Bugzilla-ETL 0.3.13353

Mozilla Bugzilla Bug Version ETL

Python version of Metric’s Bugzilla ETL (https://github.com/mozilla-metrics/bugzilla_etl)

Motivation and Details

https://wiki.mozilla.org/Auto-tools/Projects/PublicES

Requirements

• PyPy 2.1.0 using Python 2.7 (cPython is way too slow)

• A MySQL/Maria database with Mozilla’s Bugzilla schema (old public version can be found here)

• A timezone database (instructions)

• An ElasticSearch (v 0.20.5) cluster to hold the bug version documents

Installation

PyPy and SetupTools are required. If you are installing on Windows please follow instructions to get these installed. When done, installation is easy:

pip install Bugzilla-ETL

Setup

You must prepare a settings.json file to reference the resources, and it’s filename must be provided as an argument in the command line. Examples of settings files can be found in resources/settings

Bugzilla-ETL keeps local run state in the form of two files: first_run_time and last_run_time. These are both parameters in the ``settings.json``` file.

• first_run_time is written only if it does not exist, and triggers a full ETL refresh. Delete this file if you want to create a new ES index and start ETL from the beginning.

• last_run_time is recorded whenever there has been a successful ETL. This file will not exist until the initial full ETL has completed successfully. Deleteing this file should have no net effect, other than making the program work harder then it should.

Running bz_etl.py

Asuming your settings.json file is in ~/Bugzilla_ETL:

cd ~/Bugzilla_ETL
bzetl --settings=settings.json

Use --help for more options, and see example command line script

Got it working?

The initial ETL will take over two hours. If you want something quicker to confirm your configuration is correct, use --reset --quick arguments on the command line. This will limit ETL to the first 1000, and last 1000 bugs.

bzetl --settings=settings.json --reset --quick

Developer Installation

If you plan to help improve this software, or if you enjoy working from source, you can clone from Github:

git clone https://github.com/klahnakoski/Bugzilla-ETL.git

Install requirements:

pip install -e

It is best you install on Linux, but if you do install on Windows you can find further Windows-specific Python installation instructions at one of my other projects: https://github.com/klahnakoski/pyLibrary/blob/master/README.md

Running Tests

The Git clone will include test code. You can run those tests, but you must…

• Have MySQL installed (no Bugzilla schema required)

• Have timezone database installed (instructions)

• A complete test_settings.json file to point to the resources (example)

• Use pypy for 4x the speed: pypy .\tests\test_etl.py --settings=test_settings.json

More on ElasticSearch

If you are new to ElasticSearch, I recommend using ElasticSearch Head for getting cluster status, current schema definitions, viewing individual records, and more. Clone it off of GitHub, and open the index.html file from in your browser. Here are some alternate instructions.
