Alexander Barkov	5352e9687a	MDEV-17363 - Compressed columns cannot be restored from dump In collaboration with Sergey Vojtovich <svoj@mariadb.org> The COMPRESSED clause is now a part of the data type and goes immediately after the data type and length, but before the CHARACTER SET clause, and before column attributes such as DEFAULT, COLLATE, ON UPDATE, SYSTEM VERSIONING, engine specific column attributes. In the old reduction, the COMPRESSED clause was a column attribute. New syntax: <varchar or text data type> <length> <compression> <character set> <column attributes> <varbinary or blob data type> <length> <compression> <column attributes> New syntax examples: VARCHAR(1000) COMPRESSED CHARACTER SET latin1 DEFAULT '' BLOB COMPRESSED DEFAULT '' Deprecate syntax examples: VARCHAR(1000) CHARACTER SET latin1 COMPRESSED DEFAULT '' TEXT CHARACTER SET latin1 DEFAULT '' COMPRESSED VARBINARY(1000) DEFAULT '' COMPRESSED As a side effect: - COMPRESSED is not valid as an SP label name in SQL/PSM routines any more (but it's still valid as an SP label name in sql_mode=ORACLE) - COMPRESSED is now allowed in combination with GENERATED ALWAYS AS: TEXT COMPRESSED GENERATED ALWAYS AS REPEAT('a',1000)	6 years ago

Igor Babaev	09aa5d3f69	MDEV-17894 Assertion `(thd->lex)->current_select' failed in MYSQLparse(), query with VALUES() A table value constructor can be used in all contexts where a select can be used. In particular an ORDER BY clause or a LIMIT clause or both of them can be attached to a table value constructor to produce a new query. Unfortunately execution of such queries was not supported. This patch fixes the problem.	7 years ago

Igor Babaev	d2013e7328	MDEV-18982 Partition pruning with column list causes syntax error in 10.4 A syntax error was reported for any INSERT statement with explicit partition selection it if i used a column list. Fixed by saving the parsing place before parsing the clause for explicit partition selection and restoring it when the clause has been parsed.	7 years ago
Sergey Vojtovich	3568427d11	MDEV-18450 Slaves wait shutdown The patches features an optional shutdown behavior to hold on until after all connected slaves have been sent the last binlogged event. The connected slave is one whose START SLAVE has been acknowledged and that was not stopped since that though it could be technically reconnecting in background. The solution therefore disallows killing the dump thread until is has found EOF of the latest binlog file. It is up to the shutdown requester (DBA) to set up a sufficiently large shutdown timeout value for shudown to wait patiently until lagging behind slaves have been synchronized. On the other hand if a specific slave needs exclusion from synchronization the DBA would have to stop it manually which would terminate its dump thread. `mysqladmin shutdown' is extended with a `--wait_for_all_slaves' option which translates to `SHUTDOW WAIT FOR ALL SLAVES' sql query to enable the feature on the client side. The patch also performs a small refactoring of the server shutdown around close_connections() to introduce kill thread phases which are two as of current.	7 years ago
Alexander Barkov	5f34513c2a	MDEV-18813 PROCEDURE and anonymous blocks silently ignore FETCH GROUP NEXT ROW Part#2 (final): rewritting the code to pass the correct enum_sp_aggregate_type to the sp_head constructor, so sp_head never changes its aggregation type later on. The grammar has been simplified and defragmented. This allowed to check aggregate specific instructions right after a routine body has been scanned, by calling new LEX methods: sp_body_finalize_{procedure\|function\|trigger\|event}() Moving some C++ code from *.yy to a few new helper methods in LEX.	7 years ago

