From 5640d280aa1b6370fbb209da0c0b662bdcac151c Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Tom=C3=A1s=20Cohen=20Arazi?= Date: Tue, 30 Sep 2025 15:47:35 -0300 Subject: [PATCH] Bug 40915: Add comprehensive regression tests for SIP MsgType message parsing and debug logging MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
