    to use mod python for all locations different from root while having the possibility of placing a custom home page for root in your DocumentRoot folder You can also use the same authentication realm for all of the projects using a LocationMatch directive LocationMatch projects login AuthType Basic AuthName Trac AuthUserFile var trac htpasswd Require valid user LocationMatch Virtual Host Configuration Below is the sample configuration required to set up your trac as a virtual server i e when you access it at the URLs like http trac mycompany com VirtualHost DocumentRoot var www myproject ServerName trac mycompany com Location SetHandler mod python PythonInterpreter main interpreter PythonHandler trac web modpython frontend PythonOption TracEnv var trac myproject PythonOption TracUriRoot Location Location login AuthType Basic AuthName MyCompany Trac Server AuthUserFile var trac myproject htpasswd Require valid user Location VirtualHost This does not seem to work in all cases What you can do if it does not Try using LocationMatch instead of Location Location may in your server setup refer to the complete host instead of simple the root of the server This means that everything including the login directory referenced below will be sent to python and authentication does not work i e you get the infamous Authentication information missing error If this applies to you try using a sub directory for trac instead of the root i e web and web login instead of and login For a virtual host that supports multiple projects replace TracEnv var trac myproject with TracEnvParentDir var trac Note DocumentRoot should not point to your Trac project env As Asmodai wrote on trac suppose there s a webserver bug that allows disclosure of DocumentRoot they could then leech the entire Trac environment Troubleshooting In general if you get server error pages you can either check the Apache error log or enable the PythonDebug option Location projects myproject PythonDebug on Location For multiple projects try restarting the server as well Expat related segmentation faults This problem will most certainly hit you on Unix when using Python 2 4 In Python 2 4 some version of Expat an XML parser library written in C is used and if Apache is using another version this results in segmentation faults As Trac 0 11 is using Genshi which will indirectly use Expat that problem can now hit you even if everything was working fine before with Trac 0 10 See Graham Dumpleton s detailed explanation and workarounds for the issue Form submission problems If you re experiencing problems submitting some of the forms in Trac a common problem is that you get redirected to the start page after submission check whether your DocumentRoot contains a folder or file with the same path that you mapped the mod python handler to For some reason mod python gets confused when it is mapped to a location that also matches a static resource Problem with virtual host configuration If the Location directive is used setting the DocumentRoot may result in a 403 Forbidden

  • TracBrowser – Opus Project
    will show the contents of the file Clicking on the revision number of a file or directory will take you to the TracRevisionLog for that file Note that there s also a Revision Log navigation link that will do the same for the path currently being examined It s also possible to browse directories or files as they were in history at any given repository revision The default behavior is to display the latest revision but another revision number can easily be selected using the View revision input field at the top of the page since 0 11 The color bar next to the Age column gives a visual indication of the age of the last change to a file or directory In the default configuration blue is older and red is newer but this can be configured At the top of the browser page there s a drop down menu which you can use to select some interesting places in the repository for example branches or tags This is sometimes referred to as the browser quickjump facility The precise meaning and content of this menu depends on your backend For Subversion this list contains by default a few branches trunk and any sub folder of the latest branches top level folder and a few tags any sub folder of the latest tags top level folder This can be configured for more advanced cases If you re using a Javascript enabled brower you ll be able to expand and collapse folders in place by clicking on the arrow head at the right side of a folder Alternatively the keyboard can also be used for this use j and k to go to the next or previous entry and o or Enter to toggle between expanded and collapsed state of the
