goiardi version 0.10.0 - Taihun

“Taihun” was the Gothic word for “ten”. For whatever reason all of the surviving Germanic languages have lost that ‘h’ sound in the middle of the word “ten”, but Gothic preserved it. You can also see some of the usual Germanic sound changes in that word, where a ’d’ sound became a ’t’, and at least some ‘k’ sounds became an ‘h’ sound. Compare Latin decem (bear in mind that the ‘c’ there had a ‘k’ sound originally). You see that sound change as well with “hundred” (compare Latin centum (same thing with the ‘c’)). It also shows a lack of satemization - compare the Russian де́сять (desyat’).

I am pleased to present goiardi version 0.10.0 - Taihun. This release brings the long discussed PostgreSQL based search, along with a search bug fix and some behind-the-scenes changes that won’t impact anyone directly.


* Search architecture changed so different search backends can be used (thanks
  oker1 for your work on that).
* Postgres search is here at last! If you're using Postgres, instead of using
  the ersatz solr search, you can instead use Postgres to power your searches.
* Add a mutex for the original goiardi search - multiple simple queries
  executing simultaneously are not a problem, but multiple complex queries can 
  eat up all the RAM on the machine and cause goiardi to crash. This mitigates
  that situation.
* Be a little more forgiving with reporting protocol versions - allow
  specifying the protocol version as a query param instead of only as a
  header. This is to make showing reports with the webui a little easier.
* Bump the Chef Server version we claim to be from 11.1.6 to 11.1.7.

The Postgres search has come a long way since it went into preview. Performance with 10,000 fauxhai generated nodes is a lot more reasonable now, and it appears to be stable and behaving well. If it isn’t, of course, I’d like to hear about it. There is more detailed documentation about the new postgres search available, if you’re interested. The postgres search preview post also has useful information that’s still relevant, if you haven’t seen it yet.

For the future, once 1.0.0 is finished, I also want to make a standalone version of this search à la universe that could work with Chef Server. This would require some changes in erchef to populate the tables, though.

As mentioned in the release notes:

No matter what, whether you’re using the new postgres search or not, if you’re upgrading to this release you’ll need to rebuild your search index. If you’re using the old search, delete your index file first. Then, whether you’re using the old trie index or the new postgres based search, run knife index rebuild -y.

At last, the little issues that kept presenting themselves should all be dealt with. Development on 1.0.0, bringing orgs+RBAC to goiardi, can restart and hopefully be finished sooner rather than later.
