Hi,

Could somebody point to a document describing how the cookbook dependencies are calculated ?

I found for attributes [http://docs.opscode.com/chef\_overview\_attributes.html](http://docs.opscode.com/chef_overview_attributes.html) but not sure if apply for cookbook version constraints.

thanks!

Did you read [http://docs.opscode.com/essentials\_cookbook\_versions.html](http://docs.opscode.com/essentials_cookbook_versions.html) ?

Hi,

I was looking for a document that explains what is the merging order of the  
dependencies and who will win in the end  
Take a situation like this

Node run config  
{  
"name": "test-constraints",  
"chef\_environment": "test",  
"normal": {  
},  
"run\_list": [  
"recipe[a]"  
]  
}

$ grep depends cookbooks/a/metadata.rb  
depends "b"  
depends "tech", "= 0.3.0"

$ tail -1 cookbooks/a/recipes/default.rb  
include\_recipe "b"

$ grep depends cookbooks/b/metadata.rb  
depends "tech", "= 0.1.0"

$ tail -1 cookbooks/b/recipes/default.rb  
include\_recipe "tech"

$ grep tech environments/test.json  
"tech": "= 0.2.0"

This runs w/o problems.  
But if I change environment to = 0.1.0 will do this

[2014-02-28T00:07:36+00:00] INFO: HTTP Request Returned 412 Precondition  
Failed: {"message"=\>"Unable to solve constraints, the following solutions

"unsatisfiable\_run\_list\_item"=\>["a"], "non\_existent\_cookbooks"=\>,  
"most\_constrained\_cookbooks"=\>["(tech = 0.2.0)"]}

If I change environment to = 0.3.0

$ knife cookbook show tech

thanks!

There is no winner per se, all constraints must be satisfied. You will have to fix your dependencies for this to have a valid solution.

Hi Noah,

Thanks for your answer, as I said I was looking to find a document that  
explains  
how the decision is taken, the closest I found as a 'doc' is

I wouldn't count on that behavior. Erchef will switching back the Ruby (gecode) depsolver soon, and Berkshelf as its own based on the Solve gem ☹

Berkshelf will be switching to gecode as well. Dan has been working on  
getting gecode to compile under windows.

To those that haven't had the pleasure of solver inconsistencies this is is an improvement roughly on par with "we are replacing your Geo Metro with a Model S".

Well, a Model S that takes 10 minutes to compile every time you refuel  
it...

Hey Silviu,

FWIW, I also had problems figuring out a cookbook's full dependency list  
and sent a patch to have chef list the full dependency branch when it  
fails to find a cookbook's dependencies at runtime:  
[https://tickets.opscode.com/browse/CHEF-5065](https://tickets.opscode.com/browse/CHEF-5065)

This might help you or others.

FWIW, I also had problems figuring out a cookbook's full dependency list and sent a patch to have chef list the full dependency branch when it fails to find a cookbook's dependencies at runtime:  
[https://tickets.opscode.com/browse/CHEF-5065](https://tickets.opscode.com/browse/CHEF-5065)

This might help you or others.

Not entirely sure what you mean. If you think you've found a bug or error in Chef you can just file a ticket on [tickets.opscode.com](http://tickets.opscode.com). If you just have a question, you can email this list.
