    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.
    45
    56== Pros ==
    67
    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).
    1011
    1112== Cons ==
    1213
    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: [http://www.rickk.com/sslwrap/ sslwrap] can be used instead,
    1516   or [http://trac.edgewall.org/wiki/STunnelTracd stunnel -- a tutorial on how to use stunnel with tracd] or Apache with mod_proxy.
     
    4041To exit the server on Windows, be sure to use {{{CTRL-BREAK}}} -- using {{{CTRL-C}}} will leave a Python process running in the background.
    4142
     43== Installing as a Windows Service ==
     44
     45=== Option 1 ===
     46To install as a Windows service, get the [http://www.google.com/search?q=srvany.exe SRVANY] utility and run:
     47{{{
     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\tracd-script.py\" <your tracd parameters>"
     50 net start tracd
     51}}}
     52
     53'''DO NOT''' use {{{tracd.exe}}}.  Instead register {{{python.exe}}} directly with {{{tracd-script.py}}} 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}}}.
     54
     55If you want tracd to start automatically when you boot Windows, do:
     56{{{
     57 sc config tracd start= auto
     58}}}
     59
     60The spacing here is important.
     61
     62{{{#!div
     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]]
     64`HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\tracd\Parameters`
     65
     66Three (string) parameters are provided:
     67||!AppDirectory ||C:\Python26\ ||
     68||Application ||python.exe ||
     69||!AppParameters ||scripts\tracd-script.py -p 8080 ... ||
     70
     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.)
     73}}}
     74
     75For Windows 7 User, srvany.exe may not be an option, so you can use [http://www.google.com/search?q=winserv.exe WINSERV] utility and run:
     76{{{
     77"C:\path\to\winserv.exe" install tracd -displayname "tracd" -start auto "C:\path\to\python.exe" c:\path\to\python\scripts\tracd-script.py <your tracd parameters>"
     78
     79net start tracd
     80}}}
     81
     82=== Option 2 ===
     83
     84Use [http://trac-hacks.org/wiki/WindowsServiceScript WindowsServiceScript], available at [http://trac-hacks.org/ Trac Hacks]. Installs, removes, starts, stops, etc. your Trac service.
    4285
    4386== Using Authentication ==
    4487
    45 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. (You must still specify a dialogic "realm", which can be an empty string by trailing the BASICAUTH with a comma.)
    46 
    47   ''Support for Basic authentication was added in version 0.9.''
     88Tracd provides support for both Basic and Digest authentication. Digest is considered more secure. The examples below use Digest; to use Basic authentication, replace `--auth` with `--basic-auth` in the command line.
    4889
    4990The general format for using authentication is:
    50 
    51 {{{
    52  $ tracd -p port --auth=base_project_dir,password_file_path,realm project_path
    53 }}}
    54 
     91{{{
     92 $ tracd -p port --auth="base_project_dir,password_file_path,realm" project_path
     93}}}
    5594where:
    56 
    57  * '''base_project_dir''' is the base directory of the project; note: this doesn't refer to the project name, and it is case-sensitive even for windows environments
    58  * '''password_file_path''' path of the password file
    59  * '''realm''' realm
    60  * '''project_path''' path of the project
    61 
    62 Example:
     95 * '''base_project_dir''': the base directory of the project specified as follows:
     96   * when serving multiple projects: ''relative'' to the `project_path`
     97   * when serving only a single project (`-s`): the name of the project directory
     98 Don't use an absolute path here as this won't work. ''Note:'' This parameter is case-sensitive even for environments on Windows.
     99 * '''password_file_path''': path to the password file
     100 * '''realm''': the realm name (can be anything)
     101 * '''project_path''': path of the project
     102
     103 * **`--auth`** in the above means use Digest authentication, replace `--auth` with `--basic-auth` if you want to use Basic auth.  Although Basic authentication does not require a "realm", the command parser does, so the second comma is required, followed directly by the closing quote for an empty realm name.
     104
     105Examples:
    63106
    64107{{{
    65108 $ tracd -p 8080 \
    66    --auth=project1,/path/to/users.htdigest,mycompany.com /path/to/project1
    67 }}}
    68 Of course, the digest file can be be shared so that it is used for more than one project:
     109   --auth="project1,/path/to/passwordfile,mycompany.com" /path/to/project1
     110}}}
     111
     112Of course, the password file can be be shared so that it is used for more than one project:
    69113{{{
    70114 $ tracd -p 8080 \
    71    --auth=project1,/path/to/users.htdigest,mycompany.com \
    72    --auth=project2,/path/to/users.htdigest,mycompany.com \
     115   --auth="project1,/path/to/passwordfile,mycompany.com" \
     116   --auth="project2,/path/to/passwordfile,mycompany.com" \
    73117   /path/to/project1 /path/to/project2
    74118}}}
    75119
    76 Another way to share the digest file is to specify "*"
    77 for the project name:
     120Another way to share the password file is to specify "*" for the project name:
    78121{{{
    79122 $ tracd -p 8080 \
    80    --auth=*,/path/to/users.htdigest,mycompany.com \
     123   --auth="*,/path/to/users.htdigest,mycompany.com" \
    81124   /path/to/project1 /path/to/project2
    82125}}}
    83126
    84 == How to set up an htdigest password file ==
     127=== Basic Authorization: Using a htpasswd password file ===
     128This section describes how to use `tracd` with Apache .htpasswd files.
     129
     130To create a .htpasswd file use Apache's `htpasswd` command (see [#GeneratingPasswordsWithoutApache below] for a method to create these files without using Apache):
     131{{{
     132 $ sudo htpasswd -c /path/to/env/.htpasswd username
     133}}}
     134then for additional users:
     135{{{
     136 $ sudo htpasswd /path/to/env/.htpasswd username2
     137}}}
     138
     139Then to start `tracd` run something like this:
     140{{{
     141 $ tracd -p 8080 --basic-auth="projectdirname,/fullpath/environmentname/.htpasswd,realmname" /fullpath/environmentname
     142}}}
     143
     144For example:
     145{{{
     146 $ tracd -p 8080 --basic-auth="testenv,/srv/tracenv/testenv/.htpasswd,My Test Env" /srv/tracenv/testenv
     147}}}
     148''Note:'' You might need to pass "-m" as a parameter to htpasswd on some platforms (OpenBSD).
     149
     150=== Digest authentication: Using a htdigest password file ===
    85151
    86152If you have Apache available, you can use the htdigest command to generate the password file. Type 'htdigest' to get some usage instructions, or read [http://httpd.apache.org/docs/2.0/programs/htdigest.html 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.
     
