[PATCH 13/20] unpack-trees: allow sparse directories

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Derrick Stolee <dstolee@xxxxxxxxxxxxx>

The index_pos_by_traverse_info() currently throws a BUG() when a
directory entry exists exactly in the index. We need to consider that it
is possible to have a directory in a sparse index as long as that entry
is itself marked with the skip-worktree bit.

The negation of the 'pos' variable must be conditioned to only when it
starts as negative. This is identical behavior as before when the index
is full.
