seedcheck: keep deltas on a dropped seed readable; make a drop atomic
Review follow-ups to the seed drop. A delta that arrives on a seed already dropped could never be read: it was stored on a content-less row that is never filled or asked for. It is now not stored as a delta but left a phantom and asked for again in full, on a pull, a clone's phantom pull and a push to an origin. A seed that arrives in full after deltas built on it is stored just long enough to check those deltas, judge them and rewrite them as full text, and then dropped. seedcheck.Drop runs in a savepoint (or a transaction of its own on a pool), so a failure partway, which the after-dephantomize cascade logs and commits past, leaves the seed and its dependents as they were. An origin answering a push no longer asks for a refused seed's phantom, and a clone asking for what it left missing no longer counts one. fossil 2.28's rebuild re-adds every size<0 row to the phantom table and deletes the store-local seedrefused and seedpending tables; the CHANGELOG notes this and the one-time drop of refused seeds that older stores kept. The client now adds to a reply's new-phantom count rather than replacing it, so a phantom made while receiving a file continues the exchange. leaf check-in: 41c092205e user: [email protected] tags: fix/seed-delta-drop, main, trunk | |

seedcheck: drop a seed completed as a delta in a later round
A horizon seed stored as a delta whose base arrived only in a later round (pull, clone) or a later request (origin push) was refused by its hash but kept in the store, and a pull or clone counted the delta as received on arrival, before it could be judged (draft-fossil-horizon-00 §5.2.3, HZ-5.2-14). On a seed verdict seedcheck now rewrites each delta built on the seed as full text, then empties the seed's row: size -1, no content, no delta link, and kept out of the phantom table so no request asks for it. The rid stays held for anything a receive pass tracks by it, and the refused hash is still recorded in store-local state. A pull or clone counts a delta it could not read on arrival only at the end of the exchange, once readable and not dropped. A round still treats it as progress. The receive pass treats a row without content as no basis even when its cache holds the old bytes, and the push handler's same-request seed check consults the refused hash, since the dropped row no longer reads. HZ-5.2-14 is now covered. check-in: 917bcc9830 user: [email protected] tags: fix/seed-delta-drop, main, trunk | |
