The :class:`LSPService` is the bridge between the synchronous file_operations layer and the async :class:`agent.lsp.client.LSPClient`. Design choices: - A **single asyncio event loop** runs in a background thread. All client work happens on that loop. Synchronous callers from ``tools/file_operations.py`` use :meth:`get_diagnostics_sync` to open + wait + drain in one blocking call. - One client per ``(server_id, workspace_root)`` key. Lazy spawn: the first request for a key spawns the client; subsequent requests re-use it. - A **broken-set** records ``(server_id, workspace_root)`` pairs that failed to spawn or initialize. These are never retried for the life of the service. Mirrors OpenCode's design. - A **delta baseline** map keeps "diagnostics-as-of-the-last-snapshot" per file. ``snapshot_baseline()`` is called BEFORE a write; the next ``get_diagnostics_sync()`` returns only diagnostics that weren't in the baseline. This is the lift from Claude Code's ``beforeFileEdited`` / ``getNewDiagnostics`` pattern, except wired to the local LSP layer instead of MCP IDE RPC. The service is **off by default** — call :meth:`is_active` to check whether it's actually doing anything. When LSP is disabled in config, when no git workspace can be detected, when all configured servers are missing binaries and auto-install is off, ``is_active`` returns False and the file_operations layer falls through to the in-process syntax check. ) annotationsN)AnyCallableDictListOptionalTuple)eventlog)DIAGNOSTICS_DOCUMENT_WAIT LSPClient) ServerContextfind_server_for_filelanguage_id_for) clear_cacheresolve_workspace_for_filezagent.lsp.manageriXc@eZdZdZddZddZddZdddd Zdd ZdS)_BackgroundLoopuA daemon thread that owns one asyncio event loop.

If ``delta`` is True (default), the result is filtered against any baseline previously captured via :meth:`snapshot_baseline`. Diagnostics present in the baseline are removed so the caller only sees errors introduced by the current edit. When ``line_shift`` is provided, baseline diagnostics are remapped through it before the set-difference. This handles the case where the edit deleted or inserted lines, causing pre-existing diagnostics below the edit point to surface at different line numbers in the post-edit snapshot — without the shift, they'd all look "introduced by this edit". Pass a callable built by :func:`agent.lsp.range_shift.build_line_shift` (pre_text, post_text). Omit when pre/post content isn't available; the unshifted comparison still catches diagnostics that didn't move. Returns an empty list when LSP is disabled, when no workspace can be detected, when no server matches, or when the server can't be spawned.
