From 08bf209e404a8d56519c5a2cb0a7204ef7eb99b5 Mon Sep 17 00:00:00 2001 From: Neil <4138956+nwparker@users.noreply.github.com> Date: Sun, 16 Aug 2026 22:18:50 -0700 Subject: [PATCH 001/129] fix(ci): run PR LoC scripts from the default branch, not PR head (#15016) The PR test LoC job fetched .github/scripts/pr-test-loc-*.mjs from pull//head and ran them with node while holding a GITHUB_TOKEN scoped pull-requests: write, so PR-authored code executed under a write token. Pin the fetch to the repository default branch. base.sha is not enough: for stacked PRs it is an unreviewed feature-branch commit any collaborator can push to, while main is gated by branch protection. Also pass event data via env instead of shell interpolation, and add set -euo pipefail so a failed download cannot leave a truncated script. --- .github/workflows/pr-test-loc.yml | 10 ++++- config/scripts/pr-test-loc-summary.test.mjs | 47 +++++++++++++++------ 2 files changed, 42 insertions(+), 15 deletions(-) diff --git a/.github/workflows/pr-test-loc.yml b/.github/workflows/pr-test-loc.yml index 438951ee3fa..a884aedc636 100644 --- a/.github/workflows/pr-test-loc.yml +++ b/.github/workflows/pr-test-loc.yml @@ -23,14 +23,20 @@ jobs: timeout-minutes: 2 steps: # Why no checkout: the Files API already has per-file additions/deletions. + # Why the default branch and never pull//head: this job holds a write-scoped + # GITHUB_TOKEN, so it may only execute reviewed code.

Both switches then matched nothing and returned undefined, which rendered as a blank toast.warning(undefined). #14683 replaced the absorbing default: arm with case 'unknown' to satisfy switch-exhaustiveness-check, which forbids default: on an exhaustive switch. Guard before each switch instead: narrow the wire value against the handled set and route anything else to a generic message. The handled sets are keyed by the unions themselves, so a fourth member still fails typecheck here. * fix(browser): reject non-string cookie-import warning discriminants Object.hasOwn coerces its key, so the membership guards admitted any value whose toString() matched a handled variant. A host that widened reason to an array sends ['unknown'], which passed the guard and then fell straight back out of the switch -- the same undefined-to-toast.warning blank the guards exist to prevent. Take unknown and check typeof first, matching isTopLevelView and isTuiAgent. The Record membership sets still fail typecheck on a new union member. --- src/renderer/src/i18n/locales/en.json | 4 +- .../lib/browser-cookie-import-toast.test.ts | 80 +++++++++++++++++++ .../src/lib/browser-cookie-import-toast.ts | 44 +++++++++- 3 files changed, 126 insertions(+), 2 deletions(-) diff --git a/src/renderer/src/i18n/locales/en.json b/src/renderer/src/i18n/locales/en.json index bacd04d4ba1..a66f2e3b481 100644 --- a/src/renderer/src/i18n/locales/en.json +++ b/src/renderer/src/i18n/locales/en.json @@ -788,7 +788,9 @@ "undecryptableAppBoundMixed": "Orca cannot decrypt {{value0}} of this browser's cookies because they use app-bound encryption; {{value1}} more could not be decrypted for another reason.

Validate mutation results to surface silent no-ops. Extract circuit-break threshold, add transaction wrapping, and sanitize untrusted input. Bump schema version to v28. * Add transactional safety to dispatch and message operations Wrap dispatch failures and batched message updates with SAVEPOINTs to ensure atomicity and idempotency: - Dispatch failures now check status guards and roll back if the related task update fails, preventing partial state corruption - Message batches (across multiple 500-id chunks) roll back entirely if any batch fails, avoiding partial mutations - Add tests verifying idempotency and atomicity under failure conditions * Handle concurrent writes and improve transactional safety - Remote question answering: add classification check before and after UPDATE to safely detect concurrent modifications. Prevents false success when the UPDATE loses a race. - Transaction rollback: wrap in try-catch to prevent errors from masking the original failure. - Question thread reset: use status update instead of deletion to preserve message references. * test: add answer replay and race condition edge case coverage Add test cases for answer replay idempotency, conflict detection, and a race condition between concurrent answer updates in federation relay. Also verify local question state transitions during orchestration reset. --- config/max-lines-baseline.txt | 1 - src/main/runtime/orchestration/db.ts | 7761 +----------------

charset=UTF-8 Content-Transfer-Encoding: 8bit The chord held for a live composition waits with `fallbackMs: null`, so nothing but compositionend can end it. `sendTerminalInputAfterComposition` returned void, so nobody could stop it either: the two listeners it puts on the terminal element outlived the pane, and a later composition on that element flushed the stale chord. Return a disposer from the helper and put a sender in front of it that owns every pending chord, so blur and pane teardown drop them the way the Enter path already clears its state. The sender also bounds the wait — generous enough for a conversion candidate window, and it discards rather than sends, because a chord arriving mid-preedit is the corruption the wait exists to prevent. The Enter path needs none of this: its 200 ms fallback always runs, so its listeners cannot outlive it. Pinned so that stays true.

Every consumer derives "installed" from the skill list, so an unreadable root read as proof the skill was gone and an already-installed skill offered Install again. - discovery: retain the last answered scan per root (5 min, LRU-bounded, dropped on install/update invalidation and when a root answers as absent) and serve it when a later scan goes unavailable. - source inventory: an unanswered root reports `exists: true`, so check `skippedReason` first rather than presenting it as a successful scan. - useInstalledAgentSkills: when an in-scope root did not answer and the skill was not found, say the status may be incomplete instead of a bare "Not installed". * fix(skills): do not let install verification accept an unanswered root's retained scan Retention makes discovery serve a stalled root's last completed scan, which is the state before an install wrote. Verification read that as proof, so reinstalling a skill into a root that stalled could report success without reading what it wrote — turning a retryable false negative into a false positive. A match now counts only when a root that actually answered reached the skill, so a symlinked placement co-owned by a healthy root still verifies. --- src/main/skills/discovery.test.ts | 80

