Console: value -1 is out of range [256, 32768] for core.max_slice_size

Software Siril
1

I am on latest git master, building from source on Linux Debian: 1.3.3-93-gde02a6307.

Why do I get this in the log?

value -1 is out of range [256, 32768] for core.max_slice_size

When I start Siril I get this in the console:

Indeed in config.1.3.ini I have:

[Core]
...
max_slice_size=-1

but I have not put this there.

If I erase ~/.config/siril and restart I get a new config.1.3.ini with the same max_slice_size=-1 again.

EDIT: I suppose I can fix it by assigning a value in range, but what does core.max_slice_size do?

Nothing to worry about. -1 is used as a default value for if the config hasn’t been set, but the usual sensible range is 256 to 2^16, and I overlooked that Siril would complain about -1 being outside the permitted range. I’ll fix the way it’s handled so the warning doesn’t show up, but it doesn’t affect anything at all.

Thanks, @ajeb78,

What does it configure? Is it connected to siril application->preferences in any way?

I checked here: Preferences (commands) — Siril 1.3.0 documentation, but did not find anything.

Got it. Thanks. Great.

EDIT: Aha, GraXpert deconvolution in 3.1RC1 Releases · Steffenhir/GraXpert · GitHub

EDIT2: Sorry I am confused. I have no idea if this change is related to filters → deconvolution or GraXpert → deconvolution, or both. I will let the developer comment on that. Anyway, I am glad I discovered GraXpert deconovlution as a side effect of checking this.
