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.

Note that the [hg], [spam-filter], [translatedpages], [vote], [wikiextras] and [wikiextras-symbols] sections below are added by plugins enabled on this Trac, and therefore won't be part of a default installation.

[account-manager]

refresh_passwdRe-set passwords on successful authentication. This is most useful to move users to a new password store or enforce new store configuration (i.e. changed hash type), but should be disabled/unset otherwise.disabled
register_basic_tokenA string required as input to pass verification.(no default)
register_checkOrdered list of IAccountRegistrationInspector's to use for registration checks.BasicCheck, EmailCheck, BotTrapCheck, RegExpCheck, UsernamePermCheck

[attachment]

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

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).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).

[google_analytics]

admin_loggingDisabling this option will prevent all logged in admins from showing up on your Google Analytics reports.disabled
extensionsEnter any extensions of files you would like to be tracked as a download. For example to track all MP3s and PDFs enter: mp3,pdf Outbound link tracking must be enabled for downloads to be tracked.zip,tar,tar.gz,tar.bzip,egg
google_external_pathThis will be the path shown on Google Analytics regarding external links. Consider the following link: http://trac.edgewall.org/" The above link will be shown as for example: /external/trac.edgewall.org/ This way you will be able to track outgoing links. Outbound link tracking must be enabled for external links to be tracked./external/
outbound_link_trackingDisabling this option will turn off the tracking of outbound links. It's recommended not to disable this option unless you're a privacy advocate (now why would you be using Google Analytics in the first place?) or it's causing some kind of weird issue.enabled
tracking_domain_nameIf you're tracking multiple subdomains with the same Google Analytics profile, like what's talked about in: https://www.google.com/support/googleanalytics/bin/answer.py?answer=55524 enter your main domain here. For more info, please visit the previous link.(no default)
uidGoogle Analytics' UID. The UID is needed for Google Analytics to log your website stats. Your UID can be found by looking in the JavaScript? Google Analytics gives you to put on your page. Look for your UID in between var pageTracker = _gat._getTracker("UA-111111-11"); in the javascript. In this example you would put UA-11111-1 in the UID box.(no default)

[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. (since 0.11)(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. (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_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 (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_levelLevel of verbosity in log. Should be one of (CRITICAL, ERROR, WARN, INFO, DEBUG).DEBUG
log_typeLogging facility to use. Should be one of (none, file, stderr, syslog, winlog).none

[milestone]

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.

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

[secdl]

