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 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 = /usr/share/trac/conf/trac.ini

Note that you can also specify a global option file when creating a new project, by adding the option --inherit=/path/to/global/options to trac-admin's initenv command. If 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.

Reference

This is a brief reference of available configuration options.

[announcer]

admit_domainsComma-separated list of domains that should be considered as valid for email addresses (such as localdomain)
always_notify_component_ownerWhether or not to notify the owner of the ticket's component.

email_address_resolversComma seperated list of email resolver components in the order they will be called. If an email address is resolved, the remaining resolvers will no be called.
ignore_cc_changesWhen true, the system will not send out announcement events if the only field that was changed was CC. A change to the CC field that happens at the same as another field will still result in an event being created.
ignore_domainsComma-separated list of domains that should not be considered part of email addresses (for usernames with Kerberos domains)
joinable_groupsJoinable groups represent 'opt-in' groups that users may freely join. The name of the groups should be a simple alphanumeric string. By adding the group name preceeded by @ (such as @sec for the sec group) to the CC field of a ticket, everyone in that group will receive an announcement when that ticket is changed.
mime_encodingSpecifies the MIME encoding scheme for emails. Valid options are 'base64' for Base64 encoding, 'qp' for Quoted-Printable, and 'none' for no encoding. Note that the no encoding means that non-ASCII characters in text are going to cause problems with notifications (since 0.10).
never_notify_updaterThe never_notify_updater option mimics the plugin of the same name in the notification section, except users can opt-out in their preferences. Used only if LegacyTicketSubscriber? is enabled.

use_threaded_deliveryIf true, the actual delivery of the message will occur in a separate thread. Enabling this will improve responsiveness for requests that end up with an announcement being sent over email. It requires building Python with threading support enabled-- which is usually the case.

[timeline]

abbreviated_messagesWhether wiki-formatted event messages should be truncated or not. This only affects the default rendering, and can be overriden by specific event providers, see their own documentation. (Since 0.11)
changeset_collapse_eventsWhether consecutive changesets from the same author having exactly the same message should be presented as one event. That event will link to the range of changesets in the log view. (since 0.11)
changeset_long_messagesWhether wiki-formatted changeset messages should be multiline or not. If this option is not specified or is false and wiki_format_messages is set to true, changeset messages will be single line only, losing some formatting (bullet points, etc).
changeset_show_filesNumber of files to show (-1 for unlimited, 0 to disable). This can also be location, for showing the common prefix for the changed files. (since 0.11).
default_daysbackDefault number of days displayed in the Timeline, in days. (since 0.9.)
max_daysbackMaximum number of days (-1 for unlimited) displayable in the Timeline. (since 0.11)
newticket_formatterWhich formatter flavor (e.g. 'html' or 'oneliner') should be used when presenting the description for new tickets. If 'oneliner', the [timeline] abbreviated_messages option applies. (since 0.11).
ticket_show_detailsEnable the display of all ticket changes in the timeline, not only open / close operations (since 0.9).

mysqldump_pathLocation of mysqldump for MySQL database backups
never_obfuscate_mailtoNever obfuscate mailto: links explicitly written in the wiki, even if show_email_addresses is false or the user has not the EMAIL_VIEW permission (since 0.11.6).
permission_policiesList of components implementing IPermissionPolicy, in the order in which they will be applied. These components manage fine-grained access control to Trac resources. Defaults to the DefaultPermissionPolicy? (pre-0.11 behavior) and LegacyAttachmentPolicy? (map ATTACHMENT_* permissions to realm specific ones)

pg_dump_pathLocation of pg_dump for Postgres database backups
repository_dirPath to local repository. This can also be a relative path (since 0.11).
repository_typeRepository connector type. (since 0.10)
request_filtersOrdered list of filters to apply to all requests (since 0.10).
secure_cookiesRestrict cookies to HTTPS connections. When true, set the secure flag on all cookies so that they are only sent to the server on HTTPS connections. Use this if your Trac instance is only accessible through HTTPS. (since 0.11.2)
show_email_addressesShow email addresses instead of usernames. If false, we obfuscate email addresses (since 0.11).
show_ip_addressesShow IP addresses for resource edits (e.g. wiki). (since 0.11.3).
timeoutTimeout value for database connection, in seconds. Use '0' to specify no timeout. (Since 0.11)
use_base_url_for_redirectOptionally 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)

[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.)

[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.

[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)
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 
closed.overall_completion = truepercentage

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>

[svn:externals]

(since 0.11)

The TracBrowser for Subversion can interpret the svn:externals property of folders out of the box. However, if those externals are not using the http: or https: protocol, or if a link to a different repository browser such as another Trac or  ViewVC is desired, then Trac needs to be able to map an external prefix to this other 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.
