I have just upgraded to Ruby 1.8.7 and Rails 2.2.2. My previous project
was at Ruby 1.8.6 and Rails 2.0.2. My platform is Windows and Webrick
for development.
When I run Webrick, the server starts without error, the application
runs, database connections work and I can click through the pages and
display data. But it does not serve any stylesheets or javascript
files. What's interesting is that images are displayed. In the log
file, I get a 500 error after it attempts to retrieve a stylesheet or
javascript. This occurs everytime.
Example of attempt to retrieve prototype.js (a 500 error):

You can tell whether it changed anything by checking your current
version against the version in your version control repository. If
you are not using one (git for example) start by setting one up. When
messing about upgrading rails and so on you need to be able to track
what you have done, revert experimental changes, and so on. A day or
two spent learning git will be recovered very quickly.
As much of the trace as I can get from my Windows command prompt. It
doesn't log this to log/development.log. You'll see GET calls and then
the 500 error followed by the "private method `gsub!'" error message
repeatedly. Seems to affect all of the static files---stylesheets,
javascripts, images. Sometimes it pulls images from my cache and if I
refresh the page the image is missing again...

I use subversion. Not much changed after executing "rake rails:update"
on my current project. I think it mainly changed the boot.rb file.
What is odd is that I even created a new rails app from scratch and it
is also having the same problem serving up anything from the public
folder---stylesheets, javascripts, images, etc... If I start webrick on
this new app, it appears that the "new rails app" page loads with the
images, but if I refresh, it immediately gives me the 500 errors on the
static content.
I think I've worked through most of the other problems related to all
the various plugins I'm using, but this issue still is puzzling why even
a new rails app has the same problem.
Out of interest have you tried mongrel?
script/server mongrel
Otherwise I am out of my depth I am afraid.
Colin
Well, I executed "gem install mongrel", then "ruby script/server
webrick" and everything is loading!! What a bad problem with webrick.
My staging server is mongrel, but my production is phusion passenger
(which is a breeze to setup). I hope Passenger will be kind when I make
the next release to production!
I think it even cleared up an annoying "stack level too deep" error I
was getting with webrick and not caching classes in development.
Mongrel isn't complaining.
Well, I executed "gem install mongrel", then "ruby script/server
webrick" and everything is loading!!
I presume you mean "ruby script/server mongrel"
Colin
Yes... Sorry. Webrick still on the mind.
ruby script/server mongrel
Works!
To continue using Webrick, instead of switching to Mongrel, you can also
just edit line 15 of lib/ruby/1.8/webrick/htmlutils.rb to read
str = string ? string.to_s.dup : ""
The problem is that NotModified exception is getting passed to
HTMLUtils::escape as a class, rather than a string (originally raised in
HTTPServlet::DefaultFileHandler). Since the only things that can really
be HTML escaped are strings, it should be safe to always convert the
input to string.
I suspect that the potential performance penalty may prevent a solution
like that from making it to the standard ruby library, but it's a simple
workaround.
Alternatively, in the handle_file method of webrick's DispatchServlet
(lib/webrick_server.rb in the rails gem), before it calls res.set_error
with the exception, you could force the err.message to be a string, or
even clear the message, since I think it's discarded anyway for
NotModified.
Thank you very much! How very obvious to change that line. A pitty I
haven't tried to change it that way.
But now everything works just fine. I had the nearly same problem with
the same versions of Ruby and Rails but on Ubuntu. In my case
stylesheets etc. were loaded after some reloading of the page.
