     1= Tracd
    22
    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.
    1515 * 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.

    1919
    2020A single project on port 8080. (http://localhost:8080/)
    21 {{{
     21{{{#!sh
    2222 $ tracd -p 8080 /path/to/project
    2323}}}
    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.
    25 {{{
     24Strictly speaking this will make your Trac accessible to everybody from your network rather than ''localhost only''. To truly limit it use the `--hostname` option.
     25{{{#!sh
    2626 $ tracd --hostname=localhost -p 8080 /path/to/project
    2727}}}
    2828With more than one project. (http://localhost:8080/project1/ and http://localhost:8080/project2/)
    29 {{{
     29{{{#!sh
    3030 $ tracd -p 8080 /path/to/project1 /path/to/project2
    3131}}}
    … …  
    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
    3939}}}
    4040
    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 ===
     41There 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].
     42
     43To exit the server on Windows, be sure to use `CTRL-BREAK` -- using `CTRL-C` will leave a Python process running in the background.
     44
     45== Installing as a Windows Service
     46
     47=== Option 1
    4648To install as a Windows service, get the [http://www.google.com/search?q=srvany.exe SRVANY] utility and run:
    47 {{{
     49{{{#!cmd
    4850 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>"
     51 reg add HKLM\SYSTEM\CurrentControlSet\Services\tracd\Parameters /v Application /d "\"C:\path\to\python.exe\" \"C:\path\to\python\scripts\tracd.exe\" <your tracd parameters>"
    5052 net start tracd
    5153}}}
    5254
    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}}}.
     55{{{#!div style="border: 1pt dotted; margin: 1em;"
     56**Attention:** Do not use `tracd.exe` directly.  Instead register `python.exe` directly with `tracd.exe` 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`.
     57}}}
    5458
    5559If you want tracd to start automatically when you boot Windows, do:
    56 {{{
     60{{{#!cmd
    5761 sc config tracd start= auto
    5862}}}
    … …  
    6569
    6670Three (string) parameters are provided:
    67 ||!AppDirectory ||C:\Python26\ ||
     71||!AppDirectory ||C:\Python27\ ||
    6872||Application ||python.exe ||
    69 ||!AppParameters ||scripts\tracd-script.py -p 8080 ... ||
     73||!AppParameters ||scripts\tracd.exe -p 8080 ... ||
    7074
    7175Note 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.
    … …  
    7478
    7579For 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>"

     80{{{#!cmd
     81"C:\path\to\winserv.exe" install tracd -displayname "tracd" -start auto "C:\path\to\python.exe" c:\path\to\python\scripts\tracd.exe <your tracd parameters>"
    7982net start tracd
    8083}}}
    8184
    82 === Option 2 ===
     85=== Option 2
    8386
    8487Use [http://trac-hacks.org/wiki/WindowsServiceScript WindowsServiceScript], available at [http://trac-hacks.org/ Trac Hacks]. Installs, removes, starts, stops, etc. your Trac service.
    8588
    86 == Using Authentication ==
     89=== Option 3
     90
     91also cygwin's cygrunsrv.exe can be used:
     92{{{#!sh
     93$ cygrunsrv --install tracd --path /cygdrive/c/Python27/Scripts/tracd.exe --args '--port 8000 --env-parent-dir E:\IssueTrackers\Trac\Projects'
     94$ net start tracd
     95}}}
     96
     97== Using Authentication
     98
     99Tracd 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)
     100
     101{{{#!div style="border: 1pt dotted; margin: 1em"
     102**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).
     103}}}
    87104
    88105Tracd 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.
    89106
    90107The general format for using authentication is:
    91 {{{
     108{{{#!sh
    92109 $ tracd -p port --auth="base_project_dir,password_file_path,realm" project_path
    93110}}}
    … …  
    105122Examples:
    106123
    107 {{{
     124{{{#!sh
    108125 $ tracd -p 8080 \
    109126   --auth="project1,/path/to/passwordfile,mycompany.com" /path/to/project1
    … …  
    111128
    112129Of course, the password file can be be shared so that it is used for more than one project:
    113 {{{
     130{{{#!sh
    114131 $ tracd -p 8080 \
    115132   --auth="project1,/path/to/passwordfile,mycompany.com" \
    … …  
    119136
    120137Another way to share the password file is to specify "*" for the project name:
    121 {{{
     138{{{#!sh
    122139 $ tracd -p 8080 \
    123140   --auth="*,/path/to/users.htdigest,mycompany.com" \
    … …  
    125142}}}

