[gentoo-soc] pomu: weekly report for week #2

[Mykyta Holubakha <hilobakho@gmail.com>]

This is the weekly report for the week o 05-11.06.

Progress made this week:
1) created the framework for package source modules and all the
necessary modules;
2) created the abstraction for packages, with the ability to create
them from directory trees, or file lists;
3) reworked the cli design, significantly simplifying the codebase;
4) added install, fetch, and uninstall commands.

This basically means, that with addition of the first package module
this week, there will be a working tool already (implementing the core
of the initial idea).

Plans for the next week:
1) implement the first package source module (adding packages from
portage repos);
2) properly design metadata storage format (and implement storing it);
3) decide on commit message generation;
4) manifest generation.

This weeks commits:
- Repository logic and import fixes
- Cli fixes
- Major active repo refactoring
  made pomu_active_repo cache its first retval (and unwrap() it immediately)
  this allows the code to assume it can always get the active repository
- Proper global error handling
- cli: added fetch, install, uninstall commands
  pomu repo detection refactoring
- Numerous fixes all over the tree
  Added dispatcher and repository package (un)installation tests
- Actually return Result.Ok when a package is found
- Initial progress on dispatch testing
  Fixed an error in the dispatcher
- Hook up sources, repo and dispatcher
  Implement initial package recording, uninstalling
- Fix multiple issues with packages and repositories
- Process on package impl
- Add repository and package abstractions
