From 60464eb72c03efedb9836983cb66a7ffc37afc9c Mon Sep 17 00:00:00 2001 From: Jonathan Druart Date: Tue, 20 Jan 2015 15:28:56 +0100 Subject: [PATCH] Bug 13601: Make dt_from_string not using DateTime::Format::DateParse For a couple of reasons, dt_from_string should not use DateTime::Format::DateParse: 1/ It does not manage date < 1900, certainly caused by l.47 of this module: $p{ year } = $year ? $year + 1900 : DateTime->now->year; 2/ It considers 31/01/2015 as a valid us date, which is not. Test plan: 1/ Verify that prove t/DateUtils.t returns green 2/ Play with dates in Koha (yes I know, it's vague...) 3/ Try to find a regression with dates 4/ Create a date with year <= 1900 and confirm it works QA comment: Why the sql format switch was: - $date_string =~ -s/(\d{4})(\d{2})(\d{2})\s+(\d{2})(\d{2})(\d{2})/$1-$2-$3T$4:$5:$6/; From where a date like "yyyymmdd hhmmss" can come? --- Koha/DateUtils.pm | 145 ++++++++++++++++++++++++++++++++++++------------------ 1 file changed, 97 insertions(+), 48 deletions(-) diff --git a/Koha/DateUtils.pm b/Koha/DateUtils.pm index 61877b9..0a5e15a 100644 --- a/Koha/DateUtils.pm +++ b/Koha/DateUtils.pm @@ -20,7 +20,6 @@ use strict; use warnings; use 5.010; use DateTime; -use DateTime::Format::DateParse; use C4::Context; use base 'Exporter'; @@ -54,56 +53,106 @@ to the system preferences.
