One project I have been thinking of is a grab-bag of bitmap-related
tasks. Some ideas for general improvements are:
- Designing a new .bitmap format (perhaps using the new chunkfile
API?) to allow us to add optional data to it in the future, like any
information we might need for a stable object order.
- Experimenting with replacing EWAH with different bitmap compression
algorithms to see if we can increase read performance and/or
decrease file size.
- Tidy up and take measurements from my RFC patch(es) to add an
extension which indicates which commits have bitmaps, and at what
position. These were discussed beginning at:
https://lore.kernel.org/git/YNuiM8TR5evSeNsN@nand.local/
(but they seem to help most when there isn't too much traversal
required between the ref tips and the bitmapped commits).
- Rethinking bitmap selection to be more robust against repositories
which have "spikey" ref tips and for which follow-on traversal is
expensive.
These are all fairly open-ended, and so may not make a good Outreachy
project. But I would be in favor of having more people familiar with and
interested in reachability bitmaps.
I'll think of some others, too.
Thanks,
Taylor
