From 97773863ef67bdf293c1d832864ca22213e63f4b Mon Sep 17 00:00:00 2001 From: JeffreyChen Date: Sun, 26 Apr 2026 17:20:58 +0800 Subject: [PATCH 01/21] Add OCR region dump and regex search APIs Existing OCR only supported substring/exact target search. read_text_in_region returns every recognised text record so callers can scrape full panels, and find_text_regex enables pattern-based matching (order numbers, error codes). Both are wired into the executor as AC_read_text_in_region and AC_find_text_regex so JSON action scripts can use them headlessly. --- je_auto_control/__init__.py | 8 +- .../utils/executor/action_executor.py | 39 ++++++++++ je_auto_control/utils/ocr/ocr_engine.py | 30 +++++++- test/unit_test/headless/test_ocr_engine.py | 75 ++++++++++++++++++- 4 files changed, 147 insertions(+), 5 deletions(-) diff --git a/je_auto_control/__init__.py b/je_auto_control/__init__.py index 9f45a02a..d6d513b2 100644 --- a/je_auto_control/__init__.py +++ b/je_auto_control/__init__.py @@ -59,8 +59,9 @@ ) # OCR (headless) from je_auto_control.utils.ocr.ocr_engine import ( - TextMatch, click_text, find_text_matches, locate_text_center, - set_tesseract_cmd, wait_for_text, + TextMatch, click_text, find_text_matches, find_text_regex, + locate_text_center, read_text_in_region, set_tesseract_cmd, + wait_for_text, ) # MCP server (headless stdio bridge for Claude / other MCP clients) from je_auto_control.utils.mcp_server import ( @@ -203,7 +204,8 @@ def start_autocontrol_gui(*args, **kwargs): "add_command_to_executor", "test_record_instance", "pil_screenshot", # OCR "TextMatch", "find_text_matches", "locate_text_center", "wait_for_text", - "click_text", "set_tesseract_cmd", + "click_text", "set_tesseract_cmd", "read_text_in_region", + "find_text_regex", # Recording editor "trim_actions", "insert_action", "remove_action", "filter_actions", "adjust_delays", "scale_coordinates", diff --git a/je_auto_control/utils/executor/action_executor.py b/je_auto_control/utils/executor/action_executor.py index de0d93a1..5307bb52 100644 --- a/je_auto_control/utils/executor/action_executor.py +++ b/je_auto_control/utils/executor/action_executor.py @@ -25,7 +25,9 @@ from je_auto_control.utils.executor.mouse_aliases import MOUSE_BUTTON_COMMANDS from je_auto_control.utils.ocr.ocr_engine import ( click_text as ocr_click_text, + find_text_regex as ocr_find_text_regex, locate_text_center as ocr_locate_text_center, + read_text_in_region as ocr_read_text_in_region, wait_for_text as ocr_wait_for_text, ) from je_auto_control.utils.run_history.history_store import default_history_store @@ -92,6 +94,41 @@ def _vlm_locate_as_list(description: str, return None if coords is None else [coords[0], coords[1]] +def _ocr_read_region_as_dicts(region: Optional[List[int]] = None, + lang: str = "eng", + min_confidence: float = 60.0) -> List[dict]: + """Executor adapter: dump OCR hits in a region as JSON-friendly dicts.""" + return [ + { + "text": match.text, "x": match.x, "y": match.y, + "width": match.width, "height": match.height, + "confidence": match.confidence, + } + for match in ocr_read_text_in_region( + region=region, lang=lang, min_confidence=float(min_confidence), + ) + ] + + +def _ocr_find_regex_as_dicts(pattern: str, + lang: str = "eng", + region: Optional[List[int]] = None, + min_confidence: float = 60.0, + flags: int = 0) -> List[dict]: + """Executor adapter: regex OCR search returning JSON-friendly dicts.""" + return [ + { + "text": match.text, "x": match.x, "y": match.y, + "width": match.width, "height": match.height, + "confidence": match.confidence, + } + for match in ocr_find_text_regex( + pattern, lang=lang, region=region, + min_confidence=float(min_confidence), flags=int(flags), + ) + ] + + def _history_list_as_dicts(limit: int = 100, source_type: Optional[str] = None) -> List[dict]: """Executor adapter: list run history as plain dicts (JSON-friendly).""" @@ -186,6 +223,8 @@ def __init__(self): "AC_locate_text": ocr_locate_text_center, "AC_wait_text": ocr_wait_for_text, "AC_click_text": ocr_click_text, + "AC_read_text_in_region": _ocr_read_region_as_dicts, + "AC_find_text_regex": _ocr_find_regex_as_dicts, # Window management "AC_list_windows": list_windows, diff --git a/je_auto_control/utils/ocr/ocr_engine.py b/je_auto_control/utils/ocr/ocr_engine.py index e3f99926..70bd85ce 100644 --- a/je_auto_control/utils/ocr/ocr_engine.py +++ b/je_auto_control/utils/ocr/ocr_engine.py @@ -4,9 +4,10 @@ binary is loaded lazily; if it is missing, a clear ``RuntimeError`` is raised rather than ``ImportError`` so callers can degrade gracefully.

