    410Trac 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.
    511
    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 **first** have installed the optional package [#OtherPythonPackages Babel]. Lacking Babel, you will only get the default English version, as usual. If you install Babel later on, you will need to re-install Trac.

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.

    14 == Dependencies ==
     20== Dependencies
    1521=== Mandatory Dependencies
    1622To install Trac, the following software packages must be installed:
    1723
    18  * [http://www.python.org/ Python], version >= 2.4 and < 3.0
    19    //(note that we dropped the support for Python 2.3 in this release and that this will be the last Trac release supporting Python 2.4)//
     24 * [http://www.python.org/ Python], version >= 2.5 and < 3.0
     25   (note that we dropped the support for Python 2.4 in this release)
    2026 * [http://peak.telecommunity.com/DevCenter/setuptools setuptools], version >= 0.6
    21  * [http://genshi.edgewall.org/wiki/Download Genshi], version >= 0.6 (but < 0.7dev, i.e. don't use Genshi trunk)
     27 * [http://genshi.edgewall.org/wiki/Download Genshi], version >= 0.6
    2228
    2329You also need a database system and the corresponding python bindings.
     
    2632==== For the SQLite database #ForSQLite
    2733
    28 If you're using Python 2.5 or 2.6, you already have everything you need.
    29 
    30 If you're using Python 2.4 and need pysqlite, you can download from
    31 [http://code.google.com/p/pysqlite/downloads/list google code] the Windows installers or the tar.gz archive for building from source:
    32 {{{
     34As 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).
     35
     36However, if you'd like, you can download the latest and greatest version of [[trac:PySqlite]] from
     37[http://code.google.com/p/pysqlite/downloads/list google code], where you'll find the Windows
     38installers or the `tar.gz` archive for building from source:
     39{{{#!sh
    3340$ tar xvfz <version>.tar.gz
    3441$ cd <version>
     
    3643}}}
    3744 
    38 This will extract the SQLite code and build the bindings.
    39 
    40 To install SQLite, your system may require the development headers. Without these you will get various GCC related errors when attempting to build:
    41 
    42 {{{
    43 $ apt-get install libsqlite3-dev
    44 }}}
    45 
    46 SQLite 2.x is no longer supported, and neither is !PySqlite 1.1.x.
    47 
    48 A known bug !PySqlite versions 2.5.2-4 prohibits upgrade of trac databases
     45This will download the latest SQLite code and build the bindings.
     46
     47SQLite 2.x is no longer supported.
     48
     49A known bug in PySqlite versions 2.5.2-4 prohibits upgrades of Trac databases
    4950from 0.11.x to 0.12. Please use versions 2.5.5 and newer or 2.5.1 and
    50 older. See [trac:#9434] for more detail.

     53See additional information in [trac:PySqlite PySqlite].
    5354
    5455==== For the PostgreSQL database #ForPostgreSQL
     
    5657You need to install the database and its Python bindings:
    5758 * [http://www.postgresql.org/ PostgreSQL], version 8.0 or later
    58  * [http://pypi.python.org/pypi/psycopg2 psycopg2]
     59 * [http://pypi.python.org/pypi/psycopg2 psycopg2], version 2.0 or later
    5960
    6061See [trac:DatabaseBackend#Postgresql DatabaseBackend] for details.
     
    7273=== Optional Dependencies
    7374
    74 ==== Version Control System ====
    75 
    76 ===== Subversion =====
    77 
    78 [http://subversion.apache.org/ Subversion] 1.5.x or 1.6.x and the '''''corresponding''''' Python bindings.
    79 
    80 There are [http://subversion.apache.org/packages.html pre-compiled SWIG bindings] available for various platforms. See also the TracSubversion page for details about Windows packages.
    81 
    82 Older versions starting from 1.4.0, etc. should still work. For troubleshooting information, check the [trac:TracSubversion#Troubleshooting TracSubversion] page. Versions prior to 1.4.0 won't probably work since trac uses svn core functionality (e.g. svn_path_canonicalize) that is not implemented in the python swig wrapper in svn <= 1.3.x (although it exists in the svn lib itself).
     75==== Version Control System
     76
     77===== Subversion
     78 * [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.
     79
     80There 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.)
    8381
    8482Note that Trac '''doesn't''' use [http://pysvn.tigris.org/ PySVN], neither does it work yet with the newer `ctype`-style bindings.
    8583
    86 '''Please note:''' if using Subversion, Trac must be installed on the '''same machine'''. Remote repositories are currently [trac:#493 not supported].
    87 
    88 
    89 ===== Others =====

    9190Support for other version control systems is provided via third-parties. See [trac:PluginList] and [trac:VersionControlSystem].
    9291
    93 ==== Web Server ====
    94 A web server is optional because Trac is shipped with a server included, see the [#RunningtheStandaloneServer Running the Standalone Server ] section below.
    95 
    96 Alternatively you configure Trac to run in any of the following environments.

