Subject: [PATCH v2 4/8] fetch: refactor the population of peer ref OIDs
Date: Wed, 13 Jun 2018 14:39:21 -0700	[thread overview]
Message-ID: <20180613213925.10560-5-bmwill@google.com> (raw)
In-Reply-To: <20180613213925.10560-1-bmwill@google.com>

Populate peer ref OIDs in get_ref_map instead of do_fetch. Besides
tightening scopes of variables in the code, this also prepares for
get_ref_map being able to be called multiple times within do_fetch.
