http://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=10961 Bug ID: 10961 Summary: Error in GetMarcBiblio can cause severe data loss Change sponsored?: --- Product: Koha Version: master Hardware: All OS: All Status: NEW Severity: critical Priority: P5 - low Component: Architecture, internals, and plumbing Assignee: gmcharlt@gmail.com Reporter: kyle@bywatersolutions.com QA Contact: testopia@bugs.koha-community.org A bug in GetMarcBiblio can cause severe data loss if your database has records where the biblionumber and biblioitemnumber do not match and the script misc/batchRebuildBiblioTables.pl is run. The Biblio::GetMarcBiblio makes a kall to C4::Biblio::_koha_marc_update_bib_ids which passes the biblionumber as both the biblionumber *and the biblioitemnumber*. Thus, if your biblio and biblioitem numbers are not always equal, you will end up with a record where the biblioitemnumber is incorrect in the record! This is usually not a severe issue, but since batchRebuildBiblioTables uses that record to update the database tables, it ends up updating the wrong biblioitem row! -- You are receiving this mail because: You are watching all bug changes.