VariableScope is a runtime mapping the executor exposes to flow-control commands so AC_set_var / AC_inc_var / AC_get_var, AC_if_var (with eq/ne/lt/le/gt/ge/contains/startswith/endswith), and AC_for_each can read and write the same bag the runtime interpolator consults. The executor now resolves ${var} per command call (not pre-flattened), so nested body/then/else lists keep their placeholders and re-bind each time they execute — letting AC_for_each iterate over a list while the body sees the current item. --- je_auto_control/__init__.py | 2 + .../utils/executor/action_executor.py | 48 +++++++- .../utils/executor/action_schema.py | 2 +

17:39:22 +0800 Subject: [PATCH 03/21] Add LLM action planner with Anthropic backend plan_actions() turns a natural-language description into a validated AC_* action list by asking an LLM (Anthropic Claude by default) to emit JSON constrained to the executor's known commands. Output is parsed leniently (strips code fences, extracts the first JSON array from prose) and then validated by the same schema the executor uses, so callers can pipe the result straight into execute_action. Backend selection mirrors utils/vision: an LLMBackend protocol with an Anthropic implementation and a null fallback that fails fast when no key or SDK is present. AC_llm_plan / AC_llm_run executor commands expose the flow to JSON action files, the socket server, and the MCP bridge. --- je_auto_control/__init__.py | 8 + .../utils/executor/action_executor.py | 36 +++++ je_auto_control/utils/llm/__init__.py | 20 +++ .../utils/llm/backends/__init__.py | 67 ++++++++ .../utils/llm/backends/anthropic_backend.py | 72 +++++++++ je_auto_control/utils/llm/backends/base.py | 24 +++ .../utils/llm/backends/null_backend.py | 23 +++ je_auto_control/utils/llm/planner.py | 145 ++++++++++++++++++ test/unit_test/headless/test_llm_planner.py | 144 +++++++++++++++++ 9 files changed, 539 insertions(+) create mode 100644 je_auto_control/utils/llm/__init__.py create mode 100644 je_auto_control/utils/llm/backends/__init__.py create mode 100644 je_auto_control/utils/llm/backends/anthropic_backend.py create mode 100644 je_auto_control/utils/llm/backends/base.py create mode 100644 je_auto_control/utils/llm/backends/null_backend.py create mode 100644 je_auto_control/utils/llm/planner.py create mode 100644 test/unit_test/headless/test_llm_planner.py diff --git a/je_auto_control/__init__.py b/je_auto_control/__init__.py index 079fbabf..9b1aa197 100644 --- a/je_auto_control/__init__.py +++ b/je_auto_control/__init__.py @@ -63,6 +63,11 @@ locate_text_center, read_text_in_region, set_tesseract_cmd, wait_for_text, ) +# LLM action planner (headless) +from je_auto_control.utils.llm import ( + LLMBackend, LLMNotAvailableError, LLMPlanError, + plan_actions, run_from_description, +) #

CLAUDE.md requires every feature to ship with both headless and GUI surfaces, so this adds thin Qt wrappers: - OCRReaderTab: region picker + dump-region + regex-search, sharing the existing region selector overlay - VariablesTab: live view of executor.variables with single-set, JSON seed, and clear-all controls; reflects what AC_set_var / AC_for_each mutate at runtime - LLMPlannerTab: description box, plan preview, and run-plan button; planning runs on a QThread so the UI stays responsive during the LLM call Translations added for English, Traditional Chinese, Simplified Chinese, and Japanese. --- .../gui/language_wrapper/english.py | 61 ++++++ .../gui/language_wrapper/japanese.py | 61 ++++++ .../language_wrapper/simplified_chinese.py | 61 ++++++ .../language_wrapper/traditional_chinese.py | 61 ++++++ je_auto_control/gui/llm_planner_tab.py | 195 ++++++++++++++++++ je_auto_control/gui/main_widget.py | 6 + je_auto_control/gui/ocr_tab.py | 172 +++++++++++++++ je_auto_control/gui/variables_tab.py | 169 +++++++++++++++ 8 files changed, 786 insertions(+) create mode 100644 je_auto_control/gui/llm_planner_tab.py create mode 100644 je_auto_control/gui/ocr_tab.py create mode 100644 je_auto_control/gui/variables_tab.py diff --git a/je_auto_control/gui/language_wrapper/english.py b/je_auto_control/gui/language_wrapper/english.py index 40efca04..ceb374ad 100644 --- a/je_auto_control/gui/language_wrapper/english.py +++ b/je_auto_control/gui/language_wrapper/english.py @@ -27,6 +27,9 @@ "tab_run_history": "Run History", "tab_accessibility": "Accessibility", "tab_vlm": "AI Locator", + "tab_ocr_reader": "OCR Reader", + "tab_variables": "Variables", + "tab_llm_planner": "LLM Planner", #

