[2.1.11] Blueprints of storage chests contain new unnecessary data import_from when comparing with 2.0.77

[mbdevpl]

What did you do?

I made a blueprint of a storage chest that has the storage filter set, and exported such blueprint to a string, then I decode the string to JSON to see what it contains.

What happened?

I see the storage chest's filter contains the import_from entry that is related to space requests (set to default value for that item).

What did you expect to happen instead? It might be obvious to you, but do it anyway!

Since I don't think there's anything that changed related to storage chests between 2.0 and 2.1, I expected to see it doesn't contain such entry, which was the case in 2.0.77.

In both 2.1.11 and 2.0.77 such chest looks as follows (showing filtered item with count 1):

Does it happen always, once, or sometimes?

Always, reproduction steps:

1. open Factorio Space Age version 2.1.11 (or 2.0.77) - in my case Linux build downloaded from the Factorio website
2. start a new game (default settings)
3. press ~ to open console
4. type /editor twice in console to enter editor
5. give yourself a storage chest
6. place it in the world
7. exit the editor
8. pick wood you start the game with, set the chest filter to wood
9. make blueprint of just the chest
10. export it to exchange string
11. decode and inspect the JSON data

P.S.

The storage chest filter also probably doesn't need to store the count (usually set to 1) and I'm not sure how but I found that in some of my blueprints the storage chest filter count is set to 0 instead of the usual 1 (which you can see in-game, as the Barrel filter doesn't have a number in the screenshot below), but I'm not sure how to create those or from which Factorio version these are.

Thanks for the report. Given that this has no in game effects and it is based on implementation details, i am going to classify this as Not a bug.

Implementation detail is that storage chests keep the storage filter as part of logistic section, even if the gui does not show logistic sections. Given that 2.1 includes an "import from any" feature, value of import_from can no longer be optimized for blueprint string because lack of value has different meaning than default value and as such whenever logistic sections are saved, import_from value for item filters is always saved.

I see! I agree, an intended difference is definitely not a bug, thank you for clarifying! I didn't realise that the logistic filter field in storage chests uses same logic as in other places, but it makes perfect sense for it to do so.
