If the project idea is related to Hariom or my GSoC project, I think I can
provide a lot of help. :) I can help them as a mentor.
This may be a place to promote my patches: See [1][2][3].
It can provide some extra atoms for git cat-file --batch | --batch-check,
like %(tree), %(author), %(tagger) etc. Although some performance
optimizations have been made, It still has small performance gap.
If the community still expects git cat-file --batch to reuse the logic
of ref-filter,
I expect it to get the attention of reviewers.
The solutions I can think of to further optimize performance are:
1. Delay the evaluation of some ref-filter intermediate data.
2. Let ref-filter code reentrant and can be called in multi-threaded to take
advantage of multi-core.
These ideas may be very difficult to implement now.
