From 900bfd94a9c3c45484d88aa69071b7a52c5b04b4 Mon Sep 17 00:00:00 2001 From: schneems Date: Fri, 14 Aug 2015 11:31:33 -0500 Subject: Prevent destructive action on production database This PR introduces a key/value type store to Active Record that can be used for storing internal values. It is an alternative implementation to #21237 cc @sgrif @matthewd. It is possible to run your tests against your production database by accident right now. While infrequently, but as an anecdotal data point, Heroku receives a non-trivial number of requests for a database restore due to this happening. In these cases the loss can be large. To prevent against running tests against production we can store the "environment" version that was used when migrating the database in a new internal table. Before executing tests we can see if the database is a listed in `protected_environments` and abort. There is a manual escape valve to force this check from happening with environment variable `DISABLE_DATABASE_ENVIRONMENT_CHECK=1`. --- activerecord/lib/active_record/schema_dumper.rb | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'activerecord/lib/active_record/schema_dumper.rb') diff --git a/activerecord/lib/active_record/schema_dumper.rb b/activerecord/lib/active_record/schema_dumper.rb index 2362dae9fc..65005bd44b 100644 --- a/activerecord/lib/active_record/schema_dumper.rb +++ b/activerecord/lib/active_record/schema_dumper.rb @@ -254,7 +254,7 @@ HEADER end def ignored?(table_name) - [ActiveRecord::Base.schema_migrations_table_name, ignore_tables].flatten.any? do |ignored| + [ActiveRecord::Base.schema_migrations_table_name, ActiveRecord::Base.internal_metadata_table_name, ignore_tables].flatten.any? do |ignored| ignored === remove_prefix_and_suffix(table_name) end end -- cgit v1.2.3
