes its sidebar row can unmount the layer before that transition completes, orphaning the lock permanently (same class as radix-ui/primitives#1859 / #2122). The destroy flow now releases a stuck lock once the dialog is done, guarded so it never touches a genuinely open dialog.Supporting fixes in the shared event-bus layer, which produced the constant re-render pressure against an unreachable host that made the race so easy to lose (and are worth having regardless):
{status: 503}probe object, and identity comparison turned each one into a status "transition" broadcast to every subscriber → React commits on every retry, forever, while a host stayed down.deletedbroadcast lost to the flaky relay, the stale snapshot resurrected the deleted workspace on the next launch, and (now that remote workspaces are sidebar-placed) re-placed the ghost row.Also includes the earlier commit gating the sidebar status fan-out on
hostReachableinstead of the host's self-reportedisOnline— it wasn't sufficient on its own but is correct: no point holding live subscriptions to a host failing every attempt.Verified
Reproduced and diagnosed against a real remote host with an intermittently failing relay edge (production build + CDP). With these changes, create-on-remote → appears in sidebar → delete → no freeze, through multiple reconnect cycles.
packages/workspace-clienttests pass (incl. a new linger test); desktop typechecks.Heads-up for review: the code is a bit messy
This grew out of a live debugging session and it shows — flagging it rather than pretending otherwise:
releaseStuckBodyPointerEventsLock()is an app-level band-aid for a Radix-layer race: it pokesdocument.body.styledirectly and lives in the destroy-dialog hook because that's the flow that reproducibly loses the race, but any Radix modal whose container is removed mid-exit could hit the same bug. A more principled home (shared dialog wrapper, or upstreaming to Radix) is a fair ask.CONNECTION_LINGER_MS = 1_000is a judgment call (long enough to cover same-commit effect churn, short enough that a sandbox VM's keep-awake window barely moves).🤖 Generated with Claude Code
