    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.
    57
    6 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.
     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.

     10== Global Configuration
    911
    10 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.
     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:
     13{{{#!ini
     14[inherit]
     15file = /path/to/global/trac.ini
     16}}}
     17Multiple files can be specified using a comma-separated list. Non-absolute paths are relative to the Environment `conf` directory.
    1118
    12 Global options will be merged with the environment-specific options, where local options override global options. The options file is specified as follows:
    13 {{{
    14 [inherit]
    15 file = /usr/share/trac/conf/trac.ini
    16 }}}
     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.
    1720
    18 Note that you can also specify a global option file when creating a new project,  by adding the option `--inherit=/path/to/global/options` to [TracAdmin trac-admin]'s `initenv` command.  If 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.
     21There are three more options in the [#inherit-section "[inherit]"] section, [#inherit-templates_dir-option templates_dir] for sharing global templates, [#inherit-htdocs_dir-option htdocs_dir] for sharing global htdocs 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.
    1922
     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.

     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.

     33== Configure Error Reporting
    2934
    30 == [components] == #components-section
    31 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.
     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.
    3238
    33 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.
     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:
    3440
    35 Consider the following configuration snippet:
    36 {{{
    37 [components]
    38 trac.ticket.report.ReportModule = disabled
    39 webadmin.* = enabled
    40 }}}
     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`.
    4146
    42 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.
     47If [[#project-admin-option|"[project] admin"]] is not empty, the administrator's email address will be rendered on the error page.
    4348
    44 See the ''Plugins'' page on ''About Trac'' to get the list of active components (requires `CONFIG_VIEW` [wiki:TracPermissions permissions].)

    48 == [ticket-custom] == #ticket-custom-section
    49 
    50 In this section, you can define additional fields for tickets. See TracTicketsCustomFields for more details.
    51 
    52 == [ticket-workflow] == #ticket-workflow-section
    53 ''(since 0.11)''
    54 
    55 The workflow for tickets is controlled by plugins.
    56 By default, there's only a `ConfigurableTicketWorkflow` component in charge.
    57 That component allows the workflow to be configured via this section in the trac.ini file.
    58 See TracWorkflow for more details.
    59 
    60 == [milestone-groups] == #milestone-groups-section
    61 ''(since 0.11)''
    62 
    63 As the workflow for tickets is now configurable, there can be many ticket states,
    64 and simply displaying closed tickets vs. all the others is maybe not appropriate
    65 in all cases. This section enables one to easily create ''groups'' of states
    66 that will be shown in different colors in the milestone progress bar.
    67 
    68 Example configuration (the default only has closed and active):
    69 {{{
    70 closed = closed
    71 # sequence number in the progress bar
    72 closed.order = 0
    73 # optional extra param for the query (two additional columns: created and modified and sort on created)
    74 group=resolution,order=time,col=id,col=summary,col=owner,col=type,col=priority,col=component,col=severity,col=time,col=changetime
    75 # indicates groups that count for overall completion
    76 closed.overall_completion = truepercentage
    77 
    78 new = new
    79 new.order = 1
    80 new.css_class = new
    81 new.label = new
    82 
    83 # one catch-all group is allowed
    84 active = *
    85 active.order = 2
    86 # CSS class for this interval
    87 active.css_class = open
    88 # Displayed label for this group
    89 active.label = in progress
    90 }}}
    91 
    92 The definition consists in a comma-separated list of accepted status.
    93 Also, '*' means any status and could be used to associate all remaining
    94 states to one catch-all group.
    95 
    96 The CSS class can be one of: new (yellow), open (no color) or
    97 closed (green). New styles can easily be added using the following
    98 selector:  `table.progress td.<class>`
    99 
    100 == [svn:externals] == #svn:externals-section
    101 ''(since 0.11)''
    102 
    103 The TracBrowser for Subversion can interpret the `svn:externals` property of folders out of the box.
    104 However, if those externals are ''not'' using the `http:` or `https:` protocol, or if a link to a different repository browser such as another Trac or [http://www.viewvc.org/ ViewVC] is desired, then Trac needs to be able to map an external prefix to this other URL.
    105 
    106 This mapping is done in the `[svn:externals]` section of the TracIni
    107 
    108 Example:
    109 {{{
    110 [svn:externals]
    111 1 = svn://server/repos1 http://trac/proj1/browser/$path?rev=$rev
    112 2 = svn://server/repos2 http://trac/proj2/browser/$path?rev=$rev
    113 3 = http://theirserver.org/svn/eng-soft       http://ourserver/viewvc/svn/$path/?pathrev=25914
    114 4 = svn://anotherserver.com/tools_repository  http://ourserver/tracs/tools/browser/$path?rev=$rev
    115 }}}
    116 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 [http://svnbook.red-bean.com/en/1.4/svn.advanced.externals.html SVN Book on externals] for more details).
    117 
    118 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.
    119 
    120 Finally, the relative URLs introduced in [http://subversion.tigris.org/svn_1.5_releasenotes.html#externals Subversion 1.5] are not yet supported.
     49If the user possesses TRAC_ADMIN, the //Create// button will direct the user to report the issue on trac.edgewall.org. 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.
