[Soc-2016-dev] Weekly Report #04, Python Package Manager

[Peter D. Cassetta]

Hi all,

During the fourth week of GSoC, I've been working towards my goal for 
Jun 6 - Jun 17 as stated in my proposal: "By the 17th, should have a 
functional prototype allowing at least to check for updates and update 
an add-on."

I did not get as far as I planned this week; the add-on can successfully 
download and parse the index.json file, but does not yet allow to 
download/update an add-on. I would estimate I am a couple days behind 
schedule.

As the next two weeks' goal is a little more lenient, and very closely 
related to this week's work, I'll aim to finish up a functional first 
version by Tuesday/Wednesday, and move on to those goals afterward.

By chance, I discovered that gitweb is already running on blender.org 
[1], something I hadn't realized previously. Gitweb would make it 
trivial to access add-ons in my blender-package-manager-addon repo from 
within Blender, as gitweb provides access to raw files natively. Since 
it also fits with Ton's request that nothing new be installed on 
blender.org, this seems to me the optimal way to proceed.

Before I go ahead with this plan, I'd just like confirmation on 
something. I remember with addons_contrib, back when SVN was used, 
binary files were strongly avoided. With this in mind, I would like to 
get a go-ahead (from someone like Ton) before I commit any binary files 
(zipped add-ons) to the repository.

Earlier today I committed the in-progress first version of my package 
manager add-on [2], along with the index.json file and the functional 
(but not yet pretty) .py script which generates it. Any feedback on 
coding style, best practice, etc. is welcomed. :-)

As mentioned earlier, next week I'll be finishing up basic 
functionality, then work towards my goal for Jun 20 - Jul 1: "Enable 
rollback and the option to prevent deleting original add-on after 
update, restoring the original add-on if an update fails".

Best regards,
Peter Cassetta
