[PATCH v3 11/26] grep: ensure full index

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

 



From: Derrick Stolee <dstolee@xxxxxxxxxxxxx>

Before iterating over all cache entries, ensure that a sparse index is
expanded to a full one so we do not miss blobs to scan. Later, this can
integrate more carefully with sparse indexes with proper testing.