History GC deleted folder-workspace shell history. The live set was built from `getAllWorktreeMeta()` alone, but a folder workspace's PTY carries `folder:` as its worktree id, so every live folder workspace looked orphaned. `getKnownWorktreeIdsForHistoryGc` now unions in `getFolderWorkspaces()`. Both consumers — the history-directory prune and the fish-history sweep — read that one set, so the fix covers bash, zsh and fish history alike. The directory prune had this gap since #1524; #14863 only widened its blast radius to fish files. 2. A copied Codex resume command aborted under `set -u`. Its leading clear statement has to test `$fish_pid`, and that unbound expansion takes the whole line — including the agent launch — down with it. Copied text runs in a shell Orca never spawned, so nothing can seed that variable first. The removal now rides on the agent itself as `env -u`, which needs no shell syntax and no expansion. Verified byte-identical under `set -u` in sh, bash, zsh, dash, ksh and fish. `env` cannot run the `cd` builtin, and a child `cd` would not move the agent, so the prefix is placed on the agent rather than on the whole `cd … && agent` chain. cmd and PowerShell have no nounset hazard and keep their clear ahead of the `cd`, which preserves `cd … && agent` — a failed `cd` still cannot launch the agent in the wrong directory. * fix(history-gc): stop three more paths from deleting live shell history Found by adversarial review of the reland. All three are the same class as the bug that caused the revert: a live set that is missing a category of real workspace, so the GC reads it as orphaned. 1. Profiles. The history root is `userData/terminal-history`, which has no profile segment, but the Store the GC consults is per-profile. So after a profile switch the live set condemned every other profile's history — and fish history, which lands in the user's own fish data dir, is shared by every profile on the machine. The live set now unions in the inactive profiles' worktrees and folder workspaces, read from their data files. A profile whose ids cannot be read reports the empty set rather than one that condemns real history. 2. No empty-set guard on the tree scan. `sweepOrphanedFishHistoryFiles` refuses an empty live set because it cannot be told apart from a store that failed to hydrate; the directory scan, which deletes more, had no such guard. A store that fell back to default state would have taken every worktree's bash and zsh history with it, across all roots including WSL. Four existing tests passed `new Set()` and relied on "empty means everything is orphaned" — exactly the behavior being removed — so they now pass a real live set. 3. Relay fish history. The relay isolates its history tree under its own root but wrote fish history into the shared fish data dir under the desktop naming, keyed by the CLIENT's worktree ids. On a machine running both Orca and a relay host, the desktop sweep deleted remote sessions' history once it went stale. Relay files are now `orca_relay_`, which the sweep's pattern deliberately does not match; the relay still deletes them by exact name when the worktree goes away. * fix(resume): enforce the env-removal invariants instead of documenting them Both found by adversarial review; both were unreachable from today's callers and silent if reached, which is exactly how they would survive to a caller that does reach them. - A pinned CODEX_HOME and the removal named the same variable, and `env -u` strips what the assignment just set — so the agent would have resumed against the real home and not found the session. The removal list now excludes any name the prefix pins, keeping the assignment authoritative as the old `clear…; CODEX_HOME=x agent` ordering did. Same fix in the git-bash twin. The PowerShell branch already clears before it assigns, so it was never affected. - Placement was keyed on the platform while the grammar it selects is keyed on the shell, so `platform: 'linux'` with `shell: 'powershell'` emitted POSIX `env -u` into a PowerShell line. PowerShell now routes to the PowerShell builder whatever the host, and the POSIX/cmd split below asks the shell rather than the platform. --- .github/workflows/pr.yml | 6 +

Kana and kanji are not in the table, so a Japanese reading streamed to the PTY one fragment at a time and was repaired afterwards with DEL bytes (#7427). A code-point table cannot work, and the counterexample is not exotic: Chinese pinyin preedit is plain ASCII, and a Japanese romaji reading is one code point on the first keystroke and three on the fourth. Preedit is a property of the FIELD, not of the characters in it, so the only signal that identifies it is the text system's marked-text range. That is what a reference terminal implementation uses on every platform it supports - `hasMarkedText` there, the input-method context's composing state elsewhere - and neither one classifies code points anywhere in the input path. So the mirror now takes the marked-text report per change and holds the whole preedit region, whatever its length or script: - Subscribe the capture field to `onChange`, not `onChangeText`; only the raw native event carries the report at all. - A reported preedit is held entire and is never committed by the settle timer, because preedit is not text yet. Explicit boundaries still flush it. - `isTerminalLiveHangulCodePoint` and its four ranges are deleted. iOS reports the range but React Native drops it before JS, so the pinned patch forwards `markedTextRange` into the change payload. It is three hunks and it compiles because the app already sets `buildReactNativeFromSource` for iOS. The same idea was proposed in #11450, which is where the patch comes from. Android has no marked-text report in React Native at all, and a Kotlin patch would not help: Android consumes the prebuilt react-android artifact, so node_modules sources are never compiled. Until the report exists there, the fallback holds the trailing non-ASCII run. It enumerates nothing, it covers kana, kanji and Hangul, and ASCII keeps its zero-latency echo - but it cannot see an ASCII preedit, so Chinese pinyin on Android still leaks its reading. Only a report fixes that. Not-tested: no physical device or emulator was available, so no real IME drove this path. Japanese, Chinese and Korean composition are covered at the model and hook level only, and the iOS patch has not been compiled. Co-authored-by: Brennan Benson * fix(mobile): bound the fallback hold to text the pty has not received The no-report branch walked the trailing non-ASCII run over the whole field and ignored stableLength, unlike the reported branch directly above it. So after a settle-timer commit the next keystroke re-held everything already delivered and the caller erased it with DEL and retyped it — a nine-character Cyrillic word cost a DEL per already-sent character, and for the 300ms before the re-send the held text was the only copy, so a blur or reconnect destroyed characters the pty already had. Bound it the way the reported branch is bounded. Pinned by a test that drives a settle commit between every keystroke and asserts no DEL reaches the wire. --------- Co-authored-by: Brennan Benson --- .../app/h/[hostId]/session/[worktreeId].tsx | 4 +- mobile/package.json | 3 + mobile/patches/react-native@0.83.9.patch | 48 +++ mobile/pnpm-lock.yaml | 5 + .../terminal-ios-ime-keyboard.test.ts | 7 + .../terminal-live-hangul-mirror.test.ts | 178 ---------- .../terminal/terminal-live-hangul-mirror.ts | 61 ---- .../terminal-live-preedit-mirror.test.ts | 304 ++++++++++++++++++ .../terminal/terminal-live-preedit-mirror.ts | 83 +++++ .../use-terminal-live-input-commit.test.ts | 109 +++++-- .../use-terminal-live-input-commit.ts | 22 +- .../use-terminal-live-pending-input-flush.ts | 35 +- 12 files changed, 568 insertions(+), 291 deletions(-) create mode 100644 mobile/patches/react-native@0.83.9.patch delete mode 100644 mobile/src/terminal/terminal-live-hangul-mirror.test.ts delete mode 100644 mobile/src/terminal/terminal-live-hangul-mirror.ts create mode 100644 mobile/src/terminal/terminal-live-preedit-mirror.test.ts create mode 100644 mobile/src/terminal/terminal-live-preedit-mirror.ts diff --git a/mobile/app/h/[hostId]/session/[worktreeId].tsx b/mobile/app/h/[hostId]/session/[worktreeId].tsx index 6cff5a841fd..5587c204316 100644 --- a/mobile/app/h/[hostId]/session/[worktreeId].tsx +++ b/mobile/app/h/[hostId]/session/[worktreeId].tsx @@ -4944,7 +4944,9 @@ export default function SessionScreen() { ref={liveInputRef} style={styles.liveInputCapture} value={liveInputCapture} - onChangeText={handleLiveInputChange} + // Why onChange, not onChangeText: only the raw native event carries the + // marked-text report that says whether this text is still preedit. + onChange={handleLiveInputChange} onKeyPress={handleLiveInputKeyPress} onSubmitEditing={handleLiveInputSubmit} placeholder="" diff --git a/mobile/package.json b/mobile/package.json index 4b4274bb9d0..75db0998903 100644 --- a/mobile/package.json +++ b/mobile/package.json @@ -85,6 +85,9 @@ "pnpm": { "overrides": { "xcode>uuid": "11.1.1" + }, + "patchedDependencies": { + "react-native@0.83.9": "patches/react-native@0.83.9.patch" } } } diff --git a/mobile/patches/react-native@0.83.9.patch b/mobile/patches/react-native@0.83.9.patch new file mode 100644 index 00000000000..102b052746b --- /dev/null +++ b/mobile/patches/react-native@0.83.9.patch @@ -0,0 +1,48 @@ +diff --git a/React/Fabric/Mounting/ComponentViews/TextInput/RCTTextInputComponentView.mm b/React/Fabric/Mounting/ComponentViews/TextInput/RCTTextInputComponentView.mm +index d02e003a439e410ddab597b2c036256c80db0395..3caff21b0d00bfbc6dea3f8470e812b8343ac3a2 100644 +--- a/React/Fabric/Mounting/ComponentViews/TextInput/RCTTextInputComponentView.mm ++++ b/React/Fabric/Mounting/ComponentViews/TextInput/RCTTextInputComponentView.mm +@@ -703,6 +703,7 @@ static NSSet *returnKeyTypesSet;

