• ruby: invalid opcode

  - by adamo

  There's a fairly complex application than runs on two VMs (on Xen). Both VMs run CentOS 6.2 with the exact same packages and configuration for every application running (minus networking which is different). SELinux is disabled on both. On machine A the application builds perfectly. On machine B when running some tests we get: ruby[2010] trap invalid opcode ip:7ff9d2944c30 sp:7fff9797e0f8 error:0 in ld-2.12.so[7ff9d2930000+20000] Digging a bit more to find out where the machines differ, machine A has: model name : Six-Core AMD Opteron(tm) Processor 2423 HE and machine B: model name : AMD Opteron(TM) Processor 6272 I've tried booting machine B with cpuid_mask_cpu=fam_10_rev_c in grub but it did not help either. So any advice as to how to deal with this, or how to approach the hosting provider so as to run this VM on another physical machine will be greatly appreciated.

• creating TAGS for Ruby and emacs

  - by hortitude

  I ran the following from my top level Ruby on Rails directory find . -name "*.rb" | etags - Then within emacs I visited that tag file. This works reasonably well to find some of the methods and most of the files, however it is having trouble finding some of the extra methods/classes that I use in my helpers directory. e.g. I have a file in my helpers dir called my_foo_helper.rb If I search my tags for that file, it finds it. However, if I try to find a tag for one of the methods within that module it doesn't find it at all. If I use Aptana or something like that it seems to be able to locate those methods. Any thoughts? Thanks!

• Installing Rails, MySQL, etc. everything goes wrong

  - by Rits

  I've been struggling with this for a few hours. Everything just stopped working and I can't get it to work anymore. I'm a noob at Ruby, Ruby on Rails and the Terminal in general. This is really frustrating me so I just try to describe my problem as detailed as possible hoping someone can give me a solution. I'm on Mac OS X Snow Leopard. I couldn't get Rails working at all just now: Could not find gem 'rails' headaches But after some tries of reinstalling it, it suddenly worked again. But now I just can't get MySQL to work, and it sometimes even breaks the Rails installation again. This is what I do: sudo gem uninstall rails sudo gem uninstall mysql sudo gem uninstall mysql2 After these commands, I check the installed gems with gem list. No MySQL gem is listed anymore, but I can still see rails (2.3.5, 2.2.2, 1.2.6) . Is this normal? Does this mean I have 3 Rails installations? It doesn't make sense to me. Anyway, then I do this: sudo gem clean Which fails completely. I get a bunch of errors like this: Attempting to uninstall fcgi-0.8.7 Unable to uninstall fcgi-0.8.7: Gem::InstallError: cannot uninstall, check gem list -d fcgi It doesn't uninstall anything. At this point, I try to install everything again. I start with: sudo gem install rails Which succeeds (I think): Successfully installed rails-3.0.3 Successfully installed builder-2.1.2 2 gems installed Installing ri documentation for rails-3.0.3... File not found: lib Then, I update RubyGems: sudo gem update --system sudo gem install rubygems-update sudo update_rubygems Then it says I have 1.3.7 installed, so it succeeded, I think. So now I proceed with installing MySQL. I already got MySQL 5.5.8 installed on my machine. I did some research about installing MySQL on Snow Leopard, and it seems I have to use this command: sudo env ARCHFLAGS="-arch x86_64" gem install mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config I get a bunch of errors like this: No definition for time_set_neg No definition for time_set_second_part No definition for time_equal No definition for error_errno At this point, I assume I got both Rails and the MySQL gem installed, so I try to start a new project. rails new user_group -d mysql It works! Rails is installed correctly. Now, I try generating a model. cd user_group rails generate model User It fails with this error: Could not find gem 'mysql2 (= 0, runtime)' in any of the gem sources listed in your Gemfile. Try running bundle install. So I try running bundle install. It installs a lot of gems. Then I try to generate my model again. I get this error: Library/Ruby/Gems/1.8/gems/mysql2-0.2.6/lib/mysql2/mysql2.bundle: dlopen(/Library/Ruby/Gems/1.8/gems/mysql2-0.2.6/lib/mysql2/mysql2.bundle, 9): Library not loaded: libmysqlclient.16.dylib (LoadError) Referenced from: /Library/Ruby/Gems/1.8/gems/mysql2-0.2.6/lib/mysql2/mysql2.bundle Reason: image not found - /Library/Ruby/Gems/1.8/gems/mysql2-0.2.6/lib/mysql2/mysql2.bundle This is as far as I can get. What should I do? And why should this be so hard...

