chef recipe doesn't find ohai plugin defined resource -


i want add additional resource 'version of installed openssh' ohai use in openssh maintaining recipe.

on rhel 5.11 chef 12.4.1 ohai 8.5.0 test workstation have created , tested ohai plugin

$ cat cookbooks/test/files/default/plugins/openssh.rb

ohai.plugin(:openssh)    provides "openssh"  ohai::log.debug('plugin start')    def create_objects      openssh mash.new    end     collect_data      create_objects      openssh[:version] = 'ssh -v 2>&1 |head -1| cut -d, -f1| cut -d_ -f2 '    end  end

local test of ohai plugin in irb working fine. i'm trying check resource visibility in chef recipe

$ cat test/recipes/default.rb

file "#{env['home']}/x.txt"    content 'hello world'  end  output="#{chef::jsoncompat.to_json_pretty(node.to_hash)}"  file '/tmp/node.json'    content output  end  chef::log.info("============ test cookbook ** #{openssh['version']} **")  \#chef::log.info("============ test cookbook ** #{node['kernel']} **")

by running local chef-client

$ chef-client -z -m test/recipes/default.rb

to make additional plugin visible line added config files

$grep ohai ~/.chef/*.rb ~/.chef/client.rb:ohai::config[:plugin_path] << '~/chef/cookbooks/test/files/default/plugins/'  ~/.chef/knife.rb:ohai::config[:plugin_path] << '~/chef/cookbooks/test/files/default/plugins/'

(i understand explicit )

although running printing node['kernel'] working fine , openssh version not running debug log shows:

[2016-01-27t11:48:21-08:00] debug: cookbooks detail: []  [2016-01-27t11:48:21-08:00] debug: cookbooks compile: []  [2016-01-27t11:48:21-08:00] debug: **loading recipe file xxx/cookbooks/test/recipes/default.rb**  [2016-01-27t11:48:21-08:00] debug: resources generic file resource enabled on node include: [chef::resource::file]  [2016-01-27t11:48:21-08:00] debug: resource file chef::resource::file  [2016-01-27t11:48:21-08:00] debug: resources generic file resource enabled on node include: [chef::resource::file]  [2016-01-27t11:48:21-08:00] debug: resource file chef::resource::file  [2016-01-27t11:48:21-08:00] debug: resources generic openssh resource enabled on node include: []  [2016-01-27t11:48:21-08:00] debug: **dynamic resource resolver failed resolve resource openssh**  [2016-01-27t11:48:21-08:00] debug: re-raising exception: nameerror - no resource, method, or local variable named `openssh' `chef::recipe "xxx/cookbooks/test/recipes/default.rb"'

questions:

  1. how chef out additional plugin recipe local , remote execution? how check cheffed out , ready?

  2. how notify chef-client execute ohai additional plugin local single recipe run , remote run well?

any explanations , suggestions welcomed.

alex

a few issues: first check out https://github.com/coderanger/ohai-example see how package ohai plugin in cookbook distribution. second, node attributes custom plugins still need accessed via node object: node['openssh']['version']. third, remember how execution ordering works in chef (https://coderanger.net/two-pass/) , custom attributes won't available until after plugin loaded , run.

ios - Realm over CoreData should I use NSFetchedResultController or a Dictionary? -

i'm working on app using core data , nsfetchedresultcontroller many reasons switch use realm. saw there "realm version" of nsfetchedresultcontroller on github wouldn't compatible current code using core data. the view controller displaying list of people same school, address book. list sublist of people studied in same city. so thinking make 1 unique request database retrieve list of people , filter locally list within 1 dictionary per school [string: anyobject] string section name within tableview , anyobject array of people. first solution, make nsfetchedresultcontroller each school predicate filtering location. delete actions etc.. handled delegates -> not compatible realm create dictionaries , update them each actions... -> works realm it's annoying code. any better solution? edit: i need clarify request: i'd write class inherit uitableviewcontroller. this class has list of people sorted in alphabetical order the tableview has ...
