AutoSpec exits after executing

Ruby IronRuby

Hello,

I’ve been trying to get AutoSpec to work again.

I execute it using the following command:
pretty:Kona Ben$ ir autospec

However, it just exits.

Any ideas why?

Thanks

So after doing this:

igem install ZenTest
cd C:\ironruby\lib\ironruby\gems\1.8\gems\ZenTest-4.1.4
ir -Ilib bin\autospec

Autospec tries to execute this command:

C:\ironruby\bin\ir.exe -I.;lib;test:…/…/minitest/dev/lib -rubygems -e
“%w[minitest/autorun test/test_focus.rb test/test_autotest.rb
test/test_zentest_mapping.rb test/test_unit_diff.rb
test/test_zentest.rb].each { |f| require f }” | unit_diff -u

The problem is unit_diff will fail to load, since there is no
unit_diff.bat or something like that on the path. To get past that I
just commented out the unit_diff part of lib/autospec.rb#422. However,
it still quits, though the command that is generated does run on its
own.

It quits because IronRuby doesn’t support the call to open it is using
(open with a “|”), and they are swallowing the error msg. Here’s a
smaller repro:

open("| ir.exe -e “puts ‘hi’”", ‘r’)
:0:in open': Exception of type 'IronRuby.Builtins.NotImplementedError' was thrown. (NotImplementedError) from :0:inopen’
from (ir):1

Tomas, is there any work-around to this? … reading a process like a
file, character by character?

To get autotest working right now, you can replace the entire open(){}
call in lib/autotest.rb#243 with simply this:

  puts `#{cmd}`

It won’t print out the test results as they happen, but it’ll at least
show the results when done, and rerun the tests when you change
something.

open with a “|” seems to be the same as popen/popen3. We support both of
those, so it should not be too hard to support open with a “|”. Could
even be written in Ruby code building on top of popen/popen3 (if you
want a workaround right away).
