René Cannaò	a53b8c2631	Loop only if flagOUT != 0	10 years ago
René Cannaò	d9b93b3937	Added new var mysql-query_processor_iterations ... When query rules are processed, even if flagOUT is set rules are processed in numerical order. This new variable allows to jump back (reset rule_id to 0) N amount of times. Using this variable is possible to implement loops. Futhermore, a loop is possible with only one rule setting flagIN=flagOUT . The default is 0. The maximum value is 1000000 .	10 years ago

Introduced also a parser for escaping strings with single quotes: double quotes are allowed without extra escaping	10 years ago

René Cannaò	d51bed1718	Reduce frequent alloc of Query_Processor_Output ... A new Query_Processor_Output (qpo) is allocated for every query. Allocation is now done once per session, thus speeding up execution time under memory profiler	10 years ago

René Cannaò	bc8c5e175a	Added column mirror_flagOUT in mysql_query_rules ... Mirroring starts when either mirror_hostgroup or mirror_flagOUT is set	10 years ago
René Cannaò	2e276f06f4	Second commit to implement mirroring ... Expanded table `mysql_query_rules` to add `mirror_hostgroup` Expanded struct `_Query_Processor_rule_t` and class `Query_Processor_Output` to support `mirror_hostgroup` Added new variable `mirror_hostgroup` in `MySQL_Session` The following logic ensure that a mirror_hostgroup set when processing the query in the original session is preserved when reprocessing the query in the mirror session: * when a new mirror session is *created* `mirror_hostgroup` is set according to the result of Query_Processor * when a mirror session is *executed* , `mirror_hostgroup` is copied into `default_hostgroup` Current limitations: * queries larger than 15MB aren't mirrorred * upgrade from 1.1 is still not possible it will wipe table mysql_query_rules	10 years ago
