• json_pure/rubygems cyclic dependencies

  - by andrewmcdonough

  I have an issue when trying to set up rvm, where gems weren't installing due to them being dependent on json_pure. I tried to install json_pure, but rubygems itself seems to depend on json_pure. I have tried removing all versions of json_pure, but rubygems still complains. $ sudo gem install json_pure /Library/Ruby/Site/1.8/rubygems.rb:777:in `report_activate_error': Could not find RubyGem json_pure (= 0) (Gem::LoadError) I have tried downloading the gem and installing it locally, but rubygems still complains about the dependency.

• json problems with making a ruby on rails application

  - by Prince Merdz

  So I'm using Bitnami to learn Ruby on Rails. I have also previously tried the manual installation for ruby and rails and was met by the same problem so I thought I should try first the easy package deal of Bitnami. Anyway my problem with json is that it causes the bundle install to fail. First the auto bundle install that rails new does fails because of an ssl error. Which is easily solved by changing the source in the gemfile which is https to http. However when I try to bundle install it does another error when it tries to install json.

• stdio's remove() not always deleting on time.

  - by Kyte

  For a particular piece of homework, I'm implementing a basic data storage system using sequential files under standard C, which cannot load more than 1 record at a time. So, the basic part is creating a new file where the results of whatever we do with the original records are stored. The previous file's renamed, and a new one under the working name is created. The code's compiled with MinGW 5.1.6 on Windows 7. Problem is, this particular version of the code (I've got nearly-identical versions of this floating around my functions) doesn't always remove the old file, so the rename fails and hence the stored data gets wiped by the fopen(). FILE *archivo, *antiguo; remove("IndiceNecesidades.old"); // This randomly fails to work in time. rename("IndiceNecesidades.dat", "IndiceNecesidades.old"); // So rename() fails. antiguo = fopen("IndiceNecesidades.old", "rb"); // But apparently it still gets deleted, since this turns out null (and I never find the .old in my working folder after the program's done). archivo = fopen("IndiceNecesidades.dat", "wb"); // And here the data gets wiped. Basically, anytime the .old previously exists, there's a chance it's not removed in time for the rename() to take effect successfully. No possible name conflicts both internally and externally. The weird thing's that it's only with this particular file. Identical snippets except with the name changed to Necesidades.dat (which happen in 3 different functions) work perfectly fine. // I'm yet to see this snippet fail. FILE *antiguo, *archivo; remove("Necesidades.old"); rename("Necesidades.dat", "Necesidades.old"); antiguo = fopen("Necesidades.old", "rb"); archivo = fopen("Necesidades.dat", "wb"); Any ideas on why would this happen, and/or how can I ensure the remove() command has taken effect by the time rename() is executed? (I thought of just using a while loop to force call remove() again so long as fopen() returns a non-null pointer, but that sounds like begging for a crash due to overflowing the OS with delete requests or something.)

• Running RSpec on Google App Engine via JRuby

Thank you.

• Non-standard routes in Rails

  - by trobrock

  I currently have a routes.rb file that looks like this: map.resources :profiles do |profile| profile.resources :projects, :has_many => :tasks end And this gives me routes like this: /profiles/:profile_id/projects/:project_id/tasks This is close to what I want, but instead of the '/profiles/:profile_id/' section I want to just have a username in place of that so the route would look something like: /:profile_user/projects/:project_id/tasks How can I achieve something like this? I have looked all over and haven't found anything about how to do this, but I also might not have been searching for the right thing.

• RSpec mocking a nested model in Rails - ActionController problem

  - by emson

  Hi All I am having a problem in RSpec when my mock object is asked for a URL by the ActionController. The URL is a Mock one and not a correct resource URL. I am running RSpec 1.3.0 and Rails 2.3.5 Basically I have two models. Where a subject has many notes. class Subject < ActiveRecord::Base validates_presence_of :title has_many :notes end class Note < ActiveRecord::Base validates_presence_of :title belongs_to :subject end My routes.rb file nests these two resources as such: ActionController::Routing::Routes.draw do |map| map.resources :subjects, :has_many => :notes end The NotesController.rb file looks like this: class NotesController < ApplicationController # POST /notes # POST /notes.xml def create @subject = Subject.find(params[:subject_id]) @note = @subject.notes.create!(params[:note]) respond_to do |format| format.html { redirect_to(@subject) } end end end Finally this is my RSpec spec which should simply post my mocked objects to the NotesController and be executed... which it does: it "should create note and redirect to subject without javascript" do # usual rails controller test setup here subject = mock(Subject) Subject.stub(:find).and_return(subject) notes_proxy = mock('association proxy', { "create!" => Note.new }) subject.stub(:notes).and_return(notes_proxy) post :create, :subject_id => subject, :note => { :title => 'note title', :body => 'note body' } end The problem is that when the RSpec post method is called. The NotesController correctly handles the Mock Subject object, and create! the new Note object. However when the NoteController#Create method tries to redirect_to I get the following error: NoMethodError in 'NotesController should create note and redirect to subject without javascript' undefined method `spec_mocks_mock_url' for #<NotesController:0x1034495b8> Now this is caused by a bit of Rails trickery that passes an ActiveRecord object (@subject, in our case, which isn't ActiveRecord but a Mock object), eventually to url_for who passes all the options to the Rails' Routing, which then determines the URL. My question is how can I mock Subject so that the correct options are passed so that I my test passes. I've tried passing in :controller = 'subjects' options but no joy. Is there some other way of doing this? Thanks...

  Ruby Enterprise Edition fails to compile from sources with GCC 4.5, but sucessfully compiles with 4.3.3. Actually, not sure if it's about GCC, but, in fact, i686 Arch linux system with laest updates won't compile RE. Compilation fails with the message: mkdir -p .ext/common make PRELIBS='-Wl,-rpath,/opt/ruby-enterprise-1.8.7-2010.01/lib -L/opt/ruby-enterprise-1.8.7-2010.01/lib -ltcmalloc_minimal ' ./lib/fileutils.rb:1215: [BUG] Segmentation fault ruby 1.8.7 (2009-12-24 patchlevel 248) [i686-linux], MBARI 0x8770, Ruby Enterprise Edition 2010.01 make: *** [.rbconfig.time] Aborted Are there any solutions excepting GCC downgrade?
