           Summary: link_bibs_to_authorities.pl --test updates auth_header
                    records with AutoAddAuthorites on
          Severity: normal
    Classification: Unclassified
                OS: All
          Reporter: matted-34813 at mypacks.net
          Hardware: All
            Status: NEW
           Version: master
         Component: Command-line Utilities
           Product: Koha

I noticed that when i ran link_bibs_to_authorites.pl with --test, it calls
LinkBibHeadingsToAuthorities in Biblio.pm, which if you have the
AutoAddAuthorities syspref enabled, calls AddAuthority, which results in
auth_header being inserted/updated.

So the --test option won't prevent updates.  This can burn someone if run in
production.

It correctly skips ModBiblio in the link_bibs_to_authorites.pl script.

I was doing a test run migration from 3.0 to pre-3.10 master(2012-10-10) and
had deleted all my auth_header records.  Of course after rebuilding my
biblio/auth zebra index (-b -a -r)  I ran the script with --test, but saw
auth_header records were added.

Since my library only had machine generated auth records, and I needed to clean
up duplicate authority records from 3.0 behaviors, I was taking this route
since no deduplication script exists, yet.
