illustris / manual_bisect.py
Created May 3, 2018 13:14
A short script I wrote to manually bisect a list of commits. Git bisect doesn;t play well with repo or submodules
def binsearch(commits):
if len(commits) == 1:
print commits[0]
else:
print commits[(len(commits)-1)/2]
answer = ""
while answer not in ["y", "n"]:
answer = raw_input("Working? [Y/N] ").lower()
if answer == "n":
binsearch(commits[(len(commits)+1)/2 : ])
