Clear message

This page is dedicated to development of Python bug tracker instance at http://bugs.python.org/
We have a meta tracker for current issues and DesiredTrackerFeatures page for recording ideas. See also TrackerDevelopmentPlanning.

Very quick start for impatient

Install Vagrant and VirtualBox:

hg clone https://bitbucket.org/techtonik/pydotorg-bpo
cd pydotorg-bpo
vagrant up
vagrant -c ./server-start.sh

Requirements

This configuration is deployed on production server, so it is good to stick it for development as well:

http://bugs.python.org/ (python-dev tracker instance or configuration) is running PostgreSQL on backed, because it has the best performance for large installations. Besides, there is at least one place in the python-dev config with hardcoded dependency on the SQL-based backed.

Getting the source

Get patched version of Roundup tracker from here:

Tracker configuration for http://bugs.python.org/ (called 'tracker home', 'instance' or `environment) is here:

Other tracker configurations

There are several Roundup trackers used for Python development. Configuration for them is maintained in http://hg.python.org/tracker/ repositories:

Setup bugs.python.org instance

Install patched Roundup

Clone code and switch to bugs.python.org branch before installing. Here it is installed to hardcoded system-wide location at /opt/tracker-roundup/.

cd roundup
hg up bugs.python.org
sudo python setup.py install --prefix /opt/tracker-roundup/

Checkout the python-dev instance

Checkout the Rietveld integration (optional)

If you want to work on Rietveld code review tool, check out the django-gae2django and rietveld clones in the python-dev/ directory:

After getting the clones remember to update the branches to bugs.python.org:

cd django-gae2django
hg up bugs.python.org
cd ..
cd rietveld
hg up bugs.python.org

In addition, Django needs to be installed; e.g. the Django 1.2 or 1.3 Debian packages work fine.

Install psycopg2 (PostgreSQL access library for Python)

For Debian/Ubuntu:

sudo apt-get install python-psycopg2

For other systems, follow instructions from psycopg2 site.

Install and configure PostgreSQL

Other backends may work, but it is recommended to keep development environment close to production.

It has been reported that 8.2, 8.3, 8.4, and 9.1 work well. See UpgradingPostgreSQL if you need to upgrade version.

Access control in PostgreSQL is tricky. You need to know Unix user, under which you run Roundup, setup access for him to PostgreSQL database, and add PostgreSQL user that you've configured in Roundup's configuration.

For a development environment the easiest way is to allow any user from localhost to connect as any database user. This can be accomplished by editing pg_hba.conf (usually found in /etc/postgresql/9.x/main/ in Linux or /Library/PostgreSQL/9.x/data/ in Mac OS X -- you might need privileges to edit it). The end of the file should look like this (the four changed lines are preceded by ##):

# Database administrative login by UNIX sockets
##local   all         postgres                          ident
local   all         postgres                          trust

# TYPE  DATABASE    USER        CIDR-ADDRESS          METHOD

# "local" is for Unix domain socket connections only
##local   all         all                               ident
local   all         all                               trust
# IPv4 local connections:
##host    all         all         127.0.0.1/32          md5
host    all         all         127.0.0.1/32          trust
# IPv6 local connections:
##host    all         all         ::1/128               md5
host    all         all         ::1/128               trust

PLEASE NOTE: This is not a secure configuration on a multi-user machine.

After the change in pg_hba.conf, reload your postgreSQL database to make sure it knows about your new access configuration. Something similar to

sudo /etc/init.d/postgresql reload

should do the trick on Unix-like platforms.

On Mac OS X, do sudo su - postgres. Then use pg_ctl to restart the server:

/Library/PostgreSQL/9.x/bin/pg_ctl restart -D /Library/PostgreSQL/9.x/data

Create a database user that is allowed to create databases. This user will be used when roundup connects to the database.

