0.12.0 - 2020-03-02

  • Added .meta sub-set of functions to execute lock-free metadata requests using /*snapshot execution*/ SQL hint;

  • Deprecated some .ext functions executing queries similar to .meta (code remains in place for compatibility);

  • Added connection option connection_timeout in addition to existing option socket_timeout. Connection_timeout is applied during initial connection only and socket_timeout is applied for all other requests, including actual login procedure.

  • Reworked error handling for HTTP transport to take care of even more complex failure scenarios;

  • Reworked internals of SQL builder for IMPORT / EXPORT parameters;

  • ExaStatement should now properly release result set handle after fetching and object termination;

  • Removed weakref, it was not related to previous garbage collector problems;

  • Renamed previously added .connection_time to .login_time, which is more accurate name for this timer;

  • Query text length in ExaQueryError exception is now limited to 20k characters to prevent logs from bloating;

  • Fixed open_schema function with quote_ident=True;

  • .last_statement() now always returns last ExaStatement executed on this connection. Previously it was skipping technical queries from ExaExtension (.ext);