05/21] Add remote_desktop host and viewer (headless) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit A new utils/remote_desktop module lets one machine stream its screen and receive input from another. The wire format is a length-prefixed framing on raw TCP (no extra deps), starting with an HMAC-SHA256 challenge/response handshake; viewers that fail auth are dropped before they can see a frame. Host: capture loop encodes JPEG frames at the configured fps/quality and broadcasts them to authenticated viewers via a shared latest-frame slot + Condition, so a slow viewer drops frames instead of blocking the rest. Viewer input messages are JSON, validated against an allowlist, and applied through the existing wrapper helpers (lazy-imported so the viewer side stays platform-agnostic). Defaults bind to 127.0.0.1 — exposing this to untrusted networks should be paired with an SSH tunnel or TLS front-end. Tests cover the protocol, auth, the dispatch allowlist, and a full localhost host<->viewer round-trip including auth failure and graceful shutdown. --- .../utils/remote_desktop/__init__.py | 27 ++ je_auto_control/utils/remote_desktop/auth.py | 28 ++ je_auto_control/utils/remote_desktop/host.py | 358 ++++++++++++++++++ .../utils/remote_desktop/input_dispatch.py | 117 ++++++ .../utils/remote_desktop/protocol.py | 87 +++++ .../utils/remote_desktop/viewer.py | 187 +++++++++ .../test_remote_desktop_input_dispatch.py | 88 +++++ .../headless/test_remote_desktop_io.py | 163 ++++++++ .../headless/test_remote_desktop_protocol.py | 79 ++++ 9 files changed, 1134 insertions(+) create mode 100644 je_auto_control/utils/remote_desktop/__init__.py create mode 100644 je_auto_control/utils/remote_desktop/auth.py create mode 100644 je_auto_control/utils/remote_desktop/host.py create mode 100644 je_auto_control/utils/remote_desktop/input_dispatch.py create mode 100644 je_auto_control/utils/remote_desktop/protocol.py create mode 100644 je_auto_control/utils/remote_desktop/viewer.py create mode 100644 test/unit_test/headless/test_remote_desktop_input_dispatch.py create mode 100644 test/unit_test/headless/test_remote_desktop_io.py create mode 100644 test/unit_test/headless/test_remote_desktop_protocol.py diff --git a/je_auto_control/utils/remote_desktop/__init__.py b/je_auto_control/utils/remote_desktop/__init__.py new file mode 100644 index 00000000..1ccf29c2 --- /dev/null +++ b/je_auto_control/utils/remote_desktop/__init__.py @@ -0,0 +1,27 @@ +"""Remote-desktop host/viewer for screen streaming and remote input. + +The protocol is a minimal length-prefixed framing on raw TCP (no extra +deps).

2001 From: JeffreyChen Date: Sun, 26 Apr 2026 18:23:32 +0800 Subject: [PATCH 06/21] Wire AC_remote_* commands and facade re-exports for remote_desktop A small registry singleton holds at most one host and one viewer so JSON action scripts and the GUI can talk to the running pair without juggling handles. The new AC_start_remote_host / AC_stop_remote_host / AC_remote_host_status, AC_remote_connect / AC_remote_disconnect / AC_remote_viewer_status / AC_remote_send_input commands are thin adapters over the registry, so the executor stays unaware of the host and viewer classes' lifecycle details. Tests cover the AC_* command surface and an end-to-end round-trip (executor-driven host start, viewer connect, send_input, disconnect, stop) with stub frame provider and dispatcher so no real screen capture or OS input is needed. --- je_auto_control/__init__.py | 14 +++ .../utils/executor/action_executor.py | 57 +++++++++ .../utils/remote_desktop/__init__.py | 3 +- .../utils/remote_desktop/registry.py | 94 ++++++++++++++ .../headless/test_remote_desktop_executor.py | 117 ++++++++++++++++++ 5 files changed, 284 insertions(+), 1 deletion(-) create mode 100644 je_auto_control/utils/remote_desktop/registry.py create mode 100644 test/unit_test/headless/test_remote_desktop_executor.py diff --git a/je_auto_control/__init__.py b/je_auto_control/__init__.py index 9b1aa197..7d0747e2 100644 --- a/je_auto_control/__init__.py +++ b/je_auto_control/__init__.py @@ -68,6 +68,16 @@ LLMBackend, LLMNotAvailableError, LLMPlanError, plan_actions, run_from_description, ) +# Remote desktop (headless) +from je_auto_control.utils.remote_desktop import ( + AuthenticationError as RemoteDesktopAuthError, + InputDispatchError as RemoteDesktopInputError, + ProtocolError as RemoteDesktopProtocolError, + RemoteDesktopHost, RemoteDesktopViewer, +) +from je_auto_control.utils.remote_desktop.registry import ( + registry as remote_desktop_registry, +) #

Mouse / wheel / key events on the display are remapped from widget coordinates back to the remote screen's pixel space using the latest frame's dimensions, then forwarded as INPUT messages.

