Getting started
===============

Using Vagrant
-------------

This is the recommended approach, but is only supported on Ubuntu 14.04.

  sudo apt-get install vagrant lxc lxc-templates cgroup-lite redir
  vagrant plugin install vagrant-lxc
  vagrant up --provider=lxc
  vagrant ssh
  # Now inside the container
  sudo apt-get update
  sudo apt-get install python-pbs
  cd /srv/zulip && python provision.py

To run the development server:
  vagrant ssh -- -L9991:localhost:9991
  # Now inside the container
  cd /srv/zulip
  source /srv/zulip-venv/bin/activate
  ./tools/run-dev.py

You can now visit <http://localhost:9991/> in your browser.

By hand
-------

Install the following non-Python dependencies:
 * libffi-dev — needed for some Python extensions
 * postgresql 9.1 or later — our database (also install development headers)
 * memcached (and headers)
 * rabbitmq-server
 * libldap2-dev
 * python-dev
 * redis-server — rate limiting
 * tsearch-extras — better text search

On Debian or Ubuntu systems:
  sudo apt-get install libffi-dev memcached rabbitmq-server libldap2-dev redis-server postgresql-server-dev-all libmemcached-dev

  # If on 12.04 or wheezy:
  sudo apt-get install postgresql-9.1
  wget https://dl.dropboxusercontent.com/u/283158365/zuliposs/postgresql-9.1-tsearch-extras_0.1.2_amd64.deb
  sudo dpkg -i postgresql-9.1-tsearch-extras_0.1.2_amd64.deb

  # If on 14.04:
  sudo apt-get install postgresql-9.3
  wget https://dl.dropboxusercontent.com/u/283158365/zuliposs/postgresql-9.3-tsearch-extras_0.1.2_amd64.deb
  sudo dpkg -i postgresql-9.3-tsearch-extras_0.1.2_amd64.deb

  # If on 15.04 or jessie:
  sudo apt-get install postgresql-9.4
  wget https://dl.dropboxusercontent.com/u/283158365/zuliposs/postgresql-9.4-tsearch-extras_0.1_amd64.deb
  sudo dpkg -i postgresql-9.4-tsearch-extras_0.1_amd64.deb

  # Then, all versions:
  pip install -r requirements.txt
  ./scripts/setup/configure-rabbitmq
  ./tools/postgres-init-db
  ./tools/do-destroy-rebuild-database

To start the development server:
  ./tools/run-dev.py

… and hit http://localhost:9991/.


Running the test suite
======================

One-time setup:
  ./tools/postgres-init-test-db
  ./tools/do-destroy-rebuild-test-database

Backend tests:
  ./tools/test-backend

Frontend tests: TBD

Possible issues
===============

When running the test suite, if you get an error like this:
    sqlalchemy.exc.ProgrammingError: (ProgrammingError) function ts_match_locs_array(unknown, text, tsquery) does not exist
    LINE 2: ...ECT message_id, flags, subject, rendered_content, ts_match_l...
                                                                 ^
… then you need to install tsearch-extras, described above. Afterwards, re-run the init*-db and the do-destroy-rebuild*-database scripts.
