    43Tracd is a lightweight standalone Trac web server.
    54It 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.
    65
    7 == Pros ==
     6== Pros
    87
    98 * Fewer dependencies: You don't need to install apache or any other web-server.
     
    1110 * 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).
    1211
    13 == Cons ==
     12== Cons
    1413
    1514 * Fewer features: Tracd implements a very simple web-server and is not as configurable or as scalable as Apache httpd.
    1615 * No native HTTPS support: [http://www.rickk.com/sslwrap/ sslwrap] can be used instead,
    17    or [http://trac.edgewall.org/wiki/STunnelTracd stunnel -- a tutorial on how to use stunnel with tracd] or Apache with mod_proxy.

    2120A single project on port 8080. (http://localhost:8080/)
    22 {{{
     21{{{#!sh
    2322 $ tracd -p 8080 /path/to/project

    3635
    3736An 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:
    38 {{{

    95 == Using Authentication ==
     93== Using Authentication
     94
     95Tracd 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
     97{{{#!div style="border: 1pt dotted; margin: 1em"
     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}}}
    96100
    97101Tracd 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.
    98102
    99103The general format for using authentication is:
    100 {{{
     104{{{#!sh
    101105 $ tracd -p port --auth="base_project_dir,password_file_path,realm" project_path
    102106}}}
     
    114118Examples:
    115119
    116 {{{
     120{{{#!sh
    117121 $ tracd -p 8080 \
    118122   --auth="project1,/path/to/passwordfile,mycompany.com" /path/to/project1
     
    120124
    121125Of course, the password file can be be shared so that it is used for more than one project:
    122 {{{
     126{{{#!sh
    123127 $ tracd -p 8080 \
    124128   --auth="project1,/path/to/passwordfile,mycompany.com" \
     
    128132
    129133Another way to share the password file is to specify "*" for the project name:
    130 {{{
     134{{{#!sh
    131135 $ tracd -p 8080 \
    132136   --auth="*,/path/to/users.htdigest,mycompany.com" \
     
    134138}}}
    135139
    136 === Basic Authorization: Using a htpasswd password file ===
     140=== Basic Authorization: Using a htpasswd password file
    137141This section describes how to use `tracd` with Apache .htpasswd files.
    138142
    139   Note: It is necessary (at least with Python 2.6) to install the fcrypt package in order to
    140   decode some htpasswd formats.  Trac source code attempt an `import crypt` first, but there
    141   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.
    142146
    143147To create a .htpasswd file use Apache's `htpasswd` command (see [#GeneratingPasswordsWithoutApache below] for a method to create these files without using Apache):
    144 {{{
     148{{{#!sh
    145149 $ sudo htpasswd -c /path/to/env/.htpasswd username
    146150}}}
    147151then for additional users:
    148 {{{
     152{{{#!sh
    149153 $ sudo htpasswd /path/to/env/.htpasswd username2
    150154}}}
    151155
    152156Then to start `tracd` run something like this:
    153 {{{
    154  $ 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
    155159}}}
    156160
    157161For example:
    158 {{{
    159  $ 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
    160164}}}
    161165''Note:'' You might need to pass "-m" as a parameter to htpasswd on some platforms (OpenBSD).
    162166
    163 === Digest authentication: Using a htdigest password file ===
     167=== Digest authentication: Using a htdigest password file
    164168
    165169If 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.
     
    167171Note that you can start tracd without the `--auth` argument, but if you click on the ''Login'' link you will get an error.
    168172
    169 === Generating Passwords Without Apache ===
    170 
    171 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.
    172 
    173 You can use this simple Python script to generate a '''digest''' password file:
    174 
    175 {{{
    176 #!python
    177 from optparse import OptionParser
    178 # The md5 module is deprecated in Python 2.5
    179 try:
    180     from hashlib import md5
    181 except ImportError:
    182     from md5 import md5
    183 realm = 'trac'
    184 
    185 # build the options
    186 usage = "usage: %prog [options]"
    187 parser = OptionParser(usage=usage)
    188 parser.add_option("-u", "--username",action="store", dest="username", type = "string",
    189                   help="the username for whom to generate a password")
    190 parser.add_option("-p", "--password",action="store", dest="password", type = "string",
    191                   help="the password to use")
    192 parser.add_option("-r", "--realm",action="store", dest="realm", type = "string",
    193                   help="the realm in which to create the digest")
    194 (options, args) = parser.parse_args()
    195 
    196 # check options
    197 if (options.username is None) or (options.password is None):
    198    parser.error("You must supply both the username and password")
    199 if (options.realm is not None):
    200    realm = options.realm
    201    
    202 # Generate the string to enter into the htdigest file
    203 kd = lambda x: md5(':'.join(x)).hexdigest()
    204 print ':'.join((options.username, realm, kd([options.username, realm, options.password])))
    205 }}}
    206 
    207 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):
    208 
    209 {{{
    210  $ python trac-digest.py -u username -p password >> c:\digest.txt
    211  $ 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}}}

     184$ ./contrib/htdigest.py -cb htdigest trac user1 user1
     185$ ./contrib/htdigest.py -b htdigest trac user2 user2
    212186}}}
    213187
    214188==== Using `md5sum`
    215189It is possible to use `md5sum` utility to generate digest-password file:

    263237
    264238If `tracd` is the only web server used for the project,
     
    271245Example: given a `$TRAC_ENV/htdocs/software-0.1.tar.gz` file,
    272246the corresponding relative URL would be `/<project_name>/chrome/site/software-0.1.tar.gz`,
    273 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).
    274 
    275  ''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).

    277249=== Using tracd behind a proxy
     
    286258
    287259=== Authentication for tracd behind a proxy
    288 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].
    289261
    290262Below is example configuration based on Apache 2.2, mod_proxy, mod_authnz_ldap.

    303275
    304276Then 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:
