When starting the server, I get this strange error after updating to Ruby 1.9: " [BUG] cross-thread violation on rb_gc() ruby 1.8.6 (2008-08-11) [i386-mswin32] This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information. " My mongrel version is 1.1.6,...
It seems to me that the Ruby community has been freaking out a little about autoload since this famous thread, discouraging its use for thread safety reasons. Does anyone know if this is no longer an issue in Ruby 1.9.1 or 1.9.2? I've seen a bit of talk about wrapping requires in mutexes and such, but the 1.9 changelogs (or at least as...
i've installed the latest upgrades to the dev tools, and tried re-installing, and yet i still get this error: You have to install development tools first. from /Users/jian/Downloads/ruby-1.9.1-p378/lib/mkmf.rb:427:in try_compile' from /Users/jian/Downloads/ruby-1.9.1-p378/lib/mkmf.rb:473:intry_static_assert' from /Users/jian...
So I followed the railscast tutorial (http://railscasts.com/episodes/170-openid-with-authlogic) and used the old version of the plugin from Ryan's git file. I can now successfuly create/register a user using OpenID (Google), but I cannot log in with this user. When I submit the OpenID that has been registered, I get "uninitialized consta...
Is there any way to use gmail as a smtp server on rails 2.3.5/ruby 1.9.1? My smtp settings for actionmailer are options = { :address => "smtp.gmail.com", :port => 587, :domain => 'REMOVED', :user_name => 'REMOVED', :password => 'REMOVED', :authentication ...
I often want to take out a subpart from an Enumerable. The subpart is sometimes at the beginning and sometimes the end of the original Enumerable instance, and the length used to specify the subpart is sometimes that of the subpart and sometimes its complement. That gives four possibilities, but I only know how to do three of them. Is th...
According to this rubyquiz, external iterators used to be slow, but are now faster. Is this an improvement only available in YARV (the C-based implementation of ruby 1.9), or is this also available in the C-based implementation of ruby 1.8.7? Also, does enum_for rely on external iterators? ...
Hi, I start to using cassandra and I want to index my db with sphinx. I wrote ruby script which is used as xmlpipe, and I configure sphinx to use it. source xmlsrc { type = xmlpipe2 xmlpipe_command = /usr/local/bin/ruby /home/httpd/html/app/script/sphinxpipe.rb } When ...
I'm getting some string data from the web, and I suspect that it's not always what it says it is. I don't know where the problem is, and I just don't care anymore. From day one on this project I've been fighting Ruby string encoding. I really want some way to say: "Here's a string. What the hell is it?", and then use that data to get it ...
I'm making a gem for internal use. In it, I load some YAML from another directory: # in <project_root>/bin/magicwand MagicWand::Configuration::Initializer.new(...) # in <project_root>/lib/magicwand/configuration/initializer.rb root_yaml = YAML.load_file( File.expand_path("../../../../data/#{RootFileName}", __FILE__)) # in <project_r...
Let's say I have an arbitrarily deep nested Hash h: h = { :foo => { :bar => 1 }, :baz => 10, :quux => { :swozz => {:muux => 1000}, :grimel => 200 } # ... } And let's say I have a class C defined as: class C attr_accessor :dict end How do I replace all nested values in h so that they are now C instances with the dict attri...
Given an array containing other nested arrays, I want to create an array containing only the elements from the first array. For example [["1", "2"], "3", [["4"]]] should evaluate to ["1", "2", "3", "4"]. I've managed to make a method that works: @@unwrapped_array = [] def unwrap_nested_array(array) if array.respond_to?('each') ...
I am getting the following encoding error when trying to scrap web pages with hpricot in ruby 1.9: Encoding::CompatibilityError: incompatible character encodings: ASCII-8BIT and UTF-8 I can reproduce the error by doing the following: ska:~ sam$ rvm 1.9.2@hpricot ska:~ sam$ ruby -v ruby 1.9.2dev (2010-05-31 revision 28117) [x86_64-dar...
Hi, I would like to execute some methods atomicity with Ruby, according to http://en.wikipedia.org/wiki/Atomicity_(database_systems) For instance, if I have: a = 30 b = 75 I would like to be able to do something like: atomic_operation do a += 10 b -= 39 end Is there a native module in Ruby 1.9 that allow such process? If pos...
I have a Rails application running on Rails 2.3.9. It runs fine with ruby 1.8.7. I'm testing it with ruby 1.9.2-head right now. The application loads fine until I try to load a page that relies on a unicode string. Then I get the infamous encoding error: ActionView::TemplateError (incompatible character encodings: UTF-8 and ASCII-8BIT...
So ruby 1.9 is really nice in that it'll automatically require rubygems, and hence when you call require 'somegem' without first requiring rubygems it'll work, and that's generally awesome. But I have a ton of shell scripts using ruby, and they generally don't rely on rubygems. Shell tools should run instantly, and loading rubygems for ...
I have a Rails project with lots and lots of cyrillic strings in it. It worked fine on Ruby 1.8, but Ruby 1.9 recognizes all source files as US-ASCII-encoded until you provide an # encoding: utf-8 comment on top of each and every source file in the project. Obviously the files don't parse as US-ASCII. Is there a simpler way to say, li...

Currently Google SketchUp for Mac has Ruby version 1.8.5 which I find a bit outdated. I can update Ruby to 1.8.7 (OSX's version) by the following commands $ cd /Applications/Google\ SketchUp\ 7/SketchUp.app/Contents/Frameworks/Ruby.framework/Versions/Current $ ls Headers/ Resources/ Ruby $ ls Headers/ config.h defines.h inter...
There is a very noticeable difference in application initiation time between running my specs from the command line with ruby 1.9.x vs. 1.8.7. My application initiates much faster with ruby 1.8.7 than with ruby 1.9.1 or 1.9.2. The application initiation difference is approximately 18 seconds. It takes about 5 seconds for my app to ini...
