From 1fd8c8a4debf750476a2369e4440ac662b19f6b7 Mon Sep 17 00:00:00 2001 From: Paul Poulain Date: Wed, 1 Feb 2012 15:15:02 +0100 Subject: [PATCH] Bug 7246 add offset/length and where options to rebuild_zebra This patch reimplement a feature that is on biblibre/master for Koha-community/master It adds 4 parameters: * offset = the offset of record. Say 1000 to start rebuilding at the 1000th record of your database * length = how many records to export. Say 400 to export only 400 records * where = add a where clause to rebuild only a given itemtype, or anything you want to filter on Another improvement resulting from offset & length limit is the rebuild_zebra_sliced.zsh that will be submitted in another patch. rebuild_zebra_sliced will slice your all database in small chunks, and, if something went wrong for a given slice, will slice the slice, and repeat, until you reach a slice size of 1, showing which record is wrong in your database. Signed-off-by: Jared Camins-Esakov Removed mention of -l option for limiting number of items exported, as requested by QA manager. This can be re-added in a later patch.
