rspec - Running unit tests for Puppet modules -


i add rspec unit tests puppet 4 modules. started , confirm basic functioning, first run unit tests come standard puppet modules such puppetlabs/apt.

if try running specific unit test so

cd modules/apt rspec spec/classes/apt_spec.rb

i failures, , of diagnostic output seems indicate part of puppet runtime environment (such module stdlib, defines function merge) not picked correctly:

failures:    1) apt defaults should contain file[sources.list] notifies class[apt::update]      failure/error:        { is_expected.to contain_file('sources.list').that_notifies('class[apt::update]').only_with({          :ensure  => 'file',          :path    => '/etc/apt/sources.list',          :owner   => 'root',          :group   => 'root',          :mode    => '0644',          :notify  => 'class[apt::update]',        })}       puppet::preformattederror:        evaluation error: unknown function: 'merge'. @ /home/my_user/modules/apt/spec/fixtures/modules/apt/manifests/init.pp:50:14 on node my_host

if try running unit tests so

rake spec

i error message:

rake aborted! nameerror: uninitialized constant bundler /home/my_user/modules/apt/rakefile:3:in `<top (required)>' (see full trace running task --trace)

prior these attempts have taken steps prepare runtime environment (on debian host):

 mkdir modules  cd modules  puppet module --modulepath=. install puppetlabs-apt # installs stdlib  sudo gem install rspec-puppet  sudo gem install puppet  sudo gem install puppetlabs_spec_helper  sudo apt-get install rake

my question this: how can correctly prepare runtime environment , run unit tests come puppet module puppet forge such puppetlabs/apt?

to need firstly ensure have ruby gems installed. ensure have installed bundler, means typing:

$ gem install bundler

next, assume cloned apt module, cd directory cloned in , install bundle:

$ bundle install

now, there's problem specific module you've chosen. when try run bundle install get:

could not find gem 'puppet-module-posix-default-r2.0' in of gem sources listed in gemfile or available on machine.

i not sure means @ moment, , needs raise bug.

i expected able work around using:

$ bundle install --without development system_tests

even not working commented-out groups.

next, run tests using:

$ bundle exec rake spec

that run tests. however, think puppet has broken rspec tests people outside company.

i going follow , come , update answer have figured out has happened.

i'll leave answer here since it's still documenting correct procedure.

see blog post on subject, although possibly little dated now. let me know if there's need update.

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer

jquery - Responsive Navbar with Sub Navbar -

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
