            |  | 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. | 
          
            |  | 7 |  | 
          
            |  | 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. | 
          
            |  | 9 |  | 
          
            |  | 10 | == Global Configuration == | 
          
            |  | 11 |  | 
          
            |  | 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 | {{{ | 
          
            |  | 16 | [inherit] | 
          
            |  | 17 | file = /path/to/global/trac.ini | 
          
            |  | 18 | }}} | 
          
            |  | 19 | Multiple files can be specified using a comma-separated list. | 
          
            |  | 20 |  | 
          
            |  | 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. | 
          
            |  | 22 |  | 
          
            |  | 23 | There 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. | 
          
            |  | 24 |  | 
          
            |  | 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). |

            |  | 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].) |

            |  | 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 |

            |  | 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 |

            |  | 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] |

            |  | 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 |

            |  | 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. |

            |  | 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. |
