Subject: FW: [Rake-devel] the origin of the strange bug on win2k

Hi all,

I've forwarded this from the Rake dev mailing list in the hopes that
someone can help out.  There appears to be a shell problem, and we're
not sure what the proper way is to handle this on Win32.

Any ideas?

Thanks,

Dan

Hello!

By strange bug, I mean:
----8<----
-e:1:in `exit': no implicit conversion from nil to integer (TypeError)
         from -e:1
----8<----
that appeared /while/ unittests of rake were running.

I think it is because comspec (the win2k shell) doesn't substitute
variables the 
same way as unix shell does.

----8<----
C:\usr\ruby\lib\ruby\gems\1.8\gems\rake-0.5.4.1>set RAKE_TEST_RUBY=123

C:\usr\ruby\lib\ruby\gems\1.8\gems\rake-0.5.4.1>echo $RAKE_TEST_RUBY
$RAKE_TEST_RUBY

C:\usr\ruby\lib\ruby\gems\1.8\gems\rake-0.5.4.1>echo %RAKE_TEST_RUBY%
123

C:\usr\ruby\lib\ruby\gems\1.8\gems\rake-0.5.4.1>ruby -e "exit
$RAKE_TEST_RUBY" -e:1:in `exit': no implicit conversion from nil to
integer (TypeError)
         from -e:1

C:\usr\ruby\lib\ruby\gems\1.8\gems\rake-0.5.4.1>ruby -e "puts
%RAKE_TEST_RUBY%" 123
----8<----

Concerning the tests, the problem lies in test/testfileutils.rb at line
99:
----8<----
ruby %{-e "exit $RAKE_TEST_RUBY"} do |ok, status|
  assert(!ok)
  assert_equal 123, status.exitstatus
  block_run = true
end
----8<----

Unfortunatly, replacing $RAKE_TEST_RUBY with %RAKE_TEST_RUBY% doesn't
work. I've 
conducted some tests to see what could work, see the attachment. ... But
I don't 
find any solution yet.
