    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 ==
     6== Pros
    77
    88 * Fewer dependencies: You don't need to install apache or any other web-server.
     
    1010 * 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).
    1111
    12 == Cons ==
     12== Cons
    1313
    1414 * Fewer features: Tracd implements a very simple web-server and is not as configurable or as scalable as Apache httpd.

    3535
    3636An 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 {{{
     37{{{#!sh
    3838 $ tracd -p 8080 -e /path/to

    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)
    97 
    98 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) may go undetected.

     98**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).
     99}}}
    99100
    100101Tracd 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.
    101102
    102103The general format for using authentication is:
    103 {{{
     104{{{#!sh
    104105 $ tracd -p port --auth="base_project_dir,password_file_path,realm" project_path
    105106}}}
     
    117118Examples:
    118119
    119 {{{
     120{{{#!sh
    120121 $ tracd -p 8080 \
    121122   --auth="project1,/path/to/passwordfile,mycompany.com" /path/to/project1
     
    123124
    124125Of course, the password file can be be shared so that it is used for more than one project:
    125 {{{
     126{{{#!sh
    126127 $ tracd -p 8080 \
    127128   --auth="project1,/path/to/passwordfile,mycompany.com" \
     
    131132
    132133Another way to share the password file is to specify "*" for the project name:
    133 {{{
     134{{{#!sh
    134135 $ tracd -p 8080 \
    135136   --auth="*,/path/to/users.htdigest,mycompany.com" \
     
    137138}}}
    138139
    139 === Basic Authorization: Using a htpasswd password file ===
     140=== Basic Authorization: Using a htpasswd password file
    140141This section describes how to use `tracd` with Apache .htpasswd files.
    141142
    142   Note: It is necessary (at least with Python 2.6) to install the fcrypt package in order to
    143   decode some htpasswd formats.  Trac source code attempt an `import crypt` first, but there
    144   is no such package for Python 2.6. Only `SHA-1` passwords (since Trac 1.0) work without this module.
     143  Note: On Windows It is necessary to install the [https://pypi.python.org/pypi/passlib passlib]
     144  package in order to decode some htpasswd formats. Only `SHA-1` passwords (since Trac 1.0)
     145  work without this module.
    145146
    146147To create a .htpasswd file use Apache's `htpasswd` command (see [#GeneratingPasswordsWithoutApache below] for a method to create these files without using Apache):
    147 {{{
     148{{{#!sh
    148149 $ sudo htpasswd -c /path/to/env/.htpasswd username
    149150}}}
    150151then for additional users:
    151 {{{
     152{{{#!sh
    152153 $ sudo htpasswd /path/to/env/.htpasswd username2
    153154}}}
    154155
    155156Then to start `tracd` run something like this:
    156 {{{
    157  $ tracd -p 8080 --basic-auth="projectdirname,/fullpath/environmentname/.htpasswd,realmname" /fullpath/environmentname
     157{{{#!sh
     158 $ tracd -p 8080 --basic-auth="project,/fullpath/environmentname/.htpasswd,realmname" /path/to/project
    158159}}}
    159160
    160161For example:
    161 {{{
    162  $ tracd -p 8080 --basic-auth="testenv,/srv/tracenv/testenv/.htpasswd,My Test Env" /srv/tracenv/testenv
     162{{{#!sh
     163 $ tracd -p 8080 --basic-auth="project,/srv/tracenv/testenv/.htpasswd,My Test Env" /path/to/project
    163164}}}
    164165''Note:'' You might need to pass "-m" as a parameter to htpasswd on some platforms (OpenBSD).
    165166
    166 === Digest authentication: Using a htdigest password file ===
     167=== Digest authentication: Using a htdigest password file
    167168
    168169If 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.
     
    170171Note that you can start tracd without the `--auth` argument, but if you click on the ''Login'' link you will get an error.
    171172
    172 === Generating Passwords Without Apache ===
    173 
    174 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.
    175 
    176 You can use this simple Python script to generate a '''digest''' password file:
    177 
    178 {{{
    179 #!python
    180 from optparse import OptionParser
    181 # The md5 module is deprecated in Python 2.5
    182 try:
    183     from hashlib import md5
    184 except ImportError:
    185     from md5 import md5
    186 realm = 'trac'
    187 
    188 # build the options
    189 usage = "usage: %prog [options]"
    190 parser = OptionParser(usage=usage)
    191 parser.add_option("-u", "--username",action="store", dest="username", type = "string",
    192                   help="the username for whom to generate a password")
    193 parser.add_option("-p", "--password",action="store", dest="password", type = "string",
    194                   help="the password to use")
    195 parser.add_option("-r", "--realm",action="store", dest="realm", type = "string",
    196                   help="the realm in which to create the digest")
    197 (options, args) = parser.parse_args()
    198 
    199 # check options
    200 if (options.username is None) or (options.password is None):
    201    parser.error("You must supply both the username and password")
    202 if (options.realm is not None):
    203    realm = options.realm
    204    
    205 # Generate the string to enter into the htdigest file
    206 kd = lambda x: md5(':'.join(x)).hexdigest()
    207 print ':'.join((options.username, realm, kd([options.username, realm, options.password])))
    208 }}}
    209 
    210 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):
    211 
    212 {{{
    213  $ python trac-digest.py -u username -p password >> c:\digest.txt
    214  $ tracd --port 8000 --auth=proj_name,c:\digest.txt,trac c:\path\to\proj_name

     176
     177Trac also provides `htpasswd` and `htdigest` scripts in `contrib`:
     178{{{#!sh
     179$ ./contrib/htpasswd.py -cb htpasswd user1 user1
     180$ ./contrib/htpasswd.py -b htpasswd user2 user2
     181}}}
     182
     183{{{#!sh
     184$ ./contrib/htdigest.py -cb htdigest trac user1 user1
     185$ ./contrib/htdigest.py -b htdigest trac user2 user2
    215186}}}
    216187
    217188==== Using `md5sum`
    218189It is possible to use `md5sum` utility to generate digest-password file:

     236=== Serving static content
    266237
    267238If `tracd` is the only web server used for the project,
     
    274245Example: given a `$TRAC_ENV/htdocs/software-0.1.tar.gz` file,
    275246the corresponding relative URL would be `/<project_name>/chrome/site/software-0.1.tar.gz`,
    276 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).
    277 
    278  ''Support for `htdocs:` TracLinks syntax was added in version 0.10''
     247which 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).

    280249=== Using tracd behind a proxy
     
    289258
    290259=== Authentication for tracd behind a proxy
    291 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.
     260It is convenient to provide central external authentication to your tracd instances, instead of using `--basic-auth`. There is some discussion about this in [trac:#9206].
    292261
    293262Below is example configuration based on Apache 2.2, mod_proxy, mod_authnz_ldap.
     
    295264First we bring tracd into Apache's location namespace.

    306275
    307276Then 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:
