In situation above old mechanism of detection matching definition in PS and current version always require reprepare and so prevent executing the PS. One work arount is to increase TDC, other - improve version check for views (which is done here). Now in suspiciouse cases we check MD5 of the view to be sure that version really have chenged. --- mysql-test/r/view.result | 28 ++++++++++++++++++++++++++++ mysql-test/t/view.test | 39 +++++++++++++++++++++++++++++++++++++++ sql/parse_file.cc | 17 +++++++++++++++++ sql/parse_file.h | 4 +++- sql/sql_view.cc | 41 +++++++++++++++++++++++++++++++++++++++++ sql/sql_view.h | 1 + sql/table.cc | 26 ++++++++++++++++++++++++++ sql/table.h | 8 +------- 8 files changed, 156 insertions(+), 8 deletions(-) diff --git a/mysql-test/r/view.result b/mysql-test/r/view.result index e8c96e49977..030d0f0c520 100644 --- a/mysql-test/r/view.result +++ b/mysql-test/r/view.result @@ -6259,5 +6259,33 @@ t1col1 t1col2 t1col3 drop view v1;

revision-id: 9c46adbb7e093029c56dddd5dbbef407db4e8160 (mariadb-10.1.37-7-g9c46adbb7e0) parent(s): ef40018535b71f0a4387fa6c1cc22e9991dfc0db author: Jan Lindström committer: Jan Lindström timestamp: 2018-11-12 12:05:42 +0200 message: MDEV-17229: Encryption threads ignore innodb_default_encryption_key_id Background MariaDB identifies encryption keys using a positive 32-bit integer. This makes it easier to identify the key you want to use for particular tables, through the ENCRYPTION_KEY_ID table option. You can set the default key using the innodb_default_encryption_key_id system variable. If no value is set system default (1) is used. Syntax SET [GLOBAL|SESSION] innodb-default-encryption-key-id=<key_id>; Used default encryption key_id can't be set to value that does not exists on encryption plugin. e.g. SET GLOBAL innodb_default_encryption_key_id = 999; ERROR 42000: Variable 'innodb_default_encryption_key_id' can't be set to the value of '999' SHOW WARNINGS; Level Code Message Warning 1210 InnoDB: innodb_default_encryption_key_id=999 not available in encryption plugin Error 1231 Variable 'innodb_default_encryption_key_id' can't be set to the value of '999' If variable is set on configuration file (my.cnf or similar) server will refuse to start if used key_id is not found from encryption plugin. This can be seen on server error log e.g. [ERROR] InnoDB: cannot use encryption as default encryption key_id 999 not found from encryption plugin. [ERROR] Plugin 'InnoDB' init function returned error. [ERROR] Plugin 'InnoDB' registration as a STORAGE ENGINE failed. If user creates a table that is not encrypted e.g: create table t1(a int) encrypted=no; and default encryption key_id is not same as system default (1), a warning is issued and system default is used. SET GLOBAL innodb-default-encryption-key-id=10; CREATE TABLE t2 (pk INT PRIMARY KEY AUTO_INCREMENT, c VARCHAR(256)) ENGINE=INNODB ENCRYPTED=NO; Warnings: Warning 140 InnoDB: Ignored ENCRYPTION_KEY_ID 10 when encryption is disabled Currently set default encryption key_id does not effect tables that are created using specific encryption key_id e.g. create table t1(a int) encrypted=yes encryption_key_id=4; Instead specified key_id (in above case 4) is used. Tables using encryption but no specific encryption key_id e.g. create table t1(a int) encrypted=yes; will use currently set default encryption key_id for that session or if no key_id defined the set global encryption key_id or system default. Tables using default table options e.g create table t1(a int); will use currently set global encryption key_id when encryption threads does key rotation from unencrypted to encrypted state. Changes innodb-checksum-algorithm innodb-compressed-blob innodb-encryption-alter innodb-redo-badkey innodb-redo-nokeys These test require small changes as now we do not allow default key_id that is not found from encryption plugin and tables using no encryption produce warning when nondefault encryption key_id is used. fil0fil.cc::fil_crypt_start_encrypting_space() Use global default encryption key_id when creating encryption meta data. ha_innodb.cc::innodb_default_encryption_key_id_validate() New function to validate that used key_id is found from encryption plugin. ha_innodb.cc::thd_default_encryption_key_id() New accessessor function for default encryption key_id. ha_innodb.cc::innobase_init() Do not allow server startup using encryption key_id that is not found from encryption plugin. --- .../encryption/r/innodb-checksum-algorithm.result | 2 +- .../encryption/r/innodb-compressed-blob.result | 2 + .../encryption/r/innodb-encryption-alter.result | 31 +++++----- .../r/innodb_encryption_default_key.result | 39 +++++++++++++ .../encryption/t/innodb-checksum-algorithm.test | 6 +- .../encryption/t/innodb-encryption-alter.test | 9 +-- .../suite/encryption/t/innodb-redo-badkey.opt | 2 +- .../suite/encryption/t/innodb-redo-badkey.test | 2 +- .../suite/encryption/t/innodb-redo-nokeys.opt | 2 +- .../suite/encryption/t/innodb-redo-nokeys.test | 2 +- .../encryption/t/innodb_encryption_default_key.opt | 2 + .../t/innodb_encryption_default_key.test | 66 +++++++++++++++++++++ storage/innobase/fil/fil0crypt.cc | 5 +- storage/innobase/handler/ha_innodb.cc | 67 +++++++++++++++++++++- storage/innobase/include/ha_prototypes.h | 5 ++ storage/xtradb/fil/fil0crypt.cc | 5 +- storage/xtradb/handler/ha_innodb.cc | 67 +++++++++++++++++++++- storage/xtradb/include/ha_prototypes.h | 5 ++ 18 files changed, 285 insertions(+), 34 deletions(-) diff --git a/mysql-test/suite/encryption/r/innodb-checksum-algorithm.result b/mysql-test/suite/encryption/r/innodb-checksum-algorithm.result index a853f3869a9..b3deac98e3c 100644 --- a/mysql-test/suite/encryption/r/innodb-checksum-algorithm.result +++ b/mysql-test/suite/encryption/r/innodb-checksum-algorithm.result @@ -10,7 +10,7 @@ SET GLOBAL innodb_encrypt_tables = ON;
