    44Trac 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.
    55
    6 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.
    7 
    8 If you're interested in contributing new translations for other languages or enhance the existing translations, then please have a look at [[trac:TracL10N]].

    10 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.

    14 == Dependencies ==
     14== Dependencies
    1515=== Mandatory Dependencies
    1616To install Trac, the following software packages must be installed:
    1717
    18  * [http://www.python.org/ Python], version >= 2.5 and < 3.0
    19    (note that we dropped the support for Python 2.4 in this release)
    20  * [http://peak.telecommunity.com/DevCenter/setuptools setuptools], version >= 0.6, or better yet, [http://pypi.python.org/pypi/distribute distribute]
    21  * [http://genshi.edgewall.org/wiki/Download Genshi], version >= 0.6 (unreleased version 0.7dev should work as well)
    22 
    23 You also need a database system and the corresponding python bindings.
    24 The database can be either SQLite, PostgreSQL or MySQL.
     18 * [http://www.python.org/ Python], version >= 2.6 and < 3.0
     19   (note that we dropped the support for Python 2.5 in this release)
     20 * [http://pypi.python.org/pypi/setuptools setuptools], version >= 0.6
     21 * [http://genshi.edgewall.org/wiki/Download Genshi], version >= 0.6
     22
     23You also need a database system and the corresponding python bindings. The database can be either SQLite, PostgreSQL or MySQL.
    2524
    2625==== For the SQLite database #ForSQLite
    2726
    28 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).
    29 
    30 However, if you'd like, you can download the latest and greatest version of [[trac:Pysqlite]] from
    31 [http://code.google.com/p/pysqlite/downloads/list google code], where you'll find the Windows
    32 installers or the `tar.gz` archive for building from source:
    33 {{{
    34 $ tar xvfz <version>.tar.gz
    35 $ cd <version>
    36 $ python setup.py build_static install
    37 }}}
    38  
    39 This will download the latest SQLite code and build the bindings.
    40 
    41 SQLite 2.x is no longer supported.
    42 
    43 A known bug PySqlite versions 2.5.2-4 prohibits upgrade of trac databases
    44 from 0.11.x to 0.12. Please use versions 2.5.5 and newer or 2.5.1 and
    45 older. See #9434 for more detail.
    46 
    47 See additional information in [trac:PySqlite PySqlite].
     27As you must be using Python 2.6 or 2.7, you already have the SQLite database bindings bundled with the standard distribution of Python (the `sqlite3` module).
     28
     29Optionally, you may install a newer version of [http://pypi.python.org/pypi/pysqlite pysqlite] than the one provided by the Python distribution. See [trac:PySqlite#ThePysqlite2bindings PySqlite] for details.
    4830
    4931==== For the PostgreSQL database #ForPostgreSQL
     
    5133You need to install the database and its Python bindings:
    5234 * [http://www.postgresql.org/ PostgreSQL], version 8.0 or later
    53  * [http://pypi.python.org/pypi/psycopg2 psycopg2]
     35 * [http://pypi.python.org/pypi/psycopg2 psycopg2], version 2.0 or later
    5436
    5537See [trac:DatabaseBackend#Postgresql DatabaseBackend] for details.
    5638
    57 
    5839==== For the MySQL database #ForMySQL
    5940
    60 Trac can now work quite well with MySQL, provided you follow the guidelines.
     41Trac works well with MySQL, provided you follow the guidelines:
    6142
    6243 * [http://mysql.com/ MySQL], version 5.0 or later
    6344 * [http://sf.net/projects/mysql-python MySQLdb], version 1.2.2 or later
    6445
    65 It is '''very''' important to read carefully the [trac:MySqlDb] page before creating the database.
     46Given the caveats and known issues surrounding MySQL, read carefully the [trac:MySqlDb] page before creating the database.
    6647
    6748=== Optional Dependencies
    6849
    69 ==== Version Control System ====
    70 
    71 ===== Subversion =====
    72  * [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.
    73 
    74 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.)
    75 
    76 Note that Trac '''doesn't''' use [http://pysvn.tigris.org/ PySVN], neither does it work yet with the newer `ctype`-style bindings.
    77 
    78 
    79 '''Please note:''' if using Subversion, Trac must be installed on the '''same machine'''. Remote repositories are currently [trac:ticket:493 not supported].
    80 
    81 
    82 ===== Others =====
    83 
    84 Support for other version control systems is provided via third-parties. See [trac:PluginList] and [trac:VersionControlSystem].
    85 
    86 ==== Web Server ====
    87 A web server is optional because Trac is shipped with a server included, see the [#RunningtheStandaloneServer Running the Standalone Server ] section below.
    88 
    89 Alternatively you configure Trac to run in any of the following environments.
     50==== Subversion
     51
     52[http://subversion.apache.org/ Subversion], 1.6.x or later and the '''''corresponding''''' Python bindings.

