so.. |
| 10:49 |
VanessaE |
since I'm on sqlite3 for the player backend..... |
| 10:50 |
VanessaE |
I've since found a good workaround for the one reason I had to edit a player file (to manually reset a player's homedecor wardrobe skin) |
| 10:50 |
VanessaE |
but, what if I need to examine, erase, or modify a player's inventory? |
| 10:51 |
VanessaE |
what do I do in that case? is there a good mod to manage such things? |
| 10:55 |
ANAND |
VanessaE: https://sqlitebrowser.org/ ;) |
| 10:56 |
ANAND |
Bc sqlite3 isn't exposed to our Lua API yet |
| 11:10 |
VanessaE |
well |
| 11:10 |
VanessaE |
I don't mean database-level access in-game |
| 11:11 |
VanessaE |
more like if there's some mod that can say list the player's inventory, delete one or more items, using the usual API calls |
| 11:11 |
VanessaE |
stuff like that |

Hi guys^^ -> modstorage:get_int(somename) ... if somename doesn't exist in the storage will it return "" or nil? I know it returns "" for strings at least |
| 14:04 |
|
Ganome317 joined #minetest-hub |
| 14:08 |
IhrFussel |
Or it could return '0' ... I don't find info on the behavior of the different storage methods |
| 14:09 |
VanessaE |
that on' |
| 14:09 |
VanessaE |
klfjdkjhjfhd |
| 14:09 |
VanessaE |
that one's another good candidate for using a proper database backend, if it doesn't alreayd |
| 14:09 |
VanessaE |
I have thousands of files created by that damned thing |
| 14:10 |
IhrFussel |
VanessaE, do you know what get_int() returns in the case of 'non-existent'? |
| 14:10 |
VanessaE |
idk |
| 14:13 |
IhrFussel |
Or I wonder if I can set something via set_int() and later retrieve it via get_string() |
| 14:17 |
ANAND |
get_int returns 0 if non-existent |
| 14:18 |
ANAND |
get_string returns "" |
| 14:18 |
IhrFussel |
So set_int(somename,0) deletes the value from the storage then? |
| 14:19 |
ANAND |
Use set_string(somename, "") to delete a key |
| 14:19 |
ANAND |
The docs only mention passing "" to delete a key |
| 14:19 |
ANAND |
See https://github.com/minetest/minetest/blob/38b94f248ad2473b8c49e9832215071e8a79944f/doc/lua_api.txt#L5053 |

I hope modstorage is significantly faster than reading txt files with values |
| 14:30 |
IhrFussel |
And thanks ANAND |
| 14:32 |
ANAND |
Yw :) |
| 14:34 |
VanessaE |
so what's the difference between modstorage and that annoying datastorage mod? |
| 14:34 |
VanessaE |
does anything even use the latter anymore? |
| 14:34 |
IhrFussel |
How do I loop through the whole mod storage? Is it just key,value in pairs(modstorage:to_table()) ? |
| 14:36 |
ANAND |
IhrFussel: Since mod storage uses plain text files behind the scenes, you'll only get rid of the additional Lua->C++ overhead by using it, which might not have a noticeable increase in speed in most cases. |
| 14:36 |
ANAND |
And yes, that's probably the best (and only) way to iterate over mod storage |
| 14:43 |
|
aerozoic joined #minetest-hub |
| 14:47 |
IhrFussel |
I thought the whole mod storage data stays in-memory the whole time and just gets flushed to the file on server map save interval |
| 14:48 |
IhrFussel |
Like player attributes/player meta |
| 15:09 |
IhrFussel |
I get 'attempt to compare number with nil' so something is not correct about 'for key, value in pairs(modstorage:to_table()) do if tonumber(value) > 100 then blah end end |
| 15:12 |
rubenwardy |
value is not a number |
| 15:12 |
rubenwardy |
ie: maybe it's something like "asnbas" |
| 15:14 |
IhrFussel |
Then how do I get the number I store? |
| 15:14 |
IhrFussel |
I store via set_string(playername,number) |
| 15:14 |
rubenwardy |
you t |
| 15:14 |
rubenwardy |
try doing print(value) |
| 15:19 |
IhrFussel |
key is 'fields' |
| 15:22 |
IhrFussel |
to_table() — returns nil or {fields = {...}, inventory = {list1 = {}, ...}} |
| 15:22 |
IhrFussel |
Why so complicated? |

Hi tenplus1 ... can you help iterating through modstorage? |
| 15:27 |
tenplus1 |
hi fussel, explain please ? |
| 15:27 |
IhrFussel |
for key, value in pairs(modstore:to_table()) do print(key) end << key is just 'fields' |
| 15:28 |
IhrFussel |
'value' is nil |
| 15:28 |
rubenwardy |
IhrFussel: because node meta data can contain both fields and inventories |
| 15:28 |
tenplus1 |
hey ruben |
| 15:28 |
IhrFussel |
Why did you not remove the node meta stuff from modstorage? That is useless |
| 15:28 |
tenplus1 |
is something wrong with one of my mods ? what's with the modstorage |
| 15:29 |
rubenwardy |
Mod storage uses the meta API |
| 15:29 |
rubenwardy |
same as item meta, node meta, and player meta |
| 15:29 |
rubenwardy |
it's consistent |
| 15:30 |
tenplus1 |
o.O |
| 15:30 |
IhrFussel |
I just need a way to loop through the whole modstorage data with 2 vars one for each player name and one for the value associated with the playername |
| 15:30 |
rubenwardy |
for key, value in pairs(modstore:to_table().fields) |
| 15:30 |
rubenwardy |
also, you should use player meta if the data isn't needed when the player is offline |
| 15:31 |
IhrFussel |
It is needed at all times...part of a ranking system |
| 15:31 |
rubenwardy |
also, be aware that :to_table() is much slower than minetest.deserialize(meta:get("singlekey")) |
| 15:32 |
rubenwardy |
with the only backend available |
| 15:32 |
rubenwardy |
if an SQLite backend is added for mod storage, then using separate keys could be better |

