Bug#16877045 5.6-CLUSTER-7.3 WIN32 SQL_YACC.CC BUILD PROBLEM
- Somewhat circular dependency caused by the configured files sql_builtin.cc being included as
part of the files to generate in sql/
- Move sql_builtin.cc out of GEN_SOURCES variable.
- Create new variable CONF_SOURCES to be used for configured files.
- the probably ultimate fix for dependencies on VS
- remove some GET_TARGET_PROPERTY(LOCATION ...), they are deprecated in
cmake 3.9
- simplify signing targets on Windows.
- remove INSTALL_DEBUG_TARGET, we do not mix binaries from different builds
in the same package
To export symbols from the mysqld.exe, use lib.exe with /DEF, rather than
pre-link step when building mysqld.exe.
This helps to avoid relinking all plugins, if mysqld.exe was recompiled
but the list of its exports has not changed.
Also removed unnecessary DEPENDS in some ADD_CUSTOM_COMMAND (gen_lex_token,
gen_lex_hash etc). They confuse VS generator which tends to
recreate headers and do unnecessary recompilations.
in default installation.
Added plugin-dir to the [client] section of the generated my.ini,
so that installed services (MSI or mysql_install_db.exe) would be able to
find plugin directory.
The changes are deliberately kept minimal
- some functions are made global instead of static (they will be used in
xtrabackup later on)
- functions got additional parameter, deliberately unused for now :
fil_load_single_tablespaces
srv_undo_tablespaces_init
- Global variables added, also unused for now :
srv_archive_recovery
srv_archive_recovery_limit_lsn
srv_apply_log_only
srv_backup_mode
srv_close_files
- To make xtrabackup link with sql.lib on Windows, added some missing
source files to sql.lib
- Fixed os_thread_ret_t to be DWORD on Windows
This task is to allow storage engines that can execute GROUP BY or
summary queries efficiently to intercept a full query or sub query from
MariaDB and deliver the result either to the client or to a temporary
table for further processing.
- Added code in sql_select.cc to intercept GROUP BY queries.
Creation of group_by_handler is done after all optimizations to allow
storage engine to benefit of an optimized WHERE clause and suggested
indexes to use.
- Added group by handler to sequence engine and a group_by test suite as
a way to test the new interface.
- Intercept EXPLAIN with a message "Storage engine handles GROUP BY"
libmysqld/CMakeLists.txt:
Added new group_by_handler files
sql/CMakeLists.txt:
Added new group_by_handler files
sql/group_by_handler.cc:
Implementation of group_by_handler functions
sql/group_by_handler.h:
Definition of group_by_handler class
sql/handler.h:
Added handlerton function to create a group_by_handler, if the storage
engine can intercept the query.
sql/item_cmpfunc.cc:
Allow one to evaluate item_equal any time.
sql/sql_select.cc:
Added code to intercept GROUP BY queries
- If all tables are from the same storage engine and the query is
using sum functions, call create_group_by() to check if the storage
engine can intercept the query.
- If yes:
- create a temporary table to hold a GROUP_BY row or result
- In do_select() intercept normal query execution by instead
calling the group_by_handler to get the result
- Intercept EXPLAIN
sql/sql_select.h:
Added handling of group_by_handler
Added caching of the original join tab (needed for cleanup after
group_by handler)
storage/sequence/mysql-test/sequence/group_by.result:
Test group_by_handler interface
storage/sequence/mysql-test/sequence/group_by.test:
Test group_by_handler interface
storage/sequence/sequence.cc:
Added simple group_by_engine for handling COUNT(*) and
SUM(primary_key). This was done as a test of the group_by_handler
interface
Item_func_hybrid_field_type did not return correct field_type(), cmp_type()
and result_type() in some cases, because cached_result_type and
cached_field_type were set in independent pieces of the code and
did not properly match to each other.
Fix:
- Removing Item_func_hybrid_result_type
- Deriving Item_func_hybrid_field_type directly from Item_func
- Introducing a new class Type_handler which guarantees that
field_type(), cmp_type() and result_type() are always properly synchronized
and using the new class in Item_func_hybrid_field_type.

Backport from mysql-5.6 to mysql-5.5
Merged lp:maria/maria-10.0-galera up to revision 3879.
Added a new functions to handler API to forcefully abort_transaction,
producing fake_trx_id, get_checkpoint and set_checkpoint for XA. These
were added for future possiblity to add more storage engines that
could use galera replication.
