From 3a3fc6b071f09970e7f79fb4f1a8f0013917371e Mon Sep 17 00:00:00 2001 From: Yu Ke Date: Wed, 19 Jan 2011 00:22:13 +0800 Subject: bb.fetch2: Add git unpack The git download method clones the git repository to the local machine. The unpack process can be optimised to be a local to local machine clone or a direct readtree operation to the destination using git.will clone git repo to local, so git unpack can be simplified to only checkouting the code to the work dir. For fullclone case, we also need to manually copy all the ref info, which is needed by the later do_kernel_checkout(). Rather than use hardlinks, we reference the repository using alternatives since the download directory may be on a different filesystem.
