wiki:TracIni

The Trac Configuration File

Trac is configured by editing 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.

Global Configuration

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.

Documentation improvements should be discussed on the trac-dev mailing list or described in a ticket. Even better, submit a patch against the docstrings in the code.

[account-manager]

account_changes_notify_addressesList of email addresses that get notified of user changes, ie, new user, password change and delete user.(no default)

[attachment]

max_sizeMaximum allowed file size (in bytes) for attachments.262144
max_zip_sizeMaximum 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_contentWhether 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

[browser]

color_scaleEnable colorization of the age column. This uses the same color scale as the source code annotation: blue is older, red is newer.enabled
downloadable_pathsList of repository paths that can be downloaded. Leave this option empty if you want to disable all downloads, otherwise set it to a comma-separated list of authorized paths (those paths are glob patterns, i.e. "*" can be used as a wild card). In a multi-repository environment, the path must be qualified with the repository name if the path does not point to the default repository (e.g. /reponame/trunk). Note that a simple prefix matching is performed on the paths, so aliases won't get automatically resolved./trunk,/branches/*,/tags/*
hide_propertiesComma-separated list of version control properties to hide from the repository browser.svk:merge
intermediate_color(r,g,b) color triple to use for the color corresponding to the intermediate color, if two linear interpolations are used for the color scale (see intermediate_point). If not set, the intermediate color between oldest_color and newest_color will be used.(no default)
intermediate_pointIf set to a value between 0 and 1 (exclusive), this will be the point chosen to set the intermediate_color for interpolating the color value.(no default)
newest_color(r,g,b) color triple to use for the color corresponding to the newest color, for the color scale used in blame or the browser age column if color_scale is enabled.(255, 136, 136)
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.(136, 136, 255)
oneliner_propertiesComma-separated list of version control properties to render as oneliner wiki content in the repository browser.trac:summary
render_unsafe_contentWhether 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.disabled
wiki_propertiesComma-separated list of version control properties to render as wiki content in the repository browser.trac:description

[changeset]

max_diff_bytesMaximum 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_filesMaximum number of modified files for which the changeset view will attempt to show the diffs inlined.0
wiki_format_messagesWhether 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).

[header_logo]

altAlternative text for the header logo.(please configure the [header_logo] section in trac.ini)
heightHeight of the header logo image in pixels.-1
linkURL to link to, from the header logo.(no default)
srcURL 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
widthWidth of the header logo image in pixels.-1

[inherit]

htdocs_dirPath 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_dirPath 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.(no default)
templates_dirPath 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.(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.

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_fileIf 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_formatCustom 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_levelLevel of verbosity in log. Should be one of (CRITICAL, ERROR, WARNING, INFO, DEBUG).DEBUG
log_typeLogging facility to use. Should be one of (none, file, stderr, syslog, winlog).none

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_retarget_toDefault milestone to which tickets are retargeted when closing or deleting a milestone. (since 1.1.2)(no default)
stats_providerName 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.

[mimeviewer]

max_preview_sizeMaximum file size for HTML preview.262144
mime_mapList of additional MIME types and keyword mappings. Mappings are comma-separated, and for each MIME type, there's a colon (":") separated list of associated keywords or file extensions.text/x-dylan:dylan,text/x-idl:ice,text/x-ada:ads:adb

pygments_default_styleThe default style to use for Pygments syntax highlighting.trac
pygments_modesList of additional MIME types known by Pygments. For each, a tuple mimetype:mode:quality has to be specified, where mimetype is the MIME type, mode is the corresponding Pygments mode to be used for the conversion and quality is the quality ratio associated to this conversion. That can also be used to override the default quality ratio used by the Pygments render.(no default)

ignore_domainsComma-separated list of domains that should not be considered part of email addresses (for usernames with Kerberos domains).(no default)
mime_encodingSpecifies the MIME encoding scheme for emails. Supported values are: none, the default value which uses 7-bit encoding if the text is plain ASCII or 8-bit otherwise. base64, which works with any kind of content but may cause some issues with touchy anti-spam/anti-virus engine. qp or quoted-printable, which works best for european languages (more compact than base64) if 8-bit encoding cannot be used.none
sendmail_pathPath to the sendmail executable. The sendmail program must accept the -i and -f options. (since 0.12)sendmail
smtp_always_bccComma-separated list of email addresses to always send notifications to. Addresses are not public (Bcc:).(no default)
smtp_always_ccComma-separated list of email addresses to always send notifications to. Addresses can be seen by all recipients (Cc:).(no default)

items_per_page_rssNumber of tickets displayed in the rss feeds for reports.0

[repositories]

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.

