VanessaE |
has anyone else had problems with minetest just randomly deleting auth.txt? |
| 18:42 |
Shara |
VanessaE: Yup. Lost mine a few weeks back. |
| 18:42 |
VanessaE |
and it's not an out-of-space issue? |
| 18:42 |
Shara |
Definitely not. |
| 18:42 |
VanessaE |
ok |
| 18:42 |
VanessaE |
because it just hit two of my servers last night. |
| 18:43 |
VanessaE |
(and I'm fairly sure it's not running out of space) |
| 18:43 |
Shara |
Any idea of the size of the files? |
| 18:43 |
VanessaE |
what should have been 679kB and around 2000 entries was down to 6kB and half a dozen or so entries. |
| 18:44 |
sfan5 |
oh so it was losing entries? |
| 18:44 |
VanessaE |
no, it's more like it deleted the whole file |
| 18:44 |
VanessaE |
because what was there in the remaining file was clearly NEW accounts |
| 18:44 |
Shara |
It was the same for me, but a much bigger file when it hapened. |
| 18:45 |
Shara |
(thankfully I had a backup) |
| 18:45 |
sfan5 |
hm i don't think the file saving code was changed recently |
| 18:45 |
Shara |
sfan5: for me it was on current stable |
| 18:45 |
nerzhul |
sfan5, no |
| 18:45 |
VanessaE |
I keep backups, but space IS at a premium for me, so only the past day's worth |
| 18:46 |
VanessaE |
this is 0.4.16 release |
| 18:46 |
VanessaE |
(I don't track git) |
| 18:47 |
VanessaE |
wasn't there some change just before 0.4.16 went out to default player accounts to sqlite? |
| 18:48 |
sfan5 |
but that's not related to auth.txt |
| 18:48 |
sfan5 |
filesys::safeWriteToFile() wasn't touched in over 2 years |
| 18:48 |
VanessaE |
erm... player accounts ~= passwords and privs? :) |
| 18:48 |
sfan5 |
wait the auth handler is in lua anyway |
| 18:48 |
VanessaE |
I was thinking more along the lines of a migration bug actually |
| 18:49 |
sfan5 |
VanessaE: what? there is no support for sqlite auth.txt nor has there ever been |
| 18:49 |
VanessaE |
oh good. |
| 18:49 |
sfan5 |
what you're thinking of is player metadata (pos, inventory, attributes) |
| 18:49 |
VanessaE |
right. |
| 18:49 |
Shara |
It happened on my server at a time when there'd been no recent changes at all |
| 18:49 |
VanessaE |
In any case, it's happened to three of my servers (two last night, one some weeks ago), and Shara's, and fwiw the files in players/ were all still there |
| 18:50 |
sfan5 |
well this is terribly open to corruption https://github.com/minetest/minetest/blob/master/builtin/game/auth.lua#L45 |
| 18:50 |
VanessaE |
the only thing I noticed that was questionable was a couple of invalid entries in auth.txt when I restored from backup |
| 18:50 |
Shara |
I assumed in my case it was because the auth file got ridiculously big, and text files of that size aren't great |
| 18:50 |
VanessaE |
but that gets caught at bootup. |
| 18:50 |
sfan5 |
it should be doing create new + rename instead of rewriting the file in-place |
| 18:51 |
sfan5 |
hm there's no lua api for safeWriteToFile() |
| 18:52 |
sfan5 |
who thought this was a good idea? |
| 18:54 |
VanessaE |
holy fuckballs |
| 18:54 |
VanessaE |
root daconcepts:/home/minetest/.minetest/worlds/Survival_World# ls -lah rollback.sqlite |
| 18:54 |
VanessaE |
-rw-r--r-- 1 minetest minetest 160G Nov 1 19:53 rollback.sqlite |
| 18:54 |
VanessaE |
um, excuse me? |
| 18:54 |
VanessaE |
can we PLEASE get something done about that? |
| 18:55 |
VanessaE |
technic machines and mesecons stuff, and other automated activities get recorded into the rollback log and there's no way to prevent it |
| 18:55 |
nerzhul |
disable it or purge it yourself ? :p |
| 18:55 |
* VanessaE |
sighs and disables rollback |
| 18:56 |
sfan5 |
the problem with rollback is that it was never maintained in any way |
| 19:00 |
VanessaE |
nerzhul: I used to purge them via a script but for whatever reason, it either quit working right or it was extremely slow, so I stopped doing it (and even if I had, it was set to purge >1 month entries, and I still ended up with massive multi-gig logs) |

lol sqlite, 160GB database... => slow |
| 19:01 |
nerzhul |
i think you don't have indexes on what your query for deletion |
| 19:01 |
nerzhul |
don't expect good performance for sqlite over 1GB |
| 19:01 |
VanessaE |
# echo "DELETE FROM action WHERE timestamp < `expr \`date +%s\` - 604800`;" | sqlite3 rollback.sqlite |
| 19:01 |
VanessaE |
you were saying? |
| 19:01 |
nerzhul |
is there any index on timestamp in rollback db ? i don't think |
| 19:02 |
nerzhul |
then sqlite will look at all records for remove some |
| 19:02 |
VanessaE |
and, again, the root problem is there is no way to prevent actions from being recorded into the rollback, else technic and mesecons and the like would use such, and the log would be managable. |
| 19:02 |
VanessaE |
manageable* |
| 19:03 |
VanessaE |
I asked for this like 2 years ago |
| 19:03 |
sfan5 |
nerzhul: i think sqlite automatically creates indexes, not sure |
| 19:03 |
nerzhul |
sfan5, absolutely not |
| 19:03 |
sfan5 |
maybe only in some cases ¯\_(ツ)_/¯ |
| 19:03 |
nerzhul |
no |
| 19:03 |
nerzhul |
it's like every relational db |
| 19:04 |
nerzhul |
primary keys are indexed (normal), other fields are not |
| 19:04 |
nerzhul |
sfan5, hopefully, imagine sqlite indexing mapblocks themselves :p |
| 19:04 |
sfan5 |
that would be stupid indeed |
| 19:36 |
Fixer |
looks like critical bug, file a bug |
| 19:36 |
shivajiva |
Vanessa: you could try sauth and if you use sqlite for the player data you have an easy way of cleaning orphaned entries |
| 19:38 |
Fixer |
VanessaE: vote here https://github.com/minetest/minetest/issues/6525 |
| 19:40 |
VanessaE |
I'll let Shara do it. |
| 19:40 |
VanessaE |
(to file the bug I mean) |
| 19:42 |
Shara |
I've already moved one server to sauth and will move the other over as well. |
| 19:42 |
Shara |
Don't know why we're using a text file for this. |
| 19:43 |
Fixer |
Shara: can you file a bugreport for that file corruption? |
| 19:43 |
Shara |
I don't really know what to say about it, beyond "auth.txt ate itself" |
| 19:44 |
Fixer |
Shara: describe the stuff you described here, that will be enough |
| 19:46 |
Shara |
Sure, give me a moment |
