Using this method may lead to Trac delivering the content of another Trac environment, as the variable may be filled with the path of a previously viewed Trac environment. 51 If you are using multiple `.wsgi` files (for example one per Trac environment) you must ''not'' use `os.environ['TRAC_ENV']` to set the path to the Trac environment. Using this method may lead to Trac delivering the content of another Trac environment, as the variable may be filled with the path of a previously viewed Trac environment. 52 52 53 53 To solve this problem, use the following `.wsgi` file instead: … … 59 59 import trac.web.main 60 60 def application(environ, start_response): 61 environ['trac.env_path'] = '/usr/local/trac/mysite' 61 environ['trac.env_path'] = '/usr/local/trac/mysite' 62 62 return trac.web.main.dispatch_request(environ, start_response) 63 63 }}} 64 64 65 For clarity, you should give this file a `.wsgi` extension.

Versions prior to 2.4 in the 2.X branch have problems with some Apache configurations that use WSGI file wrapper extension. This extension is used in Trac to serve up attachments and static media files such as style sheets. If you are affected by this problem, attachments will appear to be empty and formatting of HTML pages will appear not to work due to style sheet files not loading properly. Another frequent symptom is that binary attachment downloads are truncated.
