     1= The Trac Configuration File
    4 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.
     6Trac is configured through 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.
    6 == Global Configuration ==
     8Trac monitors the timestamp of the file to trigger an environment reload 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 [#GlobalConfiguration global configuration] file when none was previously present.
    8 In versions prior to 0.11, the global configuration was by default located in `$prefix/share/trac/conf/trac.ini` or sometimes /etc/trac/trac.ini depending on the distribution. If you're upgrading, you may want to specify that file to inherit from.
    9 Literally, when you're upgrading to 0.11, you have to add an `inherit`-section to your project's `trac.ini` file. Additionally you have to move your customized templates and common images from `$prefix/share/trac/...` to the new location.
     10== Global Configuration
    11 Global options will be merged with the environment-specific options, where local options override global options. The options file is specified as follows:
    12 {{{
     12Configuration 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:
    14 file = /usr/share/trac/conf/trac.ini
     15file = /path/to/global/trac.ini
     17Multiple files can be specified using a comma-separated list. Non-absolute paths are relative to the Environment `conf` directory.
    17 Note that you can also specify a global option file when creating a new project,  by adding the option
    18 `--inherit=/path/to/global/options` to [TracAdmin trac-admin]'s `initenv` command.
    19 If you would not do this but nevertheless intend to use a global option file with your new environment,
    20 you would have to go through the newly generated conf/trac.ini file and delete the entries that would
    21 otherwise override those set in the global file.
     19Note 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 [TracAdmin#initenv trac-admin]'s `initenv` command. If you specify `--inherit` 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 in the global file.
     21There are two more options in the [[#inherit-section| [inherit] ]] section, [#inherit-templates_dir-option templates_dir] for sharing global templates and [TracIni#inherit-plugins_dir-option plugins_dir], for sharing plugins. Those options can be specified in the shared configuration file, and in fact, configuration files can even be chained if you specify another `[inherit] file` there.
    24 == Reference ==
     23Note 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 to write a custom plugin doing an appropriate `ITemplateStreamFilter` transformation.
    26 This is a brief reference of available configuration options.
     25== Reference for settings
    28 [[TracIni()]]
     27This is a reference of available configuration options, and their default settings.
     29Documentation improvements should be discussed on the [trac:MailingList#Trac-dev trac-dev mailing list] or described in a [trac:NewTicket ticket]. Even better, [trac:TracDev/SubmittingPatches submit a patch] against the docstrings in the code.
    31 == [components] == #components-section
    32 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.
    34 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.
     33== Configure Error Reporting
    36 Consider the following configuration snippet:
    37 {{{
    38 [components]
    39 = disabled
    40 webadmin.* = enabled
    41 }}}
     35The error reporting page has a //Create// button for reporting
     36issues. The site to which issues are reported depends on the
     37configuration of the Trac site and the user’s permissions.
    43 The first option tells Trac to disable the [wiki:TracReports 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.
     39If the user doesn’t possess TRAC_ADMIN, the site to which a user is directed to create a ticket is determined by the [[#project-admin_trac_url-option|"[trac] admin_trac_url"]] setting:
    45 See the ''Plugins'' page on ''About Trac'' to get the list of active components (requires `CONFIG_VIEW` [wiki:TracPermissions permissions].)
     41* If empty, there will be no //Create// button.
     42* If set to the default value (`.`), the ticket will be
     43  created on the site which the error occurred.
     44* Otherwise the ticket will be created at the site pointed
     45  to by `admin_trac_url`.
    47 See also: TracPlugins
     47If [[#project-admin-option|"[project] admin"]] is not empty, the administrator's email address will be rendered on the error page.
    49 == [ticket-custom] == #ticket-custom-section
    51 In this section, you can define additional fields for tickets. See TracTicketsCustomFields for more details.
    53 == [ticket-workflow] == #ticket-workflow-section
    54 ''(since 0.11)''
    56 The workflow for tickets is controlled by plugins.
    57 By default, there's only a `ConfigurableTicketWorkflow` component in charge.
    58 That component allows the workflow to be configured via this section in the trac.ini file.
    59 See TracWorkflow for more details.
    61 == [milestone-groups] == #milestone-groups-section
    62 ''(since 0.11)''
    64 As the workflow for tickets is now configurable, there can be many ticket states,
    65 and simply displaying closed tickets vs. all the others is maybe not appropriate
    66 in all cases. This section enables one to easily create ''groups'' of states
    67 that will be shown in different colors in the milestone progress bar.
    69 Example configuration (the default only has closed and active):
    70 {{{
    71 closed = closed
    72 closed.order = 0                     # sequence number in the progress bar
    73 closed.query_args = group=resolution # optional extra param for the query
    74 closed.overall_completion = true     # indicates groups that count for overall completion percentage
    76 new = new
    77 new.order = 1
    78 new.css_class = new
    79 new.label = new
    81 active = *                           # one catch-all group is allowed
    82 active.order = 1
    83 active.css_class = open              # CSS class for this interval
    84 active.label = in progress           # Displayed label for this group
    85 }}}
    87 The definition consists in a comma-separated list of accepted status.
    88 Also, '*' means any status and could be used to associate all remaining
    89 states to one catch-all group.
    91 The CSS class can be one of: new (yellow), open (no color) or
    92 closed (green). New styles can easily be added using the following
    93 selector:  `table.progress td.<class>`
    95 == [svn:externals] == #svn:externals-section
    96 ''(since 0.11)''
    98 The TracBrowser for Subversion can interpret the `svn:externals` property of folders out of the box.
    99 However, if those externals are ''not'' using the `http:` protocol, or if a link to a different repository browser (such another Trac or [ ViewVC]) is desired, then Trac needs to be able to map an external prefix to this other URL.
    101 This mapping is done in the `[svn:externals]` section of the TracIni
    103 Example:
    104 {{{
    105 [svn:externals]
    106 1 = svn://server/repos1 http://trac/proj1/browser/$path?rev=$rev
    107 2 = svn://server/repos2 http://trac/proj2/browser/$path?rev=$rev
    108 3 =       http://ourserver/viewvc/svn/$path/?pathrev=25914
    109 4 = svn://  http://ourserver/trac/support/browser/$path?rev=$rev
    110 }}}
    111 With the above, the `svn://` external will be mapped to `http://ourserver/trac/support/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).
    113 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.
     49If the user possesses TRAC_ADMIN, the //Create// button will direct the user to report the issue on If the error was generated in a plugin, the error will be reported to the project URL provided that the plugin author has included the project URL in the plugin installation data. The user possessing TRAC_ADMIN also sees a traceback and system information on the error page.
