Bug 496480

Tested this on an x86 and x86_64 installation.  Both machines show the same behaviour.

BTW.

./scripts/generate   

is sufficient to show the bug (normally now a help message should come up).

rails is broken and nobody is interested?

I am interested, I simply haven't had time to look into it. Any suggestions for a fix ?

Nope, i am quite new to rail and tried some research on the internet.
There are various bug reports on such an issue on other versions, but they all fail to provide any solution.

debug output - there at least seems something missing?

at least one error i could remove 
by installing 
yum install rubygem-gem_plugin
yum install rubygem-builder

( i originally did an install by yum install rubygem-rails and installed a all suggested packages by yum).

This what is installed now, but still it doesn't work.

Well in my desperate answer i tried the following... 


# gem install rails                                    
WARNING:  Installing to ~/.gem since /usr/lib/ruby/gems/1.8 and
          /usr/bin aren't both writable.

WORKS!


However i believe this not the way it should be :-)

rubygem-rails-2.3.2-2.fc11 has been submitted as an update for Fedora 11.
http://admin.fedoraproject.org/updates/rubygem-rails-2.3.2-2.fc11

I found the issue - the spec file inadvertantly broke scripts/generate by
patching the line 'require "#{RAILS_ROOT}/config/environment"' in
lib/commands/generate.rb

Built rubygem-rails-2.3.2-2 to address the issue

I find that rubygem-rails-2.3.2-2 is still broken; running 'rails foo' to generate a new rails project shows that a few files are missing:

create  public/favicon.ico
No such file or directory - /usr/lib/ruby/gems/1.8/gems/rails-2.3.2/bin/../lib/rails_generator/generators/applications/app/../../../../../html/favicon.ico

...

create  log/server.log
No such file or directory - /usr/lib/ruby/gems/1.8/gems/rails-2.3.2/bin/../lib/rails_generator/generators/applications/app/../../../../../configs/empty.log

(This list is not necessarily complete.)

I have installed the version from 'gem install rails' for now; obviously this is not how-it-should-be.

This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle.
Changing version to '11'.

More information and reason for this action is here:
http://fedoraproject.org/wiki/BugZappers/HouseKeeping

Two files are missing from Fedora 11 rubygem-rails-2.3.2-2.fc11 rpm package.
So when doing a "rails <application>" it would break right after:

rails myapp
.../...
create  public/favicon.ico
No such file or directory - /usr/lib/ruby/gems/1.8/gems/rails-2.3.2/bin/../lib/rails_generator/generators/applications/app/../../../../../html/favicon.ico

It breaks the first time because gems/rails-2.3.2/Rakefile is looking for favicon.ico and later the empty.log is required by gems/rails-2.3.2/rails_generator/generators/applications/app/app_generator.rb

The two missing files that are missing are:
/usr/lib/ruby/gems/1.8/gems/rails-2.3.2/html/favicon.ico
/usr/lib/ruby/gems/1.8/gems/rails-2.3.2/configs/empty.log

Therefore the following files are not installed in the application tree:
      create  public/robots.txt
      create  public/images/rails.png
      create  public/javascripts/prototype.js
      create  public/javascripts/effects.js
      create  public/javascripts/dragdrop.js
      create  public/javascripts/controls.js
      create  public/javascripts/application.js
      create  doc/README_FOR_APP
      create  log/server.log
      create  log/production.log
      create  log/development.log
      create  log/test.log

I guess those two files where ignored from the rpm spec files because there are empty. There are obviously needed - see Rakefile and CHANGELOG in gems/rails-2.3.2.

BTW, that also breaks rails ajax/javascripts features as the public/javascripts/file are not copied during application structure generation.

Temporary workarounds:

1 - Using gem package instead of standard rpm:
# yum uninstall rubygem-rails
# gem install rails

2 - Adding the two missing empty files (adapt your path /usr/lib/ruby/gems/1.8/gems accordingly)
touch /usr/lib/ruby/gems/1.8/gems/rails-2.3.2/html/favicon.ico
touch /usr/lib/ruby/gems/1.8/gems/rails-2.3.2/configs/empty.log
 
rubygem-rails specs file to add those two files.

I hope it helps

Created attachment 354243 [details]
Patch to spec file to avoid removing required zero-length files

Sometime between the version of this package appearing in Fedora 9
and the current version, the spec file gained a stanza that removes
all zero-length files from the destination tree.  This is an error,
and causes it to remove the following four required empty files from
the package (and nothing else):

./configs/empty.log
./html/favicon.ico
./lib/rails_generator/generators/components/mailer/templates/fixture.rhtml
./lib/rails_generator/generators/components/mailer/templates/view.rhtml

Without the first two files above, you cannot even run 'rails' to
create a new application.  This patch corrects the spec file to no
longer delete these required files.

Verified touching these 4 files and regenerating my rails app works for me. We'll make sure to apply the patch above for f11 and f12. Sorry about that.
