[gentoo-soc] Distfile patching support - Weekly report #4

[Rafael Martins]

Hi all

Quick summary: Improve the performance of the Gentoo Linux mirrors by
reducing the overall bandwidth load, allowing people to fetch binary
patches from the mirrors, instead of the full source tarballs, when
updating some package. This project is partially based on GLEP 25.

The project is ahead of schedule.

== Progress ==

This week I did the script to generate deltas for all the available
packages in gentoo-x86 tree, as needed. Actually, I added a --all
option to distdiffer.py. When I started writing the script I realized
that isn't worth to create another script, and just patched
distdiffer. It's working ok in my quick tests. I'm still improving the
error hanfling and planning how is the best way to deal with malformed
deltas by default.

== Next steps ==

Next week I'll finally do the big run I was planning for last week.
This should take really long as we have more than 14k packages in tree
IIRC. I'll be monitoring the test and improving the error handling as
needed.

Best regards,
