Rails - Sep 2005 - (newbie) rails app not working after subversion integration?

hello,

if anybody could  please help, I''m very late with this project and  
have been wasting a lot of time (days and days) getting past the  
learning curve to get the infrastructure up (fcgi, rmagick... and now  
svn integration). i come from dirty-php-scripting and am a newbie at  
all of this :P

I have a rails app that I''ve been developing locally on os x.  
originally I was uploading the app directly to my textdrive account  
when updating, and then restarting apache. this was working fine, I  
could see the site running on textdrive each time, all funcionality  
was there, production.log was being written to.

I''ve seen strong recommendations from the rails list and textdrive  
forum to use subversion, and I decided to make the move to work with  
it. after a bit of a learning curve, I finally created a svn repo on  
textdrive, imported the app into it, and have been checking it out to  
my local machine, commiting back, and then checking out the current  
copy to my /web directory on textdrive. I followed this howto http:// 
wiki.rubyonrails.com/rails/show/HowtoUseRailsWithSubversion on the  
rails wiki.

BUT, now I''m getting an application error (both locally and on txd),  
and the logs aren''t being written to. (the howto involves making svn  
ignore the log files by deleting them, committing the working copy,  
then setting propset to ignore, updating, then commiting again.). so  
I checked the apache logs on my txt acct, and nothing useful  
appeared, just simple requests and browser info. on my local apache  
logs, I get the following:

     /usr/lib/ruby/site_ruby/1.8/rubygems/source_index.rb:3:in  
`require'': No such file to load -- forwardable (LoadError)
     from /usr/lib/ruby/site_ruby/1.8/rubygems/source_index.rb:3
     from /usr/lib/ruby/site_ruby/1.8/rubygems.rb:381:in `require''
     from /usr/lib/ruby/site_ruby/1.8/rubygems.rb:381
     from /Users/souza/Sites/star/public/../config/environment.rb: 
48:in `require''
     from /Users/souza/Sites/star/public/../config/environment.rb:48
     from /Users/souza/Sites/star/public/dispatch.fcgi:21:in `require''
     from /Users/souza/Sites/star/public/dispatch.fcgi:21

I''m lost as to what''s going on... I''m assuming
something changed when
I started using svn, but don''t know what. I changed permissions on  
the log to 755 and even 777 to try seeing the logs... also did that  
for public/... what''s going on?

thanks
oliver

Hi Oliver,

I can''t give you a quick answer on this one but here''s how
I''d approach
the situation:

First of all, I''d make sure the contents of my ./script/* directory was
the same as in svn railties/bin.

If that wasn''t the issue then I''d take a closer look at the
stacktrace
in the apache log:

When you see ''require'': no such file to load
''blah'' that (AFAIK) means
there is a "require" command on a line somewhere that refers to a file
that ruby can''t locate.

Step down the stacktrace lines (you''re "walking up the call
stack") and
look for the first file you can see that is one of yours.  In this case 
it appears to be environment.rb, line 48.  I consider that one of 
"yours" because its the first one you''re likely to have
edited.

This should be your starting point because for now, you have to assume 
that this is *your* fault so you start there.

What''s at that line?

As for other clues about what might be happening (bearing in mind that 
I too am a bit new to this) ''forwardable'' rings a bell because
it''s a
module in the standard ruby library.  See 
http://www.ruby-doc.org/stdlib/libdoc/forwardable/rdoc/

Sorry I can''t say "twiddle the widget and you''ll be
fine" - but this
should give you something to start on.

Regards,
Trevor

Well, /usr/lib/ruby/site_ruby/1.8/rubygems/source_index.rb, on line 3,
is not able to load forwardable.rb.  Do you have that file installed?

been looking for it but haven''t found it yet. where should it be?  
from searching the web it seems like it''s part of ruby?

during installation of rmagick and imagemagick, I ended up  
reinstalling ruby...

and I got this error a couple of times, but after finishing  
installing everything else (readline, gems, rails, rmagick), it went  
away and the app was running ok.

so would this be a problem that would keep rails from even loading,  
and so not write to the logs?

Hi Trevor,
thanks, what you said about the stack trace made sense and i''m  
checking environment.rb... line 48 requires ruby gems:

     require ''rubygems'' unless
File.directory?("#{RAILS_ROOT}/vendor/
rails")

I don''t have a /vendor/rails directory, and the only thing I changed  
in environment.rb was this line:

     RAILS_ENV  = ENV[''RAILS_ENV''] ||
''development''

changed it ''development'' to ''production'' (so
that I could commit the
app set to production mode) and then back again to
''development''. I
then tried to make svn ignore this file so that on future commits I  
didn''t change the app online to development mode again. could this be  
affecting the way rubygems loads ''forwardable''? am I just
getting
this wrong about making svn ignore environment.rb?

like I said to Joe, I had a similar problem appear when installing  
Rmagick (forwardable.rb not loading), but then it went away by  
itself, not sure how exactly.

as for the contents of ./script/, you lost me here... svn railties/bin?

ok, I''ve found it:

/usr/local/lib/ruby/1.8/forwardable.rb

does this mean rubygems isn''t working right? I''m guessing
rubygems
itself isn''t being loaded correctly by rails, and so this is  
happening... is this assumption correct? what could be causing this?

What it likely means is that you don''t have read permission on that
file.

What do you get from:
ls -l /usr/local/lib/ruby/1.8/forwardable.rb

Ray

ok, I set its permissions to 755, but I''m still getting the error :P

ok, finally resolved it... I put in a fresh environment.rb in, fresh  
logs and a fresh dispatch.fgi and it works now. not sure why, but...

newbie pains, newbie pains

thanks guys

I had issues with apache, subversion, and static fcgi servers bogging
down after an update.  I switched to a dynamic fcgi setup, and things
have been better since.
