Getting started
===============
Using Vagrant
-------------
This is the recommended approach, and is tested on OS X 10.10 as well as Ubuntu 14.04.
If your host is OS X, download VirtualBox from <http://download.virtualbox.org/virtualbox/4.3.30/VirtualBox-4.3.30-101610-OSX.dmg> and install it.
If your host is Ubuntu 14.04:
sudo apt-get install vagrant lxc lxc-templates cgroup-lite redir
Once that's done, simply change to your zulip directory and run `vagrant up` in your terminal. You can now visit <http://localhost:9991/> in your browser. To get shell access to the virtual machine running the server, use `vagrant ssh`.
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 of test databases:
./tools/postgres-init-test-db
./tools/do-destroy-rebuild-test-database
Run all tests:
./tools/test-all
This runs the linter plus all of our test suites; they can all be run
separately (just read `tools/test-all` to see them). You can also run
individual tests, e.g.:
./tools/test-backend zerver.test_bugdown.BugdownTest.test_inline_youtube
./tools/test-js-with-casper 10-navigation.js
Possible issues
===============
The Casper tests are flaky on the Virtualbox environment (probably due
to some performance-sensitive races). Until this issue is debugged,
you may need to rerun them to get them to pass.
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.
