The Trac Configuration File

Trac configuration is done by editing the trac.ini config file, located in <projectenv>/conf/trac.ini.

Global Configuration

Since version 0.9, Trac can also read the configuration from a global trac.ini file. These global options will then be merged with the environment-specific options, where local options override global options.

The global configuration is by default localted in $prefix/share/trac/conf/trac.ini. It can be moved to a different location (for example, /etc/trac.ini), but that requires changing the file trac/siteconfig.py which gets created when Trac is installed.

Reference

This is a brief reference of available configuration options.

[account-manager]

account_changes_notify_addresses

List of email addresses that get notified of user changes, ie, new user, password change and delete user.

[attachment]

max_size

Maximum allowed file size (in bytes) for attachments.

262144
max_zip_size

Maximum allowed total size (in bytes) for an attachment list to be downloadable as a .zip. Set this to -1 to disable download as .zip. (since 1.0)

2097152
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.

disabled

[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.

enabled
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/*
hide_properties

Comma-separated list of version control properties to hide from the repository browser.

svk:merge
intermediate_color

(r,g,b) color triple to use for the color corresponding to the intermediate color, if two linear interpolations are used for the color scale (see intermediate_point). If not set, the intermediate color between oldest_color and newest_color will be used.

(no default)
intermediate_point

If set to a value between 0 and 1 (exclusive), this will be the point chosen to set the intermediate_color for interpolating the color value.

(no default)

trac:summary
render_unsafe_content

Whether raw files 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 create a file containing cross-site scripting attacks.

For open repositories where anyone can check-in a file, it is recommended to leave this option disabled.

enabled

[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
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. Note that the trailing wildcard is required for module/package matching.

To view the list of active components, go to the Plugins page on About Trac (requires CONFIG_VIEW permissions).

[intertrac]

This section configures InterTrac prefixes. Options in this section whose name contain a . define aspects of the InterTrac prefix corresponding to the option name up to the .. Options whose name don't contain a . define an alias.

The .url is mandatory and is used for locating the other Trac. This can be a relative URL in case that Trac environment is located on the same server.

The .title information is used for providing a useful tooltip when moving the cursor over an InterTrac link.

Example configuration:

[intertrac]
# -- Example of setting up an alias:
t = trac

# -- Link to an external Trac:
trac.title = Edgewall's Trac for Trac
trac.url = http://trac.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.

trac.log
log_format

Custom logging format.

If nothing is set, the following will be used:

Trac[$(module)s] $(levelname)s: $(message)s

In addition to regular key names supported by the Python logger library one could use:

  • $(path)s the path for the current environment
  • $(basename)s the last path component of the current environment
  • $(project)s the project name

Note the usage of $(...)s instead of %(...)s as the latter form would be interpreted by the ConfigParser itself.

Example: ($(thread)d) Trac[$(basename)s:$(module)s] $(levelname)s: $(message)s

(no default)
log_level

Level of verbosity in log.

Should be one of (CRITICAL, ERROR, WARNING, INFO, DEBUG).

DEBUG

Should be one of (none, file, stderr, syslog, winlog).

none

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:

(no default)
stats_provider

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

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.

[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.

default
restrict_owner

Make the owner field of tickets use a drop-down menu. Be sure to understand the performance implications before activating this option. See Assign-to as Drop-Down List.

Please note that e-mail addresses are not obfuscated in the resulting drop-down menu, so this option should not be used if e-mail addresses must remain protected.

disabled
workflow

Ordered list of workflow controllers to use for ticket actions.

ConfigurableTicketWorkflow

[ticket-custom]

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

[ticket-workflow]

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.

[timeline]

abbreviated_messages

Whether 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.

enabled
changeset_collapse_events

Whether 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.

disabled
changeset_long_messages

Whether 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).

oneliner
ticket_show_component

Enable the display of component of tickets in the timeline. (since 1.1.1)

disabled
ticket_show_details

Enable the display of all ticket changes in the timeline, not only open / close operations.

disabled

[trac]

auto_preview_timeout

Inactivity timeout in seconds after which the automatic wiki preview triggers an update. This option can contain floating-point values. The lower the setting, the more requests will be made to the server. Set this to 0 to disable automatic preview. (since 0.12)

2.0
auto_reload

Automatically reload template files after modification.

disabled
backup_dir

Database backup location

db
base_url

Reference URL for the Trac deployment.

