Augeas errors arise when applying yum settings on Cent OS 6 clients #47

weijianwen · 2017-05-24T11:42:36Z

Affected Puppet, Ruby, OS and module versions/distributions

Puppet: 4.10.0
Ruby: shippe with Puppet
Distribution: Cent OS 6
Module version: 1.0.0

How to reproduce (e.g Puppet code you use)

Install puppet-yum:

# puppet module install puppet-yum

Assign yum module to all nodes in site.pp on puppetserver:

node default {
    class {yum:}

     file_line { 'yum_proxy':
       path => '/etc/yum.conf',
       line => "proxy=$proxy",
     }
}

Apply yum setting on the client node:

client# cat /dev/null > /etc/yum.conf; puppet agent --verbose --debug -t

What behaviour did you expect instead

Yum settings should be applied on to the client node.

Output log

Any additional information you'd like to impart

The same configuration works well for Cent OS 7 clients.

Hi @weijianwen, thanks for the issue. Can you provide us the error message you get?

weijianwen · 2017-05-24T11:46:18Z

@bastelfreak thank you for your quick response. I accidentally clicked the "Send" button in the middle of typing. Now more information is added. Please tell me if anything else if required.

domcleal · 2017-05-24T11:47:03Z

Can you run the agent with --debug? There should be more information for the Augeas[yum.conf_main_keepcache]` resource and others.

weijianwen · 2017-05-24T11:48:12Z

Sure. I'll replace the logs with --debug option.

weijianwen · 2017-05-24T11:51:44Z

Log updated. I am not sure what /augeas//error output refers to since I found no dirs with names like that.

domcleal · 2017-05-24T11:54:32Z

It refers to these lines in the debug output:

Debug: Augeas[yum.conf_main_exactarch](provider=augeas): /augeas/files/etc/yum.conf/error = parse_failed
Debug: Augeas[yum.conf_main_exactarch](provider=augeas): /augeas/files/etc/yum.conf/error/pos = 7
Debug: Augeas[yum.conf_main_exactarch](provider=augeas): /augeas/files/etc/yum.conf/error/line = 2
Debug: Augeas[yum.conf_main_exactarch](provider=augeas): /augeas/files/etc/yum.conf/error/char = 0
Debug: Augeas[yum.conf_main_exactarch](provider=augeas): /augeas/files/etc/yum.conf/error/lens = /opt/puppetlabs/puppet/share/augeas/lenses/dist/yum.aug:49.13-.41:
Debug: Augeas[yum.conf_main_exactarch](provider=augeas): /augeas/files/etc/yum.conf/error/message = Get did not match entire input

There's an issue with line two of the /etc/yum.conf file. Either:

It has invalid syntax, edit and fix the file manually, then re-run the module.
There's a bug in the Augeas lens for yum.conf, where it should accept something that's valid syntax and doesn't.
Augeas is out of date (1.4.0 vs 1.8.0), which is being fixed in puppet-agent (edit: and there's some bug that's been fixed.)

weijianwen · 2017-05-24T12:00:34Z

@domcleal I empty my /etc/yum.conf file then rerun it. The same issue persists. I guess I'll wait Augeas to be updated in puppet.

domcleal · 2017-05-24T12:48:36Z

What is the new error message precisely? It can't be exactly the same, as the previous error was about line two.

I didn't mean to say that just updating Augeas will fix it, just that if it were a bug fixed between those versions that it may start working.

weijianwen · 2017-05-24T14:38:42Z

I figured out why. It is my fault. I tried to modify /etc/yum.conf outside yum module without specifying operation order between them. It seems Puppet scheduled to operate /etc/yum.conf concurrently (?) which leads to such issues. Adding require solves this issue. Issue description has been updated.

WRONG configuration:

node default {
    class {yum:}

     file_line { 'yum_proxy':
       path => '/etc/yum.conf',
       line => "proxy=$proxy",
     }
}

Correct configuration:

node default {
    class {yum:}

     file_line { 'yum_proxy':
       path => '/etc/yum.conf',
       line => "proxy=$proxy",
       require => Class['yum']
     }
}

weijianwen · 2017-05-24T14:42:46Z

proxy setting in yum.conf is useful but not supported in puppet-yum yet. Any plan to add this variable? I am new to Puppet but I can help to send a PR.

domcleal · 2017-05-24T14:51:09Z

proxy and any valid yum.conf option can be set via config_options on the yum class or by using yum::config, no? (See usage: https://github.com/voxpupuli/puppet-yum#usage)

It seems Puppet scheduled to operate /etc/yum.conf concurrently (?) which leads to such issues. Adding require solves this issue.

More likely that the file can't be parsed by Augeas after being modified, perhaps the modification is creating invalid syntax or it's unable to parse whatever syntax is given. Can you attach the resulting file that fails?

weijianwen · 2017-05-24T14:59:52Z

Sure. The generated /etc/yum.conf from the failing run has the following contents in which http://proxy.mysite.com:4000 is my proxy address.

proxy=http://proxy.mysite.com:4000

domcleal · 2017-05-25T10:30:46Z

If that's the entire file then it's missing a [main] section, which is why Augeas fails to parse it.

weijianwen · 2017-05-25T11:10:34Z

Thank you, @domcleal . I'll close this issue.
