From 30b37647107413281013396c0157c808c8498c06 Mon Sep 17 00:00:00 2001 From: Thomas Farstrike Date: Fri, 23 Jan 2026 15:31:47 +0100 Subject: [PATCH] Harmonize frameworks MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit All frameworks now follow the same singleton class pattern with class methods: AudioFlinger (already had this pattern) DownloadManager (refactored) ConnectivityManager (refactored) CameraManager (refactored) SensorManager (refactored) Pattern Structure: class FrameworkName: _initialized = False _instance_data = {} @classmethod def init(cls, *args, **kwargs): """Initialize the framework""" cls._initialized = True # initialization logic @classmethod def is_available(cls): """Check if framework is available""" return cls._initialized @classmethod def method_name(cls, *args): """Framework methods as class methods""" # implementation 2. Standardized Imports in __init__.py All frameworks are now imported consistently as classes: from .content.package_manager import PackageManager from .config import SharedPreferences from .net.connectivity_manager import ConnectivityManager from .net.wifi_service import WifiService from .audio.audioflinger import AudioFlinger from .net.download_manager import DownloadManager from .task_manager import TaskManager from .camera_manager import CameraManager from .sensor_manager import SensorManager 3. Updated Board Initialization Files Fixed imports in all board files to use the new class-based pattern: linux.py fri3d_2024.py fri3d_2026.py waveshare_esp32_s3_touch_lcd_2.py 4. Updated UI Components Fixed topmenu.py to import SensorManager as a class instead of a module. 5. Benefits of This Harmonization ✅ Consistency: All frameworks follow the same pattern - no more mixing of module imports and class imports ✅ Simplicity: Single, clear way to use frameworks - always as classes with class methods ✅ Functionality: All frameworks work identically - init(), is_available(), and other methods are consistent ✅ Maintainability: New developers see one pattern to follow across all frameworks ✅ No Breaking Changes: Apps continue to work without modification (Quasi apps, Lightning Piggy, etc.) 6. Testing All tests pass successfully, confirming: Framework initialization works correctly Board hardware detection functions properly UI components render without errors No regressions in existing functionality The harmonization is complete and production-ready. All frameworks now provide a unified, predictable interface that's easy to understand and extend. --- .../apps/com.micropythonos.imu/assets/imu.py | 2 +- .../assets/osupdate.py | 12 +- .../assets/calibrate_imu.py | 2 +- .../assets/check_imu_calibration.py | 2 +- .../com.micropythonos.wifi/assets/wifi.py | 3 +- internal_filesystem/lib/mpos/__init__.py | 14 +- .../lib/mpos/board/fri3d_2024.py | 2 +- .../lib/mpos/board/fri3d_2026.py | 2 +- internal_filesystem/lib/mpos/board/linux.py | 4 +- .../board/waveshare_esp32_s3_touch_lcd_2.py | 4 +- .../lib/mpos/camera_manager.py | 224 ++-- .../lib/mpos/net/connectivity_manager.py | 44 +- .../lib/mpos/net/download_manager.py | 1043 +++++++++------ .../lib/mpos/sensor_manager.py | 1149 +++++++++-------- .../lib/mpos/ui/setting_activity.py | 2 +- internal_filesystem/lib/mpos/ui/topmenu.py | 2 +- tests/test_calibration_check_bug.py | 2 +- tests/test_camera_manager.py | 2 +- tests/test_download_manager.py | 130 +- tests/test_osupdate.py | 101 +- tests/test_sensor_manager.py | 65 +- 21 files changed, 1666 insertions(+), 1145 deletions(-) diff --git a/internal_filesystem/apps/com.micropythonos.imu/assets/imu.py b/internal_filesystem/apps/com.micropythonos.imu/assets/imu.py index fb7fdda1..7679758e 100644 --- a/internal_filesystem/apps/com.micropythonos.imu/assets/imu.py +++ b/internal_filesystem/apps/com.micropythonos.imu/assets/imu.py @@ -1,4 +1,4 @@ -from mpos import Activity, sensor_manager as SensorManager +from mpos import Activity, SensorManager class IMU(Activity): diff --git a/internal_filesystem/builtin/apps/com.micropythonos.osupdate/assets/osupdate.py b/internal_filesystem/builtin/apps/com.micropythonos.osupdate/assets/osupdate.py index 86018e1a..2d0562c2 100644 --- a/internal_filesystem/builtin/apps/com.micropythonos.osupdate/assets/osupdate.py +++ b/internal_filesystem/builtin/apps/com.micropythonos.osupdate/assets/osupdate.py @@ -133,12 +133,12 @@ class OSUpdate(Activity): if self.current_state == UpdateState.IDLE or self.current_state == UpdateState.WAITING_WIFI: # Was waiting for network, now can check for updates self.set_state(UpdateState.CHECKING_UPDATE) - self.show_update_info() + TaskManager.create_task(self.show_update_info()) elif self.current_state == UpdateState.ERROR: # Was in error state (possibly network error), retry now that network is back print("OSUpdate: Retrying update check after network came back online") self.set_state(UpdateState.CHECKING_UPDATE) - self.show_update_info() + TaskManager.create_task(self.show_update_info()) elif self.current_state == UpdateState.DOWNLOAD_PAUSED: # Download was paused, will auto-resume in download thread pass @@ -425,11 +425,11 @@ class UpdateDownloader: Args: partition_module: ESP32 Partition module (defaults to esp32.Partition if available) connectivity_manager: ConnectivityManager instance for checking network during download - download_manager: DownloadManager module for async downloads (defaults to mpos.DownloadManager) + download_manager: DownloadManager instance for async downloads (defaults to DownloadManager class) """ self.partition_module = partition_module self.connectivity_manager = connectivity_manager - self.download_manager = download_manager # For testing injection + self.download_manager = download_manager if download_manager else DownloadManager self.simulate = False # Download state for pause/resume @@ -576,7 +576,7 @@ class UpdateDownloader: print(f"UpdateDownloader: Resuming from byte {self.bytes_written_so_far} (last complete block)") # Get the download manager (use injected one for testing, or global) - dm = self.download_manager if self.download_manager else DownloadManager + dm = self.download_manager # Create wrapper for chunk callback that checks should_continue async def chunk_handler(chunk): @@ -694,7 +694,7 @@ class UpdateChecker: """Initialize with optional dependency injection for testing.
