onemillion

Determine if a domain is in the Alexa or Cisco top one million domain list.

Documentation is available here: https://onemillion.readthedocs.io . There is a UI/API using this package available here: http://onemillion.hightower.space

Installation

The recommended means of installation is using pip:

pip install onemillion

Alternatively, you can install onemillion as follows:

git clone https://github.com/fhightower/onemillion.git && cd onemillion;
python setup.py install --user;

Usage

When using the default settings, the following steps will be taken when an instance of onemillion is initialized and the domain_in_million function called:

1. Check to see if the domain lists have been updated today.

2a. If they have been updated today, look for the given domain in the lists and stop.

2b. If the lists have not been updated today, make a HEAD request and check the current etag against the previous etag (stored locally) to see if the lists have been updated.

3a. If the etags are the same (meaning the lists have not been updated), look for the given domain in the lists and stop.

3b. If the etags are different (meaning the lists have been updated), make a request for the lists, unzip them, and save them in the default cache location (~/.onemillion).

4. Now that the lists are updated, search for the given domain in the lists.

Default Usage ~ Hello World!

Via Python

The default usage of onemillion is as follows:

import onemillion

o = onemillion.OneMillion()
o.domain_in_million("google.com")  # 1
o.domain_in_million("gaagle.com")  # None

Using the method described above, the alexa and cisco top one million domain lists as well as a bit of metadata will be stored in the home directory: ~/.onemillion.

Via Command Line

The default usage of onemillion via command line is as follows:

onemillion google.com

As as when using onemillion in a python script, the alexa and cisco top one million domain lists as well as a bit of metadata will be stored in the home directory: ~/.onemillion.

No Caching

Via Python

If you do not want to cache the domain lists, you can tell onemillion not cache anything by setting cache=False on initialization as demonstrated below:

import onemillion

# do not cache anything
o = onemillion.OneMillion(cache=False)
o.domain_in_million("google.com")  # 1
o.domain_in_million("gaagle.com")  # None

The code described above is fine if you are only making one or two calls or if storage space is a concern, but it is suggested that you cache the lists if feasible so as to limit traffic to the domain lists.

NOTE: currently, the 'No caching' configuration will throw an error. This will be updated and handled when issue #12 is fixed.

Via Command Line

Via command line, same principle as above:

onemillion google.com --no-cache

Custom Cache Location

Via Python

If you are caching the lists but want to cache them somewhere other than your home directory, you can specify a custom cache location by setting the cache_location parameter when initializing onemillion as demonstrated below:

import onemillion

# cache data to a specific path
o = onemillion.OneMillion(cache_location=<YOUR_PATH_HERE>)
o.domain_in_million("google.com")  # 1
o.domain_in_million("gaagle.com")  # None

This will cache the domain lists in the path you provide.

Via Command Line

Via command line, same principle as above:

onemillion google.com --cache_location ~/.cache/onemillion/

or

onemillion google.com -l ~/.cache/onemillion/

No Update

Via Python

If you have already run onemillion and have the domain lists cached, but do not want to keep updating them, you can specify update=False on initialization as demonstrated below:

import onemillion

# do not update cached content
o = onemillion.OneMillion(update=False)
o.domain_in_million("google.com")  # 1
o.domain_in_million("gaagle.com")  # None

Be aware that onemillion will, by default, check to see if it has already updated the domain lists today before making any requests. Thus, onemillion handles updating responsibly and intelligently by default and there are few cases in which this configuration (using update=False) is necessary. Nevertheless... it's there and you are welcome to use it.

Via Command Line

Via command line, same principle as above:

onemillion google.com --no-update
