The '@' symbol can not be used in the host name according to rfc952. The fix: added function check_host_name(LEX_STRING *str) which checks that all symbols in host name string are valid and host name length is not more than max host name length (just moved check_string_length() function from the parser into check_host_name()). mysql-test/r/create.result: test result mysql-test/t/create.test: test case sql/mysql_priv.h: added function check_host_name(LEX_STRING *str) sql/sql_parse.cc: added function check_host_name(LEX_STRING *str) which checks that all symbols in host name string are valid and host name length is not more than max host name length(HOSTNAME_LENGTH). sql/sql_yacc.yy: using newly added function check_host_name()

The problem: I_S views table does not check the presence of SHOW_VIEW_ACL|SELECT_ACL privileges for a view. It leads to discrepancy between SHOW CREATE VIEW and I_S.VIEWS. The fix: added appropriate check. mysql-test/r/information_schema_db.result: test result mysql-test/t/information_schema_db.test: test case sql/sql_show.cc: The problem: I_S views table does not check the presence of SHOW_VIEW_ACL|SELECT_ACL privileges for a view.

When analyzing the possible index use cases the server was re-using an internal structure. This is wrong, as this internal structure gets updated during the analysis. Fixed by making a copy of the internal structure for every place it needs to be used. Also stopped the generation of empty SEL_TREE structures that unnecessary complicate the analysis. mysql-test/r/index_merge.result: Bug#37943: test case mysql-test/t/index_merge.test: Bug#37943: test case sql/opt_range.cc: Bug#37943: - Make copy constructors for SEL_TREE and sub-structures and use them when OR-ing trees. - don't generate empty SEL_TREEs. Return NULL instead.

This patch contains fixes for two problems: 1. As originally reported, the server crashed on Mac OS X when trying to access an EXAMPLE table after the EXAMPLE plugin was installed. It turned out that the dynamically loaded EXAMPLE plugin called the function hash_earch() from a Mac OS X system library, instead of hash_earch() from MySQL's mysys library. Makefile.am in storage/example does not include libmysys. So the Mac OS X linker arranged the hash_search() function to be linked to the system library when the shared object is loaded. One possible solution would be to include libmysys into the linkage of dynamic plugins. But then we must have a libmysys.so, which must be used by the server too. This could have a minimal performance impact, but foremost the change seems to bee too risky at the current state of MySQL 5.1. The selected solution is to rename MySQL's hash_search() to my_hash_search() like it has been done before with hash_insert() and hash_reset(). Since this is the third time, we need to rename a hash_*() function, I did renamed all hash_*() functions to my_hash_*(). To avoid changing a zillion calls to these functions, and announcing this to hundreds of developers, I added defines that map the old names to the new names. This change is in hash.h and hash.c. 2. The other problem was improper implementation of the handlerton-to-plugin mapping. We use a fixed-size array to hold a plugin reference for each handlerton. On every install of a handler plugin, we allocated a new slot of the array. On uninstall we did not free it. After some uninstall/install cycles the array overflowed. We did not check for overflow. One fix is to check for overflow to stop the crashes. Another fix is to free the array slot at uninstall and search for a free slot at plugin install. This change is in handler.cc. include/hash.h: Bug#37958 - test main.plugin crash on Mac OS X when selecting from EXAMPLE engine. Renamed hash_*() functions to my_hash_*(). Added defines that map old names to new names. mysys/hash.c: Bug#37958 - test main.plugin crash on Mac OS X when selecting from EXAMPLE engine. Renamed hash_*() functions to my_hash_*(). sql/handler.cc: Bug#37958 - test main.plugin crash on Mac OS X when selecting from EXAMPLE engine. Protect against a failing ha_initialize_handlerton() in ha_finalize_handlerton(). Free hton2plugin slot on uninstall of a handler plugin. Reuse freed slost of the hton2plugin array. Protect against array overrun.

Server created "arc" directories inside database directories and maintained there useless copies of .frm files. Creation and renaming procedures of those copies as well as creation of "arc" directories has been discontinued. Removal procedure has been kept untouched to be able to cleanup existent database directories by the DROP DATABASE query. Also view renaming procedure has been updated to remove these directories. sql/parse_file.cc: Fixed bug #17823: 'arc' directories inside database directories. View/table creation and renaming procedures maintained backup copies of .frm files. Those copies are unused yet, so this feature was incomplete and unnecessary. 1. Unwanted code has been hidden by FRM_ARCHIVE ifdefs (the FRM_ARCHIVE macro is not defined). 2. Renaming procedure has been modified to remove obsolete "arc" directories. sql/parse_file.h: Fixed bug #17823: 'arc' directories inside database directories. The "thd" parameter has been added to the rename_in_schema_file() function. sql/sql_db.cc: Fixed bug #17823: 'arc' directories inside database directories. Scope of the mysql_rm_arc_files() function has been changed to global for use from the parse_file.cc file. sql/sql_view.cc: Fixed bug #17823: 'arc' directories inside database directories. Added the "thd" argument to rename_in_schema_file() calls.

The problem is that when statement-based replication was enabled, statements such as INSERT INTO .. SELECT FROM .. and CREATE TABLE .. SELECT FROM need to grab a read lock on the source table that does not permit concurrent inserts, which would in turn be denied if the source table is a log table because log tables can't be locked exclusively. The solution is to not take such a lock when the source table is a log table as it is unsafe to replicate log tables under statement based replication. Furthermore, the read lock that does not permits concurrent inserts is now only taken if statement-based replication is enabled and if the source table is not a log table. include/thr_lock.h: Introduce yet another lock type that my get upgraded depending on the binary log format. This is not a optimal solution but can be easily improved later. mysql-test/r/log_tables.result: Add test case result for Bug#34306 mysql-test/suite/binlog/r/binlog_stm_row.result: Add test case result for Bug#34306 mysql-test/suite/binlog/t/binlog_stm_row.test: Add test case for Bug#34306 mysql-test/t/log_tables.test: Add test case for Bug#34306 sql/lock.cc: Assert that TL_READ_DEFAULT is not a real lock type. sql/mysql_priv.h: Export new function. sql/mysqld.cc: Remove using_update_log. sql/sql_base.cc: Introduce function that returns the appropriate read lock type depending on how the statement is going to be replicated. It will only take a TL_READ_NO_INSERT log if the binary is enabled and the binary log format is statement-based and the table is not a log table. sql/sql_parse.cc: Remove using_update_log. sql/sql_update.cc: Use new function to choose read lock type. sql/sql_yacc.yy: The lock type is now decided at open_tables time. This old behavior was actually misleading as the binary log format can be dynamically switched and this would not change for statements that have already been parsed when the binary log format is changed (ie: prepared statements).
