| Description |
|
If client drops connection to the server, mongoc_collection_find() returns empty cursor as if no documents match the query, rather than signalling an error. Logs show "WARNING: stream: Failure to buffer 4 bytes: Failed to buffer 4 bytes within 300000 milliseconds," but this is not passed up to the application level. |

My error. I was calling mongoc_cursor_error() before calling mongoc_cursor_more() && mongoc_cursor_next(). Checking for an error after trying to read the cursor does detect dropped connection. Not sure how to close this issue. |