Sun, 26 Apr 2026 18:37:49 +0800 Subject: [PATCH 08/21] Show frames on both ends of Remote Desktop and harden viewer connect MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The Host sub-tab previously had only text status — the user being remoted could not tell what the connected viewers actually saw. Adds a preview pane below the controls driven by a 4 fps QTimer that polls the host's new public latest_frame() helper. The pane is disabled so a host watching themselves cannot self-trigger fake input through the local widget. Viewer connect was racy: callbacks were patched on the viewer instance *after* connect() returned, so frames received in the gap between the receiver thread starting and the GUI patching _on_frame were dropped silently. registry.connect_viewer now accepts on_frame / on_error and threads them through RemoteDesktopViewer.__init__, so the receiver thread is born with the right callbacks. Adds three Qt integration tests that run against an offscreen QApplication and prove end-to-end: viewer panel decodes and shows incoming JPEG frames, host preview mirrors what is streamed, and viewer mouse events round-trip back to the host's input dispatcher. --- .../gui/language_wrapper/english.py | 1 + .../gui/language_wrapper/japanese.py | 1 + .../language_wrapper/simplified_chinese.py | 1 + .../language_wrapper/traditional_chinese.py | 1 + je_auto_control/gui/remote_desktop_tab.py | 33 +++- je_auto_control/utils/remote_desktop/host.py | 9 ++ .../utils/remote_desktop/registry.py | 22 ++- .../headless/test_remote_desktop_gui.py | 149 ++++++++++++++++++ 8 files changed, 207 insertions(+), 10 deletions(-) create mode 100644 test/unit_test/headless/test_remote_desktop_gui.py diff --git a/je_auto_control/gui/language_wrapper/english.py b/je_auto_control/gui/language_wrapper/english.py index 8a97ded2..85989e78 100644 --- a/je_auto_control/gui/language_wrapper/english.py +++ b/je_auto_control/gui/language_wrapper/english.py @@ -400,6 +400,7 @@ "rd_host_stop": "Stop host", "rd_host_status_running": "Running on port {port} — {n} viewer(s)", "rd_host_status_stopped": "Host is stopped", + "rd_host_preview_label": "Preview (what viewers see):", "rd_viewer_connect": "Connect", "rd_viewer_disconnect": "Disconnect", "rd_viewer_required_fields": ( diff --git a/je_auto_control/gui/language_wrapper/japanese.py b/je_auto_control/gui/language_wrapper/japanese.py index e81fea32..35158e91 100644 --- a/je_auto_control/gui/language_wrapper/japanese.py +++ b/je_auto_control/gui/language_wrapper/japanese.py @@ -400,6 +400,7 @@ "rd_host_stop": "ホスト停止", "rd_host_status_running": "稼働中 ポート {port} — ビューア {n} 名", "rd_host_status_stopped": "ホストは停止中", + "rd_host_preview_label": "プレビュー（ビューアの表示）:", "rd_viewer_connect": "接続", "rd_viewer_disconnect": "切断", "rd_viewer_required_fields": "アドレス・ポート・トークンはすべて必須です。", diff --git a/je_auto_control/gui/language_wrapper/simplified_chinese.py b/je_auto_control/gui/language_wrapper/simplified_chinese.py index 593734ec..98a267c5 100644 --- a/je_auto_control/gui/language_wrapper/simplified_chinese.py +++ b/je_auto_control/gui/language_wrapper/simplified_chinese.py @@ -394,6 +394,7 @@ "rd_host_stop": "停止 Host", "rd_host_status_running": "运行中 端口 {port} — {n} 个 viewer", "rd_host_status_stopped": "Host 已停止", + "rd_host_preview_label": "预览（viewer 看到的画面）：", "rd_viewer_connect": "连接", "rd_viewer_disconnect": "断开", "rd_viewer_required_fields": "地址、端口、token 都必须填写。", diff --git a/je_auto_control/gui/language_wrapper/traditional_chinese.py b/je_auto_control/gui/language_wrapper/traditional_chinese.py index f355a71c..1bc787b2 100644 --- a/je_auto_control/gui/language_wrapper/traditional_chinese.py +++ b/je_auto_control/gui/language_wrapper/traditional_chinese.py @@ -395,6 +395,7 @@ "rd_host_stop": "停止 Host", "rd_host_status_running": "運行中 port {port} — {n} 個 viewer", "rd_host_status_stopped": "Host 已停止", + "rd_host_preview_label": "預覽（viewer 看到的畫面）：", "rd_viewer_connect": "連線", "rd_viewer_disconnect": "中斷連線", "rd_viewer_required_fields": "位址、port、token 都必須填寫。", diff --git a/je_auto_control/gui/remote_desktop_tab.py b/je_auto_control/gui/remote_desktop_tab.py index c3e14198..e0b90224 100644 --- a/je_auto_control/gui/remote_desktop_tab.py +++ b/je_auto_control/gui/remote_desktop_tab.py @@ -207,7 +207,9 @@ def keyReleaseEvent(self, event: QKeyEvent) -> None: # noqa: N802 class _HostPanel(TranslatableMixin, QWidget): -

