either would be fine for testing purposes, but I suppose adding it to -utils
(to match the Obsoletes) would be more appropriate

Then, which way will be more appropriate? Adding Provides: libjpeg = 6b to
libjpeg-turbo or libjpeg-turbo-utils?

Hi Rex,

The situation is bit complicated, libjpeg is split into libjpeg-turbo and
libjpeg-turbo-utils now. 
5 packages will be broken after building libjpeg-turbo in koji, if we provide
libjpeg in libjpeg-turbo, then we'll break some packages silently because they
actually depend on libjpeg-turbo-utils instead of linking with libjpeg.
Providing libjpeg in libjpeg-turbo-utils can solve all broken dependecies, but
the result will be a bit strange when we type "yum install libjpeg". 
5 packages is not a large amount, also we only need to fix openjdk once,
rpmbuild already add libjpeg.so.62 dependency to openjdk automatically, we
don't need to do it again if fedora 14 revert to use libjpeg.

I'll respectfully disagree with comment #46 ( and comment #6 ) and argue that
the Provides should be included, at least temporarily while testing is
underway.

Else, it will be impossible to truly test swapping between
libjpeg/libjpeg-turbo without breaking dependencies.

Only 5 packages need fix, among those packages only openjdk need a quick fix.
For openjdk, the fix is simply removing explict depencenies on libjpeg, we
don't need another rebuild if we revert back to libjpeg.

"yum install libjpeg" will be silly if we add provides libjpeg to
libjpeg-turbo-tools. I don't want to discuss this issue again unless fedora
packaging guideline recommends to do so.

Some people are actually using rawhide distribution. You don't need to
deliberately create broken deps if it's easy to avoid that.

First create a compatible package, then fix up everything that depends on the
compatibility interface, and only after everything is fixed remove the
compatibility interface.

The libjpeg-turbo feature page states that no rebuilds are needed to switch to
libjpeg-turbo as it is a drop-in replacement. You are now suggesting to make it
non-drop-in, why would that be good? Also, the feature page says there is a
contingency plan to revert back to libjpeg if there are serious problems. Chan,
do you understand that if you quickly rebuild all packages to depend on
libjpeg-turbo directly, then it will take another rebuild to revert back to
libjpeg if it turns out libjpeg-turbo isn't working out?

Upgrade path only applies to end users, rawhide is a place which allow to have
broken denpendecies, one week is enough to treat all those broken dependencies.

As soname deps are automatically handled by rpm, I bet most of the packages
which currently have manual libjpeg Requires do that because they really need
one of the tools. That's also why it's libjpeg-turbo-tools that is Obsoleting
libjpeg package, as opposed to libjpeg-turbo having the Obsoletes.

Since the libjpeg-turbo-tools package already contains Obsoletes: libjpeg, it'd
make sense to add the Provides: libjpeg also to the same libjpeg-turbo-tools
package.

Right now -tools subpackage has:
Obsoletes: libjpeg < 6b-47

To provide a clean upgrade path it should be:
Provides: libjpeg = 6b-47
Obsoletes: libjpeg < 6b-47


(In reply to comment #32)
> Also provides libjpeg in libjpeg-turbo will violate packaging guideline.

Huh, how so? In fact, packaging guidelines [1] suggest to use the following
scheme to replace an existing package:
Provides: oldpackagename = $provEVR
Obsoletes: oldpackagename < $obsEVR

Provides what? Original libjpeg don't have a -tools subpackage, also it's easy
to fix those broken dependencies, I don't think it's a real issue for all of
us. Also provides libjpeg in libjpeg-turbo will violate packaging guideline.

Right now -tools subpackages has Obsoletes: libjpeg < 6b-47, so it'd make sense
to add the Provides also to -tools subpackage.

It will break some packages silently, some of those packages depend on libjpeg
utilities which now packages as a subpackage. Among those packages, only
java-1.6.0-openjdk should fix intermediatly.

Personally, I suggest you to change -tools subpackage to -utils subpackages for
two reasons:

yum list \*-utils and yum list \*-tools show we have much more utils
subpackages in repo;

Upstream and wikipedia call those programs as utilities, the word utility will
be more appropriate compared to tool.

