From: Peter Rabbitson Date: Fri, 18 Jul 2014 16:21:20 +0000 (+0200) Subject: Standardize the Moo import block, move quote_sub/qsub into ::_Util X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=7f9a3f70074c5d4eb4e8260648f055b7556a7a4f;p=dbsrgits%2FDBIx-Class-Historic.git Standardize the Moo import block, move quote_sub/qsub into ::_Util This way we will have less boilerplate in subsequent commits where we will use quote_sub standalone Add yet another test to make absolutely sure quote_sub won't leak any of the strictures insanity --- diff --git a/lib/DBIx/Class/Storage/BlockRunner.pm b/lib/DBIx/Class/Storage/BlockRunner.pm index 70ded7e..d65595c 100644 --- a/lib/DBIx/Class/Storage/BlockRunner.pm +++ b/lib/DBIx/Class/Storage/BlockRunner.pm @@ -1,22 +1,26 @@ package # hide from pause until we figure it all out DBIx::Class::Storage::BlockRunner;
