This causes message parsing failures and protocol errors in self-check systems. The previous regex only handled single carriage returns (\r), missing Windows CRLF (\r\n) and Unix LF (\n) sequences. This patch normalizes all line ending variations to spaces to prevent SIP message corruption while preserving message content. Test plan: 1. Go to a patron record and click "Add message" 2. Select "Add message for OPAC..." from dropdown 3. In a text editor (e.g., Word), create a message with line breaks: "This is line one[Enter]This is line two[Enter]This is line three" 4. Copy and paste this multi-line text into the message box and save 5. Run the SIP emulator: misc/sip_cli_emulator.pl 6. Execute a patron information request for this patron 7. Before patch: Observe message breaks at line endings, corrupting the SIP response 8. Apply patch and restart SIP server 9. Repeat steps 5-6 10. After patch: Verify the message appears as single line with spaces replacing line breaks: "This is line one This is line two This is line three" 11. Test with different line ending types (Windows, Mac, Unix) to ensure all variations are handled correctly Signed-off-by: Martin Renvoize <martin.renvoize@openfifth.co.uk> -- You are receiving this mail because: You are watching all bug changes.
