    1 = Trac のストレージ - Environment = 
     1= The Trac Environment = 
    22 
    3 Trac はプロジェクトのデータを保存するのに、構造的なディレクトリ構造とデータベースを使用します。 
     3Trac uses a directory structure and a database for storing project data. The directory is referred to as the “environment”. 
    44 
    5 == Environment の作成 == 
     5== Creating an Environment == 
    66 
    7 新しい Trac Environment を作成するには、 [wiki:TracAdmin trac-admin] コマンドを使用します: 
     7A new Trac environment is created using  [TracAdmin#initenv trac-admin's initenv]: 
    88{{{ 
    9 $ trac-admin /path/to/projectenv initenv 
     9$ trac-admin /path/to/myproject initenv 
    1010}}} 
    1111 
    12 [wiki:TracAdmin trac-admin] は プロジェクトの名前、 
    13 データベースに接続するための文字列(以下に説明します)、 
    14 Subversion リポジトリの位置を尋ねます。 
     12`trac-admin` will ask you for the name of the project and the 
     13database connection string (explained below). 
    1514 
    16   ''Note: Environment のディレクトリ配下は、 Web サーバの実行ユーザに書き込みパーミッションを 
    17 与える必要があります。適切なパーミッションの付与を忘れないようにしてください。 
    18 書き込みパーミッションの付与は、 Subversion のリポジトリにも当てはまります。 
    19 ただし、あなたが Subversion リポジトリにバークレー DB のファイルシステムを使用していないならば、 
    20 Trac は読み取りパーミッションしか必要としません。'' 
     15=== Some Useful Tips 
     16 - The user under which the web server runs will require file system write permission to  
     17 the environment directory and all the files inside. Please remember to set 
     18 the appropriate permissions. The same applies to the source code repository,  
     19 although the user under which Trac runs will only require write access to a Subversion repository created with the BDB file system; for other repository types, check the corresponding plugin's documentation.  
     20  
     21 - `initenv`, when using an svn repository, does not imply that trac-admin will perform `svnadmin create` for the specified repository path. You need to perform the `svnadmin create` prior to `trac-admin initenv` if you're creating a new svn repository altogether with a new trac environment, otherwise you will see a message "Warning: couldn't index the repository" when initializing the environment. 
    2122 
    22 == データベースに接続するための文字列 == 
     23 - Non-ascii environment paths are not supported 
     24  
     25 - Also, it seems that project names with spaces can be problematic for authentication (see [trac:#7163]). 
    2326 
    24 バージョン 0.9 以降の Trac では [http://sqlite.org/ SQLite] と 
    25 [http://www.postgresql.org/ PostgreSQL] の両方をデータベースのバックエンドとしてサポートするようになりました。 
    26 通常では SQLite を使用します。たぶんほとんどのプロジェクトにとっては SQLite で十分です。 
    27 データベースファイルは Environment のディレクトリに保存されます。そして、 
    28 [wiki:TracBackup Trac のバックアップ] で Environment の残りの部分 (データベースファイル以外のファイル) と一緒にバックアップすることができます。 
     27 - TracPlugins located in a [TracIni#inherit-section shared plugins folder] that is defined in an [TracIni#GlobalConfiguration inherited configuration] are currently not loaded during creation, and hence, if they need to create extra tables for example, you'll need to [TracUpgrade#UpgradetheTracEnvironment upgrade the environment] before being able to use it. 
    2928 
    30 組み込みの SQLite データベースに接続するための文字列は以下の通りです: 
     29== Database Connection Strings == 
     30 
     31Since version 0.9, Trac supports both [http://sqlite.org/ SQLite] and 
     32[http://www.postgresql.org/ PostgreSQL] database backends.  Preliminary 
     33support for [http://mysql.com/ MySQL] was added in 0.10.  The default is 
     34to use SQLite, which is probably sufficient for most projects. The database 
     35file is then stored in the environment directory, and can easily be  
     36[wiki:TracBackup backed up] together with the rest of the environment. 
