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.
I modified the Slack indexing process in `index_slack_messages` to skip any channel (public or private) where the bot's `is_member` status is false.
Previously, the indexing process would only explicitly skip private channels where the bot was not a member. For public channels, it would attempt to fetch history, relying on a `not_in_channel` error during history fetching to implicitly skip.
This change makes the skipping behavior explicit for all channel types based on the `is_member` flag retrieved from `conversations.list` API call. This aims to reduce unnecessary API calls to `conversations.history` for channels the bot hasn't been invited to, potentially speeding up the indexing process and avoiding hitting rate limits unnecessarily.
The `is_member` flag is reliably provided by the `SlackHistory.get_all_channels` method. Logging messages have been updated to reflect this change.
Here's a rundown of what I did:
Fix: Robust Slack rate limiting, error handling & GitHub org repos
This update delivers comprehensive improvements to Slack connector stability and enhances the GitHub connector.
**Slack Connector (`slack_history.py`, `connectors_indexing_tasks.py`):**
- I've implemented proactive delays (1.2s for `conversations.history`, 3s for `conversations.list` pagination) and `Retry-After` header handling for 429 rate limit errors across `conversations.list`, `conversations.history`, and `users.info` API calls.
- I'll now gracefully handle `not_in_channel` errors when fetching conversation history by logging a warning and skipping the channel.
- I've refactored channel info fetching: `get_all_channels` now returns richer channel data (including `is_member`, `is_private`).
- I've removed direct calls to `conversations.info` from `connectors_indexing_tasks.py`, using the richer data from `get_all_channels` instead, to prevent associated rate limits.
- I corrected a `SyntaxError` (non-printable character) in `slack_history.py`.
- I've enhanced logging for rate limit actions, delays, and errors.
- I've updated unit tests in `test_slack_history.py` to cover all new logic.
**GitHub Connector (`github_connector.py`):**
- I've modified `get_user_repositories` to fetch all repositories accessible by you (owned, collaborated, organization) by changing the API call parameter from `type='owner'` to `type='all'`.
- I've included unit tests in `test_github_connector.py` for this change.
- Added support for processing YouTube videos, including transcript extraction and document creation.
- Implemented a new background task for adding YouTube video documents.
- Enhanced the connector service to search for YouTube videos and return relevant results.
- Updated frontend components to include YouTube video options in the dashboard and connector sources.
- Added necessary dependencies for YouTube transcript API.
