* feat: auto-poll Docker capabilities while Docker tab is active
When the Docker tab is visible and hasDocker is not yet true,
poll refreshCapabilities() at the process refresh interval.
Stop polling once hasDocker becomes true, or when switching
to a different tab.
* fix: use resolvedTab instead of activeTab for Docker auto-poll condition
The auto-poll useEffect condition used activeTab, which stays stale
when Docker becomes unavailable. Changed to resolvedTab which reflects
the actual displayed tab. Also updated the dep array.
* fix: replace setInterval with setTimeout recursion in Docker tab probe
Replace setInterval-based polling with setTimeout recursion in the Docker
tab capability probe effect. This ensures the next probe only starts after
the previous one finishes, avoiding overlapping probes when SSH timeout
exceeds the polling interval.
- Add dockerPollTimerRef to track the timeout handle
- Use async pollOnce() that awaits refreshCapabilities() before scheduling next
- Use cancelled flag in cleanup to prevent scheduling after unmount
- Keep same dependency array for correctness
* fix: stabilize docker poll timer by using useRef for refreshCapabilities
refreshCapabilities() can return a new reference on every render, causing
the useEffect to re-run on every render — cleanup cancels the polling timer,
then the effect immediately calls pollOnce(), effectively bypassing the
configured timeout interval.
Fix: store refreshCapabilities in a useRef (refreshRef), use
refreshRef.current() inside pollOnce(), and replace refreshCapabilities
with refreshRef in the useEffect dependency array.
Closes #PR1456 Codex P2 review item.
* fix: delay auto-poll first probe by one interval to avoid overlap with tab-switch probe
When switching to the Docker tab, two mechanisms were triggering probes:
1. tab-switch effect (line 67-76): immediate probe via refreshCapabilities()
2. auto-poll effect: pollOnce() executing immediately on mount
This caused duplicate probes that waste SSH channel resources.
Fix: pollOnce() no longer fires on mount. Instead, the effect schedules the
first probe with setTimeout(pollOnce, capabilitiesTtlMs), so the first probe
happens after one full interval. Subsequent probes continue at interval pace
via the setTimeout recursion in pollOnce itself.
The tab-switch effect still fires the immediate probe (the correct one),
so responsiveness on tab switch is preserved.
* fix: reset cancelledRef in effect body to prevent permanent stalling of Docker polling
The cancelledRef was set to true in the cleanup function when dependencies
changed, but never reset when the effect re-ran. This caused pollOnce to
always early-return on subsequent timer ticks, permanently halting
Docker capability probing after the first dependency change.
* fix(system-manager): replace cancelledRef with closure variables for per-effect cancellation
Each effect generation now has its own and closure
variables instead of shared / . This
prevents stale probes from surviving cleanup when the panel hides and
re-shows (Codex P2 review).
* fix: wrap refreshCapabilities in try/catch to keep polling on exception
If refreshCapabilities throws (instead of returning {success: false}),
the await would exit pollOnce without scheduling the next setTimeout,
silently killing Docker auto-detection polling.
* fix: add in-flight probe guard to prevent tab-switch and auto-poll concurrent probes
Add probingRef to track whether a capabilities probe is already in-flight.
- Tab-switch effect for Docker branch checks probingRef before starting a new probe
- Auto-poll pollOnce checks probingRef at entry and sets/clears it around the actual probe
- Tmux branch left unchanged as it has no auto-poll overlap risk
* fix: re-schedule next poll timer when probe is in-flight
When probingRef.current is true (tab-switch probe still running),
pollOnce was returning early without scheduling the next timer,
causing auto-poll to stop permanently afterward.
Now it schedules the next poll within the interval and returns,
so the polling loop keeps running until a slot where no probe is
active.
* fix: convert comments to ASCII-only English
- Line 105: translate Chinese comment to 'probe is in-flight, reschedule for next cycle'
- Line 113: replace em dash (U+2014) with ASCII dash
* feat: session inline rename, closeSession shortcut, pane zoom
* fix: sidebar inline rename with local state
* fix: add sessionDisplayName to terminalPropsAreEqual comparator
The Terminal component is wrapped with React.memo(…, terminalPropsAreEqual),
but the comparator was missing a check for sessionDisplayName. After renaming
a session, the pane title bar would show the old name until some other prop
changed and triggered a re-render.
Add prev.sessionDisplayName === next.sessionDisplayName to the comparator
so that display name changes cause the Terminal to re-render immediately.
* fix: add onStartSessionRename to TerminalLayerWorkspaceSection ctx destructuring and TerminalPanesHost props
* fix: add toggleWorkspaceViewMode to executeHotkeyActionImpl destructuring
The togglePaneZoom handler calls toggleWorkspaceViewMode() but it
wasn't destructured from getCtx(), causing a ReferenceError at runtime.
* fix: restore truncated ctx object in TerminalView render call
The TerminalView ctx object literal on line 1265 was truncated to
'showSele...' due to an editing tool truncation bug, causing
Parsing error: ',' expected on npm run lint / tsc --noEmit.
Restored the missing fields from the base commit:
showSelectionAIAction, snippets, status, statusDotTone, sudoHintRef,
sudoHintText: t("terminal.sudoHint.pressEnter"), t, termRef,
terminalBackend, terminalContextActions, terminalCwdTracker,
terminalPreviewVars, terminalSettings, timeLeft, toast, zmodem
Kept the PR's new additions (isVisible, onRename, sessionDisplayName)
intact.
