Teach Git to provide a way for users to enable/disable bitmap lookup table extension by providing a config option named 'writeBitmapLookupTable'. Default is false. Also add test to verify writting of lookup table.

# We want to create a situation where the shallow, grafted
|
|
# view of reachability does not match reality in a way that
|
|
# might cause us to send insufficient objects.
|
|
#
|
|
# We do this with a history that repeats a state, like:
|
|
#
|
|
# A -- B -- C
|
|
# file=1 file=2 file=1
|
|
#
|
|
# and then create a shallow clone to the second commit, B.
|
|
# In a non-shallow clone, that would mean we already have
|
|
# the tree for A. But in a shallow one, we've grafted away
|
|
# A, and fetching A to B requires that the other side send
|
|
# us the tree for file=1.
