    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).
    10   * Options for tracd: `-r, --auto-reload`
    1111
    1212== Cons ==
    1313
    14  * 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.
    1515 * No native HTTPS support: [http://www.rickk.com/sslwrap/ sslwrap] can be used instead,
    1616   or [http://trac.edgewall.org/wiki/STunnelTracd stunnel -- a tutorial on how to use stunnel with tracd] or Apache with mod_proxy.
     
    4343== Installing as a Windows Service ==
    4444
     45=== Option 1 ===
    4546To install as a Windows service, get the [http://www.google.com/search?q=srvany.exe SRVANY] utility and run:
    4647{{{
     
    5960The spacing here is important.
    6061
     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.
     85
    6186== Using Authentication ==
    6287
    63 Using tracd with Apache .htpasswd files:
    64 
    65 To create a .htpasswd file using htpasswd:
    66 
     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.
     89
     90The general format for using authentication is:
     91{{{
     92 $ tracd -p port --auth="base_project_dir,password_file_path,realm" project_path
     93}}}
     94where:
     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:
     106
     107{{{
     108 $ tracd -p 8080 \
     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:
     113{{{
     114 $ tracd -p 8080 \
     115   --auth="project1,/path/to/passwordfile,mycompany.com" \
     116   --auth="project2,/path/to/passwordfile,mycompany.com" \
     117   /path/to/project1 /path/to/project2
     118}}}
     119
     120Another way to share the password file is to specify "*" for the project name:
     121{{{
     122 $ tracd -p 8080 \
     123   --auth="*,/path/to/users.htdigest,mycompany.com" \
     124   /path/to/project1 /path/to/project2
     125}}}
     126
     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):
    67131{{{
    68132 $ sudo htpasswd -c /path/to/env/.htpasswd username
     
    72136 $ sudo htpasswd /path/to/env/.htpasswd username2
    73137}}}
    74 then for starting the tracd (on windows skip the "=" after --basic-auth):
    75 {{{
    76  $ tracd -p 8080 --basic-auth=environmentname,/fullpath/environmentname/.htpasswd,/fullpath/environmentname /fullpath/environmentname
    77 }}}
    78 
    79 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.)
    80 
    81   ''Support for Basic authentication was added in version 0.9.''
    82 
    83 The general format for using authentication is (on windows skip the "=" after --auth):
    84 
    85 {{{
    86  $ tracd -p port --auth=base_project_dir,password_file_path,realm project_path
    87 }}}
    88 
    89 where:
    90 
    91  * '''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
    92  * '''password_file_path''' path of the password file
    93  * '''realm''' realm
    94  * '''project_path''' path of the project
    95 
    96 Example (on windows skip the "=" after --auth):
    97 
    98 {{{
    99  $ tracd -p 8080 \
    100    --auth=project1,/path/to/users.htdigest,mycompany.com /path/to/project1
    101 }}}
    102 Of course, the digest file can be be shared so that it is used for more than one project:
    103 {{{
    104  $ tracd -p 8080 \
    105    --auth=project1,/path/to/users.htdigest,mycompany.com \
    106    --auth=project2,/path/to/users.htdigest,mycompany.com \
    107    /path/to/project1 /path/to/project2
    108 }}}
    109 
    110 Another way to share the digest file is to specify "*"
    111 for the project name:
    112 {{{
    113  $ tracd -p 8080 \
    114    --auth="*",/path/to/users.htdigest,mycompany.com \
    115    /path/to/project1 /path/to/project2
    116 }}}
    117 If using the `-s` parameter for serving a Trac environment from the root of a domain, one must use `*` for the project name
    118 
    119 == How to set up an htdigest password file ==
     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 ===
    120151
    121152If 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.
     
    123154Note that you can start tracd without the --auth argument, but if you click on the ''Login'' link you will get an error.
    124155
    125 == Generating Passwords Without Apache ==
    126 
    127 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:
    128161
    129162{{{
     
    159192}}}
    160193
    161 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):
     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):
    162195
    163196{{{
     
    166199}}}
    167200
    168 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.)
    169 
    170 It is possible to use md5sum utility to generate digest-password file using such method:
     201==== Using `md5sum`
     202It is possible to use `md5sum` utility to generate digest-password file:
    171203{{{
    172204 $ printf "${user}:trac:${password}" | md5sum - >>user.htdigest
     
    174206and manually delete " -" from the end and add "${user}:trac:" to the start of line from 'to-file'.
    175207

     209
     210Here's the online help, as a reminder (`tracd --help`):

    176236== Tips ==
    177237
    178238=== Serving static content ===
    179239
    180 If `tracd` is the only webserver used for the project,
     240If `tracd` is the only web server used for the project,
    181241it can also be used to distribute static content
    182242(tarballs, Doxygen documentation, etc.)
     
    187247Example: given a `$TRAC_ENV/htdocs/software-0.1.tar.gz` file,
    188248the corresponding relative URL would be `/<project_name>/chrome/site/software-0.1.tar.gz`,
    189 which in turn can be written using the relative link syntax
    190 in the Wiki: `[/<project_name>/chrome/site/software-0.1.tar.gz]`
    191 
    192 Since 0.10, Trac supports a new `htdocs:` TracLinks
    193 syntax for the above. With this, the example link above can be written simply
    194 `htdocs:software-0.1.tar.gz`.
    195 
    196 === Using apache rewrite rules ===
    197 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.
