[chef] Re: Dependency problems with recent gem releases of ohai and mixlib-shellout

[Serdar Sutay < >]

Ohai chefs, 

Yesterday we have a postmortem about the recent issues we had with ohai / mixlib-shellout releases. 

You can read about the details of the issues in this blog post: https://www.chef.io/blog/2014/12/02/postmortem-ohai-mixlib-shellout-gem-release-issues/

Issues are now mitigated with yanking ohai 7.6.0 version and releasing an ohai 0.8.1 (needed to skip 0.8.0 due to a tagging issue).

In our postmortem we've decided to implement these corrective actions: 

* Fix all the omnibus projects that are pointing to `mixlib-shellout 1.6.0` [Done]

  * opscode-omnibus - Fixed. Thanks @marcparadise.

  * omnibus-chef - https://github.com/opscode/omnibus-chef/pull/305

  * opscode-analytics - https://github.com/opscode/omnibus-analytics/pull/156

  * omnibus-delivery - no issue

  * omnibus-webui - https://github.com/opscode/omnibus-webui/pull/55

  * omnibus-supermarket - no issue

  * omnibus-pushy - no issue

  * omnibus-reporting - no issue

  * omnibus-sync - no issue

  * omnibus-ha - no issue

  * omnibus-harmony - no issue

  * omnibus-chef-server - no issue

* Yank the `ohai 7.6.0` gem from rubygems. [Done]

* Release ohai with a new major version bump. [Done]

* Bump the version of rubygems and bundler that ships in Chef Client 11 omnibus packages in order not to ship a buggy version of these tools. (https://github.com/opscode/oc_post_mortems/issues/73)

* Policy to bump the versions of the tools in Chef packages during minor releases as long as they are not breaking backwards compat [Done]

* Update the mailing list with the corrective actions on the issue. (https://github.com/opscode/oc_post_mortems/issues/74)

Thanks again for everyone's patience with us during the disruption we've caused during latest releases.

Hey chefs,

In order to prep for upcoming Chef Client 12 release, yesterday we've released ohai 7.6.0, mixlib-shellout 1.6.1 & mixlib-shellout 2.0.0. 

Unfortunately with these releases we have broken gem installation of chef (gem install chef) for version 11.16.4 due to dependency conflicts. Huge thanks goes to migurski [https://github.com/migurski] for bringing this up to our attention.

You can read more about the details of the issue and our plan on resolving it at https://github.com/opscode/chef/issues/2517. In order to prevent further spreading of the issue we will yank ohai 7.6.0 release soon.

After mitigating the issue we'll do a blog post with more details and have a postmortem in order to ensure the problem doesn't happen again. 

Sorry for the inconvenience we've caused and thanks for your patience while this gets sorted out.
