* Add `Commits` model: unique `git_commit_hash`, nullable author/committer/subject/message/`fetched_from_url` * Add `CommitParents` model: FKs to `commits.id`, `ord` with 0 = first parent, unique `(commit_id, ord)` * Add migration `0021_commits_and_commit_parents` (`commits`, `commit_parents` tables and indexes) * Join from `checkouts.git_commit_hash` without new checkout columns Signed-off-by: Alan Peixinho <alan.peixinho@profusion.mobi>
Dump commits and commit_parents in full so git ancestry survives restore. Signed-off-by: Alan Peixinho <alan.peixinho@profusion.mobi>
Add a SHA-only helper for commit author/parents so later sync can reuse parsing without duplicating git format handling. Signed-off-by: Felipe Bergamin <felipebergamin@profusion.mobi>
…nelci#2079) Fetch allowlisted trees into GIT_MIRROR_DIR and ingest the tip delta into commits / commit_parents (not checkout hashes). Probe filter support, keep kernel.org packs, split mirror vs ingest crons, and exclude stored tips with ^sha on rev-list stdin. Signed-off-by: Felipe Bergamin <felipebergamin@profusion.mobi>

TL;DR
Fill
commits/commit_parentsfrom git objects, not KCIDB. A persistent bare mirror atGIT_MIRROR_DIRfetches allowlisted trees; a second cron ingests the tip delta from that mirror (ancestor closure, notDISTINCT checkouts.git_commit_hash). Does not writecheckouts.git_commit_message.Closes #2109. Part of #2079. Schema #2089 and parse helper #2090 are still on this branch if they have not merged yet.
