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.

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. | /trunk,/branches/*,/tags/* |

max_diff_files | Maximum number of modified files for which the changeset view will attempt to show the diffs inlined. | 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. | enabled |
[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
an alias.
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.
Example configuration:
[intertrac] # -- Example of setting up an alias: t = trac # -- Link to an external Trac: genshi.title = Edgewall's Trac for Genshi genshi.url = https://genshi.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]

[mainnav]
Configures the main navigation bar, which by default contains Wiki, Timeline, Roadmap, Browse Source, View Tickets, New Ticket, Search and Admin.
The label, href, and order attributes can be specified. Entries
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
See TracNavigation for more details.
[milestone]
default_group_by | Default field to use for grouping tickets in the grouped progress bar. (since 1.2) | component |
default_retarget_to | Default milestone to which tickets are retargeted when closing or deleting a milestone. (since 1.1.2) | (no default) |
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.

tags | Comma separated list of paths categorized as tags.
If a path ends with '*', then all the directory entries found below
that path will be included.
Example: | tags/* |
[svn:externals]
The TracBrowser for Subversion can interpret the svn:externals
property of folders. By default, it only turns the URLs into links as
Trac can't browse remote repositories.
However, if you have another Trac instance (or an other repository
browser like ViewVC) configured to browse the
target repository, then you can instruct Trac which other repository
browser to use for which external URL. This mapping is done in the
[svn:externals] section of the TracIni.
Example:
[svn:externals] 1 = svn://server/repos1 http://trac/proj1/browser/$path?rev=$rev 2 = svn://server/repos2 http://trac/proj2/browser/$path?rev=$rev 3 = http://theirserver.org/svn/eng-soft http://ourserver/viewvc/svn/$path/?pathrev=25914 4 = svn://anotherserver.com/tools_repository http://ourserver/tracs/tools/browser/$path?rev=$rev
With the above, the
svn://anotherserver.com/tools_repository/tags/1.1/tools external will
be mapped to http://ourserver/tracs/tools/browser/tags/1.1/tools?rev=
(and rev will be set to the appropriate revision number if the
external additionally specifies a revision, see the
SVN Book on externals for more details).
Note that the number used as a key in the above section is purely used as a place holder, as the URLs themselves can't be used as a key due to various limitations in the configuration file parser.
Finally, the relative URLs introduced in Subversion 1.5 are not yet supported.

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.
