Hi all, |
| 2 |
|
| 3 |
Quick summary: Improve the performance of the Gentoo Linux mirrors by |
| 4 |
reducing the overall bandwidth load, allowing people to fetch binary |
| 5 |
patches from the mirrors, instead of the full source tarballs, when |
| 6 |
updating some package. This project is partially based on GLEP 25. |
| 7 |
|
| 8 |
I'm done with the tasks proposed to this project. |

|

A portage patch to add support for this is in the gentoo-portage-dev |
| 11 |
mailing list and was already changed twice. This feature will be |
| 12 |
present in a next Portage release, probably. The patch comes with some |
| 13 |
changes to the man pages, in order to document the usage of the |
| 14 |
feature. This implementation is almost transparent to the end users, |
| 15 |
then they just need to know about how to setup the configuration |
| 16 |
variable properly, and they are done. |
| 17 |
|
| 18 |
The patcher tools are working fine. I have more than 18k deltas cutted |
| 19 |
in vulture at this point. This number will increase a lot when we get |
| 20 |
deltas for the full tree. I'm not doing heavy tests for now because |
| 21 |
vulture is having some issues and rebooting a bit often due to unknown |
| 22 |
reason. |
| 23 |
|
| 24 |
This project also contributed a patch to diffball, adding XZ support |
| 25 |
to it. The patch is merged upstream and released in diffball-1.0.1. I |
| 26 |
also got commit access to the git repo of the project. Thanks |

The set of tools created for this project (app-portage/distpatch) are |
| 30 |
in the version 0.1.1 and available on gentoo tree (gentoo-x86). |
| 31 |
|
| 32 |
I also tried to create a video, demonstrating the usage of this |
| 33 |
feature. This was my first screencast and have some problems, but it |
| 34 |
does his work. |

I'm not announcing this on @-dev or @-user yet because, as planned on |
| 39 |
the proposal, this project isn't done by the end of gsoc. I'll still |
| 40 |
have to work with Robin and the infra team to get this thing deployed |
| 41 |
to the end users, and the patch isn't merged in portage yet. The |
| 42 |
announcement will comes as soon as possible. |
