Description Nick Clemens 2020-11-02 11:26:58 UTC
Similar to bug 26781 when moving subfield 0 we move the whole record. 

The tests from 17510 actually cover this, but I suspect it is still not the desired/expected behavior

Bug 26894: Handle subfield 0 and delete empty fields

This patch corrects handling of subfield 0 when copying/moving. Before these
patches copying from subfield 0 would copy the entire field.

We also correct an error that if moving a single subfield, we can leave behind empty
fields with no subfields. They should be deleted.

To test:
1 - Define a new MARC Modification template with actions:
        Delete field 100$0
        Add new field 100$0 with value Test
        Update existing or add new field 100$0 with value TestUpdated
        Move field 100$0 to 600$0
        Copy field 600$0 to 100$0
        Copy and replace field 245$0 to 700$0
2 - Define a new record like:
    LDR 00334nam a22001217a 4500
    003 ff
    005 20201102111604.0

    245 _ _ ‡012345‡aThe aty of computer programming‡cDonald E. Knuth
    650 _ 0 ‡042‡aComputer programming‡9462
3 - Modify this record using the template above
4 - Note that entier 245 is copied to 700, same for 600 field
5 - Apply patch
6 - Now only subfields 0 are copied

Tested well.

Note that I was running manually misc/background_jobs_worker.pl, that must be restarted after applying patches.
