Rails - Apr 2005 - ActiveRecord Enhancement: Help me to package it...please!

I''m working on an enhancement to ActiveRecord.  The the code is
finished and the tests all pass.  I''m a short distance away from
submitting the patch but I''m running into some serious problems
running rake on Windows.

Attempt #1:

In a plain old Windows command shell I run "rake package".  A bunch of
non-Windows commands like "ln" and "rm" scroll by.  The rake
task
fails with:
...
ln examples/shared_setup.rb pkg/activerecord-1.9.1/examples/shared_setup.rb
rm -f pkg/activerecord-1.9.1/examples/validation.rb
ln examples/validation.rb pkg/activerecord-1.9.1/examples/validation.rb
cd pkg
tar zcvf activerecord-1.9.1.tgz activerecord-1.9.1
rake aborted!
undefined method `exitstatus'' for nil:NilClass


Attempt #2:

Ok, since there are a bunch of unix commands up there in #1 I decide
to install cygwin.  I run "rake package" under a cygwin bash shell. 
Rake dies immediately this time:

$ rake package
c:\ruby\bin\ruby.exe: No such file or directory --
/cygdrive/c/ruby/bin/rake (LoadError)

But I check and rake is there!

$ ls -l /cygdrive/c/ruby/bin/rake
-rwxrwxrwx  1 Administrators None 419 Mar 28 18:26 /cygdrive/c/ruby/bin/rake


What is the proper way to set up ruby, rake, and my rails development
tree on Windows so that rake and the rails packaging tasks work?

The sooner I get rake and the rails packaging stuff working the sooner
I can submit my ActiveRecord patch.  I''d really like to get it into
1.0...

thanks for reading,

Kristof

This looks to me like it''s not able to find
"C:\ruby\bin\ruby.exe".
The file /cygdrive/c/ruby/bin/rake probably has as its interpreter
(the shebang line, #!) the hardcoded "C:\......".  Cygwin
isn''t able
to find c:\ruby\bin\ruby.exe because it needs to be referred to under
/cygdrive/c

Yep, rake did had a hardcoded "#! c:\ruby\bin\ruby.exe" at the top.  I
changed it to the right thing for cygwin "#!
/cygdrive/c/ruby/bin/rake" and now it just hangs with no output:

$ rake --verbose

I have to ctrl-c it. "rake --help" also hangs.

Should I give up on Windows for Rails development?  Are any of the
Rails contributers working in a Windows environment?


Kristof

I for one think it''s important to get reasonably good compatibility
with Windows.  It would be nice to write some .bat files to replaces
those shell scripts, but I don''t think Windows can create soft links. 
I know it can create hard links for POSIX compatibility, this is just
a hidden feature from Windows Explorer.  There are ways around that
(http://www.microsoft.com/resources/documentation/Windows/XP/all/reskit/en-us/Default.asp?url=/resources/documentation/Windows/XP/all/reskit/en-us/prkc_fil_baey.asp).
 I''m sure David would welcome a small patch for windows compatibility
provided it doesn''t break the other environments.

I haven''t run into this issue personally, but I''ll check it
out.  I
tried loading the AR unit tests, but it looked like some of the
fixtures or schema scripts were missing.  I was running off a beta
version of rails, so I''ll check that out too.

I''ve always used the tools at http://unxutils.sourceforge.net/ for this
kind of thing. I put them all in a folder and make sure that folder is 
in the path.

Cygwin handles everything differently. The Ruby tools (like Rake) will 
all have C:\-based paths, so you''ll have to change them. I suggest
don''t
mix Cygwin and native Windows. Either do it all in Cygwin or all in Windows.