fix(ssh): stop reporting a confirmed kill when the SSH provider is gone (#14977) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * fix(ssh): stop reporting a confirmed kill when the SSH provider is gone A detached relay PTY is designed to outlive the provider that addressed it (it ignores SIGHUP and ships with an unlimited grace), so "the SSH provider is no longer registered" is lost contact, never evidence the remote process stopped. Both stop primitives in the PTY controller returned `true` from that branch, and every caller downstream reported the fabricated success: the CLI printed "PTY killed.", worker-stop settled the dispatch as stopped, and — because the stop "succeeded" — the unstopped-PTY gate never ran, so worktree removal walked straight past a live remote agent. `kill`/`stopAndWait` now still tombstone the local lease but report an unconfirmed stop and record why, using the three-verdict vocabulary the worktree teardown gate already spoke (`live` / `unverifiable` / `exited`), promoted out of that module into `src/shared/pty-liveness-verdict.ts`. The close receipt, the CLI wording, worker-stop and the removal gate all read that verdict instead of inferring an exit from silence. The same rule fixes the mirror-image defect: the aggregate inventory only enumerates registered providers, so a dropped relay clears `connected` for every remote PTY at once. The sweep now separates the provider answering "absent" (an exit) from no provider being able to answer (lost contact), so worker-stop stops claiming `exited` from a disconnect. The `connected` wire field is unchanged in meaning and shape. * fix(orchestration): apply the same honesty to the federation stop path The federation host runs its own copy of the worker observation and stop logic, with the same two defects: `inspectRemoteAttachment` read a dropped relay's `connected: false` as `exited`, and `federationStop` settled the dispatch as stopped from a close it never confirmed — relaying a fabricated success all the way home to the coordinator. Two guards also had to move so the honest verdict does not become a new refusal. `federationRead` gated on `status !== 'running'`, which would have rejected a connected terminal the moment a stop lost contact with it; it now gates on `status === 'exited'`, which is equivalent for every pre-existing status given the two guards beside it. Local `workerStop` likewise still attempts the close when the verdict is `unverifiable` — losing contact is a reason to report the outcome honestly, never a reason to stop trying. The show observations now carry the reason alongside the status, so a bare `unverifiable` is actionable. Both are new optional fields. * fix(ssh): preserve unconfirmed stop verdicts across consumers * fix(ssh): use canonical live verdict wording * fix(ssh): refuse wrong-host teardown verification * test(orchestration): confirm worker release teardown * fix(orchestration): negotiate honest worker stop receipts * fix(agent-teams): fence uncertain teammate respawns * fix(ssh): avoid duplicate missing-provider teardown * fix(orchestration): preserve archives across release retries * fix(ssh): preserve verdicts across synthetic kill exits * fix(ssh): preserve liveness evidence across teardown * fix(agent-teams): replace panes only after confirmed stop * fix(ssh): distinguish host exits from relay loss * fix(ssh): narrow concurrent inventory verdicts * fix(orchestration): serve archives after uncertain release * fix(orchestration): expose unverifiable read liveness * test(ssh): align liveness assertions with verdicts * fix(ssh): preserve host scope across inventory failures --- src/cli/terminal-format.test.ts | 39 ++- src/cli/terminal-format.ts | 18 +- .../process-gone-killed-one-ordering.test.ts | 7 +- .../process-gone-recorder.test.ts | 4 +- .../pty-daemon-controller-teardown.test.ts | 27 +- .../pty-daemon-ssh-lease-lifecycle.test.ts | 2 +- .../ipc/pty-runtime-kill-and-exit.test.ts | 25 +- src/main/ipc/pty-ssh-stop-verdict.test.ts | 297 ++++++++++++++++++ src/main/ipc/pty.ts | 119 +++++-- .../claude-agent-teams-service.test.ts | 57 +++- .../claude-agent-teams-tmux-dispatcher.ts | 42 ++- src/main/runtime/claude-agent-teams-types.ts | 1 + ...ntime-process-incarnation-liveness.test.ts | 16 +- ...-runtime-terminal-close-continuity.test.ts | 73 ++++- ...a-runtime-terminal-split-authority.test.ts | 6 +- src/main/runtime/orca-runtime.ts | 212 +++++++++++-- .../worker-terminal-release.ts | 5 +- .../worker-terminal-process-liveness.ts | 6 +- .../pty-inventory-liveness-verdict.test.ts | 194 ++++++++++++ .../orchestration-federation-control.ts | 72 ++++- ...ration-federation-liveness-verdict.test.ts | 183 +++++++++++ .../orchestration-federation-output.test.ts | 2 +- .../orchestration-federation-setup.test.ts | 1 + .../methods/orchestration-federation.test.ts | 5 +- .../methods/orchestration-worker-control.ts | 28 +- .../orchestration-worker-observation.ts | 21 +- .../orchestration-worker-output.test.ts | 13 + .../methods/orchestration-worker-output.ts | 13 +- ...orchestration-worker-release-completion.ts | 15 +- ...on-worker-release-liveness-verdict.test.ts | 84 +++++ ...hestration-worker-release-recovery.test.ts | 35 ++- .../orchestration-worker-release.test.ts | 15 +- .../methods/orchestration-worker-release.ts | 2 +- ...chestration-worker-stop-capability.test.ts | 57 ++++ ...ation-worker-stop-liveness-verdict.test.ts | 158 ++++++++++ .../rpc/methods/orchestration-worker-stop.ts | 37 ++- .../orchestration-workers-recovery.test.ts | 5 +- .../runtime/unstopped-pty-verification.ts | 49 ++- .../worktree-teardown-unstopped-pty.test.ts | 74 +++++ src/main/runtime/worktree-teardown.test.ts | 47 ++- src/main/runtime/worktree-teardown.ts | 21 +- .../commit-message-text-generation.ts | 4 +- src/shared/orchestration-worker-output.ts | 3 + src/shared/protocol-version.ts | 3 + src/shared/pty-liveness-verdict.ts | 34 ++ src/shared/runtime-types.ts | 8 + 46 files changed, 1978 insertions(+), 161 deletions(-) create mode 100644 src/main/ipc/pty-ssh-stop-verdict.test.ts create mode 100644 src/main/runtime/pty-inventory-liveness-verdict.test.ts create mode 100644 src/main/runtime/rpc/methods/orchestration-federation-liveness-verdict.test.ts create mode 100644 src/main/runtime/rpc/methods/orchestration-worker-release-liveness-verdict.test.ts create mode 100644 src/main/runtime/rpc/methods/orchestration-worker-stop-capability.test.ts create mode 100644 src/main/runtime/rpc/methods/orchestration-worker-stop-liveness-verdict.test.ts create mode 100644 src/shared/pty-liveness-verdict.ts diff --git a/src/cli/terminal-format.test.ts b/src/cli/terminal-format.test.ts index 014f6339823..0656234e292 100644 --- a/src/cli/terminal-format.test.ts +++ b/src/cli/terminal-format.test.ts @@ -1,5 +1,5 @@ import { describe, expect, it } from 'vitest' -import { formatTerminalFocus } from './terminal-format' +import { formatTerminalClose, formatTerminalFocus } from './terminal-format' describe('formatTerminalFocus', () => { it('distinguishes superseded navigation from a winning focus', () => { @@ -22,3 +22,40 @@ describe('formatTerminalFocus', () => { ).toBe('Focused terminal term_winner (tab tab-winner).') }) }) + +describe('formatTerminalClose', () => { + it('prints "PTY killed." only for a confirmed kill', () => { + expect( + formatTerminalClose({ close: { handle: 'term_local', tabId: 'tab-1', ptyKilled: true } }) + ).toBe('Closed terminal term_local.

