[Maria-developers] [Commits] 1c9da8d: MDEV-9312: storage engine not enforced during

28 Nov 2016

      Hi Nirbhay,

   if (IF_WSREP(thd->wsrep_applier,1))

    {

      plugin_thdvar_init(thd);

    }

This code in commit , breaks log writing on other nodes(In galera) , It sets
the thd->variables to global system variable.
And this

if (wsrep_emulate_bin_log || !(thd->variables.option_bits & OPTION_BIN_LOG))
  DBUG_RETURN(0);

code here make write_transaction_to_binlog() function exit.

I am unable to understand purpose of applying plugin_thdvar_init(thd);
 for wsrep_applier threads.
Because this is applied on first thread only and not applied to
remaining threads.
