Version 5 (modified by trac, 5 years ago) (diff)

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).

Reference for settings

This is a brief reference of available configuration options, and their default settings.

[account-manager]

account_changes_notify_addresses

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

[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).

[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

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.

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.

DONE,DEBUGGED,FIXED,REVIEWED
fixme_phrases

A list of attentional phrases or single words, separated by comma (,) that will be highlighted to catch attention. Any delimiter ():<> adjacent to a phrase will not be presented. (i.e. do not include any of these delimiters in this list). This makes it possible to naturally write, for example, FIXME: in a wiki text, but view the phrase highlighted without the colon (:) which would not look natural. Use the ShowPhrases macro to show a list of currently defined phrases.

[wikiextras-smileys]

The set of smileys is configurable by providing associations between icon names and wiki keywords. A default set of icons and keywords is defined, which can be revoked one-by-one (_remove) or all at once (_remove_defaults).

Example:

[wikiextras-smileys]
_remove_defaults = true
_remove = :-( :(
smiley = :-) :)
smiley-wink = ;-) ;)
clock = (CLOCK) (TIME)
calendar-month = (CALENDAR) (DATE)
chart = (CHART)
document-excel = (EXCEL)
document-word = (WORD)
eye = (EYE)
new = (NEW)
tick = (TICK)

Keywords are space-separated!

A smiley can also be removed by associating its icon with nothing:

smiley =

Use the ShowSmileys macro to find out the current set of icons and keywords.

_remove

Space-separated(!) list of keywords that shall not be interpreted as smileys (even if defined in this section).

(no default)
_remove_defaults

Set to true to remove all default smileys.

disabled

[wikiextras-symbols]

The set of symbols is configurable by providing associations between symbols and wiki keywords. A default set of symbols and keywords is defined, which can be revoked one-by-one (_remove) or all at once (_remove_defaults).

Example:

[wikiextras-symbols]
_remove_defaults = true
_remove = <- ->
&laquo; = <<
&raquo; = >>
&sum; = (SUM)
&hearts; = <3

Keywords are space-separated!

A symbol can also be removed by associating it with no keyword:

&larr; =

Use the ShowSymbols macro to find out the current set of symbols and keywords.

_remove

Space-separated(!) list of keywords that shall not be interpreted as symbols (even if defined in this section).

(no default)

Reference for special sections

  1. [components]
  2. [extra-permissions]
  3. [milestone-groups]
  4. [repositories]
  5. [svn:externals]
  6. [ticket-custom]
  7. [ticket-workflow]

[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.)

See also: TracPlugins

[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.
