Implements the DISTINCT modifier for ST_Collect Author: StefanoPetrilli <stefanop_1999@hotmail.it>
-
Stefano Petrilli authored
The GIS function ST_Collect takes as input multiple geometries and returns the aggregation of the distinct geometry arguments. The resulting value type is choosen using the following policy: - If all arguments are Point values, the result is a MultiPoint value. - If all arguments are LineString values, the result is a MultiLineString value. - If all arguments are Polygon values, the result is a MultiPolygon value. - Otherwise, the result is a GeometryCollection value. If there are multiple geometry arguments and those arguments are in the same SRS, the return value is in that SRS. If those arguments are not in the same SRS, an ER_GIS_DIFFERENT_SRIDS_AGGREGATION error occurs.

The GIS function ST_Validate takes ad input a geometry and verifies that - is compliant with the Well-Known Binary (WKB) format and Spatial Reference System Identifier (SRID) syntax. - is geometrically valid. If the input is valid return it, else it returns NULL. The use case of this function is to filter out invalid geometry data. Author: StefanoPetrilli <stefanop_1999@hotmail.it> Co-authored-by:

The GIS function ST_Simplify takes ad input a geometry and a double. It applies the Ramer-Douglas-Peucker algorithm on the geometry and returns the resulting geometry. The tests have been cherry-picked from the MySQL implementation of this function to grant compatibility among the two implementations. Co-authored-by:

The GIS function ST_PointFromGeoHash takes in input a geohash and returns a point where the x is the longitude and the y is the latitude. The latitude is returned as a numeric value in the interval [180, -180]. The longitude is returned as a numeric value in the interval [90, -90]. If the argument is NULL, the return value is NULL. If the argument is invalid, an ER_GIS_INVALID_DATA is thrown. Author: StefanoPetrilli <stefanop_1999@hotmail.it> Co-authored-by:

The function returns the geohash corresponding to the input values. The GIS function ST_GeoHash takes as input: (longitude, latitude, max_length), OR (point, max_length) The longitue parameter is a numeric value in the interval [180, -180], the latitude is a numeric value in the interval [90, -90]. In the case of point, the x coordinate is treated as the latitude and the y coordinate is treated as the latitude. Even in the case of a point, the same constraints apply. The max_length parameter is the upper limit on the resulting string size and cannot exceed 100. Author: StefanoPetrilli <stefanop_1999@hotmail.it> Co-authored-by:

for large transaction Description =========== When a transaction commits, it copies the binlog events from binlog cache to binlog file. Very large transactions (eg. gigabytes) can stall other transactions for a long time because the data is copied while holding LOCK_log, which blocks other commits from binlogging. The solution in this patch is to rename the binlog cache file to a binlog file instead of copy, if the commiting transaction has large binlog cache. Rename is a very fast operation, it doesn't block other transactions a long time. Design ====== * binlog_large_commit_threshold type: ulonglong scope: global dynamic: yes default: 128MB Only the binlog cache temporary files large than 128MB are renamed to binlog file. * #binlog_cache_files directory To support rename, all binlog cache temporary files are managed as normal files now. `#binlog_cache_files` directory is in the same directory with binlog files. It is created at server startup if it doesn't exist. Otherwise, all files in the directory is deleted at startup. The temporary files are named with ML_ prefix and the memorary address of the binlog_cache_data object which guarantees it is unique. * Reserve space To supprot rename feature, It must reserve enough space at the begin of the binlog cache file. The space is required for Format description, Gtid list, checkpoint and Gtid events when renaming it to a binlog file. Since binlog_cache_data's cache_log is directly accessed by binlog log, online alter and wsrep. It is not easy to update all the code. Thus binlog cache will not reserve space if it is not session binlog cache or wsrep session is enabled. - m_file_reserved_bytes Stores the bytes reserved at the begin of the cache file. It is initialized in write_prepare() and cleared by reset(). The reserved file header is hide to callers. Thus there is no change for callers. E.g. - get_byte_position() still get the length of binlog data written to the cache, but not the file length. - truncate(0) will truncate the file to m_file_reserved_bytes but not 0. - write_prepare() write_prepare() is called everytime when anything is being written into the cache. It will call init_file_reserved_bytes() to create the cache file (if it doesn't exist) and reserve suitable space if the data written exceeds buffer's size. * Binlog_commit_by_rotate It is used to encapsulate the code for remaing a binlog cache tempoary file to binlog file. - should_commit_by_rotate() it is called by write_transaction_to_binlog_events() to check if a binlog cache should be rename to a binlog file. - commit() That is the entry to rename a binlog cache and commit the transaction. Both rename and commit are protected by LOCK_log, Thus not other transactions can write anything into the renamed binlog before it. Rename happens in a rotation. After the new binlog file is generated, replace_binlog_file() is called to: - copy data from the new binlog file to its binlog cache file. - write gtid event. - rename the binlog cache file to binlog file. After that the rotation will continue to succeed. Then the transaction is committed in a seperated group itself. Its cache file will be detached and cache log will be reset before calling trx_group_commit_with_engines(). Thus only Xid event be written. -