     37 
     38=== SQLite Connection String === 
     39The connection string for an SQLite database is: 
    3140{{{ 
    3241sqlite:db/trac.db 
    3342}}} 
     43where `db/trac.db` is the path to the database file within the Trac environment. 
    3444 
    35 もしあなたが、 PostgreSQL を代わりに使用する場合、 
    36 異なる接続用文字列を使用しなければなりません。 
    37 例えば、ユーザ名 `johndoe` でパスワード `letmein` で 
    38 ローカルホストの `trac` と呼ばれるデータベースに接続するには以下のように指定します。 
     45=== PostgreSQL Connection String === 
     46If you want to use PostgreSQL or MySQL instead, you'll have to use a 
     47different connection string. For example, to connect to a PostgreSQL 
     48database on the same machine called `trac`, that allows access to the 
     49user `johndoe` with the password `letmein`, use: 
    3950{{{ 
    4051postgres://johndoe:letmein@localhost/trac 
    4152}}} 
     53''Note that due to the way the above string is parsed, the "/" and "@" characters cannot be part of the password.'' 
    4254 
    43 もし、 PostgreSQL がデフォルト以外のポート番号 (例えば、 9432) で起動しているときはこのようにします: 
     55If PostgreSQL is running on a non-standard port (for example 9342), use: 
    4456{{{ 
    4557postgres://johndoe:letmein@localhost:9342/trac 
    4658}}} 
    4759 
    48 PostgreSQL を使用するとき、`trac-admin initenv` を実行する前に 
    49 データベースを作成しなければいけません。 
     60On UNIX, you might want to select a UNIX socket for the transport, 
     61either the default socket as defined by the PGHOST environment variable: 
     62{{{ 
     63postgres://user:password@/database 
     64}}} 
     65or a specific one: 
     66{{{ 
     67postgres://user:password@/database?host=/path/to/socket/dir 
     68}}} 
    5069 
    51 == ディレクトリ構造 == 
     70Note that with PostgreSQL you will have to create the database before running 
     71`trac-admin initenv`. 
    5272 
    53 一つのプロジェクトの Environment のディレクトリは通常以下に示すファイルとディレクトリから成り立ちます。 
     73See the [http://www.postgresql.org/docs/ PostgreSQL documentation] for detailed instructions on how to administer [http://postgresql.org PostgreSQL]. 
     74Generally, the following is sufficient to create a database user named `tracuser`, and a database named `trac`. 
     75{{{ 
     76createuser -U postgres -E -P tracuser 
     77createdb -U postgres -O tracuser -E UTF8 trac 
     78}}} 
     79When running `createuser` you will be prompted for the password for the user 'tracuser'. This new user will not be a superuser, will not be allowed to create other databases and will not be allowed to create other roles. These privileges are not needed to run a trac instance. If no password is desired for the user, simply remove the `-P` and `-E` options from the `createuser` command.  Also note that the database should be created as UTF8. LATIN1 encoding causes errors trac's use of unicode in trac.  SQL_ASCII also seems to work. 
    5480 
    55  * `README` - Environment について記述したドキュメント。 
    56  * `VERSION` - Environment のバージョン識別情報。 
    57  * `attachments` - 全ての添付ファイルはここに保存されます。 
     81Under some default configurations (debian) one will have run the `createuser` and `createdb` scripts as the `postgres` user.  For example: 
     82{{{ 
     83sudo su - postgres -c 'createuser -U postgres -S -D -R -E -P tracuser' 
     84sudo su - postgres -c 'createdb -U postgres -O tracuser -E UTF8 trac' 
     85}}} 
     86 
     87Trac uses the `public` schema by default but you can specify a different schema in the connection string: 
     88{{{ 
     89postgres://user:pass@server/database?schema=yourschemaname 
     90}}} 
     91 
     92=== MySQL Connection String === 
     93 
     94If you want to use MySQL instead, you'll have to use a 
     95different connection string. For example, to connect to a MySQL 
     96database on the same machine called `trac`, that allows access to the 
     97user `johndoe` with the password `letmein`, the mysql connection string is: 
     98{{{ 
     99mysql://johndoe:letmein@localhost:3306/trac 
     100}}} 
     101 
     102== Source Code Repository == 
     103 
     104Since version 0.12, a single Trac environment can be connected to more than one repository. There are many different ways to connect repositories to an environment, see TracRepositoryAdmin. This page also details the various attributes that can be set for a repository (like `type`, `url`, `description`). 
