I want to use ark to untar some files at some path. But I am not able  
to update those files by modifying the recipe.

I am using the following recipe:

1 ark ‘app’ do  
2  
3 url '[http://192.168.2.50:8080/ubuntu/app-0.0.1.tar.gz](http://192.168.2.50:8080/ubuntu/app-0.0.1.tar.gz)’  
4 checksum  
’66a8e3b8716106cfc3436c2edfcb97fc5474b5d48f48fa96cf104c35b705dfaa’  
5  
6 # url '[http://192.168.2.50:8080/ubuntu/app-0.0.2.tar.gz](http://192.168.2.50:8080/ubuntu/app-0.0.2.tar.gz)’  
7 # checksum  
’13a88b5594ad0180e5547a7a22cdb74a0c3a4f89a45f33a28936e72f00c8fdd4’  
8  
9 action :put  
10 path '/home/koko’  
11 end

The recipe works fine the first time. app-0.0.1 is unzipped correctly  
in /home/koko

The problem is that when I delete lines 3 and 4 and uncomment lines 6  
and 7 and push the recipe to chef server, and then run chef-client on  
a node, I do not get the contents of app-0.0.2.tar.gz in  
/home/koko/app. Those files are unchanged.

Also, the app.tar.gz in cache is unchanged (it is same as app-0.0.1.tar.gz)

However, the recipes in the downloaded cookbooks is indeed changed -  
where lines 3 and 4 are deleted and lines 6 and 7 are uncommented.

So …

What am I doing wrong?

Am I using ark in a way it was not meant to OR am I not using it properly?

Please advise

Thanks

Autif

Hey autif, this is indeed a problem with how ark updates changed resources.  
The put action only checks whether the destination folder exists or not. It  
should be smarter than this. As the author of ark, I honestly don't know  
when I will get around to fixing this. I have a huge backlog of other  
public cookbook issues to fix.

Please do create a ticket at [tickets.opscode.com](http://tickets.opscode.com). that will help speed the  
process along

I will see if I can send a patch. I hope that the patch can be  
evaluated (accept or reject with comments) more quickly than it will  
take you to implement the change.

Thanks for the response.
