Google Code-in

Pywikibot is a Python-based framework to write bots for MediaWiki (more information).

Thanks to work in Google Code-in, Pywikibot now has a script called download_dump.py. It downloads a Wikimedia database dump from http://dumps.wikimedia.org/, and places the dump in a predictable directory for semi-automated use by other scripts and tests.

This script downloads big files, a progress bar or another indicator can be really useful.

You must avoid using external libraries for this. For reference, please read:

• https://github.com/wikimedia/pywikibot/blob/master/pywikibot/page.py#L2686-L2693

It would be even better if something like 105.2M/2.1G can be shown alongside the progress bar. (Not required)

You are expected to provide a patch in Wikimedia Gerrit. Documentation on Gerrit is available.
