CAOS keeps incoming uploads as Git packfiles. The server reads them through
gix, which fixes its pack capacity when it opens the store, starting at 32 for a small repository. With automatic repacking disabled, enough uploads can exhaust those slots even though the objects are still on disk.This PR reserves 32,767 slots, the maximum
gixsupports. The server warns near the limit and refuses to start when it is reached. We’ll still need to consolidate old packfiles before reaching that limit.Commit validation has a related problem: its temporary repository uses the server’s object store as a Git alternate. Writing the candidate commit after attaching that alternate can make
gixtry to load all the server’s packs into another small slot table. Write the candidate first, then attach the alternate for Git to validate it.
