Attachment_Fu and Premature end of script

[raygao]

Hi,

I am trying to write an application for my church. I have an option
for uploading images to a controller. It is using attachment_fu. It
works fine without any problem in Mongrel_rails.

But, when I tried to deploy it to Phusion Passenger, I consistently
gets "Premature end of script headers". And, I even set the httpd.conf
to debug. I still don't see any outputs from where ti is causing it.
It is pretty clear this problem only shows up in Phusion Passenger.
And, the problem is aways with uploading the file and Attachment_fu.

Is there a solution for this problem?

Many thanks,

-Ray

This is very strange. When I set the environment to 'development', everything works fine. But, when I set it to 'test' or 'production', I get 'Premature end of script headers' error.

Very strange.

Is it true, that you must get a license to run the Phusion Passenger in 'production' or 'test' mode?

No, Phusion Passenger is open source.

Which Rails version are you using? And have you tried looking in the
web server error log?

Hi Hong,

I am using Rails 2.3.5 on Ruby 1.8.7 on Mac Snow Leopard (10.6)

When I change the RailsEnv => development. It works well. But, when I set it to 'test' or 'production', I get the following error.

This is apparent with Attachment_fu. The problem is due to file upload.

My setting is as follows:

<VirtualHost postcard.localhost.com:3000>

    RailsEnv test    #works when it is development, not test or production

    RailsDefaultUser testuser

    ServerName postcard.localhost.com

    DocumentRoot /Users/testuser/NetBeansProjects/postcard/public

    ErrorLog /Users/testuser/NetBeansProjects/postcard/log/apache_fusion_error.log

    LogLevel debug

    PassengerLogLevel 3

    PassengerTempDir /Users/testuser/NetBeansProjects/postcard/log/temp

    CustomLog /Users/testuser/NetBeansProjects/postcard/log/apache_fusion_custom.log common

      <Directory /Users/testuser/NetBeansProjects/postcard/public>

         AllowOverride all              

         Options -MultiViews       

      </Directory>

</VirtualHost>

Log from the custom error file:

I am also attaching the log file here as well.

There's a bug in Rails 2.3.5 which causes some error messages not to
be displayed. Try applying the patch here:
https://rails.lighthouseapp.com/projects/8994/tickets/3577-failsafe-middleware-should-flush-the-logger
With this you might see a proper error message in the logs.

Hi,

Here is the mini app that I wrote to test this problem with Attachment_fu. I have spent quite bit of time. It is still acting erratically. Can someone please help me and look at the problem?

Thanks,
