Redmine

Can you attach your Redmine log because I'm not able to reproduce with current trunk.

Nothing to attach. There are no entries created in the production log when this error happens.

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, root@localhost and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log.
Apache/2.2.3 (CentOS) Server at pas.harte-lyne.ca Port 443

I discover that the same problem occurs when attempting to upload a file to a wiki page or on the files page.

Please try to reproduce with webrick:

ruby script/server -e production -p <port>

But I see this. I have not changed permissions or ownership on any directories. Would updating from svn do so?

Redmine 0.8.0.devel.2658 (PostgreSQL)
Default administrator account changed True
Attachments directory writable (/var/data/pas-redmine/files) False
Plugin assets directory writable (/var/data/pas-redmine/public/plugin_assets) False
RMagick available (optional)

Webrick works fine. But I use https protocol with Apache. I see this in the ssl.error.log when trying to delete an attachment.

[Tue May 12 17:02:47 2009] [error] [client 216.185.71.24] Premature end of script headers: attachments, referer: https://pas.harte-lyne.ca/projects/hll-administration/files

I probably should mention that I use mod_rails (Phusion Passenger) as well.

I can't do anything without the application stack trace.

There is no stack trace. The application does not blow up. It simply renders the error and permits one to continue. I believe that the error message is related to this:

http://httpd.apache.org/docs/1.3/misc/FAQ-F.html#premature-script-headers

I think that the issue is either the permissions or the ownership of the directory and files. In my installation the apache user belongs to the pas group and the pas user and group own all of the redmine directory tree. This configuration worked up until the last update. I do not know what changed but I suspect this is where the problem is.

How does redmine determine these values or where are they set?

I looked into the admin controller to discover how this is done and this is what I found:

#

So, why am I getting un-writable results when accessing the application through apache?

# User/Group: The name (or #number) of the user/group to run httpd as.
#  . On SCO (ODT 3) use "User nouser" and "Group nogroup".
#  . On HPUX you may not be able to use shared memory as nobody, and the
#    suggested workaround is to create a user www and use that user.
#  NOTE that some kernels refuse to setgid(Group) or semctl(IPC_SET)
#  when the value of (unsigned)Group is above 60000; 
#  don't use Group #-1 on these systems!

User apache
Group apache

Even this works:

# ll -d files
drwxrwxr-x 3 pas pas 20480 May 12 16:59 files
# su apache
sh-3.2$ script/console

This was an issue with Passenger. Due to some local changes to environment.rb the ownership of that file was inadvertently changed during the Redmine upgrade process and this was not noticed. The owner of the environment.rb file is the user id that passenger uses for that application. Resetting the ownership and restarting the service correctly resolved the issue.
