It happens that librarians to save time open an authority editor by putting
in the URL, by hand, the authid prefixed, by mistake, with a blank (e.g.
.../authorities.pl?authid= 100 -- mind the space before 100). In
such a case the editor opens with the right auth record (i.e. 100) but,
after saving the record, the content of the authid MARC field (001 for
a standard MARC 21 installation) results modified and contains
additional initial blanks.
Moreover, if the heading (1XX field) was modified in the authority record
during such an edit, the changes will not propagate to the linked
bibliographic records. And won't in the future.
This is because in the authorities.pl script $authid is taken (and
continuously used) directly from CGI parameter, without any
validation and/or correction (line 540 in the current main branch).
Test plan:
==========
1. Open an auth record in the editor with an added space before
authid value, e.g.:
http://ktd:8081/cgi-bin/koha/authorities/detail.pl?authid= 100
Modify the heading field -- in the ktd data set:
150 Computerized typesetting
Save the record.
2. a) Open the record for editing again--see the space added before
the authid in field 001. Close the editor (with Cancel).
b) Try to go to the linked biblio records with Used in X records.
Note no results, if using ES.
c) Remove the space before authid (after an:) in the URL.
Go to the linked biblio records. See that the content of
the field controlled by the modified auth record did not
update.
3. Apply the patch; restart_all.
4. Repeat p. 1 and 2 with a different authid. Everything should
be OK now.
