I say this because it doesn't appear like we honor case sensitivity for barcodes elsewhere. So, to recreate: 1. Create an item give it a barcode like 'abc123'; 2. Try creating a 2nd item with a barcode: 'ABC123', you get an error 'Error saving item: Barcode must be unique.' 3. Checkin the item 'ABC123', the 'abc123' item successfully checks in. 4. The case doesn't seem to matter elsewhere in Koha ( check-in, checkout, searching, batch tools ) 5. Try the inventory tool and use 'ABC123'. The barcode is not found. If Koha treats 'ABC123' and 'abc123' the same when creating an item, it should probably treat them the same when using the inventory tool.
Created attachment 174638 [details] [review] Bug 38452: Add lc() for case insensitivity To test: 1. Create an item give it a barcode like 'abc123'; 2. Try creating a 2nd item with a barcode: 'ABC123', you get an error 'Error saving item: Barcode must be unique.' 3. Checkin the item 'ABC123', the 'abc123' item successfully checks in. 4. The case doesn't seem to matter elsewhere in Koha ( check-in, checkout, searching, batch tools ) 5. Try the inventory tool and use 'ABC123'. The barcode is not found. 6. APPLY PATCH, restart_all 7. Try the inventory tool again with both 'abc123' and 'ABC123', they should now both work.
