The Trac Configuration File
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). |
[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) |
| downloadable_paths | List of repository paths that can be downloaded.
Leave the 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)
(since 0.10) |
| hide_properties | Comma-separated list of version control properties to hide from
the repository browser.
(since 0.9) |
| 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) |
| intermediate_point | If set to a value between 0 and 1 (exclusive), this will be the
point chosen to set the intermediate_color for interpolating
the color value.
(since 0.11) |
| 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) |
| 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) |
| oneliner_properties | Comma-separated list of version control properties to render
as oneliner wiki content in the repository browser.
(since 0.11) |
| 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). |
| wiki_properties | Comma-separated list of version control properties to render
as wiki content in the repository browser.
(since 0.11) |
[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). |
| max_diff_files | Maximum number of modified files for which the changeset view will
attempt to show the diffs inlined (since 0.10). |

pre-formatted text. |
| alt | Alternative text for the header logo. |
| height | Height of the header logo image in pixels. |

directory of the environment plugins, with this one taking
precedence.

| 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
library (see http://docs.python.org/lib/node422.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) |

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

(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.