This is the base URL that will be used when producing documents that will be used outside of the web browsing context, like for example when inserting URLs pointing to Trac resources in notification e-mails.

(no default)
database

Database connection string for this project

sqlite:db/trac.db
debug_sql

Show the SQL queries in the Trac log, at DEBUG level.

disabled
default_charset

Charset to be used when in doubt.

utf-8
default_date_format

The date format. Valid options are 'iso8601' for selecting ISO 8601 format, or leave it empty which means the default date format will be inferred from the browser's default language. (since 1.0)

(no default)
default_dateinfo_format

The date information format. Valid options are 'relative' for displaying relative format and 'absolute' for displaying absolute format. (since 1.0)

(no default)
genshi_cache_size

The maximum number of templates that the template loader will cache in memory. 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.

128
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.

(no default)
jquery_location

Location of the jQuery JavaScript library (version 1.11.3).

An empty value loads jQuery from the copy bundled with Trac.

Alternatively, jQuery could be loaded from a CDN, for example: http://code.jquery.com/jquery-1.11.3.min.js, http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.11.3.min.js or https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js.

(since 1.0)

(no default)
jquery_ui_location

Location of the jQuery UI JavaScript library (version 1.11.4).

An empty value loads jQuery UI from the copy bundled with Trac.

Alternatively, jQuery UI could be loaded from a CDN, for example: https://ajax.googleapis.com/ajax/libs/jqueryui/1.11.4/jquery-ui.min.js or http://ajax.aspnetcdn.com/ajax/jquery.ui/1.11.4/jquery-ui.min.js.

(since 1.0)

(no default)
jquery_ui_theme_location

Location of the theme to be used with the jQuery UI JavaScript library (version 1.11.4).

An empty value loads the custom Trac jQuery UI theme from the copy bundled with Trac.

Alternatively, a jQuery UI theme could be loaded from a CDN, for example: https://ajax.googleapis.com/ajax/libs/jqueryui/1.11.4/themes/start/jquery-ui.css or http://ajax.aspnetcdn.com/ajax/jquery.ui/1.11.4/themes/start/jquery-ui.css.

(since 1.0)

(no default)
never_obfuscate_mailto

Never obfuscate mailto: links explicitly written in the wiki, even if show_email_addresses is false or the user doesn't have EMAIL_VIEW permission.

disabled
permission_policies

List of components implementing IPermissionPolicy, in the order in which they will be applied. These components manage fine-grained access control to Trac resources.

ReadonlyWikiPolicy,DefaultPermissionPolicy,LegacyAttachmentPolicy
permission_store

Name of the component implementing IPermissionStore, which is used for managing user and group permissions.

DefaultPermissionStore
request_filters

Ordered list of filters to apply to all requests.

(no default)

Restrict 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.

disabled
show_email_addresses

Show email addresses instead of usernames. If false, email addresses are obfuscated for users that don't have EMAIL_VIEW permission.

disabled
show_full_names

Show full names instead of usernames. (since 1.2)

enabled
show_ip_addresses

Show IP addresses for resource edits (e.g. wiki). Since 1.0.5 this option is deprecated and will be removed in 1.3.1.

disabled
timeout

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

20
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.

disabled
use_chunked_encoding

If enabled, send contents as chunked encoding in HTTP/1.1. Otherwise, send contents with Content-Length header after entire of the contents are rendered. (since 1.0.6)

disabled
use_xsendfile

When true, send a X-Sendfile header and no content when sending files from the filesystem, so that the web server handles the content. This requires a web server that knows how to handle such a header, like Apache with mod_xsendfile or lighttpd. (since 1.0)

disabled
wiki_toolbars

Add a simple toolbar on top of Wiki <textarea>s. (since 1.0.2)

enabled

Enable/disable splitting the WikiPageNames with space characters.

disabled

[components]

(since 0.9)

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

Note that prior to Trac r2335 (that applies to 0.9b1 and 0.9b2), you would use a [disabled_components] section instead. See a previous version of this page for the details.
