Release Overview Highlights

New Features

Although only bug fixes are supposed to go into ProxySQL 2.0, we had to introduce a few minor new features:

  • A client can force ProxySQL to run a query in a new connection using a query annotation using create_new_connection=1 in a comment. For example SELECT /* create_new_connection=1 */ 1 . See #2874
  • ProxySQL Version checker checks for new version every 24 hours

Bug fixes

  • ProxySQL could crash if stats_mysql_processlist was queried while a client connection wasn’t fully initialized
  • Improved the handling of charsets and session variables, and removed several deprecated global variables
  • The value of stats_mysql_connection_pool.Queries_GTID_sync was always 0 from 2.0.10 till 2.0.12
  • Fixed several bugs in the parsing of SET statements
  • Command COM_FIELD_LIST could generate an error if the table is a keyword
  • Internal mysql_data_stream was not correctly reset in case of change user
  • Variable mysql-default_track_gtids was being ignored
  • a large query cache was causing an interger overflow when computing the size of the query cache itself
  • PXC nodes were not being re-enabled after pxc_maint_mode was set to DISABLED
  • Fixed invalid path for logrotate, in case you have installed 2.0.12 you will need to run “rm -fr /etc/logrotate.d/proxysql” to delete the invalid configuration before installing 2.0.13
