* fix(proxy): merge static and provider entries in snapshot; fix Virtuoso viewport height
* fix(proxy-groups): restrict reduced-height viewport to chain-mode column
* refactor(profiles): introduce a state machine
* refactor:replace state machine with reducer
* refactor:introduce a profile switch worker
* refactor: hooked up a backend-driven profile switch flow
* refactor(profile-switch): serialize switches with async queue and enrich frontend events
* feat(profiles): centralize profile switching with reducer/driver queue to fix stuck UI on rapid toggles
* chore: translate comments and log messages to English to avoid encoding issues
* refactor: migrate backend queue to SwitchDriver actor
* fix(profile): unify error string types in validation helper
* refactor(profile): make switch driver fully async and handle panics safely
* refactor(cmd): move switch-validation helper into new profile_switch module
* refactor(profile): modularize switch logic into profile_switch.rs
* refactor(profile_switch): modularize switch handler
- Break monolithic switch handler into proper module hierarchy
- Move shared globals, constants, and SwitchScope guard to state.rs
- Isolate queue orchestration and async task spawning in driver.rs
- Consolidate switch pipeline and config patching in workflow.rs
- Extract request pre-checks/YAML validation into validation.rs
* refactor(profile_switch): centralize state management and add cancellation flow
- Introduced SwitchManager in state.rs to unify mutex, sequencing, and SwitchScope handling.
- Added SwitchCancellation and SwitchRequest wrappers to encapsulate cancel tokens and notifications.
- Updated driver to allocate task IDs via SwitchManager, cancel old tokens, and queue next jobs in order.
- Updated workflow to check cancellation and sequence at each phase, replacing global flags with manager APIs.
* feat(profile_switch): integrate explicit state machine for profile switching
- workflow.rs:24 now delegates each switch to SwitchStateMachine, passing an owned SwitchRequest.
Queue cancellation and state-sequence checks are centralized inside the machine instead of scattered guards.
- workflow.rs:176 replaces the old helper with `SwitchStateMachine::new(manager(), None, profiles).run().await`,
ensuring manual profile patches follow the same workflow (locking, validation, rollback) as queued switches.
- workflow.rs:180 & 275 expose `validate_profile_yaml` and `restore_previous_profile` for reuse inside the state machine.
- workflow/state_machine.rs:1 introduces a dedicated state machine module.
It manages global mutex acquisition, request/cancellation state, YAML validation, draft patching,
`CoreManager::update_config`, failure rollback, and tray/notification side-effects.
Transitions check for cancellations and stale sequences; completions release guards via `SwitchScope` drop.
* refactor(profile-switch): integrate stage-aware panic handling
- src-tauri/src/cmd/profile_switch/workflow/state_machine.rs:1
Defines SwitchStage and SwitchPanicInfo as crate-visible, wraps each transition in with_stage(...) with catch_unwind, and propagates CmdResult<bool> to distinguish validation failures from panics while keeping cancellation semantics.
- src-tauri/src/cmd/profile_switch/workflow.rs:25
Updates run_switch_job to return Result<bool, SwitchPanicInfo>, routing timeout, validation, config, and stage panic cases separately. Reuses SwitchPanicInfo for logging/UI notifications; patch_profiles_config maps state-machine panics into user-facing error strings.
- src-tauri/src/cmd/profile_switch/driver.rs:1
Adds SwitchJobOutcome to unify workflow results: normal completions carry bool, and panics propagate SwitchPanicInfo. The driver loop now logs panics explicitly and uses AssertUnwindSafe(...).catch_unwind() to guard setup-phase panics.
* refactor(profile-switch): add watchdog, heartbeat, and async timeout guards
- Introduce SwitchHeartbeat for stage tracking and timing; log stage transitions with elapsed durations.
- Add watchdog in driver to cancel stalled switches (5s heartbeat timeout).
- Wrap blocking ops (Config::apply, tray updates, profiles_save_file_safe, etc.) with time::timeout to prevent async stalls.
- Improve logs for stage transitions and watchdog timeouts to clarify cancellation points.
