    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 is probably a translation available in your language. If you want 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.

    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)
     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)
    2020 * [http://pypi.python.org/pypi/setuptools setuptools], version >= 0.6
    2121 * [http://genshi.edgewall.org/wiki/Download Genshi], version >= 0.6
     
    2525==== For the SQLite database #ForSQLite
    2626
    27 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.
    28 
    29 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.

    3131==== For the PostgreSQL database #ForPostgreSQL
     
    4848=== Optional Dependencies
    4949
    50 ==== Version Control System
    51 
    52 ===== Subversion
    53  * [http://subversion.apache.org/ Subversion], 1.5.x or later and the '''''corresponding''''' Python bindings. Older versions starting from 1.0, like 1.2.4, 1.3.2 or 1.4.2, etc. may still work. For troubleshooting information, check the [trac:TracSubversion#Troubleshooting TracSubversion] page.
     50==== Subversion
     51
     52[http://subversion.apache.org/ Subversion], 1.6.x or later and the '''''corresponding''''' Python bindings.
    5453
    5554There 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. [trac:TracSubversion] points you to [http://alagazam.net Alagazam], which works for me under Python 2.6.)
    5655
    57 Note that Trac '''doesn't''' use [http://pysvn.tigris.org/ PySVN], neither does it work yet with the newer `ctype`-style bindings.
    58 
    59 '''Please note:''' if using Subversion, Trac must be installed on the '''same machine'''. Remote repositories are currently [trac:ticket:493 not supported].
    60 
    61 ===== Git
    62  * [http://git-scm.com/ Git] 1.5.6 or later.
    63 
    64 More information is available on the [trac:TracGit] page.
    65 
    66 ===== Others
    67 
    68 Support for other version control systems is provided via third-parties. See [trac:PluginList#VersionControlSystems] and [trac:VersionControlSystem].
     56For troubleshooting information, see the [trac:TracSubversion#Troubleshooting TracSubversion] page.

     70Support for other version control systems is provided via third-party plugins. See [trac:PluginList#VersionControlSystems] and [trac:VersionControlSystem].
    6971
    7072==== Web Server
     
    7375Alternatively you can configure Trac to run in any of the following environments:
    7476 * [http://httpd.apache.org/ Apache] with
    75    - [http://code.google.com/p/modwsgi/ mod_wsgi], see [wiki:TracModWSGI] and

    7779   - [http://modpython.org/ mod_python 3.5.0], see TracModPython
    7880 * a [http://www.fastcgi.com/ FastCGI]-capable web server (see TracFastCgi)
    7981 * an [http://tomcat.apache.org/connectors-doc/ajp/ajpv13a.html AJP]-capable web
    8082   server (see [trac:TracOnWindowsIisAjp TracOnWindowsIisAjp])
    81  * a FastCGI and FastCGI-to-WSGI gateway (see [trac:TracOnWindowsIisWfastcgi])
     83 * Microsoft IIS with FastCGI and a FastCGI-to-WSGI gateway (see [trac:CookBook/Installation/TracOnWindowsIisWfastcgi IIS with FastCGI])
    8284 * a CGI-capable web server (see TracCgi), '''but usage of Trac as a cgi script
    8385   is highly discouraged''', better use one of the previous options.
     
    8688==== Other Python Packages
    8789
    88  * [http://babel.edgewall.org Babel], version 0.9.5, 0.9.6 or >= 1.3

    9294 * [http://pygments.org Pygments] for
    9395   [TracSyntaxColoring syntax highlighting].
    94    [http://silvercity.sourceforge.net/ SilverCity] and/or
    95    [http://gnu.org/software/enscript/enscript.html Enscript] may still be used
    96    but are deprecated and you really should be using Pygments.
    9796 * [http://pytz.sf.net pytz] to get a complete list of time zones,
    9897   otherwise Trac will fall back on a shorter list from
     
    109108The [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.
    110109
     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
    111112=== Using `easy_install`
    112113Trac can be installed from PyPI or the Subversion repository using [http://pypi.python.org/pypi/setuptools setuptools].
     
    114115A few examples:
    115116
    116  - Install Trac 1.0:
    117    {{{#!sh
    118    easy_install Trac==1.0
    119    }}}
     117 - Install the latest stable version of Trac:
     118 {{{#!sh
     119$ easy_install Trac
     120}}}
    120121 - Install latest development version:
    121    {{{#!sh
    122    easy_install Trac==dev
    123    }}}
     122 {{{#!sh
     123$ easy_install http://download.edgewall.org/trac/Trac-latest-dev.tar.gz
     124}}}
    124125   Note that in this case you won't have the possibility to run a localized version of Trac;
    125126   either use a released version or install from source
    126127
    127 More information can be found on the [trac:setuptools] page.

    175176=== Using installer
    176177
    177 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.

    179180=== Using package manager
    180181
    181 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.
     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.
    182183
    183184=== Advanced `easy_install` Options
     
    185186To install Trac to a custom location, or find out about other advanced installation options, run:
    186187{{{#!sh
    187 easy_install --help
     188$ easy_install --help
    188189}}}
    189190
     
    192193Specifically, you might be interested in:
    193194{{{#!sh
    194 easy_install --prefix=/path/to/installdir
     195$ easy_install --prefix=/path/to/installdir
    195196}}}
    196197or, if installing Trac on a Mac OS X system:
    197198{{{#!sh
    198 easy_install --prefix=/usr/local --install-dir=/Library/Python/2.5/site-packages
    199 }}}
    200 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.
    201 
    202 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.

