3 Patchwork uses the django framework - there is some background on deploying
4 django applications here:
6 http://www.djangobook.com/en/2.0/chapter12/
8 You'll need the following (applications used for patchwork development are
11 * A python interpreter
13 * A webserver (apache)
15 * A database server (postgresql, mysql)
16 * relevant python modules for the database server (e.g: python-mysqldb)
21 At present, I've tested with PostgreSQL and (to a lesser extent) MySQL
22 database servers. If you have any (positive or negative) experiences with
25 For the following commands, a $ prefix signifies that the command should be
26 entered at your shell prompt, and a > prefix signifies the command-line
27 client for your sql server (psql or mysql)
29 Create a database for the system, add accounts for two system users: the
30 web user (the user that your web server runs as) and the mail user (the
31 user that your mail server runs as). On Ubuntu these are
32 www-data and nobody, respectively.
34 As an alternative, you can use password-based login and a single database
35 account. This is described further down.
37 For PostgreSQL (ident-based)
43 - postgres uses the standard UNIX authentication, so these users
44 will only be accessible for processes running as the same username.
45 This means that no passwords need to be set.
47 For PostgreSQL (password-based)
49 $ createuser -PE patchwork
50 $ createdb -O patchwork patchwork
52 Once that is done, you need to tell Django about the new Database
53 settings, using local_settings.py (see below) to override the defaults
58 'ENGINE': 'django.db.backends.postgresql_psycopg2',
62 'PASSWORD': 'my_secret_password',
69 > CREATE DATABASE patchwork CHARACTER SET utf8;
70 > CREATE USER 'www-data'@'localhost' IDENTIFIED BY '<password>';
71 > CREATE USER 'nobody'@'localhost' IDENTIFIED BY '<password>';
73 Once that is done, you need to tell Django about the new Database
74 settings, using local_settings.py (see below) to override the defaults
79 'ENGINE': 'django.db.backends.mysql',
83 'PASSWORD': 'my_secret_password',
85 'TEST_CHARSET': 'utf8',
89 TEST_CHARSET is used when creating tables for the test suite. Without
90 it, tests checking for the correct handling of non-ASCII characters
96 Set up some initial directories in the patchwork base directory:
98 mkdir -p lib/packages lib/python
100 lib/packages is for stuff we'll download; lib/python is to add
101 to our python path. We'll symlink python modules into lib/python.
103 At the time of release, patchwork depends on django version 1.5 or
104 later. Your distro probably provides this. If not, do a:
107 git clone https://github.com/django/django.git -b stable/1.5.x
109 ln -s ../packages/django/django ./django
111 The patchwork/settings/*.py files contain default settings for patchwork,
112 you'll need to configure settings for your own setup.
114 Rather than editing these files (which will cause conflicts when you
115 update the base patchwork code), create a file 'production.py', based on
118 cp patchwork/settings/production.example.py \
119 patchwork/settings/production.py
121 and override or add settings as necessary. You'll need to define the
130 NOTIFICATION_FROM_EMAIL
132 You can generate the SECRET_KEY with the following python code:
134 import string, random
135 chars = string.letters + string.digits + string.punctuation
136 print repr("".join([random.choice(chars) for i in range(0,50)]))
138 If you wish to enable the XML-RPC interface, add the following to
139 your local_settings.py file:
143 Then, get patchwork to create its tables in your configured database:
145 PYTHONPATH=lib/python ./manage.py syncdb
147 and initialise the static content:
149 PYTHONPATH=lib/python ./manage.py collectstatic
151 and add privileges for your mail and web users. This is only needed if
152 you use the ident-based approach. If you use password-based database
153 authentication, you can skip this step.
156 psql -f lib/sql/grant-all.postgres.sql patchwork
159 mysql patchwork < lib/sql/grant-all.mysql.sql
164 Example apache configuration files are in lib/apache2/.
168 django has built-in support for WSGI, which supersedes the fastcgi
169 handler. It is thus the preferred method to run patchwork.
171 The necessary configuration for Apache2 may be found in
173 lib/apache2/patchwork.wsgi.conf.
175 You will need to install/enable mod_wsgi for this to work:
183 An example apache configuration file for mod_python is in:
185 lib/apache2/patchwork.mod_python.conf
187 However, mod_python and mod_php may not work well together. So, if your
188 web server is used for serving php files, the fastcgi method may suit
194 django has built-in support for fastcgi, which requires the
195 'flup' python module. An example configuration is in:
197 lib/apache2/patchwork.fastcgi.conf
199 - this also requires the mod_rewrite apache module to be loaded.
201 Once you have apache set up, you can start the fastcgi server with:
204 ./manage.py runfcgi method=prefork \
205 socket=/srv/patchwork/var/fcgi.sock \
206 pidfile=/srv/patchwork/var/fcgi.pid
209 4. Configure patchwork
210 Now, you should be able to administer patchwork, by visiting the
213 http://your-host/admin/
215 You'll probably want to do the following:
217 * Set up your projects
218 * Configure your website address (in the Sites) section
221 5. Subscribe a local address to the mailing list
223 You will need an email address for patchwork to receive email on - for
224 example - patchwork@, and this address will need to be subscribed to the
225 list. Depending on the mailing list, you will probably need to confirm the
226 subscription - temporarily direct the alias to yourself to do this.
229 6. Setup your MTA to deliver mail to the parsemail script
231 Your MTA will need to deliver mail to the parsemail script in the email/
232 directory. (Note, do not use the parsemail.py script directly). Something
233 like this in /etc/aliases is suitable for postfix:
235 patchwork: "|/srv/patchwork/patchwork/bin/parsemail.sh"
237 You may need to customise the parsemail.sh script if you haven't installed
238 patchwork in /srv/patchwork.
240 Test that you can deliver a patch to this script:
242 sudo -u nobody /srv/patchwork/patchwork/bin/parsemail.sh < mail
245 7. Set up the patchwork cron script
247 Patchwork uses a cron script to clean up expired registrations, and
248 send notifications of patch changes (for projects with this enabled).
250 Something like this in your crontab should work:
252 # m h dom mon dow command
254 DJANGO_SETTINGS_MODULE=patchwork.settings.production
255 */10 * * * * cd patchwork; python patchwork/bin/patchwork-cron.py
258 - the frequency should be the same as the NOTIFICATION_DELAY_MINUTES
259 setting, which defaults to 10 minutes.
262 8. Optional: Configure your VCS to automatically update patches
264 The tools directory of the patchwork distribution contains a file
265 named post-receive.hook which is an example git hook that can be
266 used to automatically update patches to the Accepted state when
267 corresponding comits are pushed via git.
269 To install this hook, simply copy it to the .git/hooks directory on
270 your server, name it post-receive, and make it executable.
272 This sample hook has support to update patches to different states
273 depending on which branch is being pushed to. See the STATE_MAP
274 setting in that file.
276 If you are using a system other than git, you can likely write a
277 similar hook using pwclient to update patch state. If you do write
278 one, please contribute it.
283 * __init__() got an unexpected keyword argument 'max_length'
285 - you're running an old version of django. If your distribution doesn't
286 provide a newer version, just download and extract django into
289 * ERROR: permission denied for relation patchwork_...
291 - the user that patchwork is running as (ie, the user of the web-server)
292 doesn't have access to the patchwork tables in the database. Check that
293 your web-server user exists in the database, and that it has permissions
296 * pwclient fails for actions that require authentication, but a username
297 and password is given in ~/.pwclientrc. Server reports "No authentication
300 - if you're using the FastCGI interface to apache, you'll need the
301 '-pass-header Authorization' option to the FastCGIExternalServer
302 configuration directive.
