📄 Description

Summary

Add pagination support to the /chats/all endpoint to prevent Out of Memory (OOM) errors for users with many chats.

Problem

Users with thousands of chats were experiencing OOM errors when the /chats/all endpoint tried to load all chats into memory at once (Issue #22206).

Solution

  • Add optional page and limit query parameters
  • Set a default limit of 1000 to prevent memory exhaustion
  • Maintain backward compatibility - response is still a list (not a paginated response object)
  • Users needing to export all chats can paginate through results

Changes

  • Modified get_user_chats in backend/open_webui/routers/chats.py
  • Added pagination logic with sensible defaults
  • Added docstring explaining the new parameters

Backward Compatibility

✅ Fully backward compatible - existing code using /chats/all will continue to work
✅ Response format unchanged (still returns a list)
✅ Only behavior change: capped at 1000 results to prevent OOM

Testing

  • Syntax validation passed
  • Logic follows existing pattern used in /chats/search endpoint

Fixes #22206
