From 2b713c272cd8f9dc70ad746e8ba01a93d8baa023 Mon Sep 17 00:00:00 2001 From: Jonathan Tan Date: Mon, 17 Aug 2020 21:01:32 -0700 Subject: fetch: allow refspecs specified through stdin In a subsequent patch, partial clones will be taught to fetch missing objects using a "git fetch" subprocess. Because the number of objects fetched may be too numerous to fit on the command line, teach "fetch" to accept refspecs passed through stdin.

Currently "fetch" handles this by first reading .gitmodules, then reading .git/config (allowing it to overwrite existing values), then reading the command line (allowing it to overwrite existing values). Notice that we can avoid reading .gitmodules if .git/config and/or the command line already provides us with what we need. In addition, if recurse_submodules is found to be "no", we do not need the value of submodule_fetch_jobs_config. Avoiding reading .gitmodules is especially important when we use "git fetch" to perform lazy fetches in a partial clone because the .gitmodules file itself might need to be lazy fetched (and otherwise causing an infinite loop). In light of all this, avoid reading .gitmodules until necessary. When reading it, we may only need one of the two parameters it provides, so teach fetch_config_from_gitmodules() to support NULL arguments. With this patch, users (including Git itself when invoking "git fetch" to lazy-fetch) will be able to guarantee avoiding reading .gitmodules by passing --recurse-submodules=no.

Iterating over refs causes the targets of those refs to be checked for existence. Avoiding this is especially important when we use "git fetch" to perform lazy fetches in a partial clone because a target of such a ref may need to be itself lazy-fetched (and otherwise causing an infinite loop). Therefore, avoid populating "existing_refs" until necessary. With this patch, because Git lazy-fetches objects by literal hashes (to be done in a subsequent commit), it will then be able to guarantee avoiding reading targets of refs.
