Description Alexander Sashnov 2007-08-09 07:00:35 UTC

Description of problem:

up2date can't install rpm package set wich rpm can install correctly because it
have error in obsoletes detection.

Version-Release number of selected component (if applicable):

on RedHat EL3: up2date-4.4.69-20
on RedHat EL4: up2date-4.4.69-25

How reproducible:

Try to install SWsoft Plesk software with hotfixes in one up2date call.

Steps to Reproduce:
1. configure up2date for access to RHN.

2. add sources for SWsoft Plesk 8.2 packages to /etc/sysconfig/rhn/sources:

yum product-distr-rpms
http://autoinstall.plesk.com/PSA_8.2.0/dist-rpm-RedHat-el3-i386
yum thirdparty-rpms
http://autoinstall.plesk.com/PSA_8.2.0/thirdparty-rpm-RedHat-el3-i386

3. Try to install psa with psa-updates packages:
  up2date-nox --dry-run --nosig psa psa-updates
  
Actual results:

up2date reports:
There was a package dependency problem.

Expected results:

Install psa and psa-updates with all dependencies.

Additional info:

psa-updates requires psa-hotfix3-8.2.0 package.
psa-8.2.0 is obsoletes 'psa-hotfix3 < 8.2.0'

psa-8.2.0 really is not obsoletes psa-hotfix3-8.2.0 but in up2date debug log I
can see:

[Wed Aug  8 16:50:36 2007] up2date Package ['psa-hotfix3', '8.2.0',
'rhel3.build82070807.17', '', 'i586', '1000', 'product-distr-rpms',
'base/psa-hotfix3-8.2
.0-rhel3.build82070807.17.i586.rpm'] is obsoleted by ['psa', '8.2.0',
'rhel3.build82070706.15', '', 'i586', 'psa-hotfix3', '8.2.0', 2]

I found this is because error in up2dateUtils.py:parseObsoleteVersion():

-    release = "0"
+    release = ""

Because this error up2dateUtils.py:isObsoleted() returns incorrect result.

>>> import rpm
>>> rpm.labelCompare(('0', '8.2.0', 'rhel3.build82070706.15'), ('0', '8.2.0', '') )
1
>>> rpm.labelCompare(('0', '8.2.0', 'rhel3.build82070706.15'), ('0', '8.2.0', '0') )
-1