With connectionId set but the provider unregistered (dropped connection, not yet reattached) they fell through to client-side git with cwd pointing at the remote repoPath — on a machine with a same-named local path that silently answers for the wrong repository. getCurrentHeadOid feeds shouldHideMergedImplicitPR, so a wrong OID changes which PR the UI attributes to a worktree. Both now take their existing unknown path (null / probeFailed) instead, matching repo-default-branch.ts. Local and WSL routing is unchanged. * fix(github): preserve PR state when SSH probes fail * fix(github): keep failed SSH discovery unverifiable * fix(github): propagate SSH identity failures * fix(github): scope verified SSH identity probes * test(github): preserve tolerant resolver calls * fix(github): preserve indeterminate auth discovery * fix(github): isolate SSH repository probe generations * test(github): expose SSH probe generation in mocks --- src/main/git/remote-url-probe.test.ts | 9 + src/main/git/remote-url-probe.ts | 13 +- .../github/client-pr-local-runtime.test.ts | 1 + ...nt-ssh-provider-execution-boundary.test.ts | 266 ++++++++++++++++++ src/main/github/client-test-mocks.ts | 12 +- src/main/github/client.ts | 46 ++- src/main/github/gh-utils.ts | 1 + .../github/github-api-repository-probe.ts | 25 ++ .../github-api-repository-validation.ts | 20 ++ src/main/github/github-api-repository.test.ts | 66 +++++ src/main/github/github-api-repository.ts | 115 ++++---- .../github/github-enterprise-repository.ts | 33 ++- src/main/github/github-repository-host.ts | 18 ++ ...repository-identity.ssh-host-alias.test.ts | 67 ++++- src/main/github/github-repository-identity.ts | 47 +++- 15 files changed, 641 insertions(+), 98 deletions(-) create mode 100644 src/main/github/client-ssh-provider-execution-boundary.test.ts create mode 100644 src/main/github/github-api-repository-probe.ts create mode 100644 src/main/github/github-api-repository-validation.ts create mode 100644 src/main/github/github-repository-host.ts diff --git a/src/main/git/remote-url-probe.test.ts b/src/main/git/remote-url-probe.test.ts index 8a7672cb229..f9e0348c3ac 100644 --- a/src/main/git/remote-url-probe.test.ts +++ b/src/main/git/remote-url-probe.test.ts @@ -97,6 +97,15 @@ describe('remote URL probe', () => { await expect(assertRemoteUrlReadable({ repoPath: '/repo' })).resolves.toBeUndefined() }) + it('keeps a failed SSH command unverifiable even without a transport error string', async () => { + const failure = new Error('relay request failed') + getSshGitProviderMock.mockReturnValue({ exec: vi.fn().mockRejectedValue(failure) }) + + await expect( + assertRemoteUrlReadable({ repoPath: '/repo', connectionId: 'ssh-1' }) + ).rejects.toBe(failure) + }) + it('does not turn a missing SSH provider into a false readable result', async () => { getSshGitProviderMock.mockReturnValue(null) diff --git a/src/main/git/remote-url-probe.ts b/src/main/git/remote-url-probe.ts index 7b18c1deac9..d237bdd98fa 100644 --- a/src/main/git/remote-url-probe.ts +++ b/src/main/git/remote-url-probe.ts @@ -3,6 +3,7 @@ import { SSH_GIT_PROVIDER_UNAVAILABLE_MESSAGE } from '../providers/ssh-git-dispatch' import { gitExecFileAsync } from './runner' +import { isStableMissingGitRemoteError } from './stable-missing-git-remote-error' /** * The `git remote get-url` probe every forge integration runs to decide whether @@ -91,10 +92,9 @@ export function isTransientGitProbeError(error: unknown): boolean { } /** - * Throws when the remote could not be read because the probe was wedged or its - * transport was gone, and returns normally for every answer — including a repo - * with no remote at all.

