ApprovabilityVerdict: Approved at Macroscope's review found this PR approvable — This focused web bug fix binds terminal close RPCs, fallback writes, and local cleanup to the thread captured when confirmation began, preventing a delayed confirmation from closing another thread's terminal. Existing close paths remain behaviorally equivalent, and a targeted browser regression test covers the affected flows. You can add or adjust custom eligibility rules. Learn more. |

Close callbacks accept an optional thread reference. Terminal exit, confirmation, and surface-resource release pass the relevant reference to terminal closure. A browser test checks that a deferred close retains the original thread reference. |

Terminal closure checks the target thread’s operate scope and uses its environment and thread IDs. Terminal and panel state updates apply to that thread. Tests cover thread changes, successful and fallback closes, cancellation, and revoked scope. |

Pass the captured thread reference on session-exit closes.
onSessionExited runs asynchronously. TerminalSplitPanes passes threadRef to TerminalViewport, but omits it when closing the terminal. The parent close callback defaults to its current thread, so a reused terminal ID can close the wrong session after navigation.
Suggested fix
-
- onCloseTerminal: (terminalId: string) => void; + onCloseTerminal: (terminalId: string, threadRef?: ScopedThreadRef) => void; ... - onSessionExited={() => onCloseTerminal(terminalId)} + onSessionExited={() => onCloseTerminal(terminalId, threadRef)}

A terminal's exit close runs on a later task, after the drawer may have moved to another thread. The split panes dropped the thread they captured, so the panel close fell back to the active thread and could close a reused terminal ID there. Pass the captured thread through.

Note Written by thanks @only21mil. your captured destination fixes the wrong-thread close and preserves the same destination for the permission check, close rpc, and exit fallback. i updated this branch directly and kept all contributor commits. merged current main ( verification at
unverified: native desktop shell, mobile, other browsers and windows. fallback failures and revoked permissions are covered by deterministic browser regressions rather than forced on the real server. web and desktop share this renderer; the server protocol and provider adapters are unchanged. gitcafe currently renders these external media embeds as links; the uploaded files were opened and verified directly. before, b loses its terminal after confirming a's close: after, b keeps its running counter and a's process has exited: |
Problem
A terminal close confirmation can stop a different thread's terminal and delete its history. Terminal IDs such as
term-1are reused across threads.Open terminals in A and B. Visit B, then A. Close A's terminal tab, use browser Back while its confirmation is open, and confirm from B. Local cleanup still belongs to A, but the stable terminal callback uses B's latest thread reference. B loses its terminal while A's process keeps running.
Change
Pass the captured scoped thread reference through terminal close operations. The permission check, close RPC, and
exitfallback use that same destination, even after another thread or environment becomes active.The panel tab close passes its original reference. The terminal toolbar also passes the reference captured before confirmation through its retained callback. Panel cleanup finds the terminal's surface in the destination thread's current store, so a newer selected panel cannot redirect cleanup. The drawer uses the same explicit destination for its session and local state. Stable callback identities stay unchanged.
Scope and approval
This is a focused repair for an obvious wrong-destination destructive action under the small-fix exception in CONTRIBUTING.md. There is no issue or maintainer approval claimed for this finding. Confirmation defaults, wording, terminal ID allocation, and the server protocol stay the same.
The change covers the shared web renderer used by desktop. Mobile has separate terminal controls and is untouched.
Verification
The Chromium regression defers a confirmation, rerenders the actual hooks for another environment and thread with the same terminal ID, then resolves it. Both successful close and the
exitfallback fail on the base and pass with the fix. Cancel and revoked access preserve both sessions. The four cases pass on the final source tree.Commands from the repository root:
Formatting, lint, typecheck, and production builds pass. The base has two regression failures and two passing guard cases; the candidate passes all four.
Real-app verification used Chrome 154 on Linux, production web bundles, a production server on macOS, and separate state for each build. Two real PTYs ran counters in
term-1, without a provider session. After confirming A's close from B, the base has A running and B missing. The candidate has A missing and B still running. Repeating the candidate flow with the terminal toolbar's close button also leaves B running and closes A.Not checked: native desktop shell integration, other browsers, Windows, or mobile. The fallback failure and permission changes were checked in the deterministic browser regression, rather than forced in the real server.
Before: confirming A's close after navigating to B removes B's terminal panel.
After: the same steps close A and leave B's terminal and counter running.
Recordings of the same interaction, before and after.
The regression fails on the base and passes with the fix.
Prior PRs: #20289 by Julius Marminge introduced the shared terminal actions hook used here. #8421 by Adolanium addressed the close fallback and was closed because that fallback already existed on main; this fix preserves it. #16615 by Jake Leventhal changes confirmation preferences and bulk close, which are separate from this wrong-thread repair.