    88154Note that you can start tracd without the --auth argument, but if you click on the ''Login'' link you will get an error.
    89155
    90 == Generating Passwords Without Apache ==
    91 
    92 If you don't have Apache available, you can use this simple Python script to generate your passwords:
     156=== Generating Passwords Without Apache ===
     157
     158Basic Authorization can be accomplished via this [http://www.4webhelp.net/us/password.php online HTTP Password generator].  Copy the generated password-hash line to the .htpasswd file on your system.
     159
     160You can use this simple Python script to generate a '''digest''' password file:
    93161
    94162{{{
    95163#!python
    96164from optparse import OptionParser
    97 import md5
     165# The md5 module is deprecated in Python 2.5
     166try:
     167    from hashlib import md5
     168except ImportError:
     169    from md5 import md5
     170realm = 'trac'
    98171
    99172# build the options
     
    104177parser.add_option("-p", "--password",action="store", dest="password", type = "string",
    105178                  help="the password to use")
     179parser.add_option("-r", "--realm",action="store", dest="realm", type = "string",
     180                  help="the realm in which to create the digest")
    106181(options, args) = parser.parse_args()
    107182
     
    109184if (options.username is None) or (options.password is None):
    110185   parser.error("You must supply both the username and password")
     186if (options.realm is not None):
     187   realm = options.realm
    111188   
    112189# Generate the string to enter into the htdigest file
    113 realm = 'trac'
    114 kd = lambda x: md5.md5(':'.join(x)).hexdigest()
     190kd = lambda x: md5(':'.join(x)).hexdigest()
    115191print ':'.join((options.username, realm, kd([options.username, realm, options.password])))
    116192}}}
    117193
    118 Note: If you use the above script you must use the --auth option to tracd, not --basic-auth, and you must set the realm in the --auth value to 'trac' (without the quotes). Example usage (assuming you saved the script as trac-digest.py):
    119 
    120 {{{
    121 python trac-digest.py -u username -p password >> c:\digest.txt
    122 tracd --port 8000 --auth=proj_name,c:\digest.txt,trac c:\path\to\proj_name
    123 }}}
    124 
    125 Note: 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). When using on Windows make sure to use -m option for it (did not tested it on *nix, so not sure if that is the case there).
     194Note: If you use the above script you must set the realm in the `--auth` argument to '''`trac`'''. Example usage (assuming you saved the script as trac-digest.py):
     195
     196{{{
     197 $ python trac-digest.py -u username -p password >> c:\digest.txt
     198 $ tracd --port 8000 --auth=proj_name,c:\digest.txt,trac c:\path\to\proj_name
     199}}}
     200
     201==== Using `md5sum`
     202It is possible to use `md5sum` utility to generate digest-password file:
     203{{{
     204 $ printf "${user}:trac:${password}" | md5sum - >>user.htdigest
     205}}}
     206and manually delete " -" from the end and add "${user}:trac:" to the start of line from 'to-file'.

    126235
    127236== Tips ==
     
    129238=== Serving static content ===
    130239
    131 If `tracd` is the only webserver used for the project,
     240If `tracd` is the only web server used for the project,
    132241it can also be used to distribute static content
    133242(tarballs, Doxygen documentation, etc.)
     
    138247Example: given a `$TRAC_ENV/htdocs/software-0.1.tar.gz` file,
    139248the corresponding relative URL would be `/<project_name>/chrome/site/software-0.1.tar.gz`,
    140 which in turn can be written using the relative link syntax
    141 in the Wiki: `[/<project_name>/chrome/site/software-0.1.tar.gz]`
    142 
    143 The development version of Trac supports a new `htdocs:` TracLinks
    144 syntax for the above. With this, the example link above can be written simply
    145 `htdocs:software-0.1.tar.gz`.
    146 
    147 === Using apache rewrite rules ===
    148 In some situations when you choose to use tracd behind apache, 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.
     249which 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).
     250
     251 ''Support for `htdocs:` TracLinks syntax was added in version 0.10''
     252
     253=== Using tracd behind a proxy
     254
     255In some situations when you choose to use tracd behind Apache or another web server.
     256
     257In 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.
     258
     259If 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.

    149262
    150263=== Serving a different base path than / ===
    151 Tracd supports serving projects with different base urls then /<project>. The parameter name to change this is
    152 {{{
    153 tracd --base-path=/some/path
     264Tracd supports serving projects with different base urls than /<project>. The parameter name to change this is