Extend derived table syntax to support column name assignment. (subquery expression) [as|=] ident [comma separated column name list]. Prior to this patch, the optional comma separated column name list is not supported. Processing within the unit of the subquery expression will use original column names, outside the unit will use the new names. For example, in the query select a1, a2 from (select c1, c2, c3 from t1 where c2 > 0) as dt (a1, a2, a3) where a2 > 10; we see the second column of the derived table dt being used both within, (where c2 > 0), and outside, (where a2 > 10), the specification. Both conditions apply to t1.c2. When multiple unit preparations are required, such as when being used within a prepared statement or procedure, original column names are needed for correct resolution. Original names are reset within mysql_derived_reinit(). Item_holder items, used for result tables in both TVC and union preparations are renamed before use within st_select_lex_unit::prepare(). During wildcard expansion, if column names are present, items names are set directly after creation. Reviewed by Igor Babaev (igor@mariadb.com)

One change is that if the port is not supplied or out of bound, the old behaviour is to print 3306. The new behaviour is to not print it (if not supplied) or the out of bound value.

The existing syntax for CREATE SERVER CREATE [OR REPLACE] SERVER [IF NOT EXISTS] server_name FOREIGN DATA WRAPPER wrapper_name OPTIONS (option [, option] ...) option: { HOST character-literal | DATABASE character-literal | USER character-literal | PASSWORD character-literal | SOCKET character-literal | OWNER character-literal | PORT numeric-literal } With this change we have: option: { HOST character-literal | DATABASE character-literal | USER character-literal | PASSWORD character-literal | SOCKET character-literal | OWNER character-literal | PORT numeric-literal | PORT quoted-numerical-literal | identifier character-literal} We store these options as a JSON field in the mysql.servers system table. We retain the restriction that PORT needs to be a number, but also allow it to be a quoted number, so that SHOW CREATE SERVER can be used for dumping. Without an accompanied implementation of SHOW CREATE SERVER, some mysqldump tests will fail. Therefore this commit should be immediately followed by the one implementating SHOW CREATE SERVER, with testing covering both. -

The limit of socket length on unix according to libc is 108, see sockaddr_un::sun_path, but in the table it is a string of max length 64, which results in truncation of socket and failure to connect by plugins using servers such as spider.

Update `SESSION_USER()` behaviour to be comparable with `CURRENT_USER()`. `SESSION_USER()` will return the user and host columns from `mysql.user` used to authenticate the user when the session was created. Historically `SESSION_USER()` was an alias of `USER()` function. The main difference with `USER()` behaviour after this changes is that `SESSION_USER()` now returns the host column from `mysql.user` instead of the client host or ip. NOTE: `SESSION_USER_IS_USER` old mode is added to make the change backward compatible.

to explicit row_start/row_end columns In case of adding both system fields of same type (length, unsigned flag) as old implicit system fields do the rename of implicit system fields to the ones specified in ALTER, remove SYSTEM_INVISIBLE flag in that case. Correct PERIOD clause must be specified in ALTER as well. MDEV-34904 Inplace alter for implicit to explicit versioning is broken Whether ALTER goes inplace and how it goes inplace depends on handler_flags which goes from alter_info->flags by this logic: ha_alter_info->handler_flags|= (alter_info->flags & ~flags_to_remove); ALTER_VERS_EXPLICIT was not in flags_to_remove and its value (1ULL << 35) clashed with ALTER_ADD_NON_UNIQUE_NON_PRIM_INDEX. ALTER_VERS_EXPLICIT must not affect inplace, it is SQL-only so we remove it from handler_flags.

During a query execution some sorting and grouping operations on strings may be involved. System variable max_sort_length defines the maximum number of bytes to use when comparing strings during sorting/grouping. Thus, the comparable parts of strings may be less than their actual size, so the results of the query may be not sorted/grouped properly. To indicate that some comparisons were done on a truncated lengths, a new warning has been introduced with this commit.

Single-table UPDATE/DELETE didn't provide outer_lookup_keys value for subqueries. This didn't allow to make a meaningful choice between IN->EXISTS and Materialization strategies for subqueries. Fix this: * Make UPDATE/DELETE save Sql_cmd_dml::scanned_rows, * Then, subquery's JOIN::choose_subquery_plan() can fetch it from there for outer_lookup_keys Details: UPDATE/DELETE now calls select_lex->optimize_unflattened_subqueries() twice, like SELECT does (first call optimize_constant_subquries() in JOIN::optimize_inner(), then call optimize_unflattened_subqueries() in JOIN::optimize_stage2()): 1. Call with const_only=true before any optimizations. This allows range optimizer and others to use the values of cheap const subqueries. 2. Call it with const_only=false after range optimizer, partition pruning, etc. outer_lookup_keys value is provided, so it's possible to pick a good subquery strategy. Note: PROTECT_STATEMENT_MEMROOT requires that first SP execution performs subquery optimization for all subqueries, even for degenerate query plans like "Impossible WHERE". Due to that, we ensure that the call to optimize_unflattened_subqueries (with const_only=false) even for degenerate query plans still happens, as was the case before this change.

