The Trac Configuration File
[Note To Editors] Please discuss documentation changes in the #Discussion section. Even better, send us documentation patches? against the code (i.e. where the configuration entries are documented), either on Trac-dev or on new tickets.
Table of Contents
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 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, 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.

| 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). | false |
[browser]
| color_scale | Enable colorization of the age column. This uses the same color scale as the source code annotation: blue is older, red is newer. (since 0.11) | enabled |
| downloadable_paths | List of repository paths that can be downloaded. Leave this option empty if you want to disable all downloads, otherwise set it to a comma-separated list of authorized paths (those paths are glob patterns, i.e. "*" can be used as a wild card). In a multi-repository environment, the path must be qualified with the repository name if the path does not point to the default repository (e.g. /reponame/trunk). Note that a simple prefix matching is performed on the paths, so aliases won't get automatically resolved. (since 0.10) | /trunk, /branches/*, /tags/* |
| hide_properties | Comma-separated list of version control properties to hide from the repository browser. (since 0.9) | svk:merge |
| intermediate_color | (r,g,b) color triple to use for the color corresponding to the intermediate color, if two linear interpolations are used for the color scale (see intermediate_point). If not set, the intermediate color between oldest_color and newest_color will be used. (since 0.11) | (no default) |

| newest_color | (r,g,b) color triple to use for the color corresponding to the newest color, for the color scale used in blame or the browser age column if color_scale is enabled. (since 0.11) | (255, 136, 136) |
| oldest_color | (r,g,b) color triple to use for the color corresponding to the oldest color, for the color scale used in blame or the browser age column if color_scale is enabled. (since 0.11) | (136, 136, 255) |
| oneliner_properties | Comma-separated list of version control properties to render as oneliner wiki content in the repository browser. (since 0.11) | trac:summary |
| render_unsafe_content | Whether raw files 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 create a file containing cross-site scripting attacks. For open repositories where anyone can check-in a file, it is recommended to leave this option disabled (which is the default). | false |
| wiki_properties | Comma-separated list of version control properties to render as wiki content in the repository browser. (since 0.11) | trac:description |
[changeset]
| max_diff_bytes | Maximum total size in bytes of the modified files (their old size plus their new size) for which the changeset view will attempt to show the diffs inlined (since 0.10). | 10000000 |
| max_diff_files | Maximum number of modified files for which the changeset view will attempt to show the diffs inlined (since 0.10). | 0 |
| wiki_format_messages | Whether wiki formatting should be applied to changeset messages. If this option is disabled, changeset messages will be rendered as pre-formatted text. | true |
[components]
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.
To view the list of active components, go to the Plugins page on About Trac (requires CONFIG_VIEW permissions).

[header_logo]
| alt | Alternative text for the header logo. | (please configure the [header_logo] section in trac.ini) |
| height | Height of the header logo image in pixels. | -1 |
| link | URL to link to, from the header logo. | (no default) |
| 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. | site/your_project_logo.png |
| width | Width of the header logo image in pixels. | -1 |
[inherit]
| htdocs_dir | Path to the shared htdocs directory. Static resources in that directory are mapped to /chrome/shared under the environment URL, in addition to common and site locations. This can be useful in site.html for common interface customization of multiple Trac environments. (since 1.0) | (no default) |
| 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) | (no default) |
| 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) | (no default) |
[intertrac]
This section configures InterTrac prefixes. Options in this section whose name contain a "." define aspects of the InterTrac prefix corresponding to the option name up to the ".". Options whose name don't contain a "." define an alias.
The .url is mandatory and is used for locating the other Trac. This can be a relative URL in case that Trac environment is located on the same server.
The .title information is used for providing a useful tooltip when moving the cursor over an InterTrac link.
The .compat option can be used to activate or disable a compatibility mode:
- If the targeted Trac is running a version below 0.10 (r3526 to be precise), then it doesn't know how to dispatch an InterTrac link, and it's up to the local Trac to prepare the correct link. Not all links will work that way, but the most common do. This is called the compatibility mode, and is false by default.
- If you know that the remote Trac knows how to dispatch InterTrac links, you can explicitly disable this compatibility mode and then any TracLinks can become InterTrac links.
Example configuration:
[intertrac] # -- Example of setting up an alias: t = trac # -- Link to an external Trac: trac.title = Edgewall's Trac for Trac trac.url = http://trac.edgewall.org
[interwiki]
Every option in the [interwiki] section defines one InterWiki prefix. The option name defines the prefix. The option value defines the URL, optionally followed by a description separated from the URL by whitespace. Parametric URLs are supported as well.
Example:
[interwiki] MeatBall = http://www.usemod.com/cgi-bin/mb.pl? PEP = http://www.python.org/peps/pep-$1.html Python Enhancement Proposal $1 tsvn = tsvn: Interact with TortoiseSvn
[logging]

| 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) | (no default) |
| log_level | Level of verbosity in log. Should be one of (CRITICAL, ERROR, WARN, INFO, DEBUG). | DEBUG |

| timeout | Timeout value for database connection, in seconds. Use '0' to specify no timeout. (Since 0.11) | 20 |
| 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) | disabled |
| use_xsendfile | When true, send a X-Sendfile header and no content when sending files from the filesystem, so that the web server handles the content. This requires a web server that knows how to handle such a header, like Apache with mod_xsendfile or lighttpd. (since 1.0) | false |

| wide_toc | Right aligned boxes with table of contents, produced by the PageOutline macro, are either as wide as ordinary right aligned boxes (true) or narrow (false). | false |
[wikiextras-smileys]
The set of smileys is configurable by providing associations between icon names and wiki keywords. A default set of icons and keywords is defined, which can be revoked one-by-one (_remove) or all at once (_remove_defaults).
Example:
[wikiextras-smileys] _remove_defaults = true _remove = :-( :( smiley = :-) :) smiley-wink = ;-) ;) clock = (CLOCK) (TIME) calendar-month = (CALENDAR) (DATE) chart = (CHART) document-excel = (EXCEL) document-word = (WORD) eye = (EYE) new = (NEW) tick = (TICK)
