Add `APPLICATION_SHARED` storage scope for cross-app state sharing (#311317) * shared application storage * add tests * fix tests Co-authored-by: Copilot <copilot@github.com> * add logging and address feedback * Add application shared storage scope Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Add fallback migration for APPLICATION_SHARED storage VS Code: AbstractStorageService.get() falls back from APPLICATION_SHARED to APPLICATION scope transparently, enabling lazy per-key migration without a registry. Agents App: SharedSQLiteStorageDatabase reads the host (VS Code) app's application storage DB as a fallback during getItems(), merging missing keys so shared data is available even before VS Code runs with new scope code. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Move storage fallback into Storage class with auto-migration Move the APPLICATION → APPLICATION_SHARED fallback logic from AbstractStorageService into the base Storage class via the new fallbackStorage property on IStorage. When a key is not found, the fallback is checked and the value is automatically written through to persist the migration. This eliminates duplicated fallback code in get/getBoolean/ getNumber and ensures write-through happens for all access patterns. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Make fallbackStorage an implementation detail of Storage Remove fallbackStorage from IStorage interface. It is now a property on the Storage class only, set directly by callers that have access to the concrete type. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Pass fallback storage via ApplicationSharedStorageMain constructor Wire up the application storage as fallback during doCreate() instead of post-init. The ApplicationStorageMain is created first and passed to ApplicationSharedStorageMain's constructor. The fallback is set on the Storage instance when the shared database is created, so it's ready by the time reads happen. Removes setFallbackStorage() method and post-init wiring. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Remove fallbackDatabasePath - use fallbackStorage only The in-memory fallbackStorage (application storage) makes the DB-level fallback (reading VS Code's DB from disk) redundant. Both VS Code and Agents App now use the same mechanism: the Storage.fallbackStorage property that reads from application storage and auto-migrates on hit. Removes getHostUserDataPath, IProductService dependency, and INativeEnvironmentService from StorageMainService. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Add MigratingStorage with persisted migration tracking Introduce MigratingStorage that migrates keys from a fallback storage on first access. Migrated keys are tracked via a persisted marker key (__$__migratedStorageMarker) in the DB so deleted keys are never resurrected from the fallback. - VS Code windows: MigratingStorage falls back to own APPLICATION storage for transparent key migration - Sessions windows: MigratingStorage falls back to host (VS Code) application storage loaded via IPC - Main process: ApplicationSharedStorageMain uses HostApplicationStorageMain for embedded app fallback - sharedDataFolderName added to product configuration - Workspace trust migration simplified (handled by MigratingStorage automatically) Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * fix compilation * minimise changes * some fixes Co-authored-by: Copilot <copilot@github.com> * fixes * fix * delete migrated key * fix removing migrated key * update distro * feedback * Fix MigratingStorage: persist marker only on actual migration Add key to migratedKeys immediately before checking fallback to prevent redundant lookups. Only persist the MIGRATED_KEY marker when a value was actually found and migrated, avoiding unnecessary writes when the key doesn't exist in the fallback.

sessions: move session grouping from management service to providers (#307198) * Move session grouping from management service to providers Sessions providers now own chat-to-session grouping and return ISession[] directly. The management service becomes a thin pass-through that tracks the active session and active chat. Key changes: - ISessionsProvider returns ISession[] from getSessions() with capabilities - CopilotChatSessionsProvider owns SessionsGroupModel and chat grouping - IChat slimmed to resource, title, status, and reactive properties - ISession gains mainChat; IActiveSession adds activeChat (management layer) - Unified sendAndCreateChat replaces separate sendRequest/sendAndCreateChat - Provider capabilities (multipleChatsPerSession) gate multi-chat UI - ISessionWorkspace.repositories renamed to folders - ISessionRepository renamed to ISessionFolder Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * fix compilation --------- Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

sessions: workspace picker emits folder URI, session type picker spans providers (#317525) * sessions: workspace picker emits folder URI, session type picker spans providers Refactor the new-session workspace picker so it selects only a folder URI instead of a (providerId, workspace) pair. The session management service resolves the provider from the URI at session-creation time. The session type picker now queries the management service for all session types every registered provider can serve for the folder, grouped by provider with a separator between groups. Highlights: - ISessionsManagementService gains: - getSessionTypesForFolder(folderUri): returns one entry per provider x sessionType supported for the URI. - resolveWorkspaceForFolder(folderUri): finds the first provider that can resolve the URI. - createNewSession(folderUri, options?): iterates providers and picks the first matching one when no providerId is supplied. - WorkspacePicker: - Emits URI | undefined; selectedFolderUri / setSelectedWorkspace(uri). - Drops the up-front quick-pick that asked the user to choose between multiple local providers when browsing. - Recents storage stores URI only (with backward-compat reads of old {uri, providerId} entries); recents resolution prefers the stored providerId hint so a re-picked folder stays with the same provider. - SessionTypePicker: - Reads getSessionTypesForFolder; groups items by provider with a separator between groups and the provider label as a header. - Emits IPickedSessionType = { providerId, sessionTypeId } so the same sessionType id (e.g. 'copilot-cli') from different providers is disambiguated. - Recomputes types at open time as a safety net for late-registering providers. - SessionsManagementService._updateSessionTypes now fires onDidChangeSessionTypes unconditionally; the previous dedup check skipped the event when a new provider contributed an overlapping sessionType id, leaving the per-folder list stale. - LocalAgentHostSessionsProvider drops the `[Local]` suffix from workspace labels so its sessions for a folder share the workspace group with other providers' sessions for the same folder. - NewChatViewPane is rewired to the URI flow and uses the picker's selectedResolved.providerId as the createNewSession fallback when the session type picker has no explicit pick yet, preserving the user's historical provider association for recently-picked folders.

