From 0071d0451ac11f3cccfa28f06aab78c9cec9cd2d Mon Sep 17 00:00:00 2001 From: Tomas Cohen Arazi Date: Wed, 20 Aug 2014 00:33:40 -0300 Subject: [PATCH] Bub 12788: (regression test) refactor facet extraction code to allow testing This patch refactors the facet extraction loop into a proper function. The loop is changed so the MARC::Record objects are created only once instead of the old/current behaviour: once for each defined facet (in C4::Koha::getFacets). To test: - Apply the patch => SUCCESS: verify facets functionality remains unchanged. - Run: $ prove -v t/db_dependent/Search.t => SUCCESS: tests for _get_facets_data_from_record fail, because 100$a is considered for fields with indicator 1=z (field added by IncludeSeeFromInSearches syspref). - Sign off :-D Sponsored-by: Universidad Nacional de Cordoba Signed-off-by: Nick Clemens --- C4/Search.pm | 104 ++++++++++++++++++++++++++++------------------ t/db_dependent/Search.t | 30 +++++++++++++- 2 files changed, 91 insertions(+), 43 deletions(-) diff --git a/C4/Search.pm b/C4/Search.pm index c704c63..9587f7d 100644 --- a/C4/Search.pm +++ b/C4/Search.pm @@ -340,8 +340,8 @@ sub getRecords { my $results_hashref = (); # Initialize variables for the faceted results objects - my $facets_counter = (); - my $facets_info = (); + my $facets_counter = {}; + my $facets_info = {}; my $facets = getFacets(); my $facets_maxrecs = C4::Context->preference('maxRecordsForFacets')||20; @@ -499,51 +499,29 @@ sub getRecords { } $results_hashref->{ $servers[ $i - 1 ] } = $results_hash; -# Fill the facets while we're looping, but only for the biblioserver and not for a scan + # Fill the facets while we're looping, but only for the + # biblioserver and not for a scan if ( !$scan && $servers[ $i - 1 ] =~ /biblioserver/ ) { - my $jmax = - $size > $facets_maxrecs ?
