[Maria-discuss] Repos empty?
by William Edwards 15 Aug '22

15 Aug '22

Hello, The Debian repos @ https://mariadb.org/download/?t=repo-config don't seem to contain any packages and no Release file anymore. Last updated yesterday at 18:41 (IDK which timezone). E.g. http://ams2.mirrors.digitalocean.com/mariadb/repo/10.3/debian/dists/buster/… (the issue isn't with this specific mirror). When choosing a repo on mariadb.org, the error "An error occured. The mirrors could not be loaded." is shown. -- With kind regards, William Edwards

[Maria-discuss] mysql 5.5 client vs mariadb 10 server
by Oliver 22 Mar '22

Hi, I'm sorry for the question if it is clear that it isn't possible. I'm trying connect from a mysql 5.5.56 client against a mariadb 10 server and I'm having the next error: ERROR 2003 (HY000): Can't connect to MySQL server on 'server' (10061) Subnet source is allowed in mariadb server and grant is given for 'root'@'source_server', it is allowed both IP and hostname. So not sure if it is config problem or compatibility problem. Someone knows please? Thanks beforehand. P.D.: I can connect using dbeaver from my computer client using mysql binaries (but not sure what mysql client version uses dbeaver). Cheers...

[Maria-discuss] History Length: Purge-able vs. Not Purge-able metrics
by mariadb＠Biblestuph.com 10 Mar '22

Greetings, I know I can get the current undo log history length via: > show status like '%history%'; +----------------------------+-------+ | Variable_name | Value | +----------------------------+-------+ | Innodb_history_list_length | 854 | +----------------------------+-------+ but my understanding is that at any given point in time that number represents both the records that can be purged because they are no longer needed by any current transactions (and the purge threads for whatever reason haven't gotten to them yet), as well as those that cannot be purged yet because there are current transactions running that may still need them. So the question is, is there any way to know the difference between those two? I.E., how many are waiting to be purged and how many cannot yet be purged? And a related question. Will the undo log size (the physical size of the file) grow even when there are many entries in the history that can be purged first? Or are those unneeded records purged first and that space reused before the undo log is made larger? Or perhaps I'm mis-understanding the process? TIA, Dan
