[GSoC] Status update

[Shaoxuan Yuan]

Hi Git community,

Here is Shaoxuan Yuan. I'm this year's GSoC student for the project
"More Sparse Index Integration". My mentors Derrick and Victoria and I
are already in touch for a while on the Slack channel, and I'm writing
to let the community know that things are going well.

For the progress report, I'm going to do a weekly blog here [1].

As for now, I'm still working with my mentors to refactor mv.c for
sparse-checkout and sparse-index integration. This series is WIP here
[2].

[GSoC] Week 3 and week 4 status update

Summary of the week 3 and week 4

At this stage, the main focus is on making `git-sparse-checkout` work better
with `git-mv`. With the ongoing "from out-of-cone to in-cone" clearing
up, I'm also working to make the complementary "from in-cone to out-of-cone"
possible. Read the previous blogs on GSoC to get a better context.

In the meantime, some experiments towards integration with `sparse-index`
have also started, which are based on the latest work "from in-cone to
out-of-cone" boiling in my branch.

This week I'm working to ship a PATCH v5 [2] (please reference all the
code here) to address the issues raised in PATCH v4 [3].

The good news is, that PATCH v5 is being queued into the 'next' branch, 
which
means it could potentially be merged into 'master'. It marks that this stage
of work is almost done.

Thanks for the report!

(I think this is left over from earlier?)

In fact, the latest "What's Cooking" says this:

* sy/mv-out-of-cone (2022-07-01) 8 commits
  (merged to 'next' on 2022-07-08 at 654970fdb7)
 + mv: add check_dir_in_index() and solve general dir check issue
 + mv: use flags mode for update_mode
 + mv: check if <destination> exists in index to handle overwriting
 + mv: check if out-of-cone file exists in index with SKIP_WORKTREE bit
 + mv: decouple if/else-if checks using goto
 + mv: update sparsity after moving from out-of-cone to in-cone
 + t1092: mv directory from out-of-cone to in-cone
 + t7002: add tests for moving out-of-cone file/directory

 "git mv A B" in a sparsely populated working tree can be asked to
 move a path between directories that are "in cone" (i.e. expected
 to be materialized in the working tree) and "out of cone"
 (i.e. expected to be hidden).  The handling of such cases has been
 improved.

 Will merge to 'master'.
 source: <20220630023737.473690-1-shaoxuan.yuan02@gmail.com>

So, it is already in 'next' and will merge to 'master' soon. You
should expect those commits to be final (barring anything drastic
noticed during the cooking phase) so you can send your next set
of patches. Just make sure to point out in the cover letter that
they are based on sy/mv-out-of-cone. That branch is available in
the gitgitgadget/git repository so you can base a PR against it,
if you want.

[GSoC] Week 5 and week 6 status update

Summary of the two weeks

At this stage, the main focus is on making `git-sparse-checkout` work
better with `git-mv`. After getting the "from out-of-cone to in-cone"
series merged [2] into master, I'm working to make the complementary
"from in-cone to out-of-cone" [3] possible. It's now a [PATCH v1].
Read the previous blogs on GSoC to get a better context.

In the meantime, I'm also experimenting with `git-rm` to integrate with
`sparse-index`. `git-rm` turns out to be a slightly less complex command
in terms of its interaction with `sparse-checkout`, so working with it
at the same time gives me some insight into `sparse-index`, without
worrying too much about its compatibility with `sparse-checkout`.

Summary

In the past two weeks, besides keeping the work on `git-mv`, I was
also working on the sparse-index integration with `git-rm`. I shipped
one iteration of `git-mv` series and two iterations of `git-rm`
series. At the time of writing, `git-mv` is v2 and `git-rm` is also v2.

[GSoC] Week 9 status update

Hi Git community,

Summary

In week 9, I did two things:

1. Send out a v3 for `git mv` (from-in-to-out).
2. Explore `git grep` and try to integrate with sparse index.

Good news this week:

1. `rm` is in the `next` branch, hooray!

I found that a verbatim development log is both hard to write and read,
so I decided that I should only catch the interesting moments which may
be educational or amusing :)