     72==== Web Server
     73A web server is optional because Trac is shipped with a server included, see the [#RunningtheStandaloneServer Running the Standalone Server] section below.
     74
     75Alternatively you can configure Trac to run in any of the following environments:
    9076 * [http://httpd.apache.org/ Apache] with
    91    - [http://code.google.com/p/modwsgi/ mod_wsgi], see [wiki:TracModWSGI] and
    92      http://code.google.com/p/modwsgi/wiki/IntegrationWithTrac
    93    - [http://modpython.org/ mod_python 3.3.1], deprecated: see TracModPython)
     77   - [https://github.com/GrahamDumpleton/mod_wsgi mod_wsgi], see [wiki:TracModWSGI] and
     78     [http://code.google.com/p/modwsgi/wiki/IntegrationWithTrac ModWSGI IntegrationWithTrac].
     79   - [http://modpython.org/ mod_python 3.5.0], see TracModPython
    9480 * a [http://www.fastcgi.com/ FastCGI]-capable web server (see TracFastCgi)
    9581 * an [http://tomcat.apache.org/connectors-doc/ajp/ajpv13a.html AJP]-capable web
    9682   server (see [trac:TracOnWindowsIisAjp TracOnWindowsIisAjp])
     83 * Microsoft IIS with FastCGI and a FastCGI-to-WSGI gateway (see [trac:CookBook/Installation/TracOnWindowsIisWfastcgi IIS with FastCGI])
    9784 * a CGI-capable web server (see TracCgi), '''but usage of Trac as a cgi script
    9885   is highly discouraged''', better use one of the previous options.
    9986   
    10087
    101 ==== Other Python Packages ====
    102 
    103  * [http://babel.edgewall.org Babel], version >= 0.9.5,
    104    needed for localization support (unreleased version 1.0dev should work as well)
     88==== Other Python Packages
     89
     90 * [http://babel.edgewall.org Babel], version 0.9.6 or >= 1.3,
     91   needed for localization support
    10592 * [http://docutils.sourceforge.net/ docutils], version >= 0.3.9
    10693   for WikiRestructuredText.
    107  * [http://pygments.pocoo.org Pygments] for
    108    [wiki:TracSyntaxColoring syntax highlighting].
    109    [http://silvercity.sourceforge.net/ SilverCity] and/or
    110    [http://gnu.org/software/enscript/enscript.html Enscript] may still be used
    111    but are deprecated and you really should be using Pygments.
     94 * [http://pygments.org Pygments] for
     95   [TracSyntaxColoring syntax highlighting].
    11296 * [http://pytz.sf.net pytz] to get a complete list of time zones,
    11397   otherwise Trac will fall back on a shorter list from
    11498   an internal time zone implementation.
    11599
    116 '''Attention''': The various available versions of these dependencies are not necessarily interchangable, so please pay attention to the version numbers above. If you are having trouble getting Trac to work please double-check all the dependencies before asking for help on the [trac:MailingList] or [trac:IrcChannel].
    117 
    118 Please refer to the documentation of these packages to find out how they are best installed. In addition, most of the [trac:TracInstallPlatforms platform-specific instructions] also describe the installation of the dependencies. Keep in mind however that the information there ''probably concern older versions of Trac than the one you're installing'' (there are even some pages that are still talking about Trac 0.8!).

