From 26369bbebf86570fad64032a7121a476019eb7f3 Mon Sep 17 00:00:00 2001 From: Yasuo Honda Date: Tue, 23 Oct 2018 07:29:26 +0000 Subject: MySQL 8.0.13 raises `ER_NO_REFERENCED_ROW` and `ER_ROW_IS_REFERENCED` when user has no parent table access privileges Refer https://dev.mysql.com/doc/relnotes/mysql/8.0/en/news-8-0-13.html#mysqld-8-0-13-errors >> * Previously, the ER_NO_REFERENCED_ROW_2 and ER_ROW_IS_REFERENCED_2 error messages for foreign key operations were displayed and revealed information about parent tables, even when the user had no parent table access privileges. Error handling for this situation has been revised: * If the user does have table-level privileges for all parent tables, ER_NO_REFERENCED_ROW_2 and ER_ROW_IS_REFERENCED_2 are displayed, the same as before. * If the user does not have table-level privileges for all parent tables, more generic error messages are displayed instead (ER_NO_REFERENCED_ROW and ER_ROW_IS_REFERENCED). << This pull request addresses these 3 failures: ```ruby $ ARCONN=mysql2 bundle exec ruby -w -Itest test/cases/adapter_test.rb -n /foreign/ Using mysql2 Run options: -n /foreign/ --seed 14251 F Failure: ActiveRecord::AdapterForeignKeyTest#test_foreign_key_violations_are_translated_to_specific_exception_with_validate_false [test/cases/adapter_test.rb:348]: [ActiveRecord::InvalidForeignKey] exception expected, not Class: Message: <"Mysql2::Error: Cannot add or update a child row: a foreign key constraint fails: INSERT INTO `fk_test_has_fk` (`fk_id`) VALUES (1231231231)"> ... snip ... rails test test/cases/adapter_test.rb:343 F Failure: ActiveRecord::AdapterForeignKeyTest#test_foreign_key_violations_on_delete_are_translated_to_specific_exception [test/cases/adapter_test.rb:368]: [ActiveRecord::InvalidForeignKey] exception expected, not Class: Message: <"Mysql2::Error: Cannot delete or update a parent row: a foreign key constraint fails: DELETE FROM fk_test_has_pk WHERE pk_id = 1"> ... snip ... rails test test/cases/adapter_test.rb:365 F Failure: ActiveRecord::AdapterForeignKeyTest#test_foreign_key_violations_on_insert_are_translated_to_specific_exception [test/cases/adapter_test.rb:358]: [ActiveRecord::InvalidForeignKey] exception expected, not Class: Message: <"Mysql2::Error: Cannot add or update a child row: a foreign key constraint fails: INSERT INTO fk_test_has_fk (fk_id) VALUES (0)"> ... snip ... rails test test/cases/adapter_test.rb:357 Finished in 0.087370s, 34.3366 runs/s, 34.3366 assertions/s. 3 runs, 3 assertions, 3 failures, 0 errors, 0 skips $ ``` --- .../lib/active_record/connection_adapters/abstract_mysql_adapter.rb | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/activerecord/lib/active_record/connection_adapters/abstract_mysql_adapter.rb b/activerecord/lib/active_record/connection_adapters/abstract_mysql_adapter.rb index cb5eeb64dd..0f73641369 100644 --- a/activerecord/lib/active_record/connection_adapters/abstract_mysql_adapter.rb +++ b/activerecord/lib/active_record/connection_adapters/abstract_mysql_adapter.rb @@ -624,6 +624,8 @@ module ActiveRecord # See https://dev.mysql.com/doc/refman/5.7/en/error-messages-server.html ER_DUP_ENTRY = 1062 ER_NOT_NULL_VIOLATION = 1048 + ER_NO_REFERENCED_ROW = 1216 + ER_ROW_IS_REFERENCED = 1217 ER_DO_NOT_HAVE_DEFAULT = 1364 ER_ROW_IS_REFERENCED_2 = 1451 ER_NO_REFERENCED_ROW_2 = 1452 @@ -640,7 +642,7 @@ module ActiveRecord case error_number(exception) when ER_DUP_ENTRY RecordNotUnique.new(message) - when ER_ROW_IS_REFERENCED_2, ER_NO_REFERENCED_ROW_2 + when ER_NO_REFERENCED_ROW, ER_ROW_IS_REFERENCED, ER_ROW_IS_REFERENCED_2, ER_NO_REFERENCED_ROW_2 InvalidForeignKey.new(message) when ER_CANNOT_ADD_FOREIGN mismatched_foreign_key(message) -- cgit v1.2.3
