 …
 Trac is written in the Python programming language and needs a database, [http://sqlite.org/ SQLite], [http://www.postgresql.org/ PostgreSQL], or [http://mysql.com/ MySQL]. For HTML rendering, Trac uses the [http://genshi.edgewall.org Genshi] templating system.
 Since version 0.12, Trac can also be localized, and there's probably a translation available for your language. If you want to be able to use the Trac interface in other languages, then make sure you have installed the optional package [#OtherPythonPackages Babel]. Pay attention to the extra steps for localization support in the [#InstallingTrac Installing Trac] section below. Lacking Babel, you will only get the default English version, as usual.
 If you're interested in contributing new translations for other languages or enhance the existing translations, then please have a look at [trac:wiki:TracL10N TracL10N].
 What follows are generic instructions for installing and setting up Trac and its requirements. While you may find instructions for installing Trac on specific systems at [trac:TracInstallPlatforms TracInstallPlatforms] on the main Trac site, please be sure to '''first read through these general instructions''' to get a good understanding of the tasks involved.

 ==== For the SQLite database #ForSQLite
+As you must be using Python 2.5, 2.6 or 2.7, you already have the SQLite database bindings bundled with the standard distribution of Python (the `sqlite3` module).
+However, if you'd like, you can download the latest and greatest version of [[trac:PySqlite]] from
+[http://code.google.com/p/pysqlite/downloads/list google code], where you'll find the Windows
+installers or the `tar.gz` archive for building from source:
+{{{#!sh
+$ tar xvfz <version>.tar.gz
+$ cd <version>
+$ python setup.py build_static install
+}}}
+This will download the latest SQLite code and build the bindings.
+SQLite 2.x is no longer supported.
+A known bug in PySqlite versions 2.5.2-4 prohibits upgrades of Trac databases
+from 0.11.x to 0.12. Please use versions 2.5.5 and newer or 2.5.1 and
+older. See #9434 for more detail.
+See additional information in [trac:PySqlite PySqlite].
+As you must be using Python 2.5, 2.6 or 2.7, you already have the SQLite database bindings bundled with the standard distribution of Python: the `sqlite3` module.
+Optionally, you may install a newer version of [pypi:pysqlite pysqlite] than the one provided by the Python distribution. See [trac:PySqlite#ThePysqlite2bindings PySqlite] for details.
 ==== For the PostgreSQL database #ForPostgreSQL

 === Optional Dependencies
 …
 ===== Subversion
  * [http://subversion.apache.org/ Subversion], 1.5.x or 1.6.x and the '''''corresponding''''' Python bindings. Older versions starting from 1.0, like 1.2.4, 1.3.2 or 1.4.2, etc. should still work. For troubleshooting information, check the [trac:TracSubversion#Troubleshooting TracSubversion] page.
 There are [http://subversion.apache.org/packages.html pre-compiled SWIG bindings] available for various platforms. (Good luck finding precompiled SWIG bindings for any Windows package at that listing. TracSubversion points you to [http://alagazam.net Algazam], which works for me under Python 2.6.)

 == Installing Trac
+The [TracAdmin trac-admin] command-line tool, used to create and maintain [TracEnvironment project environments], as well as the [TracStandalone tracd] standalone server are installed along with Trac. There are several methods for installing Trac.
 === Using `easy_install`
+One way to install Trac is using [http://pypi.python.org/pypi/setuptools setuptools].
+With setuptools you can install Trac from the Subversion repository;
+Trac can be installed from PyPI or the Subversion repository using [http://pypi.python.org/pypi/setuptools setuptools].
 A few examples:

    either use a released version or install from source
+More information can be found on the [trac:setuptools] page.
 {{{#!div style="border: 1pt dotted; margin: 1em"
 **Setuptools Warning:** If the version of your setuptools is in the range 5.4 through 5.6, the environment variable `PKG_RESOURCES_CACHE_ZIP_MANIFESTS` must be set in order to avoid significant performance degradation. More information may be found in the sections on [#RunningtheStandaloneServer Running The Standalone Server] and [#RunningTraconaWebServer Running Trac on a Web Server].

 === From source
+Of course, using the python-typical setup at the top of the source directory also works.
+You can obtain the source for a .tar.gz or .zip file corresponding to a release (e.g. `Trac-1.0.tar.gz`), or you can get the source directly from the repository (see [trac:SubversionRepository] for details).