     105
     106== Installing Trac
     107
     108The [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.
     109
     110It is assumed throughout this guide that you have elevated permissions as the `root` user or by prefixing commands with `sudo`. The umask `0002` should be used for a typical installation on a Unix-based platform.
     111
    122112=== Using `easy_install`
    123 One way to install Trac is using [http://pypi.python.org/pypi/setuptools setuptools].
    124 With setuptools you can install Trac from the subversion repository;
     113Trac can be installed from PyPI or the Subversion repository using [http://pypi.python.org/pypi/setuptools setuptools].
    125114
    126115A few examples:
    127116
    128  - install Trac 1.0:
    129    {{{
    130    easy_install Trac==1.0
    131    }}}
    132    (NOT YET ENABLED)
    133  - install latest development version 1.0dev:
    134    {{{
    135    easy_install Trac==dev
    136    }}}
     117 - Install the latest stable version of Trac:
     118 {{{#!sh
     119$ easy_install Trac
     120}}}
     121 - Install latest development version:
     122 {{{#!sh
     123$ easy_install http://download.edgewall.org/trac/Trac-latest-dev.tar.gz
     124}}}
    137125   Note that in this case you won't have the possibility to run a localized version of Trac;
    138126   either use a released version or install from source
    139127
     128More information can be found on the [trac:wiki:setuptools setuptools] page.
     129
     130{{{#!div style="border: 1pt dotted; margin: 1em"
     131**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 [#DeployingTrac Deploying Trac].
     132}}}
     133
    140134=== Using `pip`
    141135'pip' is an easy_install replacement that is very useful to quickly install python packages.
    142 To get a trac installation up and running in less than 5 minutes:
     136To get a Trac installation up and running in less than 5 minutes:
    143137
    144138Assuming you want to have your entire pip installation in `/opt/user/trac`
    145139
    146140 -
    147 {{{
    148 pip -E /opt/user/trac install trac psycopg2
     141 {{{#!sh
     142pip install trac psycopg2
    149143}}}
    150144or
    151145 -
    152 {{{
    153 pip -E /opt/user/trac install trac mysql-python
    154 }}}
    155 
    156 Make sure your OS specific headers are available for pip to automatically build PostgreSQL (libpq-dev) or MySQL (libmysqlclient-dev) bindings.
    157 
    158 pip will automatically resolve all dependencies (like Genshi, pygments, etc.) and download the latest packages on pypi.python.org and create a self contained installation in `/opt/user/trac`.
     146 {{{#!sh
     147pip install trac mysql-python
     148}}}
     149

     151
     152pip will automatically resolve all dependencies (like Genshi, pygments, etc.), download the latest packages from pypi.python.org and create a self contained installation in `/opt/user/trac`.
    159153
    160154All commands (`tracd`, `trac-admin`) are available in `/opt/user/trac/bin`. This can also be leveraged for `mod_python` (using `PythonHandler` directive) and `mod_wsgi` (using `WSGIDaemonProcess` directive)
    161155
    162 Additionally, you can install several trac plugins (listed [http://pypi.python.org/pypi?:action=search&term=trac&submit=search here]) through pip.
    163 
    164 
     156Additionally, you can install several Trac plugins (listed [https://pypi.python.org/pypi?:action=browse&show=all&c=516 here]) through pip.
    165157
    166158=== From source
    167 Of course, using the python-typical setup at the top of the source directory also works.
    168 
    169 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).
    170

     159Using 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`) from the [trac:TracDownload] page, or you can get the source directly from the repository.

