* Enusure that my_global.h is included firstMichael Widenius2017-08-241-1/+1
| | | | | | | | | | - Added sql/mariadb.h file that should be included first by files in sql directory, if sql_plugin.h is not used (sql_plugin.h adds SHOW variables that must be done before my_global.h is included) - Removed a lot of include my_global.h from include files - Removed include's of some files that my_global.h automatically includes - Removed duplicated include's of my_sys.h - Replaced include my_config.h with my_global.h
* Changing field::field_name and Item::name to LEX_CSTRINGMonty2017-04-231-9/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Benefits of this patch: - Removed a lot of calls to strlen(), especially for field_string - Strings generated by parser are now const strings, less chance of accidently changing a string - Removed a lot of calls with LEX_STRING as parameter (changed to pointer) - More uniform code - Item::name_length was not kept up to date. Now fixed - Several bugs found and fixed (Access to null pointers, access of freed memory, wrong arguments to printf like functions) - Removed a lot of casts from (const char*) to (char*) Changes: - This caused some ABI changes - lex_string_set now uses LEX_CSTRING - Some fucntions are now taking const char* instead of char* - Create_field::change and after changed to LEX_CSTRING - handler::connect_string, comment and engine_name() changed to LEX_CSTRING - Checked printf() related calls to find bugs. Found and fixed several errors in old code. - A lot of changes from LEX_STRING to LEX_CSTRING, especially related to parsing and events. - Some changes from LEX_STRING and LEX_STRING & to LEX_CSTRING* - Some changes for char* to const char* - Added printf argument checking for my_snprintf() - Introduced null_clex_str, star_clex_string, temp_lex_str to simplify code - Added item_empty_name and item_used_name to be able to distingush between items that was given an empty name and items that was not given a name This is used in sql_yacc.yy to know when to give an item a name. - select table_name."*' is not anymore same as table_name.* - removed not used function Item::rename() - Added comparision of item->name_length before some calls to my_strcasecmp() to speed up comparison - Moved Item_sp_variable::make_field() from item.h to item.cc - Some minimal code changes to avoid copying to const char * - Fixed wrong error message in wsrep_mysql_parse() - Fixed wrong code in find_field_in_natural_join() where real_item() was set when it shouldn't - ER_ERROR_ON_RENAME was used with extra arguments. - Removed some (wrong) ER_OUTOFMEMORY, as alloc_root will already give the error. TODO: - Check possible unsafe casts in plugin/auth_examples/qa_auth_interface.c - Change code to not modify LEX_CSTRING for database name (as part of lower_case_table_names)
* Fix many -Wconversion warnings.Marko Mäkelä2017-03-071-10/+10
| | | | | | | | | | | | | | | | | | | Define my_thread_id as an unsigned type, to avoid mismatch with ulonglong. Change some parameters to this type. Use size_t in a few more places. Declare many flag constants as unsigned to avoid sign mismatch when shifting bits or applying the unary ~ operator. When applying the unary ~ operator to enum constants, explictly cast the result to an unsigned type, because enum constants can be treated as signed. In InnoDB, change the source code line number parameters from ulint to unsigned type. Also, make some InnoDB functions return a narrower type (unsigned or uint32_t instead of ulint; bool instead of ibool).

So --plugin-load can be considered a composite option consisting of resetting the plugin load list and then calling --plugin-load-add to process the argument. Note that the order in which you specify --plugin-load and --plugin-load-add is important : "--plugin-load=x --plugin-load-add=y" will be equivalent to "--plugin-load=x,y" whereas "--plugin-load-add=y --plugin-load=x" will be equivalent to "plugin-load=x". Incompatible change : the --help --verbose command will no longer print the --plugin-load variable's values (as it doesn't have one). Otherwise both --plugin-load and --plugin-load-add are mentioned in it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