Sergei Golubchik	1e6210161d	MDEV-7597 Expiration of user passwords post-merge changes: * handle password expiration on old tables like everything else - make changes in memory, even if they cannot be done on disk * merge "debug" tests with non-debug tests, they don't use dbug anyway * only run rpl password expiration in MIXED mode, it doesn't replicate anything, so no need to repeat it thrice * restore update_user_table_password() prototype, it should not change ACL_USER, this is done in acl_user_update() * don't parse json twice in get_password_lifetime and get_password_expired * remove LEX_USER::is_changing_password, see if there was any auth instead * avoid overflow in expiration calculations * don't initialize Account_options in the constructor, it's bzero-ed later * don't create ulong sysvars - they're not portable, prefer uint or ulonglong * misc simplifications	7 years ago
Robert Bindar	90ad4dbd17	MDEV-7597 Expiration of user passwords This patch adds support for expiring user passwords. The following statements are extended: CREATE USER user@localhost PASSWORD EXPIRE [option] ALTER USER user@localhost PASSWORD EXPIRE [option] If no option is specified, the password is expired with immediate effect. If option is DEFAULT, global policy applies according to the default_password_lifetime system var (if 0, password never expires, if N, password expires every N days). If option is NEVER, the password never expires and if option is INTERVAL N DAY, the password expires every N days. The feature also supports the disconnect_on_expired_password system var and the --connect-expired-password client option. Closes #1166	7 years ago

Alexander Barkov	62c0ac2da6	A cleanup for MDEV-13916 Enforce check constraint on JSON type 1. Renaming Type_handler_json to Type_handler_json_longtext There will be other JSON handlers soon, e.g. Type_handler_json_varchar. 2. Making the code more symmetric for data types: - Adding a new virtual method Type_handler::Column_definition_validate_check_constraint() - Moving JSON-specific code from sql_yacc.yy to Type_handler_json_longtext::Column_definition_validate_check_constraint() 3. Adding new files sql_type_json.cc and sql_type_json.h and moving Type_handler+JSON related code into these files.	7 years ago
Marko Mäkelä	ea0be9e2d6	MDEV-15564 Avoid table rebuild in ALTER TABLE on collation or charset changes Allow ALGORITHM=INSTANT (or avoid touching any data) when changing the collation, or in some cases, the character set, of a non-indexed CHAR or VARCHAR column. There is no penalty for subsequent DDL or DML operations, and compatibility with older MariaDB versions will be unaffected. Character sets may be changed when the old encoding is compatible with the new one. For example, changing from ASCII to anything ASCII-based, or from 3-byte to 4-byte UTF-8 can sometimes be performed instantly. This is joint work with Eugene Kosov. The test cases as well as ALTER_CONVERT_TO, charsets_are_compatible(), Type_handler::Charsets_are_compatible() are his work. The Field_str::is_equal(), Field_varstring::is_equal() and the InnoDB changes were mostly rewritten by me due to conflicts with MDEV-15563. Limitations: Changes of indexed columns will still require ALGORITHM=COPY. We should allow ALGORITHM=NOCOPY and allow the indexes to be rebuilt inside the storage engine, without copying the entire table. Instant column size changes (in bytes) are not supported by all storage engines. Instant CHAR column changes are only allowed for InnoDB ROW_FORMAT=REDUNDANT. We could allow this for InnoDB when the CHAR internally uses a variable-length encoding, say, when converting from 3-byte UTF-8 to 4-byte UTF-8. Instant VARCHAR column changes are allowed for InnoDB ROW_FORMAT=REDUNDANT, and for others only if the size in bytes does not change from 128..255 bytes to more than 256 bytes. Inside InnoDB, this slightly changes the way how MDEV-15563 works and fixes the result of the innodb.instant_alter_extend test. We change the way how ALTER_COLUMN_EQUAL_PACK_LENGTH_EXT is handled. All column extension, type changes and renaming now go through a common route, except when ctx->is_instant() is in effect, for example, instant ADD or DROP COLUMN has been initiated. Only in that case we will go through innobase_instant_try() and rewrite all column metadata. get_type(field, prtype, mtype, len): Convert a SQL data type into InnoDB column metadata. innobase_rename_column_try(): Remove the update of SYS_COLUMNS. innobase_rename_or_enlarge_column_try(): New function, replacing part of innobase_rename_column_try() and all of innobase_enlarge_column_try(). Also changes column types. innobase_rename_or_enlarge_columns_cache(): Also change the column type.	7 years ago
Sergei Golubchik	e5701d8363	cleanup: Account_options move account options from LEX to Account_options structure namely, mqh and ssl_* Also, use LEX_CSTRING for ssl_/x509_ strings and move setting of ACL_USER::account_locked where it belongs	7 years ago
Robert Bindar	6c8ce999f8	MDEV-13095 Implement User Account locking Add server support for user account locking. This patch extends the ALTER/CREATE USER statements for denying a user's subsequent login attempts: ALTER USER user [, user2] ACCOUNT [LOCK \| UNLOCK] CREATE USER user [, user2] ACCOUNT [LOCK \| UNLOCK] The SHOW CREATE USER statement was updated to display the locking state of an user. Closes #1006	7 years ago
Monty	0f48949439	MDEV-13916 Enforce check constraint on JSON type When creating a field of type JSON, it will be automatically converted to TEXT with CHECK (json_valid(`a`)), if there wasn't any previous check for the column. Additional things: - Added two bug fixes that was found while testing JSON. These bug fixes has also been pushed to 10.3 (with a test case), but as they where minimal and needed to get this task done and tested, the fixes are repeated here. - CREATE TABLE ... SELECT drops constraints for columns that are both in the create and select part. - If one has both a default expression and check constraint for a column, one can get the error "Expression for field `a` is refering to uninitialized field `a`. - Removed some duplicate MYSQL_PLUGIN_IMPORT symbols	7 years ago
Sergei Golubchik	5b15cc613e	MDEV-11340 Allow multiple alternative authentication methods for the same user introduce the syntax ... IDENTIFIED { WITH \| VIA } plugin [ { USING \| AS } auth ] [ OR plugin [ { USING \| AS } auth ] [ OR ... ]] Server will try auth plugins in the specified order until the first success. No protocol changes, server uses the existing "switch plugin" packet. The auth chain is stored in json as "auth_or":[{"plugin":"xxx","authentication_string":"yyy"}, {}, {"plugin":"foo","authentication_string":"bar"}, ...], "plugin":"aaa", "authentication_string":"bbb" Note: * "auth_or" implies that there might be "auth_and" someday; * one entry in the array is an empty object, meaning to take plugin/auth from the main json object. This preserves compatibility with the existing mysql.global_priv table and with the mysql.user view. This entry is preferrably a mysql_native_password plugin for a non-empty mysql.user.password column. SET PASSWORD is supported and changes the password for the first plugin in the chain that has a notion of a "password"	7 years ago

