[PATCH v3 23/26] revision: ensure full index

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

 



From: Derrick Stolee <dstolee@xxxxxxxxxxxxx>

Before iterating over all index entries, ensure that a sparse index is
expanded to a full index to avoid unexpected behavior. This case could
be integrated later by ensuring that we walk the tree in the
sparse-directory entry, but the current behavior is only expecting
blobs. Save this integration for later when it can be properly tested.
