The Trac Configuration File
Table of Contents
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 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.
Reference for settings
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 (which is the default). | false |
[authz_policy]
| authz_file | Location of authz policy configuration file. | (no default) |
[browser]
| color_scale | Enable 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) | enabled |
| downloadable_paths | List 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. (since 0.10) | /trunk, /branches/*, /tags/* |
| hide_properties | Comma-separated list of version control properties to hide from the repository browser. (since 0.9) | 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. (since 0.11) | (no default) |
| intermediate_point | If 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) | (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. (since 0.11) | (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. (since 0.11) | (136, 136, 255) |
| oneliner_properties | Comma-separated list of version control properties to render as oneliner wiki content in the repository browser. (since 0.11) | trac:summary |
| render_unsafe_content | Whether 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). | false |
| wiki_properties | Comma-separated list of version control properties to render as wiki content in the repository browser. (since 0.11) | 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 (since 0.10). | 10000000 |
| max_diff_files | Maximum number of modified files for which the changeset view will attempt to show the diffs inlined (since 0.10). | 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. | true |
[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. 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. (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. Non-absolute paths are relative to the Environment conf directory. (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:
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.

[repositories]
One of the alternatives for registering new repositories is to populate the [repositories] section of the trac.ini.

[search]
| default_disabled_filters | Specifies 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_length | Minimum length of query string allowed when performing a search. | 3 |
[sqlite]
| extensions | Paths to sqlite extensions, relative to Trac environment's directory or absolute. (since 0.12) | (no default) |

| eol_style | End-of-Line character sequences when svn:eol-style property is native. If native (the default), 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 |
| tags | Comma 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-v1.1 | tags/* |
[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.

| auth_cookie_lifetime | Lifetime 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 default value of 0 makes the cookie expire at the end of the browsing session. (since 0.12) | 0 |
| auth_cookie_path | Path 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) |

| default_dateinfo_format | The date information format. Valid options are 'relative' for displaying relative format and 'absolute' for displaying absolute format. (since 1.0) | relative |
| default_handler | Name of the component that handles requests to the base URL. Options include TimelineModule, RoadmapModule, BrowserModule, QueryModule, ReportModule, TicketModule and WikiModule. The default is WikiModule. (since 0.9) | WikiModule |
| default_language | The preferred language to use if no user preference has been set. (since 0.12.1) | (no default) |
| default_timezone | The default timezone to use | (no default) |
| genshi_cache_size | The 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. | 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 (since 0.9). | false |
| jquery_location | Location 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_location | Location of the jQuery UI JavaScript library (version 1.8.21). An empty value loads jQuery UI from the copy bundled with Trac. Alternatively, jQuery UI could be loaded from a CDN, for example: https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.21/jquery-ui.min.js or http://ajax.aspnetcdn.com/ajax/jquery.ui/1.8.21/jquery-ui.min.js. (since 1.0) | (no default) |
| jquery_ui_theme_location | Location 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. Alternatively, a jQuery UI theme could be loaded from a CDN, for example: https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.21/themes/start/jquery-ui.css or http://ajax.aspnetcdn.com/ajax/jquery.ui/1.8.21/themes/start/jquery-ui.css. (since 1.0) | (no default) |
| mainnav | Order of the items to display in the mainnav navigation bar, listed by IDs. See also TracNavigation. | wiki, timeline, roadmap, browser, tickets, newticket, search |
| metanav | Order of the items to display in the metanav navigation bar, listed by IDs. See also TracNavigation. | login, logout, prefs, help, about |
| mysqldump_path | Location of mysqldump for MySQL database backups | mysqldump |
| never_obfuscate_mailto | Never obfuscate mailto: links explicitly written in the wiki, even if show_email_addresses is false or the user doesn't have EMAIL_VIEW permission (since 0.11.6). | false |
| permission_policies | List 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) | DefaultPermissionPolicy, LegacyAttachmentPolicy |
| permission_store | Name of the component implementing IPermissionStore, which is used for managing user and group permissions. | DefaultPermissionStore |
| pg_dump_path | Location of pg_dump for Postgres database backups | pg_dump |
| repository_dir | Path 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) | (no default) |
| repository_sync_per_request | List 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) | (default) |
| repository_type | Default repository connector type. (since 0.10) This is also used as the default repository type for repositories defined in the repositories section or using the "Repositories" admin panel. (since 0.12) | svn |
| 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) | X-Sendfile |
[versioncontrol]
| allowed_repository_dir_prefixes | Comma-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) | (no default) |
[wiki]
| ignore_missing_pages | Enable/disable highlighting CamelCase links to missing pages (since 0.9). | false |
| max_size | Maximum allowed wiki page size in characters. (since 0.11.2) | 262144 |
| 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: |
| safe_schemes | List of URI schemes considered "safe", that will be rendered as external links even if [wiki] render_unsafe_content is false. (since 0.11.8) | cvs, file, ftp, git, irc, http, https, news, sftp, smb, ssh, svn, svn+ssh |
| split_page_names | Enable/disable splitting the WikiPageNames with space characters (since 0.10). | false |
Reference for special sections
[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.
See the Plugins page on About Trac to get the list of active components (requires CONFIG_VIEW permissions.)

[milestone-groups]
(since 0.11)
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.
Example configuration (the default only has closed and active):
closed = closed # sequence number in the progress bar closed.order = 0 # optional extra param for the query (two additional columns: created and modified and sort 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 # indicates groups that count for overall completion closed.overall_completion = truepercentage new = new new.order = 1 new.css_class = new new.label = new # one catch-all group is allowed active = * active.order = 2 # CSS class for this interval active.css_class = open # 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). New styles can easily be added using the following selector: table.progress td.<class>
[repositories]
(since 0.12 multirepos)
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.
[svn:externals]
(since 0.11)
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-custom]
In this section, you can define additional fields for tickets. See TracTicketsCustomFields for more details.
[ticket-workflow]
(since 0.11)
The workflow for tickets is controlled by plugins. By default, there's only a ConfigurableTicketWorkflow component in charge. That component allows the workflow to be configured via this section in the trac.ini file. See TracWorkflow for more details.