(since 0.12)

[revisionlog]

default_log_limitDefault value for the limit argument in the TracRevisionLog.100

stats_providerName of the component implementing ITicketGroupStatsProvider, which is used to collect statistics on groups of tickets for display in the roadmap views.DefaultTicketGroupStatsProvider

[search]

default_disabled_filtersSpecifies which search filters should be disabled by default on the search page. This will also restrict the filters for the quick search function. The filter names defined by default components are: wiki, ticket, milestone and changeset. For plugins, look for their implementation of the ISearchSource interface, in the get_search_filters() method, the first member of returned tuple. Once disabled, search filters can still be manually enabled by the user on the search page. (since 0.12)(no default)
min_query_lengthMinimum length of query string allowed when performing a search.3

[sqlite]

extensionsPaths to sqlite extensions, relative to Trac environment's directory or absolute. (since 0.12)(no default)

[svn]

authz_fileThe path to the Subversion authorization (authz) file. To enable authz permission checking, the AuthzSourcePolicy permission policy must be added to [trac] permission_policies. Non-absolute paths are relative to the Environment conf directory.(no default)
authz_module_nameThe module prefix used in the authz_file for the default repository. If left empty, the global section is used.(no default)
branchesComma separated list of paths categorized as branches. If a path ends with '*', then all the directory entries found below that path will be included. Example: /trunk, /branches/*, /projectAlpha/trunk, /sandbox/*trunk,branches/*
eol_styleEnd-of-Line character sequences when svn:eol-style property is native. If native, substitute with the native EOL marker on the server. Otherwise, if LF, CRLF or CR, substitute with the specified EOL marker. (since 1.0.2)native
tagsComma separated list of paths categorized as tags. If a path ends with '*', then all the directory entries found below that path will be included. Example: /tags/*, /projectAlpha/tags/A-1.0, /projectAlpha/tags/A-v1.1tags/*

[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.

Finally, the relative URLs introduced in Subversion 1.5 are not yet supported.

[ticket]

restrict_ownerMake 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
workflowOrdered 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.

[ticket-workflow]

[timeline]

abbreviated_messagesWhether 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.enabled
changeset_collapse_eventsWhether 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_messagesWhether wiki-formatted changeset messages should be multiline or not. If this option is not specified or is false and wiki_format_messages is set to true, changeset messages will be single line only, losing some formatting (bullet points, etc).disabled

ticket_show_detailsEnable the display of all ticket changes in the timeline, not only open / close operations.disabled

[trac]

auth_cookie_lifetimeLifetime of the authentication cookie, in seconds. This value determines how long the browser will cache authentication information, and therefore, after how much inactivity a user will have to log in again. The value of 0 makes the cookie expire at the end of the browsing session. (since 0.12)0
auth_cookie_pathPath for the authentication cookie. Set this to the common base path of several Trac instances if you want them to share the cookie. (since 0.12)(no default)
auto_preview_timeoutInactivity timeout in seconds after which the automatic wiki preview triggers an update. This option can contain floating-point values. The lower the setting, the more requests will be made to the server. Set this to 0 to disable automatic preview. (since 0.12)2.0
auto_reloadAutomatically reload template files after modification.disabled
backup_dirDatabase backup locationdb
base_urlReference URL for the Trac deployment. This is the base URL that will be used when producing documents that will be used outside of the web browsing context, like for example when inserting URLs pointing to Trac resources in notification e-mails.(no default)
check_auth_ipWhether the IP address of the user should be checked for authentication.disabled
databaseDatabase connection string for this projectsqlite:db/trac.db

htdocs_locationBase 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_caseWhether login names should be converted to lower case.disabled
jquery_locationLocation of the jQuery JavaScript library (version 1.8.3). 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-1.8.3.min.js, http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.8.3.min.js or https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js.

show_email_addressesShow email addresses instead of usernames. If false, email addresses are obfuscated for users that don't have EMAIL_VIEW permission.disabled

timeoutTimeout value for database connection, in seconds. Use '0' to specify no timeout.20
use_base_url_for_redirectOptionally 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_encodingIf 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)disabled
use_xsendfileWhen 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_toolbarsAdd a simple toolbar on top of Wiki <textarea>s. (since 1.0.2)enabled
xsendfile_headerThe header to use if use_xsendfile is enabled. If Nginx is used, set X-Accel-Redirect. (since 1.0.6)X-Sendfile
