* MDEV-15091 : Windows, 64bit: reenable and fix warning C4267 (conversion from ↵Vladislav Vaintroub2018-02-061-5/+5
| | | | | | | | | | | 'size_t' to 'type', possible loss of data) Handle string length as size_t, consistently (almost always:)) Change function prototypes to accept size_t, where in the past ulong or uint were used. change local/member variables to size_t when appropriate. This fix excludes rocksdb, spider,spider, sphinx and connect for now.
* Change C_STRING_WITH_LEN to STRING_WITH_LENMonty2018-01-301-2/+2
| | | | | | | | | This preserves const str for constant strings Other things - A few variables where changed from LEX_STRING to LEX_CSTRING - Incident_log_event::Incident_log_event and record_incident where changed to take LEX_CSTRING* as an argument instead of LEX_STRING
* Changing field::field_name and Item::name to LEX_CSTRINGMonty2017-04-231-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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)

* Makeing rpl_filter for each Master_info.Lixun Peng2013-04-161-0/+12
| | | | | | | | | | | | | | Users can set different repplication filter rules for each replication connection, in my.cnf or command line. But the rules set online will not record in master.info, it means if users restart MySQL, these rules will lose. So if users wantn't their replication filter rules lose, they should write the rules in my.cnf. Users can set rules by 2 ways: 1. Online SET command, "SET connection_name.replication_filter_settings = rules;". 2. In my.cnf, "connection_name.replication_filter_settings = rules". If no connection_name in my.cnf, this rule will apply for ALL replication connection. If no connetion_name in SET statement, this rull will apply for default_connection_name.