$ psql -U postgres
postgres=# create user roundup;
postgres=# alter user roundup with createdb;

Configure your Development Roundup Instance

Now enter the python-dev directory, and create the 'db' directory, as well as the db/backend_name file which decides which backend (i.e. database type) to use:

cd python-dev
mkdir db
echo postgresql > db/backend_name

Note: the db dir contains all the messages and files attached to issues, and it's removed and recreated every time you run roundup-admin init.

Copy python-dev/config.ini.template into config.ini and detectors/config.ini.template into detectors/config.ini:

cp config.ini.template config.ini
cp detectors/config.ini.template detectors/config.ini

The former will let you configure your roundup instance; the latter, detectors such as irker, busybody, or tellteam.

In config.ini pay special attention to settings marked with NO DEFAULT.

config.ini.template already contains some useful default values for a development enviroment, for example

debug = debugmail.txt

at the end of the [mail] section saves outgoing mails on a local file; and

debug = on

at the end of the [web] section shows tracebacks in the browser instead of having them sent by email.

Initialize your roundup instance:

/opt/tracker-roundup/bin/roundup-admin -i <your python-dev directory> init

Provide a password for the 'admin' user when asked for.

Note: you have to provide the full path to your python-dev directory, otherwise the command will fail.

If you are getting the error:

Start your roundup instance:

/opt/tracker-roundup/bin/roundup-server -p 9999 python-dev=<your python-dev directory>

You will have to use this command every time you (re)start roundup, so it's easier to create an alias for it with:

alias start-roundup='/opt/tracker-roundup/bin/roundup-server -p 9999 python-dev=<your python-dev directory>'

It might be a good idea to create another alias for roundup admin too:

alias admin-roundup='/opt/tracker-roundup/bin/roundup-admin -i <your python-dev directory>'

then add them to your .bashrc (or ~/.profile in Mac OS X)

You should now be able to browse http://localhost:9999/python-dev/ and get a roundup instance that looks just like http://bugs.python.org, except for some missing new values for fields like Stages and Keywords. It's possible to replace initial_data.py with an updated version so that your fields will have values that match those currently present in the Python Tracker.

The IDs for values in a given field might be different from those in the Python Tracker. This should only be a problem if you try to import CSV files from one tracker into the other.

Create an user from User->register in the left sidebar. Note that if you have set debug = debugmail.txt as suggested above, you will have to open the file and copy the URL in the browser (make sure to replace =3D with = in the URL and to remove the trailing = where the url is broken at the end of the line). You can then use roundup-admin to set developer privileges for it:

/opt/tracker-roundup/bin/roundup-admin -i <your python-dev directory>
Roundup 1.5.0 ready for input.
Type "help" for help.
roundup> display user3
...
roundup> set user3 roles=User,Developer,Coordinator
roundup> commit
roundup>

You can find your user id clicking on "Your Details" in the left sidebar and then looking at the address bar (it should show something similar to http://localhost:9999/python-dev/user3).

Rietveld Setup

The Roundup and Rietveld data are stored in the same Postgres database. After the Roundup tables have been created, add to python-dev/config.ini:

[django]
secret_key = <the_secret_key>

To generate the secret key you can use an online django secret key generator, or just put an arbitrary string.

Before continuing make sure to check with "hg branch" that the branch is "bugs.python.org" on both the rietveld and the django-gae2django clones.

cd rietveld
python manage.py syncdb
cd ..
PYTHONPATH=detectors/:/opt/tracker-roundup/lib/python2.7/site-packages/ python scripts/initrietveld

If you are upgrading from an older installation, review the revision history of rietveld/migration.

To run the Rietveld code, do

python manage.py runserver

This will run Rietveld by default on port 8000. Alternatively to the development server, you can also configure your web server to run rietveld.wsgi under the /review URL.