• Rails, if instance is in a scope?

  - by Joseph Silvashy

  I using rails 3 and I can't seem to check if a given instance is in a scope, see here: p = Post.find 6 +----+----------+-------------------------+-------------------------+-------------------------+-----------+ | id | title | publish_date | created_at | updated_at | published | +----+----------+-------------------------+-------------------------+-------------------------+-----------+ | 6 | asfdfdsa | 2010-03-28 22:33:00 UTC | 2010-03-28 22:33:46 UTC | 2010-03-28 22:33:46 UTC | true | +----+----------+-------------------------+-------------------------+-------------------------+-----------+ I have a menu scope which looks like: scope :menu, where("published != ?", false).limit(4) When I run it I get: Post.menu.all +----+------------------+------------------+------------------+-------------------+-----------+ | id | title | publish_date | created_at | updated_at | published | +----+------------------+------------------+------------------+-------------------+-----------+ | 1 | Lorem ipsum | 2010-03-23 07... | 2010-03-23 07... | 2010-03-28 21:... | true | | 2 | fdasf | 2010-03-28 21... | 2010-03-28 21... | 2010-03-28 21:... | true | | 3 | Ruby’s Imple... | 2010-03-28 21... | 2010-03-28 21... | 2010-03-28 21:... | true | | 4 | dsaD | 2010-03-28 22... | 2010-03-28 22... | 2010-03-28 22:... | true | +----+------------------+------------------+------------------+-------------------+-----------+ Which is correct, but if I try to check if p is in the the menu scope using: Post.menu.exists?(p) I get true when it should be false What is the proper way to find out if a given instance of something is in a scope?

• How can I prevent default_environment variables from getting set by Capistrano's sudo action?

  - by Logan Koester

  My deploy.rb sets some environment variables to use the regular user's local Ruby rather than the system-wide one. set :default_environment, { :PATH => '/home/myapp/.rvm/bin:/home/myapp/.rvm/bin:/home/myapp/.rvm/rubies/ruby-1.9.1-p378/bin:/home/myapp/.rvm/gems/ruby-1.9.1-p378/bin:/home/myapp/.rvm/gems/ruby-1.9.1-p378%global/bin:/home/myapp/bin:/usr/bin:/opt/local/bin:/opt/local/sbin:/usr/local/bin:/usr/local/sbin:/usr/sbin:/sbin:/bin:/usr/games', :RUBY_VERSION => 'ruby-1.9.1-p378', :GEM_HOME => '/home/myapp/.rvm/gems/ruby-1.9.1-p378', :GEM_PATH => '/home/myapp/.rvm/gems/ruby-1.9.1-p378:/home/myapp/.rvm/gems/ruby-1.9.1-p378%global' } Naturally, when a task is using sudo, I would expect the system-wide ruby to be used instead. But it seems the environment variables are being set anyway, which is obviously invalid for the root user and returns an error: executing "sudo -p 'sudo password: ' /etc/init.d/god stop" servers: ["myapp.com"] [myapp.com] executing command command finished failed: "env PATH=/home/myapp/.rvm/bin:/home/myapp/.rvm/bin:/home/myapp/.rvm/rubies/ruby-1.9.1-p378/bin:/home/myapp/.rvm/gems/ruby-1.9.1-p378/bin:/home/myapp/.rvm/gems/ruby-1.9.1-p378%global/bin:/home/myapp/bin:/usr/bin:/opt/local/bin:/opt/local/sbin:/usr/local/bin:/usr/local/sbin:/usr/sbin:/sbin:/bin:/usr/games RUBY_VERSION=ruby-1.9.1-p378 GEM_HOME=/home/myapp/.rvm/gems/ruby-1.9.1-p378 GEM_PATH=/home/myapp/.rvm/gems/ruby-1.9.1-p378:/home/myapp/.rvm/gems/ruby-1.9.1-p378%global sh -c 'sudo -p '\\''sudo password: '\\'' /etc/init.d/god stop'" on myapp.com It makes no difference whether I use capistrano's sudo "system call" or the regular run "sudo system call". How can I avoid this?

