[gentoo-soc] Distfile patching support - Weekly report #1

[Rafael Martins]

Hi all,

some of you guys may remember me from last year, when I was working
with g-octave, or from my recent work as a Gentoo developer. This year
I'm working in the "Distfile patching support" project. You can know
more about it reading my proposal [1].

This year I decided to stop posting weekly reports at my blog [2],
because this kind of post is usually uninteresting and boring for most
readers. All my reports will be here.


== Progress ==

- XZ support for diffball is done. Brian will likely merge it and
release a new version soon. :)
- Lineage identification algorithm is done and works fine when
creating single hop sequential patches. Would need some minor
improvements.
- Script to create deltas for all available versions of a package
(distdiffer) is almost done. I still need to implement the manifest
generation. There's an example of the script running on verbose mode
[3]. It works for more than 1 package, but can't generate the list of
packages by himself. It needs to get the list of packages from the
command-line arguments, from a file or from stdin.
- Basic class to reconstruct the distfiles from deltas was created,
mainly to be used in the validation of the generated deltas, but will
be the base for the reconstructor script (distpatcher).

The scripts and helper classes/modules are being written in Python,
and a Git repository is available [4] (temporary, will be moved to
gentoo-infra soon).

That's all for now.

Regards.
