Hi Vladislav!
i did some initial work, check if i'm going to the right direction:
https://mariadb.atlassian.net/browse/MDEV-5019
something todo...
ENUM('Y','N'), i never used... i will try some search at sql_show.cc to get
this information
thd->thread_id, thd->query_id, is listener, is waiting
i didn't found information how could i get the thd, or how to know if a
thread is the listener, or a thread is waiting
i know that i have the all_groups[].listener to get listener, but i don't
know how to check for example if a waiting_threads is the listener or not
about thread waiting, i didn't understand yet where i could check if it's
waiting or not
well just first steps, i didn't compiled yet, just write the scratch =)
thanks!!
