    33Tracd is a lightweight standalone Trac web server.
    44It 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.
    55
    6 == Pros ==
    7 
    8  * Fewer dependencies: You don't need to install apache or any other web-server.
    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
    10  * 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).

     9 * Fast: Should be almost as fast as the [wiki:TracModWSGI mod_wsgi] version (and much faster than the [wiki:TracCgi CGI]), especially since the HTTP/1.1 version of the protocol is enabled by default.

     11
     12== Cons
    1313
    1414 * Fewer features: Tracd implements a very simple web-server and is not as configurable or as scalable as Apache httpd.
    15  * No native HTTPS support: [http://www.rickk.com/sslwrap/ sslwrap] can be used instead,
    16    or [http://trac.edgewall.org/wiki/STunnelTracd stunnel -- a tutorial on how to use stunnel with tracd] or Apache with mod_proxy.

     16== Usage examples
    1917
    2018A single project on port 8080. (http://localhost:8080/)
    21 {{{
     19{{{#!sh
    2220 $ tracd -p 8080 /path/to/project
    2321}}}
    24 Stricly speaking this will make your Trac accessible to everybody from your network rather than ''localhost only''. To truly limit it use ''--hostname'' option.

     22Strictly speaking this will make your Trac accessible to everybody from your network rather than ''localhost only''. To truly limit it use the `--hostname` option.
     23{{{#!sh
    2624 $ tracd --hostname=localhost -p 8080 /path/to/project
    2725}}}
    2826With more than one project. (http://localhost:8080/project1/ and http://localhost:8080/project2/)
    29 {{{
     27{{{#!sh
    3028 $ tracd -p 8080 /path/to/project1 /path/to/project2
    3129}}}
    3230
    33 You can't have the last portion of the path identical between the projects since Trac uses that name to keep the URLs of the
    34 different projects unique. So if you use `/project1/path/to` and `/project2/path/to`, you will only see the second project.

    3532
    3633An alternative way to serve multiple projects is to specify a parent directory in which each subdirectory is a Trac project, using the `-e` option. The example above could be rewritten:
    37 {{{
     34{{{#!sh
    3835 $ tracd -p 8080 -e /path/to
    3936}}}
    4037
    41 To exit the server on Windows, be sure to use {{{CTRL-BREAK}}} -- using {{{CTRL-C}}} will leave a Python process running in the background.
    42 
    43 == Installing as a Windows Service ==
    44 
    45 === Option 1 ===
    46 To install as a Windows service, get the [http://www.google.com/search?q=srvany.exe SRVANY] utility and run:
    47 {{{
     38There is support for the HTTPS protocol (//Since 1.3.4//). Specify the path to the PEM certificate file and keyfile using the `--certfile` and `--keyfile` options. You can specify just the `--certfile` option if you have a [https://docs.python.org/2/library/ssl.html#combined-key-and-certificate combined key and certificate].

    70 
    71 Note 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.)

    94 == Using Authentication ==
    95 
    96 Tracd allows you to run Trac without the need for Apache, but you can take advantage of Apache's password tools (htpasswd and htdigest) to easily create a password file in the proper format for tracd to use in authentication. (It is also possible to create the password file without htpasswd or htdigest; see below for alternatives)

     96
     97Tracd allows you to run Trac without the need for Apache, but you can take advantage of Apache's password tools (`htpasswd` and `htdigest`) to easily create a password file in the proper format for tracd to use in authentication. It is also possible to create the password file without `htpasswd` or `htdigest`; see below for alternatives.
     98
     99{{{#!div style="border: 1pt dotted; margin: 1em"
     100**Attention:** Make sure you place the generated password files on a filesystem which supports sub-second timestamps, as Trac will monitor their modified time and changes happening on a filesystem with too coarse-grained timestamp resolution (like `ext2` or `ext3` on Linux, or HFS+ on OSX).
     101}}}
    97102
    98103Tracd 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.
    99104
    100105The general format for using authentication is:
    101 {{{
     106{{{#!sh
    102107 $ tracd -p port --auth="base_project_dir,password_file_path,realm" project_path
    103108}}}
     
    115120Examples:
    116121
    117 {{{
     122{{{#!sh
    118123 $ tracd -p 8080 \
    119124   --auth="project1,/path/to/passwordfile,mycompany.com" /path/to/project1
     
    121126
    122127Of course, the password file can be be shared so that it is used for more than one project:
    123 {{{
     128{{{#!sh
    124129 $ tracd -p 8080 \
    125130   --auth="project1,/path/to/passwordfile,mycompany.com" \
     
    129134
    130135Another way to share the password file is to specify "*" for the project name:
    131 {{{
     136{{{#!sh
    132137 $ tracd -p 8080 \
    133138   --auth="*,/path/to/users.htdigest,mycompany.com" \
     
