Mailing List Stats Build Status

Description

Mailing List Stats (mlstats) is a tool to parse and analyze mail boxes. It is useful to retrieve and analyze mailing list archives. The parsed mail boxes are stored in a database.

mlstats is able to retrieve mailing lists from the web, and store the data of every email in a database, from where to obtain different kind of reports.

License

Licensed under GNU General Public License (GPL), version 2 or later.

Download

Releases:

Latest version:

$ git clone git://github.com/MetricsGrimoire/MailingListStats.git

Requirements

mlstats requires "SQLAlchemy" to work with multiple database engines. mlstats has been tested against Sqlite3, MySQL and PostgreSQL.

To work with MySQL or PostgreSQL, mlstats needs the following extra dependencies:

  • MySQL:
  • PostgreSQL:
    • Python package "psycopg2"
    • PostgreSQL-Server (tested with 8.4 and 9.x series)

Installation

You can install mlstats running setup.py script:

$ python setup.py install

mlstats can be installed without privileges, use the --prefix option to indicate the directory where mlstats will be installed. For more details, take a look at the help of the installer:

$ python setup.py install --help

You are ready to use mlstats.

Running MLStats

In general configuration is applied by command line arguments or environment variables. Checkout existing arguments and environment variables via mlstats --help.

Basic Setup Using Sqlite

To run mlstats without the hassle of setting a database, you can use the builtin Sqlite3.

$ mlstats --db-engine=slqlite --db-name=MLS-DATA.DB http://URL-OF-YOUR-LIST/

Just replace the text in ALL CAPS with your database name, and mailing list URL to work on.

In this example, if the file MLS-DATA.DB does not exists, mlstats will create it for you.

Using MLStats with MySQL

You are required to have MySQL installed and running in a computer. Please, refer to the manual of your distribution (if you are using Linux) or MySQL (if you are running other operating system) to install it, checking the database is running, and handling the database.

The MySQL backend requires the database already exists. Use the following command to create the database. The tables will be automatically created when mlstats runs.

mysql> create database mlstats;

Assuming you have a MySQL database running on localhost, you might run mlstats with these commonly used options (replace the text in ALL CAPS with your database username, database password and mailing list URL):

$ mlstats --db-engine=mysql --db-user=USERNAME --db-password=PASS http://URL-OF-YOUR-LIST

MySQL Tweaks

You may want to increase your max_allowed_packet: 1 or 16 MB may be too low (depends on your mailinglist). It has been reported that 50 MB might be a good value. To set this at runtime, use SET GLOBAL max_allowed_packet=16*1024*1024; on the mysql prompt.

Using MLStats with Postgres

The postgres backend requires the database already exists. The creation of tables must be done manually. There is a SQL script with the schema in db/data_model_pg.sql that can be used for this purpose.

Assuming you have a PostgreSQL database running on localhost, you might run mlstats with these commonly used options (replace the text in ALL CAPS with your database username, database password and mailing list URL):

$ mlstats --db-engine=postgres --db-user=USERNAME --db-password=PASS http://URLOFYOURLIST

Other MLStats Options

If you have a different configuration or need more options, more detailed information about the options, can be learnt by running mlstats --help.

Analysis

Analysis of mlstats data is completed by writing database queries. mlstats does the hard work of parsing the mailing list archives and storing all of this data into a database that can be used to extract meaningful data about a mailing list. Because what is meaningful varies by project, the flexibility of being able to write any query is a necessity.

While this does require a bit of knowledge about database queries, there are a few resources to help you get started.

  • Use the Database Schema wiki page to learn more about the database structure. This will help you write your queries, but it also gives you a comprehensive list of everything that can be found in the database and retrieved in your queries.
  • Because we don't want you to start from zero, use the Queries wiki page to find some commonly used queries and examples. If you have some interesting examples, please add them to the wiki page.

Improving MailingListStats

Source code, wiki and submission of bug reports are accessible in GitHub.

If you want to receive updates about new versions, and keep in touch with the development team, consider subscribing to the MetricsGrimoire mailing list. It is a very low traffic list, usually with less than one message per day.

Contributing

When making contributions, please follow the PEP8 specification. To check your code follows the specification, use a tool like pep8 or flake8.

When adding new features, add tests for the new feature or fix, and check that the existing tests pass. Tests live in pymlstats/tests and you can run them with:

$ python -m unittest discover

Please, also consider to add tests for the current features available.