The ID is announced inside AUTH_OK as JSON so only authenticated viewers see it. Viewers that pass expected_host_id raise AuthenticationError when the announced ID does not match, defending against TCP-level impersonation by a different process listening on the same address. The ID is *not* a substitute for the auth token — token-based HMAC gates the actual session; the ID is meant to be shared (token + ID together identify a host). --- .../utils/remote_desktop/__init__.py | 6 + je_auto_control/utils/remote_desktop/host.py | 16 +- .../utils/remote_desktop/host_id.py | 81 ++++++++++ .../utils/remote_desktop/registry.py | 22 ++- .../utils/remote_desktop/viewer.py | 34 ++++ .../headless/test_remote_desktop_host_id.py | 153 ++++++++++++++++++ 6 files changed, 306 insertions(+), 6 deletions(-) create mode 100644 je_auto_control/utils/remote_desktop/host_id.py create mode 100644 test/unit_test/headless/test_remote_desktop_host_id.py diff --git a/je_auto_control/utils/remote_desktop/__init__.py b/je_auto_control/utils/remote_desktop/__init__.py index 2eb55497..9c569d6a 100644 --- a/je_auto_control/utils/remote_desktop/__init__.py +++ b/je_auto_control/utils/remote_desktop/__init__.py @@ -10,6 +10,10 @@ front-end.

17 00:00:00 2001 From: JeffreyChen Date: Sun, 26 Apr 2026 19:10:57 +0800 Subject: [PATCH 11/21] Add TLS transport for Remote Desktop host and viewer RemoteDesktopHost and RemoteDesktopViewer now accept an ssl.SSLContext; when provided, the host wraps each accepted connection server-side and the viewer wraps the connect socket client-side. Failed handshakes on the host are logged and the raw socket is closed before the client handler is registered, so a TLS-only host can be hit by plain TCP viewers without leaking entries into the connected_clients counter. Tests use a self-signed loopback certificate generated with cryptography to cover: full TLS round-trip with both a trusting and an insecure client context, plain viewer rejected against a TLS host, TLS-only viewer rejected against a plain host, and confirmation that the wrapped socket is an SSLSocket after connect. --- je_auto_control/utils/remote_desktop/host.py | 31 ++- .../utils/remote_desktop/registry.py | 12 +- .../utils/remote_desktop/viewer.py | 29 ++- .../headless/test_remote_desktop_tls.py | 188 ++++++++++++++++++ 4 files changed, 252 insertions(+), 8 deletions(-) create mode 100644 test/unit_test/headless/test_remote_desktop_tls.py diff --git a/je_auto_control/utils/remote_desktop/host.py b/je_auto_control/utils/remote_desktop/host.py index b0877fbf..2d1eef48 100644 --- a/je_auto_control/utils/remote_desktop/host.py +++ b/je_auto_control/utils/remote_desktop/host.py @@ -1,6 +1,7 @@ """TCP host that streams JPEG frames and applies viewer input.""" import json import socket +import ssl import threading import time from io import BytesIO @@ -214,6 +215,7 @@ def __init__(self, token: str, frame_provider: Optional[FrameProvider] = None, input_dispatcher: Optional[InputDispatcher] = None, host_id: Optional[str] = None, + ssl_context: Optional[ssl.SSLContext] = None, ) -> None: if not isinstance(token, str) or not token: raise ValueError("token must be a non-empty string") @@ -224,6 +226,7 @@ def __init__(self, token: str, self._host_id = (validate_host_id(host_id) if host_id else load_or_create_host_id()) self._token = token + self._ssl_context = ssl_context self._bind = bind self._requested_port = int(port) self._period = 1.0 / float(fps) @@ -332,7 +335,10 @@ def _accept_loop(self) -> None: continue except OSError: return - handler = _ClientHandler(self, client_sock, address) + wrapped = self._maybe_wrap_tls(client_sock, address) + if wrapped is None: + continue + handler = _ClientHandler(self, wrapped, address) with self._clients_lock: if len(self._clients) >= self._max_clients: autocontrol_logger.info( @@ -345,6 +351,29 @@ def _accept_loop(self) -> None: handler.start() self._reap_dead_clients() + def _maybe_wrap_tls(self, client_sock: socket.socket, + address) -> Optional[socket.socket]: + """Return a TLS-wrapped socket when an ssl_context is configured.""" + if self._ssl_context is None: + return client_sock + try: + client_sock.settimeout(_AUTH_TIMEOUT_S) + wrapped = self._ssl_context.wrap_socket( + client_sock, server_side=True, + ) + wrapped.settimeout(None) + return wrapped + except (ssl.SSLError, OSError) as error: + autocontrol_logger.info( + "remote_desktop TLS handshake from %s failed: %r", + address, error, + ) + try: + client_sock.close() + except OSError: + pass + return None + def _capture_loop(self) -> None: next_tick = time.monotonic() while not self._shutdown.is_set(): diff --git a/je_auto_control/utils/remote_desktop/registry.py b/je_auto_control/utils/remote_desktop/registry.py index 33b23544..e88e48e8 100644 --- a/je_auto_control/utils/remote_desktop/registry.py +++ b/je_auto_control/utils/remote_desktop/registry.py @@ -5,6 +5,7 @@ references here keeps :mod:`action_executor` thin and avoids circular imports between the executor and the host/viewer classes.

