H5Pset_fletcher32
(
hid_t plist_id
)
H5Pset_fletcher32
sets the Fletcher32 checksum filter
in the dataset or group creation property list plist_id
.
As a result of this fix, an HDF5 Library of Release 1.6.0 through Release 1.6.2 cannot read a dataset created or written with Release 1.6.3 or later if the dataset was created with the checksum filter and the filter is enabled in the reading library. (Libraries of Release 1.6.3 and later understand the earlier error and comensate appropriately.)
Work-around:
An HDF5 Library of Release 1.6.2 or earlier will be able to read
a dataset created or written with the checksum filter by an
HDF5 Library of Release 1.6.3 or later if the checksum filter is
disabled for the read operation. This can be accomplished via a call to
H5Pset_edc_check
with the value H5Z_DISABLE_EDC
in the second parameter.
This has the obvious drawback that the application will be unable
to verify the checksum, but the data does remain accessible.