Composing mid-line hid the character at the cursor for the whole composition. The preedit overlay is an opaque box anchored to the cursor cell, and nothing reaches the pty while composing, so those cells still held their characters — the box simply covered them. `CompositionHelper` now draws the rest of the row after the preedit inside the view, so the composition reads as inserted text pushing the tail right. Four details come with it: - The view is start-anchored while it carries a tail, so the preedit stays put and the pushed tail clips at the right edge; alone, `rtl` still keeps a long preedit's end in view. - It is themed from `options.theme` instead of the stock `#000`/`#FFF`, with any alpha dropped — the view masks the cells it draws over, so a see-through background would re-expose the very characters the tail stands in for. - The helper textarea syncs to the preedit's own bounds, so IME candidate dialogs anchor to the composing text rather than past the rendered tail. - A TUI can repaint the row under an open composition, so `updateCompositionElements` — which already runs on every render — re-reads the remainder and re-renders on change. A string compare adds no layout read. The tail is read with an explicit end column: the cacheable form of `translateToString` arms the line string cache's self-renewing idle-clear timer, and the composition path must own no timers. Geometry is not the cause. Two mature reference terminal implementations compose marked text into the grid rather than into a floating box, and both still blank the cells under it — one of them literally substitutes the marked characters into the row's character array before rasterizing. Moving off the overlay would not have fixed this report; rendering the covered tail is what does. The e2e arm asserts the invariant an opaque overlay owes the grid: it must render every committed cell its bounding rect covers. That is measured from the real rect against the real cell grid, so it fails on the unfixed build with `covers "하" / renders "가"`. Known limitation: the rendered tail is plain-styled while composing (theme foreground on theme background, no per-cell colors); colors return on commit. This is inherent to the overlay, and drawing the preedit into the cell renderer instead would be a far larger change. Co-authored-by: rayim * test(e2e): assert the occlusion invariant, not the runner's cell width CI covered four columns where this machine covers two — 34.4px over an 8.43px grid against 12.3px over an 8px grid — so pinning the covered text verbatim pinned the font metrics rather than the behaviour. Assert instead that every committed cell the overlay covers appears in what it draws, which is the actual invariant and holds at any cell width. Still fails against main: covers "하" / renders "가". * fix(terminal): keep the rendered tail's spacing on the grid The composition view is white-space: nowrap, which collapses runs of spaces exactly like normal — it only suppresses wrapping. So a committed tail carrying padding drew its trailing glyph cells left of where the grid has them: measured in Chromium with xterm's own rule, twenty spaces plus a border rendered two cells wide instead of twenty-one. The visible case is Orca's most common IME context — composing inside an agent TUI input box, where the row is a prompt, padding, then a real border glyph the trim cannot drop. A stray border appeared a cell after the preedit while the real one stayed put. xterm sets white-space: pre on its grid rows for this reason; the view was only nowrap-safe while it held preedit text alone. The existing fixtures are all space-free, and the e2e invariant is that the overlay renders everything it covers — collapsing makes it cover less, so both stayed green. Pinned with a padded-row fixture. --------- Co-authored-by: rayim --- .../@xterm__xterm@6.1.0-beta.287.patch | 184 ++++++++++-- pnpm-lock.yaml | 48 ++-- ...nal-ime-xterm-midline-preedit-tail.test.ts |

ANSI/DEC compatible parser described by\n * Paul Williams (https://vt100.net/emu/dec_ansi_parser).\n *\n * To implement custom ANSI compliant escape sequences it is not needed to\n * alter this parser, instead consider registering a custom handler.\n * For non ANSI compliant sequences change the transition table with\n * the optional `transitions` constructor argument and\n * reimplement the `parse` method.\n *\n * This parser is currently hardcoded to operate in ZDM (Zero Default Mode)\n * as suggested by the original parser, thus empty parameters are set to 0.\n * This is not in line with the latest ECMA-48 specification\n * (ZDM was part of the early specs and got completely removed later on).\n *\n * Other than the original parser from vt100.net this parser supports\n * sub parameters in digital parameters separated by colons. Empty sub parameters\n * are set to -1 (no ZDM for sub parameters).\n *\n * About prefix and intermediate bytes:\n * This parser follows the assumptions of the vt100.net parser with these restrictions:\n * - only one prefix byte is allowed as first parameter byte, byte range 0x3c .. 0x3f\n * - max. two intermediates are respected, byte range 0x20 .. 0x2f\n * Note that this is not in line with ECMA-48 which does not limit either of those.\n * Furthermore ECMA-48 allows the prefix byte range at any param byte position. Currently\n * there are no known sequences that follow the broader definition of the specification.\n *\n * TODO: implement error recovery hook via error handler return values\n */\nexport class EscapeSequenceParser extends Disposable implements IEscapeSequenceParser {\n public initialState: number;\n public currentState: number;\n public precedingJoinState: number;

Rewrite only when the root really is a WSL UNC path, and cover the legacy wsl$ alias, cross-distro paths, and the non-WSL case. * test(cli): pin WSL_DISTRO_NAME absent for the whole file-path suite Contributors run this suite inside WSL, where the inherited distro name would flip the rewrite on for every POSIX-root case. * fix(cli): never rewrite a Linux path that contains a backslash Backslash is a legal Linux filename character but a separator once the path reads as UNC, so `a\b.ts` relativized to `a/b.ts` — a different file. Such a path has no UNC spelling; let it fail the match instead. * test(cli): pin the WSL rewrite's negative space Sibling-prefix roots, Linux-tail case sensitivity, and Windows drive-letter workspaces all passed only by construction. * test(cli): pin the distro-case fold from the CLI side The negative-only case passed identically with the fold broken. * fix(cli): name the WSL distro from the invocation cwd when the env is absent WSL_DISTRO_NAME only reaches the CLI if interop forwards it across the PowerShell bridge, which nothing in the launcher guarantees. ORCA_CLI_CWD is set explicitly and its UNC form already names the distro. * test(cli): match the launcher's real cwd spelling and fix an over-claim wslpath -w emits a backslash UNC path; the fallback test now uses that shape. The aliasing test's comment described a state the || guard makes unreachable. * refactor(cli): spell the WSL rewrite with the shared toWindowsWslPath helper src/shared/wsl-paths.ts already owns "absolute Linux path in a known distro -> its Windows form" and has five production callers; the handler hand-rolled a fourth copy of the UNC template. Behavior is identical under the UNC-root guard, and passing distro as a real argument makes the null check a compile error rather than an untested branch. * test(cli): drop a WSL case that pins the guard shape and kills no mutant Deleting the distro null check left the case green — it asserts the same passthrough as 'does not rewrite when the CLI is not running under WSL'. The check is now enforced by the compiler instead. * chore: keep WSL path fix scoped --------- Co-authored-by: Brennan Benson <79079362+brennanb2025@users.noreply.github.com> --- src/cli/handlers/file-absolute-paths.test.ts | 172 ++++++++++++++++++- src/cli/handlers/file.ts | 35 +++- 2 files changed, 204 insertions(+), 3 deletions(-) diff --git a/src/cli/handlers/file-absolute-paths.test.ts b/src/cli/handlers/file-absolute-paths.test.ts index aeeda196e8f..267d014762c 100644 --- a/src/cli/handlers/file-absolute-paths.test.ts +++ b/src/cli/handlers/file-absolute-paths.test.ts @@ -1,4 +1,4 @@ -import { beforeEach, describe, expect, it, vi } from 'vitest' +import { afterEach, beforeEach, describe, expect, it, vi } from 'vitest' const callMock = vi.fn() @@ -39,11 +39,18 @@ describe('absolute file CLI paths', () => { vi.restoreAllMocks() callMock.mockReset() process.exitCode = undefined + // Why: a contributor running this suite inside WSL inherits a real + // WSL_DISTRO_NAME, which would flip the rewrite on for every case below. + vi.stubEnv('WSL_DISTRO_NAME', '') vi.spyOn(console, 'log').mockImplementation(() => {}) vi.spyOn(console, 'error').mockImplementation(() => {}) }) - it('reproduces the issue positional WSL command without invalid_relative_path', async () => { + afterEach(() => { + vi.unstubAllEnvs() + }) + + it('reproduces the issue positional command without invalid_relative_path', async () => { const issuePath = '/root/orca/workspaces/xxx/xxx/xxx.ts' callMock.mockImplementation(async (method: string, params: { relativePath?: string }) => { if (method === 'worktree.list') { @@ -78,6 +85,167 @@ describe('absolute file CLI paths', () => { }) }) + describe('WSL UNC worktree roots', () => { + const uncRoot = '//wsl.localhost/Ubuntu/root/orca/workspaces/xxx' + + function mockWorktreeShow(rootPath: string): void { + queueFixtures( + callMock, + okFixture('req_show', { worktree: buildWorktree(rootPath, 'feature') }), + okFixture('req_open', { + worktree: 'wt-1', + relativePath: 'xxx/xxx.ts', + kind: 'text', + opened: true + }) + ) + } + + function expectOpenedWith(relativePath: string): void { + expect(process.exitCode).toBeUndefined() + expect(callMock).toHaveBeenNthCalledWith(2, 'files.open', { + worktree: 'id:wt-1', + relativePath + }) + } + + async function openPath(path: string, cwd = '/tmp'): Promise { + await main(['file', 'open', '--path', path, '--worktree', 'id:wt-1'], cwd) + } + + it('relativizes a Linux path typed inside the distro against the UNC root', async () => { + vi.stubEnv('WSL_DISTRO_NAME', 'Ubuntu') + mockWorktreeShow(uncRoot) + + await openPath('/root/orca/workspaces/xxx/xxx/xxx.ts') + + expectOpenedWith('xxx/xxx.ts') + }) + + it('relativizes against a legacy backslash wsl$ root', async () => { + vi.stubEnv('WSL_DISTRO_NAME', 'Ubuntu') + mockWorktreeShow('\\\\wsl$\\Ubuntu\\root\\orca\\workspaces\\xxx') + + await openPath('/root/orca/workspaces/xxx/xxx/xxx.ts') + + expectOpenedWith('xxx/xxx.ts') + }) + + it('does not double-prefix a UNC path the user already typed', async () => { + vi.stubEnv('WSL_DISTRO_NAME', 'Ubuntu') + mockWorktreeShow(uncRoot) + + await openPath(`${uncRoot}/xxx/xxx.ts`) + + expectOpenedWith('xxx/xxx.ts') + }) + + // Why: backslash is a legal Linux filename character, but reads as a separator + // once the path is UNC — rewriting `a\b.ts` would open `a/b.ts` instead. + it('leaves a Linux path containing a backslash for the runtime guard', async () => { + vi.stubEnv('WSL_DISTRO_NAME', 'Ubuntu') + mockWorktreeShow(uncRoot) + + await openPath('/root/orca/workspaces/xxx/a\\b.ts') + + expectOpenedWith('/root/orca/workspaces/xxx/a\\b.ts') + }) + + it('leaves a Linux path from another distro for the runtime guard', async () => { + vi.stubEnv('WSL_DISTRO_NAME', 'Debian') + mockWorktreeShow(uncRoot) + + await openPath('/root/orca/workspaces/xxx/xxx/xxx.ts') + + expectOpenedWith('/root/orca/workspaces/xxx/xxx/xxx.ts') + }) + + // Why: WSL_DISTRO_NAME is also set for a plain Linux CLI inside the distro, where + // roots are POSIX;