Each WS frame carries one full encoded typed message (magic + type + length + payload), so decode_frame_header / encode_frame are reused unchanged and only the wire layer changes. ws_protocol.py is a small RFC 6455 implementation (no extra deps): server / client handshake helpers, single-frame BINARY send, recv that transparently handles PING / PONG / CLOSE control frames, and explicit rejection of fragmented data frames so messages always fit in one ~16 MiB frame. Clients mask outgoing payloads as required; servers do not. WebSocketDesktopHost and WebSocketDesktopViewer are thin subclasses that override the channel-creation hook to perform the upgrade handshake before falling back to the shared auth + receive loop. The existing ssl_context plumbing stays in place — passing a context to WebSocketDesktopHost/Viewer transparently upgrades the connection to wss://, so no separate TLS-WS class is needed. Tests cover ws_protocol round trips (handshake, masked + unmasked binary frames, extended payload length, bad-request rejection) and end-to-end host<->viewer scenarios (auth, frame stream, input dispatch, host_id announce, mixed-transport rejection in both directions, path validation). --- .../utils/remote_desktop/__init__.py | 5 + je_auto_control/utils/remote_desktop/host.py | 64 +++--

2026 21:32:22 +0800 Subject: [PATCH 13/21] Add audio streaming (host -> viewer PCM) for Remote Desktop MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit A new AUDIO message type carries 16-bit signed PCM blocks (16 kHz mono, 50 ms per block by default) alongside JPEG frames on the same channel. The 'sounddevice' dependency stays optional: audio.py imports it lazily so machines without PortAudio can still import the package, and a backend failure during host startup is logged + audio is reported disabled rather than tearing the host down. Host: enable_audio + audio_device / sample_rate / channels / block configure capture; the host's broadcast loop pushes each block into a bounded per-client deque (max ~2.5 s buffered), and a dedicated audio sender thread per client drains the queue. The bounded queue means a slow viewer drops old chunks instead of blocking the audio capture thread feeding everyone else. Viewer: a new on_audio callback fires on each AUDIO message; combined with AudioPlayer (also a thin sounddevice wrapper) callers get playback in two lines. The viewer never opens an audio device on its own — playback is opt-in. Tests fake sounddevice via monkeypatch and cover both unit-level behaviour (callback bytes, lazy backend, lifecycle, validation) and end-to-end host->viewer streaming, queue back-pressure, and graceful degradation when the backend cannot start. --- .../utils/remote_desktop/__init__.py | 6 + je_auto_control/utils/remote_desktop/audio.py | 193 +++++++++++++ je_auto_control/utils/remote_desktop/host.py | 119 +++++++- .../utils/remote_desktop/protocol.py | 1 + .../utils/remote_desktop/viewer.py | 12 + .../headless/test_remote_desktop_audio.py | 255 ++++++++++++++++++ 6 files changed, 585 insertions(+), 1 deletion(-) create mode 100644 je_auto_control/utils/remote_desktop/audio.py create mode 100644 test/unit_test/headless/test_remote_desktop_audio.py diff --git a/je_auto_control/utils/remote_desktop/__init__.py b/je_auto_control/utils/remote_desktop/__init__.py index 8aa9242c..6025eb31 100644 --- a/je_auto_control/utils/remote_desktop/__init__.py +++ b/je_auto_control/utils/remote_desktop/__init__.py @@ -9,6 +9,10 @@ it to untrusted networks should be paired with an SSH tunnel or TLS front-end.

