MDEV-6610 Assertion `thd->is_error() || thd->killed' failed in mysql_execute_command on executing an SP with repeated CREATE TABLE .. SELECT the bug was introduced by CREATE OR REPLACE implementation. CREATE IF NOT EXISTS ... SELECT was returning an error status to the caller, while sending an ok packet to the user. SP code was not prepared for that and trusted that error status means an error.

The Item_string constructors called set_name() on the source string, which was wrong because in case of UCS2/UTF16/UTF32 the source value might be a not well formed string (e.g. have incomplete leftmost character). Now set_name() is called on str_value after its copied (with optionally left zero padding) from the source string. - MDEV-6694 Illegal mix of collation with a PS parameter Item_param::convert_str_value() did not set repertoire. Introducing a new structure MY_STRING_METADATA to collect character length and repertoire of a string in a single loop, to avoid two separate loops. Adding a new class Item_basic_value::Metadata as a convenience wrapper around MY_STRING_METADATA, to reuse the code between Item_string and Item_param.

and moving set_value() from Item_string to Item_string_for_in_vector, as set_value() updates the members incompletely (e.g. does not update max_length), so it was dangerous to have set_value() available in Item_string.

MDEV-6462: Slave replicating using GTID doesn't recover correctly when master crashes in the middle of transaction If the slave gets a reconnect in the middle of a GTID event group, normally it will re-fetch that event group, skipping the first part that was already queued for the SQL thread. However, if the master crashed while writing the event group, the group is incomplete. This patch detects this case and makes sure that the transaction is rolled back and nothing is skipped from any following event groups. Similarly, a network proxy might cause the reconnect to end up on a different master server. Detect this by noticing a different server_id, and similarly in this case roll back the partially received group.

Item_string::eq() and Item_param::eq() in string context behaved differently. Introducing a new class Item_basic_value to share the eq() code between literals (Item_int, Item_double, Item_string, Item_null) and Item_param.

MDEV-6666 Malformed result for CONCAT(utf8_column, binary_string) Item_static_string_func::safe_charset_converter() and Item_hex_string::safe_charset_converter() did not handle character sets with mbminlen>1 properly, as well as did not handle conversion from binary to multi-byte well. Introducing Item::const_charset_converter(), to reuse it in a number of Item_*::safe_charset_converter().

Analysis: When database is migrated from 5.5 or earlier and database needs crash recovery, there is possibility that SYS_DATAFILES system table does not exists, but crash recovery in function dict_check_tablespaces_and_store_max_id() assumes that SYS_DATAFILES exists. Fix: If SYS_DATAFILES does not exists, create it before we end up to function dict_check_tablespaces_and_store_max_id() on crash recovery.

After-review fixes. Mainly catching if the wait in wait_for_workers_idle() is aborted due to kill. In this case, we should return an error and not proceed to execute the format description event, as other threads might still be running for a bit until the error is caught in all threads.

Follow-up patch, fixing a possible deadlock issue. If the master crashes in the middle of an event group, there can be an active transaction in a worker thread when we encounter the following master restart format description event. In this case, we need to notify that worker thread to abort and roll back the partial event group. Otherwise a deadlock occurs: the worker thread waits for the commit that never arrives, and the SQL driver thread waits for the worker thread to complete its event group, which it never does.

When a view is merged, mark its select_lex as already optimized, otherwise its where clause (which doesn't have to be a valid Item after merging) might be accessed later. But don't do that for inserts (where a view cannot be simply merged, if one later needs to insert into it).

have been created by the last addition of new CONNECT features. The version previous to this one is a preliminary test version and should not be distributed. - Handle indexed UPDATE/DELETE. Previously this was just tested and an error message send when it could not be done. Now CONNECT can do it in all the cases. It is done by a MRR like tchnique by making a list of all update or delete to do, sort them, then execute them. modified: storage/connect/array.cpp storage/connect/array.h storage/connect/filamap.cpp storage/connect/filamap.h storage/connect/filamdbf.cpp storage/connect/filamfix.cpp storage/connect/filamfix.h storage/connect/filamtxt.cpp storage/connect/filamtxt.h storage/connect/filamvct.cpp storage/connect/filamvct.h storage/connect/filamzip.cpp storage/connect/filamzip.h storage/connect/global.h storage/connect/ha_connect.cc storage/connect/ha_connect.h - Differenciate Cardinality that returns a true or estimated table size and GetMaxSize that return a value equal or greater than the table row number. This fixes the errors of non matching opt files. modified: storage/connect/connect.cc storage/connect/tabdos.cpp storage/connect/tabdos.h storage/connect/tabfix.cpp storage/connect/table.cpp storage/connect/tabmac.h storage/connect/tabmysql.cpp storage/connect/tabmysql.h storage/connect/tabodbc.cpp storage/connect/tabodbc.h storage/connect/tabpivot.h storage/connect/tabtbl.cpp storage/connect/tabtbl.h storage/connect/tabutil.cpp storage/connect/tabutil.h storage/connect/tabwmi.h storage/connect/xtable.h - Fix some errors and issues when making index and opt files. Erase opt and index files for void tables. Fix wrong calculation of Block and Last in MakeBlockValues. Invalidate indexes before making opt file. Fully handle blocked variable tables. Make opt file for blocked variable tables even when they have no optimised colums. modified: storage/connect/tabdos.cpp storage/connect/xindex.h - Fix some errors making index Return an error when the allocation is too small (should not really occur now that GetMaxSize is sure) Don't use XXROW index for DBF tables because of soft deleted lines. modified: storage/connect/xindex.cpp - Typo modified: storage/connect/macutil.cpp storage/connect/tabdos.h storage/connect/tabsys.cpp storage/connect/tabsys.h