* refactor(profile-switch): async post-switch tasks, early lock release, and spawn_blocking for IO
* feat(profile-switch): track cleanup and coordinate pipeline
- Add explicit cleanup tracking in the driver (`cleanup_profiles` map + `CleanupDone` messages) to know when background post-switch work is still running before starting a new workflow. (driver.rs:29-50)
- Update `handle_enqueue` to detect “cleanup in progress”: same-profile retries are short-circuited; other requests collapse the pending queue, cancelling old tokens so only the latest intent survives. (driver.rs:176-247)
- Rework scheduling helpers: `start_next_job` refuses to start while cleanup is outstanding; discarded requests release cancellation tokens; cleanup completion explicitly restarts the pipeline. (driver.rs:258-442)
* feat(profile-switch): unify post-switch cleanup handling
- workflow.rs (25-427) returns `SwitchWorkflowResult` (success + CleanupHandle) or `SwitchWorkflowError`.
All failure/timeout paths stash post-switch work into a single CleanupHandle.
Cleanup helpers (`notify_profile_switch_finished` and `close_connections_after_switch`) run inside that task for proper lifetime handling.
- driver.rs (29-439) propagates CleanupHandle through `SwitchJobOutcome`, spawns a bridge to wait for completion, and blocks `start_next_job` until done.
Direct driver-side panics now schedule failure cleanup via the shared helper.
* tmp
* Revert "tmp"
This reverts commit e582cf4a65.
* refactor: queue frontend events through async dispatcher
* refactor: queue frontend switch/proxy events and throttle notices
* chore: frontend debug log
* fix: re-enable only ProfileSwitchFinished events - keep others suppressed for crash isolation
- Re-enabled only ProfileSwitchFinished events; RefreshClash, RefreshProxy, and ProfileChanged remain suppressed (they log suppression messages)
- Allows frontend to receive task completion notifications for UI feedback while crash isolation continues
- src-tauri/src/core/handle.rs now only suppresses notify_profile_changed
- Serialized emitter, frontend logging bridge, and other diagnostics unchanged
* refactor: refreshClashData
* refactor(proxy): stabilize proxy switch pipeline and rendering
- Add coalescing buffer in notification.rs to emit only the latest proxies-updated snapshot
- Replace nextTick with queueMicrotask in asyncQueue.ts for same-frame hydration
- Hide auto-generated GLOBAL snapshot and preserve optional metadata in proxy-snapshot.ts
- Introduce stable proxy rendering state in AppDataProvider (proxyTargetProfileId, proxyDisplayProfileId, isProxyRefreshPending)
- Update proxy page to fade content during refresh and overlay status banner instead of showing incomplete snapshot
* refactor(profiles): move manual activating logic to reducer for deterministic queue tracking
* refactor: replace proxy-data event bridge with pure polling and simplify proxy store
- Replaced the proxy-data event bridge with pure polling: AppDataProvider now fetches the initial snapshot and drives refreshes from the polled switchStatus, removing verge://refresh-* listeners (src/providers/app-data-provider.tsx).
- Simplified proxy-store by dropping the proxies-updated listener queue and unused payload/normalizer helpers; relies on SWR/provider fetch path + calcuProxies for live updates (src/stores/proxy-store.ts).
- Trimmed layout-level event wiring to keep only notice/show/hide subscriptions, removing obsolete refresh listeners (src/pages/_layout/useLayoutEvents.ts).
* refactor(proxy): streamline proxies-updated handling and store event flow
- AppDataProvider now treats `proxies-updated` as the fast path: the listener
calls `applyLiveProxyPayload` immediately and schedules only a single fallback
`fetchLiveProxies` ~600 ms later (replacing the old 0/250/1000/2000 cascade).
Expensive provider/rule refreshes run in parallel via `Promise.allSettled`, and
the multi-stage queue on profile updates completion was removed
(src/providers/app-data-provider.tsx).
- Rebuilt proxy-store to support the event flow: restored `setLive`, provider
normalization, and an animation-frame + async queue that applies payloads without
blocking. Exposed `applyLiveProxyPayload` so providers can push events directly
into the store (src/stores/proxy-store.ts).
* refactor: switch delay
* refactor(app-data-provider): trigger getProfileSwitchStatus revalidation on profile-switch-finished
- AppDataProvider now listens to `profile-switch-finished` and calls `mutate("getProfileSwitchStatus")` to immediately update state and unlock buttons (src/providers/app-data-provider.tsx).
- Retain existing detailed timing logs for monitoring other stages.
- Frontend success notifications remain instant; background refreshes continue asynchronously.