Changing the return type of the following functions: - CURRENT_TIMESTAMP, CURRENT_TIMESTAMP(), NOW() - SYSDATE() - FROM_UNIXTIME() from DATETIME to TIMESTAMP. Note, the old function NOW() returning DATETIME is still available as LOCALTIMESTAMP or LOCALTIMESTAMP(), e.g.: SELECT LOCALTIMESTAMP, -- DATETIME CURRENT_TIMESTAMP; -- TIMESTAMP The change in the functions return data type fixes some problems that occurred near a DST change: - Problem #1 INSERT INTO t1 (timestamp_field) VALUES (CURRENT_TIMESTAMP); INSERT INTO t1 (timestamp_field) VALUES (COALESCE(CURRENT_TIMESTAMP)); could result into two different values inserted. - Problem #2 INSERT INTO t1 (timestamp_field) VALUES (FROM_UNIXTIME(1288477526)); INSERT INTO t1 (timestamp_field) VALUES (FROM_UNIXTIME(1288477526+3600)); could result into two equal TIMESTAMP values near a DST change. Additional changes: - FROM_UNIXTIME(0) now returns SQL NULL instead of '1970-01-01 00:00:00' (assuming time_zone='+00:00') - UNIX_TIMESTAMP('1970-01-01 00:00:00') now returns SQL NULL instead of 0 (assuming time_zone='+00:00' These additional changes are needed for consistency with TIMESTAMP fields, which cannot store '1970-01-01 00:00:00 +00:00'. -

Adding support for the ROW data type in the stored function RETURNS clause: - explicit ROW(..members...) for both sql_mode=DEFAULT and sql_mode=ORACLE CREATE FUNCTION f1() RETURNS ROW(a INT, b VARCHAR(32)) ... - anchored "ROW TYPE OF [db1.]table1" declarations for sql_mode=DEFAULT CREATE FUNCTION f1() RETURNS ROW TYPE OF test.t1 ... - anchored "[db1.]table1%ROWTYPE" declarations for sql_mode=ORACLE CREATE FUNCTION f1() RETURN test.t1%ROWTYPE ... Adding support for anchored scalar data types in RETURNS clause: - "TYPE OF [db1.]table1.column1" for sql_mode=DEFAULT CREATE FUNCTION f1() RETURNS TYPE OF test.t1.column1; - "[db1.]table1.column1" for sql_mode=ORACLE CREATE FUNCTION f1() RETURN test.t1.column1%TYPE; Details: - Adding a new sql_mode_t parameter to sp_head::create() sp_head::sp_head() sp_package::create() sp_package::sp_package() to guarantee early initialization of sp_head::m_sql_mode. Before this change, this member was not initialized at all during CREATE FUNCTION/PROCEDURE/PACKAGE statements, and was not used. Now it needs to be initialized to write properly the mysql.proc.returns column, according to the create time sql_mode. - Code refactoring to make the things simpler and functions smaller: * Adding a new method Field_row::row_create_fields(THD *thd, List<Spvar_definition> *list) to make a Virtual_tmp_table with Fields for ROW members from an explicit definition. * Adding a new method Field_row::row_create_fields(THD *thd, const Spvar_definition &def) to make a Virtual_tmp_table with Fields for ROW members from an explicit or a table anchored definition. * Adding a new method Item_args::add_array_of_item_field(THD *thd, const Virtual_tmp_table &vtable) to create and array of Item_field corresponding to all Field instances in a Virtual_tmp_table * Removing Item_field_row::row_create_items(). It was decomposed into the new methods described above. * Moving the code from the loop body in sp_rcontext::init_var_items() into a separate method Spvar_definition::make_item_field_row(), to make the code clearer (smaller functions). make_item_field_row() itself uses the new methods described above. - Changing the data type of sp_head::m_return_field_def from Column_definition to Spvar_definition. So now it supports not only SQL column field types, but also explicit ROW and anchored ROW data types, as well as anchored column types. - Adding a new Column_definition parameter to sp_head::create_result_field(). Before this patch, create_result_field() took the definition only from m_return_field_def. Now it's also called with a local Column_definition variable which contains the explicit definition resolved from an anchored defition. - Modifying sql_yacc.yy to support the new grammar. Adding new helper methods: * sf_return_fill_definition_row() * sf_return_fill_definition_rowtype_of() * sf_return_fill_definition_type_of() - Fixing tests in: * Virtual_tmp_table::setup_field_pointers() in sql_select.cc * Send_field::normalize() in field.h * store_column_type() to prevent calling Type_handler_row::field_type(), which is implemented a DBUG_ASSERT(0). Before this patch the affected methods and functions were called only for scalar data types. Now ROW is also possible. - Adding a new virtual method Field::cols() - Overriding methods: Item_func_sp::cols() Item_func_sp::element_index() Item_func_sp::check_cols() Item_func_sp::bring_value() to support the ROW data type. - Extending the rule sp_return_type to support * explicit ROW and anchored ROW data types * anchored scalar data types - Overriding Field_row::sql_type() to print the data type of an explicit ROW. -