Windows uses CF_DIB via ctypes (Pillow rasterises PNG -> BMP -> DIB); Linux shells out to 'xclip -t image/png'; macOS get works via Pillow ImageGrab and set raises a clear NotImplementedError pending a PyObjC backend. Host: broadcast_clipboard_text / broadcast_clipboard_image push to every authenticated viewer; incoming CLIPBOARD messages from a viewer are decoded and applied to the host's local clipboard via the helpers above. Viewer: send_clipboard_text / send_clipboard_image push to the host; incoming CLIPBOARD messages fire an on_clipboard(kind, data) callback so the GUI / library user controls when (and whether) to set the local clipboard. Sync is explicit per-call — no auto-polling that could create paste loops between the two sides. Tests cover the JSON serialisation contract (text + image, malformed input, unknown kinds, missing fields) and end-to-end host<->viewer flow with a recording host that captures apply calls instead of touching the OS clipboard. --- je_auto_control/utils/clipboard/clipboard.py | 158 ++++++++++++++++- .../utils/remote_desktop/__init__.py | 4 + .../utils/remote_desktop/clipboard_sync.py | 72 ++++++++ je_auto_control/utils/remote_desktop/host.py | 64 +++++++ .../utils/remote_desktop/protocol.py | 1 + .../utils/remote_desktop/viewer.py | 37 ++++ .../headless/test_remote_desktop_clipboard.py | 162 ++++++++++++++++++ 7 files changed, 494 insertions(+), 4 deletions(-) create mode 100644 je_auto_control/utils/remote_desktop/clipboard_sync.py create mode 100644 test/unit_test/headless/test_remote_desktop_clipboard.py diff --git a/je_auto_control/utils/clipboard/clipboard.py b/je_auto_control/utils/clipboard/clipboard.py index 761f3cb6..8d87bd8b 100644 --- a/je_auto_control/utils/clipboard/clipboard.py +++ b/je_auto_control/utils/clipboard/clipboard.py @@ -1,8 +1,11 @@ -"""Headless cross-platform text clipboard. +"""Headless cross-platform text + image clipboard. -Windows uses Win32 clipboard API via ctypes. -macOS shells out to pbcopy / pbpaste. -Linux shells out to xclip or xsel (whichever is available). +Windows uses Win32 clipboard API via ctypes (CF_UNICODETEXT for text, +CF_DIB for image). +macOS shells out to pbcopy / pbpaste for text; image support requires +PyObjC and is best effort. +Linux shells out to xclip / xsel for text and ``xclip -t image/png`` for +images.

f6b50befebb53b2b0f971f9ce357c01bb982c4cf Mon Sep 17 00:00:00 2001 From: JeffreyChen Date: Sun, 26 Apr 2026 21:39:53 +0800 Subject: [PATCH 15/21] Add bidirectional chunked file transfer for Remote Desktop MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Three new message types form one transfer: FILE_BEGIN carries JSON metadata (transfer_id, dest_path, size); FILE_CHUNK is a 36-byte ASCII transfer id followed by raw bytes; FILE_END carries a JSON status / error string. Sender path (utils/remote_desktop/file_transfer.send_file) opens the file synchronously, picks a UUID, streams 256 KiB chunks, and fires an on_progress(transfer_id, bytes_done, total) callback per chunk. The caller wraps in a thread for non-blocking uploads. Receiver (FileReceiver) demultiplexes by transfer_id so multiple in-flight files on one channel work, expanduser's ~ in dest_path, and creates parent directories. There is no aggregate size limit and no destination-path restriction — token holders are trusted users. Host: set_file_receiver attaches a custom receiver (with progress / complete callbacks); send_file_to_viewers streams a local file to every authenticated viewer.

charset=UTF-8 Content-Transfer-Encoding: 8bit Host panel: - Prominent Host ID display with a 'Copy' button so users can read it out (formatted as '123 456 789') and paste it into the viewer. - Transport dropdown (TCP / WebSocket) routes Start through either RemoteDesktopHost or WebSocketDesktopHost. - TLS cert / key fields with file pickers; both required to opt in, otherwise the connection stays plain. - 'Stream system audio' checkbox (greyed when sounddevice is unavailable) flows through to enable_audio. Viewer panel: - Host ID input that accepts '123 456 789' / '123-456-789' / etc. and uses parse_host_id to verify the announced ID after AUTH_OK. - Transport dropdown (TCP / WebSocket / TLS / WSS) plus a 'Skip cert verification' checkbox for self-signed deployments. WSS reuses the same SSLContext path; TLS/WSS hosts that present a real cert just uncheck the box. - 'Play received audio' checkbox spins up an AudioPlayer per session and routes incoming AUDIO frames to it via a Qt signal. - 'Push clipboard text' button sends the local clipboard to the host; incoming CLIPBOARD messages from the host are applied to the local clipboard and surfaced as a status line. - 'Send file...' opens a file picker + destination prompt and runs the upload on a QThread, with a QProgressBar bound to FileSender's progress events. - The frame display widget now accepts dragEnter/drop of local files; each dropped file kicks off the same upload flow. The receiver thread's host_id / clipboard / audio / file callbacks all marshal back to the GUI thread via Qt signals so the recv loop never touches widgets directly. Translations added for English, Traditional Chinese, Simplified Chinese, and Japanese. remote_desktop_tab.py is now ~950 lines, over CLAUDE.md's 750-line limit; splitting into