• Heroku powered private restricted beta

  - by Ben Sand

  I'd like to run an app in a restricted private beta on heroku. We're changing the app regularly and haven't done a security audit. To stop anyone exploiting stuff, we'd like to lock down the whole site, so you need a password to access anything. Ideally similar to using .htaccess and .htpasswd files to lock an entire site on an Apache server. Is there a simple one shot way to do this for a heroku hosted app?

• Apache rails beta site access solution

  - by par

  I'm building an ror site and have been asked by to put a temporary access restriction on it. All that's needed is a general access restriction and common access info which can be emailed to invited beta users. The site is deployed on an apache server (on a mac) using passenger. I'm wondering what solutions there are?

• My Ruby on Rails application only works if the address contains the port

  - by True Soft

  I have a Ruby on Rails application that works ok on my notebook ( http://localhost:3000/ ) I uploaded it on my hosting server, created with CPanel X an application, the URL is http://example.com:12007/ created a rewrite from http://example.com/ to http://example.com:12007/, and started it. If I write in my browser http://example.com:12007/ or http://www.example.com:12007/ all the pages work as expected. But if I write http://example.com/ or http://www.example.com/ the first page is displayed, but without any css or images (just like it wouldn't find them). I can see all the text (even the text from my MySQL database), but with no format. And if I click on any link, I get a error page like this: Not Found The requested URL /some_controller was not found on this server. Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request. What should I do to make my website work without writing the port in the address bar? The content of my /public_html/.htaccess file is RewriteEngine on RewriteCond %{HTTP_HOST} ^example.com$ [OR] RewriteCond %{HTTP_HOST} ^www.example.com$ RewriteRule ^/?$ "http\:\/\/127\.0\.0\.1\:12007%{REQUEST_URI}" [P,QSA,L] which I guess was generated by CPanel Rewrites.

• ruby on rails configuration

  - by Themasterhimself

  Im using the following guide for getting started with rails for ubuntu 9.10. http://guides.rails.info/getting_started.html I have installed both ruby and gem. gokul@gokul-laptop:~$ ruby -v ruby 1.8.7 (2009-06-12 patchlevel 174) [i486-linux] gokul@gokul-laptop:~$ gem -v 1.3.6 gokul@gokul-laptop:~$ For rails, gokul@gokul-laptop:~$sudo gem install rails doesnt seem to give any response. so used the synaptic package manager for installing it. And it seems to have installed correctly. gokul@gokul-laptop:~$ rails Usage: /usr/bin/rails /path/to/your/app [options] Options: -r, --ruby=path Path to the Ruby binary of your choice (otherwise scripts use env, dispatchers current path). Default: /usr/bin/ruby1.8 -d, --database=name Preconfigure for selected database (options: mysql/oracle/postgresql/sqlite2/sqlite3/frontbase/ibm_db). Default: sqlite3 -D, --with-dispatchers Add CGI/FastCGI/mod_ruby dispatches code to generated application skeleton Default: false --freeze Freeze Rails in vendor/rails from the gems generating the skeleton Default: false -m, --template=path Use an application template that lives at path (can be a filesystem path or URL). Default: (none) Rails Info: -v, --version Show the Rails version number and quit. -h, --help Show this help message and quit. General Options: -p, --pretend Run but do not make any changes. -f, --force Overwrite files that already exist. -s, --skip Skip files that already exist. -q, --quiet Suppress normal output. -t, --backtrace Debugging: show backtrace on errors. -c, --svn Modify files with subversion. (Note: svn must be in path) -g, --git Modify files with git. (Note: git must be in path) Description: The 'rails' command creates a new Rails application with a default directory structure and configuration at the path you specify. Example: rails ~/Code/Ruby/weblog This generates a skeletal Rails installation in ~/Code/Ruby/weblog. See the README in the newly created application to get going. gokul@gokul-laptop:~$ app folder is created with all the proper folders.

