The Trac Configuration File
Table of Contents
Trac configuration is done by editing the trac.ini config file, located in <projectenv>/conf/trac.ini.
Global Configuration
Since version 0.9, Trac can also read the configuration from a global trac.ini file. These global options will then be merged with the environment-specific options, where local options override global options.
The global configuration is by default localted in $prefix/share/trac/conf/trac.ini. It can be moved to a different location (for example, /etc/trac.ini), but that requires changing the file trac/siteconfig.py which gets created when Trac is installed.
Reference
This is a brief reference of available configuration options.
[attachment]
| max_size | Maximum allowed file size (in bytes) for ticket and wiki attachments. |
| render_unsafe_content | Whether attachments should be rendered in the browser, or only made downloadable. Pretty much any file may be interpreted as HTML by the browser, which allows a malicious user to attach a file containing cross-site scripting attacks. For public sites where anonymous users can create attachments it is recommended to leave this option disabled (which is the default). |
[header_logo]
| alt | Alternative text for the header logo. |
| height | Height of the header logo image in pixels. |
| link | URL to link to, from the header logo. |
| src | URL of the image to use as header logo. It can be absolute, server relative or relative. If relative, it is relative to one of the /chrome locations: site/your-logo.png if your-logo.png is located in the htdocs folder within your TracEnvironment; common/your-logo.png if your-logo.png is located in the folder mapped to the htdocs_location URL. Only specifying your-logo.png is equivalent to the latter. |
| width | Width of the header logo image in pixels. |
[inherit]
| plugins_dir | Path to the shared plugins directory. Plugins in that directory are loaded in addition to those in the directory of the environment plugins, with this one taking precedence. (since 0.11) |
| templates_dir | Path to the shared templates directory. Templates in that directory are loaded in addition to those in the environments templates directory, but the latter take precedence. (since 0.11) |
[logging]
| log_file | If log_type is file, this should be a path to the log-file. Relative paths are resolved relative to the log directory of the environment. |
| log_format | Custom logging format. If nothing is set, the following will be used: Trac[$(module)s] $(levelname)s: $(message)s In addition to regular key names supported by the Python logger library (see http://docs.python.org/library/logging.html), one could use: - $(path)s the path for the current environment - $(basename)s the last path component of the current environment - $(project)s the project name Note the usage of $(...)s instead of %(...)s as the latter form would be interpreted by the ConfigParser? itself. Example: ($(thread)d) Trac[$(basename)s:$(module)s] $(levelname)s: $(message)s (since 0.10.5) |
| log_level | Level of verbosity in log. Should be one of (CRITICAL, ERROR, WARN, INFO, DEBUG). |
| log_type | Logging facility to use. Should be one of (none, file, stderr, syslog, winlog). |

| pygments_default_style | The default style to use for Pygments syntax highlighting. |
| pygments_modes | List of additional MIME types known by Pygments. For each, a tuple mimetype:mode:quality has to be specified, where mimetype is the MIME type, mode is the corresponding Pygments mode to be used for the conversion and quality is the quality ratio associated to this conversion.

| restrict_owner | Make the owner field of tickets use a drop-down menu. Be sure to understand the performance implications before activating this option. See Assign-to as Drop-Down List.

| auto_reload | Automatically reload template files after modification. |
| backup_dir | Database backup location |

| htdocs_location | Base URL for serving the core static resources below /chrome/common/. It can be left empty, and Trac will simply serve those resources itself. Advanced users can use this together with trac-admin ... deploy <deploydir> to allow serving the static resources for Trac directly from the web server. Note however that this only applies to the <deploydir>/htdocs/common directory, the other deployed resources (i.e. those from plugins) will not be made available this way and additional rewrite rules will be needed in the web server. |
| mainnav | Order of the items to display in the mainnav navigation bar, listed by IDs. See also TracNavigation?. |
| metanav | Order of the items to display in the metanav navigation bar, listed by IDs. See also TracNavigation?. |

| timeout | Timeout value for database connection, in seconds. Use '0' to specify no timeout. (Since 0.11) |
| use_base_url_for_redirect | Optionally use [trac] base_url for redirects. In some configurations, usually involving running Trac behind a HTTP proxy, Trac can't automatically reconstruct the URL that is used to access it. You may need to use this option to force Trac to use the base_url setting also for redirects. This introduces the obvious limitation that this environment will only be usable when accessible from that URL, as redirects are frequently used. (since 0.10.5) |
[wiki]
| ignore_missing_pages | Enable/disable highlighting CamelCase links to missing pages (since 0.9). |
| max_size | Maximum allowed wiki page size in bytes. (since 0.11.2) |
| render_unsafe_content | Enable/disable the use of unsafe HTML tags such as <script> or <embed> with the HTML WikiProcessor (since 0.10.4). For public sites where anonymous users can edit the wiki it is recommended to leave this option disabled (which is the default). |

| split_page_names | Enable/disable splitting the WikiPageNames with space characters (since 0.10). |
[components]
(since 0.9)
This section is used to enable or disable components provided by plugins, as well as by Trac itself. The component to enable/disable is specified via the name of the option. Whether its enabled is determined by the option value; setting the value to enabled or on will enable the component, any other value (typically disabled or off) will disable the component.
The option name is either the fully qualified name of the components or the module/package prefix of the component. The former enables/disables a specific component, while the latter enables/disables any component in the specified package/module.
Consider the following configuration snippet:
[components] trac.ticket.report.ReportModule = disabled webadmin.* = enabled
The first option tells Trac to disable the report module. The second option instructs Trac to enable all components in the webadmin package. Note that the trailing wildcard is required for module/package matching.
See the Plugins page on About Trac to get the list of active components (requires CONFIG_VIEW permissions.)
See also: TracPlugins
Note that prior to Trac r2335 (that applies to 0.9b1 and 0.9b2), you would use a [disabled_components] section instead. See a previous version of this page for the details.
