# VDS test files from libhdf5

Copied unchanged from the HDF Group's HDF5 repository,
`tools/test/testfiles/vds/` (the h5dump/h5ls VDS test data). HDF5 is
distributed under a BSD-style license (see `COPYING` in the HDF5 source).

| File | What it exercises |
|---|---|
| `vds-eiger.h5` + `f-0.h5`, `f-3.h5` | printf-style source name `f-%b.h5`; `f-3.h5` lies past the first missing source and must be ignored (extent 5, not 20) |
| `4_vds.h5` + `4_0.h5`..`4_2.h5` | printf-style `4_%b.h5` with version-2 (1.10 format) hyperslab selections |
| `vds-percival-unlim-maxmin.h5` + `a.h5`..`d.h5` | four interleaved unlimited mappings whose sources have different lengths |

Used by `crates/clawhdf5/tests/vds_interop.rs::vds_libhdf5_test_files`,
which compares our reads with h5py's.
