Alexander Færøy= The Trac Configuration File
Trac is configured through the trac.ini file, located in the <projectenv>/conf directory. The trac.ini configuration file and its parent directory should be writable by the web server.
Trac monitors the timestamp of the file to trigger a complete environment reload and flush its caches when the timestamp changes. Most changes to the configuration will be reflected immediately, though changes to the [components] or [logging] sections will require restarting the web server. You may also need to restart the web server after creating a [#GlobalConfiguration global configuration] file when none was previously present.
== Global Configuration
Configuration can be shared among environments using one or more global configuration files. Options in the global configuration will be merged with the environment-specific options, with local options overriding global options. The global configuration file is specified as follows:
[inherit]
file = /path/to/global/trac.iniMultiple files can be specified using a comma-separated list.
Note that you can also specify a global option file when creating a new project, by adding the option --inherit=/path/to/global/trac.ini to [TracAdmin#initenv trac-admin]'s initenv command. If you do not do this but nevertheless intend to use a global option file with your new environment, you will have to go through the newly generated conf/trac.ini file and delete the entries that will otherwise override those set in the global file.
#inherit-sectiontemplates_dir for sharing global templates and plugins_dir, for sharing plugins. Those entries can themselves be specified in the shared configuration file, and in fact, configuration files can even be chained if you specify another [inherit] file there.
Note that the templates found in the templates/ directory of the TracEnvironment have precedence over those found in [inherit] templates_dir. In turn, the latter have precedence over the installed templates, so be careful about what you put there. Notably, if you override a default template, refresh your modifications when you upgrade to a new version of Trac. The preferred way to perform TracInterfaceCustomization is still to write a custom plugin doing an appropriate ITemplateStreamFilter transformation.
