    1 = Tracd
    2 
    3 Tracd is a lightweight standalone Trac web server.
    4 It 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.
    5 
    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).
    11 
    12 == Cons
    13 
    14  * 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 [trac:wiki:STunnelTracd stunnel -- a tutorial on how to use stunnel with tracd] or Apache with mod_proxy.
    17 
    18 == Usage examples
    19 
    20 A single project on port 8080. (http://localhost:8080/)
    21 {{{#!sh
    22  $ tracd -p 8080 /path/to/project
     1= Потрошувачка кошничка =
     2\\
     3|----------------------------------
     4{{{#!th align=right style="background: #ffd"
     5Use Case ID:
    236}}}
    24 Strictly 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
    26  $ tracd --hostname=localhost -p 8080 /path/to/project
     7{{{#!td align=left colspan=3
     85
    279}}}
    28 With more than one project. (http://localhost:8080/project1/ and http://localhost:8080/project2/)
    29 {{{#!sh
    30  $ tracd -p 8080 /path/to/project1 /path/to/project2
     10|----------------------------------
     11{{{#!th align=right style="background: #ffd"
     12Use Case Name:
    3113}}}
    32 
    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.
    35 
    36 An 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 {{{#!sh
    38  $ tracd -p 8080 -e /path/to
     14{{{#!td align=left colspan=3
     15Потрошувачка кошничка
    3916}}}
    40 
    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 {{{#!cmd
    48  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>"
    50  net start tracd
     17|----------------------------------
     18{{{#!th align=right style="background: #ffd"
     19Created By:
    5120}}}
    52 
    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}}}.
    54 
    55 If you want tracd to start automatically when you boot Windows, do:
    56 {{{#!cmd
    57  sc config tracd start= auto
     21{{{#!td align=left
     22Елена Стојанова \\
     23Иван Трајков
    5824}}}
    59 
    60 The spacing here is important.
    61 
    62 {{{#!div
    63 Once 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 
    66 Three (string) parameters are provided:
    67 ||!AppDirectory ||C:\Python26\ ||
    68 ||Application ||python.exe ||
    69 ||!AppParameters ||scripts\tracd-script.py -p 8080 ... ||
    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.)
     25{{{#!th align=right style="background: #ffd"

    74 
    75 For 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 {{{#!cmd
    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 net start tracd
     28{{{#!td align=left

     30Иван Трајков
    7931}}}
    80 
    81 === Option 2
    82 
    83 Use [http://trac-hacks.org/wiki/WindowsServiceScript WindowsServiceScript], available at [http://trac-hacks.org/ Trac Hacks]. Installs, removes, starts, stops, etc. your Trac service.
    84 
    85 === Option 3
    86 
    87 also cygwin's cygrunsrv.exe can be used:
    88 {{{#!sh
    89 $ cygrunsrv --install tracd --path /cygdrive/c/Python27/Scripts/tracd.exe --args '--port 8000 --env-parent-dir E:\IssueTrackers\Trac\Projects'
    90 $ net start tracd

    93 == Using Authentication
    94 
    95 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 
    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).
     36{{{#!td align=left
     3718.11.2015
    9938}}}
    100 
    101 Tracd 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.
    102 
    103 The general format for using authentication is:
    104 {{{#!sh
    105  $ tracd -p port --auth="base_project_dir,password_file_path,realm" project_path
     39{{{#!th align=right style="background: #ffd"
     40Date Last Updated:
    10641}}}
    107 where:
    108  * '''base_project_dir''': the base directory of the project specified as follows:
    109    * when serving multiple projects: ''relative'' to the `project_path`
    110    * when serving only a single project (`-s`): the name of the project directory
    111  Don't use an absolute path here as this won't work. ''Note:'' This parameter is case-sensitive even for environments on Windows.
    112  * '''password_file_path''': path to the password file
    113  * '''realm''': the realm name (can be anything)
    114  * '''project_path''': path of the project
    115 
    116  * **`--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.
    117 
    118 Examples:
    119 
    120 {{{#!sh
    121  $ tracd -p 8080 \
    122    --auth="project1,/path/to/passwordfile,mycompany.com" /path/to/project1
     42{{{#!td align=left
     4319.11.2015
    12344}}}
    124 
    125 Of course, the password file can be be shared so that it is used for more than one project:
    126 {{{#!sh
    127  $ tracd -p 8080 \
    128    --auth="project1,/path/to/passwordfile,mycompany.com" \
    129    --auth="project2,/path/to/passwordfile,mycompany.com" \
    130    /path/to/project1 /path/to/project2
     45|----------------------------------
     46{{{#!th align=right style="background: #ffd"
     47Actors:
    13148}}}
    132 
    133 Another way to share the password file is to specify "*" for the project name:
    134 {{{#!sh
    135  $ tracd -p 8080 \
    136    --auth="*,/path/to/users.htdigest,mycompany.com" \
    137    /path/to/project1 /path/to/project2

