Lensfun version in package is outdated

[Torsten Bronger]

Lensfun 0.3.0 and 0.3.1 brought major improvements with them, in particular the possibility to update the lens database without re-installing Lensfun or updating the package. This is very often requested by users. Besides, the lens database has grown heavily over the last two releases, with more than 200 new lenses. Therefore, I think it is senseful to put some effort in updating the package to v0.3.1.

The old Python-based build system was removed from Lensfun. If the package used it, this would make non-trivial changes necessary.

Moreover, there are some scripts included now that are supposed to go into /usr/bin, so probably, a new package lensfun-utils or lensfun-tools becomes necessary, depending on your packaging guidelines.

I'm a dev of Lensfun and willing to help with that. I have only little -- albeit not none -- experience with Ubuntu packaging.

Note that 0.3 also breaks ABI compatibility without a soname bump. This causes issues such as this:

I found a Debian bug report where someone has patch for packaging version 0.3.0.

Status changed to 'Confirmed' because the bug affects multiple users.

Yes, unfortunately we missed that 0.3.0 breaks the ABI. We are currently trying to fix this or we will properly version the library in a new release. Please wait with packaging until we have released the new version which will hopefully appear in june.

[seebk (seebk)]

The current head of the lensfun code base is ready for a new release and we hopefully fixed all problems with the ABI compatibility. However, we have no experience with packaging and it would be great if someone could give us feedback if lensfun can be packaged properly in the current state.

The problem is that it would require 3 packages now for the upcoming version 0.3.2:

liblensfun1
liblensfun-data1
liblensfun-tools

liblensfun-tools is independent of the lensfun version. However, the database format has changed recently and has its own version number.. So actually the name of the database package has to be liblensfun-data1 as it is version 1. We are not sure if this is "allowed" as a debian package name....

Any experienced packager here who can assist us in the preparation of the upcoming release?

FWIW, there has been an (aborted) Debian packaging attempt at https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=791388.

[Torsten Bronger (bronger)]

Lensfun just released a new version 0.3.2. Changes in the build system should make Debian packaging very easy.

Status changed to 'Confirmed' because the bug affects multiple users.

From what I gather a new version is being packaged for Debian.
Does that mean Ubuntu will receive an updated version as well?

[Flames_in_Paradise (ellisistfroh-deactivatedaccount)]

@ Geert: U can watch Debian PTS¹ on this package. Though the package is in "experimental" (a.k.a. Squezze) now - given an certain period of testing in order to avoid incorporating bugs (thats the common procerede) it will make its way into "unstable -> testing"

Given the fact that any package receiving a higher version-no.² in the current development-release² it will automatically be merged until the Debian-freeze timeline.