See http://en.wikipedia.org/wiki/Libjpeg

Utilities
The following utility programs are available with libjpeg:

How about to ask this on -devel? I found that many core libraries in fedora
provides static libs, e.g. glibc openssl zlib libpng. 

If we don't provide -static subpackage, we need to obsolete it in the main
package.

As I wrote in the comment #23 I don't think the -static package is needed now.

I included the "example.c" documentation file in the devel subpackage and
extended description a little, it should be sufficient.

In my opinion it's long time since F7 (libjpeg-turbo will hit F14) so we can
"retest" if someone still needs the static libjpeg. I would rather see no
static libjpeg.a for now. It might be easily added in the future if someone
requests it, libjpeg-turbo project uses libtool so I will drop the
"--disable-static" configure flag in the specfile and add -static subpackage,
it's pretty simple. If we package -static libjpeg now we won't be able to
figure time when we can say "noone uses the static libjpeg.a".

If something in package A links against a static library in package B-static,
then A also needs BuildRequires: B-static. Otherwise you just can't build
against the static library if it isn't present at build time.

My repoquery queried *source* packages for such BuildRequires. Since the result
was empty, it is safe to say in current rawhide, no package uses libjpeg-static
for building.

Is that clearer now, Tom?

The static library is used by some boot packages (think boot splash screen). 
If your ambition is to replace libjpeg 6b altogether, you'd better offer a
static library.  Obsoleting it without replacing the functionality would
certainly be bogus anyway.

It works fine on such machines, I tested it on my Pentium III:

[at...@drtic ~]$ cat /proc/cpuinfo |egrep '(model|flags)'
model   : 8
model name  : Pentium III (Coppermine)
flags   : fpu vme de pse tsc msr pae mce cx8 mtrr pge mca cmov pse36
mmx fxsr sse up

libjpeg-turbo code uses the cpuid instruction and dynamically selects the best
routines (SSE2/MMX/standard FPU).

After the debacle with the F-13 GCC breakage, best bet would be to compile
libjpeg-turbo for F-12 (since F-13 does not boot on OLPC right now) and ask
around on their mailing lists for volunteers.

One would hope that the instructions to choose are dynamically picked at

An intersting question: If we enable SIMD optimazation in libjpeg-turbo, can it
work fine on pure i686 machine without sse2, e.g. OLPC?

Fixed, fetch new spec+SRPM from:

Seems I was dazzled by performance improvement on x86 & x64 and I forgot to
test SRPM on secondary archs :)

Following SRPM should be fine:
http://atkac.fedorapeople.org/libjpeg-turbo/libjpeg-turbo.spec

Mock building for libjpeg-turbo fails on ppc/ppc64, since libjpeg is a critical
path package in fedora, I think it should be fixed and build cleanly on most
secondary architectures.

Your analysis seems valid for me, I modified the obsoletes/provides as you
suggested.

New spec + SRPM:
http://atkac.fedorapeople.org/libjpeg-turbo/libjpeg-turbo.spec

If a package supersedes/replaces an existing package without being a compatible
enough replacement as defined in above, use only the Obsoletes from above. 

For packages that are not usually pulled in by using the package name as the
dependency such as library only packages (which are pulled in through library
soname depenencies), there's usually no need to add the Provides. Note however
that the -devel subpackages of lib packages are pulled in as build dependencies
using the package name, so adding the Provides is often appropriate there. 

So for libjpeg-turbo and libjpeg-turbo-tools provides are not needed. Upgrade
path is not related to provides at all.

I'm not sure if obsoletes is needed for libjpeg-turbo since the -tools
subpackage already depends on soname, you may need check it using yum.

yum install libjpeg from official repo.

Then koji-build libjpeg-turbo, download them to one directory.

Type: createrepo 

Use a repo file such as this one:
[tmp]
name=tmp
baseurl=file:///tmp/rpm
enabled=1
gpgcheck=0

Type: yum upgrade

libjpeg's license)

correctly it is needed, isn't it?

Note for the reviewer - it might look scary that libjpeg-turbo Obsoletes &
Provides libjpeg but it is actually a proposed Fedora 14 feature -