* fix(profiles): prevent duplicate toast on page remount
* refactor(profile-switch): make active switches preemptible and prevent queue piling
- Add notify mechanism to SwitchCancellation to await cancellation without busy-waiting (state.rs:82)
- Collapse pending queue to a single entry in the driver; cancel in-flight task on newer request (driver.rs:232)
- Update handle_update_core to watch cancel token and 30s timeout; release locks, discard draft, and exit early if canceled (state_machine.rs:301)
- Providers revalidate status immediately on profile-switch-finished events (app-data-provider.tsx:208)
* refactor(core): make core reload phase controllable, reduce 0xcfffffff risk
- CoreManager::apply_config now calls `reload_config_with_retry`, each attempt waits up to 5s, retries 3 times; on failure, returns error with duration logged and triggers core restart if needed (src-tauri/src/core/manager/config.rs:175, 205)
- `reload_config_with_retry` logs attempt info on timeout or error; if error is a Mihomo connection issue, fallback to original restart logic (src-tauri/src/core/manager/config.rs:211)
- `reload_config_once` retains original Mihomo call for retry wrapper usage (src-tauri/src/core/manager/config.rs:247)
* chore(frontend-logs): downgrade routine event logs from info to debug
- Logs like `emit_via_app entering spawn_blocking`, `Async emit…`, `Buffered proxies…` are now debug-level (src-tauri/src/core/notification.rs:155, :265, :309…)
- Genuine warnings/errors (failures/timeouts) remain at warn/error
- Core stage logs remain info to keep backend tracking visible
* refactor(frontend-emit): make emit_via_app fire-and-forget async
- `emit_via_app` now a regular function; spawns with `tokio::spawn` and logs a warn if `emit_to` fails, caller returns immediately (src-tauri/src/core/notification.rs:269)
- Removed `.await` at Async emit and flush_proxies calls; only record dispatch duration and warn on failure (src-tauri/src/core/notification.rs:211, :329)
* refactor(ui): restructure profile switch for event-driven speed + polling stability
- Backend
- SwitchManager maintains a lightweight event queue: added `event_sequence`, `recent_events`, and `SwitchResultEvent`; provides `push_event` / `events_after` (state.rs)
- `handle_completion` pushes events on success/failure and keeps `last_result` (driver.rs) for frontend incremental fetch
- New Tauri command `get_profile_switch_events(after_sequence)` exposes `events_after` (profile_switch/mod.rs → profile.rs → lib.rs)
- Notification system
- `NotificationSystem::process_event` only logs debug, disables WebView `emit_to`, fixes 0xcfffffff
- Related emit/buffer functions now safe no-op, removed unused structures and warnings (notification.rs)
- Frontend
- services/cmds.ts defines `SwitchResultEvent` and `getProfileSwitchEvents`
- `AppDataProvider` holds `switchEventSeqRef`, polls incremental events every 0.25s (busy) / 1s (idle); each event triggers:
- immediate `globalMutate("getProfiles")` to refresh current profile
- background refresh of proxies/providers/rules via `Promise.allSettled` (failures logged, non-blocking)
- forced `mutateSwitchStatus` to correct state
- original switchStatus effect calls `handleSwitchResult` as fallback; other toast/activation logic handled in profiles.tsx
- Commands / API cleanup
- removed `pub use profile_switch::*;` in cmd::mod.rs to avoid conflicts; frontend uses new command polling
* refactor(frontend): optimize profile switch with optimistic updates
* refactor(profile-switch): switch to event-driven flow with Profile Store
- SwitchManager pushes events; frontend polls get_profile_switch_events
- Zustand store handles optimistic profiles; AppDataProvider applies updates and background-fetches
- UI flicker removed
* fix(app-data): re-hook profile store updates during switch hydration
* fix(notification): restore frontend event dispatch and non-blocking emits
* fix(app-data-provider): restore proxy refresh and seed snapshot after refactor
* fix: ensure switch completion events are received and handle proxies-updated
* fix(app-data-provider): dedupe switch results by taskId and fix stale profile state
* fix(profile-switch): ensure patch_profiles_config_by_profile_index waits for real completion and handle join failures in apply_config_with_timeout
* docs: UPDATELOG.md
* chore: add necessary comments
* fix(core): always dispatch async proxy snapshot after RefreshClash event
* fix(proxy-store, provider): handle pending snapshots and proxy profiles
- Added pending snapshot tracking in proxy-store so `lastAppliedFetchId` no longer jumps on seed. Profile adoption is deferred until a qualifying fetch completes. Exposed `clearPendingProfile` for rollback support.
