Release date: 2019-08-14

Compared to v2.0.5, ProxySQL 2.0.6 introduces the following new features, bugs fixes and enhancements:

New features:

  • Support for SELECT statements that acquires locks. Up to 2.0.5 , only SELECT FOR UPDATE are supported. Now support is extended to:
    • SELECT ... FOR SHARE
    • SELECT ... LOCK IN SHARE MODE
    • SELECT ... FOR (UPDATE|SHARE) [OF ...] (NOWAIT|SKIP LOCKED)
  • Reject connections with unknown charset.
  • proxysql --version now prints to stdout and not stderr
    ​* Add support for COM_FIELD_LIST commands.
    ​* If SET statement is used in multi-statements commands or if parsing of SET statement it is not successful, both multiplexing and query routing is disabled. The client remains bind to a single backend connections.
    ​* ProxySQL now sends GTID informations ( SESSION_TRACK_GTIDS) to client #2120
    ​* Clients capabilities flags CLIENT_FOUND_ROWS , CLIENT_MULTI_RESULTS and CLIENT_MULTI_STATEMENTS are now tracked, and backend connections will have the same flags #2121 and #2125
    ​* ​Various enhancements on AWS Aurora module. Mostly support for both max_lag_ms and min_epoch_ms as comment modifier
    ​* For security reasons, SSLv3 is now disabled #2169
    ​* If a client issueCOM_SET_OPTION commands, flag CLIENT_MULTI_STATEMENTS is changed and tracked accordingly.
    ​* Several enhancements on Query logger
    • 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
      ​​* A lot of changes to make query digest map faster:
      ​ * Extended SQLite3_result to support a mutex for concurrent rows insert.
    • Extensively rewritten get_query_digests() and get_query_digests_reset() to support multiple threads, and concurrently generate a resultset.
    • Function get_query_digests_reset() defer the deletion of objects from query digest map after generating the resultset for Admin. This drastically reduce the amount of time that query digest map is locked.
    • Rewritten get_query_digests_total_size() to make it multi-threaded.
  • If table stats_mysql_query_digest_reset is queried but not stats_mysql_query_digest, only the first one is populated.
  • If table stats_mysql_query_digest_reset is queried and also stats_mysql_query_digest, the second one is populated as a copy from the first.
  • Overall, this commit has the following effects:
    • it increases the memory usage for query digest map. On test workload, this results in 10% more memory usage
    • drastically reduces the calls to memory management
    • populating stats_mysql_query_digest_reset is 3 times faster
    • the amount of time in which query digest map is locked is reduced by 95%
      ​* Query digest now uses ? for NULL values. Behavior is controlled by global variable mysql-query_digests_replace_null #2171
      ​​* ProxySQL 2.0.6 now run on Azure. Thanks to @YYJiangLoveU for contributions
      ​ * added variable mysql-azure_enabled (disabled by default)
    • _server_host is specified as part of mysql connection options

Bug fixes:

  • Fixed a memory leak in eventlog_reader_sample.cpp
  • Fixed a bug where interrupting the execution of a prepared statement could cause a crash #2131
  • Fixed a hang in changing autocommit #2133
  • Fixed various compiler warnings
  • Fixed a bug when multiple OK packets in multi-statements would result in closed connection
  • Disable throttling for any client other than SESSION_MYSQL (no throttling for Admin) #2147
  • Create a wrapper around all the calls to sqlite3_prepare_v2 in Admin to avoid incorrect assertions
  • ProxySQL was not sending COM_PING when multiplexing was disabled #2096​
  • Do not close backend connection for error 1317
