= Trac on Mandrake Linux =

'''Warning''': Mandrake Linux has been renamed to [http://trac.edgewall.org/wiki/TracOnMandriva Mandriva Linux], which itself has also been discontinued as of 2011.

== Mandrake 10.1 ==

Trac is included in the [http://www.mandrakelinux.com Mandrake Linux] contribs repository, version 0.7.1 for 10.1. The latest version is in Mandrake Linux Cooker. '''Do not''' install binary Cooker packages on any stable distribution as it will break your installation (#279).

Trac should be available through urpmi or rpmdrake, if you have the proper urpmi source in your configuration file. Simply type:

{{{
# urpmi trac
}}}

 * http://www.urpmi.org/
 * http://cvs.mandrakesoft.com/cgi-bin/cvsweb.cgi/contrib-SPECS/trac/

If you want to install Trac on an older release of Mandrake, please be sure to rebuild it (use `rpm --rebuild trac....src.rpm`). 

If the release tag seems weird, please look at this page http://qa.mandrakesoft.com/twiki/bin/view/Main/DistroSpecificReleaseTag

Once Trac is installed, you can use trac-admin to add a repository and use the example config file provided to start using Trac.

=== Possible Problems ===
==== msec 5 Issues ====
If Mandrake is running at msec 5, Trac will raise errors like the one below when you attempt to access it from your browser.

Oops...

Trac detected an internal error:

malformed database schema - unable to open a temporary database file for storing temporary tables

If you reduce msec to 3, Trac will work as it should. The problem is, sqlite cannot create temp files in /tmp at msec 5 because /tmp is set to 1733. I tried to work around this by giving apache rwx privileges on /tmp by using acl like so:

{{{
setfacl -m u:apache:rwx /tmp
}}}

That worked until the next time msec swept through the filesystems and reset the permissions back to what they were defined to be in /usr/share/msec/perm.5 .

That would change the acl mask, which would, once again, result in Trac raising errors like the one above. The solution, as imperfect as it is, is to create a file /etc/security/msec/perm.local into which the following should be entered.

{{{
/tmp/   root.root       1777
}}}

This specifies an exception to the default permissions defined in /usr/share/msec/perm.5, which prevents msec from changing the permissions on /tmp as it periodically sweeps through the filesystem.

== Mandrake 10.2 ==

For Mandrake Linux 10.2, a wizard has been added. Install drakwizard-trac, run drakwizard, and follow the instructions.
