From 4062116352e6136e846f8a1c0567323c2c122213 Mon Sep 17 00:00:00 2001 From: Nick Clemens Date: Fri, 4 Dec 2020 12:03:52 +0000 Subject: [PATCH] Bug 26457: Throw exception if update of issues table fails While this won't prevent the deadlock, it should catch the case where a deadlock causes the DB update to fail and provide feedback to the user and rollback the transaction I don't know how to trigger the deadlock, I can only confirm that we see it, and that this should catch it. To test: 1 - Apply patches 2 - Checkout several items to a patron 3 - Confirm that 'Renew all' feature continues to work as expected and all items are renewed Signed-off-by: David Nind Signed-off-by: Marcel de Rooy Signed-off-by: Jonathan Druart --- C4/Circulation.pm | 6 ++++++ Koha/Exceptions/Checkout.pm | 15 +++++++++++++++ svc/renew | 13 +++++++++++-- 3 files changed, 32 insertions(+), 2 deletions(-) create mode 100644 Koha/Exceptions/Checkout.pm diff --git a/C4/Circulation.pm b/C4/Circulation.pm index 5b5a0d2c23..92e284fa41 100644 --- a/C4/Circulation.pm +++ b/C4/Circulation.pm @@ -62,6 +62,7 @@ use Koha::Charges::Fees; use Koha::Config::SysPref; use Koha::Checkouts::ReturnClaims; use Koha::SearchEngine::Indexer; +use Koha::Exceptions::Checkout; use Carp; use List::MoreUtils qw( uniq any ); use Scalar::Util qw( looks_like_number ); @@ -3039,6 +3040,11 @@ sub AddRenewal { ); $sth->execute( $datedue->strftime('%Y-%m-%d %H:%M'), $renews, $unseen_renewals, $lastreneweddate, $borrowernumber, $itemnumber ); + if ( $sth->err ){ + Koha::Exceptions::Checkout::FailedRenewal->throw( + error => 'Update of issue# ' . $issue->issue_id .
