Hi Vladimir, I was able to reproduce this issue in a C example, and have entered a bug report for it. For your reference it is HDFFV-9277.
Thank you for reporting this! -Barbara [email protected]<mailto:[email protected]> From: Hdf-forum [mailto:[email protected]] On Behalf Of Vladimír Šedenka Sent: Monday, March 30, 2015 12:37 PM To: [email protected] Subject: [Hdf-forum] MATLAB Unable to delete attribute in dense storage Dear all, I am facing a problem when trying to delete HDF5 attribute stored in dense storage in MATLAB R2014b. The test code (below) works for small data size (10x10) but causes "red errors" for bigger data (100x100). close all; clear all; clc; fileName = 'H5A_delete.h5'; groupName = 'test'; attrName = 'testAttribute'; data = 1.23*ones(100, 100); if exist(fileName, 'file') delete(fileName); end faplID = H5P.create('H5P_FILE_ACCESS'); H5P.set_libver_bounds(faplID, 'H5F_LIBVER_18', 'H5F_LIBVER_LATEST'); fileID = H5F.create(fileName, 'H5F_ACC_TRUNC', 'H5P_DEFAULT', faplID); H5P.close(faplID); groupID = H5G.create(fileID, groupName, 'H5P_DEFAULT', 'H5P_DEFAULT', 'H5P_DEFAULT'); spaceID = H5S.create_simple(length(size(data)), fliplr(size(data)), []); % attribute creation acplID = H5P.create('H5P_ATTRIBUTE_CREATE'); attrID = H5A.create(groupID, attrName, 'H5T_IEEE_F64LE', spaceID, acplID); H5P.close(acplID); % writing attribute value H5A.write(attrID, 'H5T_NATIVE_DOUBLE', data); H5A.close(attrID); H5S.close(spaceID); H5G.close(groupID); H5F.close(fileID); clear acplID attrID data faplID fileID groupID spaceID; % fileattrib(filename, '+w'); fileID = H5F.open(fileName, 'H5F_ACC_RDWR', 'H5P_DEFAULT'); groupID = H5G.open(fileID, groupName); H5A.delete(groupID, attrName); H5G.close(groupID); H5F.close(fileID); Error messages: Error using hdf5lib2 The HDF5 library encountered an error and produced the following stack trace information: H5FD_windows_read addr overflow H5FD_read driver read request failed H5F_accum_read driver read request failed H5F_block_read read through metadata accumulator failed H5HF_huge_op_real can't read 'huge' object's data from the file H5HF_huge_op unable to operate on heap object H5HF_op can't operate on 'huge' object from fractal heap H5A_dense_delete_bt2_cb heap op callback failed H5B2_delete_node iterator function failed H5B2_hdr_delete unable to delete B-tree nodes H5SL_insert_common can't insert duplicate key H5SL_insert can't create new skip list node H5FS_sect_link_rest can't insert free space node into merging skip list H5FS_sect_link can't add section to non-size tracking data structures H5FS_sect_add can't insert free space section into skip list H5MF_xfree can't add section to file free space H5HF_cache_hdr_dest unable to free fractal heap header H5HF_cache_hdr_clear unable to destroy fractal heap header H5C_flush_single_entry can't clear entry H5C_unprotect Can't flush.