- Cleared pending snapshot state whenever live payloads apply or the store resets, preventing stale optimistic profile IDs after failures.
- In provider integration, subscribed to the pending proxy profile and fed it into target-profile derivation. Cleared it on failed switch results so hydration can advance and UI status remains accurate.
* fix(proxy): re-hook tray refresh events into proxy refresh queue
- Reattached listen("verge://refresh-proxy-config", …) at src/providers/app-data-provider.tsx:402 and registered it for cleanup.
- Added matching window fallback handler at src/providers/app-data-provider.tsx:430 so in-app dispatches share the same refresh path.
* fix(proxy-snapshot/proxy-groups): address review findings on snapshot placeholders
- src/utils/proxy-snapshot.ts:72-95 now derives snapshot group members solely from proxy-groups.proxies, so provider ids under `use` no longer generate placeholder proxy items.
- src/components/proxy/proxy-groups.tsx:665-677 lets the hydration overlay capture pointer events (and shows a wait cursor) so users can’t interact with snapshot-only placeholders before live data is ready.
* fix(profile-switch): preserve queued requests and avoid stale connection teardown
- Keep earlier queued switches intact by dropping the blanket “collapse” call: after removing duplicates for the same profile, new requests are simply appended, leaving other profiles pending (driver.rs:376). Resolves queue-loss scenario.
- Gate connection cleanup on real successes so cancelled/stale runs no longer tear down Mihomo connections; success handler now skips close_connections_after_switch when success == false (workflow.rs:419).
* fix(profile-switch, layout): improve profile validation and restore backend refresh
- Hardened profile validation using `tokio::fs` with a 5s timeout and offloading YAML parsing to `AsyncHandler::spawn_blocking`, preventing slow disks or malformed files from freezing the runtime (src-tauri/src/cmd/profile_switch/validation.rs:9, 71).
- Restored backend-triggered refresh handling by listening for `verge://refresh-clash-config` / `verge://refresh-verge-config` and invoking shared refresh services so SWR caches stay in sync with core events (src/pages/_layout/useLayoutEvents.ts:6, 45, 55).
* feat(profile-switch): handle cancellations for superseded requests
- Added a `cancelled` flag and constructor so superseded requests publish an explicit cancellation instead of a failure (src-tauri/src/cmd/profile_switch/state.rs:249, src-tauri/src/cmd/profile_switch/driver.rs:482)
- Updated the profile switch effect to log cancellations as info, retain the shared `mutate` call, and skip emitting error toasts while still refreshing follow-up work (src/pages/profiles.tsx:554, src/pages/profiles.tsx:581)
- Exposed the new flag on the TypeScript contract to keep downstream consumers type-safe (src/services/cmds.ts:20)
* fix(profiles): wrap logging payload for Tauri frontend_log
* fix(profile-switch): add rollback and error propagation for failed persistence
- Added rollback on apply failure so Mihomo restores to the previous profile
before exiting the success path early (state_machine.rs:474).
- Reworked persist_profiles_with_timeout to surface timeout/join/save errors,
convert them into CmdResult failures, and trigger rollback + error propagation
when persistence fails (state_machine.rs:703).
* fix(profile-switch): prevent mid-finalize reentrancy and lingering tasks
* fix(profile-switch): preserve pending queue and surface discarded switches
* fix(profile-switch): avoid draining Mihomo sockets on failed/cancelled switches
* fix(app-data-provider): restore backend-driven refresh and reattach fallbacks
* fix(profile-switch): queue concurrent updates and add bounded wait/backoff
* fix(proxy): trigger live refresh on app start for proxy snapshot
* refactor(profile-switch): split flow into layers and centralize async cleanup
- Introduced `SwitchDriver` to encapsulate queue and driver logic while keeping the public Tauri command API.
- Added workflow/cleanup helpers for notification dispatch and Mihomo connection draining, re-exported for API consistency.
- Replaced monolithic state machine with `core.rs`, `context.rs`, and `stages.rs`, plus a thin `mod.rs` re-export layer; stage methods are now individually testable.
- Removed legacy `workflow/state_machine.rs` and adjusted visibility on re-exported types/constants to ensure compilation.
