v10.4.1 - Time Expression Parsing Fix

on GitHub

🔧 Bug Fix Release

Fixed

• Time Expression Parsing (Issue #396): Fixed time_expr parameter to correctly parse natural language time expressions
  • Now correctly handles: "last week", "3 days ago", "last 5 days", "1 week ago"
  • Changed from extract_time_expression() to parse_time_expression() in search_memories()
  • Added comprehensive regression tests covering reported failures and edge cases
  • ISO date workaround (after/before parameters) continues to work as before

What was broken?

The time_expr parameter in memory_search was failing for most natural language expressions:

• ❌ "last week" - returned empty results
• ❌ "3 days ago" - returned empty results
• ❌ "last 5 days" - returned error
• ✅ "yesterday" - worked (by coincidence)

What is fixed?

All natural language time expressions now work correctly:

• ✅ "last week" - returns memories from previous Monday-Sunday
• ✅ "3 days ago" - returns memories from exactly 3 days ago
• ✅ "last 5 days" - returns memories from last 5 days
• ✅ "1 week ago" - returns memories from 7 days ago

Testing

• 2 new comprehensive test functions added in tests/test_issue_396.py
• All existing tests continue to pass
• Regression coverage for reported issues and edge cases

Risk Assessment

Risk Level: LOW

• Single-line function change
• Well-tested time parser functions (14 existing tests + 2 new tests)
• No breaking changes to API