    125123
    126124Please 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!).

    129 == Installing Trac ==
     127== Installing Trac
    130128=== Using `easy_install`
    131129One way to install Trac is using [http://pypi.python.org/pypi/setuptools setuptools].
    132 With setuptools you can install Trac from the subversion repository;
     130With setuptools you can install Trac from the Subversion repository;
    133131
    134132A few examples:
    135133
    136  - first install of the latest stable version Trac 0.12.3, with i18n support:
    137    {{{
    138    easy_install Babel==0.9.5
    139    easy_install Trac==0.12
     134 - Install Trac 1.0:
     135   {{{#!sh
     136   easy_install Trac==1.0
    140137   }}}
    141    ''It's very important to run the two `easy_install` commands separately, otherwise the message catalogs won't be generated.''
    142 
    143  - upgrade to the latest stable version of Trac:
    144    {{{
    145    easy_install -U Trac
     138 - Install latest development version:
     139   {{{#!sh
     140   easy_install Trac==dev
    146141   }}}
    147 
    148  - upgrade to the latest trunk development version:
    149    {{{
    150    easy_install -U Trac==dev
    151    }}}
    152 
    153 For upgrades, reading the TracUpgrade page is mandatory, of course.
    154 
    155 === From source
    156 If you want more control, you can download the source in archive form, or do a checkout from one of the official [[Trac:TracRepositories|source code repositories]].
    157 
    158 Be sure to have the prerequisites already installed. You can also obtain the Genshi and Babel source packages from http://www.edgewall.org and follow for them a similar installation procedure, or you can just `easy_install` those, see [#Usingeasy_install above].
    159 
    160 Once you've unpacked the Trac archive or performed the checkout, move in the top-level folder and do:
    161 {{{
    162 $ python ./setup.py install
    163 }}}
    164 
    165 You'll need root permissions or equivalent for this step.
    166 
    167 This will byte-compile the python source code and install it as an .egg file or folder in the `site-packages` directory
    168 of your Python installation. The .egg will also contain all other resources needed by standard Trac, such as htdocs and templates.
    169 
    170 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.
    171 
    172 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):
    173 {{{
    174 $ python ./setup.py install
    175 }}}
    176 Alternatively, you can do a `bdist_egg` and copy the .egg from dist/ to the place of your choice, or you can create a Windows installer (`bdist_wininst`).
    177 
    178 === Advanced Options ===
    179 
    180 ==== Custom location with `easy_install`
    181 
    182 To install Trac to a custom location, or find out about other advanced installation options, run:
    183 {{{
    184 easy_install --help
    185 }}}
    186 
    187 Also see [http://docs.python.org/inst/inst.html Installing Python Modules] for detailed information.
    188 
    189 Specifically, you might be interested in:
    190 {{{
    191 easy_install --prefix=/path/to/installdir
    192 }}}
    193 or, if installing Trac to a Mac OS X system:
    194 {{{
    195 easy_install --prefix=/usr/local --install-dir=/Library/Python/2.5/site-packages
    196 }}}
    197 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
    198 
    199 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.
    200 
    201 ==== Using `pip`
     142   Note that in this case you won't have the possibility to run a localized version of Trac;
     143   either use a released version or install from source
     144
     145{{{#!div style="border: 1pt dotted; margin: 1em"
     146**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].
     147}}}
     148
     149=== Using `pip`
    202150'pip' is an easy_install replacement that is very useful to quickly install python packages.
    203 To get a trac installation up and running in less than 5 minutes:
    204 
    205 Assuming you want to have your entire pip installation in /opt/user/trac:

    214 pip -E /opt/user/trac install trac mysql-python
    215 }}}
    216 
    217 Make sure your OS specific headers are available for pip to automatically build PostgreSQL (libpq-dev) or MySQL (libmysqlclient-dev) bindings.
    218 
    219 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 .
    220 
    221 All 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)
    222 
    223 Additionally, you can install several trac plugins (listed [http://pypi.python.org/pypi?:action=search&term=trac&submit=search here]) through pip.

     175=== From source
     176Of course, using the python-typical setup at the top of the source directory also works.
     177
     178You 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).

