Broken JRuby support

[mrbrdo]

At some point in time you broke JRuby support by using fork (unsupported) in https://github.com/nadarei/mina/blob/master/lib/mina/exec_helpers.rb

You could perhaps use threads for this purpose and rescue Interrupt instead of trap('INT').

PS: I've monkey-patched to use threads and seems to work fine

Here comes the PR.

Could you share the code, please?

It would be great if the Mina site showed that it was incompatible with Jruby. Wasted hours.

[mrbrdo]

Show code? Don't you see the pull request?

[mrbrdo]

@rstacruz could you consider merging my PR? We JRuby users would really appreciate it.

[mrbrdo]

@designium if you need it now, add 'mina-extras' to your Gemfile and in your deploy.rb require 'mina-extras/jruby-patch'

[mrbrdo]

@rstacruz any response would be nice.

I really do not know if this is fixed. If someone tried using newer mina version with JRuby and doesnt work please repoen the task

Hi @mrbrdo
So did this finally got solved and properly patched for the following versions?
The status looks uncertain.
Thanks!

[mrbrdo]

Yes since the patch is merged I think it should work now.

Sorry to raise the old issue, but this seems to be broken again as of 1.0.6. Trying to run it under jruby 9, I get the following error:

> $ mina deploy
mina aborted!
NotImplementedError: fork is not available on this platform

[zhum]

The same problem! Please, fix for jruby...

[vicvans20]

Same problem with jruby 9.1.7.0

[prasadsurase]

Same problem with jruby 9.1.15.0

[zhum]

Please, accept my patch... #581
I use it in production, my patched mina works fine with jruby.
