fs-sparse 0.1

A wrapper for sparse file detection

# fs-sparse: a wrapper to check sparse file

## Generate test files

Using scripts provided in test/create_test_file.sh, it will generate two files:

• normal.dat with no holes;

• sparse.dat with holes.

## Usage

The interface exposes three functions, see example below. Note that if a file has no holes, the # of extents (or tuple) will be 1.

In [1]: import sparse

In [2]: sparse.get_extents(“test/sparse.dat”) Out[2]: [(0, 8192), (28672, 36864), (40960, 45056)]

In [3]: sparse.get_extents(“test/normal.dat”) Out[3]: [(0, 8192)]

In [4]: sparse.is_sparse(“test/normal.dat”) Out[4]: False
