From 5775df012701144a76eb96501336d53c61fb28a5 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Marko=20M=C3=A4kel=C3=A4?= Date: Sun, 10 Dec 2023 13:19:21 +0200 Subject: [PATCH] MDEV-20142 encryption.innodb_encrypt_temporary_tables fails The data type of the column INFORMATION_SCHEMA.GLOBAL_STATUS.VARIABLE_VALUE is a character string. Therefore, if we want to compare some values as integers, we must explicitly cast them to integer type, to avoid an awkward comparison where '10'<'9' because the first digit is smaller. --- .../r/innodb_encrypt_temporary_tables.result | 16 ++++++++++------ .../t/innodb_encrypt_temporary_tables.test | 12 ++++++++---- 2 files changed, 18 insertions(+), 10 deletions(-) diff --git a/mysql-test/suite/encryption/r/innodb_encrypt_temporary_tables.result b/mysql-test/suite/encryption/r/innodb_encrypt_temporary_tables.result index 541680ae862..d86ca6f9c00 100644 --- a/mysql-test/suite/encryption/r/innodb_encrypt_temporary_tables.result +++ b/mysql-test/suite/encryption/r/innodb_encrypt_temporary_tables.result @@ -1,6 +1,8 @@ -SELECT variable_value into @old_encrypted FROM information_schema.global_status +SELECT CAST(variable_value AS INT) INTO @old_encrypted +FROM information_schema.global_status WHERE variable_name = 'innodb_encryption_n_temp_blocks_encrypted'; -SELECT variable_value into @old_decrypted FROM information_schema.global_status +SELECT CAST(variable_value AS INT) INTO @old_decrypted +FROM information_schema.global_status WHERE variable_name = 'innodb_encryption_n_temp_blocks_decrypted'; CREATE TEMPORARY TABLE t1(f1 CHAR(200), f2 CHAR(200)) ENGINE=InnoDB; INSERT INTO t1 (f1,f2) SELECT '', '' FROM seq_1_to_8192; @@ -12,11 +14,13 @@ COUNT(*) SELECT COUNT(*) FROM t2; COUNT(*) 8192 -SELECT variable_value > @old_encrypted FROM information_schema.global_status +SELECT CAST(variable_value AS INT) > @old_encrypted +FROM information_schema.global_status WHERE variable_name = 'innodb_encryption_n_temp_blocks_encrypted'; -variable_value > @old_encrypted +CAST(variable_value AS INT) > @old_encrypted 1 -SELECT variable_value > @old_decrypted FROM information_schema.global_status +SELECT CAST(variable_value AS INT) > @old_decrypted +FROM information_schema.global_status WHERE variable_name = 'innodb_encryption_n_temp_blocks_decrypted'; -variable_value > @old_decrypted +CAST(variable_value AS INT) > @old_decrypted 1 diff --git a/mysql-test/suite/encryption/t/innodb_encrypt_temporary_tables.test b/mysql-test/suite/encryption/t/innodb_encrypt_temporary_tables.test index d99a55b9b44..83abb783c9e 100644 --- a/mysql-test/suite/encryption/t/innodb_encrypt_temporary_tables.test +++ b/mysql-test/suite/encryption/t/innodb_encrypt_temporary_tables.test @@ -2,10 +2,12 @@ --source include/have_innodb.inc --source include/have_file_key_management_plugin.inc -SELECT variable_value into @old_encrypted FROM information_schema.global_status +SELECT CAST(variable_value AS INT) INTO @old_encrypted +FROM information_schema.global_status WHERE variable_name = 'innodb_encryption_n_temp_blocks_encrypted'; -SELECT variable_value into @old_decrypted FROM information_schema.global_status +SELECT CAST(variable_value AS INT) INTO @old_decrypted +FROM information_schema.global_status WHERE variable_name = 'innodb_encryption_n_temp_blocks_decrypted'; CREATE TEMPORARY TABLE t1(f1 CHAR(200), f2 CHAR(200)) ENGINE=InnoDB; @@ -17,8 +19,10 @@ INSERT INTO t2 (f1,f2,f3) SELECT '', '', '' FROM seq_1_to_8192; SELECT COUNT(*) FROM t1; SELECT COUNT(*) FROM t2; -SELECT variable_value > @old_encrypted FROM information_schema.global_status +SELECT CAST(variable_value AS INT) > @old_encrypted +FROM information_schema.global_status WHERE variable_name = 'innodb_encryption_n_temp_blocks_encrypted'; -SELECT variable_value > @old_decrypted FROM information_schema.global_status +SELECT CAST(variable_value AS INT) > @old_decrypted +FROM information_schema.global_status WHERE variable_name = 'innodb_encryption_n_temp_blocks_decrypted';
