wiki:TracIni

The Trac Configuration File

[Note To Editors] Please discuss documentation changes in the #Discussion section. Even better, send us documentation patches? against the code (i.e. where the configuration entries are documented), either on Trac-dev or on new tickets.

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.

[attachment]

max_size

Maximum allowed file size (in bytes) for attachments.

262144
max_zip_size

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)

2097152
render_unsafe_content

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).

false

[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.

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
link

URL to link to, from the header logo.

(no default)
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

[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.

(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.

(since 0.11)

(no default)
templates_dir

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.

(since 0.11)

(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.

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.

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 (see http://docs.python.org/library/logging.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)

(no default)
log_level

Level of verbosity in log.

Should be one of (CRITICAL, ERROR, WARN, INFO, DEBUG).

DEBUG
log_type

Logging facility to use.

Should be one of (none, file, stderr, syslog, winlog).

none

[milestone]

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.

request_filters

Ordered list of filters to apply to all requests (since 0.10).

(no default)
resizable_textareas

Make <textarea> fields resizable. Requires JavaScript. (since 0.12)

true
secure_cookies

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)

disabled
show_email_addresses

Show email addresses instead of usernames. If false, email addresses are obfuscated for users that don't have EMAIL_VIEW permission. (since 0.11)

false
show_ip_addresses

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)

false
timeout

Timeout value for database connection, in seconds. Use '0' to specify no timeout. (Since 0.11)

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. (since 0.10.5)

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)

false
use_xsendfile

When true, send a X-Sendfile header and no content when sending files from the filesystem, so that the web server handles the content. This requires a web server that knows how to handle such a header, like Apache with mod_xsendfile or lighttpd. (since 1.0)

false
wiki_toolbars

Add a simple toolbar on top of Wiki <textarea>s. (since 1.0.2)

true
xsendfile_header

The header to use if use_xsendfile is enabled. If Nginx is used, set X-Accel-Redirect. (since 1.0.6)

render_unsafe_content

Enable/disable the use of unsafe HTML tags such as <script> or <embed> with the HTML WikiProcessor (since 0.10.4).

For public sites where anonymous users can edit the wiki it is recommended to leave this option disabled (which is the default).

false
safe_origins

List of URIs considered "safe cross-origin", that will be rendered as img element without crossorigin="anonymous" attribute or used in url() of inline style attribute even if [wiki] render_unsafe_content is false (since 1.0.15).

To make any origins safe, specify "*" in the list.

data:
