Excaption while trying to use client

[anoam]

In my project I try to use client.
So I run:
client = Savon.client(wsdl: 'http://schemas.xmlsoap.org/soap/envelope/?wsdl')
client.operations

And I get:
RuntimeError: eventmachine not initialized: evma_connect_to_server

But when I have created new ampty project with same ruby, rails and savon gem - same code works fine.
It looks like there is a conflict but I can't find with what.

Hey @anoam I'm sorry that I can't be more helpful, but this exception seems incredibly specific to your own use case. You seem to be using Savon with EventMachine and also Rails, and this particular exception is stemming from EventMachine.

If you can provide some more information to help debug this issue, (maybe a larger snippet of ruby code?) I'd be willing to take a look, but I'm not sure I'd be very helpful. Good luck!

Hi, @tjarratt! Thank you for your answer. Could you prompt, what information should I post? I have just installed gem and left all settings by default. EventMachine is just used as dependency for something. For my mind it even shouldn't use EventMachine in my case, but I not sure. Full crushed code example is in original post.
In blank application it works fine, but there is same problem in blank application with same gemfile.
Just in case, here my gemfile: https://gist.github.com/anoam/603c26ed0e95132d5e14

Oh I see what's going on. It looks like HTTPI, a dependency of Savon, is using the EventMachine HTTP adapter and is failing for ... Some unknown reason?

Could you try this code:

after require 'savon'

HTTPI.adapter = :net_http

... Create client and call operation

My theory is that the EM HTTP adapter expects to be called with some particular state or at a particular time. Using another adapter should fix this particular error.

In blank application it warks fine, but there is sam problem in blank application with same gemfile.

Thanks alot!
Now it works fine.
My humble opinion is that HTTPI trys adapters from list. And net_http is after VM in this list.
I thought that I need something like #566 and it looks like that in common it was correct.
But now I see that it is not Savon problem.
Thanks again. And I'm sorry if my question was too stupid.

[tjarratt]

No apology needed. I was happy to help you with your problem! If anything, I should apologize for closing this issue so quickly and dismissing your problem. At the end of the day, the important thing is that we figured out how to fix a weird bug in some software.

FYI, I ran into this as well. Changing the HTTPI transport to net_http fixed it.
Seems unfortunate that em_http defaults to a higher priority transport than net_http even though it seems to require some preparatory setup.

[tjarratt]

I suppose it might be a good idea to lower em_http in the list.

Mostly I'm surprised to find this many people using event machine and Savon together.

This is uncommanded. My script is just a plain ruby file with require 'savon' in it.
I have eventmatchine installed on my machine, but other than that, I'm not including it or doing anything explicit with eventmachine in this script.
