Kudzu 0.1

Set of utilities for better logging in WSGI applications

Kudzu provides WSGI middleware and logging handlers which:

• Read or generate unique ID for each request and include this request ID in emitted log records.

• Sends request ID in response using X-Request-ID header. This ID is also made globally available and can included when calling other applications or components.

• Logs all requests and responses using Python standard logging.

Kudzu is framework independent and it is compatible with both Python 2 (tested with 2.6 and 2.7) and Python 3 (tested with 3.3 and 3.4).

Installation

Kudzu can be installed using pip (or easy_install) from PyPI:

$ pip install kudzu

Alternatively you can download and extract tarball and install the package manually:

$ python setup.py install

Placing the package to your PYTHONPATH should also work.

Example usage

# Apply middleware to WSGI application
application = kudzify_app(application)

# Include request ID and remote address in log records
kudzify_logger(format='[%(addr)s|%(rid)s] %(levelname)s:%(message)s')

See example.py for more information.

Testing

Tests for all supported Python versions can be run using Tox:

$ tox

Alternativelly you can install Kudzu with test dependencies pytest and Werkzeug and run tests manually:

$ py.test