Sergey Vojtovich	8cf7e3459d	Moved early check for table existance to mysql_execute_command() MDEV-17772 - 3 way lock : ALTER, MDL, BACKUP STAGE BLOCK_DDL While waiting for a (potentially long) RO transaction or SELECT, DDL and LOCK TABLES ... WRITE hold protection against FTWRL and BACKUP STAGE. This effectively makes FTWRL/BACKUP STAGE indirectly wait for this RO transaction or SELECT to finish. Which is not great, as otherwise we could do something useful meanwhile. With this patch BACKUP lock is attempted to be acquired after TABLE/SCHEMA locks. If this attempt fails, TABLE/SCHEMA locks gets released and we start waiting for BACKUP lock. When wait finishes, BACKUP lock is released (to avoid deadlocks) and we attempt to acquire all locks once again. Other changes: - Take MDL lock before testing if table exists as part of CREATE TABLE ... IF EXISTS. This change was an effect of changes in lock_table_name and removes an inconsistency where one could get different error messages from CREATE TABLE .. IF EXISTS depending on active mdl locks. One effect of this change is that we don't binary log CREATE TABLE IF EXISTS if the table exists. This was done because old code was sometimes behaving inconsistenly (it was logged some time and not other times) and sending the query to the slave could make the slave even more inconsistent as there is not guarantee that the new table will have the same definition as the old table on the master.	7 years ago
Monty	c53aab974b	Added syntax and implementation for BACKUP STAGE's Part of MDEV-5336 Implement LOCK FOR BACKUP - Changed check of Global_only_lock to also include BACKUP lock. - We store latest MDL_BACKUP_DDL lock in thd->mdl_backup_ticket to be able to downgrade lock during copy_data_between_tables()	7 years ago
