From 59b7744e1c14da3e9fcd662fd128957ac0d2bf13 Mon Sep 17 00:00:00 2001 From: =?utf8?q?St=C3=A9phane=20Delaune?= Date: Tue, 21 Oct 2014 18:05:18 +0200 Subject: [PATCH] Bug 13082: fix to prevent adding of invalid records in marc file Test: 1. Edit record, add 100.000 chars text to 500a 2. xml export produce the record, 3. mrc export do not produce the record, warning on log export.pl: Record length of 111000 is larger than the MARC spec allows (99999 bytes). at /usr/share/perl5/MARC/File/USMARC.pm line 314. record (number 139489) is invalid and therefore not exported because its reopening generates warnings above at... Signed-off-by: Frederic Demians I confirm that exporting biblio records larger than 10000 characters in ISO2709 produces invalid files. After applying this patch, the culprit record (too large, but also other inconsistencies preventing record parsing with MARC::File::USMARC) is not exported anymore. A warning is produced in Koha Apache log file. Warnings to the user on WUI would be better, but it isn't the case yet, so it isn't a regression. Signed-off-by: Katrin Fischer I agree that a visible warning/result message in the staff interface would be nice, but this works as described.
