# Second Check-In

Hi everyone and may the odds ever in your favor, especially during this
tough time!

## What did I do last week?

Not as much I wished, apparently (-:

* Finalizing {{pip 8411 "the refactoring patch"}}
  of `operations.prepare.prepare_linked_requirement`
* {{pip 8423 "Nitpicking some logging calls"}}.  This (as well as the next one)
  was to fill up the time my brain not being as productive as I want it to XD
* {{pip 8423 "Beginning to migrate"}} from `%`- to `{}`-style logging.
  The amount of tests failing due to this was way beyond my imagination,
  but I got functional tests for `pip install` and unit tests passing now!
* {{pip 8442 "Mocking up a working partial wheel download during
  dependency resolution"}} for [the new resolver][].

## Did I get stuck anywhere?

Yes, of course!  {{pip 8320 "Parallel maps"}} are still stalling
as well as other small PRs listed above.  The failure related to
`logging` are still making me pulling my hair out and the proof of
concept for partial wheel downloading is too ugly even for a PoC.
I imagine that I will have a lot of clean up to do this week (yay!).

## What is coming up next?

I'm trying get the multi-{threading,processing} facilities merged ASAP
to start rolling it out in practice.  The first thing popping out of my
head is to get back {{pip 7962 "the multi-threaded"}} `pip list -o`.

The other experimental improvement (this phrase does not sound right!)
I would like to get done is the partial wheel download.  It would be
really nice if I can get both included as `unstable-feature`'s
in {{pip 7628#issuecomment-636319539 "the upcoming beta release of pip 20.2"}}.
