I found a [minor?] problem with the 3.8.10 tarball on Ubuntu 12.04.2 LTS on my sandbox after restoring a 3.8.5 mysql dump from our production box, at which point 'installer' does its magic. All the biblios appear to transfer correctly ('mysql> select biblionumber from biblio;' gave identical results; same with author, etc.) The standard CRON job runs successfully. Problem: a small number of biblios "went missing" in 3.8.10. It *seemed* to be limited to 'serials' but I can't be sure, as I could only find them on a 'hit or miss basis' -- in fact I only found the first one accidentally: e.g. a biblio and three items for the serial Flugsport could not be found by title, by author, by Barcode, by author in authorities ... even "No results match your search for 'biblionumber=19762' in NMA Catalog." Yet, run a Koha report: SELECT * FROM biblioitems, biblio, items WHERE biblio.biblionumber=19762 AND biblioitems.biblionumber=19762 AND items.biblionumber=19762 and everything was there, including the blobs, MARC, XML ... A full c/l re-index -a -r -v and -b -r -v -x solves the problem. As I can reproduce this behaviour (by restoring the same dump) is there anything helpful that I could look into? Could this be related to Bug 9511? The fix does not appear to work for me, I've just updated bugzilla. Thanks - Paul
