Traits

HeaderTypeCache

Memo of pack offset -> resolved header (end-of-chain type, result size) for the cat-file --batch-check header fast path.

PackDeltaCache

A cache of objects already decoded from one specific pack, keyed by the in-pack byte offset at which each object’s entry begins.

PackIndexByteSource

Functions

pack_order_index_positions

The .rev table for a pack: index positions (the rank of each object in the oid-sorted .idx) listed in pack order (ascending pack offset), as upstream write_rev_file lays them out. Accepts entries in any order; the result feeds PackReverseIndex::write.

read_object_at_arc

Decode the single object stored at byte offset within pack_bytes, reading only that object and its delta-base chain instead of parsing the whole pack.

read_object_at_with_cache_and_ofs_base_arc

Like read_object_at_with_cache_arc, but lets an object-database caller recover an ofs-delta base from another storage copy when the in-pack base offset cannot be decoded. Direct pack verification should keep using the strict APIs; this hook mirrors normal object lookup, where a corrupt packed copy does not hide a good loose or redundant packed copy.

read_object_at_with_cache_arc

Like read_object_at_arc, but reuses already-decoded objects from cache (keyed by in-pack offset) and records every object it decodes.

read_object_at_with_ofs_base_arc

Like read_object_at_with_cache_and_ofs_base_arc, without an offset-cache.

read_object_header_at

The object type and final (inflated) size of the entry at offset, without materializing the object body — git’s cat-file --batch-check fast path.

read_object_header_at_with_cache

Like read_object_header_at but threads a caller-owned HeaderTypeCache through the read so (a) the ofs-delta chain’s end-of-chain type is resolved at most once per chain and (b) a repeated lookup of the same offset returns from the memo without re-inflating (sley#26). The cache is keyed by in-pack offset, so it must be scoped to a single pack’s bytes by the caller.

write_bitmap

Convenience wrapper that builds a .bitmap file in one call.
