'list available foo-ver-rel' shows old packages. none

Description Jan Stancek 2012-01-31 14:11:08 UTC 
Description of problem:
I added (RHEL7 alpha) kernel repo to fresh Fedora16 installation. 
"yum list available" behaviour is not consistent when using pipes, redirecting to file or using --color=never.

1. yum --noplugins list available kernel-3.1.4-0.2.el7.x86_64
OK -> I see kernel package listed

2. yum --noplugins list available kernel-3.1.4-0.2.el7.x86_64 | cat
Error: No matching Packages to list
PROBLEM -> No packages

3. yum --noplugins list available kernel-3.1.4-0.2.el7.x86_64 > /tmp/1.txt
Error: No matching Packages to list
PROBLEM -> No package listed in file

4. yum --noplugins list available kernel-3.1.4-0.2.el7.x86_64 > /dev/tty
OK -> I see kernel package listed

5. yum --noplugins --color=auto list available kernel-3.1.4-0.2.el7.x86_64
OK -> I see kernel package listed

6. yum --noplugins --color=never list available kernel-3.1.4-0.2.el7.x86_64
Error: No matching Packages to list
PROBLEM -> Kernel package not listed

Version-Release number of selected component (if applicable):
yum-3.4.3-7.fc16.noarch

How reproducible:
100%

Steps to Reproduce:
1. add RHEL7 alpha kernel repo
2. yum --noplugins list available kernel-3.1.4-0.2.el7.x86_64 | cat
3. yum --noplugins --color=never list available kernel-3.1.4-0.2.el7.x86_64
  
Actual results:
kernel package is not listed

Expected results:
kernel package listed

Confirmed.  There's a problem in doPackageLists(), and it's also in the current HEAD.  Depending on the availability of highlighting, 'yum list available' takes two different code paths, with slightly different rules for what's shown as 'available'.  The one with 'pkgnarrow=all' does not work correctly when the pattern includes package version.

The code tries to avoid printing packages as 'Available' when the package is already installed (this works), or a newer version is installed.  We could probably fix this.

'list available foo-ver-rel' shows old packages.
Comment 4 James Antill 2012-02-01 16:18:40 UTC 
 To explain more, this happens when you "yum list available pkg-<old-version>" ... when nothing matches <old-version> in the rpmdb.

This package has changed ownership in the Fedora Package Database.  Reassigning to the new owner of this component.
