From 5efae35a78b7cf6159613cae607c02945d3087a9 Mon Sep 17 00:00:00 2001 From: Martin Renvoize Date: Fri, 3 Apr 2020 11:16:39 +0100 Subject: [PATCH] Bug 25040: monkeypatch Schema::Loader for recent MariaDB Recent versions of MariaDB changed the output of 'DESCRIBE' for timestamp columns with defaults from `CURRENT_TIMESTAMP` to `current_timestamp()`. As such the code inside DBIx::Class::Schema::Loader which catches such cases and outputs `\"current_timestamp"` as a sensible cross platform default is missed and this leads of inconsistent class files and bugs with out default lookup code in Koha::Objects. This patch serves as a backport of the code I have submitted upstream such that out developers can continue to use update_dbix_class_files.pl to build their schema classes from the database and regardless of their db server version get a consistently correct output.