Both title and description switch on status.reason with no runtime guard, so a newer host publishing a fifth reason matched nothing and returned undefined. FolderPathStatusIndicator's `!title` check then dropped the whole indicator, and a broken folder workspace rendered as healthy -- worse than the blank toast #15002 fixed, because there the warning was empty and here it is gone. Guard before each switch, the shape #15002 landed. A default: arm is not available: the type-aware config sets allowDefaultCaseForExhaustiveSwitch:false and rejects one with switch-exhaustiveness-check. Extract that guard into isHandledWireDiscriminant instead of hand-writing a third and fourth copy, and move #15002's two bespoke guards onto it. It takes unknown and checks typeof before Object.hasOwn -- hasOwn coerces its key, so a host that widened the field to an array sends ['missing'], which a hasOwn-only guard admits before the switch drops it straight back out. That was the P1 found in review on #15002; one implementation makes it structural instead of tribal. An unrecognized reason gets its own copy rather than reusing 'unavailable'. The unavailable remedy -- "Check the runtime or SSH connection and try again" -- is a false lead here: the host did check and reported the folder unusable, so retrying and inspecting a healthy connection wastes the user's time. Update Orca is the real remedy. Adding a fifth reason still fails typecheck in two places: TS2741 on the Record and TS2366 plus switch-exhaustiveness-check on both switches. --- .../rows/FolderPathStatusIndicator.test.tsx | 65 ++++++++++++++++ src/renderer/src/i18n/locales/en.json | 6 +- .../src/lib/browser-cookie-import-toast.ts | 15 +--- .../lib/folder-workspace-path-status.test.ts | 77 +++++++++++++++++++ .../src/lib/folder-workspace-path-status.ts | 35 ++++++++- src/shared/handled-wire-discriminant.test.ts | 34 ++++++++ src/shared/handled-wire-discriminant.ts | 15 ++++ 7 files changed, 232 insertions(+), 15 deletions(-) create mode 100644 src/renderer/src/components/sidebar/worktree-list/rows/FolderPathStatusIndicator.test.tsx create mode 100644 src/renderer/src/lib/folder-workspace-path-status.test.ts create mode 100644 src/shared/handled-wire-discriminant.test.ts create mode 100644 src/shared/handled-wire-discriminant.ts diff --git a/src/renderer/src/components/sidebar/worktree-list/rows/FolderPathStatusIndicator.test.tsx b/src/renderer/src/components/sidebar/worktree-list/rows/FolderPathStatusIndicator.test.tsx new file mode 100644 index 00000000000..cb9c608dff6 --- /dev/null +++ b/src/renderer/src/components/sidebar/worktree-list/rows/FolderPathStatusIndicator.test.tsx @@ -0,0 +1,65 @@ +// @vitest-environment happy-dom + +import { renderToStaticMarkup } from 'react-dom/server' +import { describe, expect, it } from 'vitest' +import { TooltipProvider } from '@/components/ui/tooltip' +import type { FolderWorkspacePathStatus } from '../../../../../../shared/folder-workspace-path-status' +import { FolderPathStatusIndicator } from './FolderPathStatusIndicator' + +// Why: the status is cast, not decoded, off the runtime RPC wire, so a newer host really can put a +// reason this build has never heard of on the wire; the cast at the boundary is the point. +function renderIndicator(reason: unknown): string { + const status = { + path: '/srv/scans', + exists: false, + reason + } as unknown as FolderWorkspacePathStatus + return renderToStaticMarkup( + + + + ) +} + +describe('FolderPathStatusIndicator', () => { + it('marks a folder missing for a declared reason', () => { + const markup = renderIndicator('missing') + + expect(markup).toContain('aria-label="Folder not found"') + expect(markup).toContain('text-destructive') + }) + + // Why: losing the marker is worse than an imprecise one — the sidebar then renders a broken + // folder workspace as healthy, with nothing to click and nothing to read. + it('still renders the marker when a newer host sends an undeclared reason', () => { + const markup = renderIndicator('permission-denied') + + expect(markup).not.toBe('') + expect(markup).toContain('aria-label="') + expect(markup).not.toContain('aria-label=""') + // Why: an imprecise label must not borrow a specific cause it cannot substantiate. + expect(markup).not.toContain('aria-label="Folder not found"') + // Why: unknown is not confirmed stale, so the marker stays neutral rather than destructive. + expect(markup).toContain('text-muted-foreground') + }) + + it('still renders the marker when the wire carries a non-string reason', () => { + const markup = renderIndicator(['missing']) + + expect(markup).not.toBe('') + expect(markup).toContain('aria-label="') + expect(markup).not.toContain('aria-label=""') + // Why: hasOwn coerces its key, so ['missing'] must not be read as the confirmed-stale 'missing'. + expect(markup).not.toContain('aria-label="Folder not found"') + }) + + it('renders nothing for a healthy folder', () => { + const markup = renderToStaticMarkup( + + + + ) + + expect(markup).toBe('') + }) +}) diff --git a/src/renderer/src/i18n/locales/en.json b/src/renderer/src/i18n/locales/en.json index d68878909e8..2d62d5f1858 100644 --- a/src/renderer/src/i18n/locales/en.json +++ b/src/renderer/src/i18n/locales/en.json @@ -697,13 +697,15 @@ "missing": "Folder not found", "notDirectory": "Path is not a folder", "ambiguousConnection": "Cannot determine connection", - "unavailable": "Cannot check folder" + "unavailable": "Cannot check folder", + "unrecognized": "Folder is not usable" }, "description": { "missing": "Orca cannot find {{path}}.