     219== Creating a Project Environment
    228220
    229221A [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.
    230222
    231223A new environment is created using [wiki:TracAdmin trac-admin]:
    232 {{{
     224{{{#!sh
    233225$ trac-admin /path/to/myproject initenv
    234226}}}
     
    239231For the other [DatabaseBackend database backends] you should plan ahead and already have a database ready to use at this point.
    240232
    241 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.
     233Since 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.
    242234
    243235Also note that the values you specify here can be changed later by directly editing the [TracIni conf/trac.ini] configuration file.
    244236
     237When 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).
     238
    245239Finally, 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:
    246 {{{
    247 # chown -R apache.apache /path/to/myproject
    248 }}}
     240{{{#!sh
     241$ chown -R apache.apache /path/to/myproject
     242}}}
     243
     244The 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).

    257 === Running the Standalone Server ===
     253=== Running the Standalone Server
    258254
    259255After having created a Trac environment, you can easily try the web interface by running the standalone server [wiki:TracStandalone tracd]:
    260 {{{
     256{{{#!sh
    261257$ tracd --port 8000 /path/to/myproject
    262258}}}
    263259
    264260Then, 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:
    265 {{{
     261{{{#!sh
    266262$ tracd -s --port 8000 /path/to/myproject
    267263}}}
    268264
    269 === Running Trac on a Web Server ===
     265{{{#!div style="border: 1pt dotted; margin: 1em"
     266**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. 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.
     267
     268To 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`.
     269{{{#!sh
     270export PKG_RESOURCES_CACHE_ZIP_MANIFESTS=1
     271}}}
     272
     273Alternatively, the variable can be set in the shell before executing `tracd`:
     274{{{#!sh
     275$ PKG_RESOURCES_CACHE_ZIP_MANIFESTS=1 tracd --port 8000 /path/to/myproject
     276}}}
     277}}}
     278
     279=== Running Trac on a Web Server
    270280
    271281Trac provides various options for connecting to a "real" web server:
     
    277287Trac 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.

    279 ==== Generating the Trac cgi-bin directory ==== #cgi-bin
     289==== Generating the Trac cgi-bin directory #cgi-bin
    280290
    281291In 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].
    282292
    283293There 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:
    284 {{{
     294{{{#!sh
    285295mkdir -p /usr/share/trac/projects/my-project
    286296trac-admin /usr/share/trac/projects/my-project initenv
     
    288298mv /tmp/deploy/* /usr/share/trac
    289299}}}
    290 
    291 
    292 ==== Mapping Static Resources ====
     300Don't forget to check that the web server has the execution right on scripts in the `/usr/share/trac/cgi-bin` directory.
     301
     302
     303==== Mapping Static Resources
    293304
    294305Out 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).
     
    306317 - `<plugins>/` - one directory for each resource directory managed by the plugins enabled for this environment
    307318
    308 ===== Example: Apache and `ScriptAlias` ===== #ScriptAlias-example
     319===== Example: Apache and `ScriptAlias` #ScriptAlias-example
    309320
    310321Assuming the deployment has been done this way:
    311 {{{
     322{{{#!sh
    312323$ trac-admin /var/trac/env deploy /path/to/trac/htdocs/common
    313324}}}
    314325
    315326Add 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:
    316 {{{
     327{{{#!apache
    317328Alias /trac/chrome/common /path/to/trac/htdocs/common
    318329Alias /trac/chrome/site /path/to/trac/htdocs/site
     
    325336
    326337If using mod_python, you might want to add this too (otherwise, the alias will be ignored):
    327 {{{
     338{{{#!apache
    328339<Location "/trac/chrome/common/">
    329340  SetHandler None
     
    334345
    335346Similarly, 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):
    336 {{{
     347{{{#!apache
    337348Alias /trac/chrome/site /path/to/projectenv/htdocs
    338349
     
    344355
    345356Alternatively 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:
    346 {{{
     357{{{#!ini
    347358[trac]
    348359htdocs_location = http://static.example.org/trac-common/
     
    351362
    352363Of 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:
    353 {{{
     364{{{#!sh
    354365$ ln -s /path/to/trac/htdocs/common /var/www/static.example.org/trac-common
    355366}}}
    356367
    357368
    358 ==== Setting up the Plugin Cache ====
    359 
    360 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.
    361 
    362 == Configuring Authentication ==
    363 
    364 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.

     395=== Enable version control components
     396
     397Support 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.
     398
     399The 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.
