Whoops! Pasted in a incorrect version of the _read_records() patch.
The "offset" needs to be an intermediate variable
------ _read_records() in TableExtension.pyx ------
def _read_records(self, hsize_t start, hsize_t nrecords, object recarr):
cdef long buflen, offset
cdef void *rbuf
cdef int ret
# Correct the number of records to read, if needed
if (start + nrecords) > self.totalrecords:
nrecords = self.totalrecords - start
# Get the pointer to the buffer data area
buflen = NA_getBufferPtrAndSize(recarr._data, 1, &rbuf)
# SS 2006-0506 - Correct the offset
offset = recarr._byteoffset
rbuf = <void *>(<char *>rbuf + offset)
# Read the records from disk
Py_BEGIN_ALLOW_THREADS
ret = H5TBOread_records(self.dataset_id, self.type_id, start,
nrecords, rbuf)
Py_END_ALLOW_THREADS
if ret < 0:
raise HDF5ExtError("Problems reading records.")
# Convert some HDF5 types to Numarray after reading.
self._convertTypes(recarr, nrecords, 1)
return nrecords