    140 === Basic Authorization: Using a htpasswd password file
    141 This section describes how to use `tracd` with Apache .htpasswd files.
    142 
    143   Note: It is necessary (at least with Python 2.6) to install the fcrypt package in order to
    144   decode some htpasswd formats.  Trac source code attempt an `import crypt` first, but there
    145   is no such package for Python 2.6. Only `SHA-1` passwords (since Trac 1.0) work without this module.
    146 
    147 To create a .htpasswd file use Apache's `htpasswd` command (see [#GeneratingPasswordsWithoutApache below] for a method to create these files without using Apache):
    148 {{{#!sh
    149  $ sudo htpasswd -c /path/to/env/.htpasswd username
     52|----------------------------------
     53{{{#!th align=right style="background: #ffd"
     54Description:
    15055}}}
    151 then for additional users:
    152 {{{#!sh
    153  $ sudo htpasswd /path/to/env/.htpasswd username2
     56{{{#!td align=left colspan=3
     57Корисникот ги додава книгите што сака да ги купи во кошничка.
    15458}}}
    155 
    156 Then to start `tracd` run something like this:
    157 {{{#!sh
    158  $ tracd -p 8080 --basic-auth="project,/fullpath/environmentname/.htpasswd,realmname" /path/to/project
     59|----------------------------------
     60{{{#!th align=right style="background: #ffd"
     61Trigger:
    15962}}}
    160 
    161 For example:
    162 {{{#!sh
    163  $ tracd -p 8080 --basic-auth="project,/srv/tracenv/testenv/.htpasswd,My Test Env" /path/to/project
     63{{{#!td align=left colspan=3
     64Кликање на копчето „Додади во кошничка“.
    16465}}}
    165 ''Note:'' You might need to pass "-m" as a parameter to htpasswd on some platforms (OpenBSD).
    166 
    167 === Digest authentication: Using a htdigest password file
    168 
    169 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.
    170 
    171 Note that you can start tracd without the `--auth` argument, but if you click on the ''Login'' link you will get an error.
    172 
    173 === Generating Passwords Without Apache
    174 
    175 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.
    176 
    177 Trac 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
     66|----------------------------------
     67{{{#!th align=right style="background: #ffd"
     68Preconditions:

    182 
    183 {{{#!sh
    184 $ ./contrib/htdigest.py -cb htdigest trac user1 user1
    185 $ ./contrib/htdigest.py -b htdigest trac user2 user2
     70{{{#!td align=center colspan=3
     71/
    18672}}}
    187 
    188 ==== Using `md5sum`
    189 It is possible to use `md5sum` utility to generate digest-password file:
    190 {{{#!sh
    191 user=
    192 realm=
    193 password=
    194 path_to_file=
    195 echo ${user}:${realm}:$(printf "${user}:${realm}:${password}" | md5sum - | sed -e 's/\s\+-//') > ${path_to_file}

    231 
    232 Use the -d option so that tracd doesn't hang if you close the terminal window where tracd was started.
    233 
    234 == Tips
    235 
    236 === Serving static content
    237 
    238 If `tracd` is the only web server used for the project,
    239 it can also be used to distribute static content
    240 (tarballs, Doxygen documentation, etc.)
    241 
    242 This static content should be put in the `$TRAC_ENV/htdocs` folder,
    243 and is accessed by URLs like `<project_URL>/chrome/site/...`.
    244 
    245 Example: given a `$TRAC_ENV/htdocs/software-0.1.tar.gz` file,
    246 the corresponding relative URL would be `/<project_name>/chrome/site/software-0.1.tar.gz`,
    247 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).
    248 
    249 === Using tracd behind a proxy
    250 
    251 In some situations when you choose to use tracd behind Apache or another web server.
    252 
    253 In 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.
    254 
    255 If 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.
    256 
    257 See also [trac:TracOnWindowsIisAjp], [trac:TracNginxRecipe].
    258 
    259 === Authentication for tracd behind a proxy
    260 It 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].
    261 
    262 Below is example configuration based on Apache 2.2, mod_proxy, mod_authnz_ldap.
    263 
    264 First we bring tracd into Apache's location namespace.
    265 
    266 {{{#!apache
    267 <Location /project/proxified>
    268         Require ldap-group cn=somegroup, ou=Groups,dc=domain.com
    269         Require ldap-user somespecificusertoo
    270         ProxyPass http://localhost:8101/project/proxified/
    271         # Turns out we don't really need complicated RewriteRules here at all
    272         RequestHeader set REMOTE_USER %{REMOTE_USER}s
    273 </Location>
     80|----------------------------------
     81{{{#!th align=right style="background: #ffd"
     82Flow of events:
    27483}}}
    275 
    276 Then 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:
    277 {{{#!python
    278 from trac.core import *
    279 from trac.config import BoolOption
    280 from trac.web.api import IAuthenticator
    281 
    282 class MyRemoteUserAuthenticator(Component):
    283 
    284     implements(IAuthenticator)
    285 
    286     obey_remote_user_header = BoolOption('trac', 'obey_remote_user_header', 'false',
    287                """Whether the 'Remote-User:' HTTP header is to be trusted for user logins
    288                 (''since ??.??').""")
    289 
    290     def authenticate(self, req):
    291         if self.obey_remote_user_header and req.get_header('Remote-User'):
    292             return req.get_header('Remote-User')
    293         return None
