| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. Removed TIMESTAMP/TRANSACTION unit auto-detection in favor of default TIMESTAMP. Reasons: 1.1. rare practical use and doubtful advantage of such auto-detection; 1.2. it conflicts with MDEV-16226 (TRX_ID-based versioned tables performance improvement). Needless check_unit membership removed. 2. SQL: versioning type handling refactoring Vers_type_handler hierarchy stores versioning properties of type. virtual Type_handler::vers() accesses specialization of Vers_type_handler for specific type. virtual Vers_type_handler::kind() returns versioning kind (timestamp/trx_id). Removed Type_handler::Vers_history_point_check_unit() in favor of Type_handler::vers(). Renames: require_timestamp() -> require_timestamp_error() require_trx_id() -> require_trx_id_error() EDIT by Alexander Barkov (@abarkov): check_sys_fields() moved to Vers_type_handler::check_sys_fields()

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Hiding the definitions inside Type_handler_xxx::name(). This is needed to avoid exporting members with MYSQL_PLUGIN_IMPORT, which would be needed to compile data type plugins on Windows.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introducing methods instead: const Name version_mysql56() const; const Name version_mariadb53() const; This is needed to avoid exporting members with MYSQL_PLUGIN_IMPORT, which would be needed to compile data type plugins on Windows.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit e86010f909fb6b8c4ffd9d6df92991ac079e67e7. Reverting on Monty's request, as this change makes merging things from 10.5 to 10.2 much harder.

| | * | MDEV-17551 assert or crashed table when using blobsMonty2019-06-271-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The bug was that when long item-strings was converted to VARCHAR, type_handler::string_type_handler() didn't take into account max VARCHAR length. The resulting Aria temporary table was created with a VARCHAR field of length 1 when it should have been 65537. This caused MariaDB to send impossible records to ma_write() and Aria reported eventually the table as crashed. Fixed by updating Type_handler::string_type_handler() to not create too long VARCHAR fields. To make things extra safe, I also added checks in when writing dynamic Aria records to ensure we find the wrong record during write instead of during read.

| * | | NFC: refactor Field::is_equal() and related stuffEugene Kosov2019-06-221-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make Field::is_equal() const and return bool as it's a naturally fitting type for it. Also it's agrument was narrowed to Column_definition. InnoDB can change type of some columns by itself. InnoDB-specific code used to reside in Field_xxx:is_equal() methods. Now engine-specific stuff was moved to a virtual methods of handler::can_convert{string,varstring,blob,geom}. These methods are called by Field::can_be_converted_by_engine() which is a double dispatch pattern. Some InnoDB-specific code still resides in compare_keys_but_name(). It should be moved from here someday to handler::compare_key_parts(...) or similar. IS_EQUAL_WITH_REINTERPRET_COMPATIBLE_CHARSET IS_EQUAL_WITH_REINTERPRET_COMPATIBLE_CHARSET_BUT_COLLATE: both was removed IS_EQUAL_NO, IS_EQUAL_YES are not needed now and should be removed along with deprecated handler::check_if_incompatible_data(). HA_EXTENDED_TYPES_CONVERSION: was removed as such logic is not needed now by server code. ALTER_COLUMN_EQUAL_PACK_LENGTH: was renamed to a more generic ALTER_COLUMN_TYPE_CHANGE_BY_ENGINE
| * | | MDEV-17301 Change of COLLATE unnecessarily requires ALGORITHM=COPYEugene Kosov2019-06-221-12/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch is about two cases: 1) On some collate changes it's possible to rebuild only secondary indexes 2) For non-indexed columns collate can be changed INSTANTly Implemented mostly in Field_{string,varstring,blob}::is_equal(). Make this method return how exactly collationa differs. This information is later used by fill_alter_inplace_info() to pass correct info to engine.

Cleanup: Adding a helper method Field_longstr::csinfo_change_allows_instant_alter(), to remove some duplicate code in field.cc. 2. Cleanup: removing Type_handler::Charsets_are_compatible() and static function charsets_are_compatible() and introducing new methods in the recently added class Charset instead: - encoding_allows_reinterpret_as() - encoding_and_order_allow_reinterpret_as() 3. Bug fix: Removing the code that allowed instant conversion for ascii-to->8bit and ucs2-to->utf16. This actually fixes MDEV-19284 and MDEV-19285. 4. Bug fix: Adding a helper method Charset::collation_specific_name(). The old corresponding code in Type_handler::Charsets_are_compatible() was not safe against (badly named) user-defined collations whose character set name can be longer than collation name.
