    11= Tracd = 
    22 
    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 Using tracd with Apache .htpasswd files: 
    46  
    47 To create a .htpasswd file using htpasswd: 
    48  
    49 {{{ 
    50 sudo htpasswd -c /path/to/env/.htpasswd username 
     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.) 
     89 
     90 
     91The general format for using authentication is: 
     92{{{ 
     93 $ tracd -p port --auth="base_project_dir,password_file_path,realm" project_path 
     94}}} 
     95 
     96where: 
     97 
     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 
     106 
     107Examples: 
     108 
     109{{{ 
     110 $ tracd -p 8080 \ 
     111   --auth="project1,/path/to/passwordfile,mycompany.com" /path/to/project1 
     112}}} 
     113 
     114Of course, the password file can be be shared so that it is used for more than one project: 
     115{{{ 
     116 $ tracd -p 8080 \ 
     117   --auth="project1,/path/to/passwordfile,mycompany.com" \ 
     118   --auth="project2,/path/to/passwordfile,mycompany.com" \ 
     119   /path/to/project1 /path/to/project2 
     120}}} 
     121 
     122Another way to share the password file is to specify "*" for the project name: 
     123{{{ 
     124 $ tracd -p 8080 \ 
     125   --auth="*,/path/to/users.htdigest,mycompany.com" \ 
     126   /path/to/project1 /path/to/project2 
     127}}} 
     128 
     129=== Using a htpasswd password file === 
     130This section describes how to use `tracd` with Apache .htpasswd files. 
     131 
     132To create a .htpasswd file use Apache's `htpasswd` command (see [#GeneratingPasswordsWithoutApache below] for a method to create these files without using Apache): 
     133 
     134{{{ 
     135 $ sudo htpasswd -c /path/to/env/.htpasswd username 
    51136}}} 
    52137then for additional users: 
    53138{{{ 
    54 sudo htpasswd /var/www/html/.htpasswd-users username2 
    55 }}} 
    56 then for starting the tracd: 
    57 {{{ 
    58 tracd -p 8080 --basic-auth=environmentname,/fullpath/environmentname/.htpasswd,/fullpath/environmentname /fullpath/environmentname 
    59 }}} 
    60  
    61  
    62 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.) 
    63  
    64   ''Support for Basic authentication was added in version 0.9.'' 
    65  
    66 The general format for using authentication is: 
    67  
    68 {{{ 
    69  $ tracd -p port --auth=base_project_dir,password_file_path,realm project_path 
    70 }}} 
    71  
    72 where: 
    73  
    74  * '''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 
    75  * '''password_file_path''' path of the password file 
    76  * '''realm''' realm 
    77  * '''project_path''' path of the project 
    78  
    79 Example: 
    80  
    81 {{{ 
    82  $ tracd -p 8080 \ 
    83    --auth=project1,/path/to/users.htdigest,mycompany.com /path/to/project1 
    84 }}} 
    85 Of course, the digest file can be be shared so that it is used for more than one project: 
    86 {{{ 
    87  $ tracd -p 8080 \ 
    88    --auth=project1,/path/to/users.htdigest,mycompany.com \ 
    89    --auth=project2,/path/to/users.htdigest,mycompany.com \ 
    90    /path/to/project1 /path/to/project2 
    91 }}} 
    92  
    93 Another way to share the digest file is to specify "*" 
    94 for the project name: 
    95 {{{ 
    96  $ tracd -p 8080 \ 
    97    --auth=*,/path/to/users.htdigest,mycompany.com \ 
    98    /path/to/project1 /path/to/project2 
    99 }}} 
    100  
    101 == How to set up an htdigest password file == 
     139 $ sudo htpasswd /path/to/env/.htpasswd username2 
     140}}} 
     141 
     142Then to start `tracd` run something like this: 
     143 
     144{{{ 
     145 $ tracd -p 8080 --basic-auth="projectdirname,/fullpath/environmentname/.htpasswd,realmname" /fullpath/environmentname 
     146}}} 
     147 
     148For example: 
     149 
     150{{{ 
     151 $ tracd -p 8080 --basic-auth="testenv,/srv/tracenv/testenv/.htpasswd,My Test Env" /srv/tracenv/testenv 
     152}}} 
     153 
     154''Note:'' You might need to pass "-m" as a parameter to htpasswd on some platforms (OpenBSD). 
     155 
     156=== Using a htdigest password file === 
    102157 
    103158If 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. 
     
