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) |

OQGraph storage engine v3 Copyright (C) 2007-2014 Arjen G Lentz & Antony T Curtis for Open Query, & Andrew McDonnell The Open Query GRAPH engine (OQGRAPH) is a computation engine allowing hierarchies and more complex graph structures to be handled in a relational fashion. In a nutshell, tree structures and friend-of-a-friend style searches can now be done using standard SQL syntax, and results joined onto other tables. Based on a concept by Arjen Lentz v3 implementation by Antony Curtis, Arjen Lentz, Andrew McDonnell For more information, documentation, support, enhancement engineering, see http://openquery.com/graph or contact graph@openquery.com INSTALLATION OQGraph requires at least version 1.40.0 of the Boost Graph library. To obtain a copy of the Boost library, see http://www.boost.org/ This can be obtained in Debian Wheezy by `apt-get install libboost-graph-dev` OQGraph requires libjudy - http://judy.sourceforge.net/ This can be obtained in Debian Wheezy by `apt-get install libjudy-dev` BUILD (example) cd path/to/maria/source mkdir build # use symlink to scratch cd build CONFIGURE="-DWITH_EXTRA_CHARSETS=complex -DWITH_PLUGIN_ARIA=1 -DWITH_READLINE=1 -DWITH_SSL=bundled -DWITH_MAX=1 -DWITH_EMBEDDED_SERVER=1" cmake .. $CONFIGURE make -j5 mysql-test-run --suite oqgraph
