描述

I'm indexing several hundred repos, and a few of them are currently empty. This causes an error in hound's logs:

2016/11/28 18:08:09 Failed to git fetch /users/foo/hound/data/vcs-ce7a7ad7a7faafc79f1aaaf7df43a2f9da56539, see output below
fatal: Couldn't find remote ref master
Continuing...
2016/11/28 18:08:09 exit status 128

If I cd to the relevant directory:

$ git log
fatal: your current branch 'master' does not have any commits yet

研究方向
Investigate how hound handles git operations, likely in the 'git' package or similar. Look for where 'git fetch' is called and handle the case where the repository is empty (no commits). The error occurs when trying to fetch remote ref 'master' which doesn't exist. Modify the code to check if the repository is empty before fetching, or handle the error gracefully.