    135140}}}
    136141
    137 === Basic Authorization: Using a htpasswd password file ===
     142=== Basic Authorization: Using a htpasswd password file
     143
    138144This section describes how to use `tracd` with Apache .htpasswd files.
    139145
    140   Note: It is necessary (at least with Python 2.6) to install the fcrypt package in order to
    141   decode some htpasswd formats.  Trac source code attempt an `import crypt` first, but there
    142   is no such package for Python 2.6. Only `SHA-1` passwords (since Trac 1.0) work without this module.
     146'''Note''': On Windows It is necessary to install the [https://pypi.python.org/pypi/passlib passlib] package in order to decode some htpasswd formats. Only `SHA-1` passwords (since Trac 1.0) work without this module.
    143147
    144148To create a .htpasswd file use Apache's `htpasswd` command (see [#GeneratingPasswordsWithoutApache below] for a method to create these files without using Apache):
    145 {{{
     149{{{#!sh
    146150 $ sudo htpasswd -c /path/to/env/.htpasswd username
    147151}}}
    148152then for additional users:
    149 {{{
     153{{{#!sh
    150154 $ sudo htpasswd /path/to/env/.htpasswd username2
    151155}}}
    152156
    153157Then to start `tracd` run something like this:
    154 {{{
    155  $ tracd -p 8080 --basic-auth="projectdirname,/fullpath/environmentname/.htpasswd,realmname" /fullpath/environmentname
     158{{{#!sh
     159 $ tracd -p 8080 --basic-auth="project,/fullpath/environmentname/.htpasswd,realmname" /path/to/project
    156160}}}
    157161
    158162For example:
    159 {{{
    160  $ tracd -p 8080 --basic-auth="testenv,/srv/tracenv/testenv/.htpasswd,My Test Env" /srv/tracenv/testenv
    161 }}}
    162 ''Note:'' You might need to pass "-m" as a parameter to htpasswd on some platforms (OpenBSD).
    163 
    164 === Digest authentication: Using a htdigest password file ===
    165 
    166 If 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.
     163{{{#!sh
     164 $ tracd -p 8080 --basic-auth="project,/srv/tracenv/testenv/.htpasswd,My Test Env" /path/to/project
     165}}}
     166
     167'''Note:''' You might need to pass "-m" as a parameter to htpasswd on some platforms (OpenBSD).
     168
     169=== Digest authentication: Using a htdigest password file
     170
     171If you have Apache available, you can use the htdigest command to generate the password file. Type 'htdigest' to get some usage instructions, or read [https://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.
    167172
    168173Note that you can start tracd without the `--auth` argument, but if you click on the ''Login'' link you will get an error.
    169174
    170 === Generating Passwords Without Apache ===
    171 
    172 Basic Authorization can be accomplished via this [http://aspirine.org/htpasswd_en.html online HTTP Password generator] which also supports `SHA-1`.  Copy the generated password-hash line to the .htpasswd file on your system. Note that Windows Python lacks the "crypt" module that is the default hash type for htpasswd ; Windows Python can grok MD5 password hashes just fine and you should use MD5.
    173 
    174 You can use this simple Python script to generate a '''digest''' password file:
    175 
    176 {{{
    177 #!python
    178 from optparse import OptionParser
    179 # The md5 module is deprecated in Python 2.5
    180 try:
    181     from hashlib import md5
    182 except ImportError:
    183     from md5 import md5
    184 realm = 'trac'
    185 
    186 # build the options
    187 usage = "usage: %prog [options]"
    188 parser = OptionParser(usage=usage)
    189 parser.add_option("-u", "--username",action="store", dest="username", type = "string",
    190                   help="the username for whom to generate a password")
    191 parser.add_option("-p", "--password",action="store", dest="password", type = "string",
    192                   help="the password to use")
    193 parser.add_option("-r", "--realm",action="store", dest="realm", type = "string",
    194                   help="the realm in which to create the digest")
    195 (options, args) = parser.parse_args()
    196 
    197 # check options
    198 if (options.username is None) or (options.password is None):
    199    parser.error("You must supply both the username and password")
    200 if (options.realm is not None):
    201    realm = options.realm
    202    
    203 # Generate the string to enter into the htdigest file
    204 kd = lambda x: md5(':'.join(x)).hexdigest()
    205 print ':'.join((options.username, realm, kd([options.username, realm, options.password])))
    206 }}}
    207 
    208 Note: 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):
    209 
    210 {{{
    211  $ python trac-digest.py -u username -p password >> c:\digest.txt
    212  $ tracd --port 8000 --auth=proj_name,c:\digest.txt,trac c:\path\to\proj_name

     179Trac also provides `htpasswd` and `htdigest` scripts in [https://trac.edgewall.org/browser/trunk/contrib contrib] (also available in the tar or zip archive):

    261 == Tips ==
    262 
    263 === Serving static content ===
    264 
    265 If `tracd` is the only web server used for the project,
    266 it can also be used to distribute static content
    267 (tarballs, Doxygen documentation, etc.)
    268 
    269 This static content should be put in the `$TRAC_ENV/htdocs` folder,
    270 and is accessed by URLs like `<project_URL>/chrome/site/...`.
    271 
    272 Example: given a `$TRAC_ENV/htdocs/software-0.1.tar.gz` file,
    273 the corresponding relative URL would be `/<project_name>/chrome/site/software-0.1.tar.gz`,
    274 which 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).
    275

    278260=== Using tracd behind a proxy
     
    287269
    288270=== Authentication for tracd behind a proxy
    289 It is convenient to provide central external authentication to your tracd instances, instead of using {{{--basic-auth}}}. There is some discussion about this in #9206.
     271
     272It is convenient to provide central external authentication to your tracd instances, instead of using `--basic-auth`. See also [trac:#9206].
    290273
    291274Below is example configuration based on Apache 2.2, mod_proxy, mod_authnz_ldap.
     
    293276First we bring tracd into Apache's location namespace.

    296279<Location /project/proxified>
    297280        Require ldap-group cn=somegroup, ou=Groups,dc=domain.com
     
    304287
    305288Then we need a single file plugin to recognize HTTP_REMOTE_USER header as valid authentication source. HTTP headers like '''HTTP_FOO_BAR''' will get converted to '''Foo-Bar''' during processing. Name it something like '''remote-user-auth.py''' and drop it into '''proxified/plugins''' directory:
