René Cannaò	0831740e45	Several enhancements on Query logger ... Enhancements: - added metrics rows_affected and rows_sent - added global variable mysql-eventslog_default_log : if 1 , logging is enabled for every query unless explicitly disabled in mysql_query_rules.log . Default is 0 - added global variable mysql-eventslog_format : default is 1 (legacy format). A value of 2 enables logging in JSON format. Issue #871 Changing value at runtime causes the current file to be closed and a new one created - fixed logging for prepared statements: till 2.0.5 only some percentage of prepared statements was correctly logged Extended tables stats_mysql_query_digest and stats_mysql_query_digest_reset to also include sum_rows_affected and sum_rows_sent Extended `eventslog_reader_sample.cpp` to support the new enhancements	7 years ago

René Cannaò	7b3757a273	Remember if the current connection has an unknown transaction status ... The fix for bug #1038 was to not return a connection to the connection pool if it has an error. Although this is correct, it also has the side effect that connections coming from connection pool and failing during the first query because the connection was already broken, would be considered as possibly to run a transaction. That is incorrect. Now at connection level it is tracked if the transaction status is known or not.	8 years ago
