[svn-r5524]

Purpose: Bug fix (#699), fix provided by a user, approved by Quincey Description: When a scalar dataspace was written to the file and then subsequently queried with the H5Sget_simple_extent_type function, type was reported H5S_SIMPLE instead of H5S_SCALAR. Solution: Applied a fix (see bug report 699) Platforms tested: Solaris 2.7 and Linux 2.2.18

The dataset has one or more unlimited dimensions. The data * is appended by a hyperslab that is contained in several chunks (for * example, appending 2-dim planes along the slowest changing dimension * in the 3-dim dataset and each plane is covered by 4 chunks). * Level: * User Level * Guarantees: * o Readers will see the modified dimension sizes after the Writer * finishes HDF5 metadata updates and issues H5Fflush or H5Oflush calls. * o Readers will see newly appended data after the Writer finishes * the flush operation. * * Preconditions: * o Readers are not allowed to modify the file. * o All datasets that are modified by the Writer exist when the * Writer opens the file. * o All datasets that are modified by the Writer exist when a Reader * opens the file. * * Main Success Scenario: * 1. An application creates a file with required objects (groups, * datasets, and attributes). * 2. The Writer opens the file and datasets in the file and starts * adding data using H5Dwrite call with a hyperslab selection that * spans several chunks. * 3. A Reader opens the file and a dataset in a file; if the size of * the unlimited dimension has changed, reads the appended data back. * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * */ /* Created: Albert Cheng, 2013/6/1 */ #include "h5test.h" /* This test uses many POSIX things that are not available on * Windows.
