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 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]
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). |
hide_properties | List of subversion properties to hide from the repository browser (since 0.9) |
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) |
[changeset]
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. |
max_diff_files | Maximum number of modified files for which the changeset view will attempt to show the diffs inlined (since 0.10). |

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) |
log_file | If log_type is file, this should be a path to the log-file. |

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) |

[tracbzr]
include_sideline_changes | Include sideline changes in the list of changes. This option controls whether sideline changes (i.e. changes with dotted revision numbers only) are included in the list of changes as reported by the timeline view. Note that there might be other plugins using that information as well, so there might be other components beside the timeline view that get affected by this setting. Defaults to True. |
primary_branches | Ordered list of primary branches. These will be listed first in the Branches macro. When viewing the timeline, each changeset will be associated with the first primary branch that contains it. The value is a comma separated list of globs, as used by the fnmatch module. An empty list element can be used to denote the branch at the root of the repository. Defaults to 'trunk'. |

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). |

[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.)

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.
