10:53 VanessaE how do I migrate a server's players from files-format to whatever the new database format is?
10:53 Krock --migrate-players <new backend>
10:54 Krock minetestserver --help
10:54 Krock same for auth: --migrate-auth <new backend>
10:54 VanessaE what backends are supported?
10:55 Krock https://wiki.minetest.net/Database_backends#Comparison_table
10:55 Krock qlite3, postgresql, dummy, plaintext
10:56 VanessaE ah.  didn't realize map backends also could apply to players.
10:56 Krock it's the same database type, but not the same database file
10:56 VanessaE right
10:56 Krock if we already have sqlite3 support, then why not use it for other storages :D ?
10:56 VanessaE right
10:57 VanessaE or in my case, leveldb
10:57 Krock yeah, but that's an optional dependency
10:57 VanessaE yeah, but my servers already use it
10:57 Krock ah, well then you don't have additional efforts to do
10:58 Krock too bad leveldb is not used on players backends
10:58 VanessaE ok, then sqlite it is.

11:50 VanessaE jeesh, I'm glad I only have to do this once.  migrating players to sqlite is slllllllooooooooowwwwww on spinning rust :P
12:22 sfan5 does minetest not use a transaction for that? writing lots of records shouldn't be slow
12:27 VanessaE I'm pretty sure the slow part is reading the individual player files :)
12:27 VanessaE anyways, that's all done now.
12:32 rubenwardy I have a lot of concerns about database implementations in minetest
12:41 Emerald2 Milan said they're still having memleak issues after migrating the players to sqlite3.
13:01 VanessaE well in this case, I migrated because when you've got almost 400,000 player files, backups tend to get...slow.
13:01 VanessaE (even once I deleted all files modified more than 90 days ago, there were over 8000)
13:05 VanessaE (I figure if a player hasn't been online in the last 90 days on that server, or the last 6 months on my others, they're just plain gone, and it's safe to delete their player file)
13:05 VanessaE (but keep their auth.txt entry of course)

14:19 Sokomine oh. i usually tend to stay away more than 90 days between visits. but if auth and especially protection is kept (as is on vanessaes servers), that's no big problem
14:44 VanessaE correct
14:44 VanessaE only old players/* files were deleted.
14:45 VanessaE no changes to auth, protection, etc.
14:45 VanessaE and I'm only doing it once :)
14:49 rubenwardy CTF doesn't even keep players/* files between loging
14:49 rubenwardy *logins
14:51 VanessaE makes sense
15:26 * Sokomine nods
15:27 Sokomine what's the current state of security? my handle_schematics mod does want to read folders and files after runtime. part of its purpose is to be a file browser for schematics. security is so tight that that's not possible. but pehraps something changed in the last month?
15:30 Krock you can still add an exception for that mod