    175 ''You'll need root permissions or equivalent for this step.''
    176 
    177 This will byte-compile the python source code and install it as an .egg file or folder in the `site-packages` directory
    178 of your Python installation. The .egg will also contain all other resources needed by standard Trac, such as htdocs and templates.
    179 
    180 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.
    181 
    182 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):

    188 === Advanced Options ===
     174Alternatively, 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`).
     175
     176=== Using installer
     177
     178On Windows, Trac can be installed using the exe installers available on the [trac:TracDownload] page. Installers are available for the 32-bit and 64-bit versions of Python. Make sure to use the installer that matches the architecture of your Python installation.
     179
     180=== Using package manager
     181
     182Trac may be available in your platform's package repository. Note however, that the version provided by your package manager may not be the latest release.
     183
     184=== Advanced `easy_install` Options
    189185
    190186To install Trac to a custom location, or find out about other advanced installation options, run:
    191 {{{
     187{{{#!sh
    192188easy_install --help
    193189}}}
    194190

     194{{{#!sh
    199195easy_install --prefix=/path/to/installdir
    200196}}}
    201 or, if installing Trac to a Mac OS X system:
    202 {{{
    203 easy_install --prefix=/usr/local --install-dir=/Library/Python/2.5/site-packages
    204 }}}
    205 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
    206 
    207 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.
    208 
    209 
    210 == Creating a Project Environment ==
    211 
    212 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.

     208== Creating a Project Environment
     209
     210A [TracEnvironment Trac environment] is the backend where Trac stores information like wiki pages, tickets, reports, settings, etc. An environment is a directory that contains a human-readable [TracIni configuration file], and other files and directories.
     211
     212A new environment is created using [TracAdmin trac-admin]:
     213{{{#!sh
    216214$ trac-admin /path/to/myproject initenv
    217215}}}
    218216
    219 [TracAdmin trac-admin] will prompt you for the information it needs to create the environment, such as the name of the project and the [TracEnvironment#DatabaseConnectionStrings database connection string]. If you're not sure what to specify for one of these options, just press `<Enter>` to use the default value.
    220 
    221 Using the default database connection string in particular will always work as long as you have SQLite installed.
    222 For the other [DatabaseBackend database backends] you should plan ahead and already have a database ready to use at this point.
    223 
    224 Since 0.12, Trac doesn't ask for a [TracEnvironment#SourceCodeRepository source code repository] anymore when creating an environment. Repositories can be [TracRepositoryAdmin added] afterward, or the version control support can be disabled completely if you don't need it.
    225 
    226 Also note that the values you specify here can be changed later by directly editing the [TracIni conf/trac.ini] configuration file.
     217[TracAdmin trac-admin] will prompt you for the information it needs to create the environment: the name of the project and the [TracEnvironment#DatabaseConnectionStrings database connection string]. If you're not sure what to specify for any of these options, just press `<Enter>` to use the default value.
     218
     219Using the default database connection string will always work as long as you have SQLite installed. For the other [trac:DatabaseBackend database backends] you should plan ahead and already have a database ready to use at this point.
     220
     221Also note that the values you specify here can be changed later using TracAdmin or directly editing the [TracIni conf/trac.ini] configuration file.
     222
     223{{{#!div style="border: 1pt dotted; margin: 1em"
     224**Filesystem Warning:** 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, or HFS+ on OSX), 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. The best advice is to opt for a platform with sub-second timestamp resolution, regardless of the Trac version.
     225}}}
    227226
    228227Finally, 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:
    229 {{{
    230 # chown -R apache.apache /path/to/myproject
    231 }}}
     228{{{#!sh
     229$ chown -R apache:apache /path/to/myproject
     230}}}
     231
     232The actual username and groupname of the apache server may not be exactly `apache`, and are specified in the Apache configuration file by the directives `User` and `Group` (if Apache `httpd` is what you use).

