repoquery --requires --resolve does not work properly with multilib.
Last modified: 2014-01-21 18:16:53 EST
Description of problem: repoquery --requires --resolve does not give correct results.
Version-Release number of selected component (if applicable):
On an x86_64 Fedora 13 system, use repoquery to find rpms required to install postgresql.x86_64
Steps to Reproduce:
1. repoquery -R --resolve postgresql.x86_64
-bash-4.1# uname -a
Linux ti93 126.96.36.199-54.fc13.x86_64 #1 SMP Sun Sep 5 17:16:27 UTC 2010 x86_64 x86_64 x86_64 GNU/Linux
-bash-4.1# repoquery -R --resolve postgresql.x86_64
I expect it to depend on postgresq-libs.x86_64, not .i686.
-bash-4.1# repoquery -R postgresql.x86_64 | grep libpq
-bash-4.1# repoquery --whatprovides 'libpq.so.5()(64bit)'
So how does --resolve come up with the i686 library rpm instead of x86_64?
The problem is that we assume that a pkg. will only dep. on a single arch, so whichever arch. is resolved to last wins. Fixed upstream:
% repoquery -R --resolve postgresql.x86_64
...the reason "postgresql-libs-0:8.4.5-1.fc13.i686" is considered at all is because of this dep. "postgresql-libs = 8.4.5-1.fc13".
Thanks, that makes sense. But in cases where more than one rpm supplies a given capability, would it not be reasonable for repoquery to give preference to rpms whose architecture matches the architecture of the package being queried?
In other words, if I am trying to resolve the requirements of postgresql.x86_64, and certain dependencies may be satisfied by either foo.i686 or foo.x86_64, shouldn't we automatically give preference to the .x86_64 provider?
yum itself has a lot "intelligence" here, so it will never install postgresql-libs.i686 in any normal cases.
However repoquery just treats each dep. as it's own thing, and prints all the providers. This is somewhat worse in some cases, like this, but generally better overall for the things people use repoquery for.
This message is a reminder that Fedora 13 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 13. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '13'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 13's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 13 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Fedora 13 changed to end-of-life (EOL) status on 2011-06-25. Fedora 13 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