    127 === Basic Authorization: Using a htpasswd password file ===
     144=== Basic Authorization: Using a htpasswd password file
    128145This section describes how to use `tracd` with Apache .htpasswd files.
    129146
     147  Note: On Windows It is necessary to install the [https://pypi.python.org/pypi/passlib passlib]
     148  package in order to decode some htpasswd formats. Only `SHA-1` passwords (since Trac 1.0)
     149  work without this module.
     150
    130151To create a .htpasswd file use Apache's `htpasswd` command (see [#GeneratingPasswordsWithoutApache below] for a method to create these files without using Apache):
    131 {{{
     152{{{#!sh
    132153 $ sudo htpasswd -c /path/to/env/.htpasswd username
    133154}}}
    134155then for additional users:
    135 {{{
     156{{{#!sh
    136157 $ sudo htpasswd /path/to/env/.htpasswd username2
    137158}}}
    138159
    139160Then to start `tracd` run something like this:
    140 {{{
    141  $ tracd -p 8080 --basic-auth="projectdirname,/fullpath/environmentname/.htpasswd,realmname" /fullpath/environmentname
     161{{{#!sh
     162 $ tracd -p 8080 --basic-auth="project,/fullpath/environmentname/.htpasswd,realmname" /path/to/project
    142163}}}
    143164
    144165For example:
    145 {{{
    146  $ tracd -p 8080 --basic-auth="testenv,/srv/tracenv/testenv/.htpasswd,My Test Env" /srv/tracenv/testenv
     166{{{#!sh
     167 $ tracd -p 8080 --basic-auth="project,/srv/tracenv/testenv/.htpasswd,My Test Env" /path/to/project
    147168}}}
    148169''Note:'' You might need to pass "-m" as a parameter to htpasswd on some platforms (OpenBSD).
    149170
    150 === Digest authentication: Using a htdigest password file ===
     171=== Digest authentication: Using a htdigest password file
    151172
    152173If 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.
    153174
    154 Note that you can start tracd without the --auth argument, but if you click on the ''Login'' link you will get an error.
    155 
    156 === Generating Passwords Without Apache ===
    157 
    158 Basic 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 
    160 You can use this simple Python script to generate a '''digest''' password file:
    161 
    162 {{{
    163 #!python
    164 from optparse import OptionParser
    165 # The md5 module is deprecated in Python 2.5
    166 try:
    167     from hashlib import md5
    168 except ImportError:
    169     from md5 import md5
    170 realm = 'trac'
    171 
    172 # build the options
    173 usage = "usage: %prog [options]"
    174 parser = OptionParser(usage=usage)
    175 parser.add_option("-u", "--username",action="store", dest="username", type = "string",
    176                   help="the username for whom to generate a password")
    177 parser.add_option("-p", "--password",action="store", dest="password", type = "string",
    178                   help="the password to use")
    179 parser.add_option("-r", "--realm",action="store", dest="realm", type = "string",
    180                   help="the realm in which to create the digest")
    181 (options, args) = parser.parse_args()
    182 
    183 # check options
    184 if (options.username is None) or (options.password is None):
    185    parser.error("You must supply both the username and password")
    186 if (options.realm is not None):
    187    realm = options.realm
    188    
    189 # Generate the string to enter into the htdigest file
    190 kd = lambda x: md5(':'.join(x)).hexdigest()
    191 print ':'.join((options.username, realm, kd([options.username, realm, options.password])))
    192 }}}
    193 
    194 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):
    195 
    196 {{{
    197  $ python trac-digest.py -u username -p password >> c:\digest.txt
    198  $ tracd --port 8000 --auth=proj_name,c:\digest.txt,trac c:\path\to\proj_name
     175Note that you can start tracd without the `--auth` argument, but if you click on the ''Login'' link you will get an error.
     176
     177=== Generating Passwords Without Apache
     178
     179Basic 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.
     180
     181Trac also provides `htpasswd` and `htdigest` scripts in `contrib`:
     182{{{#!sh
     183$ ./contrib/htpasswd.py -cb htpasswd user1 user1
     184$ ./contrib/htpasswd.py -b htpasswd user2 user2
     185}}}
     186
     187{{{#!sh
     188$ ./contrib/htdigest.py -cb htdigest trac user1 user1
     189$ ./contrib/htdigest.py -b htdigest trac user2 user2
    199190}}}
    200191
    201192==== Using `md5sum`
    202193It is possible to use `md5sum` utility to generate digest-password file:
     194{{{#!sh
     195user=
     196realm=
     197password=
     198path_to_file=
     199echo ${user}:${realm}:$(printf "${user}:${realm}:${password}" | md5sum - | sed -e 's/\s\+-//') > ${path_to_file}
     200}}}

