fix excon adapter version #202

wants to merge 1 commit into

When tried to run the tests using excon adapter, I got this error

uninitialized constant Excon::VERSION

The issue was that excon doesn't define this varible Excon::VERSION

What version of Excon do you use? I can see Excon::VERSION defined in current version 0.15.5. https://github.com/geemus/excon/blob/master/lib/excon/constants.rb#L3

:O I'm using excon "0.14.3"

sure, but for some reason doesn't works and can't upgrade excon, because I'm using fog too that depends of excon ~> 0.14. any suggestions for this case?

can you try loading irb, require excon and see it Excon::VERSION is available?

no, looks like is not available

irb(main):001:0> Excon
=> Excon
irb(main):002:0> Excon::VERSION
NameError: uninitialized constant Excon::VERSION
    from (irb):2

Can you investigate this Excon class and ensure it's the one from Excon 0.14.3 gem? Maybe there is some other code defining it?

I ran into the same problem and found out that some gems define a top-level VERSION constant. In my case it was 'its-it', by including their main module into the top-level object.

If excon is loaded after that, the check at https://github.com/geemus/excon/blob/v0.14.3/lib/excon/constants.rb#L2 returns true and prevents Excon::VERSION to be defined correctly.

A workaround is to load excon as soon as possible.

@bauersman are you sure that's the case? Can you please show a code snippet to reproduce that?

https://github.com/geemus/excon/blob/v0.14.3/lib/excon/constants.rb#L2 only checks if VERSION constant
is defined inside Excon module.

In Ruby you always have top level VERSION constant which represents Ruby version.

Sure, minimal test case here: https://github.com/bauersman/ruby-global-constant-inheritance

Edit: the global constant representing the ruby version is RUBY_VERSION, not VERSION

It's a change in behaviour between ruby 1.8 and ruby 1.9. looks like this behaviour only appears in 1.9