The route called preventDefault() before checking whether it owned the session. The patched xterm treats that cancellation as "someone else will deliver this" and skips its own triggerDataEvent, so a route installed mid-composition — the connection effect re-runs, a reconnect swaps the transport, StrictMode remounts — suppressed the insertion and then returned without delivering anything. The commit vanished. Ownership is now decided first; preventDefault stays for sessions the route does own, including the ones it deliberately drops after a transport swap, since that drop is its decision to make. Pending-composition state was a bare per-element count, so a waiter could only ask "is anything composing", not "is what I was waiting for still composing". A composition the user starts after pressing Enter is behind that Enter, not in front of it, but it kept the count non-zero and held the newline anyway — `한` Enter `글` reaching the terminal as `한글\n`. The count is now reference-counted per session id, and the deferred send snapshots the sessions open when it starts and waits only for those. Reference counts rather than a set, so two overlapping routes owning the same session cannot clear each other's pending state.

Two handlers acted on it: - right-panel-comment-composer: Cmd/Ctrl+Enter posted the comment while the last syllable was still composing, so it went out truncated. - RichMarkdownSearchBar: Enter ran replace-current, mutating the document from a keystroke aimed at the candidate list; Escape closed the bar instead of letting the IME cancel the composition. Same in the find field. Guard all three with the existing isImeCompositionKeyDown helper, matching the rename and title inputs already on it. The held modifier does not change ownership: a composing Ctrl+Enter is still the IME's keydown, which is why useImeEnterGestureOwnership also owns it and only lets the post-compositionend redispatch chord through.

