TracRepositoryAdmin
v4 v5 7 7 * 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. 8 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. 9 10 10 11 11 == Specifying repositories == #Repositories … … 24 24 ||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. || 25 25 ||`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. || 26 ||`name` ||The `name` attribute specifies the leading path element to the repository. || 26 27 ||`type` ||The `type` attribute sets the type of version control system used by the repository. Trac supports Subversion 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. || 27 28 ||`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. || 28 29 29 A repository `name` and one of `alias` or `dir` attributesare mandatory. All others are optional.30 The `name` attribute and one of `alias` or `dir` are mandatory. All others are optional. 30 31 31 32 After adding a repository, the cache for that repository must be re-synchronized once with the `trac-admin $ENV repository resync` command. … … 40 41 The main advantage of specifying repositories in `trac.ini` is that they can be inherited from a global configuration (see the [wiki:TracIni#GlobalConfiguration global configuration] section of TracIni). One drawback is that, due to limitations in the `ConfigParser` class used to parse `trac.ini`, the repository name is always all-lowercase. 41 42 42 The following example defines two Subversion repositories named `project` and `lib`, and a n 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.43 The following example defines two Subversion repositories named `project` and `lib`, and a hidden 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. 43 44 {{{ 44 45 #!ini … … 48 49 project.type = svn 49 50 project.url = http://example.com/svn/project 50 project.hidden = true51 52 51 lib.dir = /var/repos/lib 53 52 lib.description = This is the secondary library code. 54 53 lib.type = svn 55 54 lib.url = http://example.com/svn/lib 56 57 55 .alias = project 56 .hidden = true 58 57 }}} 59 58 Note that `name.alias = target` makes `name` an alias for the `target` repo, not the other way around. … … 86 85 There 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. 87 86 88 === Mercurial Repositories ===89 Please note that at the time of writing, no initial resynchronization or any hooks are necessary for Mercurial repositories - see [trac:#9485] for more information.90 91 87 === Explicit synchronization === #ExplicitSync 92 88 This 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. … … 100 96 The `<repos>` argument can be either a repository name (use "`(default)`" for the default repository) or the path to the repository. 101 97 102 Note 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.103 104 98 The 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`): 105 {{{#!sh 99 {{{ 100 #!sh 106 101 #!/bin/sh 107 export PYTHON_EGG_CACHE="/path/to/dir"108 102 /usr/bin/trac-admin /path/to/env changeset added "$1" "$2" 109 103 }}} 110 104 On Windows (`post-commit.cmd`): 111 {{{#!application/x-dos-batch 105 {{{ 106 #!application/x-dos-batch 112 107 @C:\Python26\Scripts\trac-admin.exe C:\path\to\env changeset added "%1" "%2" 113 108 }}} 114 109 115 110 The post-revprop-change hook for Subversion is very similar. On Unix (`post-revprop-change`): 116 {{{#!sh 111 {{{ 112 #!sh 117 113 #!/bin/sh 118 export PYTHON_EGG_CACHE="/path/to/dir"119 114 /usr/bin/trac-admin /path/to/env changeset modified "$1" "$2" 120 115 }}} 121 116 On Windows (`post-revprop-change.cmd`): 122 {{{#!application/x-dos-batch 117 {{{ 118 #!application/x-dos-batch 123 119 @C:\Python26\Scripts\trac-admin.exe C:\path\to\env changeset modified "%1" "%2" 124 120 }}} 125 121 126 The Unix variants above assume that the user running the Subversion commit has write access to the Trac environment, which is the case in the standard configuration where both the repository and Trac are served by the web server. If you access the repository through another means, for example `svn+ssh://`, you may have to run `trac-admin` with different privileges, for example by using `sudo`.127 128 122 Note that calling `trac-admin` in your Subversion hooks can slow down the commit and log editing operations on the client side. You might want to use the [trac:source:trunk/contrib/trac-svn-hook contrib/trac-svn-hook] script which starts `trac-admin` in an asynchronous way. The script also comes with a number of safety checks and usage advices which should make it easier to set up and test your hooks. There's no equivalent `trac-svn-hook.bat` for Windows yet, but the script can be run by Cygwin's bash. 129 123 130 See the [http://svnbook.red-bean.com/en/1.5/svn.reposadmin.create.html#svn.reposadmin.create.hooks section about hooks] in the Subversion book for more information. Other repository types will require different hook setups. 131 132 Git hooks can be used in the same way for explicit syncing of git repositories. Add the following to `.git/hooks/post-commit`: 133 {{{#!sh 134 REV=$(git rev-parse HEAD) 135 trac-admin /path/to/env changeset added <my-repository> $REV 136 }}} 137 138 For 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 [source:plugins/0.13/mercurial-plugin/tracext/hg/hooks.py hooks.py] and place it somewhere accessible): 139 {{{#!ini 140 [hooks] 141 ; If mercurial-plugin is installed globally 142 commit = python:tracext.hg.hooks.add_changesets 143 changegroup = python:tracext.hg.hooks.add_changesets 144 145 ; If mercurial-plugin is installed in a Trac plugins directory 146 commit = python:/path/to/hooks.py:add_changesets 147 changegroup = python:/path/to/hooks.py:add_changesets 148 149 [trac] 150 env = /path/to/env 151 trac-admin = /path/to/trac-admin 152 }}} 124 See 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.

Remove the default repository specification from the `[trac] repository_dir` option. 164 1. Add the mainrepository as a named repository.136 1. Add the "main" repository as a named repository. 165 137 1. Re-synchronize the main repository. 166 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. 167 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. 168 1. Repeat steps 2, 3 and 4 to add other "named" repositories as needed. 169 170 == Migration from a single-repository setup (Mercurial) == #MigrationMercurial 171 The 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 #9485 for more information. 172 173 1. Upgrade to the latest version of the TracMercurial plugin. 174 1. Remove the default repository specification from the `[trac] repository_dir` option. 175 1. Add the main repository as a named repository. 176 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. 177 1. Repeat step 3 to add other "named" repositories as needed. 138 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. 139 1. Add a hidden alias to the main repository as the default repository. This ensures that all links predating the migration still resolve to the main repository. 140 1. Repeat steps 2, 3 and 4 to add other (named) repositories as needed. 178 141 179 142 == Troubleshooting ==
