= The Trac Configuration File =

Trac configuration is done by editing the '''`trac.ini`''' config file, located in `<projectenv>/conf/trac.ini`.

== Global Configuration ==

Since version 0.9, Trac can also read the configuration from a global `trac.ini` file. These global options will then be merged with the environment-specific options, where local options override global options.

The global configuration is by default located in `$prefix/share/trac/conf/trac.ini`. It can be moved to a different location (for example, `/etc/trac.ini`), but that requires changing the file `trac/` which gets created when Trac is installed. 

== Reference ==

This is a brief reference of available configuration options.

'''Note: since [milestone:0.10], the TracIni reference is auto-generated
from the source code, using the TracIniMacro. But in this page, we will keep
the old ''wiki'' content, so that documentation fixes could be easily 
contributed by the community, as before.'''

== [trac] ==
|| `base_url` || Base URL of the Trac deployment.[[BR]]In most configurations, Trac will automatically reconstruct the URL that is used to access it automatically.

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] = disabled
webadmin.* = enabled

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. To get a list of active components for your installation, see the ''Plugins'' page on ''About Trac'' (requires `CONFIG_VIEW` [wiki:TracPermissions permissions].)

== [changeset] ==
(''since 0.10'')

|| `max_diff_bytes` || A limit for the sum of the size of all old ''and'' new files involved in a changeset. [[br]] Note that when requesting a diff precisely on a very big file (e.g. by the use of the ''Last Change'' link), the size limit will ''not'' be taken into account and the diffs will always be computed. ||