Rietveld patchset creation is an offline activity. If you have new patches in your tracker instance, run

scripts/addpatchsets

If you get errors like:

django.db.utils.DatabaseError: column codereview_repository.guid does not exist
LINE 1: ...itory"."url", "codereview_repository"."owner_id", "coderevie...

you can try to remove the table(s) from the database and re-run syncdb and initrietveld:

$ psql -U roundup
psql (9.1.4)
Type "help" for help.

roundup=> \d codereview_repository
     Table "public.codereview_repository"
... check here if some column is missing and if it is drop the table ...
roundup=> drop table codereview_repository cascade;
NOTICE:  drop cascades to constraint codereview_branch_repo_id_fkey on table codereview_branch
DROP TABLE
roundup=> \q

$ cd rietveld
$ python manage.py syncdb

Creating table codereview_repository

Installing indexes ...
No fixtures found.
$ cd ..
$ PYTHONPATH=detectors/:/opt/tracker-roundup/lib/python2.7/site-packages/ python scripts/initrietveld

irker setup

irkerd is a daemon that sends notification on IRC whenever a message is added or an issue is created, and replaces the CIA.vc service.

You will need:

* irker: http://www.catb.org/esr/irker/

* the irc package: http://pypi.python.org/pypi/irc/

To install them you can use:

wget http://pypi.python.org/packages/source/i/irc/irc-5.0.1.zip
unzip irc-5.0.1.zip
cd irc-5.0.1/
sudo python setup.py install
cd ..

wget http://www.catb.org/~esr/irker/irker-1.17.tar.gz
tar -zxvf irker-1.17.tar.gz

If you get the error ImportError: No module named hgtools.plugins during the sudo python setup.py install, you can try the command again and it should automagically work.

Make sure that you have listed the address of the channels that should receive the messages in detectors/config.ini, e.g.:

[irker]
channels = irc://chat.freenode.net/python-dev

To start irker use:

cd irker-1.17/
./irkerd &

You can also use ./irkerd -d3 to see debugging messages.

Resources for Tracker Development

Getting Help

Subscribe to and ask your question on the tracker-discuss mailing list. See http://mail.python.org/mailman/listinfo/tracker-discuss

Since the Python Tracker is a slightly modified version of Roundup, both Roundup's Documentation and issue tracker contain relevant information about how the Python Tracker works and problems one might find working with its code.

Using roundup-admin

To start roundup-admin interactively use:

/opt/tracker-roundup/bin/roundup-admin -i <your python-dev directory>

To get the list of users, issues, msgs, files, etc:

roundup> list user

To see info about a specific user, issue, msg, file, etc:

roundup> display userXXX

To change the role of an user:

roundup> set userXXX roles=User,Developer
roundup> commit

Users have limited privileges and can edit just some of the fields in the issue page. Developers can edit all the fields and remove msgs and files. Coordinators can also mark/unmark messages as spam and change some of the settings of other users (e.g. if they submitted the contributor agreement).

To add back a message deleted accidentally:

roundup> set issueXXX messages=+YYY
roundup> commit

The message will be added back in the right position. (This should be equivalent to b.p.o/issueXXX?@action=edit&@add@messages=YYY, but this doesn't seem to work.)

The Meta Tracker

A Meta Tracker is available for handling bugs and features requests for the Python Tracker.

Setting Up an Instance in a VirtualEnv

See TrackerDevelopmentVirtualEnv.

The Test Tracker

Public test instance of the Python tracker: http://bot.bio.br/python-dev/ (currently offine)

Instance that attempts to match the code used in http://bugs.python.org to allow testing, reproducing and verifying fixes for tracker bugs. Can also be used as a sandbox by users interested in learning about Developer, Coordinator or Admin tasks and features. Testing new content (e.g. Components or Statuses) is OK, but new features show be tested in the Experimental Tracker instead.

Currently the email system is disabled (redirected to file), so people interested in having an account there to test new features should email tracker-discuss to get one. Maintained by DanielDiniz.

The Experimental Tracker

Modified version of the Python tracker: http://bot.bio.br/python-dev-exp/ (currently offline)

It's an instance to showcase and test new features.

New features (2009-04-18):

Currently the email system is disabled (redirected to file), so people interested in having an account there to test new features should email tracker-discuss to get one. Maintained by DanielDiniz.

There is also a list of additional DesiredTrackerFeatures for which no patches yet exist.

Getting Your Own Jython Tracker
