zypper log and TestCase

This is still happening after upgrading from factory ( using smart ).

For extra measure did:

rpm -e libzypp --nodeps
rpm -e zypper --nodeps

find / -name *zypp* and remove residue left behind by zypper,mainly

/var/lib/zypp
/var/tmp

removed all non-suse repositories from /etc/zypp/repos.d

rm /var/lib/rpm/__db.000 
rpm --rebuilddb

reinstall libzypp, zypper from factory

zypper-0.10.4-2
libzypp-4.4.2-2

zypper ref

zypper logs and testcase

After upgrading to latest factory this only happens when alpha2 DVD is in place. When issuing zypper dup with alpha2 DVD removed the following happens:

zypper dup

  java-1_6_0-sun-plugin 


Overall download size: 24.5 M. After the operation, additional 74.2 M will be used.
Continue? [YES/no]: 

the upgrade suggestion for liboil is correct, as I still keep that at alpha2 rev. Why java-1_5_0 should be forced on me, and java-1_6_0-sun-plugin 
removed remains mysterious.

As soon as I provide the alpha2 DVD when asked for it, the massive downgrade is suggested as above.

Now at 

libzypp-4.4.3-3
zypper-0.10.4-2

satsolver-tools-0.0.22-4

This really seems to depend on the presence of a DVD repository. If DVD is disabled it seems to behave normal. As far as I am concerned zypper should honor the most recent repository of those available for dup, not simply DVD if its there.

This still seems to be the problem with the solver telling zypper to _reinstall_ the package. You would get "the following packages will be reinstalled" for these in the new zypper. This has to be fixed in the solver.

e.g.:
2008-03-17 19:28:35 <0> workstation6l(19309) [zypper] zypper-misc.cc(summary):837 <install>   (40)ImageMagick-6.3.7.2-35.i586(openSuSE-11.0-factory)

comment #6 is correct.
Could you please try the update with the newest versions ?
If the error still exists please generate a testcase and attach it to bugzilla.
Thanks.

Trying to zypper dup with the alpha3 DVD in place ( and source enabled ) now does not offer the batch downgrade but properly offers to upgrade from factory.

Still there are some peculiarities left, which might be a bug in their own right or packaging issues:

Apart from the majority of packages being upgraded zypper wants to downgrade:

The following packages are going to be downgraded:
  libtheora0 xine-browser-plugin a52dec libffmpeg0 satsolver-tools libbeagle1 
gtk-sharp2 glib-sharp2 glade-sharp2 gdm 

No option given.

Also, again, java-1_5_0 is going to be installed in addition to java-1_6_0 as well as the java-1_5_0-sun-plugin installed and the java-1_6_0-sun-plugin removed.

The following NEW packages are going to be installed:
  java-1_5_0-sun-plugin java-1_5_0-sun release-notes-openSUSE perl-XML-Simple 
mozilla-xulrunner190 liblua5_1 libgssglue1 libMagickWand1 libMagickCore1 
libMagick++1 gimp-branding-upstream 


The following packages are going to be REMOVED:
  release-notes lua-libs libMagick++10 java-1_6_0-sun-plugin 

This also has no choice.

what options would you propose here and above?

Well, if possible, something like:

Solution1 

keep packages in question

Solution2

proceed as suggested

then there needed to be a choice too for the case of

The following NEW packages are going to be installed:
  java-1_5_0-sun-plugin java-1_5_0-sun 

I hope zypper doesn't run in "forceResolve" mode. "forceResolve" should *never* be the default, it should only be true if requested on the command line.

It does and i strongly don't agree that it should not as it is very annoying to get dependency problem prompt for things as obvious as zypper rm vim-base needing to remove also vim-data vim and gvim:

---->>>----
$ src/zypper rm --force-resolution off vim-base
Reading installed packages...

Problem: vim-data-7.1-59.x86_64 requires vim-base = 7.1, but this requirement cannot be provided
  deleted providers: vim-base-7.1-59.x86_64[@System]
uninstallable providers: vim-base-7.1-105.i586[factory]
                   vim-base-7.1-105.x86_64[factory]
 Solution 1: Following actions will be done:
  deinstallation of vim-data-7.1-59.x86_64
  deinstallation of vim-7.1-104.x86_64
  deinstallation of gvim-7.1-103.x86_64
 Solution 2: keep vim-base

Choose from above solutions by number or cancel [1/2/C]:
----<<<----

instead of:

---->>>----
$ src/zypper rm vim-base
Reading installed packages...

The following packages are going to be REMOVED:
  vim-data vim-base vim gvim


After the operation, 22.4 M will be freed.
Continue? [YES/no]: n
----<<<----

This is normal install/remove/update... i don't know whether dist-upgrade would be better-off with force-resolution disabled by default (?).

On executing zypper dup continuing from comment #8

zypper exits with:

rerunning zypper dup then suggests a mess of downgrading, upgrading etc. see attached terminal output.

BTW, looking at the dist-upgrade code, zypper does not use setForceResolve() at
all, so the libzypp default is used.

Maybe you needed a refresh. Thanx for the log, i'll try to provide more helpful
error message/hint.

> attached terminal output.

I guess this is because of the refresh that took place when you started 'dup'
again? Of course the 'downgrading' (read re-installing) is still this very bug.

Regarding comment #15: you have a case when there is just one simple request to the solver, as in 'zypper rm vim', but it makes no sense for more complicated stuff. Maybe not even if you want to install/erase two packages.

Regarding comment #19: is there a hint in the logfile whether forceResolve is on or off for "zypper dup"?

comment #19
Jano while a upgrade call you are calling the SAT-solver twice. The first run
is without forceResolve the second one is with:

Calling it twice is actually what I would propose. First call without force, then check if the problem is trivial, if yes, print problem info and run it with forceResolve.

Oh yes, i overlooked it, sorry. The first run is apparently the doUpgrade(opt_stats) call. The second one is the resolve() call as i thought doUpgrade just marks solvables for installation/removal and that resolve() is still needed. So this is not true?

I disabled force-resolution for dist-upgrade. Should i disable it also for 'zypper update'?

Was this the cause of this bug or is there still a solver issue?

Yes, but how to check if the problem is trivial? Simply by the number of solve problems or something else? Also flooding the output with the problem info in cases like in comment #15 would probably not do any good.

comment #25
Use forceResolve for a "single action" e.G. install foo only.
"zypper update" is not a single action.

The rest should be dependency problems only which hopefully has nothing to
do with zypper/libzypp

ok done in svn, to be in zypper 0.10.5. I also fixed generating of the solver test case to set force resolve _before_ generating.

Schubi, i still need an answer to the rest of the questions in comment #25 :O)

Ähm, I think that I have already given all answers. 
What is still open ?

1) Was this the cause of this bug or is there still a solver issue? (meaning the solver telling to reinstall packages).

2) is Resolver::resolve() needed after Resolver::doUpgrade()? Or should i just call commit right after the the doUpgrade()?

Aah, OK
1) Should be fixed. The reporter should retry it.
2) Resolver::doUpgrade() is enough.

I have seen the changes in zypper ;-)
