    4 Trac EnvironmentはTracの新しいバージョンで使用する前に、アップグレードしなければならない
    5 場合があります。このドキュメントはTrac Environmentをアップグレードするのに必要な手順を
    6 説明します。
     4A Trac environment sometimes needs to be upgraded before it can be used with a new version of Trac. This document describes the steps necessary to upgrade an environment.
    75
    8 == バージョン0.7.x から バージョン0.8 ==
     6 '''Note''': ''Environment upgrades are not necessary for minor version releases unless otherwise noted. For example, there's no need to upgrade a Trac environment created with (or upgraded) 0.8.0 when installing 0.8.4 (or any other 0.8.x release).''
    97
    10 データベースのスキーマがバージョン0.7.xから0.8の間で変更されました。
    11 既存のTrac Environmentは0.8で使用する前にアップグレードしなければなりません。
     8== General Instructions ==
    129
    13 以下のコマンドで自動的にアップグレードされます。
     10Typically, there are four steps involved in upgrading to a newer version of Trac:
     11
     12=== Update the Trac Code ===
     13
     14Get the new version of Trac, either by downloading an offical release package or by checking it out from the [http://projects.edgewall.com/trac/wiki/SubversionRepository Subversion repository].
     15
     16If you have a source distribution, you need to run
    1417{{{
    15  $ trac-admin /path/to/projectenv upgrade
     18python setup.py install
    1619}}}
    1720
    18 Trac EnvironmentはデフォルトのWikiページのセットで作成されます。
    19 最新のドキュメントと追加の機能を得るためにTracをアップグレードする度に、
    20 既存のTrac EnvironmentのWikiページを最新版にすることが推奨されます。
    21 以下のコマンドはWikiページ更新実施コマンドです:
     21to install the new version. If you've downloaded the Windows installer, you execute it, and so on.
     22
     23In any case, if you're doing a major version upgrade (such as from 0.8 to 0.9), it is ''highly'' recommended that you first remove the existing Trac code. To do this, you need to delete the `trac` directory from the Python `lib/site-packages` directory. You may also want to remove the Trac `cgi-bin`, `htdocs` and `templates` directories that are commonly found in a directory called `share/trac` (the exact location depends on your platform).
     24
     25=== Upgrade the Trac Environment ===
     26
     27Unless noted otherwise, upgrading between major versions (such as 0.8 and 0.9) involves changes to the database schema, and possibly the layout of the [wiki:TracEnvironment environment directory]. Fortunately, Trac provides automated upgrade scripts to ease the pain. These scripts are run via [wiki:TracAdmin trac-admin]:
    2228{{{
    23  $ trac-admin /path/to/projectenv wiki upgrade
     29trac-admin /path/to/projenv upgrade
    2430}}}
    2531
    26 0.8では付随的なパーミッションを要求する新しい機能が加わりました。
    27 新規にインストールを行なった場合は、anonymousにROADMAP_VIEWとMAILSTONE_VIEWパーミッションがデフォルトで与えられますが、
    28 既存のtrac をアップグレードしたときは、
    29 これらのパーミッションを手動で与えなければなりません。:
     32This command will do nothing if the environment is already up-to-date.
     33
     34Note that if you are using a PostgreSQL database, this command will fail with the message that the environment can only be backed up when you use an SQLite database. This means that you will have to backup the repository and the database manually. Then, to perform the actual upgrade, run:
     35{{{
     36trac-admin /path/to/projenv upgrade --no-backup
     37}}}
     38
     39=== Update the Trac Documentation ===
     40
     41Every [wiki:TracEnvironment Trac environment] includes a copy of the Trac documentation for the installed version. As you probably want to keep the included documentation in sync with the installed version of Trac, [wiki:TracAdmin trac-admin] provides a command to upgrade the documentation:
     42{{{
     43trac-admin /path/to/projenv wiki upgrade
     44}}}
     45
     46Note that this procedure will of course leave your `WikiStart` page intact.
     47
     48=== Restart the Web Server ===
     49
     50In order to reload the new Trac code you will need to restart your web server (note this is not necessary for [wiki:TracCgi CGI]).
     51
     52== Specific Versions ==
     53
     54The following sections discuss any extra actions that may need to be taken to upgrade to specific versions of Trac.
     55
     56== From 0.9-beta to 0.9 ==
     57
     58If inclusion of the static resources (style sheets, javascript, images) is not working, check the value of the `htdocs_location` in trac.ini. For [wiki:TracModPython mod_python], [wiki:TracStandalone Tracd] and [wiki:TracFastCgi FastCGI], you can simply remove the option altogether. For [wiki:TracCgi CGI], you should fix it to point to the URL you mapped the Trac `htdocs` directory to (although you can also remove it and then [wiki:TracCgi#MappingStaticResources map the static resources]). If you're still having problems after removing the option, check the paths in the `trac/siteconfig.py` file and fix them if they're incorrect.
     59
     60If you've been using plugins with a beta release of Trac 0.9, or have disabled some of the built-in components, you might have to update the rules for disabling/enabling components in [wiki:TracIni trac.ini]. In particular, globally installed plugins now need to be enabled explicitly. See TracPlugins and TracIni for more information.
     61
     62If you want to enable the display of all ticket changes in the timeline (the “Ticket Details” option), you now have to explicitly enable that in [wiki:TracIni trac.ini], too:
     63
     64{{{
     65[timeline]
     66ticket_show_details = true
     67}}}
     68
     69== From 0.8.x to 0.9 ==
     70
     71[wiki:TracModPython mod_python] users will also need to change the name of the mod_python handler in the Apache HTTPD configuration:
     72{{{
     73   from: PythonHandler trac.ModPythonHandler
     74   to:   PythonHandler trac.web.modpython_frontend
     75}}}
     76
     77If you have [http://initd.org/tracker/pysqlite PySQLite] 2.x installed, Trac will now try to open your SQLite database using the SQLite 3.x file format. The database formats used by SQLite 2.8.x and SQLite 3.x are incompatible. If you get an error like ''“file is encrypted or is not a database”'' after upgrading, then you must convert your database file.
     78
     79To do this, you need to have both SQLite 2.8.x and SQLite 3.x installed (they have different filenames so can coexist on the same system). Then use the following commands:
     80{{{
     81 $ mv trac.db trac2.db
     82 $ sqlite trac2.db .dump | sqlite3 trac.db
     83}}}
     84
     85After testing that the conversion was successful, the `trac2.db` file can be deleted. For more information on the SQLite upgrade see http://www.sqlite.org/version3.html.
     86
     87== From 0.7.x to 0.8 ==
     88
     890.8 adds a new roadmap feature which requires additional permissions. While a
     90fresh installation will by default grant ROADMAP_VIEW and MILESTONE_VIEW
     91permissions to anonymous, these permissions have to be granted manually when
     92upgrading:
    3093{{{
    3194 $ trac-admin /path/to/projectenv permission add anonymous MILESTONE_VIEW
