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).

email_sender	Name of the component implementing IEmailSender. This component is used by the announcer system to send emails. Currently, SmtpEmailSender and SendmailEmailSender are provided.
email_subject_prefix	Text to prepend to subject line of notification emails. If the setting is not defined, then the [$project_name] prefix. If no prefix is desired, then specifying an empty option will disable it.
email_threaded_realms	These are realms with announcements that should be threaded emails. In order for email threads to work, the announcer system needs to give the email recreatable Message-IDs based on the resources in the realm.

The password must be available i.e. provided by running gpg-agent or empty (bad security). On failing to unlock the private key, msg body will get emptied.
ignore_cc_changes	When 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.
joinable_groups	Joinable groups represent 'opt-in' groups that users may freely join. Enter a list of groups (without @) seperated by commas. 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_encoding	Specifies 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.

use_public_cc	Recipients can see email addresses of other CC'ed recipients. If this option is disabled (the default), recipients are put on BCC
use_threaded_delivery	Do message delivery 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. To test, start Python and type 'import threading' to see if it raises an error.
watchable_paths	List of URL paths to allow watching. Globs are supported.
wiki_email_diff	Should a wiki diff be sent with emails?
wiki_email_subject	Format string for the wiki email subject. This is a mini genshi template and it is passed the page, event and action objects.

[attachment]

max_size	Maximum allowed file size (in bytes) 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).

[fullblog]

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)

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)

[wiki]

ignore_missing_pages	Enable/disable highlighting CamelCase links to missing pages (since 0.9).
max_size	Maximum allowed wiki page size in bytes. (since 0.11.2)
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]

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.)

[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.
