no such file to load -- em/iterator

[jpsilvashy]

Maybe I'm doing something wrong here but which gem contains this library?

/Users/jpsilvashy/.rvm/gems/ruby-1.9.2-head/bundler/gems/em-mysqlplus-5ceee01679dc87691ab1affbf96f7dc8f5b251f7-master/lib/active_record/connection_adapters/em_mysqlplus_adapter.rb:1:in `require': no such file to load -- em/iterator (LoadError)

em-iterator is contained in em-synchrony, which is required in the gemfile. Hmm. You're getting this when you try to load thin?

[jpsilvashy]

Yes, when thin tries to start. Thanks again!

[jpsilvashy]

Oops, I didn't mean to close the issue.

[igrigorik]

Any modifications to the bundler file?

[jpsilvashy]

Nope that's everything as is from the repo, I'm trying to debug it now. Great work btw, I'm really excited about contributing to this.

Same problem here

Hey guys, the em/iterator is due to me using the head version of EM (as opposed to 0.12.10 which is official atm). Try adding the following require to your gemset:

gem 'eventmachine', :git => 'git://github.com/eventmachine/eventmachine.git', :require => 'eventmachine'

[aemadrid]

wouldn't it be better to change the gemset in the repo for everyone?

[igrigorik]

I did, git pull and that should do the trick. I was holding back, hoping that the new EM gem would be pushed out soon.

Thanks!

thx for the awesome work on this project.

I'm trying to work through the last code example here:
http://www.igvita.com/2010/03/22/untangling-evented-code-with-ruby-fibers/

but, i'm getting

uninitialized constant EventMachine::Synchrony::Iterator

i've tried a few variations of using :git in my Gemfile, including the suggestion above, but I'm having no luck. Any ideas?

Thanks again for the awesome work on this.

[igrigorik]

Brian, which version of EventMachine are you running? Iterators only appearead in 0.12.10, so it's a conditional require: https://github.com/igrigorik/em-synchrony/blob/master/lib/em-synchrony.rb#L15

You may need to update your Gemfile to pull eventmachine from the git repo.

[landlessness]

thx for the fast response. i've been using the latest github version of eventmachine.

the eventmachine version check looked like it should be using an if instead of an unless.

i changed it and sent you a pull request.

it's working now.
