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_sizeMaximum allowed file size (in bytes) for ticket and wiki attachments.
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 (which is the default).

[batchmod]

fields_as_listfield names modified as a value list(separated by ',')
list_connector_stringConnector string for 'list' fields. Defaults to a space.
list_separator_regexseparator regex used for 'list' fields

[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. (since 0.11)
downloadable_pathsList of repository paths that can be downloaded. Leave the 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) (since 0.10)
hide_propertiesComma-separated list of version control properties to hide from the repository browser. (since 0.9)
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. (since 0.11)
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. (since 0.11)
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. (since 0.11)
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_propertiesComma-separated list of version control properties to render as oneliner wiki content in the repository browser. (since 0.11)
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 (which is the default).
wiki_propertiesComma-separated list of version control properties to render as wiki content in the repository browser. (since 0.11)

[cgit]

cgit_redirectRedirect to cgit project page when true, embed in trac interface when false
cgit_urlURL to cgit project page. Example: /cgit/projectName

[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 (since 0.10).
max_diff_filesMaximum number of modified files for which the changeset view will attempt to show the diffs inlined (since 0.10).
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.

[header_logo]

altAlternative text for the header logo.
heightHeight of the header logo image in pixels.
linkURL to link to, from the header logo.
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.
widthWidth of the header logo image in pixels.

[inherit]

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. (since 0.11)

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)
log_levelLevel of verbosity in log. Should be one of (CRITICAL, ERROR, WARN, INFO, DEBUG).

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.

use_public_ccRecipients can see email addresses of other CC'ed recipients. If this option is disabled (the default), recipients are put on BCC. (since 0.10)
use_short_addrPermit email address without a host/domain (i.e. username only). The SMTP server should accept those addresses, and either append a FQDN or use local delivery. (since 0.10)
use_tlsUse SSL/TLS to send notifications over SMTP. (since 0.10)

[openid]

absolute_trust_rootWhether we should use absolute trust root or by project.
black_listComma separated list of denied OpenId? addresses.
check_listJSON service for openid check.
check_list_keyKey for openid Service.

email_white_listComma separated list of allowed users, using the resolved SREG/AX email address. Use in combination with trusted identity patterns in white_list.
groups_to_requestWhich 'team names' to request via the OpenIDTeams extension. To use this option you must have python-openid-teams installed.
lowercase_authnameWhether authnames should always be lower-cased. Setting this to false generally makes more sense, however this is backwards-incompatible if you already have user sessions which you would like to preserve.
pape_methodDefault PAPE method to request from OpenID provider.
providersExplicit set of provider names to display. E.g: google, yahoo, …
signupSignup link
sreg_requiredWhether SREG data should be required or optional.
strip_protocolInstead of using username beginning with http:// or https:// you can strip the beginning.
strip_trailing_slashIn case your OpenID is some sub-domain address OpenId? library adds trailing slash. This option strips it.
take_default_loginSet to true if /login should be handled by openid.
timeoutSpecify if expiration time should act as timeout. If set, cookie lifetime will be extended to auth_cookie_lifetime on each authenticated access.
trust_authnameWARNING: Only enable this if you know what this mean! This could make identity theft very easy if you do not control the OpenID provider! Enabling this option makes the retrieved authname from the OpenID provider authorative, i.e. it trusts the authname to be the unique username of the user. Enabling this disables the collission checking, so two different OpenID urls may suddenly get the same username if they have the same authname
use_nickname_as_authnameWhether the nickname as retrieved by SReg is used as username
whatisWhat is OpenId? link.
white_listComma separated list of allowed OpenId? addresses.

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

[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)

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. (since 0.9)
workflowOrdered list of workflow controllers to use for ticket actions (since 0.11).

[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. (Since 0.11)

authz_module_nameThe module prefix used in the authz_file for the default repository. If left empty, the global section is used.
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. The default is 2.0 seconds. (since 0.12)
auto_reloadAutomatically reload template files after modification.
backup_dirDatabase backup location
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.

default_languageThe preferred language to use if no user preference has been set. (since 0.12.1)
default_timezoneThe default timezone to use
genshi_cache_sizeThe maximum number of templates that the template loader will cache in memory. The default value is 128. You may want to choose a higher value if your site uses a larger number of templates, and you have enough memory to spare, or you can reduce it if you are short on memory.
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.
mainnavOrder of the items to display in the mainnav navigation bar, listed by IDs. See also TracNavigation.
metanavOrder of the items to display in the metanav navigation bar, listed by IDs. See also TracNavigation.
mysqldump_pathLocation of mysqldump for MySQL database backups
never_obfuscate_mailtoNever obfuscate mailto: links explicitly written in the wiki, even if show_email_addresses is false or the user has not the EMAIL_VIEW permission (since 0.11.6).
permission_policiesList of components implementing IPermissionPolicy, in the order in which they will be applied. These components manage fine-grained access control to Trac resources. Defaults to the DefaultPermissionPolicy? (pre-0.11 behavior) and LegacyAttachmentPolicy? (map ATTACHMENT_* permissions to realm specific ones)
permission_storeName of the component implementing IPermissionStore, which is used for managing user and group permissions.
pg_dump_pathLocation of pg_dump for Postgres database backups
repository_dirPath to the default repository. This can also be a relative path (since 0.11). This option is deprecated, and repositories should be defined in the repositories section, or using the "Repositories" admin panel. (since 0.12)
repository_sync_per_requestList 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)
repository_typeDefault 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)
request_filtersOrdered list of filters to apply to all requests (since 0.10).
resizable_textareasMake <textarea> fields resizable. Requires JavaScript. (since 0.12)
secure_cookiesRestrict 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_addressesShow email addresses instead of usernames. If false, we obfuscate email addresses. (since 0.11)
show_ip_addressesShow IP addresses for resource edits (e.g. wiki). (since 0.11.3)
timeoutTimeout value for database connection, in seconds. Use '0' to specify no timeout. (Since 0.11)
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. (since 0.10.5)

[tracbzr]

include_sideline_changesInclude sideline changes in the list of changes. This option controls whether sideline changes (i.e. changes with dotted revision numbers only) are included in the list of changes as reported by the timeline view. Note that there might be other plugins using that information as well, so there might be other components beside the timeline view that get affected by this setting. Defaults to True.
primary_branchesOrdered list of primary branches. These will be listed first in the Branches macro. When viewing the timeline, each changeset will be associated with the first primary branch that contains it. The value is a comma separated list of globs, as used by the fnmatch module. An empty list element can be used to denote the branch at the root of the repository. Defaults to 'trunk'.

[versioncontrol]

allowed_repository_dir_prefixesComma-separated list of allowed prefixes for repository directories when adding and editing repositories in the repository admin panel. If the list is empty, all repository directories are allowed. (since 0.12.1)

[watchlist]

notificationsEnables notification features

[wiki]

max_sizeMaximum allowed wiki page size in bytes. (since 0.11.2)
render_unsafe_contentEnable/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).
safe_schemesList of URI schemes considered "safe", that will be rendered as external links even if [wiki] render_unsafe_content is false. (since 0.11.8)
split_page_namesEnable/disable splitting the WikiPageNames with space characters (since 0.10).

[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.
