Bug: Chat atomic write path malformed — temp dir under .json/ #1049
Description
Activity
Closing as duplicate of #1051, which was fixed in PR #1065 (commit e034d3d).
Root cause:
tempfile.mkstemppositional args were(dir_path, prefix, suffix)instead of(suffix, prefix, dir_path), causing the dir path to be used as suffix and ".json" as the directory — producing invalid temp paths like.json/.tmp_chat_*.Fix: Already merged — corrected argument order to
mkstemp(".json", ".tmp_chat_", dir_path).
Problem
Chat history atomic writes fail with malformed temp directory path:
The path
/opt/autobot/autobot-backend/.json/.tmp_chat_*data/chatsis wrong —.jsonshould not be a directory in the path. Falls back to direct write (non-atomic), risking data corruption on concurrent writes.Discovered During
Backend log analysis during 502 debugging session.
Impact
Medium — non-atomic writes risk chat data corruption under concurrent saves. Currently masked by fallback.
