    44== Quick start #QuickStart
    55
    6  * Enable the repository connector(s) for the version control system(s) that you will use.
    7  * Add repositories through the //Repositories// admin panel, with `trac-admin` or in the `[repositories]` section of [wiki:TracIni#repositories-section trac.ini].
     6 * Manage repositories in the "Repository" admin panel, with `trac-admin` or in the `[repositories]` section of [wiki:TracIni#repositories-section trac.ini].
    87 * Set up a call to `trac-admin $ENV changeset added $REPO $REV` in the post-commit hook of each repository. Additionally, add a call to `trac-admin $ENV changeset modified $REPO $REV` in the post-revprop-change hook of repositories allowing revision property changes.
    9  * Make sure the user under which your hooks are run has write access to the Trac environment, or use a tool like `sudo` to temporarily elevate privileges.
    10 
    11 == Enabling the components
    12 
    13 Support for version control systems is provided by optional components distributed with Trac, which are disabled by default //(since 1.0)//. Subversion and Git must be explicitly enabled if you wish to use them.
    14 
    15 The version control systems can be enabled by adding the following to the `[components]` section of your [TracIni#components-section trac.ini], or enabling the components in the //Plugins// admin panel.
    16 
    17 {{{#!ini
    18 tracopt.versioncontrol.svn.* = enabled
    19 }}}
    20 
    21 {{{#!ini
    22 tracopt.versioncontrol.git.* = enabled
    23 }}}
     8 * Set the `[trac] repository_sync_per_request` option to an empty value to disable per-request syncing.
     9 * Make sure the user under which your Subversion hooks are run has write access to the Trac environment, or use a tool like `sudo` to temporarily elevate privileges.

    2511== Specifying repositories #Repositories
    26 Trac supports multiple repositories per environment, and the repositories may be for different version control system types. Each repository must be defined in a repository configuration provider, the two supported by default are the [#ReposDatabase database store] and the [#ReposTracIni trac.ini configuration file]. A repository should not be defined in multiple configuration providers.
    27 
    28 It is possible to define aliases of repositories, that act as "pointers" to real repositories. This can be useful when renaming a repository, to avoid breaking links to the old name.
    29 
    30 A number of attributes can be associated with each repository. The attributes define the repository's location, type, name and how it is displayed in the source browser. The following attributes are supported:
     12Starting with 0.12, Trac can handle more than one repository per environment. The pre-0.12 way of specifying the repository with the `repository_dir` and `repository_type` options in the `[trac]` section of [wiki:TracIni trac.ini] is still supported, but two new mechanisms allow including additional repositories into an environment.
     13
     14It is also possible to define aliases of repositories, that act as "pointers" to real repositories. This can be useful when renaming a repository, to avoid breaking all the links to the old name.
     15
     16A number of attributes can be associated with each repository, which define the repository's location, type, name and how it is displayed in the source browser. The following attributes are supported:
    3117
    3218||='''Attribute''' =||='''Description''' =||
     
    3824||The `dir` attribute specifies the location of the repository in the filesystem. It corresponds to the value previously specified in the option `[trac] repository_dir`. The `alias` and `dir` attributes are mutually exclusive. ||
    3925||`hidden` ||When set to `true`, the repository is hidden from the repository index page in the source browser. Browsing the repository is still possible, and links referencing the repository remain valid. ||
    40 ||`sync_per_request`||When set to `true` the repository will be synced on every request. This is not recommended, instead a post-commit hook should be configured to provide [#ExplicitSync explicit synchronization] and `sync_per_request` should be set to `false`.||
    4126||`type` ||The `type` attribute sets the type of version control system used by the repository. Trac supports Subversion and Git out-of-the-box, and plugins add support for many other systems. If `type` is not specified, it defaults to the value of the `[trac] repository_type` option. ||
    4227||`url` ||The `url` attribute specifies the root URL to be used for checking out from the repository. When specified, a "Repository URL" link is added to the context navigation links in the source browser, that can be copied into the tool used for creating the working copy. ||
    4328
    4429A repository `name` and one of `alias` or `dir` attributes are mandatory. All others are optional.
    45 
    46 For some version control systems, it is possible to specify not only the path to the repository in the `dir` attribute, but also a ''scope'' within the repository. Trac will then only show information related to the files and changesets below that scope. The Subversion backend for Trac supports this. For other types, check the corresponding plugin's documentation.

    4831After adding a repository, the cache for that repository must be re-synchronized once with the `trac-admin $ENV repository resync` command.

    11295=== Explicit synchronization #ExplicitSync
    113 This is the preferred method of repository synchronization. It requires setting the `sync_per_request` attribute to `false`, and adding a call to `trac-admin` in the `post-commit` hook of each repository. Additionally, if a repository allows changing revision metadata, a call to `trac-admin` must be added to the `post-revprop-change` hook as well.
     96This is the preferred method of repository synchronization. It requires setting the `[trac]  repository_sync_per_request` option in [wiki:TracIni#trac-section trac.ini] to an empty value, and adding a call to `trac-admin` in the `post-commit` hook of each repository. Additionally, if a repository allows changing revision metadata, a call to `trac-admin` must be added to the `post-revprop-change` hook as well.

    199182=== Per-request synchronization #PerRequestSync
    200 If the post-commit hooks are not available, the environment can be set up for per-request synchronization. In that case, the `sync_per_request` attribute for each repository in the database and in [wiki:TracIni#trac-section trac.ini] must be set to `false`.
     183If the post-commit hooks are not available, the environment can be set up for per-request synchronization. In that case, the `[trac] repository_sync_per_request` option in [wiki:TracIni#trac-section trac.ini] must be set to a comma-separated list of repository names to be synchronized.
    201184
    202185Note that in this case, the changeset listener extension point is not called, and therefore plugins using it will not work correctly.

     200== Migration from a single-repository setup (Subversion) #Migration
     201The following procedure illustrates a typical migration from a Subversion single-repository setup to multiple repositories.
     202
     203 1. Remove the default repository specification from the `[trac] repository_dir` option.
     204 1. Add the main repository as a named repository.
     205 1. Re-synchronize the main repository.
     206 1. Set up post-commit and post-revprop-change hooks on the "main" repository, and set `[trac] repository_sync_per_request` to an empty value.
     207 1. Add an alias to the main repository as the default repository (by leaving out the the `name`, e.g. `.alias = main`). This ensures that all links predating the migration still resolve to the main repository.
     208 1. Repeat steps 2, 3 and 4 to add other "named" repositories as needed.
     209
     210== Migration from a single-repository setup (Mercurial) #MigrationMercurial
     211The following procedure illustrates a typical migration from a Mercurial single-repository setup to multiple repositories. Please note that at the time of writing, no initial resynchronization or any hooks are necessary for Mercurial repositories - see [trac:ticket:9485 #9485] for more information.
     212
     213 1. Upgrade to the latest version of the [trac:TracMercurial] plugin.
     214 1. Remove the default repository specification from the `[trac] repository_dir` option.
     215 1. Add the main repository as a named repository.
     216 1. Add an alias to the main repository as the default repository (by leaving out the the `name`, e.g. `.alias = main`). This ensures that all links predating the migration still resolve to the main repository.
     217 1. Repeat step 3 to add other "named" repositories as needed.