    204208== Creating a Project Environment
    205209
    206 A [TracEnvironment Trac environment] is the backend 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 other files and directories.

    207211
    208212A new environment is created using [TracAdmin trac-admin]:
     
    211215}}}
    212216
    213 [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.
    214 
    215 Using the default database connection string in particular will always work as long as you have SQLite installed.
    216 For the other [trac:DatabaseBackend database backends] you should plan ahead and already have a database ready to use at this point.
    217 
    218 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.
    219 
    220 Also note that the values you specify here can be changed later by directly editing the [TracIni conf/trac.ini] configuration file.
    221 
    222 {{{#!div style="border: 1pt dotted; margin: 1em"
    223 **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), 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.

    224225}}}
    225226
    226227Finally, 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:
    227228{{{#!sh
    228 $ chown -R apache.apache /path/to/myproject
     229$ chown -R apache:apache /path/to/myproject

     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
    239258=== Running the Standalone Server
    240259
     
    247266{{{#!sh
    248267$ tracd -s --port 8000 /path/to/myproject

    264269
     
    267272Trac provides various options for connecting to a "real" web server:
    268273 - [TracFastCgi FastCGI]
    269  - [wiki:TracModWSGI mod_wsgi]
    270  - [TracModPython mod_python]
     274 - [wiki:TracModWSGI Apache with mod_wsgi]
     275 - [TracModPython Apache with mod_python]
    271276 - //[TracCgi CGI] (should not be used, as the performance is far from optimal)//
    272277
     
    279284There is, however, a bit of a chicken-and-egg problem. The [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:
    280285{{{#!sh
    281 mkdir -p /usr/share/trac/projects/my-project
    282 trac-admin /usr/share/trac/projects/my-project initenv
    283 trac-admin /usr/share/trac/projects/my-project deploy /tmp/deploy
    284 mv /tmp/deploy/* /usr/share/trac
     286$ mkdir -p /usr/share/trac/projects/my-project
     287$ trac-admin /usr/share/trac/projects/my-project initenv
     288$ trac-admin /usr/share/trac/projects/my-project deploy /tmp/deploy
     289$ mv /tmp/deploy/* /usr/share/trac
    285290}}}
    286291Don't forget to check that the web server has the execution right on scripts in the `/usr/share/trac/cgi-bin` directory.
     
    288293==== Mapping Static Resources
    289294
    290 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).
    291 
    292 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.
    293 
    294 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.
    295 
    296 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:
     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:
    297304[[TracAdminHelp(deploy)]]
    298305
    299 The target `<directory>` will then contain an `htdocs` directory with:
    300  - `site/` - a copy of the environment's directory `htdocs/`
    301  - `common/` - the static resources of Trac itself
    302  - `<plugins>/` - one directory for each resource directory managed by the plugins enabled for this environment
    303 
    304 ===== Example: Apache and `ScriptAlias` #ScriptAlias-example
    305 
    306 Assuming the deployment has been done this way:
    307 {{{#!sh
    308 $ trac-admin /var/trac/env deploy /path/to/shared/trac
    309 }}}
    310 
    311 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:
     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:
    312313{{{#!apache
    313314Alias /trac/chrome/common /path/to/trac/htdocs/common
    314315Alias /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
    315330
    316331<Directory "/path/to/www/trac/htdocs">
    317   Order allow,deny
    318   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>
    319341</Directory>
    320342}}}
    321343
    322 If using mod_python, you might want to add this too (otherwise, the alias will be ignored):
     344If using mod_python, add this too, otherwise the alias will be ignored:
    323345{{{#!apache
    324 <Location "/trac/chrome/common/">
     346<Location "/trac/chrome/common">
    325347  SetHandler None
    326348</Location>
    327349}}}
    328350
    329 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.
    330 
    331 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):
     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:
    332352{{{#!apache
    333353Alias /trac/chrome/site /path/to/projectenv/htdocs
    334354
    335355<Directory "/path/to/projectenv/htdocs">
    336   Order allow,deny
    337   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>
    338365</Directory>
    339366}}}
    340367
    341 Alternatively to aliasing `/trac/chrome/common`, you can tell Trac to generate direct links for those static resources (and only those), using the [[TracIni#trac-section| [trac] htdocs_location]] configuration setting:
     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:
    342369{{{#!ini
    343370[trac]
    344371htdocs_location = http://static.example.org/trac-common/
    345372}}}
    346 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]).

    347375
    348376Of 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:

    379 === Enable version control components
    380 
    381 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.
    382 
    383 The version control systems are 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.
    384 
    385 {{{#!ini
    386 tracopt.versioncontrol.svn.* = enabled
    387 }}}
    388 
    389 {{{#!ini
    390 tracopt.versioncontrol.git.* = enabled
    391 }}}
    392 
    393 After enabling the components, repositories can be configured through the //Repositories// admin panel or by editing [TracIni#repositories-section trac.ini]. Automatic changeset references can be inserted as ticket comments by configuring [TracRepositoryAdmin#Automaticchangesetreferencesintickets CommitTicketUpdater].
    394
