This commit introduces Phase 1 of Slack connector enhancements, providing more granular control over the indexing process.
Key changes include:
1. **Updated Connector Configuration Schema (`search_source_connector.py`):**
* Added new fields to `SearchSourceConnector.config` for Slack:
* `slack_membership_filter_type`: ("all_member_channels", "selected_member_channels")
* `slack_selected_channel_ids`: List of channel IDs for selective indexing.
* `slack_indexing_frequency`: For periodic re-indexing schedule.
* `slack_initial_indexing_days`: Depth for initial message import.
* `slack_initial_max_messages_per_channel`: Max messages for initial import.
* Updated Pydantic validation logic for these new fields.
2. **Modified Indexing Task (`connectors_indexing_tasks.py`):**
* `index_slack_messages` now reads and utilizes the new configuration fields.
* Channel filtering is applied based on `slack_membership_filter_type` and `slack_selected_channel_ids`.
* Initial indexing runs use `slack_initial_indexing_days` and `slack_initial_max_messages_per_channel` to determine the scope of the first message fetch.
* The Slack API call was changed from `get_history_by_date_range` to a direct call to `get_conversation_history` using more precise timestamp-based parameters (`oldest`, `latest`) and message limits.
3. **New API Endpoint for Channel Discovery (`search_source_connectors_routes.py`):**
* Added `GET /connectors/slack/{connector_id}/discover-channels`.
* This endpoint allows the frontend to fetch a list of channels where the bot is currently a member, facilitating your selection for indexing.
4. **New API Endpoint for Specific Channel Re-index Trigger (`search_source_connectors_routes.py`):**
* Added `POST /slack/{connector_id}/reindex-channels`.
* This endpoint is structured to accept a list of channel IDs for targeted re-indexing.
* Note: The underlying modification to `index_slack_messages` to fully handle the specialized logic for these targeted re-indexes (ignoring last_indexed_at, etc.) was not completed. This endpoint sets up the route and request model.
These changes lay the backend foundation for a more configurable and user-friendly Slack integration. Frontend implementation for these configurations and the completion of the specific channel re-indexing logic are pending.
