Subject: [RFC PATCH 0/3] Partial clone: promised blobs (formerly "missing blobs")
Date: Tue, 11 Jul 2017 12:48:29 -0700	[thread overview]
Message-ID: <cover.1499800530.git.jonathantanmy@google.com> (raw)

These patches are part of a set of patches implementing partial clone,
as you can see here:

https://github.com/jonathantanmy/git/tree/partialclone

In that branch, clone with batch checkout works, as you can see in the
README. The code and tests are generally done, but some patches are
still missing documentation and commit messages.

These 3 patches implement the foundational concept - formerly known as
"missing blobs" in the "missing blob manifest", I decided to call them
"promised blobs". The repo knows their object names and sizes. It also
does not have the blobs themselves, but can be configured to know how to
fetch them.

An older version of these patches was sent as a single demonstration
patch in versions 1 to 3 of [1]. In there, Junio suggested that I have
only one file containing missing blob information. I have made that
suggested change in this version.

One thing remaining is to add a repository extension [2] so that older
versions of Git fail immediately instead of trying to read missing
blobs, but I thought I'd send these first in order to get some initial
feedback.