charset=UTF-8 Content-Transfer-Encoding: 8bit Round-up of every issue both scanners flagged on this branch: Library code: - Drop unused imports (NONCE_BYTES in host.py, dataclasses.field in file_transfer.py). - Replace the 17-parameter RemoteDesktopHost.__init__ with an AudioCaptureConfig dataclass (S107). GUI and tests now pass audio_config=AudioCaptureConfig(enabled=True, ...) instead of five separate kwargs, taking the parameter list down to 13. - Define module-level constants for repeated literals (S1192): _NOT_CONNECTED_MESSAGE in viewer.py, _OPEN_CLIPBOARD_FAILED in clipboard.py, _INVALID_TRANSFER_ID_MESSAGE in file_transfer.py. - Refactor RemoteDesktopViewer._recv_loop into a per-message dispatch table (S3776) — cognitive complexity 47 -> well under 15. - Float equality on host.py:638 sleep_for == 0.0 -> <= 0.0 (S1244). - Drop redundant exception classes from except tuples whenever a superclass is already listed (S5713). ConnectionError, ssl.SSLError and TimeoutError all derive from OSError. - ws_protocol.py: opposite-operator (S1940), reword 'commented-out' comment (S125), pass usedforsecurity=False on the SHA-1 used by the RFC 6455 handshake (Bandit B324 / Semgrep insecure-hash). - audio.py: replace the bare 'pass' in PortAudio's callback isolation with an explicit return + nosec B110 annotation. - All ssl.SSLContext(...) calls now set minimum_version = TLSv1_2 (S4423). User-opt-in insecure flows for self-signed certs are marked NOSONAR S5527/S4830 with a brief reason instead of changing behaviour. GUI: - Drop unused imports (os, QClipboard, QApplication, send_file). - Extract a _scroll_amount(angle_delta) helper to flatten the nested ternary on _FrameDisplay.wheelEvent (S3358). Tests: - Optional[_FakeStream] type hints (S5890); NOSONAR S100 on the two PascalCase mock methods that mirror the sounddevice API. - Replace bare 'pass' on the failure-stub stop() with an explanatory return (S1186). - NOSONAR S5655 on intentional bad-type tests for encode_text and dispatch_input. - Rename the unused 'tid' tuple element to '_tid' (S1481). - flow_control test: assert len + value before isinstance check so Sonar's flow analysis can prove seen[0] is safe (S6466). Behaviour is unchanged; tests still 295 pass on Windows. --- je_auto_control/gui/remote_desktop_tab.py | 40 +++-- je_auto_control/utils/clipboard/clipboard.py | 8 +- je_auto_control/utils/remote_desktop/audio.py | 16 +- .../utils/remote_desktop/file_transfer.py | 14 +- je_auto_control/utils/remote_desktop/host.py | 50 +++---- .../utils/remote_desktop/viewer.py | 137 +++++++++++------- .../utils/remote_desktop/ws_protocol.py | 13 +- .../flow_control/test_flow_control.py | 3 +- .../headless/test_remote_desktop_audio.py | 18 ++- .../headless/test_remote_desktop_clipboard.py | 2 +- .../test_remote_desktop_file_transfer.py | 2 +- .../test_remote_desktop_input_dispatch.py | 2 +- .../headless/test_remote_desktop_tls.py | 4 + 13 files changed, 191 insertions(+), 118 deletions(-) diff --git a/je_auto_control/gui/remote_desktop_tab.py b/je_auto_control/gui/remote_desktop_tab.py index 47620af3..a66ccf0a 100644 --- a/je_auto_control/gui/remote_desktop_tab.py +++ b/je_auto_control/gui/remote_desktop_tab.py @@ -13,7 +13,6 @@ original remote-screen pixel space using the latest received frame's size.

Drop AudioBackendError from except tuples that already catch RuntimeError; AudioBackendError is a RuntimeError subclass (S5713 ×4 in host.py and remote_desktop_tab.py). - Remove the now-unused AudioBackendError, _AUDIO_BLOCK_FRAMES, _AUDIO_CHANNELS, _AUDIO_SAMPLE_RATE imports from host.py and tab.py (Codacy F401). - Move NOSONAR S5527 / S4830 onto the actual ctx.check_hostname / ctx.verify_mode lines in remote_desktop_tab.py and the TLS test; Sonar only honours suppression when the comment is on the flagged line itself. - Replace '/tmp/...' literals in test_remote_desktop_file_transfer.py with relative 'drop/...' paths so Sonar's S5443 publicly-writable directory hotspot stops firing on what was always pure in-memory test data. - Add a 'nosemgrep:' annotation alongside the existing 'nosec B324' on the RFC 6455 SHA-1 line so Codacy's Semgrep ruleset stops flagging it. --- .idea/workspace.xml | 24 +------------------ je_auto_control/gui/remote_desktop_tab.py | 13 +++++----- je_auto_control/utils/remote_desktop/host.py | 9 +++---- .../utils/remote_desktop/ws_protocol.py | 1 + .../test_remote_desktop_file_transfer.py | 6 ++--- .../headless/test_remote_desktop_tls.py | 6 ++--- 6 files changed, 17 insertions(+), 42 deletions(-) diff --git a/.idea/workspace.xml b/.idea/workspace.xml index 0f6b65a8..50980db1 100644 --- a/.idea/workspace.xml +++ b/.idea/workspace.xml @@ -4,29 +4,7 @@
