Update drush version on puppet controlled servers to use squeeze-backports

Reported by: Nat Meysenburg Owned by: Jamie McClelland
Priority: Medium Component: Tech
Keywords: Cc:
Sensitive: no


The version of drush installed on most of our servers is the version in squeeze mainline(version 3.3). Drush has been under serious development since this version there are many improvements and bug fixes in later versons. There is a newer version in squeeze-backports (version 4.5).

Can we configure puppet to pull in this newer version from squeeze-backports it will make all of our Drupal sites easier to administer and support?

Yes, we should do this. the drush maintainer for debian (anarcat) is quite responsive and responsible about making sure the backported version is functional.

I'm going to assign this to Ross so he can make this change because i don't know how myself :) Probably, you want to adjust /etc/apt/preferences to contain a stanza like the following:

Package: drush
Pin: release n=squeeze-backports
Pin-Priority: 600

but i dunno what the canonical way to do this is in puppet.

Ross, if you could document the changes you make to make this happen, that'd help other folks take on this kind of work when similar requests come up in the future.

I'm not sure how to do this canonically in puppet either.

Here's what I did:

I created a preferences.squeeze file with dkg's proposed preferences in ./puppet/modules/mayfirst/files/apt/ and committed those changes.

What I did not do:

I did not make changes to ./puppet/modules/mayfirst/manifests/minimal.pp

  # until we upgrade the backup servers to squeeze, squeeze installations                                      
  # have to pull in lenny and install rdiff-backup, python and python-minimal                                  
  # from lenny                                                                                                 
  case $lsbdistcodename {                                                                                      
    'squeeze': {                                                                                               
      m_apt::source { "update.list":                                                                           
        content => "deb squeeze-updates main"                                 
    'lenny': {                                                                                                 
      file { "/etc/apt/preferences":                                                                           
        source => "puppet:///modules/mayfirst/apt/preferences.lenny",                                          
        ensure => present                                                                                      
      m_apt::source { "backports.list":                                                                        
        content => "deb lenny-backports main\n"                   

I'm not sure why the lenny stanza above says '/etc/apt/preferences' as the file. It seems that preferences should be written to the '/etc/apt/preferences.d/' directory? I'm not clear on how we would make that change.

It also seems like we need to include a backports.list for squeeze. I'm not 100% clear if this means adding another stanza or not.

I'm re-assigning this to jamie for further clarification and implementation.

Hi ross and dkg,

Thanks for moving this along.

The reason the lenny stanza specifies /etc/apt/preferences is because in lenny, apt didn't support a preferences.d file so we had to overwrite /etc/apt/preferences. I've ripped that stanza out because we are no longer using lenny.

Then, I created a stanza in mosh.pp to handle this preference (because we only want it for mosh servers I think). And I added a stanza in mosh.pp to include squeeze-backports (which weren't included before). Lastly, I renamed the preferences file to be: drush.squeeze.backports.pref

Here are the resulting stanzas added to mosh.pp:

	m_apt::source { "squeeze.backports.list":
    content => "deb squeeze-backports main"
	file { "/etc/apt/preferences.d/drush.squeeze.backports.pref":
		source => "puppet:///modules/mayfirst/apt/drush.squeeze.backports.pref",
		ensure => present

This has been pushed to mfpl (and tested on chavez), but not pushed to all the other mosh's yet.