     105 
     106In Trac 0.12 `trac-admin` no longer asks questions related to repositories. Therefore, by default Trac is not connected to any source code repository, and the ''Browse Source'' toolbar item will not be displayed. 
     107You can also explicitly disable the `trac.versioncontrol.*` components (which are otherwise still loaded) 
     108{{{ 
     109[components] 
     110trac.versioncontrol.* = disabled 
     111}}} 
     112 
     113For some version control systems, it is possible to specify not only the path to the repository, 
     114but also a ''scope'' within the repository. Trac will then only show information 
     115related to the files and changesets below that scope. The Subversion backend for 
     116Trac supports this; for other types, check the corresponding plugin's documentation. 
     117 
     118Example of a configuration for a Subversion repository used as the default repository: 
     119{{{ 
     120[trac] 
     121repository_type = svn 
     122repository_dir = /path/to/your/repository 
     123}}} 
     124 
     125The configuration for a scoped Subversion repository would be: 
     126{{{ 
     127[trac] 
     128repository_type = svn 
     129repository_dir = /path/to/your/repository/scope/within/repos 
     130}}} 
     131 
     132== Directory Structure == 
     133 
     134An environment directory will usually consist of the following files and directories: 
     135 
     136 * `README` - Brief description of the environment. 
     137 * `VERSION` - Contains the environment version identifier. 
     138 * `attachments` - Attachments to wiki pages and tickets are stored here. 
    58139 * `conf` 
    59    * `trac.ini` - メインとなる設定ファイル。詳細は TracIni に記述しています。 
     140   * `trac.ini` - Main configuration file. See TracIni. 
    60141 * `db` 
    61    * `trac.db` - SQLite データベース (SQLite を使用しているならば) 。 
    62  * `plugins` - Environment に固有の [wiki:TracPlugins プラグイン] (Python eggs) 
    63  * `templates` - カスタム (プロジェクトに固有の) テンプレート。 
    64    * `site_css.cs` - カスタム CSS スタイルシート 
    65    * `site_footer.cs` - カスタムフッタ 
    66    * `site_header.cs` - カスタムヘッダ 
    67  * `wiki-macros` - Environment に固有の [wiki:WikiMacros Wiki マクロ] 
     142   * `trac.db` - The SQLite database (if you're using SQLite). 
     143 * `htdocs` - directory containing web resources, which can be referenced in Genshi templates using `/htdocs/site/...` URLs. ''(since 0.11)'' 
     144 * `log` - default directory for log files, if logging is turned on and a relative path is given. 
     145 * `plugins` - Environment-specific [wiki:TracPlugins plugins] (Python eggs or single file plugins, since [trac:milestone:0.10 0.10]) 
     146 * `templates` - Custom Genshi environment-specific templates. ''(since 0.11)'' 
     147   * `site.html` - method to customize header, footer, and style, described in TracInterfaceCustomization#SiteAppearance 
     148 
     149'''Caveat:''' ''don't confuse a Trac environment directory with the source code repository directory.''  
     150 
     151This is a common beginners' mistake. 
     152It happens that the structure for a Trac environment is loosely modelled after the Subversion repository directory  
     153structure, but those are two disjoint entities and they are not and ''must not'' be located at the same place.
