Subject: [PATCH 1/8] http: use --stdin when getting dumb HTTP pack
Date: Fri, 29 May 2020 15:30:13 -0700 [thread overview]
Message-ID: <4d17d560b87746acfd62ff785cc22c09600d4e65.1590789428.git.jonathantanmy@google.com> (raw)
In-Reply-To: <cover.1590789428.git.jonathantanmy@google.com>
When Git fetches a pack using dumb HTTP, it reuses the server's name for
the packfile (which incorporates a hash), which is different from the
behavior of fetch-pack and receive-pack.
A subsequent patch will allow downloading packs over HTTP(S) as part of
a fetch. These downloads will not necessarily be from a Git repository,
and thus may not have a hash as part of its name.
Thus, teach http to pass --stdin to index-pack, so that we have no
reliance on the server's name for the packfile.
