Javier Jaramago Fernández	88dc295781	Fixed invalid handling of large packets in 'SQLite3_to_MySQL' function #3690 ... - Provided a new function to partially initialize 'MySQL_ResultSet'. - Replaced 'generate_pkt_row' in favor of 'generate_pkt_row3' for resulset writing.	4 years ago

René Cannaò	fce7a0204c	Handle binary protocol resultset with ERR #3547 ... This commit add the support of ERR packet in binary protocol resultset, for example due to MAX_EXECUTION_TIME while running a prepared statement. It also changes how EOF packets are added: instead of writing the EOF in the resultset buffer, the EOF packet is written in its own packet. This allows to easily remove it if needed. It also fix what seems (not sure) a bug in MariaDB client library, where if a prepared statement is interrupted it cannot be executed again	5 years ago
René Cannaò	beddc41b1f	Cleanup of dead code in MySQL_Protocol	5 years ago

René Cannaò	fca4055b50	Merge branch 'v2.1.1' into v2.1.0-ps_buffer	5 years ago
René Cannaò	dacea25866	Implemented MySQL_Protocol::generate_pkt_field2() ... `generate_pkt_field2` is a less generic version of `generate_pkt_field` and it is meant to be used only for queries executed on backend. The function takes a `MYSQL_FIELD` as one of its arguments, thus a lot of lengths do not need to be computed	5 years ago
René Cannaò	7921e130d2	Third commit to buffer resultsets in Prepared Statements ... * MySQL_ResultSet() stores a pointer to the PS * MySQL_ResultSet::init_with_stmt() doesn't need anymore the pointer to the PS Furthermore, it isn't anymore an "init" but an end (we will rename it) * Added MySQL_ResultSet::add_row(MYSQL_ROWS *rows) for PS only * MySQL_Protocol::generate_pkt_row3() accepts an optional row length. If passed, it will know the length of the row without computing it * MyRS initialized during ASYNC_STMT_EXECUTE_STORE_RESULT_START * Implemented throttling during ASYNC_STMT_EXECUTE_STORE_RESULT_START * MySQL_Connection::process_rows_in_ASYNC_STMT_EXECUTE_STORE_RESULT_CONT() always generates a heartbeat. For now unnecessary, and we will better tune it later * test_ps_async-t.cpp tunes mysql-threshold_resultset_size to trigger buffering More testing is required	5 years ago
René Cannaò	0171082448	Adding MySQL_ResultSet::init_with_stmt() ... This new function is meant to split MySQL_ResultSet::init() to later remove all code specific to prepared statements because it assumes it is pre-buffered	5 years ago
Javier Jaramago Fernández	7150c7d8ed	Added metadata to 'Query_Cache' entries for supporting EOF deprecation	5 years ago
René Cannaò	149530a8b2	Default eof_identifier=false in generate_pkt_OK()	5 years ago

Bibek Shrestha	53032b1c15	Define CLIENT_DEPRECATE_EOF as mariadb does not support it yet	5 years ago
Bibek Shrestha	28c01e9b4d	Send OK packet after ResultSet ... When CLIENT_DEPRECATE_EOF flag is supported by client, the first EOF packet after Metadata is not sent anymore. The EOF packet after each ResultSet is replaced by an OK packet. Signed-off-by: Bibek Shrestha <bibekshrestha@gmail.com>	5 years ago

René Cannaò	f3e7f03998	Implementation of COM_FIELD_LIST ... Port from 1.4.16 to 2.0.6	7 years ago
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	a6c53d0d12	Revert "Refactor header includes."	9 years ago
Maxim Bublis	30dbcc21a8	Refactor header includes. ... * reduce build time by 25%; * remove circular dependency on `cpp.h` and other headers. * fixes issue with `my_global.h` from mariadbclient which redefines `__attribute__`, that leads to broken STL and GCC intrinsics if `<algorithm>` wasn't included prior including this header; * fixes another issue with redefined `__attribute__` which leads to `_conn_exchange_t` not being aligned to cache line size; * removes `pthread_setstacksize` calls as `my_global.h` redefines `pthread_setstacksize` to be `pthread_dummy(0)` which led to stack size being never adjusted; * add missing include guards to some headers; * remove unused proxysql_hash.h header.	9 years ago
