From fd532438668294144f281da4e283d796443c12df 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 - Confirm that 'Renew all' feature continues to work as expected --- C4/Circulation.pm | 8 +++++++- Koha/Exceptions/Checkout.pm | 15 +++++++++++++++ svc/renew | 13 +++++++++++-- 3 files changed, 33 insertions(+), 3 deletions(-) create mode 100644 Koha/Exceptions/Checkout.pm diff --git a/C4/Circulation.pm b/C4/Circulation.pm index 602bc54f6b..e067d306b7 100644 --- a/C4/Circulation.pm +++ b/C4/Circulation.pm @@ -59,6 +59,7 @@ use Koha::Charges::Fees; use Koha::Util::SystemPreferences; 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 ); @@ -3084,7 +3085,12 @@ sub AddRenewal { AND itemnumber=?" ); - $sth->execute( $datedue->strftime('%Y-%m-%d %H:%M'), $renews, $unseen_renewals, $lastreneweddate, $borrowernumber, $itemnumber ); + my $success =$sth->execute( $datedue->strftime('%Y-%m-%d %H:%M'), $renews, $unseen_renewals, $lastreneweddate, $borrowernumber, $itemnumber ); + unless ( $success ){ + Koha::Exceptions::Checkout::RenewalFailed->throw( + error => 'unable to update issue ' . $issue->issue_id + ); + } # Update the renewal count on the item, and tell zebra to reindex $renews = ( $item_object->renewals || 0 ) + 1; diff --git a/Koha/Exceptions/Checkout.pm b/Koha/Exceptions/Checkout.pm new file mode 100644 index 0000000000..ed4b0a5a27 --- /dev/null +++ b/Koha/Exceptions/Checkout.pm @@ -0,0 +1,15 @@ +package Koha::Exceptions::Checkout; + +use Modern::Perl; + +use Exception::Class ( + 'Koha::Exceptions::Checkout' => { + description => "Something went wrong!" + }, + 'Koha::Exceptions::Checkout::FailedRenewal' => { + isa => 'Koha::Exceptions::Checkout', + description => "Renewing checkout failed" + }, +); + +1; diff --git a/svc/renew b/svc/renew index e7792ddd60..9a890d77a7 100755 --- a/svc/renew +++ b/svc/renew @@ -21,6 +21,7 @@ use Modern::Perl; use CGI; use JSON qw(to_json); +use Try::Tiny; use C4::Circulation; use C4::Context; @@ -67,8 +68,16 @@ if ( $data->{error} && $data->{error} eq 'on_reserve' && C4::Context->preference } if ( $data->{renew_okay} ) { - $date_due = AddRenewal( $borrowernumber, $itemnumber, $branchcode, $date_due, undef, undef, $seen ); - $data->{date_due} = output_pref( { dt => $date_due, as_due_date => 1 } ); + try{ + $date_due = AddRenewal( $borrowernumber, $itemnumber, $branchcode, $date_due, undef, undef, $seen ); + $data->{date_due} = output_pref( { dt => $date_due, as_due_date => 1 } ); + } catch { + if ( ref($_) eq 'Koha::Exceptions::Checkout::RenewalFailed' ) { + $data->{error} = 'renewal_failed'; + } else { + $_->rethrow; + } + } } print to_json($data); -- 2.11.0
