Fixes

Major

  • Add support for 'grave accent' (`) for SET statements parsing: #3479.
    • Previously grave accents break the detection of SET statements, like SET `group_concat_max_len` = 2048, this is now fixed.
  • Added client information for multi-statements parsing error message: #3487.
  • Add support for comments in 'USE' statements: #3493.
  • Fixed memory leak induced by 'stmts' not being closed when failed to prepare. #3544
  • Fixed possible mismatch of CLIENT_DEPRECATE_EOF in sessions using fast_forward: #commit

  • Fixed memory corruption reported by ASAN due to unexpected packet by 'mysqlsh': #3554
  • Fixed 'heap-buffer-overflow' detected by ASAN in 'generate_show_fields_from': #3554
  • Fixed memory leak detected by ASAN during 'PROXYSQL SHUTDOWN SLOW': #3554
  • Fixed 'strcat-param-overlap' found by ASAN in 'IsKeepMultiplexEnabledVariables': #3554
  • Fixed 'stack-buffer-overflow' found by ASAN during SHA1 generation: #3554
  • Fixed double-free memory corruption due to unitialized memory in prepared statements bind buffers: #3546
  • Fixed invalid bind of prepared statement params when 'new_params_bound_flag' is not provided: #commit
  • Fixed copy of data when to MYSQL_TS structure for prepared statements when length is '0': #commit

Minor

  • Fixed default 'mysql-default_query_timeout' range into the one specified in doc. With values:
    • Minimum: 1000.
    • Maximum: 1728000000.
  • Fixed uninitialised value in MySQL_Monitor_State_Data(): #commit
  • Changing pt-heartbeat query from MIN to MAX matching pmp-check-mysql-replication-delay default behavior: #3514

Enhancements

  • Added more verbosity when mysql_real_connect() fails: #commit
  • Added client information to error generated when multi-statement command fails to be parsed: #3488
