The Trac Configuration File

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.

[account-manager]

account_changes_notify_addresses	List of email addresses that get notified of user changes, ie, new user, password change and delete user.
allow_delete_account	Allow users to delete their own account.
cookie_refresh_pct	Persistent sessions randomly get a new session cookie ID with likelihood in percent per work hour given here (zero equals to never) to decrease vulnerability of long-lasting sessions.
environ_auth_overwrite	Whether environment variable REMOTE_USER should get overwritten after processing login form input. Otherwise it will only be set, if unset at the time of authentication.
force_passwd_change	Force the user to change password when it's reset.
generated_password_length	Length of the randomly-generated passwords created when resetting the password for an account.
htpasswd_file	Path relative to Trac environment or full host machine path to password file
htpasswd_hash_type	Default hash type of new/updated passwords
login_opt_list	Set to True, to switch login page style showing alternative actions in a single listing together.

password_format	Legacy option, deprecated since acct_mgr-0.1.2
password_store	Ordered list of password stores, queried in turn.
persistent_sessions	Allow the user to be remembered across sessions without needing to re-authenticate. This is, user checks a "Remember Me" checkbox and, next time he visits the site, he'll be remembered.
refresh_passwd	Re-set passwords on successful authentication. This is most useful to move users to a new password store or enforce new store configuration (i.e. changed hash type), but should be disabled/unset otherwise.
register_basic_token	A string required as input to pass verification.
register_check	Ordered list of IAccountRegistrationInspector's to use for registration checks.
reset_password	Set to False, if there is no email system setup.

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)

Name of the component implementing ITicketGroupStatsProvider, which is used to collect statistics on groups of tickets for display in the roadmap views.

[search]

default_disabled_filters

Specifies which search filters should be disabled by default on the search page. This will also restrict the filters for the quick search function. The filter names defined by default components are: wiki, ticket, milestone and changeset.

The default value of 0 makes the cookie expire at the end of the browsing session. (since 0.12)
auth_cookie_path	Path for the authentication cookie. Set this to the common base path of several Trac instances if you want them to share the cookie. (since 0.12)

default_timezone	The default timezone to use
genshi_cache_size	The maximum number of templates that the template loader will cache in memory. The default value is 128. You may want to choose a higher value if your site uses a larger number of templates, and you have enough memory to spare, or you can reduce it if you are short on memory.
htdocs_location	Base URL for serving the core static resources below /chrome/common/. It can be left empty, and Trac will simply serve those resources itself. Advanced users can use this together with trac-admin ... deploy <deploydir> to allow serving the static resources for Trac directly from the web server. Note however that this only applies to the <deploydir>/htdocs/common directory, the other deployed resources (i.e. those from plugins) will not be made available this way and additional rewrite rules will be needed in the web server.

Defaults to the DefaultPermissionPolicy? (pre-0.11 behavior) and LegacyAttachmentPolicy? (map ATTACHMENT_* permissions to realm specific ones)
permission_store	Name of the component implementing IPermissionStore, which is used for managing user and group permissions.
pg_dump_path	Location of pg_dump for Postgres database backups
repository_dir	Path to the default repository. This can also be a relative path (since 0.11). This option is deprecated, and repositories should be defined in the repositories section, or using the "Repositories" admin panel. (since 0.12)
repository_sync_per_request	List of repositories that should be synchronized on every page request. Leave this option empty if you have set up post-commit hooks calling trac-admin $ENV changeset added on all your repositories (recommended). Otherwise, set it to a comma-separated list of repository names. Note that this will negatively affect performance, and will prevent changeset listeners from receiving events from the repositories specified here. The default is to synchronize the default repository, for backward compatibility. (since 0.12)
repository_type	Default repository connector type. (since 0.10) This is also used as the default repository type for repositories defined in TracIni#repositories-section repositories or using the "Repositories" admin panel. (since 0.12)

timeout	Timeout value for database connection, in seconds. Use '0' to specify no timeout. (Since 0.11)
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)

[versioncontrol]

allowed_repository_dir_prefixes

Comma-separated list of allowed prefixes for repository directories when adding and editing repositories in the repository admin panel. If the list is empty, all repository directories are allowed. (since 0.12.1)

[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.

See the Plugins page on About Trac to get the list of active components (requires CONFIG_VIEW permissions.)

See also: TracPlugins

[extra-permissions]

(since 0.12)

Custom additional permissions can be defined in this section when ExtraPermissionsProvider? is enabled.

[milestone-groups]

(since 0.11)

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.

Example configuration (the default only has closed and active):

closed = closed
# sequence number in the progress bar
closed.order = 0
# optional extra param for the query (two additional columns: created and modified and sort 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
# indicates groups that count for overall completion percentage
closed.overall_completion = true

new = new
new.order = 1
new.css_class = new
new.label = new

# one catch-all group is allowed
active = *
active.order = 2
# CSS class for this interval
active.css_class = open
# 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). New styles can easily be added using the following selector: table.progress td.<class>

[repositories]

(since 0.12 multirepos)

One of the alternatives for registering new repositories is to populate the [repositories] section of the trac.ini.

This is especially suited for setting up convenience aliases, short-lived repositories, or during the initial phases of an installation.

See TracRepositoryAdmin for details about the format adopted for this section and the rest of that page for the other alternatives.

[svn:externals]

(since 0.11)

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.

[ticket-custom]

In this section, you can define additional fields for tickets. See TracTicketsCustomFields for more details.

[ticket-workflow]

(since 0.11)

The workflow for tickets is controlled by plugins. By default, there's only a ConfigurableTicketWorkflow component in charge. That component allows the workflow to be configured via this section in the trac.ini file. See TracWorkflow for more details.
