[0.17.62] Desync Report Character variation

[Muppet9010]

When I look at a desync report I've noticed that for a non broken mod there is variation in the reference and desynced script.dat files. It looks to be a serialisation variation that I don't recall ever noticing in older Factorio versions (early 0.17 or maybe 0.16).
Not sure if it matters but the server is linux and the client is windows. Although I'd assume the serialisation is done entirely client side.

Its a table of tables (burners of burner_details) and in reference there is no key for the burners table, but in desync there is a key given.

reference (mp-save-02) has:

Code: Select all

mod-Burner-Leechÿ1™ do local _={burners={{entity={magic="802384732948701238470123",type=0x0p+0,entitytarget=0xd.6p+4},position={y=-0x3.68p+4,x=-0x3.88p+4},force={magic="802384732948701238470123",type=0x5p+0,forceid=0x1p+0},surface={magic="802384732948701238470123",type=0x1.9p+4,surfaceindex=0x1p+0}}}

desync has:

Code: Select all

mod-Burner-Leechÿu¶ do local _={burners={[0x1p+0]={entity={magic="802384732948701238470123",type=0x0p+0,entitytarget=0xd.6p+4},position={y=-0x3.68p+4,x=-0x3.88p+4},force={magic="802384732948701238470123",type=0x5p+0,forceid=0x1p+0},surface={magic="802384732948701238470123",type=0x1.9p+4,surfaceindex=0x1p+0}}}

in "desync" the extra serialisation is: {burners={[0x1p+0]={

Is there a question you are looking to be answered?

Also when checking for a desync, only the contents of `level-heuristic` is compared,
It is best to search for any root cause by checking the diff of level heuristic first

[Muppet9010]

is the variation in serialisation expected/accepted or is it a bug?

[Rseding91]

The script variations are almost always triggered by variations in the game logic. They never trigger the desync system so it's always in level-heuristic as Klonan says.
