    v2 v3  
    11= Tracd =
    3 Tracd is a lightweight standalone Trac web server. In most cases it's easier to setup and runs faster than the [wiki:TracCgi CGI script].
     3Tracd is a lightweight standalone Trac web server.
     4It can be used in a variety of situations, from a test or development server to a multiprocess setup behind another web server used as a load balancer.
    56== Pros ==
    78 * Fewer dependencies: You don't need to install apache or any other web-server.
    8  * Fast: Should be almost as fast as the [wiki:TracModPython mod_python] version (and much faster than the [wiki:TracCgi CGI]).
     9 * Fast: Should be almost as fast as the [wiki:TracModPython mod_python] version (and much faster than the [wiki:TracCgi CGI]), even more so since version 0.12 where the HTTP/1.1 version of the protocol is enabled by default
    910 * Automatic reloading: For development, Tracd can be used in ''auto_reload'' mode, which will automatically restart the server whenever you make a change to the code (in Trac itself or in a plugin).
    1112== Cons ==
    13  * Fewer features: Tracd implements a very simple web-server and is not as configurable or as scalable as Apache HTTPD.
     14 * Fewer features: Tracd implements a very simple web-server and is not as configurable or as scalable as Apache httpd.
    1415 * No native HTTPS support: [ sslwrap] can be used instead,
    1516   or [ stunnel -- a tutorial on how to use stunnel with tracd] or Apache with mod_proxy.
    2122 $ tracd -p 8080 /path/to/project
     24Stricly speaking this will make your Trac accessible to everybody from your network rather than ''localhost only''. To truly limit it use ''--hostname'' option.
     26 $ tracd --hostname=localhost -p 8080 /path/to/project
    2328With more than one project. (http://localhost:8080/project1/ and http://localhost:8080/project2/)
     41To exit the server on Windows, be sure to use {{{CTRL-BREAK}}} -- using {{{CTRL-C}}} will leave a Python process running in the background.
     43== Installing as a Windows Service ==
     45=== Option 1 ===
     46To install as a Windows service, get the [ SRVANY] utility and run:
     48 C:\path\to\instsrv.exe tracd C:\path\to\srvany.exe
     49 reg add HKLM\SYSTEM\CurrentControlSet\Services\tracd\Parameters /v Application /d "\"C:\path\to\python.exe\" \"C:\path\to\python\scripts\\" <your tracd parameters>"
     50 net start tracd
     53'''DO NOT''' use {{{tracd.exe}}}.  Instead register {{{python.exe}}} directly with {{{}}} as a parameter.  If you use {{{tracd.exe}}}, it will spawn the python process without SRVANY's knowledge.  This python process will survive a {{{net stop tracd}}}.
     55If you want tracd to start automatically when you boot Windows, do:
     57 sc config tracd start= auto
     60The spacing here is important.
     63Once the service is installed, it might be simpler to run the Registry Editor rather than use the `reg add` command documented above.  Navigate to:[[BR]]
     66Three (string) parameters are provided:
     67||!AppDirectory ||C:\Python26\ ||
     68||Application ||python.exe ||
     69||!AppParameters ||scripts\ -p 8080 ... ||
     71Note that, if the !AppDirectory is set as above, the paths of the executable ''and'' of the script name and parameter values are relative to the directory.  This makes updating Python a little simpler because the change can be limited, here, to a single point.
     72(This is true for the path to the .htpasswd file, as well, despite the documentation calling out the /full/path/to/htpasswd; however, you may not wish to store that file under the Python directory.)
     75For Windows 7 User, srvany.exe may not be an option, so you can use [ WINSERV] utility and run:
     77"C:\path\to\winserv.exe" install tracd -displayname "tracd" -start auto "C:\path\to\python.exe" c:\path\to\python\scripts\ <your tracd parameters>"
     79net start tracd
     82=== Option 2 ===
     84Use [ WindowsServiceScript], available at [ Trac Hacks]. Installs, removes, starts, stops, etc. your Trac service.