    238238== Deploying Trac
    239239
    240 === Running the Standalone Server ===
    241 
    242 After having created a Trac environment, you can easily try the web interface by running the standalone server [wiki:TracStandalone tracd]:
    243 {{{
     240{{{#!div style="border: 1pt dotted; margin: 1em"
     241**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.
     242
     243If running `tracd`, the environment variable can be set system-wide or for just the user that runs the `tracd` process. There are several ways to accomplish this in addition to what is discussed here, and depending on the distribution of your OS.
     244
     245To be effective system-wide a shell script with the `export` statement may be added to `/etc/profile.d`. To be effective for a user session the `export` statement may be added to `~/.profile`.
     246{{{#!sh
     247export PKG_RESOURCES_CACHE_ZIP_MANIFESTS=1
     248}}}
     249
     250Alternatively, the variable can be set in the shell before executing `tracd`:
     251{{{#!sh
     252$ PKG_RESOURCES_CACHE_ZIP_MANIFESTS=1 tracd --port 8000 /path/to/myproject
     253}}}
     254
     255If running the Apache web server, !Ubuntu/Debian users should add the `export` statement to `/etc/apache2/envvars`. !RedHat/CentOS/Fedora should can add the `export` statement to `/etc/sysconfig/httpd`.
     256}}}
     257
     258=== Running the Standalone Server
     259
     260After having created a Trac environment, you can easily try the web interface by running the standalone server [TracStandalone tracd]:
     261{{{#!sh
    244262$ tracd --port 8000 /path/to/myproject
    245263}}}
    246264
    247265Then, fire up a browser and visit `http://localhost:8000/`. You should get a simple listing of all environments that `tracd` knows about. Follow the link to the environment you just created, and you should see Trac in action. If you only plan on managing a single project with Trac you can have the standalone server skip the environment list by starting it like this:
    248 {{{
     266{{{#!sh
    249267$ tracd -s --port 8000 /path/to/myproject
    250268}}}
    251269
    252 === Running Trac on a Web Server ===
     270=== Running Trac on a Web Server
    253271
    254272Trac provides various options for connecting to a "real" web server:
    255  - [wiki:TracFastCgi FastCGI]
    256  - [wiki:TracModWSGI mod_wsgi]
    257  - //[wiki:TracModPython mod_python] (no longer recommended, as mod_python is not actively maintained anymore)//
    258  - //[wiki:TracCgi CGI] (should not be used, as the performance is far from optimal)//
     273 - [TracFastCgi FastCGI]
     274 - [wiki:TracModWSGI Apache with mod_wsgi]
     275 - [TracModPython Apache with mod_python]
     276 - //[TracCgi CGI] (should not be used, as the performance is far from optimal)//
    259277
    260278Trac 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.
    261279
    262 ==== Generating the Trac cgi-bin directory ==== #cgi-bin
    263 
    264 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].
    265 
    266 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:

