Description David Jaša 2011-12-22 15:14:10 UTC

Description of problem:
SSIA. 'yum update' does not have this problem, unreachable repos with skip_if_unavailable=1 are skipped

Version-Release number of selected component (if applicable):
yum-3.2.29-22.el6.noarch

How reproducible:
always

Steps to Reproduce:
1. set up a repo:
[test]
name=test
baseurl=<url that is valid but returns 404>
enabled=1
skip_if_unavailable=1
2. run yum --disablerepo='*' --enablerepo test makecache
3.
  
Actual results:
yum exits complaining that it can not download info for test repo:
$BASEURL: [Errno 14] PYCURL ERROR 22 - "The requested URL returned error: 404"
Trying other mirror.
Error: Cannot retrieve repository metadata (repomd.xml) for repository: test. Please verify its path and try again

Expected results:
yum skips repo

You have enabled only one repo, and Yum did skip that.  'skip_if_unavailable=1' does not prevent Yum from printing error messages (that's intended).

Could you try '--enablerepo test --enablerepo other' too?  This works upstream, but I don't have RHEL6 at hands.  Thanks!

This exactly does not work in RHEL:

# yum makecache ; echo $?
Loaded plugins: auto-update-debuginfo, refresh-packagekit, rhnplugin
[other repo metadata fetched]     
<repo_URL>: [Errno 14] PYCURL ERROR 22 - "The requested URL returned error: 404"
Trying other mirror.
Error: Cannot retrieve repository metadata (repomd.xml) for repository: <repo>. Please verify its path and try again
1

yum should ignore the error and keep going through the rest of the repos, it exits with 1 instead.

The bug is not fixed in yum-3.2.29-27.el6.noarch

yum crashes already at

    def doCommand(self, base, basecmd, extcmds):
            ...
            ...
            for repo in base.repos.listEnabled():

Just want to make sure whether it is OK for yum makecache to exit with 0 when the skip_if_unavailable repo is not available. From my point of view it is fine since the repo is expected to be unavailable sometimes, therefore I don't see a reason why yum should fail. Please confirm.

Comment 11 James Antill 2012-04-16 15:48:37 UTC

Yeh, seems fine  to me ... you told it to skip on errors, and it skipped. Success.