    3686== Using Authentication ==
    38 Tracd provides support for both Basic and Digest authentication. The default is to use Digest; to use Basic authentication, replace `--auth` with `--basic-auth` in the examples below, and omit the realm.
    40   ''Support for Basic authentication was added in version 0.9.''
    42 If the file `/path/to/users.htdigest` contains user accounts for project1 with the realm "", you'd use the following command-line to start tracd:
    43 {{{
    44  $ tracd -p 8080 --auth project1,/path/to/users.htdigest, /path/to/project1
    45 }}}
    47 '''Note''': the project "name" passed to the `--auth` option is the base name of the project environment directory.
    49 Of course, the digest file can be be shared so that it is used for more than one project:
     88Tracd provides support for both Basic and Digest authentication. The default is to use Digest; to use Basic authentication, replace `--auth` with `--basic-auth` in the examples below. (You must still specify a dialogic "realm", which can be an empty string by trailing the BASICAUTH with a comma.)
     91The general format for using authentication is:
     93 $ tracd -p port --auth="base_project_dir,password_file_path,realm" project_path
     98 * '''base_project_dir''': the base directory of the project specified as follows:
     99   * when serving multiple projects: ''relative'' to the `project_path`
     100   * when serving only a single project (`-s`): the name of the project directory
     101 Don't use an absolute path here as this won't work. ''Note:'' This parameter is case-sensitive even for environments on Windows.
     102 * '''password_file_path''': path to the password file
     103 * '''realm''': the realm name (can be anything)
     104 * '''project_path''': path of the project
     105 * **`--auth`** in the above means use Digest authentication, replace `--auth` with `--basic-auth` if you want to use Basic auth
    51110 $ tracd -p 8080 \
    52    --auth project1,/path/to/users.htdigest, \
    53    --auth project2,/path/to/users.htdigest, \
     111   --auth="project1,/path/to/passwordfile," /path/to/project1
     114Of course, the password file can be be shared so that it is used for more than one project:
     116 $ tracd -p 8080 \
     117   --auth="project1,/path/to/passwordfile," \
     118   --auth="project2,/path/to/passwordfile," \
    54119   /path/to/project1 /path/to/project2
    57 Another way to share the digest file is to specify "*"
    58 for the project name:
     122Another way to share the password file is to specify "*" for the project name:
    60124 $ tracd -p 8080 \
    61    --auth *,/path/to/users.htdigest, \
     125   --auth="*,/path/to/users.htdigest," \
    62126   /path/to/project1 /path/to/project2
    65 == How to set up an htdigest password file ==
     129=== Using a htpasswd password file ===
     130This section describes how to use `tracd` with Apache .htpasswd files.
     132To create a .htpasswd file use Apache's `htpasswd` command (see [#GeneratingPasswordsWithoutApache below] for a method to create these files without using Apache):
     135 $ sudo htpasswd -c /path/to/env/.htpasswd username
     137then for additional users:
     139 $ sudo htpasswd /path/to/env/.htpasswd username2
     142Then to start `tracd` run something like this:
     145 $ tracd -p 8080 --basic-auth="projectdirname,/fullpath/environmentname/.htpasswd,realmname" /fullpath/environmentname
     148For example:
     151 $ tracd -p 8080 --basic-auth="testenv,/srv/tracenv/testenv/.htpasswd,My Test Env" /srv/tracenv/testenv
     154''Note:'' You might need to pass "-m" as a parameter to htpasswd on some platforms (OpenBSD).
     156=== Using a htdigest password file ===
    67158If you have Apache available, you can use the htdigest command to generate the password file. Type 'htdigest' to get some usage instructions, or read [ this page] from the Apache manual to get precise instructions.  You'll be prompted for a password to enter for each user that you create.  For the name of the password file, you can use whatever you like, but if you use something like `users.htdigest` it will remind you what the file contains. As a suggestion, put it in your <projectname>/conf folder along with the [TracIni trac.ini] file.
    69160Note that you can start tracd without the --auth argument, but if you click on the ''Login'' link you will get an error.
