Rev	Summary	Authors	Date
2778	Merge from 6.0 Merge from 6.0	Alexander Nozdrin	15 years ago
2777	Fix for bug #44738 "fill_schema_table_from_frm() opens table... Fix for bug #44738 "fill_schema_table_from_frm() opens tables without lowercasing table name". In lower_case_table_names > 0 mode some queries to I_S left entries with incorrect key in table definition cache. This wasted memory and in combination with similar problem in CREATE TABLE (which also has peeked into table definition cache using non-normalized key) led to to spurious ER_TABLE_EXISTS_ERROR errors when one tried to create a table with the same name as a previously existing but dropped table (assuming that table name contained characters in upper case). This problem occured due to fact that fill_schema_table_from_frm() was not properly normalizing (lowercasing) database and table names which it used for lookups in table definition cache. This fix adds proper normalization to this function. It also solves similar problem in CREATE TABLE's code by ensuring that it uses properly normalized version of table name when it peeks into table definition cache instead of non-normalized one.

2775	Bug #21793 Missing CF_CHANGES_DATA and CF_STATUS_COMMAND for... Bug #21793 Missing CF_CHANGES_DATA and CF_STATUS_COMMAND for handful of commands CF_CHANGES_DATA and CF_STATUS_COMMAND flags added to the commands mentioned in the bug description. With the following two exceptions: 1) 4 commands do not exist: SQLCOM_RENAME_DB SQLCOM_LOAD_MASTER_DATA SQLCOM_LOAD_MASTER_TABLE SQLCOM_SHOW_COLUMN_TYPES 2) All SQLCOM_SHOW_* commands already had CF_STATUS_COMMAND, leaving only SQLCOM_BINLOG_BASE64_EVENT. Further, check_prepared_statement() in sql_prepare.cc has been simplified by taking advantage of the CF_STATUS_COMMAND flag. Note that no test case has been added.	Jon Olav Hauglid	15 years ago

2772	Bug #31293 create logfile group/tablespace returns OK with w... Bug #31293 create logfile group/tablespace returns OK with warning when engine=myisam Bug title slightly misleading. The problem was that syntax errors (1064) were mistakenly generated for the following statements: CREATE TABLESPACE ALTER TABLESPACE DROP TABLESPACE CREATE LOGFILE GROUP ALTER LOGFILE GROUP DROP LOGFILE GROUP These statments used without any extra clauses gave syntax errors. Adding one or more clauses would remove the syntax error, even if those clauses are all defined as optional. The fix changes the grammar to accept statements without extra clauses so that the above statments give the proper error message used with engine=myisam: ERROR 1478 (HY000): Table storage engine 'MyISAM' does not support the create option 'TABLESPACE or LOGFILE GROUP' Note that the ENGINE clause was optional before this fix even if this does not match the current version of the reference manual where it is marked as required. The manual should therefore be updated marking the ENGINE clause as optional for all statements listed above. Parser.test appended with a test of various statements that should give error 1478 ER_ILLEGAL_HA_CREATE_OPTION, but before gave syntax error.	Jon Olav Hauglid	15 years ago
2771	Follow-up for fix for bug "Bug#43138: DROP DATABASE failure Follow-up for fix for bug "Bug#43138: DROP DATABASE failure does not clean up message list". Fixed drop.test failure under non-debug server by moving part of test dependent on debug-only feature to separate .test file, which won't be run for non-debug versions of server.

2770	Bug #42461 Plugins: st_mysql_lex_string differs between plug... Bug #42461 Plugins: st_mysql_lex_string differs between plugin.h and m_string.h include/m_string.h and include/mysql/plugin.h had different definition of the type of the length attribute (size_t vs. unsigned int). Decided to use size_t as the common type, as this is the type used in the Single Unix Specification everywhere a string's length is given. No specific test case is added, as several existing test cases use MYSQL_LEX_STRING from plugins (in particular the maria suite).	Magne Mahre	15 years ago
2769	Added a test to check if the file name length exceeds the OS... Added a test to check if the file name length exceeds the OS/platform maximum file name length.	Magne Mahre	15 years ago
2768	Fix for Bug#43138: DROP DATABASE failure does not clean up m... Fix for Bug#43138: DROP DATABASE failure does not clean up message list. The problem was that the high-level function mysql_rm_db() invoked low-level mysql_rm_table_part2(), which reported low-level error (Unknown table) if SE refused to delete a table. Also when mysql_rm_table_part2() reported an error, it didn't add corresponding warning into the list (because it is used from other places where such behaviour is required). The fix is to 1. Remove no_warnings_for_error usage from sql_table.cc 2. Improve internal error handler support in THD, so that a stack of error handlers is allowed. 3. Create an internal error handler (Drop_table_error_handler) to silence useless warnings. 4. Use the handler in DROP DATABASE and DROP TABLE statements.	Alexander Nozdrin	15 years ago

Bug#41971: Thread state on embedded server is always "Writing to net" The problem is that the state of a thread on a embedded server is always displayed as "Writing to net", which is wrong as there is no "network" in the embedded server. The solution is only exclude, on a embedded server, the thread state conditions that are related to network operations. Other thread states related to waiting on conditions or other operations are preserved.	Davi Arnaut	15 years ago
2762	Patch for Bug#37795: main.innodb_mysql crashes randomly. Patch for Bug#37795: main.innodb_mysql crashes randomly. It was a test case problem: one 'reap' statement was forgotten.	Alexander Nozdrin	15 years ago
2761	Bug #33693 general log name and location depend on PID file,... Bug #33693 general log name and location depend on PID file, not on predefined values The default name of the PID file was constructed, as documented, based on the hostname. This name was subsequently used as the base for the general log file name. If the name of the PID file was overridden in the configuration, and no explicit name was set for the general log file, the path location for the PID file was used also for the general log file. A new variable, 'default_logfile_name', has been introduced. This name is constructed based on the hostname, and is then used to construct both the PID file and the general log file. The general log file will now, unless explicitly set, be located in the server data directory (as documentated in the server docs)	Magne Mahre	15 years ago
2760	Patch for Bug#39542: main.trigger_compat fails sporadically ... Patch for Bug#39542: main.trigger_compat fails sporadically on windows. The patch actually enhances mysqltest directives -- 'move_file' has been introduced.	Alexander Nozdrin	15 years ago
2759	Bug #38124 "general_log_file" variable silently unset when u... Bug #38124 "general_log_file" variable silently unset when using expression When assigning the new string value to the variable, the Item::str_value member was used. This is not according to the protocol. str_value is an internal member used for temporary assignments, and is not consistently set for all string operations. It is set for constant strings, so it would work in these cases, but not for string functions (concat, substr, etc.) The correct approach is to use Item::val_str(..) to evaluate and retrieve the string.
