    6 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.
    77
    8 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.
     8Trac monitors the timestamp of the file to trigger a complete environment reload and flush its caches 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.

    12 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.
    13 
    14 Global options will be merged with the environment-specific options, where local options override global options. The options file is specified as follows:
    15 {{{
     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
    1614[inherit]
    1715file = /path/to/global/trac.ini
    … …  
    1917Multiple files can be specified using a comma-separated list.
    2018
    21 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 [TracAdmin#initenv 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.

    2220
    2321There are two more entries in the [[#inherit-section| [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.
    2422
    25 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).

     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 == Reference for special sections
    34 [[PageOutline(3,,inline)]]
    35 
    36 === [components] === #components-section
    37 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.
    38 
    39 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.
    40 
    41 Consider the following configuration snippet:
    42 {{{
    43 [components]
    44 trac.ticket.report.ReportModule = disabled
    45 webadmin.* = enabled
    46 }}}
    47 
    48 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.
    49 
    50 See the ''Plugins'' page on ''About Trac'' to get the list of active components (requires `CONFIG_VIEW` [wiki:TracPermissions permissions].)
    51 
    52 See also: TracPlugins
    53 
    54 === [extra-permissions] === #extra-permissions-section
    55 ''(since 0.12)''
    56 
    57 Custom additional permissions can be defined in this section when [wiki:ExtraPermissionsProvider] is enabled.
    58 
    59 === [milestone-groups] === #milestone-groups-section
    60 ''(since 0.11)''
    61 
    62 As the workflow for tickets is now configurable, there can be many ticket states,
    63 and simply displaying closed tickets vs. all the others is maybe not appropriate
    64 in all cases. This section enables one to easily create ''groups'' of states
    65 that will be shown in different colors in the milestone progress bar.
    66 
    67 Example configuration (the default only has closed and active):
    68 {{{
    69 closed = closed
    70 # sequence number in the progress bar
    71 closed.order = 0
    72 # optional extra param for the query (two additional columns: created and modified and sort on created)
    73 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
    74 # indicates groups that count for overall completion percentage
    75 closed.overall_completion = true
    76 
    77 new = new
    78 new.order = 1
    79 new.css_class = new
    80 new.label = new
    81 
    82 # one catch-all group is allowed
    83 active = *
    84 active.order = 2
    85 # CSS class for this interval
    86 active.css_class = open
    87 # Displayed label for this group
    88 active.label = in progress
    89 }}}
    90 
    91 The definition consists in a comma-separated list of accepted status.
    92 Also, '*' means any status and could be used to associate all remaining
    93 states to one catch-all group.
    94 
    95 The CSS class can be one of: new (yellow), open (no color) or
    96 closed (green). New styles can easily be added using the following
    97 selector:  `table.progress td.<class>`
    98 
    99 === [repositories] === #repositories-section
    100 
    101 (''since 0.12'' multirepos)
    102 
    103 One of the alternatives for registering new repositories is to populate the `[repositories]` section of the trac.ini.
    104 
    105 This is especially suited for setting up convenience aliases, short-lived repositories, or during the initial phases of an installation.
    106 
    107 See [TracRepositoryAdmin#Intrac.ini TracRepositoryAdmin] for details about the format adopted for this section and the rest of that page for the other alternatives.
    108 
    109 === [svn:externals] === #svn:externals-section
    110 ''(since 0.11)''
    111 
    112 The TracBrowser for Subversion can interpret the `svn:externals` property of folders.
    113 By default, it only turns the URLs into links as Trac can't browse remote repositories.
    114 
    115 However, if you have another Trac instance (or an other repository browser like [http://www.viewvc.org/ ViewVC]) configured to browse the target repository, then you can instruct Trac which other repository browser to use for which external URL.
    116 
    117 This mapping is done in the `[svn:externals]` section of the TracIni
    118 
    119 Example:
    120 {{{
    121 [svn:externals]
    122 1 = svn://server/repos1                       http://trac/proj1/browser/$path?rev=$rev
    123 2 = svn://server/repos2                       http://trac/proj2/browser/$path?rev=$rev
    124 3 = http://theirserver.org/svn/eng-soft       http://ourserver/viewvc/svn/$path/?pathrev=25914
    125 4 = svn://anotherserver.com/tools_repository  http://ourserver/tracs/tools/browser/$path?rev=$rev
    126 }}}
    127 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).
    128 
    129 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.
    130 
    131 Finally, the relative URLs introduced in [http://subversion.tigris.org/svn_1.5_releasenotes.html#externals Subversion 1.5] are not yet supported.
    132 
    133 === [ticket-custom] === #ticket-custom-section
    134 
    135 In this section, you can define additional fields for tickets. See TracTicketsCustomFields for more details.
    136 
    137 === [ticket-workflow] === #ticket-workflow-section
    138 ''(since 0.11)''
    139 
    140 The workflow for tickets is controlled by plugins.
    141 By default, there's only a `ConfigurableTicketWorkflow` component in charge.
    142 That component allows the workflow to be configured via this section in the trac.ini file.
    143 See TracWorkflow for more details.
