Logistic Chest priority

[Frightning]

So I found conflicting info on the wiki about this, but the question is fairly simple:
If I have a Requestor chest requesting (empty) Steel barrels, and have some in both an Active provider chest, Passive provider chest, and a Storage chest. Does the system prioritize which chest to take the Steel barrel from to satisfy that request by chest type, or is that ignored and only distance considered?

it depends on distance

it depends on distance

It doesn't.

https://wiki.factorio.com/index.php?tit ... priorities
Robots will take items from chests in the following order: Active provider chest --> Storage chest --> Passive provider chest.
Example: when requesting 20 barrels they will first take all they find in active provider chests, then from storage chests, and only then take them from passive provider chests.

From the table on the wiki you can also conclude that they will first satisfy all deliveries to character logistic slots, then fulfill the requester chest's deliveries and only if bots are still available will they transfer items from active providers to storage chests.

See this is the problem, earlier in the same article, in the Advanced Section, Active/Passive Provider subsection, we have:

"The priorities between active and passive Provider chest are equal" with a reference to a thread from 2014 when provider chests were newly split into active and passive versions. (Is that outdated, or is it still relevant?)

This is outdated and was changed in 0.10.2 (June 2014, one month after that thread):

• Changes:
  • Changed the prioritization of resupplying source of logistic robots. Provider has biggest priority, then storage and the last one is passive provider. This is to avoid uncontrolled filling of storage chests from the leftovers.

I like to quote the wiki when I know that the information is correct (observed/tested it myself or confirmed by other sources) but I forget that sometimes information on there is quite outdated, even on the same page. One of these days I'm going make an account there and go through the pages to correct the most obvious errors.
