When the Unstructured API returns a Table element without text_as_html
in its metadata (e.g. local install or free-tier API), the lambda was
raising KeyError: 'text_as_html', crashing the entire document
indexing pipeline for any file containing tables.
Guard the key access with .get() and fall back to the plain extracted
text content (x) so the pipeline continues and the table content is
still indexed, just without HTML formatting.
document_converters, the github size-fallback chunker, revert_service
restores, and the kb-persistence middleware now write explicit positions
(the middleware read path also orders by position).
- Added new environment variables for controlling task execution limits, including `SURFSENSE_SUBAGENT_INVOKE_TIMEOUT_SECONDS`, `SURFSENSE_TASK_BATCH_CONCURRENCY`, and `SURFSENSE_TASK_BATCH_MAX_SIZE`.
- Updated documentation to reflect new batch processing capabilities for `task` calls, allowing for concurrent execution of multiple subagent tasks.
- Improved error handling and receipt generation for deliverables, ensuring consistent feedback on task status.
- Refactored middleware to incorporate search space ID for better task management.
generate_document_summary and create_document_chunks are async helpers
called from the chat path and from many connector indexers. Both wrapped
embed_text/embed_texts directly inside the coroutine, blocking the event
loop for the full duration of the embedding call.
- Added a reentrant lock to ensure thread-safe access to the tokenizer and embedding model, preventing runtime errors during concurrent operations.
- Updated the `truncate_for_embedding` and `embed_text` functions to utilize the lock, ensuring safe execution in multi-threaded environments.
- Enhanced the `embed_texts` function to maintain thread safety while processing multiple texts for embedding.
- Added endpoint to list agent tools with metadata, excluding hidden tools.
- Updated NewChatRequest and RegenerateRequest schemas to include disabled tools.
- Integrated disabled tools management in the NewChatPage and Composer components.
- Improved tool instructions and visibility in the system prompt.
- Refactored tool registration to support hidden tools and default enabled states.
- Enhanced document chunk creation to handle strict zip behavior.
- Cleaned up imports and formatting across various files for consistency.
- Replaced direct embedding calls with a utility function across various components to streamline embedding logic.
- Added enable_summary flag to several models and routes to control summary generation behavior.
