The Trac Configuration File

Trac configuration is done by editing the trac.ini config file, located in <projectenv>/conf/trac.ini.

Global Configuration

Since version 0.9, Trac can also read the configuration from a global trac.ini file. These global options will then be merged with the environment-specific options, where local options override global options.

The global configuration is by default localted in $prefix/share/trac/conf/trac.ini. It can be moved to a different location (for example, /etc/trac.ini), but that requires changing the file trac/siteconfig.py which gets created when Trac is installed.

Reference

This is a brief reference of available configuration options.

[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.

disabled

[authz_policy]

authz_file

Location of authz policy configuration file. Non-absolute paths are relative to the Environment conf directory.

(no default)

[browser]

oneliner_properties

Comma-separated list of version control properties to render as oneliner wiki content in the repository browser.

trac:summary
wiki_properties

Comma-separated list of version control properties to render as wiki content in the repository browser.

trac:description

[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.

10000000
max_diff_files

Maximum number of modified files for which the changeset view will attempt to show the diffs inlined.

0
wiki_format_messages

Whether wiki formatting should be applied to changeset messages.

If this option is disabled, changeset messages will be rendered as pre-formatted text.

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

[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
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

[http-headers]

Headers to be added to the HTTP request. (since 1.2.3)

The header name must conform to RFC7230 and the following reserved names are not allowed: content-type, content-length, location, etag, pragma, cache-control, expires.

[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.

Non-absolute paths are relative to the Environment conf directory. (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.

Non-absolute paths are relative to the Environment conf directory.

(no default)

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.

Non-absolute paths are relative to the Environment conf directory.

[iniadmin]

excludes

Excludes this options. Comma separated list as section:name with wildcard characters (*, ?).

iniadmin:*,inherit:*
passwords

Show input-type as password instead of text. Comma separated list as section:name with wildcard characters.

trac:database,notification:smtp_password

[intertrac]

This section configures InterTrac prefixes. Option names in this section that contain a . are of the format <name>.<attribute>. Option names that don't contain a . define an alias.

The .url attribute is mandatory and is used for locating the other Trac. This can be a relative path when the other Trac environment is located on the same server.

The .title attribute is used for generating a tooltip when the cursor is hovered over an InterTrac link.

Example configuration:

[intertrac]
# -- Example of setting up an alias:
t = trac

# -- Link to an external Trac:
genshi.title = Edgewall's Trac for Genshi
genshi.url = https://genshi.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 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

(no default)
log_level

Level of verbosity in log.

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

INFO
log_type

Logging facility to use.

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

file

Configures the main navigation bar, which by default contains Wiki, Timeline, Roadmap, Browse Source, View Tickets, New Ticket, Search and Admin.

The label, href, and order attributes can be specified. Entries can be disabled by setting the value of the navigation item to disabled.

The following example renames the link to WikiStart to Home, links the View Tickets entry to a specific report and disables the Search entry.

[mainnav]
wiki.label = Home
tickets.href = /report/24
search = disabled

See TracNavigation for more details.

[metanav]

Configures the meta navigation entries, which by default are Login, Logout, Preferences, Help/Guide and About Trac. The allowed attributes are the same as for [mainnav]. Additionally, a special entry is supported - logout.redirect is the page the user sees after hitting the logout button. For example:

[metanav]
logout.redirect = wiki/Logout

See TracNavigation for more details.

[milestone]

default_group_by

Default field to use for grouping tickets in the grouped progress bar. (since 1.2)

component
default_retarget_to

Default milestone to which tickets are retargeted when closing or deleting a milestone. (since 1.1.2)

(no default)
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.

[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.

restrict_owner

Make the owner field of tickets use a drop-down menu. Be sure to understand the performance implications before activating this option. See Assign-to as Drop-Down List.

Please note that e-mail addresses are not obfuscated in the resulting drop-down menu, so this option should not be used if e-mail addresses must remain protected.

disabled
workflow

Ordered list of workflow controllers to use for ticket actions.

ConfigurableTicketWorkflow

[ticket-custom]

In this section, you can define additional fields for tickets. See TracTicketsCustomFields for more details.

[timeline]

abbreviated_messages

Whether wiki-formatted event messages should be truncated or not.

This only affects the default rendering, and can be overriden by specific event providers, see their own documentation.

Whether consecutive changesets from the same author having exactly the same message should be presented as one event. That event will link to the range of changesets in the log view.

disabled
changeset_long_messages

(deprecated, will be removed in Trac 1.5.1)

128
htdocs_location

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.

(no default)
ignore_auth_case

Whether login names should be converted to lower case.

disabled
jquery_location

Location of the jQuery JavaScript library (version 1.12.4).

An empty value loads jQuery from the copy bundled with Trac.

(since 1.0)

(no default)
jquery_ui_location

Location of the jQuery UI JavaScript library (version 1.12.1).

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.

disabled
show_email_addresses

disabled
show_full_names

Show full names instead of usernames. (since 1.2)

enabled
timeout

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

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.

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)

enabled
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)

disabled
wiki_toolbars

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

disabled

[components]

(since 0.9)

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

Note that prior to Trac r2335 (that applies to 0.9b1 and 0.9b2), you would use a [disabled_components] section instead. See a previous version of this page for the details.
