Which translates to.. a single CVE in libjpeg-turbo since it's inception! 3) do not implement the full libjpeg8 ABI, nor the upcoming libjpeg9. This would be a relevant if some application actually used the full libjpeg8 ABI . In fact, 100% of debian works fine with libjpeg-turbo, or even the original libjpeg6b (if the would be recompiled against it again). I find the reason that IJG libjpeg8 fork is so triggerhappy to repeatedly break the API and ABI (and image format!) rather a reason to make libjpeg8 the non-default. You should not deprive debian users from high performance jpeg rendering for a few ABI features that nobody uses - or anyone is asking for. I do not believe in debian life-span, a package manager ever switch an implementation of a package. So libjpeg9 and libjpeg-turbo will have to co-live. I understand your point that libjpeg9 offers experimental feature not needed for everyone, but at least from my point of view libjpeg-turbo by only implementing portion of ITU-T T.81, ISO/IEC IS 10918-1 (namely lossy 8bits progressive sequential) is a no-go for my applications. Have a look at ITK, DCMTK and/or GDCM which provide a patched libjpeg to provide support for lossy 8 12 bits and lossless 16bits. This is a burden to maintain those side implementations. This goes without saying that JPEG commitee is now working on a full implementation of ITU 81: https://github.com/thorfdbg/libjpeg Which also has a different license, may be slower, but *at last* provide a complete implementation of JPEG. It is said to provide an ABI compatible with the original IJG implementation in the near future. So debian may have to provide three JPEG implementations This bug will be really messy to read, but I wished the team from libjpeg-turbo and whoever is running IJG found a compromise to either integrate optimization from -turbo into jpeg9, or the other way around, -turbo provides empty body function for the new API. oh well... -M -- To UNSUBSCRIBE, email to debian-wnpp-requ...@lists.debian.org with a subject of unsubscribe.

[Mathieu Malaterre] I do not believe in debian life-span, a package manager ever switch an implementation of a package. So libjpeg9 and libjpeg-turbo will have to co-live. It happens. Look at the source for 'libc6'. It used to be glibc, these days it is a fork called eglibc. Likewise the source for the 'ssh' package was once SSH by Tatu Ylonen, these days it is a fork called OpenSSH maintained by some OpenBSD hackers. -- To UNSUBSCRIBE, email to debian-wnpp-requ...@lists.debian.org with a subject of unsubscribe.

Some of them have already been answered in the backlogs of #602034 [1] and the-merged-with bug #612341 [2]. Reading through both of them is probably a good idea for all who are interested in the complete story. Esp. some statements from Guido Vollbeding [3] make me ask myself: hey, what kind of guy is that and what is the stand of the IJG in the free software ecosystem. His arguing tends to be somehow aggressive and inbalanced. One quote that shows what I mean (taken from [3]): It seems that Bill Allombert is still one of the few sane people out there, many others have apparently gone mad. I don't care for the ignorant people. @Bill: Unfortunately, I am not an expert with image processing, but most of what I have read in this thread speaks for re-thinking the current strategy of staying with libjpeg IJG. Can this be a proposal? Package libjpeg and libjpeg-turbo using an alternatives setup and thus, making both libs installable in parallel. Packagers can then build-depend on one or the other libjpeg implementations.

Bug#602034: jpeg8 vs jpeg-turbo
Hello, The KDE maintainer in Fedora started an interesting discussion some time ago in Digikam's mailing list. There was input from the very IJG: http://mail.kde.org/pipermail/digikam-devel/2013-January/066206.html It boils down to jpeg6-2 is the only important thing. Forget about jpeg8 and jpeg9, which bring incompatible changes. http://mail.kde.org/pipermail/digikam-devel/2013-January/066256.html FWIW, Arch and Gentoo also follow the policy that jpeg6-2 (and jpeg-turbo with 6-2 API/ABI) is the real deal.

Bug#602034: jpeg8 vs jpeg-turbo
Hi Bill and Debian Developers, while doing work on GD Library 2.1.0 it was discovered there's encoding incompatibility introduced by libjpeg8/9 [1]. While doing further research I have found that Fedora has switched to libjpeg-turbo[2] (for reasoning please read the referred email). Ubuntu (and Steam) is also using libjpeg-turbo as base jpeg library. SuSE has also switched to libjpeg-turbo some time ago (just had a quick chat with it's maintainer). Debian has already open ITP[3] #602034 for libjpeg-turbo, which support libjpeg62 API/ABI and also some important bits of libjpeg8. As libjpeg is one of the base libraries of the system, I think it might be a good idea to discuss this project wide.

Decide which package should provide default libjpeg-dev library Last statement from Bill: libjpeg by IJG The current IJG has nothing to do with the IJG that originally created JPEG. The last activity of original IJG was in 1998, while new IJG surfaced in 2009. Thus we actually have two forks: 1) the new IJG libjpeg, which changes API/ABI of the original libjpeg library, and adds new features to JPEG image format. However the new image format features have been rejected as not improving image quality or compression ratio[1]. The new IJG has no mailing list, VCS or any or other sign of actually being group - all apparent IJG work seems to come from a single person. The website of IJG[2] is void of details - who is in IJG? - how does it make decisions like changing the JPEG image format to add SmartScale support? There is even no place to send bug reports! 2) libjpeg-turbo remains API/ABI and binary format compatible with original libjpeg. The most significant improvements are in supporting SIMD features to make JPEG image encoding and decoding faster on modern cpu's. Libjpeg-turbo website [3] has all the signs of an healthy open source project - A SVN repo with many commiters, bug tracker, a mailing list with open discussion etc. So the Debian options is to choose a libjpeg fork that changes the jpeg image format, or one that renders images fast. At the moment the first fork is being advertized with IJG name, thus painting an image of official upstream. But it isn't - especially not now when the changes libjpeg8 added to JPEG standard have been rejected from the ISO standard.