duplicateSpecify what to do if a file is uploaded with an already existing file name. To deny the upload, set it to 'deny' (default), set it to 'allow' to allow two files with the same name. Note that this applies only to local downloads, remote downloads are not restricted.deny
extensionsComma separated list of allowed file extensions (without leading dot). Leave this empty to not restrict the file types. The default is 'zip,gz,bz2,rar'. See also the 'no_extension' option.zip,gz,bz2,rar
lighty_prefixMust be set to the Lighttpd 'secdownload-uri-prefix' configuration value if mod_secdownload is used. The final download URL will be constructed using this value as the first part after the root path, followed by the protected part of the URL. If regular downloads are enabled, the URL will be the same but without the protected part. Note that if you do not start the value for this option with a '/', an URL relative to the Trac environment root will be created. This is in most cases not what you want!/download/
lighty_secretThe secret key to protect the downloads (Lighttpd 'secdownload.secret' configuration value). The downloads using mod_secdownload are disabled if this is left empty (default).(no default)
max_filesMaximum number of uploaded files. If this limit is reached, no more uploads are allowed. Set this to '0' to allow an unlimited number of uploads (default). Note that this applies to local files only.0
max_sizeMaximum allowed file size for uploaded files in bytes. Note that a file has to be uploaded completely before this can be checked. Set 'max_size' to '0' to not restrict the file size. The default value is '524288' (512 KiB). See also the 'max_total' configuration option. Note that this applies to local files only.524288
max_totalMaximum total size of uploaded files in bytes. If a new file upload would exceed this limit it will be denied. Note that a file has to be uploaded completely before this can be checked (unless the limit is already reached). Set this to '0' to disable this feature (default). This applies to local files only.0
no_extensionIn addition to the allowed file extensions specified by the 'extensions' option, allow files with no extension to be uploaded if this option is set to True. The default value is False.disabled
orderDefault order of the downloads table, specified as comma separated list of field names. See 'show_fields' for a list of allowed field names. You may prepend a '!' to change the sort order of a given field (eg. use '!name' to sort by file name in a descending order). Note that the fields used here have to be included in the 'show_fields' list, too. The default value is '!time', so latest downloads will be shown at the top of the table.!time
regular_downloadsEnable regular downloads not using mod_secdownload. Note that the webserver has to be configured to serve the files in 'upload_dir'. This option will be ignored unless 'lighty_secret' is empty and 'use_xsendfile' is disabled. Regular downloads may be used on other servers than Lighttpd, too, but keep in mind that there are no further restrictions to access these files.disabled
schemesComma separated list of allowed schemes for the remote downloads. A remote download with another scheme can not be created. To not restrict the remote URLs leave this option empty. Note that URLs without a scheme are always denied. The default is 'http,https'.http,https
show_fieldsComma separated list of fields to show on the downloads index page. Valid options are: 'id', 'name', 'url', 'description', 'size', 'time', 'last_request', 'count', 'author', 'ip', 'component', 'version', 'milestone', 'platform', 'architecture', 'type', 'hidden', 'checksum_md5', 'checksum_sha'. Note that some options are not displayed in a separate column but will force a new table row, and some options are not displayed at all (though they are valid). The order does not matter.name,size,description,url,time,checksum_md5,checksum_sha
temp_dirTemporary directory for uploaded files. If this is empty (default) 'upload_dir' will be used. Note that it is highly recommended to use a directory on the same physical partition as 'upload_dir'. The directory must exist and the user running Trac must have write access to this directory.(no default)
titleMain navigation link title, and title of the downloads index page. Defaults to 'Downloads'.Downloads
trac_downloadsIf 'lighty_secret' is not set and 'regular_downloads' is disabled, too, this option can be enabled to allow downloads to be handled by Trac itself. This is disabled by default.disabled
unmanaged_file_external_prefixIf using a 'unmanaged_file_prefix' and 'regular' file serving, this needs to be set to the prefix the files stored under 'unmanaged_file_prefix' are being exposed via the web server.(no default)
unmanaged_file_prefixIf you are going to use unmanaged locally hosted files not uploaded using the admin interface, this must be set to a prefix relative to which these local files can be found. Don't set this to / - that'll cause potential leakage!!!/dev/null/
upload_dirDirectory to store uploaded files. The directory must exist and the user running Trac must have write access to this directory. The user running Lighttpd (or any other webserver if regular downloads are used) must have read permissions. The default value is '/var/lib/trac/files'. Note that you can safely use the same upload directory for multiple environments, the uploaded files are automatically stored in subdirectories for each environment./var/lib/trac/files
urlURL of the downloads page relative to the Trac environment root (one word, no slashes). Defaults to 'download'.download
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.disabled
wiki_prefixComma separated list of prefixes used in the wiki to link to the downloads. The default value is 'download,secdownload'.download,secdownload

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 (since 0.9).false
jquery_locationLocation of the jQuery JavaScript library (version 1.7.2). 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. (since 1.0)(no default)
jquery_ui_locationLocation of the jQuery UI JavaScript library (version 1.8.21). An empty value loads jQuery UI from the copy bundled with Trac.

(since 1.0)(no default)
jquery_ui_theme_locationLocation of the theme to be used with the jQuery UI JavaScript library (version 1.8.21). An empty value loads the custom Trac jQuery UI theme from the copy bundled with Trac.

timeoutTimeout value for database connection, in seconds. Use '0' to specify no timeout. (Since 0.11)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. (since 0.10.5)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)false
