From 63e926c5d87a605568b8b652da7788343b828df6 Mon Sep 17 00:00:00 2001 From: Jonathan Druart Date: Wed, 29 Jul 2020 11:17:34 +0200 Subject: [PATCH] Bug 26080: Use the task queue for batch delete biblios This patch takes advantage of the task queue to delegate the batch delete biblios tool. Test plan: Delete bibliographic records using the batch record deletion tool Confirm that the job is now delegated to the task queue and that everything else is working as before --- Koha/BackgroundJob.pm | 3 + Koha/BackgroundJob/BatchDeleteBiblio.pm | 158 ++++++++++++++++++ .../prog/en/modules/admin/background_jobs.tt | 44 +++++ .../en/modules/tools/batch_delete_records.tt | 18 +- misc/background_jobs_worker.pl | 6 +- tools/batch_delete_records.pl | 137 +++------------ 6 files changed, 241 insertions(+), 125 deletions(-) create mode 100644 Koha/BackgroundJob/BatchDeleteBiblio.pm diff --git a/Koha/BackgroundJob.pm b/Koha/BackgroundJob.pm index d4d4c2a59e..07a71ff71f 100644 --- a/Koha/BackgroundJob.pm +++ b/Koha/BackgroundJob.pm @@ -10,6 +10,7 @@ use Koha::DateUtils qw( dt_from_string ); use Koha::Exceptions; use Koha::BackgroundJob::BatchUpdateBiblio; use Koha::BackgroundJob::BatchUpdateAuthority; +use Koha::BackgroundJob::BatchDeleteBiblio; use Scalar::Util qw( weaken ); @@ -71,6 +72,8 @@ sub process { ?
