The Trac Configuration File

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.

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 two more options in the [inherit] section, templates_dir for sharing global templates 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.

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.

(no default)
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.

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

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

disabled
wiki_properties

Comma-separated list of version control properties to render as wiki content in the repository browser.

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).

[header_logo]

alt

Alternative text for the header logo.

(please configure the [header_logo] section in trac.ini)
height

Height of the header logo image in pixels.

-1
src

URL of the image to use as header logo. It can be absolute, server relative or relative.

If relative, it is relative to one of the /chrome locations: site/your-logo.png if your-logo.png is located in the htdocs folder within your TracEnvironment; common/your-logo.png if your-logo.png is located in the folder mapped to the htdocs_location URL. Only specifying your-logo.png is equivalent to the latter.

site/your_project_logo.png
width

Width of the header logo image in pixels.

-1

[http-headers]

Headers to be added to the HTTP request. (since 1.2.3)

The header name must conform to RFC7230 and the following reserved names are not allowed: content-type, content-length, location, etag, pragma, cache-control, expires.

[inherit]

htdocs_dir

Path to the shared htdocs directory.

Static resources in that directory are mapped to /chrome/shared under the environment URL, in addition to common and site locations.

This can be useful in site.html for common interface customization of multiple Trac environments.

Non-absolute paths are relative to the Environment conf directory. (since 1.0)

(no default)
plugins_dir

Path to the shared plugins directory.

Plugins in that directory are loaded in addition to those in the directory of the environment plugins, with this one taking precedence.

Non-absolute paths are relative to the Environment conf directory.

Templates in that directory are loaded in addition to those in the environments templates directory, but the latter take precedence.

Non-absolute paths are relative to the Environment conf directory.

(no default)

[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.

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]

log_file

If log_type is file, this should be a path to the log-file. Relative paths are resolved relative to the log directory of the environment.

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
log_type

Logging facility to use.

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:

[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 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.

If native, substitute with the native EOL marker on the server. Otherwise, if LF, CRLF or CR, substitute with the specified EOL marker.

(since 1.0.2)

native
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/*, /projectAlpha/tags/A-1.0, /projectAlpha/tags/A-v1.1

[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.

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.

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.

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.

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.

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
