11:05 rmilan it is possible to delete map blocks with mods? to reduce map size [and regenerate]
11:05 PilzAdam no
11:07 rmilan then there should be commands like /build and /mining, to change player's mapfile to modify
11:07 rmilan i mean, if i do a /build, its saved to map_build.sqlite, if mining, then map_mining.sqlite :D
11:07 rmilan and can delete mining, when the map is big and bad, and keep the built things [and generate maybe new map with chaning seed]
11:08 rmilan but it would be buggy without flatmap
11:08 PilzAdam rmilan, its on the TODO list of the core devs to only save blocks if they are modified
11:09 rmilan i know, but that would save mines also
11:09 rmilan and i often want to delete mines because its make big holes if more player mining
11:09 rmilan but its player specific :D
11:09 PilzAdam you could use rollback for that, I guess
11:09 rmilan so i could delete those nodes with script
11:10 rmilan if that will be done
11:10 rmilan anyway its hard to make save only diffs?
11:10 rmilan i mean, its not only about save the modified nodes only, others will be generated all the time?
11:10 rmilan and maybe keep in memory
11:10 rmilan some change in code, or big?
11:11 rmilan anyway sorry for asking here, but i wont bother dev channel :D
11:11 rmilan i dont even know c++, just asking :D

15:50 ShadowNinja rmilan: Saving only modified nodes would be difficult, and it might end up taking up more space as it is pretty much a rollback log in reverse and those are known to get bigger than the map. Saving only modified blocks(chunks) would be easier to implement and should reduce the map size quite a bit.
15:50 PilzAdam ShadowNinja, not nodes, blocks
15:54 ShadowNinja PilzAdam: Hmmm?
15:54 rmilan a bit? i think still much diff would be, if someone walk around when bored, its not saved
15:54 ShadowNinja The TODO mentions both saving only nodes and saving only modified blocks.
15:55 PilzAdam ShadowNinja, http://dev.minetest.net/Terminology
15:55 ShadowNinja rmilan: I meant a lot.
15:55 PilzAdam there are no plans to save single nodes
15:55 * ShadowNinja knows the terminology.
15:55 rmilan i saw somewhere nodes also :D
15:56 ShadowNinja Instead of storing everything in the database, only store the changed mapblocks (or even only modified nodes?). This would save a lot of space. -- dev.minetest.net/TODO
15:56 rmilan only store the changed mapblocks (or even only modified nodes?)
15:57 rmilan from: http://dev.minetest.net/TODO#​Store_block_differences_only
15:57 rmilan hm, i was slow :DD
