Yes, the version declaration for versions <2 isn't required (and I don't bother 
adding it to the files I'm working with up to this point); my suggestion in the 
earlier thread to change it to "1" was simply because that's what the official 
backported files do. It doesn't hurt. :)

[darktable-user] Workaround: Pentax KP, liblensfun-data 0.2.8-3pmjdebruijn2~xenial

[Аl Воgnеr]

Maybe someone is interested how to use the Pentax KP with Ubuntu 16.04.
I discussed this with Thorsten Bronger from lensfun privately and
finally this worked in an own file.



Ricoh Imaging Company, Ltd.
Pentax
Pentax KP
KP
Pentax KAF2
1.534



~/.local/share/lensfun$ ls -1
compact-canon.xml
compact-panasonic.xml
compact-pentax.xml
compact-ricoh.xml
compact-sony.xml
kp.xml
mil-canon.xml
mil-pentax.xml
mil-sony.xml
mil-tamron.xml
slr-canon.xml
slr-pentax.xml
slr-ricoh.xml
slr-sigma.xml
slr-sony.xml
slr-tamron.xml

I have some files from git in ~/.local/share/lensfun , but it didn't
help to add the part from  to  in slr-pentax.xml.

So I tried an own file kp.xml with . Note there is no
version included!

Until now I didn't notice a problem.

Thanks, I'm well aware of that page, as I create, add, and remove database 
files from my local lensfun db in the process of creating lens profiles from 
user submitted files via the github repository. Not only does that page not 
address my question about version differences between 1 and 2, but neither does 
the more specifically-intended-to page linked from it:

 http://lensfun.sourceforge.net/manual/db_versions.html

Hence my question, but it should have been posted at the lensfun list, not 
here. Sorry, disregard.

This is simply the observable difference between the version 1 files as 
provided in bundles or via lensfun-update-data, and the files as they are 
currently in the master branch. It is the difference between the file being 
loaded by darktable or not, as empirically experienced by me during the course 
of juggling many of these files.

The database files are *intended* to be user creatable, and are not library 
internals. The reason is the one stated above, and it's a very good reason. :)

You might want to have a look here:

darktable-cmstest is inherently useless on a Mac.

What exactly are the differences to watch out for? I seem to remember digging 
into this before, but diffing some files from the backport and master didn't 
turn anything up.

You do realize that changing version like that is not exactly
guaranteed to work, right?
There was a fresh db dump for version_1, maybe it is still good:
http://lensfun.sourceforge.net/db/version_1.tar.bz2
