https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=40934 --- Comment #27 from Martin Renvoize (ashimema) <martin.renvoize@openfifth.co.uk> --- Created attachment 206109 --> https://bugs.koha-community.org/bugzilla3/attachment.cgi?id=206109&action=edit Bug 40934: (follow-up) Fix false positive on --code/--exclude-code mutual exclusivity The mutual-exclusivity check ran before the empty-element cleanup added for bug 37075, so a bare -c (no value) left an empty string in @letter_code, which the check saw as truthy and rejected even though -c had effectively not been used. Move the cleanup above the check. Also add the same mutual-exclusivity guard directly in C4::Letters::SendQueuedMessages, since letter_code and exclude_letter_code build the same search key and passing both would otherwise let one silently clobber the other in the hashref passed to ->search - only the CLI script enforced this until now, so any other caller could hit the silent-clobber bug. Adds regression coverage: unit tests for the new exception in SendQueuedMessages, and a script-level test reproducing the RM's reported false positive.
