Re: Bug#602034: jpeg8 vs jpeg-turbo



Hi Ondřej,

I have just uploaded libjpeg-turbo to Debian and it still hovers in NEW [1].

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. Also although I have an
opinion (as you might have guessed from this email) that we should try
to be aligned with other distributions and the reasoning for not going
for , I will be happy with whatever result will end-up.

In an IRC discussion in #debian-devel several weeks ago the consensus was: the RT team (represented Julien) will probably not want two libjpeg implementations in Debian. My first packaging approach aimed at having the compat mode libraries available [2] and allow the user to install them as a drop-in replacement for libjpeg8.

The IRC discussion lead to the result that the compat packages are not wanted in Debian, only the native TURBOjpeg ABI. I was asked to ping Bill Allombert about his opinion to transition from libjpeg8 fully to libjpeg8-turbo. @Bill: can you repeat your disposition here again? I guess our earlier mailing was a private mail exchange.

A. Add libjpeg-turbo to Debian archive (that's easy)

Done. Waiting in NEW. Only containing libturbojpeg.so.1

B. Add required provides/alternatives for libjpeg62-dev and
libjpeg8-dev (where API/ABI match)

A packaging example can be seen in [1]. If the packages disappears from the NEW queue, you can also obtain a libjpeg-turbo version with compat packages provided here [3].

C. Decide which package should provide default libjpeg-dev library

Last statement from Bill: libjpeg by IJG

Greets,
Mike
