[Bug 275484] New: zypp unable to handle some dependencies properly ?
https://bugzilla.novell.com/show_bug.cgi?id=275484 Summary: zypp unable to handle some dependencies properly ? Product: openSUSE 10.3 Version: Alpha 4 Platform: Other OS/Version: Other Status: NEW Severity: Major Priority: P5 - None Component: libzypp AssignedTo: kkaempf@novell.com ReportedBy: judas_iscariote@shorewall.net QAContact: kkaempf@novell.com CC: dmacvicar@novell.com Hi.. Well this is the story. PHP5 requires the "meta package" "smtp_daemon" which is provided by 1. exim 2. postfix 3. sendmail zypp seems to have IMHO the wrong behaviuor, and it ends **automatically** prefering exim wihtout any kind "dialog" asking the user what to install ( it happends with yast and zypper) ------------------- reproduce steps ---------------------------------------- 1 . Install a minimal "text mode" alpha 4 2. **after** the installation has finished, add a factory network installation source install the php5-fastcgi package. -------------------- actual result ------------------------------------------ both zypper and yast automatically select "exim" as the prefered package. ------------------ expected results ------------------------------------- A. the best case scenario - A popup window in yast or a dialog in zypper asking the user what to install, using postfix as the pre-selected alternative. B. worst case scenario: - pakcage manager automagically selects (or "Prefer") "postfix" and keep going. ------------------ additional info ---------------- in this case Php5 should not "hard require" postfix, as it only needs a sendmail compatible binary, which is provided by any of the 3 mentioned packages. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

So this is no bug. I do understand that some users have sufficient knowledge to take some solver decisions themselves. But how many popups are you willing to answer ? I'd like to ask others for their opinion, lets discuss this on opensuse-factory (after my 3-week vacation) -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

so, blindly prefering exim when the distribution reccommended and supported MTA is postfix is not a bug ? @_@

Klaus: I undestand your rationale, however this is not quite the expected behaviuor.. I. how YUM handles this case.. ? R: it install exim. :( 2. how does smart handle this ? R: it attempts to install postfix heh. :-) as you can see different package managers handle it different.. probably apt4rpm will do a different thing.. if for whatever reason the expected behaviuor ( having a dialog to choose what to install) is not possible.. I guess postfix should be prefered always right ? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

The hint should be given by the patterns pre-selected during installation. As you dont install an mta during installation (you do a minimal text-mode install), this hint is lost. If there is no hint, the resolver currently selects the smallest package. Later versions of zypp should get a more sophisticated 'rating' mechanism. See 'policies' in http://en.opensuse.org/Libzypp_NG#Proposed_Solutions -> WONTFIX / resp.

To be discussed on zypp-devel
ok , Im subscribed ;) but in short what I really expect is: a) in any kind of automated mode where user interaction is out of the question, then a "hint" telling what to prefer is the way to go. b) in interactive mode I expect a "have choice for smtp_daemon : postfix exim sendmail" no black magic involved ;) -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
