[drchiu]

Getting this error: NoMethodError (private method `getc' called for
#<PhusionPassenger::Utils::RewindableInput:0x104131988>):

Scenario:
- Setting up two rails application on two separate VirtualHost domain
(eg. app1.local, app2.local)
- Making an ActiveResource call from one app to the second app

Error Trace:

-- Begin --
Started POST "/stores.xml" for 127.0.0.1 at 2010-04-17 23:18:39
Error occurred while parsing request parameters.
Contents:

</store>

NoMethodError (private method `getc' called for

Any ideas?

This is a bug in either your application or in ActiveResource.
According to the Rack specification, rack.input does not have to
respond to #getc: http://rack.rubyforge.org/doc/SPEC.html

You're right. I'm inclined to think this is a bug in Rails 3 beta 3
ActionController.

Calling from Rails 2.3.5 ActiveResource => Rails 3.0.0 beta 3
ActionController will cause this error, but in reverse with a Rails 3
ActiveResource => Rails 2.3.5 ActionController seems okay.

This error seems to be caused whenever XML is being sent. Will try and
track this down. Darn trace and log doesn't tell me much.

Thanks anyway Hongli.

I'm getting the same error. However, I do not see this error using
webrick, and in testing using rack. I only have this issue with
passenger which lead me to believe it is a passenger issue.
However, as the ticket has been resolved maybe not. Just thought I'd
point this out for others.

That is because Webrick exposes a StringIO as the rack.input, and
StringIO responds to #getc. But according to the Rack spec rack.input
doesn't not *have* to respond to #getc. Rails is violating the Rack
spec by assuming that #getc is available everywhere.
