From 47a02ff2ca821c52268197dd5fa46cd60a2e94bc Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Wed, 7 Mar 2012 17:54:15 +0700 Subject: streaming: make streaming-write-entry to be more reusable MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The static function in entry.c takes a cache entry and streams its blob contents to a file in the working tree. Refactor the logic to a new API function stream_blob_to_fd() that takes an object name and an open file descriptor, so that it can be reused by other callers.
