Core dump

[pschuegr]

I'm getting a core dump with a really simple request using ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-linux]. I'm sure this is not a typhoeus (edit: sorry, I meant Ethon) problem, but you may have some ideas? It started as soon as I added the httppost.

$: << './lib'
require 'ethon'

e = Ethon::Easy.new
e.http_request(
  'http://<bucket-name>.s3.amazonaws.com',
  :post,
  { 
    :body => 'hi there',
    :httppost => 'multipart/form-data',
    :params => {

    } 
  } 
)
e.perform
puts e.response_body

Hi @pschuegr,

sorry for the late response!
You're seeing this error because your are assigning the wrong thing to http_post, its supposed to be a pointer. See here for usage examples: https://github.com/typhoeus/ethon/blob/master/spec/ethon/easy/http/post_spec.rb. It is actually not easy to do it manually.
I suggest using the helper method http_request:

easy = Ethon::Easy.new
easy.http_request("www.example.com", :post, { params: { a: 1 }, body: { b: 2 } })
easy.perform

Also you are mentioning typhoeus - which is a related project but not the same: https://github.com/typhoeus/typhoeus.

Thanks @i0rek. I found the example in the spec and everything is working fine. I don't think it should be core dumping, though, or is that part of the way it binds to libcurl?

@pschuegr actually it is possible to catch that here: https://github.com/typhoeus/ethon/blob/master/lib/ethon/easy/options.rb#L284. Do you want to take a stab at it?

[pschuegr]

Sure, I can have a go. Should I just catch a general exception, or is there a more specific one?

You could validate the input and raise an ArgumentError.
