unsupported signal SIGCHLD #34

Closed danil-z closed 12 years ago

danil-z commented 12 years ago

The error I'm seeing is as follows, when I run 'bundle exec guard':

ERROR: Invalid Guardfile, original error is: unsupported signal SIGCHLD

As soon as I take the spork guard out it runs fine again. I am new to ruby/rails but anything you need from me let me know. I am running guard 0.8.2, spork 0.9.0.rc and guard-spork 0.3.0. Also, I am on Window 7 and run rails 3.1 and ruby 1.9.2.

Thanks for putting this in for me!

thibaudgg commented 12 years ago

Ok it should be fixed now, please can you try master branch before I make a release.

gem 'guard-spork', :git => 'git://github.com/guard/guard-spork.git'

Gave it a try just now and I'm getting the following error and it just seems to be sitting at Booting Rails for test environment.

thibaudgg commented 12 years ago

Ok, so it seems that fork isn't supported on Windows either :(. Please can you try with guard-spork version 0.1.0 & 0.1.5 to see if it works.

buethling commented 12 years ago

Version 0.1.0 results:

PS C:\Users\Chris\Documents\Aptana Studio 3 Workspace\StoryMode> bundle exec guard start Guard is now watching at 'C:/Users/Chris/Documents/Aptana Studio 3 Workspace/StoryMode' 'kill' is not recognized as an internal or external command, operable program or batch file. Starting Spork for RSpec The process cannot access the file because it is being used by another process. ERROR: Could not start Spork for RSpec. Make sure you can use it manually first.

Version 0.1.5 results:

Notes:

Looks like 0.1.5 ran fine except it looked like it used spork but may have also started up it's on version of rails test? Thanks for your help on this!

thibaudgg commented 12 years ago

Can you try to add the win32-process gem in your Gemfile (with the master version of guard-spork):

gem 'win32-process', :require => 'win32/process'

It should add fork and kill support to Windows

buethling commented 12 years ago

Looks like fork() is not working in win32-process at least on my machine (Win7). I'm getting this error again:

Starting Spork for RSpec ERROR: Guard::Spork failed to achieve its , exception was: NotImplementedError: fork() function is unimplemented on this machine

thibaudgg commented 12 years ago

Ok, you should open an issue about this onwin32-process gem. I think I cannot do more for this on the guard-spork side, sorry.

buethling commented 12 years ago

Ok, thanks for your help on this, I really appreciate it.

thibaudgg commented 12 years ago

Thanks, you're welcome.

EdJones commented 12 years ago

I submitted one: https://github.com/djberg96/win32-process/issues/5

thibaudgg commented 12 years ago

Great, thanks!

EdJones commented 12 years ago

The win32-process owner answered thusly:

"I don't know what guard-spork is, but Process.fork on Windows was an experimental implementation that I wouldn't use in production. And SIGCHLD is an unsupported signal on Windows anyway afaik. The guard-spork library should either try to use threads on Windows or declare that it isn't supported on Windows."

thibaudgg commented 12 years ago

The need of SIGCHLD has already been removed but the current guard-spork implementation need Process.fork so I don't think Windows support will be possible right now, sorry. :(

buethling commented 12 years ago

That's ok, thanks for your help! It seems like maybe Cygwin is the way to go for RoR developers on Windows.

rakeshyadavitan commented 11 years ago

Thanx!!!!!

guard-spork, version - 0.1.5 is working fine with windows
