Subject: [PATCH] sha1_file: restore OBJECT_INFO_QUICK functionality
Date: Tue, 13 Mar 2018 08:30:29 -0700
Message-ID: <20180313153029.257296-1-jonathantanmy@google.com> (raw)
In-Reply-To: <xmqqr2ouwgsd.fsf@gitster-ct.c.googlers.com>

Support for the OBJECT_INFO_QUICK flag in sha1_object_info_extended()
was added in commit dfdd4afcf9 ("sha1_file: teach
sha1_object_info_extended more flags", 2017-06-26) in order to support
commit e83e71c5e1 ("sha1_file: refactor has_sha1_file_with_flags",
2017-06-26), but it was inadvertently removed in commit 8b4c0103a9
("sha1_file: support lazily fetching missing objects", 2017-12-08).

Restore this functionality.

They are, but they are not supposed to be. Here is a patch correcting
that.