• The best algorithm enhancing alpha-beta?

  - by Risa

  I'm studying AI. My teacher gave us source code of a chess-like game and asked us to enhance it. My exercise is to improve the alpha/beta algorithm implementing in that game. The programmer already uses transposition tables, MTD(f) with alpha/beta+memory (MTD(f) is the best algorithm I know by far). So is there any better algorithm to enhance alpha-beta search or a good way to implement MTD(f) in coding a game?

• Language Club – Battle of the Dynamic Languages

  - by Ben Griswold

  After dedicating the last eight weeks to learning Ruby, it’s time to move onto another language.  I really dig Ruby.  I really enjoy its dynamism and expressiveness and always-openness and it’s been the highlight of our coding club for me so far. But that’s just my take on the language.  I know a lot of coders who’s stomachs turn with the mere thought of Ruby.  They say it’s Ruby’s openness which has them feeling uneasy.  I’d say “write a bunch of tests and get over it,” but I figure there must be more to it than always open classes and possible method collisions. Yes, there’s something else to it alright. The folks who didn’t fall head over heals for Ruby are already in love with Python.  You might remember that Python was the first language we tackled in our coding club.  My time with Python was okay but it didn’t feel as natural to me as Ruby.  But let’s say we started with Ruby and then moved onto Python.  Would I see Python in a different light right now.  Might I even prefer Python over Ruby?  I suppose it’s possible but it’s pretty tough to test that theory – unless we visit Python for a second time. That’s right. The language club is going to focus on Python again and in my attempt to learn Python – yet again – in the open, I’ll be posting my solutions here just as I did for Ruby.  We don’t always have second chances so I going about this relearning with two primary goals in mind:  First, I’m going to use IronPython and the IronPython tools which provide a Python code editor, a file-based project system, and an interactive Python interpreter, all inside Visual Studio 2010.  As a note, the IronPython tools are now part of the main IronPython installer which is Version 2.7 Alpha 1 (not the latest stable version, 2.6.1) and I’d be crazy not to use them.  Second, I’d like to make sure I’m still learning Python without a complete MS skew so I’m going to run my code through Eclipse using the PyDev plugin as well.  Heck, I might use IDLE too. I already have this setup on my machine so it’s no big deal. Okay, that’s it for now.  I worked on the first ten Euler problems last night and the solutions will be posted shortly. Wish me luck.

• Can't install pg gem on Windows

  - by sNiCKY

  I've got 2 Ruby versions: 1.8.7 and 1.9.2 and PostgreSQL 8.3. I cant install pg gem on any of them. Getting this error: C:/Development/Ruby187/bin/ruby.exe extconf.rb checking for pg_config... yes not recorded checking for libpq-fe.h... no Can't find the 'libpq-fe.h header *** extconf.rb failed *** Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers. Check the mkmf.log file for more details. You may need configuration options. Provided configuration options: --with-opt-dir --without-opt-dir --with-opt-include --without-opt-include=${opt-dir}/include --with-opt-lib --without-opt-lib=${opt-dir}/lib --with-make-prog --without-make-prog --srcdir=. --curdir --ruby=C:/Development/Ruby187/bin/ruby --with-pg --without-pg --with-pg-config --without-pg-config --with-pg-dir --without-pg-dir --with-pg-include --without-pg-include=${pg-dir}/include --with-pg-lib --without-pg-lib=${pg-dir}/lib I know it's a common problem, but I haven't found any working solution yet... Oh, I have added C:\Program Files (x86)\PostgreSQL\8.3\bin to my PATH.

• How to verify the SSL connection when calling an URI?