* fix: add toggleWorkspaceViewMode to executeHotkeyAction context and add terminal.menu.rename translations
- Add toggleWorkspaceViewMode to the context getter in executeHotkeyAction (App.tsx)
- Add terminal.menu.rename translation for en (Rename), zh-CN (重命名), ru (Переименовать)
* fix: validate focusedSessionId before closing in closeSession hotkey
When closeSession hotkey fires, workspace.focusedSessionId may reference
a session that was already closed by another trigger (e.g., mouse click
on tab close button). Collect alive session IDs from the workspace root
and fall back to the first living pane if the stored focusedSessionId
is stale.
* fix(auto-poll): check useSessionCapabilities probing state in pollOnce
When auto-poll timer fires before the initial probe (from
useSessionCapabilities) completes, probingRef.current is still false
because the initial probe doesn't set it — causing a second overlapping
probe.
Add check so that any in-flight probe from any path
(initial/auto-poll/tab-switch) prevents auto-poll overlap.

* fix(system): increase process list limit and improve Docker detection for openEuler
Root cause analysis for issue #1453:
1. Process list limit too low: The `head -n 200` pipeline capped the process
list at 200 entries, causing the displayed count to mismatch `ps aux | wc -l`
on systems with many processes (common on openEuler servers with Docker,
databases, etc.). Increased limit from 200 to 2000 for both Linux/SSH
(ps) and Windows (PowerShell) backends.
2. Docker detection failure on openEuler 24.03: The capability probe only
relied on `docker info >/dev/null 2>&1`, which can fail even when Docker
is running due to:
- SSH exec channel environment differences vs interactive shell
- Docker socket permission variations in non-interactive sessions
- Different socket path configurations on openEuler
Added a fallback: if `docker info` fails but the Docker socket exists at
`/var/run/docker.sock`, Docker is still detected as available. This
matches the behavior of other SSH terminal clients.
* fix(system): also add Docker socket fallback to fallback probe script for consistency
* fix(system): remove hardcoded process list limit, add capability probe TTL, auto-reprobe on tab switch
Three remaining issues from PR #1455:
1. Remove hardcoded `head -n 2000` / `Select-Object -First 2000`
process list limits — virtual list handles rendering efficiently.
2. Add 60-second TTL to sessionCapabilitiesStore cache. `get()` returns
undefined for expired entries, forcing re-probe on next access.
`set()` always refreshes `probedAt`. Export CAPABILITIES_TTL_MS
constant for future tuning.
3. Auto-trigger capability re-probe when switching to Docker/Tmux tab
whose tool was previously reported unavailable — handles the case
where Docker/Tmux was installed after the last probe.
* fix: replace Docker socket -S check with -r for permission accuracy; sync capabilities TTL with process refresh interval
- Change [ -S /var/run/docker.sock ] to [ -r /var/run/docker.sock ] in
both the main capability probe script and the POSIX fallback (electron bridge).
-r verifies the socket exists AND the current user has read permission,
preventing false-positive Docker detection that leads to failed Docker ops.
- Remove hardcoded CAPABILITIES_TTL_MS (60s) from sessionCapabilitiesStore.
Store now computes expiresAt internally in set(ttlMs) and checks it in get()
without requiring a parameter at call sites.
- useSessionCapabilities and useSystemCapabilitiesWarmup accept a
capabilitiesTtlMs parameter derived from
terminalSettings.systemManagerProcessRefreshInterval (default 3s → 3 000ms).
- SystemManagerSidePanel passes the TTL from terminalSettings to the hook.
- TerminalLayerTabBridge passes TTL from stableRef settings to warmup hook.
- Fix missing refreshCapabilities destructuring in SystemManagerSidePanel.
* fix: restore process list safety cap (head -n 2000 / -First 2000)
Codex review flagged that removing the process list cap entirely could cause
timeout/maxBuffer issues on process-dense hosts. Restore head -n 2000 (POSIX)
and -First 2000 (Windows) as a safety guard with comments clarifying this is
NOT a functional limit — monitored processes still show accurate metrics.
* fix: hoist useRef/useEffect before early returns to fix React hook order violation
The useRef and useEffect for tab-switch re-probe were placed after early returns
for missing/disconnected sessions. When a session later connects, React discovers
new hooks that weren't registered before, causing hook order violation crashes.
Moved both hooks immediately after the resolvedTab computation, before any early
return path, satisfying React's Rules of Hooks.
* fix: change Docker detection from OR to AND (CLI + socket)
Both capability detection and fallback probe now require:
- docker CLI is on PATH (command -v docker)
- docker.sock is readable ([ -r /var/run/docker.sock ])
Previously used OR logic (docker info || socket readable),
which could report hasDocker=true even when docker CLI
was unavailable (e.g., non-login SSH shell).
Fixes#1453
* fix(system-monitor): prefer docker info, fallback to CLI+socket
Co-authored-by: Codex <codex@anthropic.com>
Changes:
- Line 12: Replace strict CLI+socket check with docker info first,
falling back to CLI+socket check only if docker info fails.
- Line 139: Same fix in the fallback probe script.
This handles DOCKER_HOST, Docker contexts, and rootless Docker.
* fix: notify subscribers when TTL expires in sessionCapabilitiesStore.get()
When capabilitiesBySessionId.get() finds an expired entry, it deletes the
entry but did not notify session subscribers. This caused components to
stale capabilities until the next successful set() call.
Now get() calls notifySession() on expiry, matching the notification
behavior already present in delete().
