Description Corey Welton 2009-11-12 17:12:44 UTC

Description of problem:


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


How reproducible:


Steps to Reproduce:
1.  Create/sync/associate Content Provider, Repo, etc.
2.  Associate platform with above.
3.  in $Platform > Inventory > Connection, enable internal yum server; Look in /etc/yum.repos.d to assure rhq.repo has been created and that the data there matches the info $Platform > Inventory > Connectio
4. `yum list` 

Actual results:

[root@core-01 yum.repos.d]# yum list
Loaded plugins: refresh-packagekit
http://localhost:9080/yum/repodata/repomd.xml: [Errno 7] HTTP Exception (BadStatusLine): 
Trying other mirror.
Error: Cannot retrieve repository metadata (repomd.xml) for repository: rhq. Please verify its path and try again
[root@core-01 yum.repos.d]# telnet localhost:9080


Expected results:

Repo metadata should be getting populated but doesn't seem to be.

Additional info:

Note the port is open:

[root@core-01 yum.repos.d]# telnet localhost 9080

Looking at the agent logs, this is the exception I'm seeing.

Comment 2 John Matthews 2009-11-18 02:35:53 UTC

First problem identified was that we were not saving the 'metadata' to the DB.
For 'metadata' I'm talking about a GZipped XML String representing a <package> element which primary.xml (yum) uses.

RHQ will look in the DB and grab a 'metadata' value for each package, it then throws them together to create the primary.xml.

We addressed a change to the RHN plugin to translate it's data to the <package> blob and pass it gzipped into the DTO object.  The data is now being persisted in the database, but it looks like more work is required.

When doing a yum repolist, I see "0" packages.

The initial problem "yum list" returning an error has been fixed, but the process as a whole needs more work.


The 2 commits done to address the metadata with RHN Plugin are here:
commit 4b618e36d53ef97c8710243ba0868312e4da71c0

    Allows RHN plugin to save 'metadata' needed by RHQ Yum operations


commit 4051ded4547cf520f08f8866c085cfce6b186b1d
Author: John Matthews <jmatthew>

    Adding 'metadata' to package store in RHQ.
    RHQ requires us to form a Package element from a primary.xml for each package
    We then need to ensure this xml string is gzipped and passed into the DTO
    so it will be preserved and later used to reconstruct a primary.xml to give to yum

This is now working with latest git pull from the "content" branch.