    272290}}}
    273 
    274 
    275 ==== Mapping Static Resources ====
    276 
    277 Out of the box, Trac will pass static resources such as style sheets or images through itself. For anything but a tracd only based deployment, this is far from optimal as the web server could be set up to directly serve those static resources (for CGI setup, this is '''highly undesirable''' and will cause abysmal performance).
    278 
    279 Web servers such as [http://httpd.apache.org/ Apache] allow you to create “Aliases” to resources, giving them a virtual URL that doesn't necessarily reflect the layout of the servers file system. We also can map requests for static resources directly to the directory on the file system, avoiding processing these requests by Trac itself.
    280 
    281 There are two primary URL paths for static resources - `/chrome/common` and `/chrome/site`. Plugins can add their own resources, usually accessible by `/chrome/<plugin>` path, so its important to override only known paths and not try to make universal `/chrome` alias for everything.
    282 
    283 Note that in order to get those static resources on the filesystem, you need first to extract the relevant resources from Trac using the [TracAdmin trac-admin]` <environment> deploy` command:
     291Don't forget to check that the web server has the execution right on scripts in the `/usr/share/trac/cgi-bin` directory.
     292
     293==== Mapping Static Resources
     294
     295Without additional configuration, Trac will handle requests for static resources such as stylesheets and images. For anything other than a TracStandalone deployment, this is not optimal as the web server can be set up to directly serve the static resources. For CGI setup, this is '''highly undesirable''' as it causes abysmal performance.
     296
     297Web servers such as [http://httpd.apache.org/ Apache] allow you to create //Aliases// to resources, giving them a virtual URL that doesn't necessarily reflect their location on the file system. We can map requests for static resources directly to directories on the file system, to avoid Trac processing the requests.
     298
     299There are two primary URL paths for static resources: `/chrome/common` and `/chrome/site`. Plugins can add their own resources, usually accessible at the `/chrome/<plugin>` path.
     300
     301A single `/chrome` alias can used if the static resources are extracted for all plugins. This means that the `deploy` command must be executed after installing or updating a plugin that provides static resources, or after modifying resources in the `$env/htdocs` directory. This is probably appropriate for most installations but may not be what you want if, for example, you wish to upload plugins through the //Plugins// administration page.
     302
     303The resources are extracted using the [TracAdmin trac-admin]` <environment> deploy` command:
    284304[[TracAdminHelp(deploy)]]
    285305
    286 The target `<directory>` will then contain an `htdocs` directory with:
    287  - `site/` - a copy of the environment's directory `htdocs/`
    288  - `common/` - the static resources of Trac itself
    289  - `<plugins>/` - one directory for each resource directory managed by the plugins enabled for this environment
    290 
    291 ===== Example: Apache and `ScriptAlias` ===== #ScriptAlias-example
    292 
    293 Assuming the deployment has been done this way:
    294 {{{
    295 $ trac-admin /var/trac/env deploy /path/to/trac/htdocs/common
    296 }}}
    297 
    298 Add the following snippet to Apache configuration ''before'' the `ScriptAlias` or `WSGIScriptAlias` (which map all the other requests to the Trac application), changing paths to match your deployment:
    299 {{{
     306The target `<directory>` will contain an `htdocs` directory with:
     307 - `common/` - the static resources of Trac
     308 - `site/` - a copy of the environment's `htdocs/` directory
     309 - `shared` - the static resources shared by multiple Trac environments, with a location defined by the `[inherit]` `htdocs_dir` option
     310 - `<plugin>/` - one directory for each resource directory provided by the plugins enabled for this environment
     311
     312The example that follows will create a single `/chrome` alias. If that isn't the correct approach for your installation you simply need to create more specific aliases:
     313{{{#!apache
    300314Alias /trac/chrome/common /path/to/trac/htdocs/common
    301315Alias /trac/chrome/site /path/to/trac/htdocs/site
     316Alias /trac/chrome/shared /path/to/trac/htdocs/shared
     317Alias /trac/chrome/<plugin> /path/to/trac/htdocs/<plugin>
     318}}}
     319
     320===== Example: Apache and `ScriptAlias` #ScriptAlias-example
     321
     322Assuming the deployment has been done this way:
     323{{{#!sh
     324$ trac-admin /var/trac/env deploy /path/to/shared/trac
     325}}}
     326
     327Add the following snippet to Apache configuration, changing paths to match your deployment. The snippet must be placed ''before'' the `ScriptAlias` or `WSGIScriptAlias` directive, because those directives map all requests to the Trac application:
