Releasing

Run the tests and ensure they all pass
Update CHANGELOG.rst
Update the version in cassandra/__init__.py
- For beta releases, use a version like (2, 1, '0b1')
- For release candidates, use a version like (2, 1, '0rc1')
- When in doubt, follow PEP 440 versioning
Add the new version in docs.yaml
Commit the changelog and version changes
Tag the release. For example: git tag -a 1.0.0 -m 'version 1.0.0'
Push the commit and tag: git push --tags origin master

Upload the package to pypi:

python setup.py register
python setup.py sdist upload

On pypi, make the latest GA the only visible version
Update the docs (see below)
Append a 'postN' string to the version tuple in cassandra/__init__.py so that it looks like (x, y, z, 'postN')
- After a beta or rc release, this should look like (2, 1, '0b1', 'post0')
Commit and push
Update 'cassandra-test' branch to reflect new release
- this is typically a matter of merging or rebasing onto master
- test and push updated branch to origin
Update the JIRA versions: https://datastax-oss.atlassian.net/plugins/servlet/project-config/PYTHON/versions
Make an announcement on the mailing list

Building the Docs

Sphinx is required to build the docs. You probably want to install through apt, if possible:

sudo apt-get install python-sphinx

pip may also work:

sudo pip install -U Sphinx

To build the docs, run:

python setup.py doc

To upload the docs, checkout the gh-pages branch (it's usually easier to clone a second copy of this repo and leave it on that branch) and copy the entire contents all of docs/_build/X.Y.Z/* into the root of the gh-pages branch and then push that branch to github.

For example:

python setup.py doc
cp -R docs/_build/1.0.0-beta1/* ~/python-driver-docs/
cd ~/python-driver-docs
git add --all
git commit -m 'Update docs'
git push origin gh-pages

If docs build includes errors, those errors may not show up in the next build unless you have changed the files with errors. It's good to occassionally clear the build directory and build from scratch:

rm -rf docs/_build/*

Running the Tests

In order for the extensions to be built and used in the test, run:

python setup.py nosetests

You can run a specific test module or package like so:

python setup.py nosetests -w tests/unit/

You can run a specific test method like so:

python setup.py nosetests -w tests/unit/test_connection.py:ConnectionTest.test_bad_protocol_version

Seeing Test Logs in Real Time

Sometimes it's useful to output logs for the tests as they run:

python setup.py nosetests -w tests/unit/ --nocapture --nologcapture

Use tee to capture logs and see them on your terminal:

python setup.py nosetests -w tests/unit/ --nocapture --nologcapture 2>&1 | tee test.log

Specifying a Cassandra Version for Integration Tests

You can specify a cassandra version with the CASSANDRA_VERSION environment variable:

CASSANDRA_VERSION=2.0.9 python setup.py nosetests -w tests/integration/standard

You can also specify a cassandra directory (to test unreleased versions):

CASSANDRA_DIR=/home/thobbs/cassandra python setup.py nosetests -w tests/integration/standard

Specify a Protocol Version for Tests

The protocol version defaults to 1 for cassandra 1.2 and 2 otherwise. You can explicitly set it with the PROTOCOL_VERSION environment variable:

PROTOCOL_VERSION=3 python setup.py nosetests -w tests/integration/standard

Testing Multiple Python Versions

If you want to test all of python 2.6, 2.7, and pypy, use tox (this is what TravisCI runs):

tox

By default, tox only runs the unit tests because I haven't put in the effort to get the integration tests to run on TravicCI. However, the integration tests should work locally. To run them, edit the following line in tox.ini:

commands = {envpython} setup.py build_ext --inplace nosetests --verbosity=2 tests/unit/

and change tests/unit/ to tests/.

Running the Benchmarks

To run the benchmarks, pick one of the files under the benchmarks/ dir and run it:

python benchmarks/future_batches.py

There are a few options. Use --help to see them all:

python benchmarks/future_batches.py --help

Packaging for Cassandra

A source distribution is included in Cassandra, which uses the driver internally for cqlsh. To package a released version, checkout the tag and build a source zip archive:

python setup.py sdist --formats=zip

If packaging a pre-release (untagged) version, it is useful to include a commit hash in the archive name to specify the built version:

python setup.py egg_info -b-`git rev-parse --short HEAD` sdist --formats=zip

The file (dist/cassandra-driver-<version spec>.zip) is packaged with Cassandra in cassandra/lib/cassandra-driver-internal-only*zip.
