Git Object Storage Quiz

Review

1. What does `git count-objects` primarily report?

   `git count-objects` reports loose-object counts and storage consumption, with verbose fields for packed objects and related storage states.
2. Which field reports objects stored in packfiles?

   The verbose report uses `in-pack` for the number of objects in packfiles.
3. What does `-H` change for `git count-objects`?

   `-H`/`--human-readable` changes size reporting to human-readable units.
4. Why is `git repack -ad` used carefully in this lesson?

   Repacking changes the physical object-storage layout and `-d` removes redundant old packs after repacking.
5. What file does `git verify-pack` take as its normal input?

   The command takes pack index files ending in `.idx` and verifies each index with its corresponding pack.
6. What does `git verify-pack -s` do?

   `-s`/`--stat-only` reports the delta-chain histogram without verifying the pack contents.
7. Which command is the appropriate boundary for repository object connectivity and validity?

   `git fsck` is the repository-level connectivity and validity check; storage-inspection commands answer different questions.
8. After repacking a small repository, which observation is expected?

   Repacking changes physical storage; it does not rewrite the repository’s refs or commit IDs.