    71 == Generating Passwords Without Apache ==
     162=== Generating Passwords Without Apache ===
    73164If you don't have Apache available, you can use this simple Python script to generate your passwords:
    76168from optparse import OptionParser
    77 import md5
     169# The md5 module is deprecated in Python 2.5
     171    from hashlib import md5
     172except ImportError:
     173    from md5 import md5
     174realm = 'trac'
    79176# build the options
    84181parser.add_option("-p", "--password",action="store", dest="password", type = "string",
    85182                  help="the password to use")
     183parser.add_option("-r", "--realm",action="store", dest="realm", type = "string",
     184                  help="the realm in which to create the digest")
    86185(options, args) = parser.parse_args()
    89188if (options.username is None) or (options.password is None):
    90189   parser.error("You must supply both the username and password")
     190if (options.realm is not None):
     191   realm = options.realm
    92193# Generate the string to enter into the htdigest file
    93 realm = 'trac'
    94 kd = lambda x: md5.md5(':'.join(x)).hexdigest()
     194kd = lambda x: md5(':'.join(x)).hexdigest()
    95195print ':'.join((options.username, realm, kd([options.username, realm, options.password])))
    101 python -u username -p password >> c:\digest.txt
    102 python tracd --port 8000 --auth proj_name,c:\digest.txt,trac c:\path\to\proj_name
     201 $ python -u username -p password >> c:\digest.txt
     202 $ tracd --port 8000 --auth=proj_name,c:\digest.txt,trac c:\path\to\proj_name
     206Note: If you would like to use --basic-auth you need to use htpasswd tool from apache server to generate .htpasswd file. The remaining part is similar but make sure to use empty realm (i.e. coma after path). Make sure to use -m option for it.  If you do not have Apache, [trac:source:/tags/trac-0.11/contrib/] may help.  (Note that it requires a `crypt` or `fcrypt` module; see the source comments for details.)
     208It is possible to use md5sum utility to generate digest-password file using such method:
     210 $ printf "${user}:trac:${password}" | md5sum - >>user.htdigest
     212and manually delete " -" from the end and add "${user}:trac:" to the start of line from 'to-file'.
     214== Reference ==
     216Here's the online help, as a reminder (`tracd --help`):

    107244=== Serving static content ===
    109 If `tracd` is the only webserver used for the project,
     246If `tracd` is the only web server used for the project,
    110247it can also be used to distribute static content
    111248(tarballs, Doxygen documentation, etc.)
    116253Example: given a `$TRAC_ENV/htdocs/software-0.1.tar.gz` file,
    117254the corresponding relative URL would be `/<project_name>/chrome/site/software-0.1.tar.gz`,
    118 which in turn can be written using the relative link syntax
    119 in the Wiki: `[/<project_name>/chrome/site/software-0.1.tar.gz]`
    121 The development version of Trac supports a new `htdocs:` TracLinks
    122 syntax for the above. With this, the example link above can be written simply
    123 `htdocs:software-0.1.tar.gz`.
     255which in turn can be written as `htdocs:software-0.1.tar.gz` (TracLinks syntax) or `[/<project_name>/chrome/site/software-0.1.tar.gz]` (relative link syntax).
     257 ''Support for `htdocs:` TracLinks syntax was added in version 0.10''
     259=== Using tracd behind a proxy
     261In some situations when you choose to use tracd behind Apache or another web server.
     263In this situation, you might experience issues with redirects, like being redirected to URLs with the wrong host or protocol. In this case (and only in this case), setting the `[trac] use_base_url_for_redirect` to `true` can help, as this will force Trac to use the value of `[trac] base_url` for doing the redirects.
     265If you're using the AJP protocol to connect with `tracd` (which is possible if you have flup installed), then you might experience problems with double quoting. Consider adding the `--unquote` parameter.
     267See also [trac:TracOnWindowsIisAjp], [trac:TracNginxRecipe].
     269=== Serving a different base path than / ===
     270Tracd supports serving projects with different base urls than /<project>. The parameter name to change this is
     272 $ tracd --base-path=/some/path