    105160Note that you can start tracd without the --auth argument, but if you click on the ''Login'' link you will get an error. 
    106161 
    107 == Generating Passwords Without Apache == 
     162=== Generating Passwords Without Apache === 
    108163 
    109164If you don't have Apache available, you can use this simple Python script to generate your passwords: 
     
    112167#!python 
    113168from optparse import OptionParser 
    114 import md5 
     169# The md5 module is deprecated in Python 2.5 
     170try: 
     171    from hashlib import md5 
     172except ImportError: 
     173    from md5 import md5 
     174realm = 'trac' 
    115175 
    116176# build the options 
     
    121181parser.add_option("-p", "--password",action="store", dest="password", type = "string", 
    122182                  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") 
    123185(options, args) = parser.parse_args() 
    124186 
     
    126188if (options.username is None) or (options.password is None): 
    127189   parser.error("You must supply both the username and password") 
     190if (options.realm is not None): 
     191   realm = options.realm 
    128192    
    129193# Generate the string to enter into the htdigest file 
    130 realm = 'trac' 
    131 kd = lambda x: md5.md5(':'.join(x)).hexdigest() 
     194kd = lambda x: md5(':'.join(x)).hexdigest() 
    132195print ':'.join((options.username, realm, kd([options.username, realm, options.password]))) 
    133196}}} 
     
    136199 
    137200{{{ 
    138 python trac-digest.py -u username -p password >> c:\digest.txt 
    139 tracd --port 8000 --auth=proj_name,c:\digest.txt,trac c:\path\to\proj_name 
    140 }}} 
    141  
    142 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).  If you do not have Apache, [trac:source:/tags/trac-0.11b2/contrib/htpasswd.py htpasswd.py] may help.  (Note that it requires a `crypt` or `fcrypt` module; see the source comments for details.) 
     201 $ python trac-digest.py -u username -p password >> c:\digest.txt 
     202 $ tracd --port 8000 --auth=proj_name,c:\digest.txt,trac c:\path\to\proj_name 
     203}}}

    143207 
    144208It is possible to use md5sum utility to generate digest-password file using such method: 
    145209{{{ 
    146 echo -e "${user}:trac:${password}\c" | md5sum - >>to-file 
    147 }}} 
    148 and manually delete " -" from the end and add "${user}:trac:" to the start of line from 'to-file'. You can see attachment:trac-digest-corrected.sh for detail. 
     210 $ printf "${user}:trac:${password}" | md5sum - >>user.htdigest 
     211}}} 
     212and manually delete " -" from the end and add "${user}:trac:" to the start of line from 'to-file'.

    150242== Tips == 
     
    152244=== Serving static content === 
    153245 
    154 If `tracd` is the only webserver used for the project,  
     246If `tracd` is the only web server used for the project,  
    155247it can also be used to distribute static content  
    156248(tarballs, Doxygen documentation, etc.) 
     
    161253Example: given a `$TRAC_ENV/htdocs/software-0.1.tar.gz` file, 
    162254the corresponding relative URL would be `/<project_name>/chrome/site/software-0.1.tar.gz`,  
    163 which in turn can be written using the relative link syntax 
    164 in the Wiki: `[/<project_name>/chrome/site/software-0.1.tar.gz]`  
    165  
    166 The development version of Trac supports a new `htdocs:` TracLinks  
    167 syntax for the above. With this, the example link above can be written simply  
    168 `htdocs:software-0.1.tar.gz`.  
    169  
    170 === Using apache rewrite rules === 
    171 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. 
     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).  
     256 
     257 ''Support for `htdocs:` TracLinks syntax was added in version 0.10'' 
     258 
     259=== Using tracd behind a proxy 
     260 
     261In some situations when you choose to use tracd behind Apache or another web server. 
     262 
     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. 
     264 
     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. 
     266 
     267See also [trac:TracOnWindowsIisAjp], [trac:TracNginxRecipe]. 
    172268 
    173269=== Serving a different base path than / === 
    174 Tracd supports serving projects with different base urls then /<project>. The parameter name to change this is 
    175 {{{ 
    176 tracd --base-path=/some/path 
     270Tracd supports serving projects with different base urls than /<project>. The parameter name to change this is
