Bug 40915: Add comprehensive regression tests for SIP MsgType message parsing and debug logging
These tests verify that C4::SIP::Sip::MsgType correctly parses SIP messages without
creating problematic arrayref field values, and validates enhanced debug logging for
empty critical fields.
Test Coverage:
• Message parsing with correct protocol versions (PATRON_INFO/HOLD/RENEW use v2, CHECKOUT
uses v1)
• Empty patron_id and item_id field detection with debug logging
• Malformed delimiter handling (double delimiters, trailing empty fields)
• Multiple consecutive empty fields in single message
• Confusing delimiter patterns that could break parsing
• Verification that parsed fields are strings, not arrayrefs
• Working siplog mock infrastructure in C4::SIP::Sip::MsgType
Arrayref Prevention Tests:
Tests verify message parsing DOESN'T create empty arrayrefs that would later cause "Odd
number of elements in anonymous hash" errors when passed to Koha::Objects->find()
operations.
Enhanced Debug Logging Tests:
Tests validate that empty critical fields (patron_id, item_id) are detected during
parsing and generate appropriate debug messages to help troubleshoot downstream
constraint errors.
