Subject: [RFC PATCH 0/7] Lazy fetch with subprocess
Date: Tue, 4 Aug 2020 18:20:43 -0700 [thread overview]
Message-ID: <cover.1596590295.git.jonathantanmy@google.com> (raw)
In-Reply-To: <20200724223844.2723397-1-jonathantanmy@google.com>
Here's some code that performs the lazy fetch in a subprocess. It was
more involved than I thought it would be, but here it is.
My main concern is the user-facing interface for the null fetch
negotiator. It not only does not negotiate at all but affects the
everything_local() check, so I wonder if it should be exposed
differently. More information is in the commit message for the 2nd
patch.
I know that the following still needs to be done, but I thought I'd send
out the patches for early feedback first since the main design and code
is already done:
- Commit messages
- User-facing documentation
- A way to prevent a promisor-remote fetch from invoking another
promisor-remote fetch (use a file as a lock?)
- Remove no_dependents code (fetch-pack, transport)
Jonathan Tan (7):
fetch-pack: allow NULL negotiator->add_tip
fetch-pack: allow NULL negotiator->known_common
negotiator/null: add null fetch negotiator
fetch: --stdin
fetch: submodule config
fetch: only populate existing_refs if needed
promisor-remote: use subprocess to fetch
