wiki:TracIni

Version 6 (modified by trac, 2 months ago) (diff)

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 a complete environment reload and flush its caches 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 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, refresh your modifications when you upgrade to a new version of Trac. The preferred way to perform TracInterfaceCustomization is 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.

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.

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/*

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.

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).

See also: TracPlugins

[extra-permissions]

This section provides a way to add arbitrary permissions to a Trac environment. This can be useful for adding new permissions to use for workflow actions, for example.

To add new permissions, create a new section [extra-permissions] in your trac.ini. Every entry in that section defines a meta-permission and a comma-separated list of permissions. For example:

[extra-permissions]
EXTRA_ADMIN = EXTRA_VIEW, EXTRA_MODIFY, EXTRA_DELETE

This entry will define three new permissions EXTRA_VIEW, EXTRA_MODIFY and EXTRA_DELETE, as well as a meta-permissions EXTRA_ADMIN that grants all three permissions.

The permissions are created in upper-case characters regardless of the casing of the definitions in trac.ini. For example, the definition extra_view would create the permission EXTRA_VIEW.

If you don't want a meta-permission, start the meta-name with an underscore (_):

[extra-permissions]
_perms = EXTRA_VIEW, EXTRA_MODIFY

This way you will be able to track outgoing links. Outbound link tracking must be enabled for external links to be tracked.

/external/
outbound_link_tracking

Disabling this option will turn off the tracking of outbound links. It's recommended not to disable this option unless you're a privacy advocate (now why would you be using Google Analytics in the first place?) or it's causing some kind of weird issue.

enabled
tracking_domain_name

If you're tracking multiple subdomains with the same Google Analytics profile, like what's talked about in:

https://www.google.com/support/googleanalytics/bin/answer.py?answer=55524

enter your main domain here. For more info, please visit the previous link.

(no default)
uid

Google Analytics' UID. The UID is needed for Google Analytics to log your website stats. Your UID can be found by looking in the JavaScript? Google Analytics gives you to put on your page. Look for your UID in between var pageTracker = _gat._getTracker("UA-111111-11"); in the javascript. In this example you would put UA-11111-1 in the UID box.

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.

[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.

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.

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.
