The Trac Configuration File
Table of Contents
Trac is configured through the trac.ini file, located in the <projectenv>/conf directory. The trac.ini configuration file and its parent directory should be writable by the web server.
Trac monitors the timestamp of the file to trigger an environment reload when the timestamp changes. Most changes to the configuration will be 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.
Global Configuration
Configuration can be shared among environments using one or more global configuration files. Options in the global configuration will be merged with the environment-specific options, with local options overriding global options. The global configuration file is specified as follows:
[inherit] file = /path/to/global/trac.ini
Multiple files can be specified using a comma-separated list. Non-absolute paths are relative to the Environment conf directory.
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 specify --inherit 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 in the global file.
There are three more options in the [inherit] section, templates_dir for sharing global templates, htdocs_dir for sharing global htdocs and plugins_dir, for sharing plugins. Those options can 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, refresh your modifications when you upgrade to a new version of Trac. The preferred way to perform TracInterfaceCustomization is to write a custom plugin doing an appropriate ITemplateStreamFilter transformation.
Reference for settings
This is a reference of available configuration options, and their default settings.
Documentation improvements should be discussed on the trac-dev mailing list or described in a ticket. Even better, submit a patch against the docstrings in the code.

[components]
Enable or disable components provided by Trac and plugins.
The component to enable/disable is specified by the option name.
The enabled state 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 component 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 acct_mgr.* = enabled
The first option tells Trac to disable the
report module.
The second option instructs Trac to enable all components in
the acct_mgr package. The trailing wildcard is required for
module/package matching.
To view the list of active components, go to the Plugins
section of About Trac (requires CONFIG_VIEW
permission).

[intertrac]
This section configures InterTrac prefixes. Option names in
this section that contain a . are of the format
<name>.<attribute>. Option names that don't contain a . define

The .url attribute is mandatory and is used for locating the
other Trac. This can be a relative path when the other Trac
environment is located on the same server.
The .title attribute is used for generating a tooltip when the
cursor is hovered over an InterTrac link.

can be disabled by setting the value of the navigation item to
disabled.
The following example renames the link to WikiStart to Home, links the View Tickets entry to a specific report and disables the Search entry.
[mainnav] wiki.label = Home tickets.href = /report/24 search = disabled
See TracNavigation for more details.
[metanav]
Configures the meta navigation
entries, which by default are Login, Logout, Preferences,
Help/Guide and About Trac. The allowed attributes are the
same as for [mainnav]. Additionally, a special entry is supported -
logout.redirect is the page the user sees after hitting the logout
button. For example:
[metanav] logout.redirect = wiki/Logout

stats_provider |
Name of the component implementing | DefaultTicketGroupStatsProvider |
[milestone-groups]
As the workflow for tickets is now configurable, there can be many ticket states, and simply displaying closed tickets vs. all the others is maybe not appropriate in all cases. This section enables one to easily create groups of states that will be shown in different colors in the milestone progress bar.
Note that the groups can only be based on the ticket status, nothing else. In particular, it's not possible to distinguish between different closed tickets based on the resolution.
Example configuration with three groups, closed, new and active (the default only has closed and active):
# the 'closed' group correspond to the 'closed' tickets
closed = closed
# .order: sequence number in the progress bar
closed.order = 0
# .query_args: optional parameters for the corresponding
# query. In this example, the changes from the
# default are two additional columns ('created' and
# 'modified'), and sorting is done on 'created'.
closed.query_args = group=resolution,order=time,col=id,col=summary,col=owner,col=type,col=priority,col=component,col=severity,col=time,col=changetime
# .overall_completion: indicates groups that count for overall
# completion percentage
closed.overall_completion = true
new = new
new.order = 1
new.css_class = new
new.label = new
# Note: one catch-all group for other statuses is allowed
active = *
active.order = 2
# .css_class: CSS class for this interval
active.css_class = open
# .label: displayed label for this group
active.label = in progress
The definition consists in a comma-separated list of accepted status. Also, '*' means any status and could be used to associate all remaining states to one catch-all group.
The CSS class can be one of: new (yellow), open (no color) or
closed (green). Other styles can easily be added using custom
CSS rule: table.progress td.<class> { background: <color> }
to a site/style.css file
for example.

Configure Error Reporting
The error reporting page has a Create button for reporting issues. The site to which issues are reported depends on the configuration of the Trac site and the user’s permissions.
If the user doesn’t possess TRAC_ADMIN, the site to which a user is directed to create a ticket is determined by the [trac] admin_trac_url setting:
- If empty, there will be no Create button.
- If set to the default value (
.), the ticket will be created on the site which the error occurred. - Otherwise the ticket will be created at the site pointed
to by
admin_trac_url.
If [project] admin is not empty, the administrator's email address will be rendered on the error page.
If the user possesses TRAC_ADMIN, the Create button will direct the user to report the issue on trac.edgewall.org. If the error was generated in a plugin, the error will be reported to the project URL provided that the plugin author has included the project URL in the plugin installation data. The user possessing TRAC_ADMIN also sees a traceback and system information on the error page.