     328{{{#!apache
     329Alias /trac/chrome /path/to/trac/htdocs
    302330
    303331<Directory "/path/to/www/trac/htdocs">
    304   Order allow,deny
    305   Allow from all
     332  # For Apache 2.2
     333  <IfModule !mod_authz_core.c>
     334    Order allow,deny
     335    Allow from all
     336  </IfModule>
     337  # For Apache 2.4
     338  <IfModule mod_authz_core.c>
     339    Require all granted
     340  </IfModule>
    306341</Directory>
    307342}}}
    308343
    309 If using mod_python, you might want to add this too (otherwise, the alias will be ignored):
    310 {{{
    311 <Location "/trac/chrome/common/">
     344If using mod_python, add this too, otherwise the alias will be ignored:
     345{{{#!apache
     346<Location "/trac/chrome/common">
    312347  SetHandler None
    313348</Location>
    314349}}}
    315350
    316 Note that we mapped `/trac` part of the URL to the `trac.*cgi` script, and the path `/trac/chrome/common` is the path you have to append to that location to intercept requests to the static resources.
    317 
    318 Similarly, if you have static resources in a project's `htdocs` directory (which is referenced by `/trac/chrome/site` URL in themes), you can configure Apache to serve those resources (again, put this ''before'' the `ScriptAlias` or `WSGIScriptAlias` for the .*cgi scripts, and adjust names and locations to match your installation):
    319 {{{
     351Alternatively, if you wish to serve static resources directly from your project's `htdocs` directory rather than the location to which the files are extracted with the `deploy` command, you can configure Apache to serve those resources. Again, put this ''before'' the `ScriptAlias` or `WSGIScriptAlias` for the .*cgi scripts, and adjust names and locations to match your installation:
     352{{{#!apache
    320353Alias /trac/chrome/site /path/to/projectenv/htdocs
    321354
    322355<Directory "/path/to/projectenv/htdocs">
    323   Order allow,deny
    324   Allow from all
     356  # For Apache 2.2
     357  <IfModule !mod_authz_core.c>
     358    Order allow,deny
     359    Allow from all
     360  </IfModule>
     361  # For Apache 2.4
     362  <IfModule mod_authz_core.c>
     363    Require all granted
     364  </IfModule>
    325365</Directory>
    326366}}}
    327367
    328 Alternatively to aliasing `/trac/chrome/common`, you can tell Trac to generate direct links for those static resources (and only those), using the [[wiki:TracIni#trac-section| [trac] htdocs_location]] configuration setting:
    329 {{{
     368Another alternative to aliasing `/trac/chrome/common` is having Trac generate direct links for those static resources (and only those), using the [[TracIni#trac-section| [trac] htdocs_location]] configuration setting:
     369{{{#!ini
    330370[trac]
    331371htdocs_location = http://static.example.org/trac-common/
    332372}}}
    333 Note that this makes it easy to have a dedicated domain serve those static resources (preferentially [http://code.google.com/speed/page-speed/docs/request.html#ServeFromCookielessDomain cookie-less]).
     373
     374Note that this makes it easy to have a dedicated domain serve those static resources, preferentially cookie-less.
    334375
    335376Of course, you still need to make the Trac `htdocs/common` directory available through the web server at the specified URL, for example by copying (or linking) the directory into the document root of the web server:
    336 {{{
     377{{{#!sh
    337378$ ln -s /path/to/trac/htdocs/common /var/www/static.example.org/trac-common
    338379}}}
    339380
    340 
    341 ==== Setting up the Plugin Cache ====
    342 
    343 Some Python plugins need to be extracted to a cache directory. By default the cache resides in the home directory of the current user. When running Trac on a Web Server as a dedicated user (which is highly recommended) who has no home directory, this might prevent the plugins from starting. To override the cache location you can set the PYTHON_EGG_CACHE environment variable. Refer to your server documentation for detailed instructions on how to set environment variables.
    344 
    345 == Configuring Authentication ==
    346 
    347 Trac uses HTTP authentication. You'll need to configure your webserver to request authentication when the `.../login` URL is hit (the virtual path of the "login" button). Trac will automatically pick the REMOTE_USER variable up after you provide your credentials. Therefore, all user management goes through your web server configuration. Please consult the documentation of your web server for more info.

    366 
    367 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:
    368  * '''`Refs #123`''' - to reference this changeset in `#123` ticket
    369  * '''`Fixes #123`''' - to reference this changeset and close `#123` ticket with the default status ''fixed''
    370 
    371 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.