IhrFussel |
Are we talking in terms of ms difference? |
| 15:34 |
IhrFussel |
Or rather µs |
| 15:36 |
rubenwardy |
for ContentDB, the difference is in seconds |
| 15:36 |
rubenwardy |
although, actually that may have been because of other problems |
| 15:36 |
rubenwardy |
don't think I reserved the size of the vector |
| 15:41 |
rubenwardy |
well, "seconds" -> 0.5 secs maybe |
| 15:47 |
sofar |
seems having an in-game sqlite api would be neat by now |
| 15:47 |
sofar |
as an alternative to mod_storage |
| 15:49 |
rubenwardy |
yeah |
| 15:50 |
rubenwardy |
mod_storage and meta are key-value stores - they don't work well with lists or list of structs |
| 15:51 |
rubenwardy |
local records = minetest.get_record_store("mydb") -- mod local like mod storage |
| 15:51 |
rubenwardy |
records:insert({ a = "a", b = "b" }) |
| 15:51 |
rubenwardy |
records:find_all({ a = "a" }) |
| 15:51 |
rubenwardy |
etc |
| 15:51 |
rubenwardy |
not sure how to do schema |
| 15:52 |
rubenwardy |
exposing SQLite directly could be a bad idea: |
| 15:52 |
rubenwardy |
- not portable between sqlite / postgresql / etc |
| 15:52 |
rubenwardy |
- may not be secure |
| 15:52 |
rubenwardy |
record stores should probably not be in the CSM api |
| 15:53 |
rubenwardy |
hmmm |
| 15:55 |
sofar |
portability wouldn't be a problem if it was just sqlite3 |
| 15:55 |
rubenwardy |
yeah, that gets rid of #1 |

oops |
| 15:56 |
rubenwardy |
plus, it would probably be faster to use SQLite directly than PostgreSQL with a limited makeshift ORM |
| 15:57 |
sofar |
I don't think we want to expose all of lsqlite3 anyway |
| 16:12 |
IhrFussel |
Can any of you tell me why this custom function 'spairs' from here https://stackoverflow.com/a/15706820 lists the highest value as last value when I call it with 'for k,v in spairs(HighScore, function(t,a,b) return t[b] < t[a] end) do print(k,v) end' ? |

tries to sneak a created-at and last-modified-by-a-player-at-timestamp into the database |

IhrFussel |
All other values are sorted from highest to lowest but the most high value comes last for some reason |

did you try the live beta image? |
| 16:48 |
sofar |
or the installer? |
| 16:48 |
tenplus1 |
that's ok... currently testing kubuntu 19.04 pre-release |
| 16:48 |
tenplus1 |
yep, tried all images and nothing boots |
| 16:48 |
sofar |
UEFI or plain BIOS? |
| 16:48 |
sofar |
also, what HW? |
| 16:49 |
tenplus1 |
acer apire r3700 with nvidia ion v.2, atom 1.8 ht, 4gb ddr3 |
| 16:49 |
sofar |
euh |
| 16:49 |
sofar |
wow yeah that's an interesting piece of HW |
| 16:49 |
sofar |
is it even 64bit? |
| 16:49 |
tenplus1 |
yup |
| 16:49 |
sofar |
well, atom, but, does it have a 64bit UEFI ? |
| 16:49 |
tenplus1 |
no uefi at all |
| 16:50 |
sofar |
I think that's your problem |
| 16:50 |
tenplus1 |
so clear linux requires this ? |
| 16:50 |
sofar |
it gets a lot more complicated without UEFI |
| 16:50 |
tenplus1 |
bummer, will stick with kubuntu for now then... |
| 16:50 |
tenplus1 |
thanks dude |
| 16:50 |
sofar |
we have special images for non-UEFI atm |
| 16:52 |
tenplus1 |
ohhh, never saw those, will recheck site |
| 16:52 |
sofar |
they're labelled `legacy` but I don't vouch for their quality :) |
| 16:53 |
sofar |
you probably want to try: https://cdn.download.clearlinux.org/current/clear-28880-installer.iso.xz |
| 16:54 |
sofar |
if that doesn't work just wait and I'll let you know when we have something that might work in your case :) |
| 16:54 |
tenplus1 |
downloading now, thx |
| 16:56 |
IhrFussel |
to_table() returns the values as STRINGS correct? Cause even though I store them as INTs a function that gets passed the modstore:to_table().fields complains about comparing number to string |
| 16:56 |
sofar |
the gfx will be challenging though, we only have the OSS drivers, and given that it's the ION, I'm not even sure we support it atm |
| 16:57 |

<fingers crossed> cause the 5.0 kernel has a few issues at the moment with xorg detection |