A rejected send restored a TRIMMED composer. #14665 reassigned `text` to `text.trimEnd()` at the top of `sendMessage` and then used that one value for both the bytes on the wire and the composer restore, so a rejection put back less than the user typed. The draft and the payload are now separate values: `draftText` is what the user typed and is what `clearDraftForSend` / `restoreRejectedDraft` see; only the transported `text` is trimmed. 2. Sends issued during hydration were stranded forever. #14665 persisted `glueBaselineTrusted: false` on any send captured while the transcript was still loading and never cleared it, so that send could never retire and stood as a permanent glue barrier for its neighbours. A hydration-time baseline is now a placeholder (`baselineResolved: false`) that the first authoritative read rebases onto real rows, ordinals included, instead of a permanent disqualification. That is STA-4492. The intended behavior is unchanged: one transcript user turn retires a run of 2+ adjacent text-only pending sends only when it exactly spells their normalized concatenation, every send is bounded by its OWN transcript tail, and exact landings, image echoes and unresolved tails stay barriers. No wire change: `baselineResolved` and the baseline tail are client-local React state in `pendingBySession` and are never exchanged with a host. The only client->host difference is trailing whitespace no longer being written onto the agent's input line, over the existing `terminal.send` params. Refs STA-4482, STA-4492. Original PR #14665, revert #14819. * fix(mobile-native-chat): let the untrimmed draft reach the send seam The composer sent `value.trimEnd()`, so the raw draft never reached `sendMessage` and a rejected send still handed back a trimmed composer — the split of `draftText` from the transported `text` had nothing to restore. Pass the draft through; the seam already owns the wire trim. Also pins the array-identity contract of `retireLandedMobileNativeChatPending`: the drafts effect early-outs on `next === current`, and nothing tested it. * docs(mobile-native-chat): name the hydration rebase's residual ambiguity * fix(mobile-native-chat): stop the hydration rebase stranding a send on its own echo Rebasing recounted the send's ordinal against the first authoritative read. That read can already carry the send's own echo — a re-subscribe after a tab switch or reconnect returns whatever exists now — so the ordinal landed one past anything the transcript could supply. The bubble never cleared, it stayed a live segment at the head of its run so no later pair could glue either, and `earlierOutstanding` carried the inflation onto the next send of the same text. Only the tail needs recovering; the ordinal was already counted against an empty transcript, which is right for "no history was known". A caption-less image echo keeps its captured tail, since it counts turns after it. `baselineResolved` also has to mean "captured against a settled read", not merely "not loading": a read that failed hands back an empty list that reads as an empty conversation, and the null tail then let any row the successful read finally brought glue-retire those sends. * test(mobile-native-chat): pin that a resolved hydration send leaves its run glue-capable A held send sits as a live segment at the head of its run, so the cursor can never reach a later pair — the stuck bubble takes the whole feature down with it. Goes red against the ordinal recount. * fix(mobile-native-chat): pin an image echo that captured no tail, and require the settled flag A caption-less image echo keeps its captured tail because it counts image turns after it — but a send issued before any history was known captured null, which counts from the top of the transcript. An old image turn then claimed the send and bound the user's fresh photo to it, leaving the just-sent turn with no preview. A null tail is not a boundary worth preserving, so pin those too. `transcriptSettled` was optional and defaulted to the gate it replaced, so any caller that omitted it silently got the pre-fix behaviour. Required now, and threaded through every harness. * fix(mobile-native-chat): stop an unbounded send claiming an image turn already in the read The image-preview pass runs before the rebase, so a send captured with no boundary matched any image turn the settled read carried — binding the user's freshly attached photo to an old one and retiring the bubble through landedImagePendingIds, which short-circuits the retirement path entirely. Pinning the tail in the rebase could not help: the claim was already made. Such an entry now waits one tick and claims against a real tail. * fix(mobile-native-chat): never move a boundary the send already captured An unsettled read still shows this session's own retained history — a reconnect or a failed read keeps the conversation on screen rather than blanking it — so sends made across one already own a correct tail. The rebase overwrote it with the tail of the read that followed, which sits at or after their own glued row, so `turn.index <= segment.tail` rejected every turn and the pair stayed queued for the session, blocking every later pair in the run. Pin only a send that captured no tail at all. A captioned image echo is now left alone entirely: it binds its preview by an ordinal counted over the whole transcript, so supplying a tail without recounting left it matching nothing, forever. * fix(mobile-native-chat): supply a boundary only to a text-bearing send An image echo reconciles by counting turns AFTER its tail and has no other retirement path, so the tail supplied from a read that already carried its own echo excluded the very row it was waiting for: the "Queued" photo bubble stuck for the life of the session and the transcript row rendered as bare marker text with no photo. A regression against main, and against the earlier revision of this fix that pinned only captioned echoes. The glue matcher is the only consumer a supplied tail helps. Everything that reconciles relative to its own tail keeps whatever it captured. * fix(mobile-native-chat): stop one unmatchable send freezing glue for the session The match cursor only advanced on a hit, so a head that could never match — a pair whose glued row arrived with the read, or a send the count pass claimed against an older row — froze the run behind it and every later rapid pair became permanently unretirable. Two cases previously disclosed as bounded were not bounded at all. Slide past a non-matching head, keeping the cursor monotonic so a later turn can never take a send an earlier one claimed. The slide widens the search, so a span cap keeps the work linear in the run length instead of quadratic; the existing budget test now asserts that bound rather than the old one it silently broke. Re-fuzzed at 250k seeds: the boundary guarantee still holds. Also corrects a comment that claimed the preview-pass filter made a photo claim against a real tail. It does not — an image echo keeps whatever tail it captured, so a caption-less photo can still bind to an older photo turn, as on main. * fix(mobile-native-chat): stop the span cap stranding a long glued run Capping each match attempt at 8 segments did not truncate a longer glue, it rejected it outright: a row spelling 9+ sends exhausted the loop without reaching the end of the text and returned zero, so none of the nine retired — and each stuck send then inflated `earlierOutstanding` for the next send of the same text. Nothing bounds how many sends pile onto the agent's input line; accumulation ends when the agent accepts input again, not at any fixed count. One inspection budget now covers the whole slide instead. The first attempt spans the entire run and always fits, so a genuine glue is never truncated; only a run of identical prefix-matching sends can exhaust the budget, which is exactly the case that should be cheap. The in-flight attempt may overshoot the remainder — that is what makes the guarantee hold — so the budget test asserts the real ceiling. Re-fuzzed at 250k seeds with runs past the budget. --- .../session/MobileNativeChatComposer.test.ts | 8 +- .../src/session/MobileNativeChatComposer.tsx | 4 +- ...obile-native-chat-pending-baseline.test.ts | 164 ++++++++ .../mobile-native-chat-pending-baseline.ts | 53 +++ .../mobile-native-chat-pending-echo.ts | 7 + ...ile-native-chat-pending-retirement.test.ts | 323 ++++++++++++++++ .../mobile-native-chat-pending-retirement.ts | 173 +++++++++ .../use-mobile-native-chat-controller.test.ts | 3 +- .../use-mobile-native-chat-controller.ts | 3 +- ...e-native-chat-drafts-glued-pending.test.ts | 359 ++++++++++++++++++ ...le-native-chat-drafts-launch-draft.test.ts | 7 +- .../use-mobile-native-chat-drafts.test.ts | 7 +- .../session/use-mobile-native-chat-drafts.ts | 61 +-- ...se-mobile-native-chat-message-send.test.ts | 65 +++- .../use-mobile-native-chat-message-send.ts | 13 +- 15 files changed, 1204 insertions(+), 46 deletions(-) create mode 100644 mobile/src/session/mobile-native-chat-pending-baseline.test.ts create mode 100644 mobile/src/session/mobile-native-chat-pending-baseline.ts create mode 100644 mobile/src/session/mobile-native-chat-pending-retirement.test.ts create mode 100644 mobile/src/session/mobile-native-chat-pending-retirement.ts create mode 100644 mobile/src/session/use-mobile-native-chat-drafts-glued-pending.test.ts diff --git a/mobile/src/session/MobileNativeChatComposer.test.ts b/mobile/src/session/MobileNativeChatComposer.test.ts index 1d1b0288467..3c8afe2cefd 100644 --- a/mobile/src/session/MobileNativeChatComposer.test.ts +++ b/mobile/src/session/MobileNativeChatComposer.test.ts @@ -84,7 +84,9 @@ describe('MobileNativeChatComposer', () => { await act(async () => sendButton().props.onPress()) -

On Windows any exclusive lock — Defender real-time scanning, a backup agent, a sync client — makes every read of that marker fail with EBUSY, and the background rate-limit poll runs every 15 minutes plus once at every app start. Root cause: the ownership gate answered two very different questions through one channel. "This home is not ours" (a successful observation that failed a trust check) and "we could not read it" both surfaced as a throw, which the caller flattened to null, which three call sites took as proof the home was untrustworthy and wrote activeCodexManagedAccountId: null. Refusing to USE an unverified home is correct. Erasing the user's account selection because a file was briefly locked is not. The gate now returns a tri-state verdict. `untrusted` comes only from a proven trust failure or a definitive ENOENT/ENOTDIR where absence is itself the verdict; every other filesystem exception is `indeterminate`. Only `untrusted` may touch persisted state. Because `null` already meant "fall through to the system default" on both the launch and poll paths, not-clearing on its own would have run a DIFFERENT account behind a UI still showing the selected one. So the refusal needed real channels rather than a sentinel: - the poll returns an explicit skip; returning null would not have skipped at all, since the fetcher maps null to ~/.codex and would have spawned a token-refreshing app-server inside the user's real credential home - pane launch throws a typed temporary-unavailability error that both PTY implementations convert into a clean refusal with a retry message, including the re-resolution after the async auth-readiness wait - automatic session resume resolves the selected home eagerly, so an unreadable account can no longer be silently replaced by another one in the ranking - config-sync status reports a distinct managed-home-unavailable stall instead of "synced", with a bounded renderer retry so it clears on its own Also fixes the ticket's second symptom. The status bar's Sign in button called a re-auth that captured the selection before login and restored it after, so re-authenticating a deselected account restored `null` — a successful login that left the account inactive, with no success toast to distinguish it from failure. It now activates the account it just signed in, but only when the pre-login selection was empty, so it cannot silently switch accounts for multi-account users, and it runs the same restart prompt an explicit switch does. No retry or grace window inside the synchronous gate: it runs on the Electron main process in a loop over accounts, so a sleep there would freeze the UI. Recovery is simply the next readable evaluation. The WSL lane has the same class of defect, including one path that deletes a credential mirror. It is pre-existing, unreachable from these host code paths, and deliberately left for its own change; the host clearing sites cannot reach a WSL account because getSelfContainedManagedHostAccount excludes them.
