[gentoo-soc] libebuild - weekly report #1

[Denis Romanchuk]

Hi there,

My progress so far:
- got familiar with python/C api, writing C extensions for python
- added cpv (category/package/version) ebuild parsing

Plan for next week:
- add atom parsing functionality
- add python unittests for cpv and atom parsing

[Denis Romanchuk]

Hello,

My second week progress:
Added atom parsing functionality, including  python bindings and unittests.

Plan for next week:
Add boolean restrictions, support for combining arbitrary collections of 
boolean restrictions. Add bindings and tests for restrictions. Expand existing 
test, add atom comparison.

Hello,

My third week progress:
This week I've spent some time exploring pkgcore,portage,portage-utils code so 
to get the vision of what functionality is needed to implement restriction and 
other subsystem. Also added rich comparison methods for cpv and atom parsing, 
versions comparison, some tests.

Plan for next week:
Add atoms intersection, various eapi support for parsing, rewrite another 
pkgcore PythonC extensions, particularly depset, use conditionals, as it works 
hand in hand with restrictions.

Hello,

My forth week progress:
Added atom intersects/compare, atom eapi constraints. Investigated different 
approaches of dependencies handling and merge plan composition in 
pkgcore,portage,paludis.

Plan for next week:
Should have package protocol with metadata as restrictions subsystem rely on 
it, and depset parsing/evaluation in turn is reliant on restrictions.

[Denis Romanchuk]

Hello,

My fifth week progress:
Added libebuild version extension, cpv/atom error codes, handling. Integrated 
cpv extension into pkgcore, almost integrated atom extension (some issues 
arose).

Plan for next week:
Finish atom integration. Work on restriction/package protocol 
implementation/improvement, write cython/C extensions, think on design.

[Denis Romanchuk]

Hello,

My seventh week progress:
Integrated cpv/atom/version extensions into pkgcore,
Pass pkgcore tests, make py2_3 compatible.

Plan for next week:
Work on restrictions and other pkgcore/libebuild improvements, investigate 
performance critical places, memory usage.
Possibly write other cpython extensions.

[Denis Romanchuk]

Hello,

My eight week progress:
This week I've mostly spent to get more familiar with some of the pkgcore 
subsystems implementation and examine following tasks.

Plan for next week:
Work on restrictions and other pkgcore/libebuild improvements,
Take out conditional restrictions into separate restrictions 
module(conditional) and come up with new design(remove recursive use 
conditional evaluation in particular) which will help to reduce memory 
consumption in case of a lot of conditional use dependencies appears and also 
should simplify other code paths.

[Denis Romanchuk]

Hello,

My tenth week progress:
Making a couple of pkgcore bugfix and enhancement related PRs
https://github.com/pkgcore/pkgcore/pulls

My plan for the next week:
Pick some new issues from pkgcore list, finish opened PRs considering related 
discussions and reviews. In particular, complete restriction related PR which 
may trigger more refactoring/improvement of restriction module. Think about 
what other modules might be added to libebuild.
