Jonathan Tan	8708ca09a6	fetch-object: unify fetch_object[s] functions There are fetch_object() and fetch_objects() helpers in fetch-object.h; as the latter takes "struct oid_array", the former cannot be made into a thin wrapper around the latter without an extra allocation and set-up cost. Update fetch_objects() to take an array of "struct object_id" and number of elements in it as separate parameters, remove fetch_object(), and adjust all existing callers of these functions to use the new fetch_objects().

Jonathan Tan	c0c578b33c	unpack-trees: batch fetching of missing blobs When running checkout, first prefetch all blobs that are to be updated but are missing. This means that only one pack is downloaded during such operations, instead of one per missing blob. This operates only on the blob level - if a repository has a missing tree, they are still fetched one at a time. This does not use the delayed checkout mechanism introduced in commit `2841e8f` ("convert: add "status=delayed" to filter process protocol", 2017-06-30) due to significant conceptual differences - in particular, for partial clones, we already know what needs to be fetched based on the contents of the local repo alone, whereas for status=delayed, it is the filter process that tells us what needs to be checked in the end.

Jonathan Tan	88e2f9ed8e	introduce fetch-object: fetch one promisor object Introduce fetch-object, providing the ability to fetch one object from a promisor remote. This uses fetch-pack. To do this, the transport mechanism has been updated with 2 flags, "from-promisor" to indicate that the resulting pack comes from a promisor remote (and thus should be annotated as such by index-pack), and "no-dependents" to indicate that only the objects themselves need to be fetched (but fetching additional objects is nevertheless safe). Whenever "no-dependents" is used, fetch-pack will refrain from using any object flags, because it is most likely invoked as part of a dynamic object fetch by another Git command (which may itself use object flags). An alternative to this is to leave fetch-pack alone, and instead update the allocation of flags so that fetch-pack's flags never overlap with any others, but this will end up shrinking the number of flags available to nearly every other Git command (that is, every Git command that accesses objects), so the approach in this commit was used instead. This will be tested in a subsequent commit. Signed-off-by: Jonathan Tan <jonathantanmy@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>	7 years ago
