Add Plugin Reload Feature Without Restarting DataLab #110

Description

Summary

Currently, plugins in DataLab require a full application restart to be reloaded, which disrupts workflows and reduces efficiency. This issue proposes adding a feature to reload plugins dynamically without needing to restart DataLab.


Proposed Solution

  1. Dynamic Plugin Management

    • Implement a mechanism to unload and reload plugins at runtime.
    • Ensure that plugin resources (e.g., UI components, data structures) are properly disposed of to avoid memory leaks.
  2. Reload UI Integration

    • Add a "Reload Plugins" option in the settings or tools menu for user convenience.
    • Provide feedback to users via notifications or status messages indicating success or failure of plugin reloads.
  3. Error Handling

    • Handle cases where a plugin fails to reload due to missing dependencies or errors in the plugin code:
      • Log detailed error messages.
      • Optionally allow the user to skip problematic plugins.

Benefits

  • Improves user productivity by eliminating the need to restart DataLab for plugin updates.
  • Enhances the plugin development workflow by providing a smoother testing process.
  • Reduces application downtime in multi-user or automation scenarios.

Suggested Priority

  • Critical:

    • Implement the basic reload mechanism.
    • Ensure resource cleanup and error handling during reloads.
  • Medium:

    • Integrate the feature into the user interface.
  • Optional:

    • Add file change detection.
    • Allow selective reloading of specific plugins.
    • Provide additional tools for debugging and monitoring plugin states.
