    66 * Manage repositories in the "Repository" admin panel, with `trac-admin` or in the `[repositories]` section of [wiki:TracIni#repositories-section trac.ini].
     
    99 * 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.

    11 == Specifying repositories == #Repositories
     11== Specifying repositories #Repositories
    1212Starting 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.

    37 === In `trac.ini` === #ReposTracIni
     37=== In `trac.ini` #ReposTracIni
    3838Repositories and repository attributes can be specified in the `[repositories]` section of [wiki:TracIni#repositories-section trac.ini]. Every attribute consists of a key structured as `{name}.{attribute}` and the corresponding value separated with an equal sign (`=`). The name of the default repository is empty.
    3939

    4242The following example defines two Subversion repositories named `project` and `lib`, and an alias to `project` as the default repository. This is a typical use case where a Trac environment previously had a single repository (the `project` repository), and was converted to multiple repositories. The alias ensures that links predating the change continue to resolve to the `project` repository.

    5958Note that `name.alias = target` makes `name` an alias for the `target` repo, not the other way around.

    61 === In the database === #ReposDatabase
     60=== In the database #ReposDatabase
    6261Repositories can also be specified in the database, using either the "Repositories" admin panel under "Version Control", or the `trac-admin $ENV repository` commands.
    6362
     
    8079Note that the default repository has an empty name, so it will likely need to be quoted when running `trac-admin` from a shell. Alternatively, the name "`(default)`" can be used instead, for example when running `trac-admin` in interactive mode.

    82 
    83 == Repository synchronization == #Synchronization
     81== Repository caching
     82
     83The Subversion and Git repository connectors support caching, which improves the performance browsing the repository, viewing logs and viewing changesets. Cached repositories must be [#Synchronization synchronized]; either explicit or implicit synchronization can be used. When searching changesets, only cached repositories are searched.
     84
     85Subversion repositories are cached unless the type is `direct-svnfs`. Git repositories are cached when `[git]` [wiki:TracIni#git-section cached_repository] is `true`.
     86
     87== Repository synchronization #Synchronization
    8488Prior to 0.12, Trac synchronized its cache with the repository on every HTTP request. This approach is not very efficient and not practical anymore with multiple repositories. For this reason, explicit synchronization through post-commit hooks was added.
    8589
    8690There is also new functionality in the form of a repository listener extension point ''(IRepositoryChangeListener)'' that is triggered by the post-commit hook when a changeset is added or modified, and can be used by plugins to perform actions on commit.
    8791
    88 === Mercurial Repositories ===
     92=== Mercurial Repositories
    8993Please note that at the time of writing, no initial resynchronization or any hooks are necessary for Mercurial repositories - see [trac:#9485] for more information.
    9094
    91 === Explicit synchronization === #ExplicitSync
     95=== Explicit synchronization #ExplicitSync
    9296This 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.
    9397
     
    102106Note that you may have to set the environment variable `PYTHON_EGG_CACHE` to the same value as was used for the web server configuration before calling `trac-admin`, if you changed it from its default location. See [wiki:TracPlugins Trac Plugins] for more information.

    106110The following examples are complete post-commit and post-revprop-change scripts for Subversion. They should be edited for the specific environment, marked executable (where applicable) and placed in the `hooks` directory of each repository. On Unix (`post-commit`):
     
    133137See the [http://svnbook.red-bean.com/en/1.5/svn.reposadmin.create.html#svn.reposadmin.create.hooks section about hooks] in the Subversion book for more information. Other repository types will require different hook setups.
    134138
    135 ==== Git ====
    136 
    137 Git hooks can be used in the same way for explicit syncing of Git repositories.  If your git repository is one that gets committed to directly on the machine that hosts trac, add the following to the `hooks/post-receive` file in your git repo (note: this will do nothing if you only update the repo by pushing to it):

    159166For Mercurial, add the following entries to the `.hgrc` file of each repository accessed by Trac (if [trac:TracMercurial] is installed in a Trac `plugins` directory, download [trac:source:mercurial-plugin/tracext/hg/hooks.py hooks.py] and place it somewhere accessible):

    175 === Per-request synchronization === #PerRequestSync
     182=== Per-request synchronization #PerRequestSync
    176183If 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.

    181 == Migration from a single-repository setup (Subversion) == #Migration
     188== Automatic changeset references in tickets
     189
     190You can automatically add a reference to the changeset as a ticket comment whenever changes are committed to the repository. The description of the commit needs to contain one of the following formulas:
     191 * '''`Refs #123`''' - to reference this changeset in `#123` ticket
     192 * '''`Fixes #123`''' - to reference this changeset and close `#123` ticket with the default status ''fixed''
     193
     194This functionality requires installing a post-commit hook as described in [#ExplicitSync], and enabling the optional commit updater components by adding the following line to the `[components]` section of your [wiki:TracIni#components-section trac.ini], or enabling the components in the //Plugins// admin panel.

     200== Migration from a single-repository setup (Subversion) #Migration
    182201The following procedure illustrates a typical migration from a Subversion single-repository setup to multiple repositories.
    183202
     
    189208 1. Repeat steps 2, 3 and 4 to add other "named" repositories as needed.

    191 == Migration from a single-repository setup (Mercurial) == #MigrationMercurial
     210== Migration from a single-repository setup (Mercurial) #MigrationMercurial
    192211The 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.

    194  1. Upgrade to the latest version of the TracMercurial plugin.
     213 1. Upgrade to the latest version of the [trac:TracMercurial] plugin.
    195214 1. Remove the default repository specification from the `[trac] repository_dir` option.
    196215 1. Add the main repository as a named repository.
     
    198217 1. Repeat step 3 to add other "named" repositories as needed.

    204223You must now use the optional components from `tracopt.ticket.commit_updater.*`, which you can activate through the Plugins panel in the Administrative part of the web interface, or by directly modifying the [TracIni#components-section "[components]"] section in the trac.ini. Be sure to use [#ExplicitSync explicit synchronization] as explained above.
