From 01f9ec64c8a82a05ba7e5a17b292ede037a469ea Mon Sep 17 00:00:00 2001 From: Masaya Suzuki Date: Sat, 29 Dec 2018 13:19:14 -0800 Subject: Use packet_reader instead of packet_read_line By using and sharing a packet_reader while handling a Git pack protocol request, the same reader option is used throughout the code. This makes it easy to set a reader option to the request parsing code.