 This will byte-compile the Python source code and install it as an .egg file or folder in the `site-packages` directory
 of your Python installation. The .egg will also contain all other resources needed by standard Trac, such as `htdocs` and `templates`.
-The script will also install the [wiki:TracAdmin trac-admin] command-line tool, used to create and maintain [wiki:TracEnvironment project environments], as well as the [wiki:TracStandalone tracd] standalone server.
 If you install from source and want to make Trac available in other languages, make sure Babel is installed. Only then, perform the `install` (or simply redo the `install` once again afterwards if you realize Babel was not yet installed):
 {{{#!sh

 Alternatively, you can run `bdist_egg` and copy the .egg from `dist/` to the place of your choice, or you can create a Windows installer (`bdist_wininst`).
+=== Advanced Options
+=== Using installer
+On Windows Trac can be installed using the exe installers available on the [trac:TracDownload] page. Installers are available for the 32 and 64 bit versions of Python. Make sure to use the installer that matches the architecture of your Python installation.
+=== Using package manager
+Trac may be available in the package repository for your platform. Note however, that the version provided by the package manager may not be the latest release.
+=== Advanced `easy_install` Options
 To install Trac to a custom location, or find out about other advanced installation options, run:
 …
 easy_install --prefix=/usr/local --install-dir=/Library/Python/2.5/site-packages
 }}}
 Note: If installing on Mac OS X 10.6 running {{{ easy_install http://svn.edgewall.org/repos/trac/trunk }}} will install into {{{ /usr/local }}} and {{{ /Library/Python/2.6/site-packages }}} by default.
+Note: If installing on Mac OS X 10.6 running {{{ easy_install http://svn.edgewall.org/repos/trac/trunk }}} will install into {{{ /usr/local }}} and {{{ /Library/Python/2.5/site-packages }}} by default.
 The above will place your `tracd` and `trac-admin` commands into `/usr/local/bin` and will install the Trac libraries and dependencies into `/Library/Python/2.5/site-packages`, which is Apple's preferred location for third-party Python application installations.
 == Creating a Project Environment
 A [TracEnvironment Trac environment] is the backend storage where Trac stores information like wiki pages, tickets, reports, settings, etc. An environment is basically a directory that contains a human-readable [TracIni configuration file], and various other files and directories.
 A new environment is created using [wiki:TracAdmin trac-admin]:

 Since 0.12, Trac doesn't ask for a [TracEnvironment#SourceCodeRepository source code repository] anymore when creating an environment. Repositories can be [TracRepositoryAdmin added] afterwards, and support for specific version control systems is disabled by default.
 …
 Also note that the values you specify here can be changed later by directly editing the [TracIni conf/trac.ini] configuration file.
+When selecting the location of your environment, make sure that the filesystem on which the environment directory resides supports sub-second timestamps (i.e. **not** `ext2` or `ext3` on Linux), as the modification time of the `conf/trac.ini` file will be monitored to decide whether an environment restart is needed or not. A too coarse-grained timestamp resolution may result in inconsistencies in Trac < 1.0.2 (though the best advice is to opt for a platform with sub-second timestamp resolution when possible regardless of the version of Trac you are running).

 Finally, make sure the user account under which the web front-end runs will have '''write permissions''' to the environment directory and all the files inside. This will be the case if you run `trac-admin ... initenv` as this user. If not, you should set the correct user afterwards. For example on Linux, with the web server running as user `apache` and group `apache`, enter:

 Trac provides various options for connecting to a "real" web server:
  - [wiki:TracFastCgi FastCGI]

  - [wiki:TracModWSGI mod_wsgi]

 Trac also supports [trac:TracOnWindowsIisAjp AJP] which may be your choice if you want to connect to IIS. Other deployment scenarios are possible: [trac:TracNginxRecipe nginx], [http://projects.unbit.it/uwsgi/wiki/Example#Traconapacheinasub-uri uwsgi], [trac:TracOnWindowsIisIsapi Isapi-wsgi] etc.
 …
 ==== Generating the Trac cgi-bin directory #cgi-bin
 In order for Trac to function properly with FastCGI you need to have a `trac.fcgi` file and for mod_wsgi a `trac.wsgi` file. These are Python scripts which load the appropriate Python code. They can be generated using the `deploy` option of [wiki:TracAdmin trac-admin].
 There is, however, a bit of a chicken-and-egg problem. The [wiki:TracAdmin trac-admin] command requires an existing environment to function, but complains if the deploy directory already exists. This is a problem, because environments are often stored in a subdirectory of the deploy. The solution is to do something like this:

 == Granting admin rights to the admin user
 …
 Support for version control systems is provided by optional components in Trac and the components are disabled by default //(since 1.0)//. Subversion and Git must be explicitly enabled if you wish to use them. See TracRepositoryAdmin for more details.
 The components 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.

 }}}
+After enabling the components, repositories can be configured through the "Repositories" admin panel or by editing [TracIni#repositories-section trac.ini].
+=== Automatic reference to the SVN changesets in Trac tickets
+You can configure SVN to automatically add a reference to the changeset into the ticket comments, whenever changes are committed to the repository. The description of the commit needs to contain one of the following formulas:
+ * '''`Refs #123`''' - to reference this changeset in `#123` ticket
+ * '''`Fixes #123`''' - to reference this changeset and close `#123` ticket with the default status ''fixed''
+This functionality requires a post-commit hook to be installed as described in [wiki:TracRepositoryAdmin#ExplicitSync TracRepositoryAdmin], 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.
+{{{#!ini

 === Using Trac
 …
 Once you have your Trac site up and running, you should be able to create tickets, view the timeline, browse your version control repository if configured, etc.
 Keep in mind that //anonymous// (not logged in) users can by default access only a few of the features, in particular they will have a read-only access to the resources. You will need to configure authentication and grant additional [wiki:TracPermissions permissions] to authenticated users to see the full set of features.
