= The Trac Configuration File = ''[Note To Editors] Please discuss documentation changes in the [#Discussion] section. Even better, send us [TracDev/SubmittingPatches documentation patches] against the ''code'' (i.e. where the configuration entries are documented), either on Trac-dev or on new tickets. '' [[TracGuideToc]] [[PageOutline]] Trac configuration is done by editing the '''`trac.ini`''' config file, located in `<projectenv>/conf/trac.ini`. Changes to the configuration are usually 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 global configuration file when none was previously present. The `trac.ini` configuration file and its parent directory should be writable by the web server, as Trac currently relies on the possibility to trigger a complete environment reload to flush its caches. == Global Configuration == In versions prior to 0.11, the global configuration was by default located in `$prefix/share/trac/conf/trac.ini` or `/etc/trac/trac.ini`, depending on the distribution. If you're upgrading, you may want to specify that file to inherit from. Literally, when you're upgrading to 0.11, you have to add an `[inherit]` section to your project's `trac.ini` file. Additionally, you have to move your customized templates and common images from `$prefix/share/trac/...` to the new location. Global options will be merged with the environment-specific options, where local options override global options. The options file is specified as follows: {{{ [inherit] file = /path/to/global/trac.ini }}} Multiple 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. There are two more entries in the [[#inherit-section| [inherit] ]] section, `templates_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 be sure to refresh your modifications when you upgrade to a new version of Trac (the preferred way to perform TracInterfaceCustomization being still to write a custom plugin doing an appropriate `ITemplateStreamFilter` transformation). == Reference for settings This is a brief reference of available configuration options, and their default settings. ''Note that the [hg], [spam-filter], [translatedpages], [vote], [wikiextras] and [wikiextras-symbols] sections below are added by plugins enabled on this Trac, and therefore won't be part of a default installation.'' {{{ #!comment Suggest your documentation fixes in the Discussion section at the bottom of the page, or better send us patches against the corresponding docstrings you'll find in the code! Please don't waste your time by editing the HTML code below, changes won't be picked up. }}} [[TracIni]] == Discussion == ''Please discuss documentation changes here. Even better, send us documentation patches against the code, either on Trac-dev or on new tickets.'' ---- See also: TracGuide, TracAdmin, TracEnvironment