  - by robertokl

  Hello, I am developing an web application that is authenticated using CAS (A single-sign-on solution: http://www.ja-sig.org/wiki/display/CAS/Home). For security reasons, I need two things to work: The communication between CAS and my application needs to be secure My application needs to accept the certification coming with CAS, so that I can guarantee that the CAS responding is the real CAS Server. This is what I got so far: uri = URI.parse("https://www.google.com/accounts") https = Net::HTTP.new(uri.host, uri.port) https.use_ssl = (uri.scheme == 'https') https.verify_mode = (OpenSSL::SSL::VERIFY_PEER) raw_res = https.start do |conn| conn.get("#{uri.path}?#{uri.query}") end This works just great in my Mac OSX. When I try to reach an insecure uri, it raises an exception, and when I try to reach a secure uri, it allow me normally, just like expected. The problem starts when I deploy my application on my Linux server. I tried in both Ubuntu and Red Hat. Independing of what uri I try to reach, it always raises me this exception: OpenSSL::SSL::SSLError: SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed from /usr/local/lib/ruby/1.8/net/http.rb:586:in `connect' from /usr/local/lib/ruby/1.8/net/http.rb:586:in `connect' from /usr/local/lib/ruby/1.8/net/http.rb:553:in `do_start' from /usr/local/lib/ruby/1.8/net/http.rb:542:in `start' from (irb):7 I think this have something to do with my installed OpenSSL package, but I can't be sure. This are my installed OpenSSL packages: openssl.x86_64 0.9.8e-12.el5 installed openssl-devel.x86_64 0.9.8e-12.el5 installed I tried using HTTParty as well, but it just ignores the SSL certificated. I hope someone can help me, either by telling me a gem that works the way I need. Thanks.

• Rails ActiveRecord::MultiparameterAssignmentErrors

  - by Neil Middleton

  I have the following code in my model: attr_accessor :expiry_date validates_presence_of :expiry_date, :on => :create, :message => "can't be blank" and the following in my view: <%= date_select :account, :expiry_date, :discard_day => true, :start_year => Time.now.year, :end_year => Time.now.year + 15, :order => [:month, :year] %> However, when I submit my form I get: ActiveRecord::MultiparameterAssignmentErrors in SignupController#create /Users/x/.rvm/gems/ruby-1.8.6-p383/gems/activerecord-2.3.5/lib/active_record/base.rb:3073:in `execute_callstack_for_multiparameter_attributes' /Users/x/.rvm/gems/ruby-1.8.6-p383/gems/activerecord-2.3.5/lib/active_record/base.rb:3028:in `assign_multiparameter_attributes' /Users/x/.rvm/gems/ruby-1.8.6-p383/gems/activerecord-2.3.5/lib/active_record/base.rb:2750:in `attributes=' /Users/x/.rvm/gems/ruby-1.8.6-p383/gems/activerecord-2.3.5/lib/active_record/base.rb:2438:in `initialize' Any ideas as to what the problem might be? I've looked at #93277 with no joy, so am kinda stuck. Adding day to the select does NOT resolve the issue. Any ideas?

• rails not recognizing project

  - by tipu

  I can create a new project using rails and I can use stuff like rails migration ... and i (correctly) get a error because the sqlite gem is missing. but when i try using rails migration ... with a project i checked out from github, it doesn't recognize that it is a rails project i get: Usage: rails new APP_PATH [options] Options: -d, [--database=DATABASE] # Preconfigure for selected database (options: mysql/oracle/postgresql/sqlite3/frontbase/ibm_db) # Default: sqlite3 -O, [--skip-active-record] # Skip Active Record files [--dev] # Setup the application with Gemfile pointing to your Rails checkout -J, [--skip-prototype] # Skip Prototype files -T, [--skip-test-unit] # Skip Test::Unit files -G, [--skip-git] # Skip Git ignores and keeps -b, [--builder=BUILDER] # Path to an application builder (can be a filesystem path or URL) [--edge] # Setup the application with Gemfile pointing to Rails repository -m, [--template=TEMPLATE] # Path to an application template (can be a filesystem path or URL) -r, [--ruby=PATH] # Path to the Ruby binary of your choice # Default: /usr/bin/ruby1.8 [--skip-gemfile] # Don't create a Gemfile and it goes on. any ideas? edit: it's probably an important detail that earlier my rails wasn't working at all. i had to cp /usr/bin/ruby to /usr/bin/local/ruby
