Subject: [PATCH 03/23] refs.c: add a function to append a reflog entry to a fd
Date: Fri, 5 Dec 2014 00:08:15 +0100 [thread overview]
Message-ID: <1417734515-11812-4-git-send-email-mhagger@alum.mit.edu> (raw)
In-Reply-To: <1417734515-11812-1-git-send-email-mhagger@alum.mit.edu>
From: Ronnie Sahlberg <sahlberg@google.com>
Break out the code to create the string and writing it to the file
descriptor from log_ref_write and add it into a dedicated function
log_ref_write_fd. For now this is only used from log_ref_write,
but later on we will call this function from reflog transactions too,
which means that we will end up with only a single place,
where we write a reflog entry to a file instead of the current two
places (log_ref_write and builtin/reflog.c).
