Michael Widenius	5f68820cd4	Fixed problem with failing mysql_upgrade when proc table was not correct. Moved out creation of performance schema tables from mysql_system_tables.sql as the performance_tables creation scripts needs a working mysql.proc to work. client/mysql_upgrade.c: Added option -V, --version debian/dist/Debian/mariadb-server-5.5.files: Added mysql_performance_tables.sql debian/dist/Ubuntu/mariadb-server-5.5.files: Added mysql_performance_tables.sql mysql-test/lib/v1/mysql-test-run.pl: Added mysql_performance_tables.sql mysql-test/mysql-test-run.pl: Added mysql_performance_tables.sql scripts/CMakeLists.txt: Moved out creation of performance schema tables from mysql_system_tables.sql as the performance_tables creation scripts needs a working mysql.proc to work scripts/mysql_install_db.sh: Added mysql_performance_tables.sql scripts/mysql_performance_tables.sql: Moved out creation of performance schema tables from mysql_system_tables.sql as the performance_tables creation scripts needs a working mysql.proc to work scripts/mysql_system_tables.sql: Move creation of performance schema tables to mysql_performance_tables.sql Added 'flush tables' to get things to work if someone deletes a table like mysql.proc before run scripts/mysql_system_tables_fix.sql: ove performance table things to mysql_performance_tables.sql storage/perfschema/pfs.cc: Fixed comment	13 years ago
Davi Arnaut	71e0ff64f0	Bug#12727287: Maintainer mode compilation fails with gcc 4.6 GCC 4.6 has new -Wunused-but-set-variable flag, which is enabled by -Wall, that causes GCC to emit a warning whenever a local variable is assigned to, but otherwise unused (aside from its declaration). Since the maintainer mode uses -Wall and -Werror, source code which triggers these warnings will be rejected. That is, these warnings become hard errors. The solution is to fix the code which triggers these specific warnings. In most of the cases, this is a welcome cleanup as code which triggers this warning is probably dead anyway. dbug/dbug.c: Unused but set. libmysqld/lib_sql.cc: Length is not necessary as the converted error message is always null-terminated. sql/item_func.cc: Make get_var_with_binlog private to this compilation unit. If a error was raised, do not attempt to evaluate the user variable as the statement execution will be interrupted anyway. sql/mysqld.cc: Use a void expression to silence the warning. Avoids the use of macros that would make the code more unreadable than it already is. sql/protocol.cc: Length is not necessary as the converted error message is always null-terminated. Remove unnecessary casts and assignment. sql/sql_class.h: Function is only used in a single compilation unit. sql/sql_load.cc: Only use the variable outside of EMBEDDED_LIBRARY. storage/innobase/btr/btr0cur.c: Do not retrieve field, only the record length is being used. storage/perfschema/pfs.cc: Use a void expression to silence the warning. tests/mysql_client_test.c: Unused but set. unittest/mysys/lf-t.c: Unused but set.	15 years ago

Marc Alff	a1d90f124f	Bug#55462 Performance schema: reduce the overhead of PFS_events_waits::m_wait_class This is a performance improvement fix. Removed the "volatile" property of PFS_events_waits::m_wait_class. Simplified the code accordingly.	15 years ago

Marc Alff	ec41287630	Bug#55087 Performance schema: optimization of the instrumentation interface This change is for performance optimization. Fixed the performance schema instrumentation interface as follows: - simplified mysql_unlock_mutex() - simplified mysql_unlock_rwlock() - simplified mysql_cond_signal() - simplified mysql_cond_broadcast() Changed the get_thread_XXX_locker apis to have one extra parameter, to provide memory to the instrumentation implementation. This API change allows to use memory provided by the caller, to avoid having to use thread local storage. Using this extra parameter will be done in a separate fix, this change is for the interface only. Adjusted all the code and unit tests accordingly.	16 years ago
Davi Arnaut	f56dd32bf7	Bug#34043: Server loops excessively in _checkchunk() when safemalloc is enabled Essentially, the problem is that safemalloc is excruciatingly slow as it checks all allocated blocks for overrun at each memory management primitive, yielding a almost exponential slowdown for the memory management functions (malloc, realloc, free). The overrun check basically consists of verifying some bytes of a block for certain magic keys, which catches some simple forms of overrun. Another minor problem is violation of aliasing rules and that its own internal list of blocks is prone to corruption. Another issue with safemalloc is rather the maintenance cost as the tool has a significant impact on the server code. Given the magnitude of memory debuggers available nowadays, especially those that are provided with the platform malloc implementation, maintenance of a in-house and largely obsolete memory debugger becomes a burden that is not worth the effort due to its slowness and lack of support for detecting more common forms of heap corruption. Since there are third-party tools that can provide the same functionality at a lower or comparable performance cost, the solution is to simply remove safemalloc. Third-party tools can provide the same functionality at a lower or comparable performance cost. The removal of safemalloc also allows a simplification of the malloc wrappers, removing quite a bit of kludge: redefinition of my_malloc, my_free and the removal of the unused second argument of my_free. Since free() always check whether the supplied pointer is null, redudant checks are also removed. Also, this patch adds unit testing for my_malloc and moves my_realloc implementation into the same file as the other memory allocation primitives. client/mysqldump.c: Pass my_free directly as its signature is compatible with the callback type -- which wasn't the case for free_table_ent.	16 years ago
Davi Arnaut	a8c288054e	Bug#53445: Build with -Wall and fix warnings that it generates Fix various mismatches between function's language linkage. Any particular function that is declared in C++ but should be callable from C must have C linkage. Note that function types with different linkages are also distinct. Thus, if a function type is declared in C code, it will have C linkage (same if declared in a extern "C" block). client/mysql.cc: Mismatch between prototype and declaration. client/mysqltest.cc: mysqltest used to be C code. Use C linkage where appropriate. cmd-line-utils/readline/input.c: Isolate unreachable code. include/my_alloc.h: Function type must have C linkage. include/my_base.h: Function type must have C linkage. include/my_global.h: Add helper macros to avoid spurious namespace indentation. include/mysql.h.pp: Update ABI file. mysys/my_gethwaddr.c: Remove stray carriage return and fix coding style. plugin/semisync/semisync_master_plugin.cc: Callback function types have C linkage. plugin/semisync/semisync_slave_plugin.cc: Callback function types have C linkage. sql/derror.cc: Expected function type has C linkage. sql/field.cc: Use helper macro and fix indentation. sql/handler.cc: Expected function type has C linkage. sql/item_sum.cc: Correct function linkages. Remove now unnecessary cast. sql/item_sum.h: Add prototypes with the appropriate linkage as otherwise they are distinct. sql/mysqld.cc: Wrap functions in C linkage mode. sql/opt_range.cc: C language linkage is ignored for class member functions. sql/partition_info.cc: Add wrapper functions with C linkage for class member functions. sql/rpl_utility.h: Use helper macro and fix indentation. sql/sql_class.cc: Change type of thd argument -- THD is a class. Use helper macro and fix indentation. sql/sql_class.h: Change type of thd argument -- THD is a class. sql/sql_select.cc: Expected function type has C linkage. sql/sql_select.h: Move prototype to sql_test.h sql/sql_show.cc: Expected function type has C linkage. sql/sql_test.cc: Fix required function prototype and fix coding style. sql/sql_test.h: Removed unnecessary export and add another. storage/myisammrg/ha_myisammrg.cc: Expected function type has C linkage. storage/perfschema/pfs.cc: PSI headers are declared with C language linkage, which also applies to function types.	16 years ago