     204Here's the online help, as a reminder (`tracd -h` or `tracd --help`):
    203205{{{
    204  $ printf "${user}:trac:${password}" | md5sum - >>user.htdigest

     248
     249Use the -d option so that tracd doesn't hang if you close the terminal window where tracd was started.

     251== Tips
     252
     253=== Serving static content
    239254
    240255If `tracd` is the only web server used for the project,
    … …  
    247262Example: given a `$TRAC_ENV/htdocs/software-0.1.tar.gz` file,
    248263the corresponding relative URL would be `/<project_name>/chrome/site/software-0.1.tar.gz`,
    249 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).
    250 
    251  ''Support for `htdocs:` TracLinks syntax was added in version 0.10''
     264which 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).

     277It 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].
     278
     279Below is example configuration based on Apache 2.2, mod_proxy, mod_authnz_ldap.
     280
     281First we bring tracd into Apache's location namespace.
     282
     283{{{#!apache
     284<Location /project/proxified>
     285        Require ldap-group cn=somegroup, ou=Groups,dc=domain.com
     286        Require ldap-user somespecificusertoo
     287        ProxyPass http://localhost:8101/project/proxified/
     288        # Turns out we don't really need complicated RewriteRules here at all
     289        RequestHeader set REMOTE_USER %{REMOTE_USER}s
     290</Location>
     291}}}
     292
     293Then 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:
     294{{{#!python
     295from trac.core import *
     296from trac.config import BoolOption
     297from trac.web.api import IAuthenticator
     298
     299class MyRemoteUserAuthenticator(Component):
     300
     301    implements(IAuthenticator)
     302
     303    obey_remote_user_header = BoolOption('trac', 'obey_remote_user_header', 'false',
     304               """Whether the 'Remote-User:' HTTP header is to be trusted for user logins
     305                (''since ??.??').""")
     306
     307    def authenticate(self, req):
     308        if self.obey_remote_user_header and req.get_header('Remote-User'):
     309            return req.get_header('Remote-User')
     310        return None
     311
     312}}}
     313
     314Add this new parameter to your TracIni:
     315{{{#!ini
     316[trac]
     317...
     318obey_remote_user_header = true
     319...
     320}}}
     321
     322Run tracd:
     323{{{#!sh
     324tracd -p 8101 -s proxified --base-path=/project/proxified
     325}}}
     326
     327Note that if you want to install this plugin for all projects, you have to put it in your [TracPlugins#Plugindiscovery global plugins_dir] and enable it in your global trac.ini.
     328
     329Global config (e.g. `/srv/trac/conf/trac.ini`):
     330{{{#!ini
     331[components]
     332remote-user-auth.* = enabled
     333[inherit]
     334plugins_dir = /srv/trac/plugins
     335[trac]
     336obey_remote_user_header = true
     337}}}
     338
     339Environment config (e.g. `/srv/trac/envs/myenv`):
     340{{{#!ini
     341[inherit]
     342file = /srv/trac/conf/trac.ini
     343}}}
     344
     345=== Serving a different base path than /
    264346Tracd supports serving projects with different base urls than /<project>. The parameter name to change this is
    265 {{{
     347{{{#!sh
    266348 $ tracd --base-path=/some/path
    267349}}}