The new provider uses IChatService directly instead of the agent sessions model: - startNewLocalSession() for creating chat models - sendRequest() for sending messages - IGitService for git state resolution Changes: - New LocalChatSessionsProvider implementing ISessionsProvider - New localChatSessions.contribution.ts with setting registration and ForkConversationAction override - Removed LocalNewSession class from copilotChatSessionsProvider - Removed LOCAL_SESSION_ENABLED_SETTING from copilot provider - Updated copilotChatSessionsActions to import LocalSessionType from new provider - Updated sessions.common.main.ts entry point Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

sessions: clean up ISessionsProvider chat API (#317875) * sessions: clean up ISessionsProvider chat API Simplify the provider contract and remove provider access to the chat widget service so widget opening is owned exclusively by the management service. Provider API - Remove `sendAndCreateChat` and `addChat` from `ISessionsProvider`. - Add `createNewChat(sessionId)` returning the committed `IChat` so the management service can open the widget on the real backend resource before sending. - `sendRequest(sessionId, chatResource, options)` now handles both the first-send (new session) and subsequent-send paths; providers dispatch internally based on `_currentNewSession`. - For multi-chat sessions, `createNewChat` on an existing session gates on `_isMultiChatEnabled()` and creates a fresh chat in the group. Session model - `ISession.mainChat` changes from `IChat` to `IObservable<IChat>` so providers can swap the chat when an untitled new session commits to a real backend resource (e.g. Claude). - `ICopilotChatSession` owns its own `ISettableObservable<IChat>` `mainChat` field; the provider no longer maintains a parallel map. Management service - `sendNewChatRequest` (renamed from `sendAndCreateChat`) calls `createNewChat`, opens the widget on the returned chat resource, then calls `sendRequest`. - `openNewChatInSession` is now async and opens the widget after `createNewChat` returns. Copilot provider - Drops the `IChatWidgetService` injection; the provider never opens widgets directly. - Drops `userSelectedTools` from the local send path (no widget available there). Spec - `SESSIONS.md`: document that `ISessionsProvider` must not have optional methods and that every addition to `ISession` or `ISessionsProvider` must be consumed by the agents-window core workbench (outside `contrib/providers/`). - `COPILOT_CHAT_SESSIONS_PROVIDER.md`: update the send-flow section to describe the new `createNewChat` + `sendRequest` two-step contract.

