The Trac Configuration File
Table of Contents
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.
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.
List of email addresses that get notified of user changes, ie, new user, password change and delete user.
Maximum allowed file size (in bytes) for attachments.
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)
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 (which is the default).
select fields to autocomplement
Resource names that match this pattern will not be added to the breadcrumbs trail.
Text label to show before breadcrumb list. If empty, 'Breadcrumbs:' is used as default.
Indicates maximum number of breadcrumbs to store per user.
List of URL paths to allow breadcrumb tracking. Globs are supported.

Comma-separated list of version control properties to render as wiki content in the repository browser.
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.
To view the list of active components, go to the Plugins page on About Trac (requires CONFIG_VIEW 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
Option for a default naming scheme for new posts. The string can include substitution markers for time (UTC) and user: %Y=year, %m=month, %d=day, %H=hour, %M=minute, %S=second, $USER. Example template string: %Y/%m/%d/my_topic
Ability to specify a list of month names for display in groupings. If empty it will make a list from default locale setting. Enter list of 12 months like: month_names = January, February, ..., December
Option to specify how many recent posts to display on the front page of the Blog (and RSS feeds).
When using the Blog as a personal blog (only one author), setting to 'True' will disable the display of 'Browse by author:' in sidebar, and also removes various author links and references.

Only specifying your-logo.png is equivalent to the latter.
Width of the header logo image in pixels.
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.
Path to the shared plugins directory.

Path to the shared templates directory.
Templates in that directory are loaded in addition to those in the environments templates directory, but the latter take precedence.
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.
The .compat option can be used to activate or disable a compatibility mode:
- If the targeted Trac is running a version below 0.10 (r3526 to be precise), then it doesn't know how to dispatch an InterTrac link, and it's up to the local Trac to prepare the correct link. Not all links will work that way, but the most common do. This is called the compatibility mode, and is false by default.
- If you know that the remote Trac knows how to dispatch InterTrac links, you can explicitly disable this compatibility mode and then any TracLinks can become InterTrac links.
[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
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.
[interwiki] MeatBall = http://www.usemod.com/cgi-bin/mb.pl? PEP = http://www.python.org/peps/pep-$1.html Python Enhancement Proposal $1 tsvn = tsvn: Interact with TortoiseSvn
If log_type is file, this should be a path to the log-file. Relative paths are resolved relative to the log directory of the environment.
Custom logging format.
If nothing is set, the following will be used:
Trac[$(module)s] $(levelname)s: $(message)s
In addition to regular key names supported by the Python logger library (see http://docs.python.org/library/logging.html), one could use:
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
Level of verbosity in log.
Should be one of (CRITICAL, ERROR, WARN, INFO, DEBUG).

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.
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-1.7.2.min.js, http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.7.2.min.js or https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js.

This option is deprecated, and repositories should be defined in the repositories section, or using the "Repositories" admin panel. (since 0.12)
List of repositories that should be synchronized on every page request.
Leave this option empty if you have set up post-commit hooks calling trac-admin $ENV changeset added on all your repositories (recommended). Otherwise, set it to a comma-separated list of repository names. Note that this will negatively affect performance, and will prevent changeset listeners from receiving events from the repositories specified here. The default is to synchronize the default repository, for backward compatibility. (since 0.12)
Default repository connector type. (since 0.10)
This is also used as the default repository type for repositories defined in TracIni#repositories-section repositories or using the "Repositories" admin panel. (since 0.12)

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. (since 0.11.2)
Show email addresses instead of usernames. If false, email addresses are obfuscated for users that don't have EMAIL_VIEW permission. (since 0.11)
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. (since 0.11.3)
Timeout value for database connection, in seconds. Use '0' to specify no timeout. (Since 0.11)
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.
