The Trac Configuration File
Table of Contents
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.
Global Configuration
In previous versions, the global configuration was by default located in $prefix/share/trac/conf/trac.ini or sometimes /etc/trac/trac.ini depending on the distribution. If you're upgrading, you may want to specify that file to inherit from.
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 = /usr/share/trac/conf/trac.ini
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. |
| allow_delete_account | Allow users to delete their own account. |
| authentication_url | URL of the HTTP authentication service |
| force_passwd_change | Force the user to change password when it's reset. |
| generated_password_length | Length of the randomly-generated passwords created when resetting the password for an account. |
| hash_method | Default hash type of new/updated passwords |
| htdigest_realm | Realm to select relevant htdigest file entries |
| htpasswd_hash_type | Default hash type of new/updated passwords |
| login_attempt_max_count | Lock user account after specified number of login attempts. Value zero means no limit. |
| login_opt_list | Set to True, to switch login page style showing alternative actions in a single listing together. |
| notify_actions | Comma separated list of actions to notify of. Available actions 'new', 'change', 'delete'. |
| password_file | Path to the users file; leave blank to locate the users file by reading svnserve.conf |
| password_format | |
| password_store | |
| persistent_sessions | Allow the user to be remembered across sessions without needing to re-authenticate. This is, user checks a "Remember Me" checkbox and, next time he visits the site, he'll be remembered. |
| phpbb_database | Database URI for the phpBB database to auth against |
| phpbb_hash_prefix | Hash prefix used for phpBB passwords. |
| phpbb_table_prefix | Prefix for phpBB table names. This should be everything before "user" including an underscore if present. |
| refresh_passwd | Re-set passwords on successful authentication. This is most useful to move users to a new password store or enforce new store configuration (i.e. changed hash type), but should be disabled/unset otherwise. |
| reset_password | Set to False, if there is no email system setup. |
| user_lock_max_time | Limit user account lock time to specified time (seconds). This is relevant only with user_lock_time_progression > 1. |
| user_lock_time | Drop user account lock after specified time (seconds). Value zero means unlimited lock time. |
| user_lock_time_progression | Extend user account lock time incrementally. This is based on logarithmic calculation and decimal numbers accepted: Value '1' means constant lock time per failed login attempt. Value '2' means double locktime after 2nd lock activation, four times the initial locktime after 3rd, and so on. |
| username_char_blacklist | Always exclude some special characters from usernames. This is enforced upon new user registration. |
| verify_email | Verify the email address of Trac users. |
[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.

| oldest_color | (r,g,b) color triple to use for the color corresponding to the oldest color, for the color scale used in blame or the browser age column if color_scale is enabled. (since 0.11) |
| oneliner_properties | Comma-separated list of version control properties to render as oneliner wiki content in the repository browser. (since 0.11) |
| 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 (which is the default). |
| wiki_properties | Comma-separated list of version control properties to render as wiki content in the repository browser. (since 0.11) |
[changeset]
| max_diff_bytes | Maximum total size in bytes of the modified files (their old size plus their new size) for which the changeset view will attempt to show the diffs inlined (since 0.10). |

| 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 library (see http://docs.python.org/lib/node422.html), 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 (since 0.10.5) |

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) |

| split_page_names | Enable/disable splitting the WikiPageNames with space characters (since 0.10). |
[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
[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.
[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 (which is also the default):
closed = closed closed.order = 0 # sequence number in the progress bar closed.query_args = group=resolution # optional extra param for the query closed.overall_completion = true # count for overall completion active = * # one catch-all group is allowed active.order = 1 active.css_class = open # CSS class for this interval
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>
[svn:externals]
(since 0.11)
The TracBrowser for Subversion can interpret the svn:externals property of folders out of the box. However, if those externals are not using the http: protocol, or if a link to a different repository browser (such another Trac or ViewVC) is desired, then Trac needs to be able to map an external prefix to this other URL.
This mapping is done in the [svn:externals] section of the TracIni
Example:
[svn:externals] http://theirserver.org/svn/eng-soft http://ourserver/viewvc/svn/$path/?pathrev=25914 svn://anotherserver.com/tools_repository http://ourserver/trac/support/browser/$path?rev=$rev
With the above, the svn://anotherserver.com/tools_repository/tags/1.1/tools external will be mapped to http://ourserver/trac/support/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).