agents: add smoke test for Agents Window with mocked LLM server (#317545) * agents: add smoke test for Agents Window with mocked LLM server Adds a smoke test that opens the Agents Window, creates a new session on a workspace folder, sends a 'hello world' prompt, and verifies the request reaches a local mock LLM server that returns a canned response. The test exercises two session types: Copilot CLI and Claude Code. A third Local-session test is included but marked `it.skip` for now. Key pieces: * `test/smoke/src/areas/agents/agents.test.ts` — new smoke suite. Starts `scripts/chat-simulation/common/mock-llm-server.js` on a random port, registers a per-test scenario with a distinct reply, and injects `VSCODE_COPILOT_CHAT_TOKEN` / `GITHUB_PAT` / `IS_SCENARIO_AUTOMATION` env vars so the Copilot extension's token manager picks up a fake token whose endpoints.api/proxy point at the mock server. * `test/automation/src/agents.ts` — new `Agents` workbench helper with `openCurrentFolderInAgentsWindow`, `switchToAgentsWindow`, `startNewSession`, `selectSessionType`, `submitNewSessionPrompt`, `waitForAssistantText`. * `test/automation/src/code.ts` + `electron.ts` — `LaunchOptions` now accepts an `extraEnv` map that is merged on top of `process.env` when spawning the Electron child, so tests can inject env-based mocks without going through a custom launcher. * `src/vs/sessions/browser/sessionsSetUpService.ts` — `shouldSkipSessionsWelcome` now returns `true` whenever `enableSmokeTestDriver` is set, so the welcome/auth dialog does not block smoke runs. * `scripts/chat-simulation/common/mock-llm-server.js` — adds two models to `EXTRA_MODELS` (`gpt-5.3-codex` for Copilot CLI default, `claude-sonnet-4.5` for Claude Code), and routes `/v1/messages` to a new `handleMessagesApi` that streams Anthropic-format SSE (`message_start` / `content_block_delta` / `message_stop`) which the Claude Code session type's messages-API parser expects. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Potential fix for pull request finding Co-authored-by: Copilot Autofix powered by AI <175728472+Copilot@users.noreply.github.com> * fix copilot cli test * skip claude test * sessions: fix new-session removal regression and rename smoke test 1. Revert the `_refreshSessionCache` filter change from d5747b31c42 back to `adapter instanceof AgentSessionAdapter`. The broadened `adapter !== this._currentNewSession` check raced with the unconditional `this._currentNewSession = undefined` in the `_sendFirstChat*` paths: a late callback from a previous session's commit would wipe the pointer and the next refresh would evict the new session's temp adapter, navigating the Agents Window back to the homepage mid-request. 2. Rename the Agents Window smoke test infrastructure for clarity: - `test/automation/src/agents.ts` -> `agentsWindow.ts` (class `Agents` -> `AgentsWindow`, `workbench.agents` -> `workbench.agentsWindow`) - `test/smoke/src/areas/agents/agents.test.ts` -> `areas/agentsWindow/agentsWindow.test.ts` Verified with 10 consecutive smoke-test loops: 8/10 fully green (Copilot CLI + Claude + Local), 2 intermittent UI timing flakes unrelated to the navigation regression. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * agents smoke: address PR #317545 review feedback - switchToAgentsWindow: replace fixed 2s sleep with waitForElement on the Agents workbench DOM (`.agent-sessions-workbench`) so the helper returns as soon as the new window is interactable. - resolveElectronConfiguration: apply `extraEnv` last, after the TESTRESOLVER_* assignments in the remote branch, so caller-provided env vars truly have final precedence. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * agents smoke: skip Agents Window tests for OSS quality The Copilot extension is not built in OSS CI (it's in excludedExtensions and its dist/extension.js is only produced by its own esbuild pipeline). Without it all three session-type providers fail to activate, causing every Agents Window test to time out. Skip the suite when quality is OSS, matching the pattern used by setupExtensionTests and setupLocalizationTests. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * copilotcli: add proxy endpoint to getAuthInfo for mock server routing Without `endpoints.proxy`, the SDK's model-fetch calls (`/models/session`, `/copilot_internal/v2/token`) fall back to the real GitHub API which rejects the fake HMAC with a 401. This caused intermittent smoke test failures (1 in 10) because the Copilot CLI language models never registered, making the chat-setup readiness gate depend on Claude's model registration timing. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * copilotcli: don't cache failed model fetches When `getAvailableModels` throws (e.g. transient network failure or HMAC validation error with a proxy), the empty result was permanently cached in `_availableModels`. Subsequent calls to `getModels()` would return the cached empty array without retrying, leaving the Copilot CLI language model provider with zero models for the rest of the session. Clear `_availableModels` on error so the next call retries the fetch. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * agents smoke: reset workspace before opening Agents Window Earlier smoke test suites (e.g. Tasks) modify .vscode/tasks.json and leave uncommitted changes. A dirty workspace prevents worktree creation and triggers the uncommitted-changes confirmation flow which aborts the Copilot CLI session on builds. Reset via `git checkout . --quiet` in the before hook, matching the pattern used by notebook and search smoke tests.

sessions: add multi-chat support to Copilot provider (#preview) (#307258) * sessions: add multi-chat support to Copilot provider (#preview) Add support for multiple chats within a single session in the Copilot Chat sessions provider, gated behind the preview setting `sessions.github.copilot.multiChatSessions`. Key changes: - Integrate SessionsGroupModel into CopilotChatSessionsProvider for chat-to-session grouping with storage persistence - Add _sendSubsequentChat() for creating new chats in existing sessions with workspace isolation mode - _chatToSession() builds multi-chat observable from group model with aggregated status, updatedAt, isRead, lastTurnEnd across all chats - Session title and properties always come from the primary (first) chat - getSessions() deduplicates by group ID when multi-chat is enabled - deleteSession() removes all chats in the group - deleteChat() removes individual chats; delegates to deleteSession when only one chat remains - _refreshSessionCacheMultiChat() handles removed chats that belong to groups with siblings as changed events on the parent session - Management service tracks active chat via autorun on chats observable - All multi-chat code paths fall back to single-chat behavior when the setting is disabled - Comprehensive unit tests for the provider * address feedback
